fish 3.2.2 (released April 7, 2021)
====================================
This release of fish fixes a number of additional issues identified in the fish 3.2 series:
- The command-not-found handler used suggestions from ``pacman`` on Arch Linux, but this caused major slowdowns on some systems and has been disabled (:issue:`7841`).
- fish will no longer hang on exit if another process is in the foreground on macOS (:issue:`7901`).
- Certain programs (such as ``lazygit``) could create situations where fish would not receive keystrokes correctly, but it is now more robust in these situations (:issue:`7853`).
- Arguments longer than 1024 characters no longer trigger excessive CPU usage on macOS (:issue:`7837`).
- fish builds correctly on macOS when using new versions of Xcode (:issue:`7838`).
- Completions for ``aura`` (:issue:`7865`) and ``tshark`` (:issue:`7858`) should no longer produce errors.
- Background jobs no longer interfere with syntax highlighting (a regression introduced in fish 3.2.1, :issue:`7842`).
If you are upgrading from version 3.1.2 or before, please also review the release notes for 3.2.1 and 3.2.0 (included below).
fish 3.2.1 (released March 18, 2021)
====================================
This release of fish fixes the following problems identified in fish 3.2.0:
- Commands in key bindings are run with fish's internal terminal modes, instead of the terminal modes typically used for commands. This fixes a bug introduced in 3.2.0, where text would unexpectedly appear on the terminal, especially when pasting (:issue:`7770`).
- Prompts which use the internal ``__fish_print_pipestatus`` function will display correctly rather than carrying certain modifiers (such as bold) further than intended (:issue:`7771`).
- Redirections to internal file descriptors is allowed again, reversing the changes in 3.2.0. This fixes a problem with Midnight Commander (:issue:`7769`).
- Universal variables should be fully reliable regardless of operating system again (:issue:`7774`).
- ``fish_git_prompt`` no longer causes screen flickering in certain terminals (:issue:`7775`).
- ``fish_add_path`` manipulates the ``fish_user_paths`` variable correctly when moving multiple paths (:issue:`7776`).
- Pasting with a multi-line command no longer causes a ``__fish_tokenizer_state`` error (:issue:`7782`).
- ``psub`` inside event handlers cleans up temporary files properly (:issue:`7792`).
- Event handlers declared with ``--on-job-exit $fish_pid`` no longer run constantly (:issue:`7721`), although these functions should use ``--on-event fish_exit`` instead.
- Changing terminal modes inside ``config.fish`` works (:issue:`7783`).
- ``set_color --print-colors`` no longer prints all colors in bold (:issue:`7805`)
- Completing commands starting with a ``-`` no longer prints an error (:issue:`7809`).
- Running ``fish_command_not_found`` directly no longer produces an error on macOS or other OSes which do not have a handler available (:issue:`7777`).
- The new ``type`` builtin now has the (deprecated) ``--quiet`` long form of ``-q`` (:issue:`7766`).
It also includes some small enhancements:
- ``help`` and ``fish_config`` work correctly when fish is running in a Chrome OS Crostini Linux VM (:issue:`7789`).
- The history file can be made a symbolic link without it being overwritten (:issue:`7754`), matching a similar improvement for the universal variable file in 3.2.0.
- An unhelpful error ("access: No error"), seen on Cygwin, is no longer produced (:issue:`7785`).
- Improvements to the ``rsync`` completions (:issue:`7763`), some completion descriptions (:issue:`7788`), and completions that use IP address (:issue:`7787`).
- Improvements to the appearance of ``fish_config`` (:issue:`7811`).
If you are upgrading from version 3.1.2 or before, please also review
the release notes for 3.2.0 (included below).
fish 3.2.0 (released March 1, 2021)
===================================
Notable improvements and fixes
------------------------------
- **Undo and redo support** for the command-line editor and pager search (:issue:`1367`). By default, undo is bound to Control+Z, and redo to Alt+/.
- **Builtins can now output before all data is read**. For example, ``string replace`` no longer has to read all of stdin before it can begin to output.
This makes it usable also for pipes where the previous command hasn't finished yet, like::
# Show all dmesg lines related to "usb"
dmesg -w | string match '*usb*'
- **Prompts will now be truncated** instead of replaced with ``"> "`` if they are wider than the terminal (:issue:`904`).
For example::
~/dev/build/fish-shell-git/src/fish-shell/build (makepkg)>
will turn into::
…h-shell/build (makepkg)>
It is still possible to react to the ``COLUMNS`` variable inside the prompt to implement smarter behavior.
- **fish completes ambiguous completions** after pressing :kbd:`Tab` even when they
have a common prefix, without the user having to press :kbd:`Tab` again
(:issue:`6924`).
- fish is less aggressive about resetting terminal modes, such as flow control, after every command.
Although flow control remains off by default, enterprising users can now enable it with
``stty`` (:issue:`2315`, :issue:`7704`).
- A new **"fish_add_path" helper function to add paths to $PATH** without producing duplicates,
to be used interactively or in ``config.fish`` (:issue:`6960`, :issue:`7028`).
For example::
fish_add_path /opt/mycoolthing/bin
will add /opt/mycoolthing/bin to the beginning of $fish_user_path without creating duplicates,
so it can be called safely from config.fish or interactively, and the path will just be there, once.
- **Better errors with "test"** (:issue:`6030`)::
> test 1 = 2 and echo true or false
test: Expected a combining operator like '-a' at index 4
1 = 2 and echo true or echo false
^
This includes numbering the index from 1 instead of 0, like fish lists.
- **A new theme for the documentation and Web-based configuration** (:issue:`6500`, :issue:`7371`, :issue:`7523`), matching the design on fishshell.com.
- ``fish --no-execute`` **will no longer complain about unknown commands**
or non-matching wildcards, as these could be defined differently at
runtime (especially for functions). This makes it usable as a static syntax checker (:issue:`977`).
- ``string match --regex`` now integrates **named PCRE2 capture groups as fish variables**, allowing variables to be set directly from ``string match`` (:issue:`7459`). To support this functionality, ``string`` is now a reserved word and can no longer be wrapped in a function.
- Globs and other **expansions are limited to 512,288 results** (:issue:`7226`). Because operating systems limit the number of arguments to commands, larger values are unlikely to work anyway, and this helps to avoid hangs.
- A new **"fish for bash users" documentation page** gives a quick overview of the scripting differences between bash and fish (:issue:`2382`), and the completion tutorial has also been moved out into its own document (:issue:`6709`).
Syntax changes and new commands
-------------------------------
- Range limits in index range expansions like ``$x[$start..$end]`` may be omitted: ``$start`` and ``$end`` default to 1 and -1 (the last item) respectively (:issue:`6574`)::
echo $var[1..]
echo $var[..-1]
echo $var[..]
All print the full list ``$var``.
- When globbing, a segment which is exactly ``**`` may now match zero directories. For example ``**/foo`` may match ``foo`` in the current directory (:issue:`7222`).
Scripting improvements
----------------------
- The ``type``, ``_`` (gettext), ``.`` (source) and ``:`` (no-op) functions
are now implemented builtins for performance purposes (:issue:`7342`, :issue:`7036`, :issue:`6854`).
- ``set`` and backgrounded jobs no longer overwrite ``$pipestatus`` (:issue:`6820`), improving its use in command substitutions (:issue:`6998`).
- Computed ("electric") variables such as ``status`` are now only global in scope, so ``set -Uq status`` returns false (:issue:`7032`).
- The output for ``set --show`` has been shortened, only mentioning the scopes in which a variable exists (:issue:`6944`).
In addition, it now shows if a variable is a path variable.
- A new variable, ``fish_kill_signal``, is set to the signal that terminated the last foreground job, or ``0`` if the job exited normally (:issue:`6824`, :issue:`6822`).
- A new subcommand, ``string pad``, allows extending strings to a given width (:issue:`7340`, :issue:`7102`).
- ``string sub`` has a new ``--end`` option to specify the end index of
a substring (:issue:`6765`, :issue:`5974`).
- ``string split`` has a new ``--fields`` option to specify fields to
output, similar to ``cut -f`` (:issue:`6770`).
- ``string trim`` now also trims vertical tabs by default (:issue:`6795`).
- ``string replace`` no longer prints an error if a capturing group wasn't matched, instead treating it as empty (:issue:`7343`).
- ``string`` subcommands now quit early when used with ``--quiet`` (:issue:`7495`).
- ``string repeat`` now handles multiple arguments, repeating each one (:issue:`5988`).
- ``printf`` no longer prints an error if not given an argument (not
even a format string).
- The ``true`` and ``false`` builtins ignore any arguments, like other shells (:issue:`7030`).
- ``fish_indent`` now removes unnecessary quotes in simple cases (:issue:`6722`)
and gained a ``--check`` option to just check if a file is indented correctly (:issue:`7251`).
- ``fish_indent`` indents continuation lines that follow a line ending in a backslash, ``|``, ``&&`` or ``||``.
- ``pushd`` only adds a directory to the stack if changing to it was successful (:issue:`6947`).
- A new ``fish_job_summary`` function is called whenever a
background job stops or ends, or any job terminates from a signal (:issue:`6959`, :issue:`2727`, :issue:`4319`).
The default behaviour can now be customized by redefining it.
- ``status`` gained new ``dirname`` and ``basename`` convenience subcommands
to get just the directory to the running script or the name of it,
to simplify common tasks such as running ``(dirname (status filename))`` (:issue:`7076`, :issue:`1818`).
- Broken pipelines are now handled more smoothly; in particular, bad redirection mid-pipeline
results in the job continuing to run but with the broken file descriptor replaced with a closed
file descriptor. This allows better error recovery and is more in line with other shells'
behaviour (:issue:`7038`).
- ``jobs --quiet PID`` no longer prints "no suitable job" if the job for PID does not exist (eg because it has finished) (:issue:`6809`, :issue:`6812`).
- ``jobs`` now shows continued child processes correctly (:issue:`6818`)
- ``disown`` should no longer create zombie processes when job control is off, such as in ``config.fish`` (:issue:`7183`).
- ``command``, ``jobs`` and ``type`` builtins support ``--query`` as the long form of ``-q``, matching other builtins.
The long form ``--quiet`` is deprecated (:issue:`7276`).
- ``argparse`` no longer requires a short flag letter for long-only options (:issue:`7585`)
and only prints a backtrace with invalid options to argparse itself (:issue:`6703`).
- ``argparse`` now passes the validation variables (e.g. ``$_flag_value``) as local-exported variables,
avoiding the need for ``--no-scope-shadowing`` in validation functions.
- ``complete`` takes the first argument as the name of the command if the ``--command``/``-c`` option is not used,
so ``complete git`` is treated like ``complete --command git``,
and it can show the loaded completions for specific commands with ``complete COMMANDNAME`` (:issue:`7321`).
- ``set_color -b`` (without an argument) no longer prints an error message, matching other invalid invocations of this command (:issue:`7154`).
- ``exec`` no longer produces a syntax error when the command cannot be found (:issue:`6098`).
- ``set --erase`` and ``abbr --erase`` can now erase multiple things in one go, matching ``functions --erase`` (:issue:`7377`).
- ``abbr --erase`` no longer prints errors when used with no arguments or on an unset abbreviation (:issue:`7376`, :issue:`7732`).
- ``test -t``, for testing whether file descriptors are connected to a terminal, works for file descriptors 0, 1, and 2 (:issue:`4766`).
It can still return incorrect results in other cases (:issue:`1228`).
- Trying to execute scripts with Windows line endings (CRLF) produces a sensible error (:issue:`2783`).
- Trying to execute commands with arguments that exceed the operating system limit now produces a specific error (:issue:`6800`).
- An ``alias`` that delegates to a command with the same name no longer triggers an error about recursive completion (:issue:`7389`).
- ``math`` now has a ``--base`` option to output the result in hexadecimal or octal (:issue:`7496`) and produces more specific error messages (:issue:`7508`).
- ``math`` learned bitwise functions ``bitand``, ``bitor`` and ``bitxor``, used like ``math "bitand(0xFE, 5)"`` (:issue:`7281`).
- ``math`` learned tau for those who don't like typing "2 * pi".
- Failed redirections will now set ``$status`` (:issue:`7540`).
- fish sets exit status in a more consistent manner after errors, including invalid expansions like ``$foo[``.
- Using ``read --silent`` while fish is in private mode was adding these potentially-sensitive entries to the history; this has been fixed (:issue:`7230`).
- ``read`` can now read interactively from other files, and can be used to read from the terminal via ``read </dev/tty`` (if the operating system provides ``/dev/tty``) (:issue:`7358`).
- A new ``fish_status_to_signal`` function for transforming exit statuses to signal names has been added (:issue:`7597`, :issue:`7595`).
- The fallback ``realpath`` builtin supports the ``-s``/``--no-symlinks`` option, like GNU realpath (:issue:`7574`).
- ``functions`` and ``type`` now explain when a function was defined via ``source`` instead of just saying ``Defined in -``.
- Significant performance improvements when globbing, appending to variables or in ``math``.
- ``echo`` no longer interprets options at the beginning of an argument (eg ``echo "-n foo"``) (:issue:`7614`).
- fish now finds user configuration even if the ``HOME`` environment variable is not set (:issue:`7620`).
- fish no longer crashes when started from a Windows-style working directory (eg ``F:\path``) (:issue:`7636`).
- ``fish -c`` now reads the remaining arguments into ``$argv`` (:issue:`2314`).
- The ``pwd`` command supports the long options ``--logical`` and ``--physical``, matching other implementations (:issue:`6787`).
- ``fish --profile`` now only starts profiling after fish is ready to execute commands (all configuration is completed). There is a new ``--profile-startup`` option that only profiles the startup and configuration process (:issue:`7648`).
- Builtins return a maximum exit status of 255, rather than potentially overflowing. In particular, this affects ``exit``, ``return``, ``functions --query``, and ``set --query`` (:issue:`7698`, :issue:`7702`).
- It is no longer an error to run builtin with closed stdin. For example ``count <&-`` now prints 0, instead of failing.
- Blocks, functions, and builtins no longer permit redirecting to file descriptors other than 0 (standard input), 1 (standard output) and 2 (standard error). For example, ``echo hello >&5`` is now an error. This prevents corruption of internal state (#3303).
Interactive improvements
------------------------
- fish will now always attempt to become process group leader in interactive mode (:issue:`7060`). This helps avoid hangs in certain circumstances, and allows tmux's current directory introspection to work (:issue:`5699`).
- The interactive reader now allows ending a line in a logical operators (``&&`` and ``||``) instead of complaining about a missing command. (This was already syntactically valid, but interactive sessions didn't know about it yet).
- The prompt is reprinted after a background job exits (:issue:`1018`).
- fish no longer inserts a space after a completion ending in ``.``, ``,`` or ``-`` is accepted, improving completions for tools that provide dynamic completions (:issue:`6928`).
- If a filename is invalid when first pressing :kbd:`Tab`, but becomes valid, it will be completed properly on the next attempt (:issue:`6863`).
- ``help string match/replace/<subcommand>`` will show the help for string subcommands (:issue:`6786`).
- ``fish_key_reader`` sets the exit status to 0 when used with ``--help`` or ``--version`` (:issue:`6964`).
- ``fish_key_reader`` and ``fish_indent`` send output from ``--version`` to standard output, matching other fish binaries (:issue:`6964`).
- A new variable ``$status_generation`` is incremented only when the previous command produces an exit status (:issue:`6815`). This can be used, for example, to check whether a failure status is a holdover due to a background job, or actually produced by the last run command.
- ``fish_greeting`` is now a function that reads a variable of the same name, and defaults to setting it globally.
This removes a universal variable by default and helps with updating the greeting.
However, to disable the greeting it is now necessary to explicitly specify universal scope (``set -U fish_greeting``) or to disable it in config.fish (:issue:`7265`).
- Events are properly emitted after a job is cancelled (:issue:`2356`).
- ``fish_preexec`` and ``fish_postexec`` events are no longer triggered for empty commands (:issue:`4829`, :issue:`7085`).
- Functions triggered by the ``fish_exit`` event are correctly run when the terminal is closed or the shell receives SIGHUP (:issue:`7014`).
- The ``fish_prompt`` event no longer fires when ``read`` is used. If
you need a function to run any time ``read`` is invoked by a script,
use the new ``fish_read`` event instead (:issue:`7039`).
- A new ``fish_posterror`` event is emitted when attempting to execute a command with syntax errors (:issue:`6880`, :issue:`6816`).
- The debugging system has now fully switched from the old numbered level to the new named category system introduced in 3.1. A number of new debugging categories have been added, including ``config``, ``path``, ``reader`` and ``screen`` (:issue:`6511`). See the output of ``fish --print-debug-categories`` for the full list.
- The warning about read-only filesystems has been moved to a new "warning-path" debug category
and can be disabled by setting a debug category of ``-warning-path`` (:issue:`6630`)::
fish --debug=-warning-path
- The enabled debug categories are now printed on shell startup (:issue:`7007`).
- The ``-o`` short option to fish, for ``--debug-output``, works correctly instead of producing an
invalid option error (:issue:`7254`).
- fish's debugging can now also be enabled via ``FISH_DEBUG`` and ``FISH_DEBUG_OUTPUT`` environment variables.
This helps with debugging when no commandline options can be passed, like when fish is called in a shebang (:issue:`7359`).
- Abbreviations are now expanded after all command terminators (eg ``;`` or ``|``), not just space,
as in fish 2.7.1 and before (:issue:`6970`), and after closing a command substitution (:issue:`6658`).
- The history file is now created with user-private permissions,
matching other shells (:issue:`6926`). The directory containing the history
file was already private, so there should not have been any private data
revealed.
- The output of ``time`` is now properly aligned in all cases (:issue:`6726`, :issue:`6714`) and no longer depends on locale (:issue:`6757`).
- The command-not-found handling has been simplified.
When it can't find a command, fish now just executes a function called ``fish_command_not_found``
instead of firing an event, making it easier to replace and reason about.
Previously-defined ``__fish_command_not_found_handler`` functions with an appropriate event listener will still work (:issue:`7293`).
- :kbd:`Control-C` handling has been reimplemented in C++ and is therefore quicker (:issue:`5259`), no longer occasionally prints an "unknown command" error (:issue:`7145`) or overwrites multiline prompts (:issue:`3537`).
- :kbd:`Control-C` no longer kills background jobs for which job control is
disabled, matching POSIX semantics (:issue:`6828`, :issue:`6861`).
- Autosuggestions work properly after :kbd:`Control-C` cancels the current commmand line (:issue:`6937`).
- History search is now case-insensitive unless the search string contains an uppercase character (:issue:`7273`).
- ``fish_update_completions`` gained a new ``--keep`` option, which improves speed by skipping completions that already exist (:issue:`6775`, :issue:`6796`).
- Aliases containing an embedded backslash appear properly in the output of ``alias`` (:issue:`6910`).
- ``open`` no longer hangs indefinitely on certain systems, as a bug in ``xdg-open`` has been worked around (:issue:`7215`).
- Long command lines no longer add a blank line after execution (:issue:`6826`) and behave better with :kbd:`Backspace` (:issue:`6951`).
- ``functions -t`` works like the long option ``--handlers-type``, as documented, instead of producing an error (:issue:`6985`).
- History search now flashes when it found no more results (:issue:`7362`)
- fish now creates the path in the environment variable ``XDG_RUNTIME_DIR`` if it does not exist, before using it for runtime data storage (:issue:`7335`).
- ``set_color --print-colors`` now also respects the bold, dim, underline, reverse, italic and background modifiers, to better show their effect (:issue:`7314`).
- The fish Web configuration tool (``fish_config``) shows prompts correctly on Termux for Android (:issue:`7298`) and detects Windows Services for Linux 2 properly (:issue:`7027`). It no longer shows the ``history`` variable as it may be too large (one can use the History tab instead). It also starts the browser in another thread, avoiding hangs in some circumstances, especially with Firefox's Developer Edition (:issue:`7158`). Finally, a bug in the Source Code Pro font may cause browsers to hang, so this font is no longer chosen by default (:issue:`7714`).
- ``funcsave`` gained a new ``--directory`` option to specify the location of the saved function (:issue:`7041`).
- ``help`` works properly on MSYS2 (:issue:`7113`) and only uses ``cmd.exe`` if running on WSL (:issue:`6797`).
- Resuming a piped job by its number, like ``fg %1``, works correctly (:issue:`7406`). Resumed jobs show the correct title in the terminal emulator (:issue:`7444`).
- Commands run from key bindings now use the same TTY modes as normal commands (:issue:`7483`).
- Autosuggestions from history are now case-sensitive (:issue:`3978`).
- ``$status`` from completion scripts is no longer passed outside the completion, which keeps the status display in the prompt as the last command's status (:issue:`7555`).
- Updated localisations for pt_BR (:issue:`7480`).
- ``fish_trace`` output now starts with ``->`` (like ``fish --profile``), making the depth more visible (:issue:`7538`).
- Resizing the terminal window no longer produces a corrupted prompt (:issue:`6532`, :issue:`7404`).
- ``functions`` produces an error rather than crashing on certain invalid arguments (:issue:`7515`).
- A crash in completions with inline variable assignment (eg ``A= b``) has been fixed (:issue:`7344`).
- ``fish_private_mode`` may now be changed dynamically using ``set`` (:issue:`7589`), and history is kept in memory in private mode (but not stored permanently) (:issue:`7590`).
- Commands with leading spaces may be retrieved from history with up-arrow until a new command is run, matching zsh's ``HIST_IGNORE_SPACE`` (:issue:`1383`).
- Importing bash history or reporting errors with recursive globs (``**``) no longer hangs (:issue:`7407`, :issue:`7497`).
- ``bind`` now shows ``\x7f`` for the del key instead of a literal DEL character (:issue:`7631`)
- Paths containing variables or tilde expansion are only suggested when they are still valid (:issue:`7582`).
- Syntax highlighting can now color a command as invalid even if executed quickly (:issue:`5912`).
- Redirection targets are no longer highlighted as error if they contain variables which will likely be defined by the current commandline (:issue:`6654`).
- fish is now more resilient against broken terminal modes (:issue:`7133`, :issue:`4873`).
- fish handles being in control of the TTY without owning its own process group better, avoiding some hangs in special configurations (:issue:`7388`).
- Keywords can now be colored differently by setting the ``fish_color_keyword`` variable (``fish_color_command`` is used as a fallback) (:issue:`7678`).
- Just like ``fish_indent``, the interactive reader will indent continuation lines that follow a line ending in a backslash, ``|``, ``&&`` or ``||`` (:issue:`7694`).
- Commands with a trailing escaped space are saved in history correctly (:issue:`7661`).
- ``fish_prompt`` no longer mangles Unicode characters in the private-use range U+F600-U+F700. (:issue:`7723`).
- The universal variable file, ``fish_variables``, can be made a symbolic link without it being overwritten (:issue:`7466`).
- fish is now more resilient against ``mktemp`` failing (:issue:`7482`).
New or improved bindings
^^^^^^^^^^^^^^^^^^^^^^^^
- As mentioned above, new special input functions ``undo`` (:kbd:`Control+\_` or :kbd:`Control+Z`) and ``redo`` (:kbd:`Alt-/`) can be used to revert changes to the command line or the pager search field (:issue:`6570`).
- :kbd:`Control-Z` is now available for binding (:issue:`7152`).
- Additionally, using the ``cancel`` special input function (bound to :kbd:`Escape` by default) right after fish picked an unambiguous completion will undo that (:issue:`7433`).
- ``fish_clipboard_paste`` (:kbd:`Control+V`) trims indentation from multiline commands, because fish already indents (:issue:`7662`).
- Vi mode bindings now support ``dh``, ``dl``, ``c0``, ``cf``, ``ct``, ``cF``, ``cT``, ``ch``, ``cl``, ``y0``, ``ci``, ``ca``, ``yi``, ``ya``, ``di``, ``da``, ``d;``, ``d,``, ``o``, ``O`` and Control+left/right keys to navigate by word (:issue:`6648`, :issue:`6755`, :issue:`6769`, :issue:`7442`, :issue:`7516`).
- Vi mode bindings support :kbd:`~` (tilde) to toggle the case of the selected character (:issue:`6908`).
- Functions ``up-or-search`` and ``down-or-search`` (:kbd:`Up` and :kbd:`Down`) can cross empty lines, and don't activate search mode if the search fails, which makes them easier to use to move between lines in some situations.
- If history search fails to find a match, the cursor is no longer moved. This is useful when accidentally starting a history search on a multi-line commandline.
- The special input function ``beginning-of-history`` (:kbd:`Page Up`) now moves to the oldest search instead of the youngest - that's ``end-of-history`` (:kbd:`Page Down`).
- A new special input function ``forward-single-char`` moves one character to the right, and if an autosuggestion is available, only take a single character from it (:issue:`7217`, :issue:`4984`).
- Special input functions can now be joined with ``or`` as a modifier (adding to ``and``), though only some commands set an exit status (:issue:`7217`). This includes ``suppress-autosuggestion`` to reflect whether an autosuggestion was suppressed (:issue:`1419`)
- A new function ``__fish_preview_current_file``, bound to :kbd:`Alt+O`, opens the
current file at the cursor in a pager (:issue:`6838`, :issue:`6855`).
- ``edit_command_buffer`` (:kbd:`Alt-E` and :kbd:`Alt-V`) passes the cursor position
to the external editor if the editor is recognized (:issue:`6138`, :issue:`6954`).
- ``__fish_prepend_sudo`` (:kbd:`Alt-S`) now toggles a ``sudo`` prefix (:issue:`7012`) and avoids shifting the cursor (:issue:`6542`).
- ``__fish_prepend_sudo`` (:kbd:`Alt-S`) now uses the previous commandline if the current one is empty,
to simplify rerunning the previous command with ``sudo`` (:issue:`7079`).
- ``__fish_toggle_comment_commandline`` (:kbd:`Alt-#`) now uncomments and presents the last comment
from history if the commandline is empty (:issue:`7137`).
- ``__fish_whatis_current_token`` (:kbd:`Alt-W`) prints descriptions for functions and builtins (:issue:`7191`, :issue:`2083`).
- The definition of "word" and "bigword" for movements was refined, fixing (eg) vi mode's behavior with :kbd:`e` on the second-to-last char, and bigword's behavior with single-character words and non-blank non-graphical characters (:issue:`7353`, :issue:`7354`, :issue:`4025`, :issue:`7328`, :issue:`7325`)
- fish's clipboard bindings now also support Windows Subsystem for Linux via PowerShell and clip.exe (:issue:`7455`, :issue:`7458`) and will properly copy newlines in multi-line commands.
- Using the ``*-jump`` special input functions before typing anything else no longer crashes fish.
- Completing variable overrides (``foo=bar``) could replace the entire thing with just the completion in some circumstances. This has been fixed (:issue:`7398`).
Improved prompts
^^^^^^^^^^^^^^^^
- The default and example prompts print the correct exit status for
commands prefixed with ``not`` (:issue:`6566`).
- git prompts include all untracked files in the repository, not just those in the current
directory (:issue:`6086`).
- The git prompts correctly show stash states (:issue:`6876`, :issue:`7136`) and clean states (:issue:`7471`).
- The Mercurial prompt correctly shows untracked status (:issue:`6906`), and by default only shows the branch for performance reasons.
A new variable ``$fish_prompt_hg_show_informative_status`` can be set to enable more information.
- The ``fish_vcs_prompt`` passes its arguments to the various VCS prompts that it calls (:issue:`7033`).
- The Subversion prompt was broken in a number of ways in 3.1.0 and has been restored (:issue:`6715`, :issue:`7278`).
- A new helper function ``fish_is_root_user`` simplifies checking for superuser privilege (:issue:`7031`, :issue:`7123`).
- New colorschemes - ``ayu Light``, ``ayu Dark`` and ``ayu Mirage`` (:issue:`7596`).
- Bugs related to multiline prompts, including repainting (:issue:`5860`) or navigating directory history (:issue:`3550`) leading to graphical glitches have been fixed.
- The ``nim`` prompt now handles vi mode better (:issue:`6802`)
Improved terminal support
^^^^^^^^^^^^^^^^^^^^^^^^^
- A new variable, ``fish_vi_force_cursor``, can be set to force ``fish_vi_cursor`` to attempt changing the cursor
shape in vi mode, regardless of terminal (:issue:`6968`). The ``fish_vi_cursor`` option ``--force-iterm`` has been deprecated.
- ``diff`` will now colourize output, if supported (:issue:`7308`).
- Autosuggestions appear when the cursor passes the right prompt (:issue:`6948`) or wraps to the next line (:issue:`7213`).
- The cursor shape in Vi mode changes properly in Windows Terminal (:issue:`6999`, :issue:`6478`).
- The spurious warning about terminal size in small terminals has been removed (:issue:`6980`).
- Dynamic titles are now enabled in Alacritty (:issue:`7073`) and emacs' vterm (:issue:`7122`).
- Current working directory updates are enabled in foot (:issue:`7099`) and WezTerm (:issue:`7649`).
- The width computation for certain emoji agrees better with terminals (especially flags). (:issue:`7237`).
- Long command lines are wrapped in all cases, instead of sometimes being put on a new line (:issue:`5118`).
- The pager is properly rendered with long command lines selected (:issue:`2557`).
- Sessions with right prompts can be resized correctly in terminals that handle reflow, like GNOME Terminal (and other VTE-based terminals), upcoming Konsole releases and Alacritty. This detection can be overridden with the new ``fish_handle_reflow`` variable (:issue:`7491`).
- fish now sets terminal modes sooner, which stops output from appearing before the greeting and prompt are ready (:issue:`7489`).
- Better detection of new Konsole versions for true color support and cursor shape changing.
- fish no longer attempts to modify the terminal size via ``TIOCSWINSZ``, improving compatibility with Kitty (:issue:`6994`).

- Lots of improvements to completions, including:
- ``git`` completions can complete the right and left parts of a commit range like ``from..to`` or ``left...right``.
- Completion scripts for custom Git subcommands like ``git-xyz`` are now loaded with Git completions. The completions can now be defined directly on the subcommand (using ``complete git-xyz``), and completion for ``git xyz`` will work. (:issue:`7075`, :issue:`7652`, :issue:`4358`)
- ``make`` completions no longer second-guess make's file detection, fixing target completion in some cases (:issue:`7535`).
- Command completions now correctly print the description even if the command was fully matched (like in ``ls<TAB>``).
- ``set`` completions no longer hide variables starting with ``__``, they are sorted last instead.
- Improvements to the manual page completion generator (:issue:`7086`, :issue:`6879`, :issue:`7187`).
- Significant performance improvements to completion of the available commands (:issue:`7153`), especially on macOS Big Sur where there was a significant regression (:issue:`7365`, :issue:`7511`).
- Suffix completion using ``__fish_complete_suffix`` uses the same fuzzy matching logic as normal file completion, and completes any file but sorts files with matching suffix first (:issue:`7040`, :issue:`7547`). Previously, it only completed files with matching suffix.
For distributors
----------------
- fish has a new interactive test driver based on pexpect, removing the optional dependency on expect (and adding an optional dependency on pexpect) (:issue:`5451`, :issue:`6825`).
- The CHANGELOG was moved to restructured text, allowing it to be included in the documentation (:issue:`7057`).
- fish handles ncurses installed in a non-standard prefix better (:issue:`6600`, :issue:`7219`), and uses variadic tparm on NetBSD curses (:issue:`6626`).
- The Web-based configuration tool no longer uses an obsolete Angular version (:issue:`7147`).
- The fish project has adopted the Contributor Covenant code of conduct (:issue:`7151`).
Deprecations and removed features
---------------------------------
- The ``fish_color_match`` variable is no longer used. (Previously this controlled the color of matching quotes and parens when using ``read``).
- fish 3.2.0 will be the last release in which the redirection to standard error with the ``^`` character is enabled.
The ``stderr-nocaret`` feature flag will be changed to "on" in future releases.
- ``string`` is now a reserved word and cannot be used for function names (see above).
- ``fish_vi_cursor``'s option ``--force-iterm`` has been deprecated (see above).
- ``command``, ``jobs`` and ``type`` long-form option ``--quiet`` is deprecated in favor of ``--query`` (see above).
- The ``fish_command_not_found`` event is no longer emitted, instead there is a function of that name.
By default it will call a previously-defined ``__fish_command_not_found_handler``. To emit the event manually use ``emit fish_command_not_found``.
- The ``fish_prompt`` event no longer fires when ``read`` is used. If
you need a function to run any time ``read`` is invoked by a script,
use the new ``fish_read`` event instead (:issue:`7039`).
- To disable the greeting message permanently it is no longer enough to just run ``set fish_greeting`` interactively as it is
no longer implicitly a universal variable. Use ``set -U fish_greeting`` or disable it in config.fish with ``set -g fish_greeting``.
- The long-deprecated and non-functional ``-m``/``--read-mode`` options to ``read`` were removed in 3.1b1. Using the short form, or a never-implemented ``-B`` option, no longer crashes fish (:issue:`7659`).
- With the addition of new categories for debug options, the old numbered debugging levels have been removed.
For distributors and developers
-------------------------------
- fish source tarballs are now distributed using the XZ compression
method (:issue:`5460`).
- The fish source tarball contains an example FreeDesktop entry and icon.
- The CMake variable ``MAC_CODESIGN_ID`` can now be set to "off" to disable code-signing (:issue:`6952`, :issue:`6792`).
- Building on on macOS earlier than 10.13.6 succeeds, instead of failing on code-signing (:issue:`6791`).
- The pkg-config file now uses variables to ensure paths used are portable across prefixes.
- The default values for the ``extra_completionsdir``, ``extra_functionsdir``
and ``extra_confdir`` options now use the installation prefix rather than ``/usr/local`` (:issue:`6778`).
- A new CMake variable ``FISH_USE_SYSTEM_PCRE2`` controls whether fish
builds with the system-installed PCRE2, or the version it bundles. By
default it prefers the system library if available, unless Mac
codesigning is enabled (:issue:`6952`).
- Running the full interactive test suite now requires Python 3.5+ and the pexpect package (:issue:`6825`); the expect package is no longer required.
- Support for Python 2 in fish's tools (``fish_config`` and the manual page completion generator) is no longer guaranteed. Please use Python 3.5 or later (:issue:`6537`).
- The Web-based configuration tool is compatible with Python 3.10 (:issue:`7600`) and no longer requires Python's distutils package (:issue:`7514`).
- fish 3.2 is the last release to support Red Hat Enterprise Linux & CentOS version 6.
--------------
# fish 3.1.2 (released April 29, 2020)
This release of fish fixes a major issue discovered in fish 3.1.1:
- Commands such as `fzf` and `enhancd`, when used with `eval`, would hang. `eval` buffered output too aggressively, which has been fixed (#6955).
If you are upgrading from version 3.0.0 or before, please also review the release notes for 3.1.1, 3.1.0 and 3.1b1 (included below).

# fish 3.1.1 (released April 27, 2020)
This release of fish fixes a number of major issues discovered in fish 3.1.0.
- Commands which involve `. ( ... | psub)` now work correctly, as a bug in the `function --on-job-exit` option has been fixed (#6613).
- Conflicts between upstream packages for ripgrep and bat, and the fish packages, have been resolved (#5822).
- Starting fish in a directory without read access, such as via `su`, no longer crashes (#6597).
- Glob ordering changes which were introduced in 3.1.0 have been reverted, returning the order of globs to the previous state (#6593).
- Redirections using the deprecated caret syntax to a file descriptor (eg `^&2`) work correctly (#6591).
- Redirections that append to a file descriptor (eg `2>>&1`) work correctly (#6614).
- Building fish on macOS (#6602) or with new versions of GCC (#6604, #6609) is now successful.
- `time` is now correctly listed in the output of `builtin -n`, and `time --help` works correctly (#6598).
- Exported universal variables now update properly (#6612).
- `status current-command` gives the expected output when used with an environment override - that is, `F=B status current-command` returns `status` instead of `F=B` (#6635).
- `test` no longer crashes when used with "`nan`" or "`inf`" arguments, erroring out instead (#6655).
- Copying from the end of the command line no longer crashes fish (#6680).
- `read` no longer removes multiple separators when splitting a variable into a list, restoring the previous behaviour from fish 3.0 and before (#6650).
- Functions using `--on-job-exit` and `--on-process-exit` work reliably again (#6679).
- Functions using `--on-signal INT` work reliably in interactive sessions, as they did in fish 2.7 and before (#6649). These handlers have never worked in non-interactive sessions, and making them work is an ongoing process.
- Functions using `--on-variable` work reliably with variables which are set implicitly (rather than with `set`), such as "`fish_bind_mode`" and "`PWD`" (#6653).
- 256 colors are properly enabled under certain conditions that were incorrectly detected in fish 3.1.0 (`$TERM` begins with xterm, does not include "`256color`", and `$TERM_PROGRAM` is not set) (#6701).
- The Mercurial (`hg`) prompt no longer produces an error when the current working directory is removed (#6699). Also, for performance reasons it shows only basic information by default; to restore the detailed status, set `$fish_prompt_hg_show_informative_status`.
- The VCS prompt, `fish_vcs_prompt`, no longer displays Subversion (`svn`) status by default, due to the potential slowness of this operation (#6681).
- Pasting of commands has been sped up (#6713).
- Using extended Unicode characters, such as emoji, in a non-Unicode capable locale (such as the `C` or `POSIX` locale) no longer renders all output blank (#6736).
- `help` prefers to use `xdg-open`, avoiding the use of `open` on Debian systems where this command is actually `openvt` (#6739).
- Command lines starting with a space, which are not saved in history, now do not get autosuggestions. This fixes an issue with Midnight Commander integration (#6763), but may be changed in a future version.
- Copying to the clipboard no longer inserts a newline at the end of the content, matching fish 2.7 and earlier (#6927).
- `fzf` in complex pipes no longer hangs. More generally, code run as part of command substitutions or `eval` will no longer have separate process groups. (#6624, #6806).
This release also includes:
- a number of changes to improve macOS compatibility with code signing and notarization;
- a number of improvements to completions; and
- a number of content and formatting improvements to the documentation.
If you are upgrading from version 3.0.0 or before, please also review the release notes for 3.1.0 and 3.1b1 (included below).
## Errata for fish 3.1
A new builtin, `time`, was introduced in the fish 3.1 releases. This builtin is a reserved word (like `test`, `function`, and others) because of the way it is implemented, and functions can no longer be named `time`. This was not clear in the fish 3.1b1 changelog.
From Jonathan Schleifer in PR pkg/54965,
lightly changed by myself for netbsd support.
fish 3.1.0 (released February 12, 2020)
Compared to the beta release of fish 3.1b1, fish version 3.1.0:
* fixes a regression where spaces after a brace were removed despite
brace expansion not occurring (#6564)
* fixes a number of problems in compiling and testing on Cygwin (#6549)
and Solaris-derived systems such as Illumos (#6553, #6554, #6555,
#6556, and #6558);
* fixes the process for building macOS packages;
* fixes a regression where excessive error messages are printed if
Unicode characters are emitted in non-Unicode-capable locales
(#6584); and
* contains some improvements to the documentation and a small number of
completions.
If you are upgrading from version 3.0.0 or before, please also review
the release notes for 3.1b1 (included below).
Release notes for fish 3.1b1 (released January 26, 2020)
Notable improvements and fixes
* A new $pipestatus variable contains a list of exit statuses of the
previous job, for each of the separate commands in a pipeline
(#5632).
* fish no longer buffers pipes to the last function in a pipeline,
improving many cases where pipes appeared to block or hang (#1396).
* An overhaul of error messages for builtin commands, including a
removal of the overwhelming usage summary, more readable stack traces
(#3404, #5434), and stack traces for test (aka [) (#5771).
* fish's debugging arguments have been significantly improved. The
--debug-level option has been removed, and a new --debug option
replaces it. This option accepts various categories, which may be listed
via fish --print-debug-categories (#5879). A new --debug-output option
allows for redirection of debug output.
* string has a new collect subcommand for use in command substitutions,
producing a single output instead of splitting on new lines (similar
to "$(cmd)" in other shells) (#159).
* The fish manual, tutorial and FAQ are now available in man format as
fish-doc, fish-tutorial and fish-faq respectively (#5521).
* Like other shells, cd now always looks for its argument in the
current directory as a last resort, even if the CDPATH variable does
not include it or "." (#4484).
* fish now correctly handles CDPATH entries that start with .. (#6220)
or contain ./ (#5887).
* The fish_trace variable may be set to trace execution (#3427). This
performs a similar role as set -x in other shells.
* fish uses the temporary directory determined by the system, rather
than relying on /tmp (#3845).
* The fish Web configuration tool (fish_config) prints a list of
commands it is executing, to help understanding and debugging
(#5584).
* Major performance improvements when pasting (#5866), executing lots
of commands (#5905), importing history from bash (#6295), and when
completing variables that might match $history (#6288).
Syntax changes and new commands
* A new builtin command, time, which allows timing of fish functions
and builtins as well as external commands (#117).
* Brace expansion now only takes place if the braces include a "," or a
variable expansion, meaning common commands such as git reset
HEAD@{0} do not require escaping (#5869).
* New redirections &> and &| may be used to redirect or pipe stdout,
and also redirect stderr to stdout (#6192).
* switch now allows arguments that expand to nothing, like empty
variables (#5677).
* The VAR=val cmd syntax can now be used to run a command in a modified
environment (#6287).
* and is no longer recognised as a command, so that nonsensical
constructs like and and and produce a syntax error (#6089).
* math's exponent operator, '^', was previously left-associative, but
now uses the more commonly-used right-associative behaviour (#6280).
This means that math '3^0.5^2' was previously calculated as
'(3^0.5)^2', but is now calculated as '3^(0.5^2)'.
* In fish 3.0, the variable used with for loops inside command
substitutions could leak into enclosing scopes; this was an
inadvertent behaviour change and has been reverted (#6480).
Scripting improvements
* string split0 now returns 0 if it split something (#5701).
* In the interest of consistency, builtin -q and command -q can now be
used to query if a builtin or command exists (#5631).
* math now accepts --scale=max for the maximum scale (#5579).
* builtin $var now works correctly, allowing a variable as the builtin
name (#5639).
* cd understands the -- argument to make it possible to change to
directories starting with a hyphen (#6071).
* complete --do-complete now also does fuzzy matches (#5467).
* complete --do-complete can be used inside completions, allowing
limited recursion (#3474).
* count now also counts lines fed on standard input (#5744).
* eval produces an exit status of 0 when given no arguments, like other
shells (#5692).
* printf prints what it can when input hasn't been fully converted to a
number, but still prints an error (#5532).
* complete -C foo now works as expected, rather than requiring complete
-Cfoo.
* complete has a new --force-files option, to re-enable file
completions. This allows sudo -E and pacman -Qo to complete correctly
(#5646).
* argparse now defaults to showing the current function name (instead
of argparse) in its errors, making --name often superfluous (#5835).
* argparse has a new --ignore-unknown option to keep unrecognized
options, allowing multiple argparse passes to parse options (#5367).
* argparse correctly handles flag value validation of options that only
have short names (#5864).
* read -S (short option of --shell) is recognised correctly (#5660).
* read understands --list, which acts like --array in reading all
arguments into a list inside a single variable, but is better named
(#5846).
* read has a new option, --tokenize, which splits a string into
variables according to the shell's tokenization rules, considering
quoting, escaping, and so on (#3823).
* read interacts more correctly with the deprecated $IFS variable, in
particular removing multiple separators when splitting a variable
into a list (#6406), matching other shells.
* fish_indent now handles semicolons better, including leaving them in
place for ; and and ; or instead of breaking the line (#5859).
* fish_indent --write now supports multiple file arguments, indenting
them in turn.
* The default read limit has been increased to 100MiB (#5267).
* math now also understands x for multiplication, provided it is
followed by whitespace (#5906).
* math reports the right error when incorrect syntax is used inside
parentheses (#6063), and warns when unsupported logical operations
are used (#6096).
* functions --erase now also prevents fish from autoloading a function
for the first time (#5951).
* jobs --last returns 0 to indicate success when a job is found
(#6104).
* commandline -p and commandline -j now split on && and || in addition
to ; and & (#6214).
* A bug where string split would drop empty strings if the output was
only empty strings has been fixed (#5987).
* eval no long creates a new local variable scope, but affects
variables in the scope it is called from (#4443). source still
creates a new local scope.
* abbr has a new --query option to check for the existence of an
abbreviation.
* Local values for fish_complete_path and fish_function_path are now
ignored; only their global values are respected.
* Syntax error reports now display a marker in the correct position
(#5812).
* Empty universal variables may now be exported (#5992).
* Exported universal variables are no longer imported into the global
scope, preventing shadowing. This makes it easier to change such
variables for all fish sessions and avoids breakage when the value is
a list of multiple elements (#5258).
* A bug where for could use invalid variable names has been fixed
(#5800).
* A bug where local variables would not be exported to functions has
been fixed (#6153).
* The null command (:) now always exits successfully, rather than
passing through the previous exit status (#6022).
* The output of functions FUNCTION matches the declaration of the
function, correctly including comments or blank lines (#5285), and
correctly includes any --wraps flags (#1625).
* type supports a new option, --short, which suppress function
expansion (#6403).
* type --path with a function argument will now output the path to the
file containing the definition of that function, if it exists.
* type --force-path with an argument that cannot be found now correctly
outputs nothing, as documented (#6411).
* The $hostname variable is no longer truncated to 32 characters
(#5758).
* Line numbers in function backtraces are calculated correctly (#6350).
* A new fish_cancel event is emitted when the command line is
cancelled, which is useful for terminal integration (#5973).
Interactive improvements
* New Base16 color options are available through the Web-based
configuration (#6504).
* fish only parses /etc/paths on macOS in login shells, matching the
bash implementation (#5637) and avoiding changes to path ordering in
child shells (#5456). It now ignores blank lines like the bash
implementation (#5809).
* The locale is now reloaded when the LOCPATH variable is changed
(#5815).
* read no longer keeps a history, making it suitable for operations
that shouldn't end up there, like password entry (#5904).
* dirh outputs its stack in the correct order (#5477), and behaves as
documented when universal variables are used for its stack (#5797).
* funced and the edit-commandline-in-buffer bindings did not work in
fish 3.0 when the $EDITOR variable contained spaces; this has been
corrected (#5625).
* Builtins now pipe their help output to a pager automatically (#6227).
* set_color now colors the --print-colors output in the matching colors
if it is going to a terminal.
* fish now underlines every valid entered path instead of just the last
one (#5872).
* When syntax highlighting a string with an unclosed quote, only the
quote itself will be shown as an error, instead of the whole
argument.
* Syntax highlighting works correctly with variables as commands
(#5658) and redirections to close file descriptors (#6092).
* help works properly on Windows Subsytem for Linux (#5759, #6338).
* A bug where disown could crash the shell has been fixed (#5720).
* fish will not autosuggest files ending with ~ unless there are no
other candidates, as these are generally backup files (#985).
* Escape in the pager works correctly (#5818).
* Key bindings that call fg no longer leave the terminal in a broken
state (#2114).
* Brackets (#5831) and filenames containing $ (#6060) are completed
with appropriate escaping.
* The output of complete and functions is now colorized in interactive
terminals.
* The Web-based configuration handles aliases that include single
quotes correctly (#6120), and launches correctly under Termux (#6248)
and OpenBSD (#6522).
* function now correctly validates parameters for --argument-names as
valid variable names (#6147) and correctly parses options following
--argument-names, as in "--argument-names foo --description bar"
(#6186).
* History newly imported from bash includes command lines using && or
||.
* The automatic generation of completions from manual pages is better
described in job and process listings, and no longer produces a
warning when exiting fish (#6269).
* In private mode, setting $fish_greeting to an empty string before
starting the private session will prevent the warning about history
not being saved from being printed (#6299).
* In the interactive editor, a line break (Enter) inside unclosed
brackets will insert a new line, rather than executing the command
and producing an error (#6316).
* Ctrl-C always repaints the prompt (#6394).
* When run interactively from another program (such as Python), fish
will correctly start a new process group, like other shells (#5909).
* Job identifiers (for example, for background jobs) are assigned more
logically (#6053).
* A bug where history would appear truncated if an empty command was
executed was fixed (#6032).
New or improved bindings
* Pasting strips leading spaces to avoid pasted commands being omitted
from the history (#4327).
* Shift-Left and Shift-Right now default to moving backwards and
forwards by one bigword (words separated by whitespace) (#1505).
* The default escape delay (to differentiate between the escape key and
an alt-combination) has been reduced to 30ms, down from 300ms for the
default mode and 100ms for Vi mode (#3904).
* The forward-bigword binding now interacts correctly with
autosuggestions (#5336).
* The fish_clipboard_* functions support Wayland by using
[wl-clipboard](https://github.com/bugaevc/wl-clipboard) (#5450).
* The nextd and prevd functions no longer print "Hit end of history",
instead using a bell. They correctly store working directories
containing symbolic links (#6395).
* If a fish_mode_prompt function exists, Vi mode will only execute it
on mode-switch instead of the entire prompt. This should make it much
more responsive with slow prompts (#5783).
* The path-component bindings (like Ctrl-w) now also stop at ":" and
"@", because those are used to denote user and host in commands such
as ssh (#5841).
* The NULL character can now be bound via bind -k nul. Terminals often
generate this character via control-space. (#3189).
* A new readline command expand-abbr can be used to trigger
abbreviation expansion (#5762).
* A new readline command, delete-or-exit, removes a character to the
right of the cursor or exits the shell if the command line is empty
(moving this functionality out of the delete-or-exit function).
* The self-insert readline command will now insert the binding
sequence, if not empty.
* A new binding to prepend sudo, bound to Alt-S by default (#6140).
* The Alt-W binding to describe a command should now work better with
multiline prompts (#6110)
* The Alt-H binding to open a command's man page now tries to ignore
sudo (#6122).
* A new pair of bind functions, history-prefix-search-backward (and
forward), was introduced (#6143).
* Vi mode now supports R to enter replace mode (#6342), and d0 to
delete the current line (#6292).
* In Vi mode, hitting Enter in replace-one mode no longer erases the
prompt (#6298).
* Selections in Vi mode are inclusive, matching the actual behaviour of
Vi (#5770).
Improved prompts
* The Git prompt in informative mode now shows the number of stashes if
enabled.
* The Git prompt now has an option
($__fish_git_prompt_use_informative_chars) to use the (more modern)
informative characters without enabling informative mode.
* The default prompt now also features VCS integration and will color
the host if running via SSH (#6375).
* The default and example prompts print the pipe status if an earlier
command in the pipe fails.
* The default and example prompts try to resolve exit statuses to
signal names when appropriate.
Improved terminal output
* New fish_pager_color_ options have been added to control more
elements of the pager's colors (#5524).
* Better detection and support for using fish from various system
consoles, where limited colors and special characters are supported
(#5552).
* fish now tries to guess if the system supports Unicode 9 (and
displays emoji as wide), eliminating the need to set
$fish_emoji_width in most cases (#5722).
* Improvements to the display of wide characters, particularly Korean
characters and emoji (#5583, #5729).
* The Vi mode cursor is correctly redrawn when regaining focus under
terminals that report focus (eg tmux) (#4788).
* Variables that control background colors (such as
fish_pager_color_search_match) can now use --reverse.
Completions
* Added completions for
* aws
* bat (#6052)
* bosh (#5700)
* btrfs
* camcontrol
* cf (#5700)
* chronyc (#6496)

* vbc (#6016)
* zpaq (#6245)
* zstd, zstdcat, zstdgrep, zstdless and zstdmt (#6364)
* Lots of improvements to completions.
* Selecting short options which also have a long name from the
completion pager is possible (#5634).
* Tab completion will no longer add trailing spaces if they already
exist (#6107).
* Completion of subcommands to builtins like and or not now works
correctly (#6249).
* Completion of arguments to short options works correctly when
multiple short options are used together (#332).
* Activating completion in the middle of an invalid completion does not
move the cursor any more, making it easier to fix a mistake (#4124).
* Completion in empty commandlines now lists all available commands.
* Functions listed as completions could previously leak parts of the
function as other completions; this has been fixed.
Deprecations and removed features
* The vcs-prompt functions have been promoted to names without
double-underscore, so __fish_git_prompt is now fish_git_prompt,
__fish_vcs_prompt is now fish_vcs_prompt, __fish_hg_prompt is now
fish_hg_prompt and __fish_svn_prompt is now fish_svn_prompt. Shims at
the old names have been added, and the variables have kept their old
names (#5586).
* string replace has an additional round of escaping in the replacement
expression, so escaping backslashes requires many escapes (eg string
replace -ra '([ab])' '\\\\\\\$1' a). The new feature flag
regex-easyesc can be used to disable this, so that the same effect
can be achieved with string replace -ra '([ab])' '\\\\$1' a (#5556).
As a reminder, the intention behind feature flags is that this will
eventually become the default and then only option, so scripts should
be updated.
* The fish_vi_mode function, deprecated in fish 2.3, has been removed.
Use fish_vi_key_bindings instead (#6372).
For distributors and developers
* fish 3.0 introduced a CMake-based build system. In fish 3.1, both the
Autotools-based build and legacy Xcode build system have been
removed, leaving only the CMake build system. All distributors and
developers must install CMake.
* fish now depends on the common tee external command, for the psub
process substitution function.
* The documentation is now built with Sphinx. The old Doxygen-based
documentation system has been removed. Developers, and distributors
who wish to rebuild the documentation, must install Sphinx.
* The INTERNAL_WCWIDTH build option has been removed, as fish now
always uses an internal wcwidth function. It has a number of
configuration options that make it more suitable for general use
(#5777).
* mandoc can now be used to format the output from --help if nroff is
not installed, reducing the number of external dependencies on
systems with mandoc installed (#5489).
* Some bugs preventing building on Solaris-derived systems such as
Illumos were fixed (#5458, #5461, #5611).
* Completions for npm, bower and yarn no longer require the jq utility
for full functionality, but will use Python instead if it is
available.
* The paths for completions, functions and configuration snippets have
been extended. On systems that define XDG_DATA_DIRS, each of the
directories in this variable are searched in the subdirectories
fish/vendor_completions.d, fish/vendor_functions.d, and
fish/vendor_conf.d respectively. On systems that do not define this
variable in the environment, the vendor directories are searched for
in both the installation prefix and the default "extra" directory,
which now defaults to /usr/local (#5029).
# fish 3.0.2 (released February 19, 2019)
This release of fish fixes an issue discovered in fish 3.0.1.
### Fixes and improvements
- The PWD environment variable is now ignored if it does not resolve to the true working directory, fixing strange behaviour in terminals started by editors and IDEs (#5647).
If you are upgrading from version 2.7.1 or before, please also review the release notes for 3.0.1, 3.0.0 and 3.0b1 (included below).

# fish 3.0.1 (released February 11, 2019)
This release of fish fixes a number of major issues discovered in fish 3.0.0.
### Fixes and improvements
- `exec` does not complain about running foreground jobs when called (#5449).
- while loops now evaluate to the last executed command in the loop body (or zero if the body was empty), matching POSIX semantics (#4982).
- `read --silent` no longer echoes to the tty when run from a non-interactive script (#5519).
- On macOS, path entries with spaces in `/etc/paths` and `/etc/paths.d` now correctly set path entries with spaces. Likewise, `MANPATH` is correctly set from `/etc/manpaths` and `/etc/manpaths.d` (#5481).
- fish starts correctly under Cygwin/MSYS2 (#5426).
- The `pager-toggle-search` binding (Ctrl-S by default) will now activate the search field, even when the pager is not focused.
- The error when a command is not found is now printed a single time, instead of once per argument (#5588).
- Fixes and improvements to the git completions, including printing correct paths with older git versions, fuzzy matching again, reducing unnecessary offers of root paths (starting with `:/`) (#5578, #5574, #5476), and ignoring shell aliases, so enterprising users can set up the wrapping command (via `set -g __fish_git_alias_$command $whatitwraps`) (#5412).
- Significant performance improvements to core shell functions (#5447) and to the `kill` completions (#5541).
- Starting in symbolically-linked working directories works correctly (#5525).
- The default `fish_title` function no longer contains extra spaces (#5517).
- The `nim` prompt now works correctly when chosen in the Web-based configuration (#5490).
- `string` now prints help to stdout, like other builtins (#5495).
- Killing the terminal while fish is in vi normal mode will no longer send it spinning and eating CPU. (#5528)
- A number of crashes have been fixed (#5550, #5548, #5479, #5453).
- Improvements to the documentation and certain completions.
### Known issues
There is one significant known issue that was not corrected before the release:
- fish does not run correctly under Windows Services for Linux before Windows 10 version 1809/17763, and the message warning of this may not be displayed (#5619).
If you are upgrading from version 2.7.1 or before, please also review the release notes for 3.0.0 and 3.0b1 (included below).
if MANPATH is empty but the environment variable is respected, we won't
be able to find any man pages, because fish set it to PREFIX/share/fish/man
bump PKGREVISION
Add a "doc" option, default on, to avoid a doxygen dependency.

# 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)
- `hjson`
- `hugo` (#4529)
- `j` (from autojump #4344)
- `jbake` (#4814)
- `jhipster` (#4472)
- `kitty`
- `kldload`
- `kldunload`
- `makensis` (#5242)
- `meson`
- `mkdocs` (#4906)
- `ngrok` (#4642)
- OpenBSD's `pkg_add`, `pkg_delete`, `pkg_info`, `pfctl`, `rcctl`, `signify`, and `vmctl` (#4584)
- `openocd`
- `optipng`
- `opkg` (#5168)
- `pandoc` (#2937)
- `port` (#4737)
- `powerpill` (#4800)
- `pstack` (#5135)
- `serve` (#5026)
- `ttx`
- `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.
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)

- Sublime Text 3's `subl` (#4277)
- Lots of improvements to completions.
- Updated Chinese and French translations.
don't mess with the declaration of tparm_solaris_kludge unnecessarily.
uwe thinks the non-variadic tparm is wrong (so might be broken for
solaris curses), but I'm not sure how to correct it.

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.

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)

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)
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).
Existing SHA1 digests verified, all found to be the same on the
machine holding the existing distfiles (morden). Existing SHA1
digests retained for now as an audit trail.

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.
