__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
get rid of xargs
Created __fish_apropos and fixed __fish_complete_man to use that as well
moved macos apropos comment
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
to use the function instead. Add also the support of Administrator like
a root user.
Fixes: #7031
I really kinda hate how insistent clang-format is to have line
breaks *IFF THE LINE IS TOO LONG*.
Like... lemme just add a break if it looks better, will you?
But it is the style at this time, so we shall tie an onion to our
belt.
* Fix#7113 (cannot call help using msys2), correct a few regexes.
* Use regex instead of glob-style matching
* Match `\.exe$` instead of `cmd\.exe$` for WSL
* Match `\.exe(\s+|$)` instead of `\.exe$` and `cmd\.exe$`
* Fix 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.
* docs/faq: Mention prepend_sudo
[ci skip]
* __fish_prepend_sudo: Use $history[1] if commandline is empty
Currently, if you press alt+s with an empty commandline, it inserts
"sudo", which seems fairly useless.
Now, it inserts "sudo " followed by the last history entry, which
makes it a replacement for `sudo !!`.
* docs
This reverts commit 1b0ec21773.
"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.
