It's now good enough to do so.
We don't allow grid-alignment:
```fish
complete -c foo -s b -l barnanana -a '(something)'
complete -c foo -s z -a '(something)'
```
becomes
```fish
complete -c foo -s b -l barnanana -a '(something)'
complete -c foo -s z -a '(something)'
```
It's just more trouble than it is worth.
The one part I'd change:
We align and/or'd parts of an if-condition with the in-block code:
```fish
if true
and false
dosomething
end
```
becomes
```fish
if true
and false
dosomething
end
```
but it's not used terribly much and if we ever fix it we can just
reindent.
We just do a cheesy version check and hope it works out.
If this is fixed in 10.15.4, we have to reenable it. If it still isn't
fixed in 10.16, we need to adjust it.

This is part of our (well, my) quest to spice up the default prompt.
In this case we color the host if $SSH_TTY is set, which is easy to

This variable holds an integer that resembles the fish version up to
that initializations were performed. It should be incremented whenever
some new initialization is required after upgrading fish. This should
not change the behavior for existing fish installations, except for a
minor message on installations that upgrade from fish<2.3.0.

This use of eval is unsafe, not really all that useful and can spew

This prefixes files beginning with `-` with a `./` when generating
completions *in fish code*. Standard completions for directory listings
generated by the C++ directory traversal code are not afected by this
patch.
Most fish completions defer to `__fish_complete_suffix` to generate the
file/directory completions, these *will* be corrected.
* Make `type -p` and `type -P` behave as documented
* Recognize `-` as an additional sign of no path
Functions created via `source` (like by `alias`) cause `functions --details` to return `-`
rather than `stdin` when invoked upon them.
* Add the `--succinct` flag to `type`
* Use `echo` rather than `printf`
* Change `succinct` to `short`; print path if known
* Clean up the printing logic ever so slightly
This was mostly dead, since $fish_color_host is set to normal in

explicitly unsets fish_color_host (which they shouldn't, really).
Anyway it's weird to use cyan, use normal instead.

(command pwd) uses the system's implementation of pwd. At least the GNU
coreutils implementation defaults to -P, which resulted in symlinks being
expanded when switching between directories with nextd/prevd.
This did some weird unescaping to try to extract the first word.
So we're now more likely to be *correct*, and the alias benchmark is
about 20% *faster*.

Presently the completion engine ignores builtins that are part of the
fish syntax. This can be a problem when completing a string that was
based on the output of `commandline -p`. This changes completions to
treat these builtins like any other command.
This also disables generic (filename) completion inside comments and
after strings that do not tokenize.
Additionally, comments are stripped off the output of `commandline -p`.

Every builtin or function shipped with fish supports flag -h or --help to
print a slightly condensed version of its manpage.
Some of those help messages are longer than a typical screen;
this commit pipes the help to a pager to make it easier to read.
As in other places in fish we assume that either $PAGER or "less" is a
valid pager and use that.
In three places (error messages for bg, break and continue) the help is
printed to stderr instead of stdout. To make sure the error message is
visible in the pager, we pass it to builtin_print_help, every call of which
needs to be updated.

BSD `seq` produces a down-counting sequence when the second argument is
smaller than the first, e.g.:
$ seq 2 1
2
1
$
While GNU `seq` produces no output at all:
$ seq 2 1
$
To accommodate for this behavior, only run `seq` when we are sure that
the second argument is greater than or equal to the first (in this case,
the second argument `line_count` should be greater than 1).

* Fix default Alt+W keybinding
The old keybinding would chop off the last line of the `whatis` output
when using a multi-line prompt. This fix corrects that.
* Make variable local and remove unneeded if statement
* Test that token is non-empty
Reproducer: type `: \<RET><M-p>`. This used to print an error due to builtin test receiving
too many arguments.
It looks like (commandline -j) can return multiple items, because a job can be broken up in multiple
lines terminated by backslashes.
With the new support for self-insert inserting a bound sequence,
the default binding for space as expanding abbreviations can be simplified
to just `self-insert expand-abbr`. This also fixes the bug where space
would cancel pager search.
By not manipulating each line or even each file at a time, we can go
back to `string` and piece together a pipeline that will execute
significantly faster than shelling out to `awk` will. This also removes
one of the few dependencies on `awk` in the codebase.
With this change, `__fish_print_hostnames` now finishes ~80% faster than
it used to a few commits back.
Reordering the `getent hosts` and read from `/etc/hosts` combined with
minimizing shelling and job invocations for parsing the output results
in a profiled and benchmarked ~42% decrease in the time it takes to run,
and that's on a machine with a very small hosts list in the first place.
This update also fixes the hadling of IPv6 addresses in the hosts
output, which were previously ignored, and ignores 127.* loopback
addresses in addition to the 0.0.0.0 address (plus adds support for
shorter IPv4 notations).
$__fish_git_prompt_use_informative_chars will use the informative
chars without requiring informative mode (which is really frickin'
slow!).

This previously effectively checked `string split ' '`s return status,
which was false if it didn't split anything. And while that should be
true if getent fails (because it should produce no output), it's also
true if it doesn't print a line with multiple aliases. Which should be
fairly typical.
Instead we use our new-found $pipestatus to check what getent returns,
in the assumption that it'll fail if it doesn't support hosts.
Follow up to 8f7a47547e.

`getent hosts` is expensive-ish - ~50ms, so we don't want to run it
twice just to figure out it works.
Apparently this works everywhere but CYGWIN and possibly older
OpenBSD, but we don't want to explicitly blacklist those.
[ci skip]
If you changed $__fish_git_prompt_show_informative_status, it

unset $___fish_git_prompt_init, so we just kept chugging along with

This way we use our core file completion code, which is much more

This was quite famously rather complicated.
We drop a bunch of cases - we can't handle tmux-starting-terminals
100% accurately, so we just don't try. It should be quite rare that
somebody starts a different terminal from tmux.
We drop the `tput` since it is useless (like terminfo in general for
feature-detection, because everyone claims to be xterm).
So we just check if we are in konsole, iTerm, vte or genuine-xterm.

Dealing with macOS output in a fast manner using `string` is surprisingly hard, given that it features lines like

* Honour `dirprev` scope
Honour the scope of the `dirprev` variable if it is universal
and avoid to shadow it with a global. This enables to share
the `cd` history between sessions.
* Honor dirnext and __fish_cd_direction scope
If these variables exist in the universal scope, do not shadow them
`eval` has always been implemented as a function, which was always a bit
of a hack that caused some issues such as triggering the creation of a
new scope. This turns `eval` into a decorator.
The scoping issues with eval prevented it from being usable to actually
implement other shell components in fish script, such as the problems
described in #4442, which should now no longer be the case.
Closes#4443.
If we switch the bind mode, we add a "force-repaint" there just to
redraw the mode indicator.
That's quite wasteful and annoying, considering that sometimes the prompt can take
half a second.
So we add a "repaint-mode" function that just reexecutes the
mode-prompt and uses the cached values for the others.

* Add "expand-abbr" bind function
This can be used to explictly allow expanding abbreviations.
* Make expanding abbr explicit

We no longer trigger an abbr implicitly, so we can remove the code
that does it.

This searched for package.json in any parent, so just like finding
.git and .hg directories it _needs_ to use the physical pwd because
that's what git/hg/yarn use.
In general, if you do _any_ logic on $PWD, it should be the physical
path. Logical $PWD is basically only good for display and cd-ing
around with symlinks.

This called `eval $fish_browser --version` to figure out if it is
lynx.
That's really not worth it just to support edge-cases using a rather
unusual browser, to work around a bug in it.
Instead we just see if the browser name starts with "lynx", which
should work in 99.9% of cases.
This created another local version of the variable just for the if-block.
Can't say I love the space prefix, but then I think we have too many
of these modes anyway.
If you use these to figure out if there _are_ staged files, or dirty
or whatever, you currently need to check the output, which relies on
the configured character.
Instead, we let them also return a useful status.
Notably, this is *not* simply the status of the git call.
__fish_git_prompt_X returns 0 if the repo is X.
This works for untracked, but the "diff" things return 1 if there is a
diff, so we invert the status for them.

Apparently if you install gnu coreutils on OpenBSD, the tools are
g-prefixed. So we definitely want to just alias that rather than
provide our lousy shell script implementation.
25d83ed0d7 (included in 3.0.0) added a `string` check that

Apparently nobody is using this.

That seems suspect.
It removes files starting with "# Autogenerated", but those files
usually do not show up in ~/.config - they're in ~/.local/share.

This did `argparse`, but only handled "--help". Any other options

NetBSD's man is unusual in that it doesn't understand an empty

`manpath` or `man --path`.
It has a `-m` option that would be useful, but other mans also have a
`-m` option that isn't, so detecting it is tough.
It does have a `-p` option that almost does what one would want here,

Prior to this fix, we would write to a fifo via cat >$filename & .
However in some cases (and soon in all cases) we open the file before
the fork, not after. This results in a deadlock because the file open
cannot succeed until a write begins.
Switch to using tee to write to the file. Because tee opens the file itself,
fish is no longer responsible and the deadlock is resolved.

We were checking for the $TMUX variable to determine if we were
running under tmux. However when running the tests, the terminal becomes
expect, even though the TMUX variable is still set, so we spew tmux-isms
at expect. Check the value of $TERM for 'screen'.
This allows disabling _just_ the informative status.
We still also use the dirty and untracked variables, but only if
informative status hasn't explicitly been enabled.
If either of the two git config variables:
- bash.showDirtyState
- bash.showUntrackedFiles
is explicitly set to false, we will disable informative status, and
fall back on the non-informative version (most likely still with
either dirty or untracked files, since we already use the variables
for that).
These vars are read by the official git prompt, so we use them instead
of inventing our own "fish.showInformativeStatus".
(Note: This also uses $__fish_git_prompt_showdirtystate and friends,
but only when there's nothing set in the repo, and there's really no
reason to set those to false if using the informative status)

Expands the utility of `type -p foo` by allowing it to print the path to
the script that defines `foo` when `foo` is a valid function that was
sourced from a path on disk (rather than interactively defined).
This does not change the behavior of `type -P`/`type --force-path`,
which should have already been used if the desire was to resolve the
path to an executable file (otherwise the output would have been blank
if a function was shadowing an executable file of the same namea), so no
backwards compatibility issues are expected.
Previously, using special regex characters or slashes would result in an
error message, when pressing tab in a command-line such as
"man /usr/bin/time ".
Make it so that the generated completion has the form \t\n
when the optional description has been ommitted - otherwise
the original option's description gets inherited and is seen hundreds
of times repeating in the pager.
GNU ls's --indicator-style=classify is the same as POSIX -F.
Refactor and change command testing logic so that we define the

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

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)

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

fish script.

* 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

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.

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.

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.

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.

This allows for marking certain bindings as part of a preset, which allows us to

- 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).)
* Add eopkg support
Add support for eopkg in __fish_print_packages function, and

* Use string function to replace grep and cut
* Add completion for search command
This was caused by it prepending "-s" to argv always,
and later checking $argv[1].
As it turns out, that is kinda superfluous, so we can just add "-s" to
the `bind` calls.
Also adjust the tests so the vi-bindings are enabled via the function,
which would have caught this.
Fixes#4494.
The previous hack used to work around an OS X issue/bug where launching
a URL with a #fragment appended would drop the fragment by using
`osascript` does not seem to work any more. Append the section name as a
query string (in addition to, not instead of #section) and then use some
basic javascript appended to the user doc HTML template to parse that
and jump to the correct section (if the section was dropped).
Closes#4480
E.g. if "foo" is in CDPATH, and both "foo/bar" and "./bar" exist, `cd
bar` will go to ./bar.
The completions described "bar" as going to "foo/bar" ("CDPATH foo").
This fixes it by checking for ./bar's existence.
See #4475.
This silences binding errors due to keys not found in the current
termcap config in the default fish bindings.
Closes#4188, #4431, and obviates the original fix for #1155
It was necessary to re-implement builtin_bind as a class in order to
avoid passing around the options array from function to function and
as adding an opts parameter to `get_terminfo_sequence` would require
otps to be passed to all other builtin_bind_ functions so they could, in
turn, pass it to `get_terminfo_sequence`.
This
- Offers more candidates
- Is more reactive (it'll always incorporate "--state=" and "--type="
- Is faster (about 800ms to about 120ms)
- Needs fewer function files
All __fish_systemctl_* functions except __fish_systemctl_services have

Decided to move doc_src/fish.lss to share/lynx.lss, which just makes
more sense all around. Accordingly, now using {$__fish_datadir} instead
of {$__fish_help_dir} in help.fish.
Makefile now installs the custom lss on make install
Lynx uses a very naïve method of applying styles to HTML elements by
hashing the element type and the class name to generate a map of
hash:style. After the hash is calculated, Lynx does not go back and
check whether or not the actual string values match the LSS properties.
See the following links on the Links mailing list:
* http://lists.gnu.org/archive/html/lynx-dev/2015-12/msg00037.html
* http://lists.gnu.org/archive/html/lynx-dev/2015-12/msg00039.html
This patch copies the default Lynx stylesheet but removes highlighting
and other styles that would result in unreadable text (due to not enough
contrast with the background color), and if the `help` builtin detects
that the best web browser to use is Lynx, it instructs it to use this
modified stylesheet.
If the $DISPLAY environment variable is not set, xdg-open should not be
used to load the web browser. Just because it is installed does not mean
that the user exclusively runs in an X session.
Needed for Lynx detection to work around #4170
Thanks to @ThomasAH, as per #4378. Tested on many platforms (OS X,

Drawing prompt in repo with text=auto attribute and mixed line endings in files was spawning crlf conversion warnings to terminal from unsilenced stderr of git diff
This flag was only documented for a few weeks before being renamed
`--show-time` and has been deprecated for a long time. Fish 3.0 is a good
opportunity to remove it.
* Implement `history search --reverse`
It should be possible to have `history search` output ordered oldest to
newest like nearly every other shell including bash, ksh, zsh, and csh.
We can't make this the default because too many people expect the
current behavior. This simply makes it possible for people to define
their own abbreviations or functions that provide behavior they are
likely used to if they are transitioning to fish from another shell.
This also fixes a bug in the `history` function with respect to how it
handles the `-n` / `--max` flag.
Fixes#4354
* Fix comment for format_history_record()
Using bare vars is more efficient because it makes the builtin `math`
expression cache more useful. That's because if you prefix each var with
a dollar-sign then the fish parser expands it before `math` is run.
Something like `math x + 1` can be cached since the expression is the
same each time it is run. But if you do `math $x + 1` and x==1 then you're
effectively executing `math 1 + 1`. And if x==2 the next time then you're
running `math 2 + 1`. Which makes the expression cache much less effective.
Remove our `math` function that wraps `bc`. Our math builtin is now good
enough that it can be the default implementation.
Another step in resolving #3157.
Rewrite the `abbr` function to store each abbreviation in a separate
variable. This greatly improves the efficiency. For the common case
it is 5x faster. For pathological cases it is upwards of 100x faster.
Most people should be able to unconditionally define abbreviations in
their config.fish without a noticable slow down.
Fixes#4048
The recent change to switch `psub` to use `argparse` caused it to use
a fifo by default because it inadvertently fixed a long standing bug in
the fish script. This changes the behavior back to `psub --file` being
the default behavior and introduces a `--fifo` flag. It also updates the
documentation to make it clearer when and why `--fifo` mode should not
be used.
Fixes#4222
While updating the `history` function to use `argparse` I realized it is
useful to define an option that can be used in three ways. First by
using the short flag; e.g., `-n NNN`. Second by using the long flag;
e.g., `--max NNN`. Third, as an implicit int flag; e.g., `-NNN`. This
use case is now supported by a spec of the form `n#max`.
A recent regression to the `alias` command points out the need for more
unit tests of its behavior. I also decided to use it as an opportunity
to normalize the output of just `alias` to list aliases.
The previous change to use `argparse` for parity with every other
builtin and function introduced a regression. Invocations that start
with a negative number can fail because the negative value looks like an
invalid flag.
This implements a `fish_opt` command that provides a way for people
to create option specs for the `argparse` command as an alternative to
creating such strings by hand.
Fixes#4190
Var `___git_ps_color_suffix_done` is supposed to be
`___fish_git_prompt_color_suffix_done`. This bug was found by an
experimental change to detect the use of undefined variables (#4163).
Similarly, we should simply test whether `__fish_git_prompt_showcolorhints`
is set rather than set to a non-empty string.
We now have a builtin that can do URL escaping so use it. I can't find
any uses of our private `__fish_urlencode` function in any Oh-My-Fish or
Fisherman code so remove it.
This is another step to resolving issue #1310. It makes
`fish_breakpoint_prompt` a replacement for `fish_prompt` if it is defined
and we're presenting a prompt in the context of a `breakpoint` command.

Per my comment in issue #3980 this implements `__fish_print_users` in
terms of `__fish_complete_users` so we don't have to modify both when a
change to how users are enumerated is needed.
This removes a need for packagers to either patch our shebangs or pick
a particular python.
This was already done in __fish_config_interactive (where we need to
duplicate the code because it involves backgrounding).
Work towards #3970.
Fixes invalid character in variable name $fish_cursor_replace-one (used by fish_vi_cursor[_handle]) by renaming bind mode 'replace-one' to 'replace_one'.

* More idiomatic error messages
* Store the checksum in a local variable
* MD5 function supporting both GNU and BSD
* Use `else if` in MD5 function

Reviewing a PR for a completion script caused me to look at the
implementation for the `__fish_complete_directories` function. Which in
turn lead me to create this change to improve its implementation and add
unit tests for the function.
This is to make pasting literals easier.
When a user pastes something, we normally take it as-is.
The exception is when a single-quote is open, e.g. the current token
is
foo'bar
When something is pasted here, we escape single-quotes (`'`) and
backslashes (`\\`), so typing a `'` after it will turn it into a
literal token.
Fixes#967.
This is a terminal feature where pastes will be "bracketed" in
\e\[200~ and \e\[201~.
It is more of a "security" measure (since particularly copying from a
browser can copy text different from what the user sees, which might
be malicious) than a performance optimization.
Work towards #967.
If the first word of the alias body ends with a semicolon we need to
strip that character, and otherwise escape the extracted command, to
ensure the subsequent function definition is valid.
Fixes#3860
ncurses since 6.0 sends the "E3" sequence along with "clear", even for
just `clear` or `tput clear`. This deletes the scrollback buffer which
is usually not what you want.
Fixes#2855.
Before this change the function `__fish_print_filesystems` would print
an error message about an empty wildcard match for the pattern
`$PATH/mount.*`, if the current operating system does not include any
helper binaries for the command `mount`. An example for such an OS is
the current version of macOS (version 10.12).
Change the escape key binding in insert mode (in vi key bindings)
to check if we are in paging mode. If so, emit cancel and stay in
insert mode. Otherwise perform the current behavior of switching
back to default mode and adjusting the cursor.
Fixes#2871
This commit addresses many of the style problems with the previous
commit. If this introduces any bugs they are solely my fault. The style
of this code needs more improvement. Some of which could be done today.
Others will have to wait until `fish_indent` is improved.
Add IPV6 /etc/hosts completion support. Parses columns rather than values which produces improved output.
Support ssh -F and Include completion
Ignore ssh Hostname and Host with wildcard. The following only get in the way:
- Hostname: Host resolves to Hostname
- Wildcard Host: Cannot ssh to a glob pattern
Improve scp completions
* complete only local files when no host provided
* complete only remote files when host is provided
* complete local files or hosts when no separator
Disable username completion for ssh/scp
Username completion only provides local users which will unlikely be
useful on a remote machine. ssh will use the current username (the only
useful one) or one provided in the ssh config.
* Added new function for the default prompt mode
Now fish mode prompt will call fish_default_mode_prompt, this will solve #3641
* Added function description
* Change wording for documentation about default mode prompt
* Finish changes requested in code review
This would fail on very long numbers, e.g.
`math "1 + 1233242342353453463458972349873489273984873289472914712894791824712941"`
would now return "42", where it previously returned the correct "1233242342353453463458972349873489273984873289472914712894791824712942".
This reverts commit 26e781ef5a.
It's not the case that macOS and old BC doesn't respect this environment
variable, just that they don't have special behavior when it's set to 0.
However, there is rather universal favorable behavior with a value of 2.
Output is of the form:
\
999999999999999999999999999999999...
with the second line being arbitrarily long. So just grab that line
instead of stitching with `string`.
This can yield a 25-30% speedup.
This commit adds a feature that after typing "git add" and pressing
"alt+h", the manpage for "git-add" instead of "git" would be displayed.
The new logic takes the first argument which doesn't start with a dash
and tries to display manpage for "command-argument"; it falls back to
"man command" it the first try doesn't succeed.
Fixes#3618.
- Support completing dynamic make targets.
- Support completing make targets when using -C/--directory.
- Support `-Cdir/path`, `-C dir/path`
- Support `--directory=dir/path`, `--directory dir/path`
This detects if the make command have the `-p` switch otherwise it
assumes it is BSD make and will run a different command to try to figure
out the available targets.
The recent refactoring to separate default (emacs) from vi key bindings
overlooked adding `\cH` bindings to vi mode. This also fixes the
behavior of the [del] key bindings (\x7F).
Fixes#3653
This implements a standard function and bindings for editing the command
line in an external editor. This feature has been requested multiple
times in the past year with various solutions cut and pasted into those
issues. This change combines the best aspects of those solutions.
Fixes#1215
I had disabled having `make style-all` restyling fish scripts because a
majority of them did not conform to the style enforced by `fish_indent`.
I recently restyled most of the fish scripts with the exception of the
completion scripts. So this re-enables restyling all scripts with the
exception of completion scripts.
The abbr function doesn't have the possiblity to rename abbreviations.
You have to delete the old one and create a new one. This commit adds
this functionality and uses the syntax:
abbr -r OLD_KEY NEW_KEY
Fixes#2155.
I hate doing this but I am tired of touching a fish script as part of
some change and having `make style` radically change it. Which makes
editing fish scripts more painful than it needs to be. It is time to do
a wholesale reformatting of these scripts to conform to the documented
style as implemented by the `fish_indent` program.
This augments the previous change for issue #3346 by adding an error
message when an invalid integer is seen. This change is likely to be
controversial so I'm not going to squash it into the previous change.
We cannot just use TERM = xterm and defined Ss sequence, as some old
vte-based terminals are still in the wild that don't support the
sequence and don't have $VTE_VERSION set.
I have tested this on

- new xterm - supported and works ($XTERM_VERSION)
- lxterminal-gtk3 - supported and works ($VTE_VERSION)
- new gnome-terminal - supported and works ($VTE_VERSION)
- lxterminal-gtk2 - not supported and deactivated (no $VTE_VERSION)
- tmux in konsole - works
- tmux in lxterminal-gtk2 - deactivated
and for all supported ones with the respective variable erased, to see
that it is deactivated.
Fixes#3499.
The changes related to issue #3068 removed most of the emacs bindings
from vi mode. However, since fish 2.4.0 was released several people have
pointed out that the directions for reinstating the legacy hybrid key
bindings don't work. This change fixes that and makes it easier to use
the legacy hybrid bindings.
Fixes#3556
While working on making the history command support case-sensitive and
insensitive searches I noticed that entering "all" when interactively
deleting history entries resulted in an error. That's because the
history builtin currently only supports `--exact` so we need to loop
over the matching entries and delete them one at a time.
Fixes#3448
My previous change to avoid creating a *.pyc file when running
create_manpage_completions.py was wrong because I put the
`sys.dont_write_bytecode = True` on the wrong line. Rather than simply
move that statement make the simpler, cleaner, fix that removes the need
for `eval` where that program is invoked.
After implementing `builtin fish_realpath` it was noticed that it did
not behave like GNU `realpath` without options. Which is super annoying
since that was the whole point of implementing the command. Major
failure on my part since I wrote the unit tests to match the behavior of
the existing `wrealpath()` function that I simply exposed as a builtin
command. Rather than actually verifying it behaved in a manner
compatible with GNU realpath.
Also, while the decision to call the builtin `fish_realpath` seemed to
make sense at the time of the original commit further reflection has
shown that to be a silly, idiosyncratic, thing to have done. So rename
it to simply `realpath`.
Fixes 3400
This adds a flag to the `history search` command to limit the number of
matching entries to the first "n". The default is unlimited. This is
mostly useful in conjunction with aliases (i.e., functions) that are
intended to report the "n" most recent matching history entries without
piping the result through the user's pager.
Fixes#3244
Don't wrap fish_indent at all if the version in $PATH matches
$FISH_VERSION.
When we do wrap it, resolve the path once, and use that via alias
machinery instead of doing an eval each time.
In both cases, `type fish_indent` can tell us what it's actually going
to do now.
clarity aside, it's faster if we only eval the one time.
eval is not only evil, but slow.

these modern terminals both compose a nicer title if we don't try to provide a custom one (no path in title twice, "fish" in title twice) - and the user can configure which components they'd like in their terminal inside the terminal preferences.
Also make test "$VTE_VERSION" -ge .. work once I commit `test` strtoi

This deprecates the use of long options for history sub-commands (e.g.,
`history --delete`) in favor of proper sub-commands (e.g., `history
delete`). It also eliminates the short options for those sub-commands.
Also change option processing to allow options anywhere on the command
line to match how the vast majority of fish builtins handle flags.

Fixes#3366.
Adds a color reset thing, to ensure fish tries to use hard colors during
testing.
Also, work on a discrepancy (not introduced by my changes, afaik) when
with some combinations of color settings, and usage of --bold, caused super
flakey color paninting in the pager. Downwards movements that trigger
scrolling vs. upwards movement in the pager would only apply bold to
selections when moving upwards. The bold state of the command completions in
the pager was flipping flops on and off, depending on if there is a description
on the preceding line.
Implement a lame fix by reseting the color to normal and applying a
different style on the rightmost ')' which seems to be what was influencing it.
Makes fish use terminfo for coloring the newline glich char.
The previous solution would not erase the previous bindings if
fish_vi_key_bindings was called with a mode argument. So if the user
switched to vi with a different initial mode, they'd keep their previous
bindings also.
Supersedes e89057b.
Some of these were defined in the shared bindings, some (like \cy yank)
were just literally duplicate in the same files.
This should _not_ change anything. In particular this does not remove
hardcoding of sequences (because terminfo might be wrong or the term
might need smkx).
Found with
```
function bind
set -l binds (builtin bind)
builtin bind $argv
set -l newbinds (builtin bind)
if set -q argv[1]; and not test "$argv[1]" = "--erase"
if test "$binds" = "$newbinds"
echo "Duplicate: " (string escape -- $argv)
end
end
end
```
The vi-bindings function would unconditionally erase all bindings,
making it impossible to call it last. This would disable the
mode-indicator (and in future also the cursor).
Make it so any argument to fish_vi_key_bindings stops it from erasing
bindings.
It would also be possible to demand an argument to erase (or to erase as
a separate step). but the usual case seems to be _switching_ to a set of bindings.
This didn't work on platforms where tput exists but can never accept
terminfo names. This includes the current versions of FreeBSD - it
used to do both, now it doesn't. So, fall back to the old termcap names
by (tput smso; or tput so). Add check for the tput program before we
even try.
The extra things `eval` does are all for code that runs
interactively. Because we just define a function, we don't need it.
This improves alias' performance by about 20-25% (0.783608s to 0.585585s
on about 500 aliases) and avoids triggering #3345.
Implementing the --shadow-builtin flag has proven to be highly controversial.
Revert the introduction of that flag to the `function` command. If someone
shoots themselves in the foot by redefining a builtin as a function that's
their problem and not our responsibility to protect them from doing so.
Fixes#3319
It's not ideal since we can't get the real result so we just assume it's
"0". That triggers the easier path, which still might display the wrong
thing, but we have to pick something.
Possible fix for #3321.
The recent change to reconcile the history builtin command and function
broke an undocumented behavior of `history --delete`. This change
reinstates that behavior. It also adds an explicit `--exact` search mode
for the `--search` and `--delete` subcommands.

Only on the OS X travis build.
I can't reproduce it but I figure it's something to do

Oops.
This was erroneously omitted from the previous commit.
Now backspace in insert mode does backward-delete-char, in default mode
backward-char (i.e. no deleting, just moving). This is consistent with vim.
This undoes the inheritance since it shared too much.
The idea here is to share bindings that aren't something the editors we're inspired by do - there's no "execute" in vi.
The basic editing and moving bindings are now vi-style in vi-mode and emacs-style in default mode.
Only one file belonging to fish-shell had DOS/bogus line endings,

hostname.fish.
Unsurprisingly, it has code to support cygwin and was likely
worked on by a user on a Windows machine. This will help
such cases in the future.
Also, in pcre2-10.21/, there was RunTest.bat which was (correctly)
CRLF formatted. We don't use this batch script at all, so rather
than LF it or add an exception, blast it away like the other pcre2
files omitted from the repo.
A common problem for users is that fish doesn't get a locale. This often
happens if systemd is used with getty and fish as login shell.
Fixes#277
Note that I (@krader) made editorial changes before merging this. For
example, running `make style` and otherwise changing long statements to a
series of shorter statements. So if there are any problems it is possible
I introduced them.
Fish assumed that it could use tparm to emit escapes to set colors
as long as the color was under 16 or max_colors from terminfo was 256::
if (idx < 16 || term256_support_is_native()) {
// Use tparm to emit color escape
writembs(tparm(todo, idx);
If a terminal has max_colors = 8, here is what happenened, except
inside fish:
> env TERM=xterm tput setaf 7 | xxd
00000000: 1b5b 3337 6d .[37m
> env TERM=xterm tput setaf 9 | xxd
00000000: 1b5b 3338 6d .[39m
The first escape is good, that second escape is not valid.
Bright colors should start at \e[90m:
> env TERM=xterm-16color tput setaf 9 | xxd
00000000: 1b5b 3931 6d .[91m
This is what caused "white" not to work in #3176 in Terminal.app, and
obviously isn't good for real low-color terminals either.
So we replace the term256_support_is_native(), which just checked if
max_colors is 256 or not, with a function that takes an argument and
checks terminfo for that to see if tparm can handle it. We only use this
test, because otherwise, tparm should be expected to output garbage:
/// Returns true if we think tparm can handle outputting a color index
static bool term_supports_color_natively(unsigned int c) { return max_colors >= c; }
...
if (term_supports_color_natively(idx) {
And if terminfo can't do it, the "forced" escapes no longer use the fancy
format when handling colors under 16, as this is not going to be compatible with
low color terminals. The code before used:
else {
char buff[16] = "";
snprintf(buff, sizeof buff, "\x1b[%d;5;%dm", is_fg ? 38 : 48, idx);
I added an intermediate format for colors 0-15:
else {
// We are attempting to bypass the term here. Generate the ANSI escape sequence ourself.
char buff[16] = "";
if (idx < 16) {
snprintf(buff, sizeof buff, "\x1b[%dm", ((idx > 7) ? 82 : 30) + idx + !is_fg * 10);
} else {
snprintf(buff, sizeof buff, "\x1b[%d;5;%dm", is_fg ? 38 : 48, idx);
}
Restores harmony to white, brwhite, brblack, black color names.
We don't want "white" to refer to color color #16, but to the
standard color #8. #16 is "brwhite".
Move comments from output.h to output.cpp
Nuke the config.fish set_color hack for linux VTs.
Sync up our various incomplete color lists and fix all color values.
Colors 0-8 are assumed to be brights - e.g. red was FF0000. Perplexing!

This is a regression introduced by 834ebef53c
Bolster with a check for only login sessions too -- hopefully makes it
less annooying on subshells in general.
Fixes#3261
This fixes several problems with how the builtin `history` command handles
arguments. It now complains and refuses to do anything if the user specifies
incompatible actions (e.g., `--search` and `--clear`). It also fixes a
regression introduced by previous changes with regard to invocations that
don't explicitly specify `--search` or a search term.
Enhances the history man page to clarify the behavior of various options.
This change is already far larger than I like so unit tests will be added
in a separate commit.
Fixes#3224.
Note: This fixes only a couple problems with the interactive `history
--delete` command in the `history` function. The main problem will be
dealt with via issue #31.
We don't seem to mention in the documentation that we were forcing
-t for all interactive uses. If we want to do that we should apply
that in the builtin.
history.fish reimplementing every option and doing things kind of
differently is a real pain and it's not clear if the docs are
referring to the or the wrapper script or both.
Someone running fish in an unusual locale reported that an `assert()` was
firing when they typed `pkill c`. I traced it to two bugs. First, the
__fish_make_completion_signals command was producing a weird result. Second,
the builtin `complete` command wasn't adequately verifying its arguments.
Fixes#3129
Doesn't colorize if output is redirected.
This is "fun" and indenting happens to make most of the included
functions display more narrow and fit better into a terminal window.

The previous commit to add a `--with-timestamp` flag to the `history` command
caused me to notice the history function didn't recognize the new long option.
Neither did it recognize the short options for the builtin command. This
change fixes both of those issues.
Improves experience during upgrades, accidentally running
an old fish with a new environment. No errors just from

1. It is possible to add multiple whitespace characters between the keyword (i.e. Host) and the argument(s).
2. It is allowed to have a single = and whitespace between the keyword and the argument(s).
3. It is possible to add multiple host names under a single Host directive by spacing the names apart.
1. and 3. are actual conventions that we use in our team, and I couldn't get auto-complete working for fish without this modification.
Modification explained:
a. The space between Host(?:name)? and the \w.* was replaced by (?:\s+|\s*=\s*) to match any sequence of whitespace characters, or optional whitespaces with a single =, per spec.
b. Result of first replacement is piped through another string replace to switch duplicate whitespace characters to a single space, and then piped to be split by that space. This allows specifying several aliases or host names in a single Host/Hostname definition, also per spec.

This was causing issues launching fish_config on OS X if fish.app is
renamed to contain a space (noted, but likely not the actual problem,
in issue #3140)
This makes fish_mode_prompt rely on $fish_key_bindings instead.
fish_bind_mode is also set in default mode (only always "default"), so
it can't be used as the indicator.
Closes#3067.

This speeds up the common case when IO is slow, e.g. when used with
sshfs.
We only use the short sha for figuring out whether the state is
valid (for which a long sha should also work) and for display when HEAD
is detached (I think that's the correct git-ism).
Working towards #3083.
This potentially leads to an unusable session (when fish_key_bindings is
set in config.fish to a value without corresponding function), so we
should take care.
* Add missing color definitions to __fish_init_1_50_0 reset.
The values where determined by inspecting the values of:
* fish_color_end
* fish_color_user
* fish_color_host
after resetting the color theme via fish_config.
* Add documentation for fish_color_user and fish_color_host.
(cherry picked from commit 08c29727e0)
It's currently too easy for someone to bork their shell by doing something
like `function test; return 0; end`. That's obviously a silly, contrived,
example but the point is that novice users who learn about functions are
prone to do something like that without realizing it will bork the shell. Even
expert users who know about the `test` builtin might forget that, say, `pwd`
is a builtin.
This change adds a `--shadow-builtin` flag that must be specified to
indicate you know what you're doing.
Fixes#3000
I'm going to modify these functions as part of dealing with issue #3000
and don't want those changes to be masked by running the files through
`make style`.
This makes it easy for the user to request floating point output with the
desired number of digits after the decimal point (not to be confused with
significant digits).
Note that this is just a thin wrapper so someone can say `math -s3 10 / 3`
rather than `math "scale=3; 10 /3"`.

There was an extended discussion in https://github.com/fish-shell/fish-shell/issues/2904 about using a bright yellow background to make the cancelled command indicator, ^C, standout. The upshot was that standout (i.e., reversing fg/bg colors) mode should be used until themes are agumented with proper support for background colors and special characters.

Not all distros have a `realpath` command. Provide a function that uses the

Also, correct the Vi mode default escape timeout. I intended it to be 100 ms
in my previous change but it ended up 10 ms which is far too short. A 10 ms
delay will continue to cause problems for people running fish inside `screen`,
`tmux`, or over high latency connections.

This ensures they can just be called and "the right thing" will happen -
fish_user_key_bindings will be executed, the variable will reflect the bindings.
This makes fish_mode_prompt rely on $fish_key_bindings instead.
fish_bind_mode is also set in default mode (only always "default"), so

I believe apm must have been buggy - example output that I found online
showed `tr` was mangling paths with spaces in it. Should be fixed.
Also, use dscl on OS X in __fish_complete_users.fish like
__fish_print_users.fish already does.
