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).
Added completions for:
VBoxHeadless (#3378)
VBoxSDL (#3378)
base64 (#3378)
caffeinate (#3524)
dconf (#3638)
dig (#3495)
dpkg-reconfigure (#3521 & #3522)

sysbench (#3491)
tmutil (#3524)
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).
Release Notes for fish 2.3.0 (released May 20, 2016)
Significant Changes
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)

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.

on illumos SunOS 5.11 this actually goes a real long way over stock sh/ksh!

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.

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.

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.
Include mk/bsd.prefs.mk before the shells/tcsh/Makefile so the
OS_VARIANT variable is available for testing.

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.
