./shells/fish, User friendly command line shell for UNIX-like operating systems

[ CVSweb ] [ Homepage ] [ RSS ] [ Required by ] [ Add to tracker ]

Branch: CURRENT, Version: 3.0.0nb2, Package name: fish-3.0.0nb2, Maintainer: pkgsrc-users

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.

# 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 \ 

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 \ 

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 \ 
- 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 `$hostname` \ 
reserved variable. This removes the dependency on the `hostname` executable \ 
- Bare `bind` invocations in config.fish now work. The `fish_user_key_bindings` \ 
function is no longer necessary, but will still be executed if it exists \ 
- `$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 \ 
- `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 \ 
- `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 \ 
- 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 \ 
- 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 \ 
- 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 \ 
- 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 \ 
- 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 \ 
- The `hostname` command is no longer required for fish to operate.

fish: update to 2.7.1

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 \ 

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 \ 
- `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 \ 

## Other significant changes
- The `COLUMNS` and `LINES` environment variables are now correctly set the \ 
first time `fish_prompt` is run (#4141).
- `complete`'s `--no-files` option works as intended (#112).
- `echo -h` now correctly echoes `-h` in line with other shells (#4120).
- The `export` compatibility function now returns zero on success, rather than \ 
always returning 1 (#4435).
- Stop converting empty elements in MANPATH to "." (#4158). The \ 
behavior being changed was introduced in fish 2.6.0.
- `count -h` and `count --help` now return 1 rather than produce command help \ 
output (#4189).
- An attempt to `read` which stops because too much data is available still \ 
defines the variables given as parameters (#4180).
- A regression in fish 2.4.0 which prevented `pushd +1` from working has been \ 
fixed (#4091).
- A regression in fish 2.6.0 where multiple `read` commands in non-interactive \ 
scripts were broken has been fixed (#4206).
- A regression in fish 2.6.0 involving universal variables with side-effects at \ 
startup such as `set -U fish_escape_delay_ms 10` has been fixed (#4196).
- Added completions for:
  - `as` (#4130)
  - `cdh` (#2847)
  - `dhcpd` (#4115)
  - `ezjail-admin` (#4324)
  - Fabric's `fab` (#4153)
  - `grub-file` (#4119)
  - `grub-install` (#4119)
  - `jest` (#4142)
  - `kdeconnect-cli`
  - `magneto` (#4043, #4108)
  - `mdadm` (#4198)
  - `passwd` (#4209)
  - `pip` and `pipenv` (#4448)
  - `s3cmd` (#4332)
  - `sbt` (#4347)
  - `snap` (#4215)
  - Sublime Text 3's `subl` (#4277)
- Lots of improvements to completions.
- Updated Chinese and French translations.
