It appears we can't find a system that ships rustc >= 1.67 and < 1.70,
so keeping it at 1.67 gains nothing.
1.70 is used in Debian 13, so that will be able to build fish out of
the box (12 was on 1.63 which was already too low).
After abandoning a commandline (for example with ctrl-c) it's nice to be
able to restore it. There is little reason to discard the requisite undo
information, so keep it.
git_version_gen fails on Noble Numbat because modern Git refuses
to read repo-local config if owned by another user.

vared.fish is installed at
/home/fishuser/fish-build/test/buildroot/usr/local/share/fish/functions/vared.fish
as oppposed to being sourced from share/functions/.
I'm not 100% sure why this happens but it doesn't seem wrong.
iTerm2 supports CSI u so the custom bindings are no longer needed. Sequences
like \e\eOC are Escape followed by an SS3 arrow key which we can already
decode separately.
In ImageMagick 7 or later, legacy commands have been replaced with
magick. Here a new functions, defines these completions and it is
called for `magick` and `magick convert`.

We were inconsistent about this for no apparent reason.
Also cleaning up in ~/.config/fish/completions is
irrelevant by now since we moved to ~/.local/share/fish 8 years ago.
Now that the parent commit moved it again, cleaning up that one seems
reasonable.
These take over two minutes under ASAN (like ~40 seconds without, so
they aren't quick to begin with), and don't really give any additional
insight.
So we skip them to save time
This allows making something like
```fish
abbr --add gc --position anywhere --command git back 'reset --hard
HEAD^'
```
to expand "gc" to "reset --hard HEAD^", but only if the command is
git (including "command git gc" or "and git gc").
Fixes#9411
I have no idea why this matches the string thrice when it is entered
once and suggestions are disabled.
I've seen this fail even on my local system, I expect it works because
of some terminal integration.
Running
echo foo | vim -
gets us in a weird situation because we put the job in fish's process groups.
It causes us to not set a PGID for this job, so it can't be resumed among
other things.
Stopping the job with ctrl-z and try to exit the shell causes a crash in the
"There are still jobs active" warning because the PID for the job is still 0.
Let's remove the assertion to restore previous behavior, and hopefully fix
this later.
Remove the last non scoped place where we disable protocols (just before
exec(1)); it's not necessary with the current approach because we always
disable inside eval.
There is an edge case where we don't:
fish -ic "exec bash"
leaving bash with CSI u enabled. Disable that also in -ic mode where we
don't have a reader.
In future we should use the same approach for restore_term_mode() but I'm
not sure which one is better.
We enable terminal protocols once at startup, and disable them before exit.
Additionally, we disable them while evaluating commands (see 8164855b7 (Disable
terminal protocols throughout evaluation, 2024-04-02))..
Thirdly, we re-enable protocols inside builtin read (where it's disabled
because we are evaluating something). All of these three are scoped and
statically guaranteed to not leak into each others scopes.
There is another place where we enable protocols non-scoped: when we
receive a notification that a job is stopped. If this is ever hit, things
will be imbalanced and we'll fail to restore the right terminal state,
or (more likely) crash due the assertion in terminal_protocols_enable().
This code path used to be necessary when we disabled protocols only while
actually executing an external command but we changed that in 8164855b7,
so it should no longer be. Remove it.
I haven't been able to find a test case, I'll try to do that later.
The main reason we changed the scope of protocols was focus reporting (#10408).
We have given up on that for now (outside tmux where I can't get it to work)
so we might want to reconsider and go back to the "optimized" approach of
enabling it for as long as possible. But this is simpler, easier to verify.
Try to keep the "backwards-incompatible" section reasonably short so
people can get a quick overview of what they need to handle.
So we split the "bind" part into two.
This tries to open the given file to use as stdin, and if it fails,
for any reason, it uses /dev/null instead.
This is useful in cases where we would otherwise do either of these:
```fish
test -r /path/to/file
and string match foo < /path/to/file
cat /path/to/file 2>/dev/null | string match foo
```
This both makes it nicer and shorter, *and* helps with TOCTTOU - what if the file is removed/changed after the check?
The reason for reading /dev/null instead of a closed fd is that a closed fd will often cause an error.
In case opening /dev/null fails, it still skips the command.
That's really a last resort for when the operating system
has turned out to be a platypus and not a unix.
Fixes#4865
(cherry picked from commit df8b9b7095)
wl-copy is a daemon process that serves its stdin to any wl-paste processes.
On Wayland, we launch it from fish_clipboard_copy. It then lives in the
same process group as fish (see `ps -o pid,pgid,comm`).
For some reason pressing ctrl-c inside the VSCode integrated terminal with
fish as the default shell kills the wl-copy process, thus clearing the
clipboard. On other terminals it works fine.
This is also reproducible by running "echo foo | wl-copy" ctrl-v ctrl-c ctrl-v
(the second ctrl-v does not paste because wl-copy was killed).
Work around this for now by running wl-copy asynchronously, and disowning it.
This seems to fix it though I really don't know why. Alternatively we could
"setsid" but that's technically not available on BSD.
For some reason this works in Bash. We should strace it to figure out why.
This introduces a feature flag, "test-require-arg", that removes builtin test's zero and one argument special modes.
That means:
- `test -n` returns false
- `test -z` returns true
- `test -x` with any other option errors out with "missing argument"
- `test foo` errors out as expecting an option
`test -n` returning true is a frequent source of confusion, and so we are breaking with posix in this regard.
As always the flag defaults to off and can be turned on. In future it will default to on and then eventually be made read-only.
There is a new FLOG category "deprecated-test", run `fish -d deprecated-test` and it will show any test call that would change in future.
This seems a bit better because it's what bind uses. To makes sure that
something like :kbd:`ctrl-x` looks good in HTML, remove the border from the
kbd style. Else both "ctrl" and "x" get small boxes which looks weird.
When writing scripts for other shells, it can be confusing and annoying
that our `man` function shadows other manual pages, for example `exec(1p)`
from [Linux man-pages]. I almost never want to see the fish variant for such
contended cases (which obviuosly don't include fish-specific commands like
`string`, only widely-known shell builtins).
For the contented cases like `exec`, the POSIX documentation is more
substantial and useful, since it describes a (sub)set of languages widely
used for scripting.
Because of this I think we should stop overriding the system's man pages.
Nowadays we offer `exec -h` as intuitive way to show the documentation for
the fish-specific command (note that `help` is not a good replacement because
it uses a web browser).
Looking through the contended commands, it seems like for most of them,
the fish version is not substantially different from the system version.
A notable exception is `read` but I don't think it's a very important one.
So I think we should can sacrifice a bit of the native fish-scripting
experience in exchange for playing nicer with other shells. I think the
latter is more important because scripting is not our focus, the way I see it.
So maybe put our manpath at the end.
In lieu of that, let's at least have `exec.rst` reference the system variant.

This is similar to f7dac82ed (Escape separators (colon and equals) to improve
completion, 2019-08-23) except we only escape : and = if they are the result of
file completions. This way we avoid issues with custom completions like dd.
This also means that it won't work for things like __fish_complete_suffix
[*] but that can be fixed later, once we can serialize the DONT_ESCAPE flag.
By moving the escaping step earlier, this causes some unit test changes
which should not result in actual behavior change.
See also #6099
[*]: The new \: and \= does not leak from "complete -C" because that command
unescapes its output -- unless --escape is given.
