This was semi-automated with
```fish
for file in $argv
set -l varname (string replace -r '.*/(.*).html' '$1' -- $file | string escape --style=var)pages
set -l sections (string replace -rf '.*class="headerlink" href="#([^"]*)".*' '$1' <$file)
echo set -l $varname $sections
end
```
(where $argv contains the path to faq, fish_for_bash_users,
interactive, language and tutorial.html)
Building help.fish at compile time would work, but only for users who
build the docs.
As functions know where they are loaded from now, there is no point in
them being marked as loaded from a temporary file that has been removed.
Source the function via a redirect instead.
Ubuntu's fish package on WSL 1 has xsel as recommended dependency,
even though there is no X server available. This change makes us
use Windows' native clipboard even when xsel is installed.
We keep __fish_is_nth_token for compatibility and edit the
implementations of __fish_is_nth_token, __fish_is_first_token and
__fish_is_token_n to use fish_is_nth_token
This injected filenames into fish script, which could inject things
that looked like fish script.
E.g. create a file called `~/.config/fish/themes/"; rm -rf ~/*"`.
Note that the prompts are all shipped by us, but the themes can
technically be added by the user, and they might not be dilligent in
what filenames they allow.
`fish_config theme`:
- `list` to list all available themes (files in the two theme
directories - either the web_config/themes one or
~/.config/fish/themes!)
- `show` to show select (or all) themes right in the terminal - this
starts another fish that reads the theme file and prints the sample
text, manually colored
- `choose` to load a theme *now*, setting the variables globally
- `save` to load a theme and save the variables universally
- `dump` to write the current theme in .theme format (to stdout)
- `demo` to display the current theme
This introduces two functions to
- toggle a process prefix, used for adding "sudo"
- add a job suffix, used for adding "&| less"
Not sure if they are very useful; we'll see.
Closes#7905
I almost always use this on the last/only job in a commandline, so
the semicolon is usually not needed. We have always added it but I
prefer not dropping it: this feels cleaner because it's what you'd
type without the shortcut.
Similarly to b0e3cc4b5 (__fish_complete_suffix: Remove `eval`,
2019-12-28), this use of eval is unsafe and can spew errors if
invoked on an incomplete brace expansion.
Commit d15a51897 ("Rationalize $LESS uses") switched a "less" flag
from -r (interpret all control characters)
to -R (interpret only color codes)
Somehow this changed the output of "fish -c 'command -h'" to include
weird characters:
DESCRIPTION^O
command^O forces the shell to execute the program COMMANDNAME^O and ignore any functions or builtins with the same name.
Probably this was the reason why I originally used -r over -R. Anyway,
-R is safer and it looks like we can just remove the "ul" preprocessing
since "less" will interpret bold/underline just fine.
This has one slight behavioral change: Even with xsel, it now copies
to the clipboard, not the primary. I would imagine anyone who cares
about the primary selection has customized fish_clipboard_copy and
because we never got a bug about this not supporting anything but
xsel (and errorring out if it's not available!) this is probably
unused.
So now we support all the clipboard integration things, and we use the clipboard.
This change adds a binding that sets the s key's behaviour to match
the c key's in visual mode. This mirrors vim's behaviour (see `:h v_s`
in vim or neovim).
Apart from OpenBSD's "colorls" that is basically an ls that can do
color, there's also a ruby tool called "colorls" that's closer to exa.
Ignore that one since the options it understands are quite different
and I'm betting it's slower (given my experience with ruby tools).
See #8042.
* add support for colorized ls on openbsd
* add changelog line for colorls support
* add readme line for colorls support
* determine ls command at runtime, don't cache it
* eliminate __fish_ls_command function
Stop using "--no-init"/"-X" because we have no actual reason to and it
may break mouse initialization on my best friend macOS.
Use --RAW-CONTROL-CHARS, the capital version that only lets through
specific escape sequences, not *everything* - we shouldn't have
anything weird here, but less heavily discourages the other version.
Allow a user's $LESS to override.
Fixes#7997.
This isn't really a "locale" variable as such. It has no effect on
encoding and stuff, it's just the output language.
What we really want here is get something better than the awkward "C"
or "POSIX" for LC_CTYPE specifically - everything else doesn't really
matter.
From my checks (gnome-terminal with the "gnome light" colorscheme)
this seems to be the only color that's barely visible in a light
terminal, and it's the only color mentioned in both bug reports.
I'm leaving the artistic decisions to others, this is now *acceptable*
in both.
Note that, because we use universal variables here (hint #7317), this
will only be changed for preexisting installations when the user
reloads the colorscheme.
Fixes#3412Fixes#3893
It's a bit weird to *have* to fire up a browser to get fish_config to
choose a prompt.
So this adds a `prompt` subcommand to `fish_config`:
- `fish_config prompt list` shows all the available prompt names
- `fish_config prompt show` demos the available sample prompts
- `fish_config prompt choose` sources a prompt
- `fish_config prompt save` makes the choice permanent
A bare `fish_config` or `fish_config browse` opens the web UI.
Part of #3625.
TODO: This shows the right prompt on a new line. Showing it in-line is awkward
to do because we'd have to move it to the right.
Because MacOS' apropos is bad and doesn't support the `--` option
separator, this apparently spews errors.
Because the argument _can't_ start with a `-` (because we add a `^`),
we can just remove it.
Fixes#7965.
This prints a description of the "host". Currently that's
`(chroot:debianchroot) $USER@$hostname`
with the chroot part when needed.
This also switches the default and terlar prompts to use it, the other
prompts have slightly different coloring or logic here.
This called `uname` just to check if we *should* shorten "cygdrive"
directories.
That's more annoying than just doing it by default - on my system `pwd
| string replace` takes about 100 *micro*seconds, and this is done
once per prompt. Anyway, using $PWD further speeds it up to ~30
microseconds (compared to 10-20 for just `pwd`). This is hard to
measure because it's heavily impacted by system hitter.
The alternative is to ask cygwin to ship this feature as a patch.
Fixes#7926.
Also switches the default status order for non-informative to the informative one:
stagedstate invalidstate dirtystate untrackedfiles stashstate
instead of
dirty staged stash untracked
Because macOS' `apropos` is just using grep, and we only need
a prefix match for __fish_describe_command, we can shave off
some ok total execution time here.
No longer uses the __fish_apropos hack on every version of macOS.
Juat Catalina+.
The whatis database generated and replaced daily is 2 megabytes on
my computer, and in ~/.cache on a home dir might wind up on a net
mount or something annoying. or, definitely it's backed up by default.
It's wiser to throw that junk in with other cache files on the system
aka DARWIN_USER_CACHE_DIR, and only use the XDG directory if
someone specifically configured that.
Mainly, this just means at least it won't automatically get backed
up by Time Machine and stuff every day, which is no big deal but
y'know...
Rearranged stuff a little to not shell out every time.
The default vi mode prompt is kind of ugly, mostly because we include
this `[I]` with a super bright green background and white text,
which is particularly grating because most prompts don't actually have
a background.
So we get a ton of people asking "How do I remove this [I]" when they
could really benefit from having the mode shown.
There's a few ways to make this look nicer, the simplest is to just
keep the same colors but use them as foreground instead of background
colors, which looks much more understated.
The mode prompt is important, but not more than the actual contents of
the commandline, so it shouldn't have ALARMING colors.
This allows us to stop descending into untracked directories, which
can be faster.
It's still not *good* - git can still be quite slow here, but if
there's an untracked directory you probably don't care about the
number of files in that.
Fixes#7871.
Given that we no longer have that massive "index" page with
everything, it's become harder to open the correct section
immediately.
So this hardcodes the section titles for each page in help itself.
This was half-automated with
grep -o 'a class="headerlink" href="#[^"]*"' /usr/share/doc/fish/faq.html | sort -u | string replace -r '.*#' '' | string trim -c '"'
The completions still need to be adjusted.
In vim p means paste *after* current character, so go forward a char before pasting.
Also in vim, P means paste *at* current position (like at '|' with cursor = line),
so there's no need to go back a char, just paste it without moving.
Prior to this commit "builtin -h" would silently fail when no
documentation is installed. This happens when running fish without
installing it, or when the docs are not installed.
See #7824
Previously, this message told the user to "set $BROWSER and try again". However,
when I first saw this error, I didn't know how I can set `BROWSER` in fish. Moreover,
I often see this error in situations when no browser will work. For instance, I might be
using fish over ssh, and I might either not know whether that system has a text-mode
browser installed or not want to use it.
A further improvement would be to report this message if a browser fails to start.
This actually *worked* in my tests which confuses me.
It really shouldn't, `apropos -foo` will complain about "-o" not being
a valid option.
It should be `apropos -- -foo`.
Now, of course there are awful apropos implementations, so let's see
if someone complains
When `fish` is running in the Chrome OS Linux VM (Crostini),
both `help` and `fish_config` opened a "file not found"
page. That is because on Crostini, `BROWSER` is usually set to
`garcon-url-handler`, which opens URLs in the host OS Chrome
browser. That browser lacks access to the Linux file system.
This commit fixes these commands. `help` now opens the URL on
www.fishshell.com. `fish_config` now opens the URL for the
server it starts. Previously, it opened a local file that
redirects to the same URL.
In the case of `help`, the situation could be improved further
by starting a web server to serve help. I don't know of another
way to access `/share/fish` from outside the VM without user
intervention, and I think that might be a part of the security
model for the Crostini VM.
It's hard to write a test for this. I checked that `help math`,
`python2 webconfig.py`, and `python3 webconfig.py` work on my
machine running in Crostini.
This was a handler for various prompt variables that called a repaint.
Unfortunately, if you set one of those *inside* the prompt (a logical
place for it), this would lead to something like #7775.
So, because this isn't actually *useful* as far as I can see (how do
you set these variables in a way that you're not already inside a
prompt or about to draw a prompt? in a key binding?), we remove it,
like we removed the repaint from git's variable handlers.
This `set -e` had a cartesian product that caused it to remove the
indexes separately, so the later indexes were off - removing the first
and then the second ends up removing the first and then the
old-*third* which is now the second.
Just quote the expansion so it runs in one go.
Fixes#7776
Because we removed repaint coalescing, currently setting any of the
git prompt variables in fish_prompt leads to a repaint loop (that
presumably aborts once it reaches the recursion limit).
Since repainting on these variables isn't really useful (when you
`set` them interactively you already get a new prompt), just remove
it.
There's two cases this "breaks":
- When you set a variable *after* the call to fish_git_prompt
- When you set a variable via a binding
In both of these it's not too much to expect an explicit "commandline
-f repaint", especially since for bindings that's already needed in
most cases, and setting a variable after using it isn't normal.
Fixes#7775.
Called as
__fish_print_pipestatus "[foo" "oof]" "|" (set_color green) (set_color --bold blue) 0 1 2
it would make the closing `oof]` bold green.
Fixes#7771.
In this context, as it stands, $last_pid will give fish's pid (because
of pgroup shenanigans).
Since that doesn't really work, just `disown` without and let fish
figure out what the last process was.
Theoretically this has an issue if someone started a background
process *before* the python script *and* that exits before we run
disown.
That's a vanishingly small window and this is only run on first start,
so it seems acceptable.
Fixes#7739.
When pasting a multiline command with indented blocks, extra indentation
from spaces, or tabs, is generally undesirable, because fish already indents
pipes and blocks. Discard the indentation unless the cursor or the pasted
part is inside quotes.
Users who copied fish_clipboard_paste need to update it because
__fish_commandline_is_singlequoted had an API change and was renamed.
__fish_print_commands just prints the commands we have man pages for,
and help uses that to figure out whether it should link
a command or a section. If the docs aren't installed it won't find
anything.
At least check the builtins, because we document them and it's easy.
This probably needs to be added at build time - glob
doc_src/cmds/*.rst.
This was only a thing in cygwin, and only a workaround because
cygwin's hostname was broken in 2013 and our sample prompts called it,
which caused errors in fish_config.
Our sample prompts no longer call `hostname` at all (they use
`prompt_hostname`, which uses the variable), and it's possible
cygwin's hostname was fixed in the meantime.
Fixes#7669.
Over in https://github.com/wez/wezterm/issues/115#issuecomment-765869705 one of my users noted that fish had automatic OSC 7, but that it wasn't enabled under WezTerm.
You can detect WezTerm through the `$TERM_PROGRAM` environment. In practical terms, all versions of wezterm in the wild support OSC 7 so a version check is not needed.
I'm not a fish user myself, but I did give the equivalent change to this a try on my Fedora 33 machine (it has an older version of fish).
I can see in this file that there's some stuff with `__fish_enable_focus` that you may also want to enable under wezterm; the escape sequence is supported as are panes, tabs and windows.
As mentioned in 5b706faa73, bare
`disown` has a problem: It disowns the last *existing* job.
Unfortunately, it's easy to see cases where that won't happen:
sleep 5m &
/bin/true & # will exit immediately
disown # will most likely disown *sleep*, not true
So what we do is to pass $last_pid.
In help especially this is likely to occur because many graphical
browsers fork immediately to avoid blocking the terminal (we only
added the backgrounding and disown because some weren't).
Note that it's *possible* this doesn't occur if used in the same
function, but I don't want to rely on those semantics.
It might be worth doing this as the default - see #7210.
This allows for multiple edits to be undone/redone in one go, as if they
were one edit.
Useful when a function is editing the commandline buffer via scripted
changes or via a keybinding so the internal changes to the buffer can be
abstracted away.
(Having extreme difficulty getting pexpect to play nice with the concept
of undo/redo...)
It also reflows.
We might want to think about doing something more extensible here, as
konsole is also about to add reflow, but for now the main problem
children here are VTE and alacritty.
Extends #7491.
Of note: The rpm/yum thing seems to be coupled, so I put it into one
function that tries the yum helper and uses the rpm path otherwise.
Zypper is already its own thing, so this should only be used for yum
and probably dnf (does that still have the helper?)
Zypper can be dropped, as that already used a separate function in the file.
Apk can just be inlined - it's literally one line for installed and another for all packages.
This function doesn't make any sense.
Most things that expect package names expect package names for *one
specific package manager*.
It only happens to work, most of the time, because most people only
have one package manager installed.
The code to override the `(status current-command) was present`, but not
handled in either the default `fish_title` function or the fallback.
Closes#7444.
Use the `-d` parameter to `zfs list` to limit snapshots to the dataset
named in the current token being completed. Thanks to @Debilski for the
tip.
Closes#7472
Only generate the list of snapshots when
a) the argument must be a snapshot and nothing else, or
b) the argument as typed contains a literal @, or
c) a snapshot is a valid completion and there is only one dataset
matching the argument as entered.
Unfortunately, it seems the `zfs` command itself is extremely primitive
and doesn't support listing snapshots by dataset so when we need to
generate completions, we end up needing to enumerate all snapshots
(ever) across all datasets. I'd be very happy to be proven wrong, but I
think the only other way would be manually parse `zdb` output.
See #7472
- clip.exe is used to copy to the Windows clipboard
- There's no binary for pasting from the Windows clipboard so
`Get-Clipboard` from powershell is used as a workaround. The
superflous carriage return is stripped from the output.
This is super cheesy.
One of the most common feature requests we get is "control-r must
search", even tho just using history-search-backward via e.g. up-arrow
is perfectly capable. The only real difference is that ctrl-r search
in other shells allows editing the search term by default, while we
stop the history search and edit the new commandline in those cases.
So, since the major problem is muscle-memory on ctrl-r,
let's just use that!
This makes ctrl-r do nothing on empty commandlines, and do
history-search-backward otherwise, so the basic flow of "press ctrl-r
to start history search, enter your search term, press ctrl-r to cycle
through matches" just works (except the first ctrl-r is useless and it
doesn't show anything).
See #602.
These aliases seem to be common, see #7389 and others. This prevents
recursion on that example, so `alias ssh "env TERM=screen ssh"` will just
have the same completions as ssh.
Checking the last token is a heuristic which hopefully works for most
cases. Users are encouraged to use functions instead of aliases.
In the new __fish_apropos, makewhatis is run explicitly to generate the
whatis database. However this can be a little slow. Run it in the
background, after the apropos call completes so as to avoid a weird
race.
This means that descriptions may not be available the first time the
user invokes it, but that's better than appearing to hang for a while.
override MANPATH used by apropos with local whatis database and update it once a day

Created __fish_apropos and fixed __fish_complete_man to use that as well

This was a wrapper around status_to_signal, just because that only
handled a single argument.
Instead, just teach status_to_signal to handle multiple arguments and
be done.
This is too important to not be one.
For one if it couldn't be loaded for any reason it would
break a lot of fish scripts.
Also this is faster by ~20x.
Fixes#7342
"function --argument" is not a thing, it's "--argument-names". This only
accidentally works because our getopt is awful and allows abbreviated
long options.
Similarly, one argparse test used "--d" instead of "-d" or "--def".
When pressing \ep on an empty commandline, the cursor would stay at the
beginning of the commandline. Move it to the end of the previous command,
this feels a bit more natural.
The case for symlinked directories being duplicated a lot isn't there,
but there *is* a usecase for adding the symlink rather than the
target, and that's homebrew.
E.g. homebrew installs ruby into /usr/local/Cellar/ruby/2.7.1_2/bin,
and links to it from /usr/local/opt/ruby/bin. If we add the target, we
would miss updates.
Having path entries that point to the same location isn't a big
problem - it's a path lookup, so it takes a teensy bit longer. The
canonicalization is mainly so paths don't end up duplicated via weird
spelling and so relative paths can be used.
Since version 5 (IIRC), pacman has a file database.
This is useful for people who don't have pkgfile, but we still prefer
that because it's much faster - pacman takes a full *second* on my system.
This could lead to an infinite loop (well, stack overflow) because
fish_command_not_found would also be defined to call
__fish_command_not_found_handler.
Since this is for
- missing command errors
- when downgrading
we can just remove it.
Previously, when a command wasn't found, fish would emit the
"fish_command_not_found" *event*.
This was annoying as it was hard to override (the code ended up
checking for a function called `__fish_command_not_found_handler`
anyway!), the setup was ugly,
and it's useless - there is no use case for multiple command-not-found handlers.
Instead, let's just call a function `fish_command_not_found` if it
exists, or print the default message otherwise.
The event is completely removed, but because a missing event is not an error
(MEISNAE in C++-speak) this isn't an issue.
Note that, for backwards-compatibility, we still keep the default
handler function around even tho the new one is hard-coded in C++.
Also, if we detect a previous handler, the new handler just calls it.
This way, the backwards-compatible way to install a custom handler is:
```fish
function __fish_command_not_found_handler --on-event fish_command_not_found
# do a little dance, make a little love, get down tonight
end
```
and the new hotness is
```fish
function fish_command_not_found
# do the thing
end
```
Fixes#7293.
Commit 5d135d555 (prompts: fix pipestatus for jobs prefixed with "not")
introduced a backwards compatibility hack about adding an optional argument
to __fish_print_pipestatus. This hack would break downgrading to fish 3.1.2
if the user copied the new prompt to their config - they would get a backtrace
on every prompt which is arguably worse than the patch's minor improvement.
This does away with the error trace - old fish just won't show the fancy
new pipestatus on `not true`.
Implemented by passing the last $status as the poor man's kwarg, which works
since 3.1.0 (9b86d5dd1 Export all local exported variables in a new scope).
The prompts don't work with fish 3.0.0 or older; downgrading does not seem
too important in general but I think this patch is an okay simplification.
Now command, jobs, type, abbr, builtin, functions and set take `-q` to
query for existence, but the long option is inconsistent.
The first three use `--quiet`, the latter use `--query`. Add `--query`
to the first three, but keep `--quiet` around.
Fixes#7276.
These passed " [" to __fish_print_pipestatus as the left brace.
If the color contained a background, that would also color the space
in, leading to a weird unbalanced space before and none after.
Instead, prepend the whitespace when printing later.

* fix Subversion prompt
- after switching to "string match", some SVN status symbols need
proper escaping
- the __fish_svn_prompt_flag_names list was missing
"versioned_obstructed" and was therefore not in line with
the symbols from __fish_svn_prompt_chars
- when checking for individual SVN status symbols, use
"string match -e" to handle the case where multiple different
symbols appear in one status column
- use "sort -u" before merging all symbols from a column into
one line
Fixes#6715
* use regex for SVN status matching
Using regex matching will prevent different match behaviour
depending on qmark-noglob feature.
Also, counting the resulting matches is unnecessary.
* use list instead of string for SVN status
Make $column_status a list be not removing newlines from SVN status
output. This makes checking for the individual status types within
a column easier because it doesn't require regex matching.
* added quotes for string length test (-n)
This adds a "fish_greeting" function that prints the variable of the
same name.
In doing so, it makes $fish_greeting default to a global
variable (this is of little cost because of the `_` builtin)
This means that:
- We have fewer universal variables by default
- If we change the default greeting people will actually get
- it (unless they have a leftover universal, of course)
- If the user changes their language the variable changes with it
New fish_indent does that too, so this will make any future reformatting
diffs smaller.
Done using either of:
perl -pi -e 'undef $/; s/\n*$/\n/' share/**.fish
kak -n -f '<a-/>\n*<ret>d' share/**.fish
fish's internal completion logic is much smarter than the globbing in this
function, so let's just reuse "complete -C", and filter directories and
files with the given suffix.
Thanks to @Kratacoa for reporting on Gitter.
Using "complete -C" works well no prefix is given. Since in this repository
only the openocd completions pass a prefix, I left the prefix-case as is.
It could probably be improved and simplified as well. The prefix argument was
introduced to avoid cd's side effects inside a completion. Using cd is tempting
though because it would allow to use the same logic as without a prefix.
"repaint" here is a bit of a misnomer. It *doesn't* re-highlight, that
just happens on its own.
It re-runs the prompt, which can take quite a while (depending on the
configuration), and which is also useless in this context as this
isn't something the prompt will be reacting to (theoretically it
could, but I doubt the utility of displaying "PASTE" for a few milliseconds).
The external-commands-only completion was briefly added in 3.1.0 and removed
in 3.1.1 (see #6798), which means we can remove some dead code.
Maybe we should just remove __fish_complete_external_command - it could break
users, but then again, we don't really have a way to stop people from starting
to use this deprecated function. The underscores ought to communicate that
this is function is private to fish but that is not enforced.
If it can't recognize the DE, xdg-open uses a "generic" way of opening
things where it doesn't spawn off a DE-provided utility like kde-open.
This sounds great, but it fails to fork and therefore blocks the
terminal.
So we start it in the background and disown it.
Fixes#7215.
* Update apk-tools completions
Add completions of options of it's subcommands.
The completions of deprecated options is unimplemented.
* Fix installed package listing for apk-tools
An error occurs when the local cache does not exist, so fixed this.
This was always awkward as fish script, and had problems with
interrupting the autoloading.
Note that we still leave the old function intact to facilitate easier
upgrading for now.
Fixes#7145.
Add a helper function to check if the user is root. This function can be
useful for the prompts for example. Modify the prompts made root checked

I really kinda hate how insistent clang-format is to have line

* Fix#7113 (cannot call help using msys2), correct a few regexes.

This allows cygstart to be manually set as a browser, with or without arguments
This had this weird "pass along the sha, then check" logic to it which
is entirely unnecessary.
This function just says when something is staged, nothing more. Why
that is you can figure out for yourself.
This makes it easier to call this function, and it no longer prints an
empty line if nothing is staged.
This wasn't added to the prompt status order, so it was computed and
then not used for the informative prompt.
We still check later if we should compute it, so this is harmless if
showstashstate is unset.
Fixes#7136.
On my system this printed just "Description:" without any additional
characters, so this awkward `sed` didn't match and produced *all
packages on one line*.
Tbh this should probably be rewritten, but first we'd have to find a
way to get proper output here.

makes it a replacement for `sudo !!`.

"Interactive" has multiple meanings here, one of them being "the whole shell" is interactive, which `status is-interactive` tests, and one "this interaction is interactive", which happens when `read`ing in a script.
Fixes#7080.
* Add an "_" builtin to call into gettext
We already have gettext in C++ (if available), so it seems weird to
fork off a command to start it from script.
This is only for fish's own translations. There's no way to call into
other catalogs, it just translates all arguments separately.
This is faster by a factor of ~1000, which allows us to call
translations much more, especially from scripts.
E.g. making fish_greeting global by default would hurt cost-wise,
given that my fish starts up in 8ms and just calling the current `_`
function takes 2ms, and that would have two calls.
Incidentally, this also makes us rely on a weirdly defined function
less, so it:
Fixes#6804.
* docs: Add `_` docs
Let's see if that filename works out.
* Reword _ docs
This is a function you can either execute once, interactively, or
stick in config.fish, and it will do the right thing.
Some options are included to choose some slightly different behavior,
like setting $PATH directly instead of $fish_user_paths, or moving
already existing components to the front/back instead of ignoring
them, or appending new components instead of prepending them.
The defaults were chosen because they are the most safe, and
especially because they allow it to be idempotent - running it again
and again and again won't change anything, it won't even run the
actual `set` because it skips that if all components are already in.
Fixes#6960.
fish_git_prompt encloses its output in brackets, however this can be changed by supplying a format string to it, i.e. `fish_git_prompt %s`.
However when using `fish_vcs_prompt` there's no way to pass on the arg to fish_git_prompt, so you need to manually remove it.
fish_hg_prompt doesn't have the same format string support as fish_git_prompt, but I suppose it could be added later if needed.
We don't need to call it if a job was stopped, because in that case
read_i() will fire fish_prompt already, because the newly stopped job
was probably a foreground job.
Fixes#1018
The default implementation will not print any output in that case, but this provides users with additional flexibility when it comes to customising the shell's behaviour.
This allows users to customise the behaviour of the shell by redefining the function. This is similar to how fish_title or fish_greeting behave, where the default implementation can be easily overridden.
The function receives as arguments the job id, command line, signal name and signal description.
At the moment calling __fish_prepend_sudo multiple times does not toggle
sudo, and also unnecessarily uses the `-c` flag to `commandline` to see if
the first token on the commandline is "sudo".
This change removes the `-c` switch and also toggles "sudo" on multiple
calls to __fish_prepend_sudo, while maintaining the cursor position and
while maintaining any spaces between "sudo" and the next token on the
commandline.
The completions for help know many more help topics, it makes no sense
to whitelist them here.
Fix anchor links for tutorial sections.
Remove some dead code: the "man" branch was unreachable because of the
earlier (__fish_print_commands) case.
It removed $KONSOLE_PROFILE_NAME and added $KONSOLE_VERSION.
Let's assume if $KONSOLE_PROFILE_NAME is set we use the old sequences,
if not we use the new ones.
This reverts commit 535845861a.
That commit introduced a bug where tab-completing commands no longer
prints their descriptions, unless there is an exact match.
When this switched over from directly piping commandline to storing
its output and using printf, I inadvertently always added a trailing
newline. That's probably annoying.
Note that this will now always *remove* a trailing newline (because
the command substitution does). That will barely make a
difference (because trailing newlines are quite unusual in the
commandline) and will probably feel better than keeping it - we could
even make a point of removing trailing whitespace in general.
Fixes#6927
This updates the behavior of tilde to match the behavior found in vim.
In vim, tilde toggles the case of the character under the cursor and
advances one character. In visual mode, the case of each selected
character is toggled, the cursor position moves to the beginning of
the selection, and the mode is changed to normal. In fish, tilde
capitalizes the current letter and advances one word. There is no
current tilde command for visual mode in fish.
This patch adds the readline commands `togglecase-letter` and
`togglecase-selection` to match the behavior of vim more closely. The
only difference is that in visual mode, the cursor is not modified.
Modifying the cursor in visual mode would require either moving it in
`togglecase-selection`, which seems outside its scope or adding
something like a `move-to-selection-start` readline command.
The description for an alias which already has escape sequences will
use backslash escapes for quoting; usually `string escape` can simply
quote it. Use a regex that accepts either escaping style.
Fixes#6798
This re-adds some false positives: functions, builtins and abbreviations
are suggested after commands like sudo but I don't think anyone had
complained about that.
Many people have mentioned wanting support for changing / yanking /
deleting between "" and '', meaning the commands `ci' ci" yi' yi" di' di"`,
so this adds that support in a generic, and thus potentially confusing way.
The concept is that we check for the character backwards and forwards
before making the selection. Unfortunately, this will also work for *any*
character that isn't `w` or `W`, so `cia` could change everything between
two `a` characters.
Looking through the [bind documentation](https://fishshell.com/docs/current/cmds/bind.html)
and input handler at `src/input.cpp`,
this is the best possible solution I could come up with until
`forward-jump` and `backward-jump` can accept input in the call to `bind`,
and not just from stdin, meaning we can write a binding as:
```
bind di\" backward-jump-till \" and repeat-jump-reverse ...`
```
If that were done, then other commands such as `di)` to go between `()` would
be possible.
There are also some added `y` bindings not part of #6648.
Let me know if you need anything else.
This reverts commit 7f402cdae7.
There are fundamental issues with `funced` and `funcsave` that prevent
this from working. A file and a function are not interchangeable.
Add completions for `downgrade` tool
Add new `--installed` option for printing Arch packages
Change Arch Linux package related completions to use `--installed`
add newline
The output of
systemctl list-units
seems to include a marker of '●' or '*' for some units, even if the
output is not going to a terminal and "--no-legend" and "--no-pager"
are given. This appears
to be a recent development, and there does not appear to be a flag to
disable it.
So we simply filter it out in the completions to once again hopefully
offer the actual units.
Fixes#6740
