This is fairly subtle.
When installable, and we either can't find the version file or it is
outdated, we ask the user to confirm installation (just like `--install`).
We do that only if we are really truly interactive (with a tty!) to
avoid `fish -c` running into problems.
This check could be tightened even more, because currently:
```fish
fish -ic 'echo foo'
```
asks, while
```fish
fish -ic 'echo foo' < /dev/null
```
does not.
`fish -c` will still error out if it can't find the config, but it
will just run if it is out of date.
Unfortunately it does not appear like #[cfg(test)] works for build.rs?
Investigating a better solution, but this is a good idea anyway (or `make
test` would generate man pages via build.rs!)
This is unfortunately necessary, because otherwise it would not rerun
the build script just because you installed sphinx.
Because we use the man pages for --help output, they're pretty
necessary.
To override it, you can set $FISH_BUILD_DOCS=0, like
```fish
FISH_BUILD_DOCS=0 cargo install --path .
```
fish will print messages for some jobs when they exit abnormally, such as
with SIGABRT. If a job exits abnormally inside the prompt, then (prior to
this commit) fish would print the message and re-trigger the prompt, which
could result in an infinite loop. This has existed for a very long time.
Fix it by reaping jobs after running the prompt, and NOT triggering a
redraw based on that reaping. We still print the message but the prompt is
not executed.
Add a test.

This built on my test system, might be version differences.
(it's also not enough to make it *work*, but a necessary step)
This reverts commit 6fded249cd.
Commit 29dc30711 (Insert some completions with quotes instead of
backslashes, 2024-04-13) wrongly copmletes
$ cat ~/space
to
$ cat '~/path with spaces'
Today completions can be either replacing or appending. We never quote
(but backslash-escape) appending completions (unless they "append"
to an empty token). We always quote replacing completions. The
assumption in this part of the code is that replacing completions
can be quoted without changing meaning.
This assumption is wrong for tildes. For the backslash-escaping code
path, we take care of this edge case via a special DONT_ESCAPE_TILDES
flag. However that flag does not take effect when using quotes for
escaping. Fix that.
Unfortunately, e97a4fab7 (Escape : and = in file completions,
2024-04-19) introduced a (hopefully temporary) code clone in
escape_separators, which made added an extra step to debugging here.
For x86_64 and cross-compiled for aarch64, manually triggered
It *seems* to work, but I had to explicitly disable gettext for it (which is AFAICT currently non-functional under musl anyway).
Also it will create one .zip containing two .tar.xzs. It is about 8MB, which should be fine, tbh.
When built with the default "installable" feature, the data files (share/) are
included in the fish binary itself.
Run `fish --install` or `fish --install=noconfirm` (for
non-interactive use) to install fish's data files into ~/.local/share/fish/install
To figure out if the data files are out of date, we write the current version
to a file on install, and read it on start.
CMake disables the default features so nothing changes for that, but this allows installing via `cargo install`,
and even making a static binary that you can then just upload and have extract itself.
We set $__fish_help_dir to empty for installable builds, because we do not have
a way to generate html docs (because we need fish_indent for highlighting).
The man pages are found via $__fish_data_dir/man
This now allows:
- Same argument (`random 5 5`)
- Swapped ends (`random 10 2`)
- One possibility (`random 0 5 4`)
This makes it easier to use with numbers generated elsewhere instead
of hard-coded, so you don't need to check as much before running it.
Fixes#10879
We don't really care if the process has a custom handler installed, we
can just set it to default.
The one we check is SIGHUP, which may be given to us via `nohup`.
This saves ~30 syscalls *per process* we spawn, so:
```fish
for f in (seq 1000)
command true
end
```
has ~30000 fewer rt_sigaction calls. These take up about ~30% of the
total time spent in syscalls according to strace.
We could also compute this set once at startup and then reuse it.
