GNU ls's --indicator-style=classify is the same as POSIX -F.
Refactor and change command testing logic so that we define the
function in the same place for all platforms, and use -F on all
the platforms when stdout is a TTY.
A person stuck installing it just for fish on their server
doesn't want to waste time installing the wrong one, so assuage that.
Also tweak to look nicer with 80 columns
As discussed in #5492, it would be good if running fish_config without
Python actually told the user to install Python.
Further, let's give the person some hints on how to configure these
things by hand, since they may have to.
Which is 4, apparently.. (builtin_set.cpp returns ENV_NOT_FOUND)
here. This was previously hardcoded to our 121, which used to be
what builtins used for invalid arguments.
4 is pretty arbitrary but at least this is more consistent.
I had previously introduced a lot of updates and fixes to npm registry
based completions for `yarn` but hadn't ported them to `npm` as well
(although they can be dropped in as-is). This patch shares the code
between the two, which resides in an explicitly sourced multi-function
fish script.
* Severely extended the sorin theme
This theme should now mostly match the original.
* Removed superfluous whitespace
* Inlined external links as ASCII art
* Made myself the author of the sorin theme
* Removed superfluous read delemiter
* Renamed __fish_git_action to fish_print_git_action
* Adde a minor comment
Cleaned up the code to no longer replicate in fishscript what fish
already does (and caches to boot) in C++ in setting up the paths to the
user configuration directory.
Also introduced a `$__fish_user_data_dir` instead of the sporadic
definitions of `$userdatadir` that may or may not go through
`XDG_DATA_HOME`.
I spent some time figuring out $TERM_PROGRAM_VERSION and Terminal.app's
capabilities over time. [1]
Only use OSC 7 if running on the version of Terminal.app that added it
or newer. In the past this would have been harder because `test` couldn't
do float comparisons.
cleanup:
Don't bother setting a local $TERM_PROGRAM if it's unset: quoting
is enough to keep test happy. For the version numbers, 0"$var" is safe
against unset variables for numerical comparisons.

Instead of maybe adding "-s" and "-M" if "-s" hasn't already been
given, just add "-s" to _every_ bind invocation, and "-M" to those who
need it.
Fixes#5028.
Largely reverts 007d794b6e.
fish_indent is extremely resource-intensive on large inputs and can crash; it also does not handle
invalid characters gracefully.
Work on #5402.
man.fish can be clarified a bit, by removing a superfluous early return. Additionally, performance can be
(ever so slightly) improved, by using the empty string to suffix an extra colon when `$MANPATH` is empty, as
described in `manpath(1)`. As `man` will internally call `manpath` as it starts, this eliminates a redundancy.
- No longer uses sed, sort, uniq, uname
- Stop doing too-clever filtering (e.g. the kernel thread stuff never
- really worked)
- Don't truncate for all OSen, instead just use the (correctly
- truncated) comm field.
- Colorize history search output when interactive, using
fish_indent. This is the same way we colorize `type` output.
- Ask less to act like `cat` if the output will fit in the
terminal window, so it's less jaring with short output.
- history is viewed in a pager when interactive, but pagers
typically strip escape codes. We accomplish the above by
doing exactly what `git` does[1] when it has colored output
for a pager:
if $LESS is unset, set it to enable -R, -F, and -X options.
if $LV is unset, set it to -c.

Fixes some potentially unsafe uses of direct substitution into regex
expressions and also switches some completions to regex-based now that
there is a safe way of using it.
In writing the completion script for openocd I found the need to
complete paths at the command-line as if they were relative to a
path other than the current $PWD. Given that `$PWD` is currently
global in fish (i.e. no side-effect free `cd` within a subshell)
this is probably good to have for other completions too.
This also fixes a bug in support for explicitly supplying the
description for completions via a `$argv` parameter, which prefixed
the description with `\t` (which is correct) except it did so in
the local scope within an `if` statement, meaning the changes never
had any effect and in the output the description was directly
concatenated to the completions, instead of separated by a tab.
Don't attempt to complete against package names if the user is trying to
enter a switch to speed things up.
Also work around #5267 by not wrapping unfiltered `all-the-package-name`
calls in a function.
We do a bunch of escaping before to make `eval` work, and that needs to be removed as well or fragment-urls don't work.
This reverts commit e9568069a7.
Use clang/clang++'s own autocompletion support to complete arguments. It
is rather convoluted as clang generates autocompletions for a portion of
the current token rather than the entire token, e.g. while `--st` will
autocomplete to `--std=` (which is fine by fish), `--std=g` will
autocomplete to `gnu...` without the leading `--std=` which breaks fish'
support for the completion.
Additionally, on systems where clang/clang++ is the system compiler
(such as FreeBSD), it is very often for users to invoke a newer version
of clang/clang++ installed as clang[++]-NN instead of clang. Using a
monkey-patched version of `complete -p` to support that without breaking
(future) completions for commands like `clang-format`.
Closes#4174.
If you're using the old binding that only clears the commandline and
doesn't preserve its contents and start a new line, you can use
```fish
bind \cc "commandline -f cancel; commandline ''"
```
instead.
Closes#4298.
For some weird reason we only used $editor if it wasn't empty, but
then failed to fail if it was.
This will now print an error and use fish, just like if the $EDITOR
value is invalid in any other way.
Fixes#5257.
The hg prompt walks up the directory hierarchy to decide if we are in a
repo subdirectory. Because hg is an external command, it resolves symlinks.
Switch to using pwd -P so hg and fish will have the same view of the hg repo.
Based on comment:
https://github.com/fish-shell/fish-shell/pull/5190#issuecomment-421912360
This allows for marking certain bindings as part of a preset, which allows us to
- only erase those when switching presets
- go back to the preset binding when erasing a user binding
- only show user customization if requested
- make bare bind statements in config.fish work (!!!11elf!!!)
Fixes#5191.
Fixes#3699.
- Add support for:
- Jumping to the character before a target.
- Repeating the previous jump (same direction, same precision).
- Repeating the previous jump in the reverse order.
- Enhance vi bindings.
Ordering of directories above files was introduced in a recent change to
the same script. By default it does not matter as completions are sorted
by fish internally, but this allows the use of `-k` to sort files before
directories (or piped to `sort -r` for vice-versa).
Use `apt-cache show` instead of `apt-cache packagenames` to efficiently
print package names and a brief description instead of the placeholder
(localized) "Package" text that was previously printed. This applies to
both available and installed packages (for inistall and remove operations,
respectively).
TODO: update `__fish_print_packages` for non-debian platforms to do the
same.
When listing packages already installed (e.g. for use with `apt remove
...`), do not consider packages return by `dpkg --get-selections` with
state 'deinstall'.
Previously the `string replace` pattern was matching both 'install' and
'deinstall' packages.
Utilized the `--install` flag added in commit #8c09d6e.
Limit `eopkg remove/autoremove/check ...` completions to installed packages.
Limit `eopkg install/upgrade/info ...` completions to available packages.
Prior to this fix, __fish_describe_command would error if the
input contained any special characters, because it would be interpolated
into a regex. Hack in a guard to do nothing if the input contains
anything other than [a-zA-Z0-9_ ]
Added a new flag `--installed` via `argparse` to `__fish_print_packages`
which indicates that only installed packages should be listed.
TODO: Other non-debian/apt platforms should take advantage of this flag/
behavior as well.
Executes `whatis` safely, returns at most one line, and strips the name
of the command from the start of line, returning a value fit for use as
the description parameter for a completion argument value.
Fixes
- Use the actual path when skipping unusable paths to fix all Include
directives being skipped when there is no ~/.ssh directory
- Prevent "No matches for wildcard" message
Improvements
- Skip paths that are directories since we only want files
- Remove `cd` as it is not needed
__fish_complete_suffix assumed that the only literal . in a path
would be the . before an extension, and stripped accordingly. This
behavior has been there for a long time, but broke many things
including completion of relative paths and completion of paths with
a literal . in a directory name.
__fish_complete_suffix does not just complete extensions (or at the
very least, it no longer does just that) but rather any suffix, so
isolating the path name without the extension was unnecessary in all
cases.
With a blank $suff (i.e. complete all files), __fish_complete_suffix
returned directories twice, once with the trailing `/` and once without.
This fixes that, and additionally speeds up the code by no longer
shelling out to `sort -u` as we no longer rely on brace expansion to
enumerate directories and files simultaneously.
In general, this behavior would occur when a directory exists that
matches the suffix search pattern (so a dir named 'foo.bar' with a
search pattern '.bar' would return 'foo.bar' twice).
Runtime has dropped from ~22ms to ~8ms on my machine, while also
returning more correct results.
This prints an escape sequence, so it can break scp or similar when
someone has an unqualified
fish_vi_key_bindings
in config.fish and happens to run a terminal that can set the cursor.
Under FreeBSD, as annoying as it is, switches must directly follow the
command or subcommand in question, and cannot come after actual payload
argument. Calling `zpool get all -H` instead of `zpool get -H all`
caused error messages to be spewed to the console under FreeBSD when
simply completing `zfs <TAB>`, this should fix that. The change should
also be compatible with other operating systems (namely Linux) that
don't have this requirement, as they (generally) allow arguments to come
before _or_ after the primary non-switch argument (though I do not have
access to a zfs-enabled Linux machine to test this).
Previously, trying to complete a token with any of these
expansion-related characters would cause the completion to return no
results, as it would emit expanded values which weren't matched by the
autocompleter.
Akin to __fish_complete_suffix, __fish_complete_directories now attempts
to complete the current commandline token if no token is explicitly
passed in as an argument.
The prompt is a fallback that is overridden via a function file
anyway.
Do that with the title as well, so we can use just builtins.
This removes error messages when $fish_function_path is borked.
Turns out that `make -pn` actually takes a while - about 300ms on
fish's makefile.
That's quite a bit of time just to throw away the output and use the
exit code.
So we just check for "GNU" in the version string.
It would be nice to just _do_ the completion and fall back on the
BSD-style if it doesn't work, but that is tricky to do with the pipe
to `awk` - the awk expression actually does not fail if `make` does
not print output.
And I don't know enough about awk to change that.
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
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.
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.
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).
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.
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
Can be used to retrieve a list of parent paths, useful for searching
ancestors recursively via their absolute paths. Paths are returned from
deepest to shallowest, starting from the path passed in. Paths are not
validated for performance reasons. (Usually the input to
__fish_parent_directories would be (pwd) or (dir $file).)
