Given "1(23)4", this function returns an inclusive range, from the opening
to the closing parenthesis. The subcommand is extracted by incrementing
the range start and interpreting the result as an exclusive range.
This is confusing, especially if we want to add multi-character quotes.
Change it to always return the full range (including parentheses) and provide
an easy way to access the command string.
While at it, switch to returning an enum.
This change is perhaps larger and more complex than necessary (sorry)
because it is mainly made with multi-character quotes in mind. Let's see
if that works out.
In addition to the native Emacs undo binding, we also support ctrl-z.
On Linux, ctrl-shift-z alias ctrl-Z is the redo binding according to
https://en.wikipedia.org/wiki/Table_of_keyboard_shortcuts Let's bind allow
that.
Unfortunately ctrl-shift and ctrl-alt modified shortcuts on Linux may be
intercepted by the windowing system or the terminal. Only alt-shift seems to be
available reliably (but the shift bit should mean "extend selection" in Emacs).
This removes IsOkAnd and the is_some_and method.
I cannot actually find is_none_or in the stdlib?
I've kept the trait name to avoid changing it now and then later, maybe this should
be moved elsewhere to avoid claiming it's an stdlib thing?
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

vared.fish is installed at

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").

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.
