For usage in completion scripts.
Unlike `__fish_is_first_token` (which is probably not correctly named),
`__fish_is_first_arg` returns true regardless of whether existing tokens start with `-`
or not, to be used when an arg cannot be used with any other argument.
`__fish_prev_arg_in` is similar to `__fish_seen_...` but it explicitly
tests the preceding token only, for arguments that take only a single
parameter.
As it turns out, for some terminals backspace is \b but only when
preceded by \e.
All this makes about as much sense as the english language.
Fixes#4955.
The previous completion generation was broken for several reasons:
* ./foo would break detection of suffix due to the leading . being
interpreted an extension marker,
* ./foo would be completed as foo, which would be excluded from
matching inrcomplete.cpp
Using `git for-each-ref` both simplifies the code (no need to deal
with detached heads anymore) and speeds it up.
With 1600 branches, the time goes from ~48ms to ~16ms.
- fix capitalization
- shorten descriptions
- implement subcommand shortcuts
- add arg completion for 'limit' and 'depth' switches
- improve arg completion for list subcommand in case of -p switch
bower was calling `__fish_should_complete_args`, the old name for
`__fish_should_complete_switches.`
yarn was parsing bower.json instead of package.json.
To be used by completions to directly determine whether it is either
possible or preferable to complete a switch (instead of a subcommand),
(presuming that switches must come before subcommands).
* __fish_can_complete_switches: we are in a position where a switch may
be placed.
* __fish_should_complete_switches: we're in a position to accept a
switch and the current token starts with `-` so we have no choice but
to do so.

`all-the-package-names` is still used to generate completions for `npm`
if it is installed, but it is not manually installed nor updated. It is
now the user's responsibility to do both, and it must be installed
globally.
`npm search` was _way_ too slow to be used for dynamic completions, so
using a cached list of all avaialable NPM packages to match against.
This is a bit brave for a fish completion, but the npm package
`all-the-package-names` has a list of, well, all the package names
avaialable for installation via the default npm registry. Installing a
copy locally to $HOME/.cache/fish/npm_completions and using that to
search for packages matching the tokenized command line.
Preference would be to call `__update_atpm` in the background, but that
emits an ugly "job has completed" message..
Should also use this for completions for `yarn add`.
Instead, attempt to extract the message that _would_ be displayed on
execution of `./configure --help` by relying on some markers present in
autoconf-generated configure files.
As measured with 'hyperfine' on a laptop running in reduced frequency
power savings mode, `fish -c "__fish_parse_configure ./configure"`
runtime dropped from ~1.25s to ~0.8ms, which is inline with the
previously observed ~350ms execution time for `./configure --help`.
fish's own startup time is approximately 75ms before parsing begins.
Still very slow, but much better.
This relies on the new `read --line/-L` support as an entire parser for
the output of `./configure --help` was written in fishscript. Also
doesn't work without 72f32e6d8a7905b064680ec4b578c41dea62bf84.
The completion script is slow... a function of both the autotools
configure script itself being written in a shell script combined with a
fishscript output parser.
fish's own `./configure --help` takes around 350ms to execute, while
`__fish_parse_configure ./configure` (which runs that behind the scenes)
takes around 660ms to run, all-in-all - a not insignificant overhead.
Output can be cached (based off of ./configure hash or mtime) in the
future if this is a big deal.
The default completions that autojump ships with for fish are broken
(emitting output like "1\___\#...") as they use hackes to work around
the previous lack of `complete -k`. The history-based autojump
completions fully replace it.
The job expansion wrapper was swallowing `-n` (and presumably `-e` and
others) when that was the literal argument we needed to emit. Using
`printf %s ...` instead.
Now the description includes the variable scope, `set [-e] -[Ugl]`
completions only provide variables matching that scope, and completions
that shouldn't be modified are hidden from the user. Completions that
are often modified but rarely unset (`fish_*` variables) are omitted
from `set -e` completions.
A new helper function `__fish_seen_argument` has been added that makes
it easy to only provied completions for a specific flag.
Launch `cmd.exe /c "start URL"` under WSL for both `fish_config` and
`help`. This works around #4299 but does not address the underlying
issue (#1132).
fish reads paths out of /etc/paths.d. Prior to adbaddf it did
this on every shell invocation; with adbaddf it does so on only login
shells. This change wasn't justified so let's revert this behavior.
(and /etc/paths.d/*)
Do so by emulating the behavior of /usr/libexec/path_helper for login
shells, matching the behavior in /etc/profile.
Also add a path_helper command to reproduce the behavior of
/usr/libexec/path_helper for fish.
This also handles setting MANPATH if necessary.
Fixes issue #4336
* Completion for conda, the package manager
* Make the list of platforms a private variable
* Add commands activate and deactivate
* Avoid clobbering a user-defined function __
* Use Use __fish_seen_subcommand_from to identify subcommand
And treat the case of the first argument as a special case
with function __fish_conda_fist_arg
* Factor out create from loop for option --name
* Fix typo (missing parenthesis in description)
* Start from a blank state by removing completions from conda configuration script
no-op function for compatibility with sh, bash, and others.
Often used to insert a comment into a chain of commands without having
it eat up the remainder of the line, handy in Makefiles.
- Cache translations instead of calling `gettext` once per file
- Only do the ":/" thing if the file isn't in $PWD/**
For a git repo created like
```fish
git init
touch a(seq 0 1000)b
```
this changes the time from about 2s to 0.3s.
`git rm --cached` is often used to delete a file that no longer exists
in the working tree but remains in git's index. `git ls-files` will list
files that are in the HEAD, which is exactly what we want. Local files
not in `HEAD` can't be deleted from git anyway.
The tool subcommand had a "-f" flag to disallow file completions which is wrong: most of the tools there require a file/directory argument.
Since we're here, also limit "go tool compile" to only match Go source files.
In similar vein to how fish_default_key_bindings works, parameters
passed to the function are automatically passed to bind upstream.
Additionally, -s is automatically added if no parameters had been
specified to prevent startup error messages. See 46d1334.
Closes#4494
Drops the % notation for process expansion. The existing notation was a
mess and expanded jobs, process ids, and process names via dark magic.
With this change, % is no longer a special character and can be used
unescaped with impunity.
The variables %self and %last, referring to fish's own pid and the pid
of the last backgrounded job respectively, have been replaced with $pid
and $last_pid. These are read-only variables, protected against being
redefined by the user.
Author's note: I would have personally preferred $fish_pid instead of
$pid but since we debated changing $version to $fish_version and then
reverted that change (with much acrimony), it makes no sense to break
with that precedent here. Additionally, $fish_last_pid is quite wordy.
Closes#4230. Closes#1202.
