Note release version goes backwards. Version now follows openbsd version
numbering.
No changes available.
Patched to eliminate compilation warnings on netbsd.
When $HOME environment variable is set, e.g. in pkgrsc where a fake
homedir is injected, ~ is expanded to $HOME while ~user is expanded
to the passwd(5) home_dir field leading to inconsistency in the test.
No PKGREVISION bump since that change only affects tests.
pkgsrc changes:
- Add patch-nls_Makefile.in to avoid +x bit in *.cat files
- Remove no longer needed patches (all applied upstream):
patch-ed.chared.c, patch-ed.inputl.c, patch-nls-catgen, patch-sh.func.c,
patch-tw.init.c
Changes:
V6.21.00 - 20190508
-------------------
- Abort history loading on words and lines too long
https://bugzilla.redhat.com/show_bug.cgi?id=1598502
- PR/37: Introduce GetCmdChar() to avoid open coding array access.
make closem() not close sockets so as not to affect nss_ldap.
tcsh never creates sockets so that's ok (Miloslav Trmac)
- PR/597: Make rmstar work with aliased rm
- convert match() from recursive to backtracking.
- Handle 8 bit characters in bindkey (Werner Fink)
- Look for tgetent in libtinfo as well (Werner Fink)
- Don't play pointer tricks that are undefined in modern c (Brooks Davis)
- Fix out of bounds read (Brooks Davis)
- Fix type of read in prompt confirmation (eg. rmstar) (David Kaspar)
- PR/471: Delay arginp parsing
ok <kim>, thanks!
The patches fix:
1. Under certain circumstances, the glob expansion code did not remove
backslashes escaping characters in directory names (or portions of a
pattern preceding a slash).
2. When an alias value ends with an unquoted literal tab (not part of a quoted
string or comment), alias expansion cannot correctly detect the end of the
alias value after expanding it.
3. There are several incompatibilities in how bash-5.0 processes pathname
expansion (globbing) of filename arguments that have backslashes in the
directory portion.
4. In bash-5.0, the `wait' builtin without arguments waits for all children
of the shell. This includes children it `inherited' at shell invocation time.
This patch modifies the behavior to not wait for these inherited children,
some of which might be long-lived.
5. In certain cases, bash optimizes out a fork() call too early and prevents
traps from running.
6. Bash-5.0 did not build successfully if SYSLOG_HISTORY was defined without
also defining SYSLOG_SHOPT.
7. Running `exec' when job control was disabled, even temporarily, but after it
had been initialized, could leave the terminal in the wrong process group for
the executed process.

Changelog
=========
Release 2019-02-18:
- libgetopt: The undocumented variable "_sp" from SVr4 has been renamed
to "opt_sp" and (on platforms that support "#pragma weak") there
is a weak reference _sp to that new variable, giving backwards
compatibility.
The reason for doing this is to make sure that people on Illumos
or Oracle Solaris, who still have an outdated version of getopt()
in their local libc, do not try to link the Bourne Shell only
against their old getopt(). If they did this, they would not get
the documented enhanced getopt() features from the Bourne Shell.
- Bourne Shell: The shell now uses "opt_sp" as the name for the
undocumented additional getopt() interface from AT&T. This has
been done to avoid being able to link the Bourne Shell on
Illumos or Oracle Solaris without using our libgetopt. If this
was done, we could not support UNIX/MULTICS style long options
and we could not support -help/--help, since the latter is
implemented via long options that are not an alias to short
options.
- Bourne Shell: added a new timestamp to the Bourne Shell version.
Release 2018-11-21:
- Bourne Shell: make it exit the whole shell with set -e after a command
substitution failed on the right side of a variable assignment
that has no command. This is required by POSIX.
- Bourne Shell: added a unit tests for the above case.
- Bourne Shell: New version date set to 2018-12-08 the this change.
Release 2019-01-22:
- bsh / Bourne Shell / star: the function hop_dirs() no longer checks
for p2 != NULL before calling *p2 = '/' as p2 has
been granted to be != NULL from a break with
strchr(p, '/') == NULL

# fish 3.0.0 (released December 28, 2018)
fish 3 is a major release, which introduces some breaking changes alongside improved functionality. Although most existing scripts will continue to work, they should be reviewed against the list contained in the 3.0b1 release notes below.
Compared to the beta release of fish 3.0b1, fish version 3.0.0:
- builds correctly against musl libc (#5407)
- handles huge numeric arguments to `test` correctly (#5414)
- removes the history colouring introduced in 3.0b1, which did not always work correctly
There is one significant known issue which was not able to be corrected before the release:
- fish 3.0.0 builds on Cygwin (#5423), but does not run correctly (#5426) and will result in a hanging terminal when started. Cygwin users are encouraged to continue using 2.7.1 until a release which corrects this is available.
If you are upgrading from version 2.7.1 or before, please also review the release notes for 3.0b1 (included below).

# fish 3.0b1 (released December 11, 2018)
fish 3 is a major release, which introduces some breaking changes alongside improved functionality. Although most existing scripts will continue to work, they should be reviewed against the list below.
## Notable non-backward compatible changes
- Process and job expansion has largely been removed. `%` will no longer perform these expansions, except for `%self` for the PID of the current shell. Additionally, job management commands (`disown`, `wait`, `bg`, `fg` and `kill`) will expand job specifiers starting with `%` (#4230, #1202).
- `set x[1] x[2] a b`, to set multiple elements of an array at once, is no longer valid syntax (#4236).
- A literal `{}` now expands to itself, rather than nothing. This makes working with `find -exec` easier (#1109, #4632).
- Literally accessing a zero-index is now illegal syntax and is caught by the parser (#4862). (fish indices start at 1)
- Successive commas in brace expansions are handled in less surprising manner. For example, `{,,,}` expands to four empty strings rather than an empty string, a comma and an empty string again (#3002, #4632).
- `for` loop control variables are no longer local to the `for` block (#1935).
- Variables set in `if` and `while` conditions are available outside the block (#4820).
- Local exported (`set -lx`) vars are now visible to functions (#1091).
- The new `math` builtin (see below) does not support logical expressions; `test` should be used instead (#4777).
- Range expansion will now behave sensibly when given a single positive and negative index (`$foo[5..-1]` or `$foo[-1..5]`), clamping to the last valid index without changing direction if the list has fewer elements than expected.
- `read` now uses `-s` as short for `--silent` (à la `bash`); `--shell`'s abbreviation (formerly `-s`) is now `-S` instead (#4490).
- `cd` no longer resolves symlinks. fish now maintains a virtual path, matching other shells (#3350).
- `source` now requires an explicit `-` as the filename to read from the terminal (#2633).
- Arguments to `end` are now errors, instead of being silently ignored.
- The names `argparse`, `read`, `set`, `status`, `test` and `[` are now reserved and not allowed as function names. This prevents users unintentionally breaking stuff (#3000).
- The `fish_user_abbreviations` variable is no longer used; abbreviations will be migrated to the new storage format automatically.
- The `FISH_READ_BYTE_LIMIT` variable is now called `fish_byte_limit` (#4414).
- Environment variables are no longer split into arrays based on the record separator character on startup. Instead, variables are not split, unless their name ends in PATH, in which case they are split on colons (#436).
- The `history` builtin's `--with-time` option has been removed; this has been deprecated in favor of `--show-time` since 2.7.0 (#4403).
- The internal variables `__fish_datadir` and `__fish_sysconfdir` are now known as `__fish_data_dir` and `__fish_sysconf_dir` respectively.
## Deprecations
With the release of fish 3, a number of features have been marked for removal in the future. All users are encouraged to explore alternatives. A small number of these features are currently behind feature flags, which are turned on at present but may be turned off by default in the future.
A new feature flags mechanism is added for staging deprecations and breaking changes. Feature flags may be specified at launch with `fish --features ...` or by setting the universal `fish_features` variable. (#4940)
- The use of the `IFS` variable for `read` is deprecated; `IFS` will be ignored in the future (#4156). Use the `read --delimiter` option instead.
- The `function --on-process-exit` switch will be removed in future (#4700). Use the `fish_exit` event instead: `function --on-event fish_exit`.
- `$_` is deprecated and will removed in the future (#813). Use `status current-command` in a command substitution instead.
- `^` as a redirection deprecated and will be removed in the future. (#4394). Use `2>` to redirect stderr. This is controlled by the `stderr-nocaret` feature flag.
- `?` as a glob (wildcard) is deprecated and will be removed in the future (#4520). This is controlled by the `qmark-noglob` feature flag.
## Notable fixes and improvements
### Syntax changes and new commands
- fish now supports `&&` (like `and`), `||` (like `or`), and `!` (like `not`), for better migration from POSIX-compliant shells (#4620).
- Variables may be used as commands (#154).
- fish may be started in private mode via `fish --private`. Private mode fish sessions do not have access to the history file and any commands evaluated in private mode are not persisted for future sessions. A session variable `$fish_private_mode` can be queried to detect private mode and adjust the behavior of scripts accordingly to respect the user's wish for privacy.
- A new `wait` command for waiting on backgrounded processes (#4498).
- `math` is now a builtin rather than a wrapper around `bc` (#3157). Floating point computations is now used by default, and can be controlled with the new `--scale` option (#4478).
- Setting `$PATH` no longer warns on non-existent directories, allowing for a single $PATH to be shared across machines (eg via dotfiles) (#2969).
- `while` sets `$status` to a non-zero value if the loop is not executed (#4982).
- Command substitution output is now limited to 10 MB by default, controlled by the `fish_read_limit` variable (#3822). Notably, this is larger than most operating systems' argument size limit, so trying to pass argument lists this size to external commands has never worked.
- The machine hostname, where available, is now exposed as the `$hostname` reserved variable. This removes the dependency on the `hostname` executable (#4422).
- Bare `bind` invocations in config.fish now work. The `fish_user_key_bindings` function is no longer necessary, but will still be executed if it exists (#5191).
- `$fish_pid` and `$last_pid` are available as replacements for `%self` and `%last`.
### New features in commands
- `alias` has a new `--save` option to save the generated function immediately (#4878).
- `bind` has a new `--silent` option to ignore bind requests for named keys not available under the current terminal (#4188, #4431).
- `complete` has a new `--keep-order` option to show the provided or dynamically-generated argument list in the same order as specified, rather than alphabetically (#361).
- `exec` prompts for confirmation if background jobs are running.
- `funced` has a new `--save` option to automatically save the edited function after successfully editing (#4668).
- `functions` has a new ` --handlers` option to show functions registered as event handlers (#4694).
- `history search` supports globs for wildcard searching (#3136) and has a new `--reverse` option to show entries from oldest to newest (#4375).
- `jobs` has a new `--quiet` option to silence the output.
- `read` has a new `--delimiter` option for splitting input into arrays (#4256).
- `read` writes directly to stdout if called without arguments (#4407).
- `read` can now read individual lines into separate variables without consuming the input in its entirety via the new `/--line` option.
- `set` has new `--append` and `--prepend` options (#1326).
- `set` has a new `--show` option to show lots of information about variables (#4265).
- `string match` with an empty pattern and `--entire` in glob mode now matches everything instead of nothing (#4971).
- `string split` supports a new `--no-empty` option to exclude empty strings from the result (#4779).
- `string` has new subcommands `split0` and `join0` for working with NUL-delimited output.
- `string` no longer stops processing text after NUL characters (#4605)
- `string escape` has a new `--style regex` option for escaping strings to be matched literally in `string` regex operations.
- `test` now supports floating point values in numeric comparisons.
### Interactive improvements
- A pipe at the end of a line now allows the job to continue on the next line (#1285).
- Italics and dim support out of the box on macOS for Terminal.app and iTerm (#4436).
- `cd` tab completions no longer descend into the deepest unambiguous path (#4649).
- Pager navigation has been improved. Most notably, moving down now wraps around, moving up from the commandline now jumps to the last element and moving right and left now reverse each other even when wrapping around (#4680).
- Typing normal characters while the completion pager is active no longer shows the search field. Instead it enters them into the command line, and ends paging (#2249).
- A new input binding `pager-toggle-search` toggles the search field in the completions pager on and off. By default, this is bound to Ctrl-S.
- Searching in the pager now does a full fuzzy search (#5213).
- The pager will now show the full command instead of just its last line if the number of completions is large (#4702).
- Abbreviations can be tab-completed (#3233).
- Tildes in file names are now properly escaped in completions (#2274).
- Wrapping completions (from `complete --wraps` or `function --wraps`) can now inject arguments. For example, `complete gco --wraps 'git checkout'` now works properly (#1976). The `alias` function has been updated to respect this behavior.
- Path completions now support expansions, meaning expressions like `python ~/<TAB>` now provides file suggestions just like any other relative or absolute path. (This includes support for other expansions, too.)
- Autosuggestions try to avoid arguments that are already present in the command line.
- Notifications about crashed processes are now always shown, even in command substitutions (#4962).
- The screen is no longer reset after a BEL, fixing graphical glitches (#3693).
- vi-mode now supports ';' and ',' motions. This introduces new {forward,backward}-jump-till and repeat-jump{,-reverse} bind functions (#5140).
- The `*y` vi-mode binding now works (#5100).
- True color is now enabled in neovim by default (#2792).
- Terminal size variables (`$COLUMNS`/`$LINES`) are now updated before `fish_prompt` is called, allowing the prompt to react (#904).
- Multi-line prompts no longer repeat when the terminal is resized (#2320).
- `xclip` support has been added to the clipboard integration (#5020).
- The Alt-P keybinding paginates the last command if the command line is empty.
- `$cmd_duration` is no longer reset when no command is executed (#5011).
- Deleting a one-character word no longer erases the next word as well (#4747).
- Token history search (Alt-Up) omits duplicate entries (#4795).
- The `fish_escape_delay_ms` timeout, allowing the use of the escape key both on its own and as part of a control sequence, was applied to all control characters; this has been reduced to just the escape key.
- Completing a function shows the description properly (#5206).
- Added completions for
- `ansible`, including `ansible-galaxy`, `ansible-playbook` and `ansible-vault` (#4697)
- `bb-power` (#4800)
- `bd` (#4472)
- `bower`
- `clang` and `clang++` (#4174)
- `conda` (#4837)
- `configure` (for autoconf-generated files only)
- `curl`
- `doas` (#5196)
- `ebuild` (#4911)
- `emaint` (#4758)
- `eopkg` (#4600)
- `exercism` (#4495)

- `unzip`
- `virsh` (#5113)
- `xclip` (#5126)
- `xsv`
- `zfs` and `zpool` (#4608)
- Lots of improvements to completions (especially `darcs` (#5112), `git`, `hg` and `sudo`).
- Completions for `yarn` and `npm` now require the `all-the-package-names` NPM package for full functionality.
- Completions for `bower` and `yarn` now require the `jq` utility for full functionality.
- Improved French translations.
### Other fixes and improvements
- Significant performance improvements to `abbr` (#4048), setting variables (#4200, #4341), executing functions, globs (#4579), `string` reading from standard input (#4610), and slicing history (in particular, `$history[1]` for the last executed command).
- Fish's internal wcwidth function has been updated to deal with newer Unicode, and the width of some characters can be configured via the `fish_ambiguous_width` (#5149) and `fish_emoji_width` (#2652) variables. Alternatively, a new build-time option INTERNAL_WCWIDTH can be used to use the system's wcwidth instead (#4816).
- `functions` correctly supports `-d` as the short form of `--description`. (#5105)
- `/etc/paths` is now parsed like macOS' bash `path_helper`, fixing $PATH order (#4336, #4852) on macOS.
- Using a read-only variable in a `for` loop produces an error, rather than silently producing incorrect results (#4342).
- The universal variables filename no longer contains the hostname or MAC address. It is now at the fixed location `.config/fish/fish_variables` (#1912).
- Exported variables in the global or universal scope no longer have their exported status affected by local variables (#2611).
- Major rework of terminal and job handling to eliminate bugs (#3805, #3952, #4178, #4235, #4238, #4540, #4929, #5210).
- Improvements to the manual page completion generator (#2937, #4313).
- `suspend --force` now works correctly (#4672).
- Pressing Ctrl-C while running a script now reliably terminates fish (#5253).
### For distributors and developers
- fish ships with a new build system based on CMake. CMake 3.2 is the minimum required version. Although the autotools-based Makefile and the Xcode project are still shipped with this release, they will be removed in the near future. All distributors and developers are encouraged to migrate to the CMake build.
- Build scripts for most platforms no longer require bash, using the standard sh instead.
- The `hostname` command is no longer required for fish to operate.

====================
Xonsh Change Log
====================
v0.8.8
====================
**Added:**
* ``vox new`` has an added ``-p --interpreter`` flag for choosing the python interpreter to use for virtualenv creation
* The default Python intrepreter vox uses to create virtual environments can be set using the ``$VOX_DEFAULT_INTERPRETER`` environment variable.
**Changed:**
* ``lib.ChainDB`` now resolves results to the type of the inputs if possible
v0.8.7
====================
**Added:**
* New xonsh syntax ``pf`` strings -- combining path strings with f-strings.
Usage:
.. code-block:: bash
gil@bad_cat ~ $ repos = 'github.com'
gil@bad_cat ~ $ pf"~/{repos}"
PosixPath('/home/gil/github.com')
gil@bad_cat ~ $ pf"{$HOME}"
PosixPath('/home/gil')
gil@bad_cat ~ $ pf"/home/${'US' + 'ER'}"
PosixPath('/home/gil')
**Fixed:**
* Set ``ls`` to ``predict_true`` in ``default_threadable_predictors``. This prevents ``ls`` on OSX
from being flagged on OSX as unthreadable (incorrectly) because it relies on ``ncurses``.
v0.8.6
====================
**Added:**
* Doco about how to update xonsh and how to set and unset environment variables
**Fixed:**
* Updated behavior of the ``cat`` coreutils function so that it properly
handles as vareity of cases such as:
* Exits after concatenating normal files which have a finite size
* Continues to run for special files which do not have a size,
such as ``/dev/random``
* Is interruptable in all cases with Crtl-C.
* Callable aliases were not properly raising a ``CalledProcessError`` when they
returned a non-zero exist status when ``$RAISE_SUBPROC_ERROR = True``. This has
been fixed.
* Fixed interpretation of color names with PTK2 and Pygments 2.3.1.
v0.8.5
====================
**Added:**
* Add alias to `base16 shell <https://github.com/chriskempson/base16-shell>`_
* Installation / Usage
1. To install use pip
.. code-block:: bash
python3 -m pip install xontrib-base16-shell
2. Add on ``~/.xonshrc``
.. code:: python
:number-lines:
$BASE16_SHELL = $HOME + "/.config/base16-shell/"
xontrib load base16_shell
3. See image
.. image:: https://raw.githubusercontent.com/ErickTucto/xontrib-base16-shell/master/docs/terminal.png
:width: 600px
:alt: terminal.png
* New ``DumbShell`` class that kicks in whenever ``$TERM == "dumb"``.
This usually happens in emacs. Currently, this class inherits from
the ``ReadlineShell`` but adds some light customization to make
sure that xonsh looks good in the resultant terminal emulator.
* Aliases from foreign shells (e.g. Bash) that are more than single expressions,
or contain sub-shell executions, are now evaluated and run in the foreign shell.
Previously, xonsh would attempt to translate the alias from sh-lang into
xonsh. These restrictions have been removed. For example, the following now
works:
.. code-block:: sh
$ source-bash 'alias eee="echo aaa \$(echo b)"'
$ eee
aaa b
* New ``ForeignShellBaseAlias``, ``ForeignShellFunctionAlias``, and
``ForeignShellExecAlias`` classes have been added which manage foreign shell
alias execution.
**Changed:**
* String aliases will now first be checked to see if they contain sub-expressions
that require evaluations, such as ``@(expr)``, ``$[cmd]``, etc. If they do,
then an ``ExecAlias`` will be constructed, rather than a simple list-of-strs
substitutiuon alias being used. For example:
.. code-block:: sh
$ aliases['uuu'] = "echo ccc $(echo ddd)"
$ aliases['uuu']
ExecAlias('echo ccc $(echo ddd)\n', filename='<exec-alias:uuu>')
$ uuu
ccc ddd
* The ``parse_aliases()`` function now requires the shell name.
* ``ForeignShellFunctionAlias`` now inherits from ``ForeignShellBaseAlias``
rather than ``object``.
**Fixed:**
* Fixed issues where the prompt-toolkit v2 shell would print an extra newline
after Python evaluations in interactive mode.
v0.8.4
====================
**Added:**
* Added the possibility of arbitrary paths to the help strings in ``vox activate`` and
``vox remove``; also updated the documentation accordingly.
* New ``xonsh.aliases.ExecAlias`` class enables multi-statement aliases.
* New ``xonsh.ast.isexpression()`` function will return a boolean of whether
code is a simple xonsh expression or not.
* Added top-level ``run-tests.xsh`` script for safely running the test suite.
**Changed:**
* String aliases are no longer split with ``shlex.split()``, but instead use
``xonsh.lexer.Lexer.split()``.
* Update xonsh/prompt/cwd.py _collapsed_pwd to print 2 chars if a directory begins with "."
* test which determines whether a directory is a virtualenv
previously it used to check the existence of 'pyvenv.cfg'
now it checks if 'bin/python' is executable
**Fixed:**
* Fixed issue with ``and`` & ``or`` being incorrectly tokenized in implicit
subprocesses. Auto-wrapping of certain subprocesses will now correctly work.
For example::
$ echo x-and-y
x-and-y
* Fix EOFError when press `control+d`
* fix no candidates if no permission files in PATH
* Fixed interpretation of color names with PTK2 and Pygments 2.3.
* Several ResourceWarnings: unclosed file in tests
* AttributeError crash when using --timings flag
* issue #2929
v0.8.3
====================
**Added:**
* Dociumentation paragrapgh about gow to run xonsh in Emacs shell
**Changed:**
* Updated what pip requirements are needed to build the documnetaion
* ``$XONSH_TRACEBACK_LOGFILE`` now beside strings also accepts ``os.PathLike``
objects.
* Updated vended version of ``ply`` to 3.11
* Deprecation warnings now print from stacklevel 3.
**Fixed:**
* Annotation assignment statements (e.g. ``x : int = 42``) are now supported.
* Fixed error output wording for fg and bg commands
* Flake8 errors
* xonsh can now properly parse import statements with trailing comma within
parentheses, e.g.::
from x import (y, z,)
* ResourceWarning: unclosed scandir iterator in imphooks.py
* Removed use of deprecated ``inspect.formatargspec()`` for ``inspect.signature()``
* ``Makefile`` directive that updates vended version of ``ply``
v0.8.2
====================
**Changed:**
* Now there is only a single instance of ``string.Formatter()`` in the
code base, which is called ``xonsh.tools.FORMATTER``.
**Fixed:**
* f-strings (``f"{expr}"``) are now fully capable of executing xonsh expressions.
The one exception to this is that ``![cmd]`` and ``!(cmd)`` don't work because
the ``!`` character interferes with Python string formatting. If you need to
run subprocesses inside of f-strings, use ``$[cmd]`` and ``$(cmd)`` instead.
* Fixed occasional "no attribute 'settitle' error"
v0.8.1
====================
**Added:**
* ``SubprocSpec`` has a new ``pipeline_index`` integer attribute that indicates
the commands position in a pipeline. For example, in
.. code-block:: sh
p = ![ls -l | grep x]
The ``ls`` command would have a pipeline index of 0
(``p.specs[0].pipeline_index == 0``) and ``grep`` would have a pipeline index
of 1 (``p.specs[1].pipeline_index == 1``). This may be usefule in callable
alaises which recieve the spec as an argument.
**Changed:**
* Removed ``fish`` from list of supported foreign shells in the wizard.
* Circle CI config updated to use a pinned version of ``black`` (18.9b0)
* Pytest plugin now uses ``xonsh.main.setup()`` to setup test environment.
* Linux platform discovery will no longer use ``platform.linux_distribution()``
on Python >=3.6.6. due to pending deprecation warning.
* Updated Linux Guide as Xonsh is now available in Arch Linux official repositories.
**Fixed:**
* Builtin dynamic proxies and deprecation warning proxies were not deleting
attributes and items properly.
* Fixed stdout/sdterr writing infinite recurssion error that would occur in
long pipelines of callable aliases.
* Fixed a bug which under very rare conditions could cause the shell
to die with PermissionError exception while sending SIGSTOP signal
to a child process.
* Fixed further raw string deprecation warnings thoughout the code base.
v0.8.0
====================
**Added:**
* Windows CI jobs on Azure Pipelines
* The ``cryptop`` command will no longer have its output captured
by default.
* Added new env-var ``PTK_STYLE_OVERRIDES``. The variable is
a dictionary containing custom prompt_toolkit style definitions.
For instance::
$PTK_STYLE_OVERRIDES['completion-menu'] = 'bg:#333333 #EEEEEE'
will provide for more visually pleasing completion menu style whereas::
$PTK_STYLE_OVERRIDES['bottom-toolbar'] = 'noreverse'
will prevent prompt_toolkit from inverting the bottom toolbar colors
(useful for powerline extension users)
Note: This only works with prompt_toolkit 2 prompter.
**Changed:**
* All ``__xonsh_*__`` builtins have been migrated to a ``XonshSession`` instance at
``__xonsh__``. E.g. ``__xonsh_env__`` is now ``__xonsh__.env``.
* Other xonsh-specific builtins (such as ``XonshError``) have been proxied to
the ``__xonsh__`` session object as well.
**Deprecated:**
* All ``__xonsh_*__`` builtins are deprected. Instead, the corresponding
``__xonsh__.*`` accessor should be used. The existing ``__xonsh_*__`` accessors
still work, but issue annoying warnings.
**Fixed:**
* Fixed deprecation warnings from unallowed escape sequences as well as importing abstract base classes directly from ``collections``
* Fix for string index error in stripped prefix
* bash_completions to include special characters in lprefix
Previously, glob expansion characters would not be included in lprefix for replacement
.. code-block:: sh
$ touch /tmp/abc
$ python
>>> from bash_completion import bash_completions
>>>
>>> def get_completions(line):
... split = line.split()
... if len(split) > 1 and not line.endswith(' '):
... prefix = split[-1]
... begidx = len(line.rsplit(prefix)[0])
... else:
... prefix = ''
... begidx = len(line)
... endidx = len(line)
... return bash_completions(prefix, line, begidx, endidx)
...
>>> get_completions('ls /tmp/a*')
({'/tmp/abc '}, 0)
Now, lprefix begins at the first special character:
.. code-block:: sh
$ python
>>> from bash_completion import bash_completions
>>>
>>> def get_completions(line):
... split = line.split()
... if len(split) > 1 and not line.endswith(' '):
... prefix = split[-1]
... begidx = len(line.rsplit(prefix)[0])
... else:
... prefix = ''
... begidx = len(line)
... endidx = len(line)
... return bash_completions(prefix, line, begidx, endidx)
...
>>> get_completions('ls /tmp/a*')
({'/tmp/abc '}, 7)
* The ``xonsh.main.setup()`` function now correctly passes the
``shell_type`` argument to the shell instance.
* try_subproc_toks now works for subprocs with trailing and leading whitespace
Previously, non-greedy wrapping of commands would fail if they had leading and trailing whitespace:
.. code-block:: sh
$ true && false || echo a
xonsh: For full traceback set: $XONSH_SHOW_TRACEBACK = True
NameError: name 'false' is not defined
$ echo; echo && echo a
xonsh: For full traceback set: $XONSH_SHOW_TRACEBACK = True
NameError: name 'echo' is not defined
Now, the commands are parsed as expected:
.. code-block:: sh
$ true && false || echo a
a
$ echo; echo && echo a
a
v0.7.10
====================
**Added:**
* 'off' can be passed as falsy value to all flags accepting boolean argument.
- DragonFly BSD support
* Format strings (f-strings) now allow environment variables to be looked up.
For example, ``f"{$HOME}"`` will yield ``"/home/user"``. Note that this will
look up and fill in the ``detype()``-ed version of the environment variable,
i.e. it's native string representation.
**Changed:**
* Running ``aurman`` command will now be predicted to be unthreaded by default.
**Fixed:**
* The xonsh ``xonfig wizard`` would crash if an unknown foreign shell was
provided. This has been fixed.
* The ``hg split`` command will now predict as unthreadable.
* Fixed path completer crash on attempted f-string completion
v0.7.9
====================
**Added:**
* The python-mode ``@(expr)`` syntax may now be used inside of subprocess
arguments, not just as a stand-alone argument. For example:
.. code-block:: sh
$ x = 'hello'
$ echo /path/to/@(x)
/path/to/hello
This syntax will even properly expand to the outer product if the ``expr``
is a list (or other non-string iterable) of values:
.. code-block:: sh
$ echo /path/to/@(['hello', 'world'])
/path/to/hello /path/to/world
$ echo @(['a', 'b']):@('x', 'y')
a:x a:y b:x b:y
Previously this was not possible.
* New ``$DOTGLOB`` environment variable enables globs to match
"hidden" files which start with a literal ``.``. Set this
variable to ``True`` to get this matching behavior.
Cooresponding API changes have been made to
``xonsh.tools.globpath()`` and ``xonsh.tools.iglobpath()``
* New environment variable ``$FOREIGN_ALIASES_SUPPRESS_SKIP_MESSAGE``
enables the removal of skipping foreign alias messages.
* New ``--suppress-skip-message`` command line option for skipping
foreign alias messages when sourcing foreign shells.
**Fixed:**
* In Bash completions, if there are no files to source, a ``set()`` will
no longer be inserted into the completion script.
* Fixed issue with TAB completion in readline not replacing values
with spaces properly when the prefix was unquoted.
v0.7.8
====================
**Added:**
* ``xonsh.lib.collections.ChainDB``, a chain map which merges mergable fields
**Fixed:**
* Pass all params to voxapi.create
* PTK tab-completion now auto-accepts completion if only one option is present
(note that fix is only for PTK2)
v0.7.7
====================
**Added:**
* A xontrib which adds support for autojump to xonsh
* Added new env-var ``XONSH_HISTORY_MATCH_ANYWHERE``. If set to ``True`` then
up-arrow history matching will match existing history entries with the search
term located anywhere, not just at the beginning of the line. Default value is
``False``
**Changed:**
* Improved iteration over virtual environments in ``Vox.__iter__``
**Fixed:**
* Fix for ``Enter`` not returning from Control-R search buffer
* Fixed automatic wrapping of many subprocesses that spanned multiple lines via
line continuation characters with logical operators separating the commands.
For example, the following now works:
.. code-block:: sh
echo 'a' \
and echo 'b'
* Environment swapping would not properly reraise errors due to weird
Python name binding issue.
v0.7.6
====================
**Added:**
* Callable aliases may now accept a ``stack`` argument. If they do, then the
stack, as computed from the aliases call site, is provided as a list of
``FrameInfo`` objects (as detailed in the standard library ``inspect``
module). Otherwise, the ``stack`` parameter is ``None``.
* ``SubprocSpec`` now has a ``stack`` attribute, for passing the call stack
to callable aliases. This defaults to ``None`` if the spec does not
need the stack. The ``resolve_stack()`` method computes the ``stack``
attribute.
**Changed:**
* xonsh/environ.py
Exceptions are caught in the code executed under Env.swap()
**Fixed:**
* Scripts are now cached by their realpath, not just abspath.
* Fixed a potential crash (``AssertionError: wrong color format``) on Python 3.5 and prompt_toolkit 1.
* The ``completer`` command now correctly finds completion functions
when nested inside of other functions.
* Fixed a crash when using the ``$XONSH_STDERR_PREFIX/POSTFIX`` with
prompt_toolkit and Pygments 2.2.
v0.7.5
====================
**Fixed:**
* Recent command history in ptk2 prompt now returns most recently executed
commands first (as expected)
* Fixed a regression taat prevented the readline backend from beeing used. This
regression was caused by the new ansi-color names, which are incompatible with
pygments 2.2.
v0.7.4
====================
**Added:**
* New ``xonsh-cat`` command line utility, which is a xonsh replacement
for the standard UNIX ``cat`` command.
* The new ``xonsh.xoreutils.cat.cat_main()`` enables the ``xonsh.xoreutils.cat``
module to be run as a command line utility.
* New ``CommandsCache.is_only_functional_alias()`` and
``CommandsCache.lazy_is_only_functional_alias()`` methods for determining if
if a command name is only implemented as a function, and thus has no
underlying binary command to execute.
* ``xonsh.xontribs.xontribs_load()`` is a new first-class API for loading
xontribs via a Python function.
* ``$COMPLETIONS_DISPLAY`` now supports readline-like behavior on
prompt-toolkit v2.
**Changed:**
* The xonsh Jupyter kernel now will properly redirect the output of commands
such as ``git log``, ``man``, ``less`` and other paged commands to the client.
This is done by setting ``$PAGER = 'cat'``. If ``cat`` is not available
on the system, ``xonsh-cat`` is used instead.
* The ``setup()`` function for starting up a working xonsh has ``aliases``,
``xontribs``, and ``threadable_predictors`` as new additional keyword
arguments for customizing the loading of xonsh.
**Fixed:**
* Fixed a bug with converting new PTK2 colors names to old names when using PTK1 or Jupyter
as the shell type.
* ``CommandsCache.locate_binary()`` will now properly return None when
``ignore_alias=False`` and the command is only a functional alias,
such as with ``cd``. Previously, it would return the name of the
command.
* Fixed issue with ``$COMPLETIONS_DISPLAY`` raising an error on
prompt-toolkit v2 when the value was not set to ``multi``.
* ValueError when executing ``vox list``
v0.7.3
====================
**Added:**
* Add the ``PROMPT_TOOLKIT_COLOR_DEPTH`` environment to xonsh default environment.
Possible values are ``DEPTH_1_BIT``/``MONOCHROME``,
``DEPTH_4_BIT``/``ANSI_COLORS_ONLY``, ``DEPTH_8_BIT``/``DEFAULT``, or ``DEPTH_24_BIT``/``TRUE_COLOR``.
Note: not all terminals support all color depths.
* New way to fix unreadable default terminal colors on Windows 10. Windows 10
now supports true color in the terminal, so if prompt toolkit 2 is
installed Xonsh will use a style with hard coded colors instead of the
default terminal colors. This will give the same color experience as on linux an mac.
The behaviour can be disabled with ``$INTENSIFY_COLORS_ON_WIN``
environment variable.
* New ``JupyterShell`` for interactive interfacing with Jupyter.
**Changed:**
* All ansicolor names used in styles have ben updated to the color names used by prompt_toolkit 2.
The new names are are much easier to understand
(e.g. ``ansicyan``/``ansibrightcyan`` vs. the old ``#ansiteal``/``#ansiturquoise``). The names are automatically
translated back when using prompt_toolkit 1.
**Removed:**
* Removed support for pygments < 2.2.
**Fixed:**
* New ansi-color names fixes the problem with darker colors using prompt_toolkit 2 on windows.
* Fixed a problem with the color styles on prompt toolkit 2. The default pygment
style is no longer merged into style selected in xonsh.
* The JupyterKernel has been fixed from a rather broken state.
v0.7.2
====================
**Added:**
* ``history show`` builtin now supports optional ``-0`` parameter that switches
the output to null-delimited. Useful for piping history to external filters.
**Fixed:**
* If exception is raised in indir context manager, return to original directory
* Fixed issue that autocomplete menu does not display
at terminal's maximum height
v0.7.1
====================
**Added:**
* Added feature to aliases.
* ``xonsh.lib.os.rmtree()`` an rmtree which works on windows properly (even with
git)
**Changed:**
* set default value of ``$AUTO_SUGGEST_IN_COMPLETIONS=False``
* Use the ``pygments_cache.get_all_styles()`` function instead of
interacting directly with pygments.
**Fixed:**
* Fixed issue with ``$ARG<N>`` varaibles not being passed to subprocesses correctly.
* Fixed issue with multiline string inside of ``@(expr)`` in
unwrapped subprocesses. For example, the following now works::
echo @("""hello
mom""")
* ``CommandPipeline.output`` now does properly lazy, non-blocking creation of
output string. ``CommandPipeline.out`` remains blocking.
* Fix regression in ``INTENSIFY_COLORS_ON_WIN`` functionality due to prompt_toolkit 2 update.
* Fixed issue that can't insert quotation marks and double quotes
for completion.
* Fixed issue with ``SyntaxErrors`` being reported on the wrong line
when a block of code contained multiple implicit subprocesses.
* ``prompt_toolkit >= 2`` will start up even if Pygments isn't present
* Fixed a regression with ``xonfig styles`` reporting ``AttributeError: module 'pygments' has no attribute 'styles'``
* ptk dependent xontribs (that use custom keybindings) now work with both ptk1
and ptk2
* Fixed async tokenizing issue on Python v3.7.
v0.7.0
====================
**Added:**
* Added a hook for printing a spcial display method on an object.
* Support for ``prompt_toolkit 2.0``
* The ``--shell-type`` (``$SHELL_TYPE``) may now be specified using
shortcuts, such as ``rl`` for ``readline`` and ``ptk2`` for
``prompt_toolkit2``. See ``xonsh --help`` for a full listing
of available aliases.
**Fixed:**
- Restored AUGASSIGN_OPS definition, which was inadvertently removed.
v0.6.10
====================
**Added:**
* ``xonsh.lib.subprocess.check_output`` as a ``check_output`` drop in
**Fixed:**
* ``xonsh.lib.subprocess.run`` doesn't change dirs unless asked
v0.6.9
====================
**Added:**
* New xonsh standard library ``xonsh.lib`` subpackage
* ``xonsh.lib.os.indir`` a context manager for temporarily entering into a directory
* ``xonsh.lib.subprocess.run`` and ``xonsh.lib.subprocess.check_call``
subprocess stubs using ``xonsh`` as the backend
**Fixed:**
* update xoreutils._which.which() for python 3.x support.
* Fixed issue with incorrect strip lengths for prefixes with quotes in them
* Fixed bash script to also consider leading double quotes and not just single
quotes
* Launching xonsh with prompt_toolkit version 2.x no longer fails, and instead fallsback to readline shell. This is a patch for until prompt_toolkit 2.x support is fully implemented. See PR #2570
v0.6.8
====================
**Fixed:**
* completions relative to ``CDPATH`` only trigger when used with ``cd``
* Import of ``ctypes.util`` is now explictly performed, as needed.
Python v3.7 no longer imports this module along with ``ctypes``.
* Fixed issue with pygments-cache not properly generating a cache the first
time when using prompt-toolkit. This was due to a lingering lazy import
of ``pkg_resources`` that has been removed.
* Removed duplicate ``pip`` completer
* ``bash_completion`` no longer returns invalid prefix lengths for directories
containing escape file names
* Fixed error when using redirection (e.g., >) on Windows.
v0.6.7
====================
**Changed:**
* Xonsh live example has been re-added back to the documentation.
**Fixed:**
* Fixed issue where xonsh would fail to properly return the terminal prompt
(and eat up 100% CPU) after a failed subprocess command in interactive mode
if ``$RAISE_SUBPROC_ERROR = True``.
* ``xonsh.tokenize.tok_name`` no longer mutates the standard library ``tokenize.tok_name``.
A copy is made on import instead.
v0.6.6
====================
**Added:**
* A multipurpose add method to EnvPath. For example:
.. code-block:: xonshcon
$ $PATH
EnvPath(
['/usr/bin', '/usr/local/bin', '/bin']
)
$ $PATH.add('~/.local/bin', front=True); $PATH
EnvPath(
['/home/user/.local/bin', '/usr/bin', '/usr/local/bin', '/bin']
)
$ $PATH.add('/usr/bin', front=True, replace=True); $PATH
EnvPath(
['/usr/bin', '/home/user/.local/bin', '/usr/local/bin', '/bin']
)
* Added ``pygments-cache`` project in order to reduce startup time.
**Changed:**
* built_ins.py, corrected a typo.
* test/test_news.py
It now uses regex to verify the format of rst files
* Mercurial (``hg``) will no longer run in a threadable subprocess when
it is run in interactive mode.
**Fixed:**
* issue 2313
v0.6.5
====================
**Added:**
* Wizard ``FileInsterter`` node class now has ``dumps()`` method for
converting a mapping to a string to insert in a file.
**Fixed:**
* Fixed issue with ``xonfig wizard`` writer failing to write valid run control
files for environment variables that are containter types. In particular,
the storage of ``$XONSH_HISTORY_SIZE`` has been fixed.
v0.6.4
====================
**Changed:**
* Error message improved for sourcing foreign shells, when file cannot be found
or there is a syntax error.
**Fixed:**
* Fixed issues with readline completer tab completing entries
with spaces.
* Fixed ``xonsh.tools.columnize()`` bug the prevented single-row
input from being columnized correctly.
* Now honor ASYNC and AWAIT as keywords in tokenizer on
Python 3.7.
v0.6.3
====================
**Added:**
* Docs for using ``@(<expr>)`` as a way to run commands and a gotcha about
list of strings vs single string expressions.
* Ubuntu versions which xonsh is packaged for (with xonsh versions)
**Changed:**
* When reporting errors without a traceback (i.e. ``$XONSH_SHOW_TRACEBACK = False``) and the error is a ``XonshError``
the exception type is not longer printed.
* ``CommandPipeline.proc`` may now be ``None``, to accomodate when the process
fails to even start (i.e. a missing command or incorrect permisions).
**Fixed:**
* The ``curl`` command will now be run in a thread, which prevents documents that
do not end in a newline from writing over the next prompt and vice versa.
* Fix bug on Windows when ``PATHEXT`` environment variable did not exist.
This also fixes building the xonsh documentation on Windows.
* Fixed a bug in the `free_cwd <http://xon.sh/xontribs.html#free-cwd>`__ Windows Xontrib, which caused the prompt to error if the current directory is
deleted/renamed from an other process.
* Fixed issue with ``$XONSH_SHOW_TRACEBACK`` not being respected in subprocess
mode when the command could not be found or had incorrect permissions.
v0.6.2
====================
**Added:**
* Release tarballs now include licenses and minimal documentation for xonsh and ply
* Wizard now has a ``FileInserter`` node that allows blocks to be
inserted and replaced inside of a file. This adheres to conversion
rules fordumping as provided on this node.
* New ``xonsh.wizard.StateVisitor.flatten()`` method for flattening the
current state.
**Changed:**
* The xonsh startup wizard will only be triggered if no xonshrc files exist
and the file ``~/.local/config/xonsh/no-wizard`` is not present.
* The ``xonfig wizard`` command will now run write out to the xonshrc file.
* Wizard nodes ``Save`` and ``Load`` had their names changed to ``SaveJSON``
and ``LoadJSON``.
**Removed:**
* Static configuration is dead (``config.json``), long live run control (``xonshrc``)!
* The following evironment variables have been removed as they are no longer needed:
``$LOADED_CONFIG`` and ``$XONSHCONFIG``.
* Many support functions for static configuration have also been removed.
**Fixed:**
* Files starting with ``#`` are auto-escaped by TAB completion
v0.6.1
====================
**Added:**
* Support for MSYS2.
* New ``xonsh.main.setup()`` function for starting up xonsh in 3rd party
packages.
**Changed:**
* Updated CircleCI to use circle version 2.0
* Replaced StopIteration with return in CommandPipeline.iterraw.
* Xonsh run control now also looks for the XDG-compliant file
``~/.config/xonsh/rc.xsh`` at startup.
**Fixed:**
* Clean out ``$LINES`` and ``$COLUMNS`` if set, preventing some programs from drawing weirdly
* cat from xoreutils now outputs in configured encoding
* Fixed hanging issue with pipelines whose middle processes exit before the
first or last process.
* Fixed issue where xonsh would deduplicate spaces from bash autocompletions.
* Fixed failing redirections from stderr to stdout when the command
being executed was a callable alias.
* Ensure that the ``free_cwd`` contrib can only be active on pure Windows.
* Made an exceptional case in ``iglobpath()`` more robust when Python globbing
fails for due to strange scrandir issue.
* Unexpected process suspension on Cygwin and MSYS2.
* ``$XONSH_APPEND_NEWLINE`` will now default to True when in interactive mode.
* Fixed issue with uncalled lambdas being run in subproc mode.
* Lambda nodes not have proper line and column numbers in AST.
* Properly throw ``SyntaxError`` when no kwargs are defined
in a kwarg-only function. This used to throw a
``TypeError: 'NoneType' object is not iterable``.
* Addressed issue where encoding and errors were None when teeing output.
* Commands like ``git c`` would complete to ``git 'checkout '`` because git adds an extra space
to the end of the completion, which was being captured in the completion. Xonsh now fixes the git issue
while retaining all whitespace when there is other internal whitespace.
v0.6.0
====================
**Added:**
* Added an alias command, matching bash's implementation, available as part of bashisms.
* New ``$AUTO_SUGGEST_IN_COMPLETIONS`` environment variable that enables/disables
whether the auto-suggestion result appears in the tab completions.
* Added ``__add__()`` and ``__radd__()`` methods to ``EnvPath``.
* Xonsh now supports f-strings, as in Python v3.6+.
* Added ``ipython`` as unthreadable in command cache threadabilty predictors.
* Added ``whole_word_jumping`` xontrib
* Added ``$XONSH_APPEND_NEWLINE`` environment variable
* Support for PEP 515: Underscores in Numeric Literals
* ``xonsh.color_tools.make_palette()``
Simple rename of the pre-existing
``xonsh.color_tools.make_pallete()`` function.
* ``xonsh.tools.decorator()`` function/method decorator.
This allows for an API function to be annotated with a
decorator that documents deprecation, while also tying in
functionality that will warn a user that the function has
been deprecated, and, raise an ``AssertionError`` if the
function has passed its expiry date.
* New xontrib ``schedule`` (Xonsh Task Scheduler)
**Changed:**
* ``on_pre_prompt`` is now fired before prompt calculations are made, allowing modifications to the prompt.
* ``emacsclient`` will now return false in the threadable predictors.
* Improved the autopair behavior to match that of popular code editors.
* Moved the lazy ``pkg_resources`` package back to its original
place. The will hopefully address some of the slowdown issues
experiances on some platforms.
* When xonsh is used to run an ``xsh`` script, the ``xonshrc`` is not loaded
* Change in the behavior of the default predictor with binary analysis. The pattern ``libgpm`` is use, assuming when ``gpm`` is used the program is not threadable. This change solves issues with programs as ``links``.
* Error messages added to the ``source`` command if it is used with a language
that is not xonsh or Python.
**Deprecated:**
* ``xonsh.color_tools.make_pallette()``
Deprecated in release 0.5.10 and will be removed in release 0.6.0.
**Fixed:**
* Now f-strings can be used inside @() without explicit enclosing command in ![]
* Fix for ``x, y, *z = ...`` unpacking.
* Git branch detection now correctly passes the environment down to the subprocess
call. This allows for branch detection when git is installed into a non-standard
location.
* Escape regex characters in ``path_complete`` to avoid regex parsing errors for
certain combinations of characters in path completer
* gistatus: Fixed hash not being shown when in detaced HEAD and there are no tags
* Fix branch colorization when ``git`` or ``hg`` are aliases.
* Fixed leftover ``.git/index.lock`` in ``gitstatus``
* Made JSON history loading more robust to corrupt files.
* Starting a new command with an open parentheses will no longer
throw a traceback when ``$UPDATE_COMPLETIONS_ON_KEYPRESS`` is
``True``.
* Automatically wrapping subprocess calls would sometimes include
semincolons and other line-ending tokens, rather than stopping at them.
This has been fixed.
* Numerous spelling errors in documentation, docstrings/comments, text
strings and local variable names.
* Spelling error in the ``xonsh.color_tools.make_pallete()`` public
function declaration. This was fixed by renaming the function to
``xonsh.color_tools.make_palette()`` while maintaining a binding
of ``make_pallete()`` to the new ``make_palette()`` in case users
are already used to this API.
* Fixed issue with starting triple quote strings being run as a command.
* Fixed a problem with escaping charet (^) character for cmd.exe in the source-cmd function.
* ``EOF in multi-line statement`` errors were misreported as being on line 0.
Now they are correctly reported as being on the last line of the file.
v0.5.12
====================
**Fixed:**
* Fixed ``release.xsh`` to prevent it from dirtying the repo on release and
leading to an unwanted ``.dev`` suffix on the version number
v0.5.11
====================
**Added:**
* ``release.xsh`` creates a github release with the merged news entries as the
release body
**Fixed:**
* ``xonfig`` now displays the proper value for "on linux"
v0.5.10
====================
**Added:**
* Added ``xclip`` and ``repo`` to default threadable predictors (Issues #2355
and #2348)
* Pretty printing of the $PATH variable
* Add "fzf-widgets" xontrib which provides fuzzy search productivity widgets
with on custom keybindings to xontrib list.
* New ``free_cwd`` xontrib for Windows, which prevent the current directory from being locked when the prompt is shown.
This allows the other programs or Windows explorer to delete the current or parent directory. This is accomplished by
resetting the CWD to the users home directory temporarily while the prompt is displayed. The directory is still locked
while any commands are processed so xonsh still can't remove it own working directory.
**Changed:**
* Codecov threshold to 2%
**Removed:**
* On Windows environments variables in wrapped like``%foo%`` are no longer expanded automatically.
**Fixed:**
* Fixed the ``--rc`` option so it now runs xonsh with the specified rc file
* ``@$`` operator now functions properly when returned command is an alias
* Correct line continuation would not work on Windows if the line continuations were used
in the ``xonshrc`` file.
* Fixed a regression in the Windows ``sudo`` command, that allows users to run elevated commands in xonsh.
* Fix echo command from xoreutils.
* Fixed a bug on Windows which meant xonsh wasn't using PATH environment variable but instead relying on a default
value from the windows registry.
v0.5.9
====================
**Added:**
* Add ``Alt .`` keybinding to ``bashisms-xontrib`` to insert last argument of
previous command into current buffer
**Fixed:**
* Fix crash when openSSH version of bash is on PATH on Windows.
* Added missing ensurers to make sure that ``bool`` env_vars are bools and
``int`` env_vars are integers:
* ``DIRSTACK_SIZE``
* ``EXPAND_ENV_VARS``
* ``PUSHD_MINUS``
* ``PUSHD_SILENT``
* ``SUGGEST_COMMANDS``
* ``SUGGEST_MAX_NUM``
* ``SUGGEST_THRESHOLD``
v0.5.8
====================
**Changed:**
* The ``xonsh.platform.os_environ`` wrapper is now case-insensitive and
case-preserving on Windows.
* The private ``_TeeStd`` class will no longer attempt to write to a
standard buffer after the tee has been 'closed' and the standard
buffer returned to the system.
**Fixed:**
* Fixed a bug on py34 where os.scandir was used by accident.
* Line continuations (``\\``) is subproc mode will no longer consume the
surrounding whitespace.
* Fixed a bug if foreign_shell name was not written in lower case in
the static configuration file ``config.json``
* Fixed a regression on Windows where caused ``which`` reported that the
``PATH`` environment variable could not be found.
* Fixed issue with foregrounding jobs that were started in the background.
* Fixed that ``Ctrl-C`` crashes xonsh after running an invalid command.
* Fixed an potential ``ProcessLookupError`` issue, see #2288.
v0.5.7
====================
**Added:**
* New ``color_tools`` module provides basic color tools for converting
to and from various formats as well as creating palettes from color
strings.
* Redirections may now be used in string and list-of-strings
aliases.
* Subprocess redirection may now forego the whitespace between the
redirection and a file name. For example,
``echo hello world >/dev/null``.
* Add a ``-P`` flag to the ``cd`` function in order to change directory and
following symlinks.
* ``xonfig tutorial`` command to launch the http://xon.sh/tutorial in the
browser.
* ``@(...)`` syntax now supports generators and tuples without parentheses.
* Sourcing foreign shells now have the ``--show`` option, which
lets you see when script will be run, and the ``--dryrun``
option which prevents the source from actually taking place.
Xonsh's foreign shell API also added these keyword arguments.
* Subprocess mode now supports subshells. Place any xonsh
code between two parentheses, e.g. ``(cmd)``, to run
this command in a separate xonsh subprocess.
* Foreign shell aliases now have the ability to take extra arguments,
if needed.
* Xonsh will issue a warning message when the current working
directory has been remove out from under it and not replaced
prior to running the next command.
* Line continuation backslashes are respected on Windows in the PTK shell if
the backspace is is preceded by a space.
* Added ``ponysay`` as a command which will usually not run in a
threaded mode in the commands cache.
* New ``jsonutils`` module available for serializing special
xonsh objects to JSON.
**Changed:**
* The literal tokens ``and`` and ``or`` must be surrounded by
whitespace to delimit subprocess mode. If they do not have
whitespace on both sides in subproc mode, they are considered
to be part of a command argument.
* The ``xontrib`` command is now flagged as unthreadable and will be
run on the main Python thread. This allows xontribs to set signal
handlers and other operations that require the main thread.
* nvim (Neovim) has been flagged as unthreadable
* The interactive prompt will now catch ``SystemExit`` and, instead
of exiting the session, will refresh the prompt. This is the same
process as for keyboard interrupts.
* Xonsh no longer launches the wizard for new users. Instead a welcome screen is
shown which says how to launch the wizard.
* Added Windows ``expanduser()``-like function which prevents
the expansion of ``~`` that are not followed by a path
separator.
* Collecting xonsh history files was reported to have random runtime
OSError failures. This exception is now handled, just in case. The
The exception will still be printed in debug mode.
* ``Shell.stype`` has been renamed to ``Shell.shell_type``.
* The configuration wizard now displays the proper control sequence to leave
the wizard at the to start of the wizard itself. Note that this is Ctrl+D for
readline and Ctrl+C for prompt-toolkit.
* Callable alias proxy functions are now more friendly to
``functools.partial()``.
* ``prompt.vc.get_hg_branch`` now uses ``os.scandir`` to walk up the filetree
looking for a ``.hg`` directory. This results in (generally) faster branch
resolution compared to the subprocess call to ``hg root``.
* Xonsh's script and code caches will are now invalidated whenever the
xonsh version changes for a given Python version.
* Autowrapping of subprocess globs has been improved to cover
more cases that are ambiguous with Python syntax.
* Job control info when foregrounding or backgrounding jobs will now
only be displayed when xonsh is in interactive mode.
* Enabled virtual terminal processing in the prompt-toolkit shell for Windows.
**Fixed:**
* 3rd party pygments styles (like solorized or monokailight) are now
able to be used in xonsh. These styles are dynamically created upon
first use, rather than being lazily loaded by xonsh.
* On Windows, ``os.environ`` is case insensitive. This would potentially
change the case of environment variables set into the environment.
Xonsh now uses ``nt.environ``, the case sensitive counterpart, to avoid
these issues on Windows.
* Fix how ``$PWD`` is managed in order to work with symlinks gracefully
* ``history replay`` no longer barfs on ``style_name`` when setting up the
environment
* ``Shell.shell_type`` is now properly set to the same value as ``$SHELL_TYPE``.
* Fixed ``source-zsh`` to work with zsh v5.2.
* Fixed issue where ``del (x, y)`` would raise a syntax error.
* Certain vim commands issue commands involving subshells,
and this is now supported.
* Null bytes handed to Popen are now automatically escaped prior
to running a subprocess. This prevents Popen from issuing
embedded null byte exceptions.
* Xonsh will no longer crash is the current working directory is
removed out from under it.
* Multiline strings can now be written in subprocess mode.
* PTK completions will now correctly deduplicate autosuggest completions
and display completions values based on the cursor position.
* Fixed bug where trailing backspaces on Windows paths could be interpreted
as line continuations characters. Now line continuation characters must be
preceded by a space on Windows. This only applies to xonsh in interactive
mode to ensure scripts are portable.
* Importing ``*.xsh`` files will now respect the encoding listed in
that file and properly fallback to UTF-8. This behaviour follows
the rules described in PEP 263.
* Wizard is now able to properly serialize environment paths.
v0.5.6
====================
**Added:**
* New core utility function aliases (written in pure Python) are now
available in ``xonsh.xoreutils``. These include: ``cat``, ``echo``,
``pwd``, ``tee``, ``tty``, and ``yes``. These are not enabled by default.
Use the new ``coreutils`` xontrib to load them.
* CircleCI test post codecov run
* The ``trace`` will automatically disable color printing when
stdout is not a TTY or stdout is captured.
* New ``jedi`` xontrib enables jedi-based tab completions when it is loaded.
This supersedes xonsh's default Python-mode completer.
* The lexer has a new ``split()`` method which splits strings
according to xonsh's rules for whitespace and quotes.
* New events for hooking into the Python import process are now available.
You can now provide a handler for:
- ``on_import_pre_find_spec``
- ``on_import_post_find_spec``
- ``on_import_pre_create_module``
- ``on_import_post_create_module``
- ``on_import_pre_exec_module``
- ``on_import_post_exec_module``
**Changed:**
* The prompt toolkit shell's first completion will now be the
current token from the auto-suggestion, if available.
* Sourcing foreign shells will now safely skip applying aliases
with the same name as existing xonsh aliases by default.
This prevents accidentally overwriting important xonsh standard
aliases, such as ``cd``.
**Fixed:**
* Threadable prediction for subprocesses will now consult both the command
as it was typed in and any resolved aliases.
* The first prompt will no longer print in the middle of the line if the user has
already started typing.
* Windows consoles will now automatically enable virtual terminal processing
with the readline shell, if available. This allows the full use of ANSI
escape sequences.
* On the Windows readline shell, the tab-completion suppression prompt will no
longer error out depending on what you press.
* Fixed issue with subprocess mode wrapping not respecting line continuation
backslashes.
* Handle a bug where Bash On Windows causes platform.windows_bash_command()
to raise CalledProcessError.
* Fixed issues pertaining to completing from raw string paths.
This is particularly relevant to Windows, where raw strings
are inserted in path completion.
* Replace deprecated calls to ``time.clock()`` by calls to
``time.perf_counter()``.
* Use ``clock()`` to set the start time of ``_timings`` in non-windows instead
of manually setting it to ``0.0``.
* The ``trace`` utility will now correctly color output and not
print extraneous newlines when called in a script.
* The ``@$(cmd)`` operator now correctly splits strings according to
xonsh semantics, rather than just on whitespace using ``str.split()``.
* The ``mpl`` xontrib has been updated to improve matplotlib
handling. If ``xontrib load mpl`` is run before matplotlib
is imported and xonsh is in interactive mode, matplotlib
will automatically enter interactive mode as well. Additionally,
``pyplot.show()`` is patched in interactive mode to be non-blocking.
If a non-blocking show fails to draw the figure for some reason,
a regular blocking version is called.
* Fixed issues like ``timeit ls`` causing OSError - "Inappropriate ioctl
for device".
* Fixed a potential "OSError: [Errno 22] Invalid argument" to increase job
control stability.
v0.5.5
====================
**Added:**
* New ``--rc`` command line option allows users to specify paths to run control
files from the command line. This includes both xonsh-based and JSON-based
configuration.
* New ``$UPDATE_COMPLETIONS_ON_KEYPRESS`` controls whether or not completions
will automatically display and update while typing. This feature is only
available in the prompt-toolkit shell.
**Changed:**
* Xonsh scripts now report ``__file__`` and ``__name__`` when run as scripts
or sourced. These variables have the same meaning as they do in Python
scripts.
* ``$XONSHRC`` and related configuration variables now accept JSON-based
static configuration file names as elements. This unifies the two methods
of run control to a single entry point and loading system.
* The ``xonsh.shell.Shell()`` class now requires that an Execer instance
be explicitly provided to its init method. This class is no longer
responsible for creating an execer an its dependencies.
* Moved decorators ``unthreadable``, ``uncapturable`` from
``xonsh.proc`` to ``xonsh.tools``.
* Some refactorings on jobs control.
**Deprecated:**
* The ``--config-path`` command line option is now deprecated in favor of
``--rc``.
**Removed:**
* ``xonsh.environ.DEFAULT_XONSHRC`` has been removed due to deprecation.
For this value, please check the environment instead, or call
``xonsh.environ.default_xonshrc(env)``.
**Fixed:**
* Command pipelines that end in a callable alias are now interruptable with
``^C`` and the processes that are piped into the alias have their file handles
closed. This should ensure that the entire pipeline is closed.
* Fixed issue where unthreadable subprocs were not allowed to be
captured with the ``$(cmd)`` operator.
* The ``ProcProxy`` class (unthreadable aliases) was not being executed and would
hang if the alias was capturable. This has been fixed.
* Fixed a ``tcsetattr: Interrupted system call`` issue when run xonsh scripts.
* Fixed issue with ``ValueError`` being thrown from ``inspect.signature()``
when called on C-extension callables in tab completer.
* Fixed issue that ``ls | less`` crashes on Mac.
* Threadable prediction was incorrectly based on the user input command, rather than
the version where aliases have been resolved. This has been corrected.
v0.5.4
====================
**Added:**
* Add alias ``xip`` ("kip") so that xonsh's Python environment (whatever that is) can be modified.
* HistoryEntry, a SimpleNamespace object that represents a command in history.
* ``xonsh.completers.bash_completion`` module
* Added option to report timing information of xonsh startup times. Start xonsh
with the ``--timings`` flag to use the feature.
* The Python tab completer will now complete the argument names of functions
and other callables.
* Uptime module added to ``xonsh.xoreutils``. This can report the system
boot time and up time.
* The environment variable ``XONSH_HISTORY_BACKEND`` now also supports a
value of class type or a History Backend instance.
* ``on_envvar_new`` event that fires after a new envvar is created.
* ``on_envvar_change`` event that fires after an envvar is changed.
**Changed:**
* history indexing api to be more simple, now returns HistoryEntry.
* Decoupled ``bash_completion`` from xonsh project and added shim back to
xonsh.
* The JSON history backend will now unlock history files that were created
prior to the last reboot.
**Fixed:**
* Fixed broken bash completions on Windows if 'Windows Subsystem for Linux' is installed.
* Readline history would try to read the first element of history prior to
actually loading any history. This caused an exception to be raised on
Windows at xonsh startup when using pyreadline.
* Fixed issue with readline tab completer overwriting initial prefix in
some instances.
* Fixed issue wherein if ``git`` or (presumably) ``hg`` are aliased, then branch
information no longer appears in the ``$PROMPT``
* Fixed an issue with commands that background themselves (such as
``gpg-connect-agent``) not being able to be run from within xonshrc.
v0.5.3
====================
**Added:**
* Tab completion xontrib for python applications based on click framework.
* Added ``on_transform_command`` event for pre-processing that macros can't handle.
* Autodetection of backgroundability by binary analysis on POSIX.
* New argument ``expand_user=True`` to ``tools.expand_path``.
* New ``$COMPLETION_QUERY_LIMIT`` environment variable for setting the
number of completions above which the user will be asked if they wish to
see the potential completions.
* Users may now redirect stdout to stderr in subprocess mode.
**Changed:**
* The ``Block`` and ``Functor`` context managers from ``xonsh.contexts`` have been
rewritten to use xonsh's macro capabilities. You must now enter these via the
``with!`` statement, e.g. ``with! Block(): pass``.
* The ``distributed`` xontrib now needs to use the ``with!`` statement, since it
relies on ``Functor``.
* ``telnet`` has been flagged as unthreadable.
* When ``$DYNAMIC_CWD_ELISION_CHAR`` is non empty and the last dir of cwd is too
long and shortened, the elision char is added at the end.
* ``pygments`` is no longer a strict dependency of the ``prompt_toolkit``
backend. If ``pygments`` is not installed, the PTK backend will use the
default ansi color settings from the terminal. Syntax highlighting requires
that ``pygments`` is installed.
* Events are now keyword arguments only
* Restored ``on_precommand`` to its original signature.
* Move ``built_ins.expand_path`` to ``tools.expand_path``.
* Rename ``tools.expandpath`` to ``tools._expandpath``.
* Added ``gvim`` command to unthreadable predictors.
* The ``source`` alias now passes ``$ARGS`` down to file it is sourcing.
**Removed:**
* ``XonshBlockError`` has been removed, since it no longer serves a purpose.
**Fixed:**
* ``PopenThread`` will now re-issue SIGINT to the main thread when it is
received.
* Fixed an issue that using sqlite history backend does not kill unfinished
jobs when quitting xonsh with a second "exit".
* Fixed an issue that xonsh would fail over to external shells when
running .xsh script which raises exceptions.
* Fixed an issue with ``openpty()`` returning non-unix line endings in its buffer.
This was causing git and ssh to fail when xonsh was used as the login shell on the
server. See https://mail.python.org/pipermail/python-list/2013-June/650460.html for
more details.
* Restored the ability to ^Z and ``fg`` processes on posix platforms.
* CommandPipelines were not guaranteed to have been ended when the return code
was requested. This has been fixed.
* Introduce path expansion in ``is_writable_file`` to fix
``$XONSH_TRACEBACK_LOGFILE=~/xonsh.log``.
* Backgrounding a running process (^Z) now restores ECHO mode to the terminal
in cases where the subprocess doesn't properly restore itself. A major instance
of this behaviour is Python's interactive interpreter.
* Readline backend would not ask the user to confirm the printing of completion
options if they numbered above a certain value. Instead they would be dumped to
the screen. This has been fixed.
* Jupyter kernel was no longer properly running subprocess commands.
This has been fixed.
* The filename is applied to the target of the ``source`` alias, providing better
tracebacks.
v0.5.2
====================
**Added:**
* Added ``weechat`` to default predictors
* ``$DYNAMIC_CWD_ELISION_CHAR`` environment variable to control how a shortened
path is displayed.
**Changed:**
* ``_ret_code`` function of ``prompt_ret_code`` xontrib return now ``None`` when
return code is 0 instead of empty string allowing more customization of prompt
format.
**Fixed:**
* Minor Python completer token counting bug fix.
* multiline syntax error in PTK shell due to buffer not being reset
* Segfaults and other early exit signals are now reported correctly,
again.
* ``tests/bin/{cat,pwd,wc}`` shebang changed to python3
v0.5.1
====================
**Fixed:**
* Fixed xonfig raising error when xonsh is not installed from source.
v0.5.0
====================
**Added:**

* xontrib-mpl now supports iTerm2 inline image display if iterm2_tools python package is installed
* Xonsh now will fallback to other shells if encountered errors when
starting up.
* Added entry to customization faq re: ``dirs`` alias (#1452)
* Added entry to customization faq re: tab completion selection (#1725)
* Added entry to customization faq re: libgcc core dump (#1160)
* Section about quoting in the tutorial.
* The ``$VC_HG_SHOW_BRANCH`` environment variable to control whether to hide the hg branch in the prompt.
* xonfig now contains the latest git commit date if xonsh installed
from source.
* Alt+Enter will execute a multiline code block irrespective of cursor position
* Windows now has the ability to read output asynchronously from
the console.
* Use `doctr <https://drdoctr.github.io/doctr/>`_ to deploy dev docs to github pages
* New ``xonsh.proc.uncapturable()`` decorator for declaring that function
aliases should not be run in a captured subprocess.
* New history backend sqlite.
* Prompt user to install xontrib package if they try to load an uninstalled
xontrib
* Callable aliases may now take a final ``spec`` argument, which is the
corresponding ``SubprocSpec`` instance.
* New ``bashisms`` xontrib provides additional Bash-like syntax, such as ``!!``.
This xontrib only affects the command line, and not xonsh scripts.
* Tests that create testing repos (git, hg)
* New subprocess specification class ``SubprocSpec`` is used for specifying
and manipulating subprocess classes prior to execution.
* New ``PopenThread`` class runs subprocesses on a a separate thread.
* New ``CommandPipeline`` and ``HiddenCommandPipeline`` classes manage the
execution of a pipeline of commands via the execution of the last command
in the pipeline. Instances may be iterated and stream lines from the
stdout buffer. These pipelines read from the stdout & stderr streams in a
non-blocking manner.
* ``$XONSH_STORE_STDOUT`` is now available on all platforms!
* The ``CommandsCache`` now has the ability to predict whether or not a
command must be run in the foreground using ``Popen`` or may use a
background thread and can use ``PopenThread``.
* Callable aliases may now use the full gamut of functions signatures:
``f()``, ``f(args)``, ``f(args, stdin=None)``,
``f(args, stdin=None, stdout=None)``, and `
``f(args, stdin=None, stdout=None, stderr=None)``.
* Uncaptured subprocesses now receive a PTY file handle for stdout and
stderr.
* New ``$XONSH_PROC_FREQUENCY`` environment variable that specifies how long
loops in the subprocess framework should sleep. This may be adjusted from
its default value to improved performance and mitigate "leaky" pipes on
slower machines.
* ``Shift+Tab`` moves backwards in completion dropdown in prompt_toolkit
* PromptFormatter class that holds all the related prompt methods
* PromptFormatter caching when building the prompt
* p-strings: ``p'/foo/bar'`` is short for ``pathlib.Path('/foo/bar')``
* byte strings: prefixes other than ``b'foo'`` (eg, ``RB'foo'``) now work
* Backticks for regex or glob searches now support an additional modifier
``p``, which causes them to return Path objects instead of strings.
* New ``BOTTOM_TOOLBAR`` environment variable to control a bottom toolbar as specified in prompt-toolkit
* New ``$XONSH_STDERR_PREFIX`` and ``$XONSH_STDERR_POSTFIX`` environment
variables allow the user to print a prompt-like string before and after
all stderr that is seen. For example, say that you would like stderr
to appear on a red background, you might set
``$XONSH_STDERR_PREFIX = "{BACKGROUND_RED}"`` and
``$XONSH_STDERR_PREFIX = "{NO_COLOR}"``.
* New ``xonsh.pyghooks.XonshTerminal256Formatter`` class patches
the pygments formatter to understand xonsh color token semantics.
* Load events are now available
* New events added: ``on_post_init``, ``on_pre_cmdloop``, ``on_pre_rc``, ``on_post_rc``, ``on_ptk_create``
* Completion for ``xonsh`` builtin functions ``xontrib`` and ``xonfig``
* Added a general customization FAQ page to the docs to collect various
tips/tricks/fixes for common issues/requests
* ``test_single_command`` and ``test_redirect_out_to_file`` tests in ``test_integrations``
* Add note that the target of redirection should be separated by a space.
**Changed:**
* CircleCI now handles flake8 checks
* Travis doesn't allow failures on nightly
* ``get_hg_branch`` runs ``hg root`` to find root dir and check if we're in repo
* The default style will now use the color keywords (#ansired, #ansidarkred)
to set colors that follow the terminal color schemes. Currently, this requires
prompt_toolkit master (>1.0.8) and pygments master (2.2) to work correctly.
* ``vox activate`` now accepts relative directories.
* Updated the effectivity of ``$XONSH_DEBUG`` on debug messages.
* Better documentation on how to get nice colors in Windows' default console
* All custom prompt_toolkit key binding filters now declared with the
``@Condition`` decorator
* The style for the prompt toolkit completion menu is now lightgray/darkgray instead of turquoise/teal
* landscape.io linting now ignores ply directory
* ``history`` help messages to reflect subcommand usage
* Quote all paths when completion if any of the paths needs be quoted,
so that bash can automatically complete to the max prefix of the paths.
* Tee'd reads now occur in 1kb chunks, rather than character-by-character.
* The ``which`` alias no longer has a trailing newline if it is captured.
This means that ``$(which cmd)`` will simply be the path to the command.
* The following commands are, by default, predicted to be not threadable
in some circumstances:
* bash
* csh
* clear
* clear.exe
* cls
* cmd
* ex
* fish
* htop
* ksh
* less
* man
* more
* mutt
* nano
* psql
* ranger
* rview
* rvim
* scp
* sh
* ssh
* startx
* sudo
* tcsh
* top
* vi
* view
* vim
* vimpager
* xo
* xonsh
* zsh
* The ``run_subproc()`` function has been replaced with a new implementation.
* Piping between processes now uses OS pipes.
* ``$XONSH_STORE_STDIN`` now uses ``os.pread()`` rather than ``tee`` and a new
file.
* The implementation of the ``foreground()`` decorator has been moved to
``unthreadable()``.
* ``voxapi.Vox`` now supports ``pathlib.Path`` and ``PathLike`` objects as virtual environment identifiers
* Renamed FORMATTER_DICT to PROMPT_FIELDS
* BaseShell instantiates PromptFormatter
* readline/ptk shells use PromptFormatter
* Updated the bundled version of ``ply`` to current master available
* vended ``ply`` is now a git subtree to help with any future updates
* ``WHITE`` color keyword now means lightgray and ``INTENSE_WHITE`` completely white
* Removed ``add_to_shell`` doc section from ``*nix`` install pages and instead
relocated it to the general customization page
* Moved a few ``*nix`` customization tips from the linux install page to the general
customization page
**Removed:**
* coverage checks
* ``CompletedCommand`` and ``HiddenCompletedCommand`` classes have been removed
in favor of ``CommandPipeline`` and ``HiddenCommandPipeline``.
* ``SimpleProcProxy`` and ``SimpleForegroundProcProxy`` have been removed
in favor of a more general mechanism for dispatching callable aliases
implemented in the ``ProcProxyThread`` and ``ProcProxy`` classes.
* ``test_run_subproc.py`` in favor of ``test_integrations.py``
* Unused imports in many tests
* Many duplicated tests (copypasta)
**Fixed:**
* xontrib-mpl now preserves the figure and does not permanently alter it for viewing
* Fix up small pep8 violations
* Fixed a bug where some files are not showing using bash completer
* Fixed some issues with subprocess capturing aliases that it probably
shouldn't.
* ``safe_readable()`` now checks for ``ValueError`` as well.
* The scroll bars in the PTK completions menus are back.
* Jupyter kernel installation now respects the setuptools ``root`` parameter.
* Fix ``__repr__`` and ``__str__`` methods of ``SubprocSpec`` so they report
correctly
* Fixed the message printed when which is unable to find the command.
* Fixed a handful of sphinx errors and warnings in the docs
* Fixed many PEP8 violations that had gone unnoticed
* Fix failure to detect an Anaconda python distribution if the python was install from the conda-forge channel.
* current_branch will try and locate the vc binary once
* May now Crtl-C out of an infinite loop with a subprocess, such as
```while True: sleep 1``.
* Fix for stdin redirects.
* Backgrounding works with ``$XONSH_STORE_STDOUT``
* ``PopenThread`` blocks its thread from finishing until command has completed
or process is suspended.
* Added a minimum time buffer time for command pipelines to check for
if previous commands have executed successfully. This is helpful
for pipelines where the last command takes a long time to start up,
such as GNU Parallel. This also checks to make sure that output has occurred.
This includes piping 2+ commands together and pipelines that end in
unthreadable commands.
* ``curr_branch`` reports correctly when ``git config status.short true`` is used
* ``pip`` completion now filters results by prefix
* Fixed streaming ``!(alias)`` repr evaluation where bytes where not
streamed.
* Aliases that begin with a comma now complete correctly (no spurious comma)
* Use ``python3`` in shebang lines for compatibility with distros that still use Python 2 as the default Python
* STDOUT is only stored when ``$XONSH_STORE_STDOUT=True``
* Fixed issue with alias redirections to files throwing an OSError because
the function ProcProxies were not being waited upon.
* Fixed issue with callable aliases that happen to call sys.exit() or
raise SystemExit taking out the whole xonsh process.
* Safely flushes file handles on threaded buffers.
* Proper default value and documentation for ``$BASH_COMPLETIONS``
* Fixed readline completer issues on paths with spaces
* Fix bug in ``argvquote()`` functions used when sourcing batch files on Windows. The bug meant an extra backslash was added to UNC paths.
Thanks to @bytesemantics for spotting it, and @janschulz for fixing the issue.
* pep8, lint and refactor in pytest style of ``test_ptk_multiline.py``, ``test_replay.py``
* Tab completion of aliases returned a upper cased alias on Windows.
* History show all action now also include current session items.
* ``proc.stream_stderr`` now handles stderr that doesn't have buffer attribute
* Made ``history show`` result sorted.
* Fixed issue that ``history gc`` does not delete empty history files.
* Standard stream tees have been fixed to accept the possibility that
they may not be backed by a binary buffer. This includes the pipeline
stdout tee as well as the shell tees.
* Fixed a bug when the pygments plugin was used by third party editors etc.
* CPU usage of ``PopenThread`` and ``CommandPipeline`` has been brought
down significantly.

* Added ``on_precommand`` and ``on_postcommand`` `events </events.html>`_
* New ``FORMATTER_DICT`` entry ``gitstatus`` to provides informative git status
* FOREIGN_ALIASES_OVERRIDE envvar to control whether foreign aliases should
override xonsh aliases with the same name.
* Warning on tutorial about foreign aliases being ignored if a xonsh alias
exist with the same name if not FOREIGN_ALIASES_OVERRIDE.
* The prompt-toolkit shell now auto-inserts matching parentheses, brackets, and quotes. Enabled via the ``XONSH_AUTOPAIR`` environment variable
* Better syntax highlights in prompt-toolkit, including valid command / path highlighting, macro syntax highlighting, and more
* More info on tutorial about history interaction
* Entry on bash_to_xsh
* Macro context managers are now available via the ``with!``
syntax.
**Changed:**
* Devguide reflects the current process of releasing through ``release.xsh``
* moved ``which`` from ``xonsh.aliases`` into ``xoreutils.which``
* ``xonsh.prompt.gitstatus.gitstatus`` now returns a namedtuple
* implementation of ``xonsh.prompt.vc_branch.get_git_branch`` and
``xonsh.prompt.vc_branch.git_dirty_working_directory`` to use 'git status --procelain'
* moved prompt formatting specific functions from ``xonsh.environ``
to ``xonsh.prompt.base``
* All prompt formatter functions moved to ``xonsh.prompt`` subpackage
* Printing the message about foreign aliases being ignored happens only
if XONSH_DEBUG is set.
* Use ``SetConsoleTitleW()`` on Windows instead of a process call.
* Tutorial to reflect the current history command argument functionality
* Macro function arguments now default to ``str``, rather than ``eval``,
for consistency with other parts of the macro system.
**Removed:**
* aliases that use '!' in their name cause they clash with the macro syntax
**Fixed:**
* Fix regression where bash git completions where not loaded
automatically when GitForWindows is installed.
* More tokens are now supported in subproc args, such as ``==``.
* Python completions now work without space delimiters, e.g. ``a=matpl<TAB>``
will complete to ``a=matplotlib``
* Parser would fail on nested, captured suprocess macros. Now, it works,
hooray!?
* now fires chdir event if OS change in working directory is detected.
* ``xonsh.prompt.vc_branch.git_dirty_working_directory``
uses ``porcelain`` option instead of using the bytestring
``nothing to commit`` to find out if a git directory is dirty
* Fix bug where know commands where not highlighted on windows.
* Fixed completer showing executable in upper case on windows.
* Fixed issue where tilde expansion was occurring more than once before an
equals sign.
* test_dirstack test_cdpath_expansion leaving stray testing dirs
* Better completer display for long completions in prompt-toolkit
* Automatically append newline to target of ``source`` alias, so that it may
be exec'd.

* Completion now works on subcommands after pipe, ``&&``, ``||`` and so on.
* cd . and cd <singleCharacter> now work. Fix indexerror in AUTO_PUSHD case, too.
* Fixed issue with accidentally wrapping generators inside of function calls.
* History indexing with string returns most recent command.
v0.4.6
====================
**Added:**
* New option ``COMPLETIONS_CONFIRM``. When set, ``<Enter>`` is used to confirm
completion instead of running command while completion menu is displayed.
* NetBSD is now supported.
* Macro function calls are now available. These use a Rust-like
``f!(arg)`` syntax.
* Macro subprocess call now available with the ``echo! x y z``
syntax.
* A new `event subsystem <http://xon.sh/tutorial_events.html>`_ has been added.
* howto install sections for Debian/Ubuntu and Fedora.
* ``History`` methods ``__iter__`` and ``__getitem__``
* ``tools.get_portions`` that yields parts of an iterable
* Added a py.test plugin to collect ``test_*.xsh`` files and run ``test_*()`` functions.
* ``__repr__`` and ``__str__`` magic method on LazyObject
**Changed:**
* ``create_module`` implementation on XonshImportHook
* Results of the ``bash`` tab completer are now properly escaped (quoted) when necessary.
* Foreign aliases that match xonsh builtin aliases are now ignored with a warning.
* ``prompt_toolkit`` completions now only show the rightmost portion
of a given completion in the dropdown
* The value of ``'none'`` is no longer allowed for ``$SHELL_TYPE`` just during the initial
load from the environment. ``-D``, later times, and other sources still work.
* ``yacc_debug=True`` now load the parser on the same thread that the
Parser instance is created. ``setup.py`` now uses this synchronous
form as it was causing the parser table to be missed by some package
managers.
* Tilde expansion for the home directory now has the same semantics as Bash.
Previously it only matched leading tildes.
* Context sensitive AST transformation now checks that all names in an
expression are in scope. If they are, then Python mode is retained. However,
if even one is missing, subprocess wrapping is attempted. Previously, only the
left-most name was examined for being within scope.
* ``dirstack.pushd`` and ``dirstack.popd`` now handle UNC paths (of form ``\\<server>\<share>\...``), but only on Windows.
They emulate behavior of `CMD.EXE` by creating a temporary mapped drive letter (starting from z: down) to replace
the ``\\<server>\<share>`` portion of the path, on the ``pushd`` and unmapping the drive letter when all references
to it are popped.
* And ``dirstack`` suppresses this temporary drive mapping funky jive if registry entry
``HKCU\software\microsoft\command processor\DisableUNCCheck`` (or HKLM\...) is a DWORD value 1. This allows Xonsh
to show the actual UNC path in your prompt string and *also* allows subprocess commands invoking `CMD.EXE` to run in
the expected working directory. See https://support.microsoft.com/en-us/kb/156276 to satisfy any lingering curiosity.
* ``lazy_locate_binary`` handles binary on different drive letter than current working directory (on Windows).
* ``_curr_session_parser`` now iterates over ``History``
* New implementation of bash completer with better performance and compatibility.
* ``$COMPLETIONS_BRACKETS`` is now available to determine whether or not to
include opening brackets in Python completions
* ``xonsh.bat`` tries to use `pylauncher <https://www.python.org/dev/peps/pep-0397/>`_ when available.
**Removed:**
* ``History`` method ``show``
* ``_hist_get_portion`` in favor of ``tools.get_portions``
* Unused imports in proc, flake8.
**Fixed:**
* xonsh modules imported now have the __file__ attribute
* Context sensitive AST transformer was not adding argument names to the
local scope. This would then enable extraneous subprocess mode wrapping
for expressions whose leftmost name was function argument. This has been
fixed by properly adding the argument names to the scope.
* Foreign shell functions that are mapped to empty filenames no longer
receive aliases since they can't be found to source later.
* Correctly preserve arguments given to xon.sh, in case there are quoted ones.
* Environment variables in subprocess mode were not being expanded
unless they were in a sting. They are now expanded properly.
* Fixed a bug that prevented xonsh from running scripts with code caching disabled.
* Text of instructions to download missing program now does not get off and
appears in whole.
* Fix some test problems when win_unicode_console was installed on windows.
* Fixed bug that prompt string and ``$PWD`` failed to track change in actual working directory if the
invoked Python function happened to change it (e.g via ```os.chdir()```. Fix is to update ``$PWD``
after each command in ```BaseShell.default()```.
* The interactive prompt now correctly handles multiline strings.
* ``cd \\<server>\<share>`` now works when $AUTO_PUSHD is set, either creating a temporary mapped drive or simply
setting UNC working directory based on registry ``DisableUNCCheck``. However, if $AUTO_PUSHD is not set and UNC
checking is enabled (default for Windows), it issues an error message and fails. This improves on prior behavior,
which would fail to change the current working directory, but would set $PWD and prompt string to the UNC path,
creating false expectations.
* fix parsing for tuple of tuples (like `(),()`)
* ``sys.stdin``, ``sys.stdout``, ``sys.stderr`` no longer complete with
opening square brackets
* xonsh now properly handles syntax error messages arising from using values in inappropriate contexts (e.g., ``del 7``).
Changelog:
This is a terse description of the new features added to bash-5.0 since
the release of bash-4.4. As always, the manual page (doc/bash.1) is
the place to look for complete descriptions.
1. New Features in Bash
a. The `wait' builtin can now wait for the last process substitution created.
b. There is an EPOCHSECONDS variable, which expands to the time in seconds
since the Unix epoch.
c. There is an EPOCHREALTIME variable, which expands to the time in seconds
since the Unix epoch with microsecond granularity.
d. New loadable builtins: rm, stat, fdflags.
e. BASH_ARGV0: a new variable that expands to $0 and sets $0 on assignment.
f. When supplied a numeric argument, the shell-expand-line bindable readline
command does not perform quote removal and suppresses command and process
substitution.
g. `history -d' understands negative arguments: negative arguments offset from
the end of the history list.
h. The `name' argument to the `coproc' reserved word now undergoes word
expansion, so unique coprocs can be created in loops.
i. A nameref name resolution loop in a function now resolves to a variable by
that name in the global scope.
j. The `wait' builtin now has a `-f' option, which signfies to wait until the
specified job or process terminates, instead of waiting until it changes
state.
k. There is a define in config-top.h that allows the shell to use a static
value for $PATH, overriding whatever is in the environment at startup, for
use by the restricted shell.
l. Process substitution does not inherit the `v' option, like command
substitution.
m. If a non-interactive shell with job control enabled detects that a foreground
job died due to SIGINT, it acts as if it received the SIGINT.
n. The SIGCHLD trap is run once for each exiting child process even if job
control is not enabled when the shell is in Posix mode.
o. A new shopt option: localvar_inherit; if set, a local variable inherits the
value of a variable with the same name at the nearest preceding scope.
p. `bind -r' now checks whether a key sequence is bound before binding it to
NULL, to avoid creating keymaps for a multi-key sequence.
q. A numeric argument to the line editing `operate-and-get-next' command
specifies which history entry to use.
r. The positional parameters are now assigned before running the shell startup
files, so startup files can use $@.
s. There is a compile-time option that forces the shell to disable the check
for an inherited OLDPWD being a directory.
t. The `history' builtin can now delete ranges of history entries using
`-d start-end'.
u. The `vi-edit-and-execute-command' bindable readline command now puts readline
back in vi insertion mode after executing commands from the edited file.
v. The command completion code now matches aliases and shell function names
case-insensitively if the readline completion-ignore-case variable is set.
w. There is a new `assoc_expand_once' shell option that attempts to expand
associative array subscripts only once.
x. The shell only sets up BASH_ARGV and BASH_ARGC at startup if extended
debugging mode is active. The old behavior of unconditionally setting them
is available as part of the shell compatibility options.
y. The `umask' builtin now allows modes and masks greater than octal 777.
z. The `times' builtin now honors the current locale when printing a decimal
point.
aa. There is a new (disabled by default, undocumented) shell option to enable
and disable sending history to syslog at runtime.
bb. Bash no longer allows variable assignments preceding a special builtin that
changes variable attributes to propagate back to the calling environment
unless the compatibility level is 44 or lower.
cc. You can set the default value for $HISTSIZE at build time in config-top.h.
dd. The `complete' builtin now accepts a -I option that applies the completion
to the initial word on the line.
ee. The internal bash malloc now uses mmap (if available) to satisfy requests
greater than 128K bytes, so free can use mfree to return the pages to the
kernel.
ff. The shell doesn't automatically set BASH_ARGC and BASH_ARGV at startup
unless it's in debugging mode, as the documentation has always said, but
will dynamically create them if a script references them at the top level
without having enabled debugging mode.
gg. The localvar_inherit option will not attempt to inherit a value from a
variable of an incompatible type (indexed vs. associative arrays, for
example).
hh. The `globasciiranges' option is now enabled by default; it can be set to
off by default at configuration time.
ii. Associative and indexed arrays now allow subscripts consisting solely of
whitespace.
jj. `checkwinsize' is now enabled by default.
kk. The `localvar_unset' shopt option is now visible and documented.
ll. The `progcomp_alias' shopt option is now visible and documented.
mm. The signal name processing code now understands `SIGRTMIN+n' all the way
up to SIGRTMAX.
nn. There is a new `seq' loadable builtin.
oo. Trap execution now honors the (internal) max invocations of `eval', since
traps are supposed to be executed as if using `eval'.
pp. The $_ variable doesn't change when the shell executes a command that forks.
qq. The `kill' builtin now supports -sSIGNAME and -nSIGNUM, even though
conforming applications aren't supposed to use them.
rr. POSIX mode now enables the `shift_verbose' option.
2. New Features in Readline
a. Non-incremental vi-mode search (`N', `n') can search for a shell pattern, as
Posix specifies (uses fnmatch(3) if available).
b. There are new `next-screen-line' and `previous-screen-line' bindable
commands, which move the cursor to the same column in the next, or previous,
physical line, respectively.
c. There are default key bindings for control-arrow-key key combinations.
d. A negative argument (-N) to `quoted-insert' means to insert the next N
characters using quoted-insert.
e. New public function: rl_check_signals(), which allows applications to
respond to signals that readline catches while waiting for input using
a custom read function.
f. There is new support for conditionally testing the readline version in an
inputrc file, with a full set of arithmetic comparison operators available.
g. There is a simple variable comparison facility available for use within an
inputrc file. Allowable operators are equality and inequality; string
variables may be compared to a value; boolean variables must be compared to
either `on' or `off'; variable names are separated from the operator by
whitespace.
h. The history expansion library now understands command and process
substitution and extended globbing and allows them to appear anywhere in a
word.
i. The history library has a new variable that allows applications to set the
initial quoting state, so quoting state can be inherited from a previous
line.
j. Readline now allows application-defined keymap names; there is a new public
function, rl_set_keymap_name(), to do that.
k. The "Insert" keypad key, if available, now puts readline into overwrite
mode.
Packaged for wip by Michael Bäuerle.
The Schily Bourne Shell
The Schily Bourne Shell was derived from the Bourne Shell sources from
OpenSolaris.
The Schily Bourne Shell is actively maintained and enhanced on a regular base.
It can be compiled into three variants:
- The non-POSIX SVr4/OpenSolaris variant (obosh)
- The minimal POSIX compliant variant (pbosh)
- The POSIX compliant extended variant (bosh)
This package contains the second variant.

Upstream changes:
Changes from 5.6.1 to 5.6.2
---------------------------
Fix another SIGTTOU case.
Fix SIGWINCH being ignored when zsh is not in the foreground.
The release tarballs are now compressed using xz(1), whereas previously
both xz(1) and gzip(1) versions were available. If this gets in your way,
give us a shout.
Changelog:
Changes from 5.6 to 5.6.1
-------------------------
Fix packaging issue that broke runhelp.
Fix a regression with pipelines getting backgrounded and emitting SIGTTOU.
Upstream changes:
Changes from 5.5.1-test-2 to 5.6
--------------------------------
CVE-2018-0502: Data from the second line of a #! script file might be passed to
execve(). For example, in the following situation -
.
printf '#!foo\nbar' > baz
./baz
.
the shell might take "bar" rather than "foo" for the argv[0] to be passed to
execve(). [ Reported by Anthony Sottile and Buck Evan. ]
CVE-2018-13259: A shebang line longer than 64 characters would be truncated.
For example, in the following situation:
.
( printf '#!'; repeat 64 printf 'x'; printf 'y' ) > foo
./foo
.
the shell might execute x...x (64 repetitions) rather than x...xy (64 x's,
one y). [ Reported by Daniel Shahaf. ]
Changes from 5.5.1 to 5.5.1-test-2
----------------------------------
Non-stop IEEE 754 arithmetic support - Inf and NaN are now returned
from floating point operations where errors were printed before.
Inf and NaN are also recognised in arithmetic expressions.
In shell patterns, [[:blank:]] now honours the locale instead of
matching exclusively on space and tab, like for the other POSIX
character classes or for extended regular expressions.
Nanosecond precision on file times is supported in the module
zsh/stat.
Performing substitutions during post-patch breaks tools such as mkpatches,
making it very difficult to regenerate correct patches after making changes,
and often leading to substituted string replacements being committed.
## v0.4.3

Changelog:
Changes from %.5 to 5.5.1
-------------------------
Apart from a fix for a configuration problem finding singal names from
(some) recent versions of glibc, there are only minor changes.
Changes from 5.4.2 to 5.5
-------------------------
The effect of the NO_INTERACTIVE_COMMENTS option extends into $(...) and
`...` command substitutions when used on the command line. Previously,
comments were always recognized within command substitutions unless the
comment character "#" was disabled via reset of $histchars.
An alternative assignment syntax for indicating indices for arrays
and keys for associative arrays:
typeset -a array=([1]=first [2]=second)
typeset -A assoc=([key1]=val1 [key2]=val2)
is allowed for compatibility with other shells. In the case of normal
arrays the new syntax can be mixed with the old.
Make a copy of the basename() result, so as to avoid a fortify
abort due to overlapping memcpy() when the result from basename()
is subsequently passed to basename().
Bump PKGREVISION.
Changelog:
Bug-Description:
With certain values for PS1, especially those that wrap onto three or more
lines, readline will miscalculate the number of invisible characters,
leading to crashes and core dumps.
R56c is a bugfix-only release everyone must upgrade to:
- [komh] Remove redundant OS/2-specific code, clean up others
- [komh, tg] Fix drive-qualified (absolute and relative) DOS-style path support
in realpath functionality, partially other places
- [tg] Don't substitute ${ENV:-~/.mkshrc} result again
- [tg] Improve OS/2 $PATH (et al.) handling, drive-relative paths
- [tg] Add MKSH_ENVDIR compile-time option for Jehanne and Plan 9
- [tg] Limit nesting when parsing malformed code (Debian #878947)
- [tg] Update wcwidth data with bugfixed script (still Unicode 10; resulting
values are identical to glibc git master for extant chars)
- [Dr. Werner Fink] Raise some time limits in the testsuite
- [Shamar] Add support for the Jehanne operating system
- [komh] Set stdin to text mode before executing child processes on OS/2
- [komh] Pass arguments via a resonse file if executing a child fails
- [Dr. Werner Fink] Early locale tracking as a compile-time option
- [tg] Fix regressions introduced with new fast character classes
Unsorted entries in PLIST files have generated a pkglint warning for at
least 12 years. Somewhat more recently, pkglint has learned to sort
PLIST files automatically. Since pkglint 5.4.23, the sorting is only
done in obvious, simple cases. These have been applied by running:
pkglint -Cnone,PLIST -Wnone,plist-sort -r -F
pkgsrc changes: add doxygen dependency for building docs.
this is unusual as doxygen is heavy, but fish is meant to
be beginner-friendly shell, so documentation is important.
remove now unneeded patch, that getcwd is called with a size
argument now.
# fish 2.7.1 (released December 23, 2017)
This release of fish fixes an issue where iTerm 2 on macOS would display a warning about paste bracketing being left on when starting a new fish session (#4521).
If you are upgrading from version 2.6.0 or before, please also review the release notes for 2.7.0 and 2.7b1 (included below).

# fish 2.7.0 (released November 23, 2017)
There are no major changes between 2.7b1 and 2.7.0. If you are upgrading from version 2.6.0 or before, please also review the release notes for 2.7b1 (included below).
Xcode builds and macOS packages could not be produced with 2.7b1, but this is fixed in 2.7.0.
--
# fish 2.7b1 (released October 31, 2017)
## Notable improvements
- A new `cdh` (change directory using recent history) command provides a more friendly alternative to prevd/nextd and pushd/popd (#2847).
- A new `argparse` command is available to allow fish script to parse arguments with the same behavior as builtin commands. This also includes the `fish_opt` helper command. (#4190).
- Invalid array indexes are now silently ignored (#826, #4127).
- Improvements to the debugging facility, including a prompt specific to the debugger (`fish_breakpoint_prompt`) and a `status is-breakpoint` subcommand (#1310).
- `string` supports new `lower` and `upper` subcommands, for altering the case of strings (#4080). The case changing is not locale-aware yet.
- `string escape` has a new `--style=xxx` flag where `xxx` can be `script`, `var`, or `url` (#4150), and can be reversed with `string unescape` (#3543).
- History can now be split into sessions with the `fish_history` variable, or not saved to disk at all (#102).
- Read history is now controlled by the `fish_history` variable rather than the `--mode-name` flag (#1504).
- `command` now supports an `--all` flag to report all directories with the command. `which` is no longer a runtime dependency (#2778).
- fish can run commands before starting an interactive session using the new `--init-command`/`-C` options (#4164).
- `set` has a new `--show` option to show lots of information about variables (#4265).
## Other significant changes
- The `COLUMNS` and `LINES` environment variables are now correctly set the first time `fish_prompt` is run (#4141).
- `complete`'s `--no-files` option works as intended (#112).
- `echo -h` now correctly echoes `-h` in line with other shells (#4120).
- The `export` compatibility function now returns zero on success, rather than always returning 1 (#4435).
- Stop converting empty elements in MANPATH to "." (#4158). The behavior being changed was introduced in fish 2.6.0.
- `count -h` and `count --help` now return 1 rather than produce command help output (#4189).
- An attempt to `read` which stops because too much data is available still defines the variables given as parameters (#4180).
- A regression in fish 2.4.0 which prevented `pushd +1` from working has been fixed (#4091).
- A regression in fish 2.6.0 where multiple `read` commands in non-interactive scripts were broken has been fixed (#4206).
- A regression in fish 2.6.0 involving universal variables with side-effects at startup such as `set -U fish_escape_delay_ms 10` has been fixed (#4196).
- Added completions for:
- `as` (#4130)
- `cdh` (#2847)
- `dhcpd` (#4115)
- `ezjail-admin` (#4324)
- Fabric's `fab` (#4153)
- `grub-file` (#4119)
- `grub-install` (#4119)
- `jest` (#4142)
- `kdeconnect-cli`
- `magneto` (#4043, #4108)
- `mdadm` (#4198)
- `passwd` (#4209)
- `pip` and `pipenv` (#4448)
- `s3cmd` (#4332)
- `sbt` (#4347)
- `snap` (#4215)
- Sublime Text 3's `subl` (#4277)
- Lots of improvements to completions.
- Updated Chinese and French translations.
Fish shell-like syntax highlighting for Zsh. This package provides
syntax highlighing for the shell zsh. It enables highlighing of
commands whilst they are typed at a zsh prompt into an interactive
terminal. This helps in reviewing commands before running them,
particularly in catching syntax errors.
zsh-completions aims at gathering/developing new completion scripts
that are not available in Zsh yet. The scripts may be contributed to
the Zsh project when stable enough.
don't mess with the declaration of tparm_solaris_kludge unnecessarily.

solaris curses), but I'm not sure how to correct it.

bump PKGREVISION
pkgsrc changes:
- Use PRINT_PLIST_AWK to aid future upgrades.
- Support the "static" option on Darwin and SunOS.
Upstream changes from 5.3.1 to 5.4:
The 'exec' and 'command' precommand modifiers, and options to them, are
now parsed after parameter expansion. Previously, both the modifier and
any options to it were parsed between alias expansion and parameter
expansion (see zshexpn(1)), so they could neither be quoted nor be the
result of parameter expansion. Examples: 's=command; $s -V ls' and
'\command -V ls' now work as expected.
Functions executed by ZLE widgets no longer have their standard input
closed, but redirected from /dev/null instead. That still guards
against user defined widgets inadvertently reading from the tty device.
There is an option WARN_NESTED_VAR, a companion to the existing
WARN_CREATE_GLOBAL that causes a warning if a function updates a
variable from an enclosing scope without using typeset -g. It can be
turned on for an individual function with "functions -W".
zmodload now has an option -s to be silent on a failure to find a module
but still print other errors.
R56b is a bugfix-only release everyone should upgrade to:
- [tg] Reference the FAQ webpage
- [panpo, Riviera] Fix documentation bug wrt. Esc+Ctrl-L
- [tg, Larry Hynes] Fix '0' movement in vi mode
- [tg] Replace broken libcs' offsetof macro with MirBSD's
R56 is a bugfix release with some experimental fixes:
- [tg, Seb] Do not apply alias name restrictions to hash/tilde tracking
- [tg] Restore '.', ':' and '[' in alias names ('[[' is still forbidden)
- [tg] Fix accidentally defanged $PATHSEP test
- [tg] On ^C (INTR and QUIT edchars), shove edit line into history
- [iSKUNK, tg] Begin porting to z/OS using EBCDIC encoding, incomplete

the testsuite
- [tg] New test.sh option -U to pass a UTF-8 locale to use in the tests
- [tg] re_format(7) BSD: [[ $x = *[[:\<:]]foo[[:\>:]]* ]]
- [tg, iSKUNK] Use Config in check.pl only if it exists
- [tg] New matching code for bracket expressions, full POSIX (8bit)
- [komh] Exclude FAT/HPFS/NTFS-unsafe tests on OS/2 (and Cygwin/MSYS)
- [tg] Update to Unicode 10.0.0
- [tg, selk] Make readonly idempotent
- [tg, multiplexd] When truncating the persistent history, do not change the
underlying file, do all operations on the locked one; do not stop using the
history at all if it has been truncated
- [tg, J?rg] Turn off UTF-8 mode upon turning on POSIX mode
- [Martijn Dekker, Geoff Clare, many on the Austin list, tg] In POSIX mode,
make the exec builtin force a $PATH search plus execve
- [tg] Fix GCC 7, Coverity Scan warnings
- [tg, Michal Hlavinka] Track background process PIDs even interactive
- [tg] Always expose mksh's hexdump shell function; speed it up by working on
the input in chunks; use character classes to make it EBCDIC safe
- [tg] Revamp dot.mkshrc default editor selection mechanism
The tcsh package Makefile is included directly by the static-tcsh
and standalone-tcsh Makefiles. Modify some of the variables that
really need to be package-specific to be set with ?= in
tcsh/Makefile and document the package Makefiles that directly
include it.
Set PKGREVISION directly in static-tcsh and standalone-tcsh now
that they can have independent PKGREVISION values.
Bump the PKGREVISION of static-tcsh due to the MAINTAINER now
correctly being listed as agc@ due to this change.
Notable fixes and improvements:
- Jobs running in the background can now be removed from the list
of jobs with the new disown builtin, which behaves like the same
command in other shells.
- Command substitutions now have access to the terminal, like in
other shells. This allows tools like fzf to work properly.
- In cases where the operating system does not report the size of
the terminal, the COLUMNS and LINES environment variables are
used; if they are unset, a default of 80x24 is assumed.
- New French and improved German translations.
- fish no longer depends on the which external command.

uninitialized memory.
2015-04-18

license which is used by nunit and is already approved by various
distros.
2015-04-20

Release Notes for fish 2.5.0 (released February 3, 2017)
The Home, End, Insert, Delete, Page Up and Page Down keys work in Vi-style key bindings (#3731).
Platform Changes
Starting with version 2.5, fish requires a more up-to-date version of C++, specifically C++11 (from 2011). This affects some older platforms:
Linux
For users building from source, GCC's g++ 4.8 or later, or LLVM's clang 3.3 or later, are known to work. Older platforms may require a newer compiler installed. Unfortunately, because of the complexity of the toolchain, binary packages are no longer published by the fish-shell developers for the following platforms:
Red Hat Enterprise Linux and CentOS 5 & 6 for 64-bit builds
Ubuntu 12.04 (EoLTS April 2017)
Debian 7 (EoLTS May 2018)
Installing newer version of fish on these systems will require building from source.
OS X SnowLeopard
Starting with version 2.5, fish requires a C++11 standard library on OS X 10.6 ("SnowLeopard"). If this library is not installed, you will see this error: dyld: Library not loaded: /usr/lib/libc++.1.dylib MacPorts is the easiest way to obtain this library. After installing the SnowLeopard MacPorts release from the install page, run: sudo port -v install libcxx Now fish should launch successfully. (Please open an issue if it does not.) This is only necessary on 10.6. OS X 10.7 and later include the required library by default.
Other significant changes
Attempting to exit with running processes in the background produces a warning, then signals them to terminate if a second attempt to exit is made. This brings the behaviour for running background processes into line with stopped processes. (#3497)
random can now have start, stop and step values specified, or the new choice subcommand can be used to pick an argument from a list (#3619).
A new key bindings preset, fish_hybrid_key_bindings, including all the Emacs-style and Vi-style bindings, which behaves like fish_vi_key_bindings in fish 2.3.0 (#3556).
function now returns an error when called with invalid options, rather than defining the function anyway (#3574). This was a regression present in fish 2.3 and 2.4.0.
fish no longer prints a warning when it identifies a running instance of an old version (2.1.0 and earlier). Changes to universal variables may not propagate between these old versions and 2.5b1.
Improved compatiblity with Android (#3585), MSYS/mingw (#2360), Solaris (#3456, #3340)
Like other shells, the test builting now returns an error for numeric operations on invalid integers (#3346, #3581).
complete no longer recognises --authoritative and --unauthoritative options, and they are marked as obsolete.
status accepts subcommands, and should be used like status is-interactive. The old options continue to be supported for the foreseeable future (#3526), although only one subcommand or option can be specified at a time.
Selection mode (used with "begin-selection") no longer selects a character the cursor does not move over (#3684).
List indexes are handled better, and a bit more liberally in some cases (echo $PATH[1 .. 3] is now valid) (#3579).
The fish_mode_prompt function is now simply a stub around fish_default_mode_prompt, which allows the mode prompt to be included more easily in customised prompt functions (#3641).
Notable fixes and improvements
alias, run without options or arguments, lists all defined aliases, and aliases now include a description in the function signature that identifies them.
complete accepts empty strings as descriptions (#3557).
command accepts -q/--quiet in combination with --search (#3591), providing a simple way of checking whether a command exists in scripts.
Abbreviations can now be renamed with abbr --rename OLD_KEY NEW_KEY (#3610).
The command synopses printed by --help options work better with copying and pasting (#2673).
help launches the browser specified by the $fish_help_browser variable if it is set (#3131).
History merging could lose items under certain circumstances and is now fixed (#3496).
The $status variable is now set to 123 when a syntactically invalid command is entered (#3616).
Exiting fish now signals all background processes to terminate, not just stopped jobs (#3497).
A new prompt_hostname function which prints a hostname suitable for use in prompts (#3482).
The __fish_man_page function (bound to Alt-h by default) now tries to recognize subcommands (e.g. git add will now open the "git-add" man page) (#3678).
A new function edit_command_buffer (bound to Alt-e & Alt-v by default) to edit the command buffer in an external editor (#1215, #3627).
set_color now supports italics (--italics), dim (--dim) and reverse (--reverse) modes (#3650).
Filesystems with very slow locking (eg incorrectly-configured NFS) will no longer slow fish down (#685).
Improved completions for apt (#3695), fusermount (#3642), make (#3628), netctl-auto (#3378), nmcli (#3648), pygmentize (#3378), and tar (#3719).

Release Notes for fish 2.4.0 (released November 8, 2016)
Significant changes
The clipboard integration has been revamped with explicit bindings. The killring commands no longer copy from, or paste to, the X11 clipboard - use the new copy (C-x) and paste (C-v) bindings instead. The clipboard is now available on OS X as well as systems using X11 (e.g. Linux). (#3061)
history uses subcommands (history delete) rather than options (history --delete) for its actions (#3367). You can no longer specify multiple actions via flags (e.g., history --delete --save something).
New history options have been added, including --max=n to limit the number of history entries, --show-time option to show timestamps (#3175, #3244), and --null to null terminate history entries in the search output.
history search is now case-insensitive by default (which also affects history delete) (#3236).
history delete now correctly handles multiline commands (#31).
Vi-style bindings no longer include all of the default emacs-style bindings; instead, they share some definitions (#3068).
If there is no locale set in the environment, various known system configuration files will be checked for a default. If no locale can be found, en_US-UTF.8 will be used (#277).
A number followed by a caret (e.g. 5^) is no longer treated as a redirection (#1873).
The $version special variable can be overwritten, so that it can be used for other purposes if required.
Notable fixes and improvements
The fish_realpath builtin has been renamed to realpath and made compatible with GNU realpath when run without arguments (#3400). It is used only for systems without a realpath or grealpath utility (#3374).
Improved color handling on terminals/consoles with 8-16 colors, particularly the use of bright named color (#3176, #3260).
fish_indent can now read from files given as arguments, rather than just standard input (#3037).
Fuzzy tab completions behave in a less surprising manner (#3090, #3211).
jobs should only print its header line once (#3127).
Wildcards in redirections are highlighted appropriately (#2789).
Suggestions will be offered more often, like after removing characters (#3069).
history --merge now correctly interleaves items in chronological order (#2312).
Options for fish_indent have been aligned with the other binaries - in particular, -d now means --debug. The --dump option has been renamed to --dump-parse-tree (#3191).
The display of bindings in the Web-based configuration has been greatly improved (#3325), as has the rendering of prompts (#2924).
fish should no longer hang using 100% CPU in the C locale (#3214).
A bug in FreeBSD 11 & 12, Dragonfly BSD & illumos prevented fish from working correctly on these platforms under UTF-8 locales; fish now avoids the buggy behaviour (#3050).
Prompts which show git repository information (via __fish_git_prompt) are faster in large repositories (#3294) and slow filesystems (#3083).
fish 2.3.0 reintroduced a problem where the greeting was printed even when using read; this has been corrected again (#3261).
Vi mode changes the cursor depending on the current mode (#3215).
Command lines with escaped space characters at the end tab-complete correctly (#2447).
Added completions for:
arcanist (#3256)
connmanctl (#3419)
figlet (#3378)
mdbook (#3378)
ninja (#3415)
p4, the Perforce client (#3314)
pygmentize (#3378)
ranger (#3378)
Improved completions for aura (#3297), abbr (#3267), brew (#3309), chown (#3380, #3383),cygport (#3392), git (#3274, #3226, #3225, #3094, #3087, #3035, #3021, #2982, #3230), kill & pkill (#3200), screen (#3271), wget (#3470), and xz (#3378).
Distributors, packagers and developers will notice that the build process produces more succinct output by default; use make V=1 to get verbose output (#3248).
Improved compatibility with minor platforms including musl (#2988), Cygwin (#2993), Android (#3441, #3442), Haiku (#3322) and Solaris.
Automatic cursor changes are now only enabled on the subset of XTerm versions known to support them, resolving a problem where older versions printed garbage to the terminal before and after every prompt (#3499).
Improved the title set in Apple Terminal.app.
Added completions for defaults and improved completions for diskutil (#3478).
Release Notes for fish 2.3.1 (released July 3, 2016)
This is a functionality and bugfix release. This release does not contain all the changes to fish since the last release, but fixes a number of issues directly affecting users at present and includes a small number of new features.
Significant changes
A new fish_key_reader binary for decoding interactive keypresses (#2991).
fish_mode_prompt has been updated to reflect the changes in the way the Vi input mode is set up (#3067), making this more reliable.
fish_config can now properly be launched from the OS X app bundle (#3140).
Notable fixes and improvements
Extra lines were sometimes inserted into the output under Windows (Cygwin and Microsoft Windows Subsystem for Linux) due to TTY timestamps not being updated (#2859).
The string builtin's match mode now handles the combination of -rnv (match, invert and count) correctly (#3098).
Improvements to TTY special character handling (#3064), locale handling (#3124) and terminal environment variable handling (#3060).
Work towards handling the terminal modes for external commands launched from initialisation files (#2980).
Ease the upgrade path from fish 2.2.0 and before by warning users to restart fish if the string builtin is not available (#3057).
type -a now syntax-colorizes function source output.
Added completions for alsamixer, godoc, gofmt, goimports, gorename, lscpu, mkdir, modinfo, netctl-auto, poweroff, termite, udisksctl and xz (#3123).
Improved completions for apt (#3097), aura (#3102),git (#3114), npm (#3158), string and suspend (#3154).

A new string builtin to handle… strings! This builtin will measure, split, search and replace text strings, including using regular expressions. It can also be used to turn lists into plain strings using join. string can be used in place of sed, grep, tr, cut, and awk in many situations. (#2296)
After seeing an escape character wait up to 300ms for an additional character. This is consistent with readline (e.g. bash) and can be configured via the fish_escape_delay_ms variable. This allows using escape as the Meta modifier. (#1356)
Add new directories for vendor functions and configuration snippets (#2498)
A new fish_realpath builtin and associated function to allow the use of realpath even on those platforms that don't ship an appropriate command. (#2932)
Alt-# toggles the current command line between commented and uncommented states, making it easy to save a command in history without executing it.
The fish_vi_mode function is now deprecated in favour of fish_vi_key_bindings
Backward-incompatible changes
Unmatched globs will now cause an error, except when used with for, set or count (#2719, #2394)
and and or will now bind to the closest if or while, allowing compound conditions without begin and end (#1428)
set -ql now searches up to function scope for variables (#2502)
status -f will now behave the same when run as the main script or using source (#2643)
source no longer puts the file name in $argv if no arguments are given (#139)
Other Notable Fixes and Improvements
Fish no longer silences errors in config.fish (#2702)
Move the history file to $XDG_DATA_HOME/fish (or ~/.local/share if it has not been set)
Directory autosuggestions will now descend as far as possible if there is only one child directory (#2531)
Add support for bright colors (#1464)
Allow Ctrl-J (\cj) to be bound separately from Ctrl-M (\cm) (#217)
psub now has a "-s"/"-suffix" option to name the temporary file with that suffix
Enable 24-bit colors on select terminals (#2495)
Support for SVN status in the prompt (#2582)
Mercurial and SVN support have been added to the Classic + Git (now Classic + VCS) prompt (via the new __fish_vcs_prompt function) (#2592)
export now handles variables with a "=" in the value (#2403)
Avoid confusing the terminal line driver with non-printing characters in fish_title(#2453)
New completions for:
alsactl
Archlinux’s asp, makepkg
Atom’s apm (#2390)
entr - the "Event Notify Test Runner" (#2265)
Fedora’s dnf (#2638)
OSX diskutil (#2738)
pkgng (#2395)
pulseaudio’s pacmd and pactl
rmmod (#3007)
rust’s rustc and cargo (#2409)
sysctl (#2214)
systemd’s machinectl (#2158), busctl (#2144), systemd-nspawn, systemd-analyze, localectl, timedatectl
and more
Fish no longer has a function called sgrep, freeing it for user customization (#2245)
A rewrite of the completions for cd, fixing a few bugs (#2299, #2300, #562)
Linux VTs now run in a simplified mode to avoid issues (#2311)
The vi-bindings now inherit from the emacs bindings
Fish will also execute fish_user_key_bindings when in vi-mode
funced will now also check $VISUAL (#2268)
A new suspend function (#2269)
Subcommand completion now works better with split /usr (#2141)
The command-not-found-handler can now be overridden by defining a function called __fish_command_not_found_handler in config.fish (#2331)
A few fixes to the Sorin theme
PWD shortening in the prompt can now be configured via the fish_prompt_pwd_dir_length variable, set to the length per path component (#2473)
fish now ships a skeleton file for /etc/fish/config.fish that only contains some documentation, the included code has been moved to the corresponding file in /usr (#2799)
Release Notes for fish 2.2.0 (released July 12, 2015)
Significant Changes
Abbreviations: the new `abbr` command allows for interactively-expanded abbreviations, allowing quick access to frequently-used commands (#731).
Vi mode: run `fish_vi_mode` to switch fish into the key bindings and prompt familiar to users of the Vi editor (#65).
New inline and interactive pager, which will be familiar to users of zsh (#291).
Underlying architectural changes: the `fishd` universal variable server has been removed as it was a source of many bugs and security problems. Notably, old fish sessions will not be able to communicate universal variable changes with new fish sessions. For best results, restart all running instances of `fish`.
The web-based configuration tool has been redesigned, featuring a prompt theme chooser and other improvements.
New German, Brazilian Portuguese, and Chinese translations.
Backward-incompatible changes
These are kept to a minimum, but either change undocumented features or are too hard to use in their existing forms. These changes may break existing scripts.
`commandline` no longer interprets functions "in reverse", instead behaving as expected (#1567).
The previously-undocumented `CMD_DURATION` variable is now set for all commands and contains the execution time of the last command in milliseconds (#1585). It is no longer exported to other commands (#1896).
`if` / `else` conditional statements now return values consistent with the Single Unix Specification, like other shells (#1443).
A new "top-level" local scope has been added, allowing local variables declared on the commandline to be visible to subsequent commands. (#206)
Other notable fixes and improvements
New documentation design (#1662), which requires a Doxygen version 1.8.7 or newer to build.
Fish now defines a default directory for other packages to provide completions. By default this is `/usr/share/fish/vendor-completions.d`; on systems with `pkgconfig` installed this path is discoverable with `pkg-config --variable completionsdir fish`.
A new parser removes many bugs; all existing syntax should keep working.
New `fish_preexec` and `fish_postexec` events are fired before and after job execution respectively (#1549).
Unmatched wildcards no longer prevent a job from running. Wildcards used interactively will still print an error, but the job will proceed and the wildcard will expand to zero arguments (#1482).
The `.` command is deprecated and the `source` command is preferred (#310).
`bind` supports "bind modes", which allows bindings to be set for a particular named mode, to support the implementation of Vi mode.
A new `export` alias, which behaves like other shells (#1833).
`command` has a new `--search` option to print the name of the disk file that would be executed, like other shells' `command -v` (#1540).
`commandline` has a new `--paging-mode` option to support the new pager.
`complete` has a new `--wraps` option, which allows a command to (recursively) inherit the completions of a wrapped command (#393), and `complete -e` now correctly erases completions (#380).
Completions are now generated from manual pages by default on the first run of fish (#997).
`fish_indent` can now produce colorized (`--ansi`) and HTML (`--html`) output (#1827).
`functions --erase` now prevents autoloaded functions from being reloaded in the current session.
`history` has a new `--merge` option, to incorporate history from other sessions into the current session (#825).
`jobs` returns 1 if there are no active jobs (#1484).
`read` has several new options:
`--array` to break input into an array (#1540)
`--null` to break lines on NUL characters rather than newlines (#1694)
`--nchars` to read a specific number of characters (#1616)
`--right-prompt` to display a right-hand-side prompt during interactive read (#1698).
`type` has a new `-q` option to suppress output (#1540 and, like other shells, `type -a` now prints all matches for a command (#261).
Pressing F1 now shows the manual page for the current command (#1063).
`fish_title` functions have access to the arguments of the currently running argument as `$argv[1]` (#1542).
The OS command-not-found handler is used on Arch Linux (#1925), nixOS (#1852), openSUSE and Fedora (#1280).
`Alt`+`.` searches backwards in the token history, mapping to the same behavior as inserting the last argument of the previous command, like other shells (#89).
The `SHLVL` environment variable is incremented correctly (#1634 & #1693).
Added completions for `adb` (#1165 & #1211), `apt` (#2018), `aura` (#1292), `composer` (#1607), `cygport` (#1841), `dropbox` (#1533), `elixir` (#1167), `fossil`, `heroku` (#1790), `iex` (#1167), `kitchen` (#2000), `nix` (#1167), `node`/`npm` (#1566), `opam` (#1615), `setfacl` (#1752), `tmuxinator` (#1863), and `yast2` (#1739).
Improved completions for `brew` (#1090 & #1810), `bundler` (#1779), `cd` (#1135), `emerge` (#1840),`git` (#1680, #1834 & #1951), `man` (#960), `modprobe` (#1124), `pacman` (#1292), `rpm` (#1236), `rsync` (#1872), `scp` (#1145), `ssh` (#1234), `sshfs` (#1268), `systemctl` (#1462, #1950 & #1972), `tmux` (#1853), `vagrant` (#1748), `yum` (#1269), and `zypper` (#1787).
- Get rid of useless Makefile.common and pointless variables since there is
no longer a zsh-current package.
- Remove non-standard per-OS non-checksummed patch file in FILESDIR.
Integrate it correctly in the normal way.
- Ensure our patched configure.ac is actually regenerated.
- Use REPLACE_INTERPRETER instead of homegrown subst replacements.
- Remove esoteric and fragile configuration variables, a bunch of legacy OS
based options, and simply depend correctly on terminfo and curses.
- Remove custom test targets and requirements for root access, the test suite
works fine as a non-root user and can be done in the normal way.
- Use options.mk
- Set maintainer to pkgsrc-users, uebayasi resigned.
Fixes build on at least SunOS. Tested on SunOS, Darwin, NetBSD (with and
without the "static" option), and Linux.

changes:
patch 06:
Out-of-range negative offsets to popd can cause the shell to crash attempting
to free an invalid memory block.
patch 07:
When performing filename completion, bash dequotes the directory name being
completed, which can result in match failures and potential unwanted
expansion.
patch 08:
Under certain circumstances, bash will evaluate arithmetic expressions as
part of reading an expression token even when evaluation is suppressed. This
happens while evaluating a conditional expression and skipping over the
failed branch of the expression.
patch 09:
Depending on compiler optimizations and behavior, the `read' builtin may not
save partial input when a timeout occurs.
patch 10:
Depending on compiler optimizations and behavior, the `read' builtin may not
save partial input when a timeout occurs.
patch 11:
Subshells begun to run command and process substitutions may attempt to
set the terminal's process group to an incorrect value if they receive
a fatal signal. This depends on the behavior of the process that starts
the shell.

Changelog:
Changes from 5.2 to 5.3
-----------------------
It is possible to enable character width support for Unicode 9 by
configuring with `--enable-unicode9'; this compiles in some additional
tables. At some point this support may move into a module, in which
case the configure option will be changed to cause the module to be
permanently loaded. This option is not useful unless your terminal also
supports Unicode 9.
The new word modifier ':P' computes the physical path of the argument.
It is different from the existing ':a' modifier which always resolves
'/before/here/../after' to '/before/after', and differs from the
existing ':A' modifier which resolves symlinks only after 'here/..' is
removed, even when /before/here is itself a symbolic link. It is
recommended to review uses of ':A' and, if appropriate, convert them
to ':P' as soon as compatibility with 5.2 is no longer a requirement.
The output of "typeset -p" uses "export" commands or the "-g" option
for parameters that are not local to the current scope. Previously,
all output was in the form of "typeset" commands, never using "-g".
vi-repeat-change can repeat user-defined widgets if the widget calls
zle -f vichange.
The parameter $registers now makes the contents of vi register buffers
available to user-defined widgets.
New vi-up-case and vi-down-case builtin widgets bound to gU/gu (or U/u
in visual mode) for doing case conversion.
A new select-word-match function provides vim-style text objects with
configurable word boundaries using the existing match-words-by-style
mechanism.
Support for the conditional expression [[ -v var ]] to test if a
variable is set for compatibility with other shells.
The print and printf builtins have a new option -v to assign the output
to a variable. This is for bash compatibility but with the additional
feature that, for an array, a separate element is used each time the
format is reused.
New x: syntax in completion match specifications make it possible to
disable match specifications hardcoded in completion functions.
- Fix type of read in prompt confirmation (eg. rmstar) (David Kaspar)
- Fix out of bounds read (Brooks Davis)
- Don't play pointer tricks that are undefined in modern c (Brooks Davis)
- Use `` instead $() for solaris, bleh.
This is a terse description of the new features added to bash-4.4 since
the release of bash-4.3. As always, the manual page (doc/bash.1) is
the place to look for complete descriptions.
1. New Features in Bash
a. There is now a settable configuration #define that will cause the shell
to exit if the shell is running setuid without the -p option and setuid
to the real uid fails.
b. Command and process substitutions now turn off the `-v' option when
executing, as other shells seem to do.
c. The default value for the `checkhash' shell option may now be set at
compile time with a #define.
d. The `mapfile' builtin now has a -d option to use an arbitrary character
as the record delimiter, and a -t option to strip the delimiter as
supplied with -d.
e. The maximum number of nested recursive calls to `eval' is now settable in
config-top.h; the default is no limit.
f. The `-p' option to declare and similar builtins will display attributes for
named variables even when those variables have not been assigned values
(which are technically unset).
g. The maximum number of nested recursive calls to `source' is now settable
in config-top.h; the default is no limit.
h. All builtin commands recognize the `--help' option and print a usage
summary.
i. Bash does not allow function names containing `/' and `=' to be exported.
j. The `ulimit' builtin has new -k (kqueues) and -P (pseudoterminals) options.
k. The shell now allows `time ; othercommand' to time null commands.
l. There is a new `--enable-function-import' configuration option to allow
importing shell functions from the environment; import is enabled by
default.
m. `printf -v var ""' will now set `var' to the empty string, as if `var=""'
had been executed.
n. GLOBIGNORE, the pattern substitution word expansion, and programmable
completion match filtering now honor the value of the `nocasematch' option.
o. There is a new ${parameter@spec} family of operators to transform the
value of `parameter'.
p. Bash no longer attempts to perform compound assignment if a variable on the
rhs of an assignment statement argument to `declare' has the form of a
compound assignment (e.g., w='(word)' ; declare foo=$w); compound
assignments are accepted if the variable was already declared as an array,
but with a warning.
q. The declare builtin no longer displays array variables using the compound
assignment syntax with quotes; that will generate warnings when re-used as
input, and isn't necessary.
r. Executing the rhs of && and || will no longer cause the shell to fork if
it's not necessary.
s. The `local' builtin takes a new argument: `-', which will cause it to save
and the single-letter shell options and restore their previous values at
function return.
t. `complete' and `compgen' have a new `-o nosort' option, which forces
readline to not sort the completion matches.
u. Bash now allows waiting for the most recent process substitution, since it
appears as $!.
v. The `unset' builtin now unsets a scalar variable if it is subscripted with
a `0', analogous to the ${var[0]} expansion.
w. `set -i' is no longer valid, as in other shells.
x. BASH_SUBSHELL is now updated for process substitution and group commands
in pipelines, and is available with the same value when running any exit
trap.
y. Bash now checks $INSIDE_EMACS as well as $EMACS when deciding whether or
not bash is being run in a GNU Emacs shell window.
z. Bash now treats SIGINT received when running a non-builtin command in a
loop the way it has traditionally treated running a builtin command:
running any trap handler and breaking out of the loop.
aa. New variable: EXECIGNORE; a colon-separate list of patterns that will
cause matching filenames to be ignored when searching for commands.
bb. Aliases whose value ends in a shell metacharacter now expand in a way to
allow them to be `pasted' to the next token, which can potentially change
the meaning of a command (e.g., turning `&' into `&&').
cc. `make install' now installs the example loadable builtins and a set of
bash headers to use when developing new loadable builtins.
dd. `enable -f' now attempts to call functions named BUILTIN_builtin_load when
loading BUILTIN, and BUILTIN_builtin_unload when deleting it. This allows
loadable builtins to run initialization and cleanup code.
ee. There is a new BASH_LOADABLES_PATH variable containing a list of directories
where the `enable -f' command looks for shared objects containing loadable
builtins.
ff. The `complete_fullquote' option to `shopt' changes filename completion to
quote all shell metacharacters in filenames and directory names.
gg. The `kill' builtin now has a `-L' option, equivalent to `-l', for
compatibility with Linux standalone versions of kill.
hh. BASH_COMPAT and FUNCNEST can be inherited and set from the shell's initial
environment.
ii. inherit_errexit: a new `shopt' option that, when set, causes command
substitutions to inherit the -e option. By default, those subshells disable
-e. It's enabled as part of turning on posix mode.
jj. New prompt string: PS0. Expanded and displayed by interactive shells after
reading a complete command but before executing it.
kk. Interactive shells now behave as if SIGTSTP/SIGTTIN/SIGTTOU are set to
SIG_DFL when the shell is started, so they are set to SIG_DFL in child
processes.
ll. Posix-mode shells now allow double quotes to quote the history expansion
character.
mm. OLDPWD can be inherited from the environment if it names a directory.
nn. Shells running as root no longer inherit PS4 from the environment, closing
a security hole involving PS4 expansion performing command substitution.
oo. If executing an implicit `cd' when the `autocd' option is set, bash will
now invoke a function named `cd' if one exists before executing the `cd'
builtin.
pp. Value conversions (arithmetic expansions, case modification, etc.) now
happen when assigning elements of an array using compound assignment.
qq. There is a new option settable in config-top.h that makes multiple
directory arguments to `cd' a fatal error.
rr. Bash now uses mktemp() when creating internal temporary files; it produces
a warning at build time on many Linux systems.
2. New Features in Readline
a. The history truncation code now uses the same error recovery mechansim as
the history writing code, and restores the old version of the history file
on error. The error recovery mechanism handles symlinked history files.
b. There is a new bindable variable, `enable-bracketed-paste', which enables
support for a terminal's bracketed paste mode.
c. The editing mode indicators can now be strings and are user-settable
(new `emacs-mode-string', `vi-cmd-mode-string' and `vi-ins-mode-string'
variables). Mode strings can contain invisible character sequences.
Setting mode strings to null strings restores the defaults.
d. Prompt expansion adds the mode string to the last line of a multi-line
prompt (one with embedded newlines).
e. There is a new bindable variable, `colored-completion-prefix', which, if
set, causes the common prefix of a set of possible completions to be
displayed in color.
f. There is a new bindable command `vi-yank-pop', a vi-mode version of emacs-
mode yank-pop.
g. The redisplay code underwent several efficiency improvements for multibyte
locales.
h. The insert-char function attempts to batch-insert all pending typeahead
that maps to self-insert, as long as it is coming from the terminal.
i. rl_callback_sigcleanup: a new application function that can clean up and
unset any state set by readline's callback mode. Intended to be used
after a signal.
j. If an incremental search string has its last character removed with DEL, the
resulting empty search string no longer matches the previous line.
k. If readline reads a history file that begins with `#' (or the value of
the history comment character) and has enabled history timestamps, the
history entries are assumed to be delimited by timestamps. This allows
multi-line history entries.
l. Readline now throws an error if it parses a key binding without a
terminating `:' or whitespace.
m. The default binding for ^W in vi mode now uses word boundaries specified
by Posix (vi-unix-word-rubout is bindable command name).
n. rl_clear_visible_line: new application-callable function; clears all
screen lines occupied by the current visible readline line.
o. rl_tty_set_echoing: application-callable function that controls whether
or not readline thinks it is echoing terminal output.
p. Handle >| and strings of digits preceding and following redirection
specifications as single tokens when tokenizing the line for history
expansion.
q. Fixed a bug with displaying completions when the prefix display length
is greater than the length of the completions to be displayed.
r. The :p history modifier now applies to the entire line, so any expansion
specifying :p causes the line to be printed instead of expanded.
s. New application-callable function: rl_pending_signal(): returns the signal
number of any signal readline has caught but not yet handled.
t. New application-settable variable: rl_persistent_signal_handlers: if set
to a non-zero value, readline will enable the readline-6.2 signal handler
behavior in callback mode: handlers are installed when
rl_callback_handler_install is called and removed removed when a complete
line has been read.
xonsh is a Python-ish, BASHwards-looking shell language and command prompt. The
language is a superset of Python 3.4+ with additional shell primitives. xonsh
(pronounced conch) is meant for the daily use of experts and novices alike.
(and __EXTENSIONS__ for strict STDC). Also needs -lm.
Fix testing to work prior to [stage-]install. No revbump needed.

Changelog:
Changes that improve compatibility w/ the Sixth Edition (V6) UNIX
Thompson shell are marked w/ a `C:' in the details below.
-------------------------------------------------------------------------------
[osh-current] (development):
* Work In Progress ( see http://v6shell.org/src/current/ )
-------------------------------------------------------------------------------
[osh-20160108] (latest):
README:
* Updated supported systems to include FreeBSD 10.2,
Mac OS X 10.11 (El Capitan), NetBSD 7.0, OpenBSD 5.[78],
and Debian 8.2 (jessie).
Makefile:
* Changed `-W' to `-Wextra' (same warning, newer name). From gcc(1) -
This option used to be called -W. The older name is still supported,
but the newer name is more descriptive.
DEDICATIONS:
* Updated the URL for dmr's home page at Bell Labs.
*.h:
* Added a sh6-related comment to the top of the header files
since they are used by sh6 and its external utilities.
examples/dot.oshrc:
* Redirected diagnostics from leaks(1) (Mac OS X) to /dev/null.
-------------------------------------------------------------------------------
[osh-20150115]:
if.c, osh.c, strtoint.[hc], util.c:
* Changed the strtoint() function to convert string into a
long instead of an int, and ensured that numbers which might
be considered to have an octal form (valid or invalid) are
not treated as if they are decimal integers. For example:
`if 0[0-9] -eq [0-9]' and `if [0-9] -eq 0[0-9]' and similar
are always false, resulting in an error.
if.c, util.c:
* Changed how the built-in & external if(1) commands call
the strtoint() function.
err.h, strtoint.c:
* Changed the "not an integer" diagnostic for the strtoint()
function to "bad integer".
err.h, if.c, util.c:
* Changed the "not a digit" diagnostic for the built-in & external
if(1) commands to "bad digit".
err.h:
* Changed the order of the definitions for diagnostics to make finding
the "... expected" ones for if(1) a bit easier.
-------------------------------------------------------------------------------
[osh-20141024]:
README:
* Added OS X 10.10 (Yosemite) to supported systems.
* Added Debian 7.7 (wheezy) to supported systems.
examples/*.osh.login:
* Changed /usr/X11 to /opt/X11 in *PATH.
examples/dot.oshrc:
* Updated the sh6i alias to make it trap and untrap the 1 (HUP),
2 (INT), 3 (QUIT), 13 (PIPE), 14 (ALRM), 15 (TERM), 18 (TSTP),
21 (TTIN), and 22 (TTOU) signals accordingly for better behavior.
-------------------------------------------------------------------------------
[osh-20140820]:
* See CHANGES6 .
-------------------------------------------------------------------------------
[osh-20140410]:
Makefile:
* Changed MOXARCH to OSXCFLAGS & OSXLDFLAGS to play better w/ MacPorts.
Makefile.config:
* Added comment to celebrate 12 years of osh via osh-current.
osh.1:
* Added missing (+) to version in Special commands.
osh.c:
* Enable `.' and `source' special built-in command execution
to succeed when the user invokes the shell as `osh -c string'.
EG:
% osh -c '. file [arg1 ...]' [arg1 ...]
or:
% osh -c 'source file [arg1 ...]' [arg1 ...]
.
-------------------------------------------------------------------------------
[osh-20131109]:
osh.1:
* Changed `LICENSE' to LICENSE to match the other manual pages.
examples/FILEPREP:
* Changed `sigign' invocation to `trap'.
examples/dot.oshrc:
* Added two useful pwd-related aliases: `ocpwd' and `opwd'
* Added a `now' and a `sysinfo' alias.
-------------------------------------------------------------------------------
[osh-20130331]:
*sh.[ch]:
* Removed the deprecated $n and $s parameters.
Now, the user can `set' and `unset' n and s as shell variables.
The following command line is a simple way to replace
all instances of $n w/ $# and $s w/ $? in file:
% <file(rm -f file;sed 's/$n/$#/g;s/$s/$?/g'>file)
.
osh:
* Added code to print diagnostics w/ line numbers when possible.
When reporting error(s), if a diagnostic is to be printed, the
shell gets the line number of the file where the error happened,
adjusts the diagnostic (adding the name of the file and the line
number if the standard input from which the shell reads and
interprets commands lines is seekable), and prints it. EG:
% echo R* ; osh R* ; head -1 R*
README
osh: README: 1: syntax error
Welcome to Osh (V6Shell) - osh-20130331 !
.
* Renamed the `sigign' special built-in command to `trap'
to make osh signal-trapping behavior more sh-like. Granted,
trap is a misnomer since osh only ignores signals for now.
osh.1:
* Removed the documentation for the $n and $s parameters.
* Changed the documentation for `sigign' to `trap' as needed.
examples/*:
* Made stty(1) invocation conditional in .../etc.osh.login .
* Escaped $1 when setting hcount alias in .../dot.oshrc .
-------------------------------------------------------------------------------
[osh-20120604]:
* New file: Makefile.config (included from Makefile)
* New files: strtoint.[ch] (string to integer converter)
* New files: tests/* (regression test suite for osh/sh6)
Makefile:
* Added a "check" target to run the tests w/ osh and sh6.
* Added a "check-newlog" target to generate new test logs
for the osh and sh6 tests.
defs.h:
* Limited maximum PATHMAX definition to 1024.
pexec.c:
* Changed errno to ENAMETOOLONG for each `path too long' error.
osh:
C: Added missing `Command line overflow' diagnostic.
* Added $# (as a synonym for $n) parameter.
* Added $? (as a synonym for $s) parameter.
* Deprecated $n and $s parameters in favor of $# and $?.
$n and $s parameters will be removed after this release.
* Added simple shell variables. This allows the user to `set' and
`unset' shell variables. For compatibility, these variables are
limited to uppercase and lowercase ASCII alpha names that are
one character in length. For example: $A $B $C and $a $b $c
and so forth.
* Changed quoting to allow $ substitution within double (") quotes.
For example: "$$", "$*", "$1", and so forth. This makes parameter
and variable substitution much more flexible.
* Added `.' as a synonym for `source'.
* Enabled PATH search when opening file for `.' and `source'.
* Changed `setenv' built-in command usage and behavior. Now, name
requires value argument. Updated osh.1 manual page accordingly.
if:
* Added new operators to the built-in `if' command for osh
and to the external `if' command for sh6. Updated the if.1
manual page accordingly. The new operators include: <, >,
-eq, -ne, -gt, -ge, -lt, -le
osh.1:
* Flagged $n and $s parameters as deprecated.
* Added `set' and `unset' documentation to the
"Special commands" subsection.
* Added a new "Variable substitution (+)" subsection.
* Documented `.' as a synonym for `source', and added relevant
PATH search documentation.
* Simplified "SECURITY" section a bit.
* Updated "Quoting" subsection to describe double (") quotes handling.
examples/*:
* Made various changes to reflect current and future osh behavior.
-------------------------------------------------------------------------------
[osh-20120102]:
mkconfig:
* Changed _XOPEN_SOURCE definition from 600 to 600L .
err.h:
* Added DEBUG_ALIAS, DEBUG_GLOB, and DEBUG_PROC definitions
(undefined by default) for printf debugging in osh.c and
util.c if/when needed.
osh.c:
* Changed exit status for alias and unalias so that they exit w/ a
false (1) status when there are no aliases to print, set, or unset.
Otherwise, they exit w/ a true (0) status when there is no error.
* Added 'version' as special built-in command.
osh.1:
* Adjusted $v description in "Parameter substitution" subsection.
* Added version description to "Special commands" subsection.
* Added uname(1) to "SEE ALSO" section.
examples/dot.oshrc:
* Replaced the 'version' alias w/ alias 'v1' 'version'
to invoke the 'version' special built-in command.
-------------------------------------------------------------------------------
[osh-20111129-p1]:
examples/dot.oshrc:
* Re-added missing ';s/ \$//' that git ident removed from version alias.
This removes trailing ' $' as shown in example 1 and 2 below:
% : example 1 ; version
osh-20111129 (NetBSD 5.1 amd64) $
% : example 2 ; version
osh-20111129-p1 (NetBSD 5.1 amd64)
-------------------------------------------------------------------------------
[osh-20111129]:
mkconfig, v.c:
* Added useful build system info from `uname -srm'.
examples/dot.*:
* Removed code to replace osh w/ sh6 when invoked as
`osh [-i | -l] sh6'. Use sh6i alias instead.
* Changed sh6i alias for sake of simplicity.
* Removed sh6l alias.
* Changed from using kill(1) to kill current ssh-agent process
to using ssh-agent(1) and its `-k' flag instead.
* Added handy new v and version aliases. For example:
% v ; : Same as doing % echo $v
osh-20111129
% version
osh-20111129 (NetBSD 5.1 amd64)
-------------------------------------------------------------------------------
[osh-20111027]:
* New file: DEDICATIONS (in memory of Dennis M. Ritchie (dmr))
AUTHORS:
* Added reference to DEDICATIONS file.
LICENSE:
* Added two more OpenBSD license references.
mkconfig:
* Fixed a problem w/ the mkconfig script on OpenBSD, where which(1)
used to send a "newgrp: Command not found." diagnostic to standard
output, not standard error. It looks like the noted OpenBSD which(1)
problem has since been fixed though.
osh:
* Fixed a globbing problem caused by an unsigned-integer overflow.
* Added $# (as a synonym for $n) and $* parameters.
* Added a new, command-aliasing feature.
osh.1:
* Added `alias' and `unalias' documentation to the
"Special commands" subsection.
* Added a new "Aliases (+)" subsection.
* Added a new "Metacharacters" subsection.
*.1:
* Changed the visual style of the manual pages, regarding bold, italic,
and `literal' text. The intent was to make for easier reading.
if:
* Added `:' as if(1) special command. It is useful when debugging
scripts and helps when documenting them.
examples/dot.*:
* Documented by example how to turn alias arguments into a no-op.
* Added ssh-agent support. This allows the same ssh-agent process
to be used for shared ssh key(s) across multiple concurrent
login sessions. It also kills the ssh-agent process on
logout when appropriate.
NEWS:
Changes from 5.1.1 to 5.2
-------------------------
The new module zsh/param/private can be loaded to allow the shell
to define parameters that are private to a function scope (i.e. are
not propagated to nested functions called within this function).
The parameter flag ${(P)...} is now more useful when it appears in
a nested expansion. For example,
typeset -A assoc=(one un two deux three trois)
name=assoc
print ${${(P)name}[one]}
now prints "un". In previous versions of the shell the value of the
substitution was fully expanded on return from ${(P)name}, making
associative array subscripting difficult. As a side effect, flags
for formatting appearing in the inner substitution now affect the
substitution of the name (into "assoc" in this case), which is not
normally useful: flags that should apply to the value must be in the
outer substitution.
The GLOB_STAR_SHORT option allows the pattern **/* to be shortened to
just ** if no / follows. so **.c searches recursively for a file whose
name has the suffix ".c".
The effect of the WARN_CREATE_GLOBAL option has been significantly
extended, so expect it to cause additional warning messages about
parameters created globally within function scope.
README:
Incompatibilities between 5.1 and 5.2
-------------------------------------
The behaviour of the parameter flag (P) has changed when it appears
in a nested parameter group, in order to make it more useful in
such cases. A (P) in the outermost parameter group behaves as
before. See NEWS for more.
Existing SHA1 digests verified, all found to be the same on the

Changelog:
Changes from 5.1 to 5.1.1
-------------------------
5.1.1 is primarily a bug fix release; however, a few minor features were
added.
The ZLE variables YANK_ACTIVE, YANK_START and YANK_END have been added
and are useful for managing highlighting.
The zsh-specific pattern match range tests have been supplemented with
[:INCOMPLETE:] and [:INVALID:] to help detect the state of partially
read multibyte character strings.
their time compiling, and 50% spinning in shell scripts. If you'd rather
spend your power bill on useful gcc cycles though, you might desire to use a
different shell for running build scripts - like pdksh, which is conveniently
available at bootstrap time.
But what if pdksh does this to you?
pdksh -c 'f=`pdksh -c set | wc -l`; f=$((f+1)); while ((f < 100000)); do f=$((f+1)); eval "v_${f}=0"; echo "$f"; done'|tail -1
13106
segmentation fault (core dumped) pdksh -c
Well that's annoying, isn't it.
% echo $(((13106*10+7)/8))
16383
... that's a magical number. Coincidence? Well, no.
tp->nfree = 8*nsize/10; /* table can get 80% full */
This particularly ugly overflow happens because tp->size is a short. When
texpand() does:
p = &ntblp[hash(tblp->name) & (tp->size-1)];
tp->size-1 will, given enough variables (80% of 2^15), type coerce into a
sign-extended 32-bit value of:
info registers $ecx
ecx 0xffff7fff -32769
That hash() function does more or less what you guess, it's a 32 bit unsigned
value. The chances of the final pointer pointing inside the valid allocated
block of memory are very low indeed.
The least-change solution is to change tp->size to a 32 bit value. I've left
it signed because that matches, for example, the size parameter passed to
texpand(). But really this code would be more correct with a liberal
sprinkling of "unsigned", and perhaps a bit of "size_t".
This change allows ffmpeg's configure script, as interpreted by pdksh, to
produce more usable output than a core file.
Bump PKGREVISION for code change.
OmniOS is an Illumos distro which falls under the SunOS variant for us.

zsh-5.1/NEWS:
Changes from 5.0.8 to 5.1
-------------------------
The builtins declare, export, local, readonly and typeset
now have corresponding reserved words. When used in
this form, the builtin syntax is extended so that assignments
following the reserved word are treated similarly to
assignments that appear at the start of the command line.
For example,
local scalar=`echo one word` array=(several words)
creates a local "scalar" containing the text "one word"
and an array "array" containing the words "several"
"words".
- The print builtin has new options -x and -X to expand tabs.
- Several new command completions and numerous updates to others.
- Options to "fc" to segregate internal and shared history.
- All emulations including "sh" use multibyte by default; several
repairs to multibyte handling.
- ZLE supports "bracketed paste" mode to avoid interpreting pasted
newlines as accept-line. Pastes can be highlighted for visibility
and to make it more obvious whether accept-line has occurred.
- Improved (though still not perfect) POSIX compatibility for getopts
builtin when POSIX_BUILTINS is set.
- New setopt APPEND_CREATE for POSIX-compatible NO_CLOBBER behavior.
- Completion of date values now displays in a calendar format when
the complist module is available. Controllable by zstyle.
- New parameter UNDO_LIMIT_NO for more control over ZLE undo repeat.
- Several repairs/improvements to the contributed narrow-to-region
ZLE function.
- Many changes to child-process and signal handling to eliminate race
conditions and avoid deadlocks on descriptor and memory management.
- New builtin sysopen in zsh/system module for detailed control of
file descriptor modes.
zsh-5.1/README:
Incompatibilites between 5.0.8 and 5.1
--------------------------------------
The default behaviour when text is pasted into an X Windows terminal has
changed significantly (unless you are using a very old terminal emulator
that doesn't support this mode). Now, the new "bracketed paste mode"
treats all the pasted text as literal characters. This means, in
particular, that a newline is simply inserted as a visible newline; you
need to hit Return on the keyboard to execute the pasted text in one go.
See the description of zle_bracketed_paste in the zshparams manual for
more. "unset zle_bracketed_paste" restores the previous behaviour.
As noted in NEWS, the builtins declare, export, float, integer, local,
readonly and typeset now have corresponding reserved words that provide
true assignment semantics instead of an approximation by means of normal
command line arguments. It is hoped that this additional consistency
provides a more natural interface. However, compatbility with older
versions of zsh can be obtained by turning off the reserved word
interface, exposing the builtin interface:
disable -r declare export float integer local readonly typeset
This is also necessary in the unusual eventuality that the builtins are
to be overridden by shell functions, since reserved words take
precedence over functions.
- non-GNU du wouldn't complete filenames (taken from upstream)
- sort completion threw a syntax error on NetBSD (reported upstream)
Bump PKGREVISION to 1.
[tg] OpenBSD sync: handle integer base out of band like ksh93 does
[tg] Protect standard code (predefined aliases, internal code, aliases and functions in dot.mkshrc) from being overridden by aliases and, in some cases, shell functions (i.e. permit overriding but ignore it)
[tg] Implement GNU bash's enable for dot.mkshrc using magic aliases to redirect the builtins to external utilities; this differs from GNU bash in that enable takes precedence over functions
[tg] Move unaliasing an identifier when defining a POSIX-style function with the same name into lksh, as compatibility kludge
[tg] Korn shell style functions now have locally scoped shell options
[tg, iSKUNK] Change some ASCII-isms to be EBCDIC-aware or pluggable

[komh] OS/2 uses ; as PATH separator plus support drive letters
{perl>=5.16.6,p5-ExtUtils-ParseXS>=3.15}:../../devel/p5-ExtUtils-ParseXS
since pkgsrc enforces the newest perl version anyway, so they
should always pick perl, but sometimes (pkg_add) don't due to the
design of the {,} syntax.
No effective change for the above reason.

Changelog:
Changes from 5.0.7 to 5.0.8
---------------------------
- Global aliases can be created for syntactic tokens such as command
separators (";", "&", "|", "&&", "||"), redirection operators, etc.
Use at your own risk! The POSIX_ALIASES option is interpreted more
strictly to prevent expansion of these and other alias names containing
quotes, glob metacharacters, parameter references, etc.
- There have been various further improvements to builtin handling
with the POSIX_BUILTINS option (off by default) for compatibility with
the POSIX standard.
- 'whence -v' is now more informative, and 'whence -S' shows you
how a full chain of symbolic links resolves to a command.
- The 'p' parameter flag now allows an argument to be specified
as a reference to a variable, e.g. ${(ps.$sep.)foo} to split $foo
on a string given by $sep.
- The option FORCE_FLOAT now forces variables, not just constants,
to floating point in arithmetic expressions.
- The type of an assignment in arithmetic expressions, e.g. the
type seen by the variable res in $(( res = a = b )), is now
more logical and C-like.
- The default binding of 'u' in vi command mode has changed to undo
multiple changes when invoked repeatedly. '^R' is now bound to redo
changes. To revert to toggling of the last edit use:
bindkey -a u vi-undo-change
- Compatibility with Vim has been improved for vi editing mode. Most
notably, Vim style text objects are supported and the region can be
manipulated with vi commands in the same manner as Vim's visual mode.
- Elements of the watch variable may now be patterns.
- The logic for retrying history locking has been improved.
- Some rationalisations have been made to the zsh/db/gdbm module that
should make it more useful and predictable in operation.

the native tcsh, which isn't what anyone wants.
I believe these platforms to be: NetBSD, OpenBSD, Solaris -- if anyone
can confirm that others (especially old ones I can't readily check)
don't have a native tcsh, please add.

---------------------------
Thanks wiz@ for review.
5.0.7
This is version 5.0.7 of the shell. This is a stable release.
There are minor new features as well as bug fixes since 5.0.6.
Note in particular there is a security fix to disallow evaluation
of the initial values of integer variables imported from the
environment (they are instead treated as literal numbers). That
could allow local privilege escalation, under some specific and
atypical conditions where zsh is being invoked in privilege elevation
contexts when the environment has not been properly sanitized, such
as when zsh is invoked by sudo on systems where "env_reset" has
been disabled.
5.0.6
This is version 5.0.6 of the shell. This is a stable release.
There are minor new features as well as bug fixes since 5.0.5.
R50d is a required bugfix release:
- [Goodbox] Fix NULL pointer dereference on “unset x; nameref x”
- [tg] Fix severe regression in field splitting (LP#1378208)
- [tg] Add a warning about not using tainted user input (including from
the environ(7)ment) in arithmetics, until Stéphane writes it up nicely
R50c is a security fix release:
- [tg] Know more rare signals when generating sys_signame[] replacement
- [tg] OpenBSD sync (mostly RCSID only)
- [tg] Document HISTSIZE limit; found by luigi_345 on IRC
- [zacts] Fix link to Debian .mkshrc
- [tg] Cease exporting $RANDOM (Debian #760857)
- [tg] Fix C99 compatibility
- [tg] Work around klibc bug causing a coredump (Debian #763842)
- [tg] Use issetugid(2) as additional check if we are FPRIVILEGED
- [tg] SECURITY: do not permit += from environment
- [tg] Fix more field splitting bugs reported by Stephane Chazelas and
mikeserv; document current status wrt. ambiguous ones as testcases too
Fixes CVE-2014-6278:
A combination of nested command substitutions and function importing
from the environment can cause bash to execute code appearing in
the environment variable value following the function definition.

like last time, for 5.18, where this didn't lead to complaints.
Let me know if you have any this time.
This is a terse description of the new features added to bash-4.3 since
the release of bash-4.2. As always, the manual page (doc/bash.1) is
the place to look for complete descriptions.
1. New Features in Bash
a. The `helptopic' completion action now maps to all the help topics, not just
the shell builtins.
b. The `help' builtin no longer does prefix substring matching first, so
`help read' does not match `readonly', but will do it if exact string
matching fails.
c. The shell can be compiled to not display a message about processes that
terminate due to SIGTERM.
d. Non-interactive shells now react to the setting of checkwinsize and set
LINES and COLUMNS after a foreground job exits.
e. There is a new shell option, `globasciiranges', which, when set to on,
forces globbing range comparisons to use character ordering as if they
were run in the C locale.
f. There is a new shell option, `direxpand', which makes filename completion
expand variables in directory names in the way bash-4.1 did.
g. In Posix mode, the `command' builtin does not change whether or not a
builtin it shadows is treated as an assignment builtin.
h. The `return' and `exit' builtins accept negative exit status arguments.
i. The word completion code checks whether or not a filename containing a
shell variable expands to a directory name and appends `/' to the word
as appropriate. The same code expands shell variables in command names
when performing command completion.
j. In Posix mode, it is now an error to attempt to define a shell function
with the same name as a Posix special builtin.
k. When compiled for strict Posix conformance, history expansion is disabled
by default.
l. The history expansion character (!) does not cause history expansion when
followed by the closing quote in a double-quoted string.
m. `complete' and its siblings compgen/compopt now takes a new `-o noquote'
option to inhibit quoting of the completions.
n. Setting HISTSIZE to a value less than zero causes the history list to be
unlimited (setting it 0 zero disables the history list).
o. Setting HISTFILESIZE to a value less than zero causes the history file size
to be unlimited (setting it to 0 causes the history file to be truncated
to zero size).
p. The `read' builtin now skips NUL bytes in the input.
q. There is a new `bind -X' option to print all key sequences bound to Unix
commands.
r. When in Posix mode, `read' is interruptible by a trapped signal. After
running the trap handler, read returns 128+signal and throws away any
partially-read input.
s. The command completion code skips whitespace and assignment statements
before looking for the command name word to be completed.
t. The build process has a new mechanism for constructing separate help files
that better reflects the current set of compilation options.
u. The -nt and -ot options to test now work with files with nanosecond
timestamp resolution.
v. The shell saves the command history in any shell for which history is
enabled and HISTFILE is set, not just interactive shells.
w. The shell has `nameref' variables and new -n(/+n) options to declare and
unset to use them, and a `test -R' option to test for them.
x. The shell now allows assigning, referencing, and unsetting elements of
indexed arrays using negative subscripts (a[-1]=2, echo ${a[-1]}) which
count back from the last element of the array.
y. The {x}<word redirection feature now allows words like {array[ind]} and
can use variables with special meanings to the shell (e.g., BASH_XTRACEFD).
z. There is a new CHILD_MAX special shell variable; its value controls the
number of exited child statues the shell remembers.
aa. There is a new configuration option (--enable-direxpand-default) that
causes the `direxpand' shell option to be enabled by default.
bb. Bash does not do anything special to ensure that the file descriptor
assigned to X in {x}<foo remains open after the block containing it
completes.
cc. The `wait' builtin has a new `-n' option to wait for the next child to
change status.
dd. The `printf' %(...)T format specifier now uses the current time if no
argument is supplied.
ee. There is a new variable, BASH_COMPAT, that controls the current shell
compatibility level.
ff. The `popd' builtin now treats additional arguments as errors.
gg. The brace expansion code now treats a failed sequence expansion as a
simple string and will continue to expand brace terms in the remainder
of the word.
hh. Shells started to run process substitutions now run any trap set on EXIT.
ii. The fc builtin now interprets -0 as the current command line.
jj. Completing directory names containing shell variables now adds a trailing
slash if the expanded result is a directory.
kk. `cd' has a new `-@' option to browse a file's extended attributes on
systems that support O_XATTR.
ll. The test/[/[[ `-v variable' binary operator now understands array
references.
2. New Features in Readline
a. Readline is now more responsive to SIGHUP and other fatal signals when
reading input from the terminal or performing word completion but no
longer attempts to run any not-allowable functions from a signal handler
context.
b. There are new bindable commands to search the history for the string of
characters between the beginning of the line and the point
(history-substring-search-forward, history-substring-search-backward)
c. Readline allows quoted strings as the values of variables when setting
them with `set'. As a side effect, trailing spaces and tabs are ignored
when setting a string variable's value.
d. The history library creates a backup of the history file when writing it
and restores the backup on a write error.
e. New application-settable variable: rl_filename_stat_hook: a function called
with a filename before using it in a call to stat(2). Bash uses it to
expand shell variables so things like $HOME/Downloads have a slash
appended.
f. New bindable function `print-last-kbd-macro', prints the most-recently-
defined keyboard macro in a reusable format.
g. New user-settable variable `colored-stats', enables use of colored text
to denote file types when displaying possible completions (colored analog
of visible-stats).
h. New user-settable variable `keyseq-timout', acts as an inter-character
timeout when reading input or incremental search strings.
i. New application-callable function: rl_clear_history. Clears the history list
and frees all readline-associated private data.
j. New user-settable variable, show-mode-in-prompt, adds a characters to the
beginning of the prompt indicating the current editing mode.
k. New application-settable variable: rl_input_available_hook; function to be
called when readline detects there is data available on its input file
descriptor.
l. Readline calls an application-set event hook (rl_event_hook) after it gets
a signal while reading input (read returns -1/EINTR but readline does not
handle the signal immediately) to allow the application to handle or
otherwise note it.
m. If the user-settable variable `history-size' is set to a value less than
0, the history list size is unlimited.
n. New application-settable variable: rl_signal_event_hook; function that is
called when readline is reading terminal input and read(2) is interrupted
by a signal. Currently not called for SIGHUP or SIGTERM.
o. rl_change_environment: new application-settable variable that controls
whether or not Readline modifies the environment (currently readline
modifies only LINES and COLUMNS).

* Fix build on Debian GNU/kFreeBSD 7.3
* Update MASTER_SITES
Changelog:
This is version 5.0.5 of the shell. This is a stable release.
There are minor new features as well as bug fixes since 5.0.2.
5.0.3 and 5.0.4 were short-lived releases with most of the features of
5.0.5 that were replaced owing to significant bugs.
Incompatibilities between 5.0.2 and 5.0.5
-----------------------------------------
The "zshaddhistory" hook mechanism documented in the zshmisc manual page
has been upgraded so that a hook returning status 2 causes a history
line to be saved on the internal history list but not written to the
history file. Previously any non-zero status return would cause
the line not to be saved on the history at all. It is recommended
to use status 1 for this (indeed most shell users would naturally do
so).

(‘0’) as octal precisely iff “set -o posix” is active
[tg] Point out the octal digit and the integer arithmetic differences
from POSuX verbosely in the manual pages (point people who need octals
to “set -o posix” and who need longs to lksh) and elaborate on the
horrors of ISO C Undefined Behaviour which is allowed to delete all your
data
[tg] Unbreak “set -o” (list flags) in lksh on LP64 machines
[tg] Implement Emacs mode PgUp as Vi insert mode Cur↑ for Yofuh
[tg] Allow setting both “set -o sh” and “set -o posix”, if done in the

to fix segmentation fault just after invocation, at least on
NetBSD/amd64 6.1, which is reported as PR pkg/47917.
The problem was also reported by gcc (4.5.3) as:
main.c: In function 'main':
main.c:206:15: warning: assignment makes pointer from integer without a cast
At following location:
203 char *simplified;
....
206 simplified = canonicalize_file_name(current_wd);
to address issues with NetBSD-6(and earlier)'s fontconfig not being
new enough for pango.
While doing that, also bump freetype2 dependency to current pkgsrc
version.
Suggested by tron in PR 47882
a) refer 'perl' in their Makefile, or
b) have a directory name of p5-*, or
c) have any dependency on any p5-* package
Like last time, where this caused no complaints.
Should patch the configure script to respect the environment setting
of CC_FOR_GETHOST (or CC_FOR_BUILD or something), but this is less
work and will do for now.
Patch it up to use compile-tests rather than run-tests in autoconf
for many of its tests (OS-independently). Teach it about the few
remaining properties for NetBSD in particular.
ok agc

Changelog:
Changes since 5.0.0
-------------------
Numeric constants encountered in mathematical expressions (but not other
contexts) can contain underscores as separators that will be ignored on
evaluation, as allowed in other scripting languages. For example,
0xFFFF_FFFF, or 3.141_592_654.
"functions -T" turns on tracing for the specified function(s) only,
similar to "functions -t" except that tracing is turned off for any
functions called from the specified one(s) that don't also have the -t
or -T flag.
In file completion, the recursive-files style can be set to an array of
patterns to match against "$PWD/". In any matched location, it is
possibly to complete files in arbitrarily deep subdirectories without
needing to type the directory prefix. See example in the zshcompsys
manual.
The _user_expand completer now allows expansion functions in the
user-expand files to return a string in REPLY that will be used to name
the set of expansions returned.
Adam Hoka and hugor.
fish is a user friendly command line shell for UNIX-like operating
systems, written mainly with interactive use in mind. It differs
from other shells in that it only provides as few commands as
built-ins as possible and has a daemon which allows it to have
shared variables and command-line history between shell instances.
It also features feature-rich tab-completion and has command-line
syntax highlighting.

ref is a name reference to arr[i] has been fixed.
12-03-21 A bug in which assigning a compound variable into arr[i], where
arr[i] is an array variable did not work correctly has been fixed.

variables rather than those of type C, a, or A only has been fixed.
12-03-18 A bug in which unset foo where foo is a name reference to a compound
variable defined inside a function is not unset has been fixed.
12-03-18 A bug with SHOPT_EDPREDICT which could cause a core dump when the
list of matches became empty has been fixed.
12-03-15 The assignment, typeset -C foo=(a b c) now generates a syntax
error since a is not an assignment command.
12-03-16 A bug in which an unset discipline from a variable defined in a
subshell is not invoked in the subshell has been fixed.
12-03-08 The assignment typeset -a (x=1 y=2) now creates an index array

a compound variable.
12-03-02 +The vi and emacs edit modes now list all the entries in a directory
when entering a <tab> for completion after a /.

don't read-uninitialized for \177 in a here-doc
A DEL (0177, dec 127) byte in a here-document would cause dash to
access uninitialized memory at the end of one of the syntax.c
tables,
since those tables are sized to accommodate a maximum index of
BASESYNTAX + 126. Make the generated tables one byte larger.
printf ':<<\\E\n\200y\nE'|./dash
* src/mksyntax.c (filltable): Use 258, not 257 as the size,
so that BASESYNTAX(=130) + 127 is a valid index.
(print): Likewise.
Don't emit explicit array dimension in declaration.
* Avoid compiler warnings on isdigit.
* Add another missing LC_COLLATE to mkbuiltins.
* Fix NUL termination in readcmd.
* Lookup PWD after going through CDPATH.
* Pass EV_TESTED into evalcmd.
* Revert SKIPEVAL into EXEXIT.
* Add preliminary LINENO support.
* Honor tab as IFS whitespace when splitting fields in readcmd.
* Do not truncate file for FROMTO redirection.
* Fix quoted pattern patch breakage.
* Fix incorrect savefd conversions.
* Fix dowait signal race.
* Remove EXSIG.
* Do not close stderr when /dev/tty fails to open.
* Allow newlines after var name in for statements.
* Use CHKNL to parse case statements.
* Update manual page to differentiate dash from ash.
a window when the new patch file wasn't committed, and there's no check
for "extra" lines in distinfo, so this clearly identifies the version
with the new patch file included.
This unbreaks at least one of AST/ksh packages.

2010-03-09
This source and binary release contains a fix for the
2010-03-01 ksh memory leak plus a few minor fixes to clean
up the bit rot that accumulated since 2009-07-04.
See the release change log for details:
http://www2.research.att.com/~gsf/download/release.2010-03-09.2010-03-01.html
2010-03-01
This source and binary release contains minor fixes to the
unannounced 2010-02-02 release. It is the first official
non-beta release in almost 8 months (we really do try to
decrease the time between official releases, but the
abundance of moving targets sometimes makes that
interesting). See the release change log for details:
http://www2.research.att.com/~gsf/download/release.2010-03-01.2010-02-02.html
2010-02-02
This source and binary release includes:

2009-05-05
This source and binary release cleans up a few reported
build problems in the 2009-05-01 release (which has been
removed). The release procedures have been adjusted to avoid
similar problems in the future. (The main problem is
synthesizing external non-ast environments to fully exercise
portions of the build system seen by outside users -- since
we use our stuff for everything, including packaging and
building, setting up an environment that has no ast
components leaking in can be non-trivial).
See the release change log for details:
http://www2.research.att.com/~gsf/download/release.2009-05-05.2009-05-01.html
2009-05-01
This source release contains the official (and hopefully
final) ksh93t+ 2009-05-01, along with updates for the ast
commands and libraries. A lot of work went into cleaning up
the regression tests -- most regressions directly correspond
to unsupported native system features or buggy native system
interfaces that we felt should be fixed rather than worked around.
Of course we could be persuaded otherwise.

http://www2.research.att.com/~gsf/download/release.2009-05-01.2008-11-04.html

This release addresses standalone build problems and issues
raised on the lists. It also contains the final ksh93s+ release.

http://www2.research.att.com/~gsf/download/release.2007-11-05.2007-03-28.html
2007-03-28
Yes -- a new release in only 3 months. This release contains
fixes and features that address the issues raised on the lists.
A summary of recent ksh93 changes:
1. Double precision floating point arithmetic with full C99
arithmetic support on systems that provide the C99
arithmetic functions. The numbers Inf and NaN can be
used in arithmetic expressions.
2. TAB-TAB completion generates a numbered list of
completions which the user can select.
3. Support for processing/handling multibyte locales (e.g.,
en_US.UTF-8, hi_IN.UTF-8, ja_JP.eucJP, zh_CN.GB18030,
zh_TW.BIG5 etc.) has been extensively revised, tested,
and is now supported even on the language level (e.g.
variable and function identifiers may contain locale
specific codeset characters).
4. /dev/(tcp|udp|sctp)/host/sevrice now handles IPv6
addresses on systems that provide getaddrinfo(3).
5. The ability to seek on a file by offset or content with
new redirection operators.
6. A new --showme option which allows portions of a script
to behave as if -x were specified while other parts
execute as usual. This simplifies the coding of make -n
style semantics at the script level by eliminating code
replication. In particular, io redirections are handled
by --showme.
7. The [[...]] operator =~ has been added which compares
the string to an extended regular expression rather than
== which compares against a shell pattern.
8. The printf(1) builtin has been extended to support the =
flag for centering a field. The # flag when used with
%d and %i provides values in units of thousands or 1024
respectively with an appropriate suffix added.
9. Example screenshots from joint work with the Solaris
ksh93 integration project are available here.

2007-01-11
This release, almost a year from the last big release,
contains changes based on feedback from the { ast-users
ast-developers uwin-users uwin-developers } lists and the
ongoing ksh93-solaris integration project. Thanks to all
who helped. Our resolution this year is to increase release
frequency to keep internal and external source/binaries
more in sync. See the release change log for details:

This package will install tcsh in the /bin directory (not ${LOCALBASE}/bin).
DragonFly already has tcsh in the base system, so this package will replace
it with no ability to restore the system version. This is not desired.
shells/tcsh still works should there be any need for a pkgsrc version installed
at ${LOCALBASE}/bin.

[tg, RT] Move mirtoconf checks and INCLUDES_ONLY parts of
sh.h around to ensure prerequisites are always available
[tg, RT, ir0nh34d] Pass mksh.exe to testsuite, if such thing is generated,
and deal with Cygwin passing just "mksh" in argv[0] in such cases
[tg] Imply -DMKSH_ASSUME_UTF8=0 on MSYS; optimise checks
[tg, Jb_boin] Fix regression introduced in R35b by jaredy's security

leading #!.
b. Subshells begun to execute command substitutions or run shell functions or
builtins in subshells do not reset trap strings until a new trap is
specified. This allows $(trap) to display the caller's traps and the
trap strings to persist until a new trap is set.
c. `trap -p' will now show signals ignored at shell startup, though their
disposition still cannot be modified.
d. $'...', echo, and printf understand \uXXXX and \UXXXXXXXX escape sequences.
e. declare/typeset has a new `-g' option, which creates variables in the
global scope even when run in a shell function.
f. test/[/[[ have a new -v variable unary operator, which returns success if
`variable' has been set.
g. Posix parsing changes to allow `! time command' and multiple consecutive
instances of `!' (which toggle) and `time' (which have no cumulative
effect).
h. Posix change to allow `time' as a command by itself to print the elapsed
user, system, and real times for the shell and its children.
j. $((...)) is always parsed as an arithmetic expansion first, instead of as
a potential nested command substitution, as Posix requires.
k. A new FUNCNEST variable to allow the user to control the maximum shell
function nesting (recursive execution) level.
l. The mapfile builtin now supplies a third argument to the callback command:
the line about to be assigned to the supplied array index.
m. The printf builtin has a new %(fmt)T specifier, which allows time values
to use strftime-like formatting.
n. There is a new `compat41' shell option.
o. The cd builtin has a new Posix-mandated `-e' option.
p. Negative subscripts to indexed arrays, previously errors, now are treated
as offsets from the maximum assigned index + 1.
q. Negative length specifications in the ${var:offset:length} expansion,
previously errors, are now treated as offsets from the end of the variable.
r. Parsing change to allow `time -p --'.
s. Posix-mode parsing change to not recognize `time' as a keyword if the
following token begins with a `-'. This means no more Posix-mode
`time -p'. Posix interpretation 267.
t. There is a new `lastpipe' shell option that runs the last command of a
pipeline in the current shell context. The lastpipe option has no
effect if job control is enabled.
u. History expansion no longer expands the `$!' variable expansion.
v. Posix mode shells no longer exit if a variable assignment error occurs
with an assignment preceding a command that is not a special builtin.
w. Non-interactive mode shells exit if -u is enabled and an attempt is made
to use an unset variable with the % or # expansions, the `//', `^', or
`,' expansions, or the parameter length expansion.
x. Posix-mode shells use the argument passed to `.' as-is if a $PATH search
fails, effectively searching the current directory. Posix-2008 change.
2. New Features in Readline
a. The history library does not try to write the history filename in the
current directory if $HOME is unset. This closes a potential security
problem if the application does not specify a history filename.
b. New bindable variable `completion-display-width' to set the number of
columns used when displaying completions.
c. New bindable variable `completion-case-map' to cause case-insensitive
completion to treat `-' and `_' as identical.
d. There are new bindable vi-mode command names to avoid readline's case-
insensitive matching not allowing them to be bound separately.
e. New bindable variable `menu-complete-display-prefix' causes the menu
completion code to display the common prefix of the possible completions
before cycling through the list, instead of after.
to trigger/signal a rebuild for the transition 5.10.1 -> 5.12.1.
The list of packages is computed by finding all packages which end
up having either of PERL5_USE_PACKLIST, BUILDLINK_API_DEPENDS.perl,
or PERL5_PACKLIST defined in their make setup (tested via
"make show-vars VARNAMES=..."), minus the packages updated after
the perl package update.
sno@ was right after all, obache@ kindly asked and he@ led the
way. Thanks!
