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.
Just a skeleton completion file, but the list of available
actions/completions is at least dynamically generated (there's a lot of
them, they are impossible to remember, and they depend on build
options).

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.
This allows us to send proper debug messages via FLOG, and it removes
more things from share/config.fish.
Note that the logic differs in some subtle ways. For instance it will
now obey $COLORTERM, so if that isn't "truecolor" or "24bit" it will
deactivate truecolor.
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
`go run` compiles and runs a go program passing along the trailing args to the compiled program. Limiting `go run` to only complete *.go files means that if you are running a go file that takes a file path as a command line argument, you frustratingly cannot use tab completion.
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.
pacman -U is intended to be used with (among others) files like this:
# pacman -U ./linux-headers-5.6.2.arch1-2-x86_64.pkg.tar.zst
Thus, let's enable file path completion for this kind of operation.
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.
a) they can screw up our expected output/behavior
b) they can blow up your system
In my case, the unit tests were calling Pantheon's fish integration
script which would then proceed to blow up dbus with messages about each
individual test completing.
The colors defined in `colorutils.js` are specified in
fish format, and therefore RGB values lack the leading
`#` character and do not fully follow the html/css spec
(w3.org/TR/css-color-4/#typedef-hex-color).
Web config sends these values as-is to the browser,
without first converting to a browser-friendly format.
While this (somehow) works for the most part, a few
colors get lost along the way and do not display in
the customization selector nor in the preview when
selected. This behavior was seen in Firefox.
To fix this, let's prepend the missing '#' character
to all RGB colors defined in `colorutils.js`.
This improves some generated completions, for example:
diff -u completions.old/g3topbm.fish completions.new/g3topbm.fish
+complete -c g3topbm -o stop_error -d 'This option tells g3topbm to fail when it finds a problem in the input'
-complete -c g3topbm -o stop_error
This used to use "success", which was our own thing, but which I can't
get working.
So instead we just use ".then", which only passes one object as an
argument that then contains all the other data we use.
This should be enough to complete the port to angular 1.8
* 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.
