This gave a weird error when you did e.g. `math Foo / 6`:
"Missing Operator" and only the "F" marked.
Adding an operator here anywhere won't help, so calling this an
"Unknown function" is closer to the truth. We also get nicer markings
because we know the extent of the identifier.
Fix 7308dbc7a (fish_indent: Prevent overwriting file with identical content,
2024-07-21) in a different way by passing O_TRUNC again.
If we don't want regressions we could use code review.
When `manpath` prints a symlink to a directory, `/usr/libexec/makewhatis`
ignores the entire directory:
```
$ /usr/libexec/makewhatis -o /tmp/whatis \
(/usr/bin/manpath | string split :)
makewhatis: /Users/wiggles/.nix-profile/share/man: Not a directory
```
This means that the built-in `man` completions will not index any commands in
these directories.
If we pass the directories to `readlink -f` first, `makewhatis` correctly
indexes the `man` pages.
```
$ /usr/libexec/makewhatis -o /tmp/whatis \
(/usr/bin/manpath | string split : | xargs readlink -f)
```
We used deque in C++ because this vector may be large, and so it avoids
repeated re-allocations. But VecDeque is different in Rust - it's contiguous -
so there's no benefit. Just use Vec.
For implementation reasons, we special-case cd in several ways
1. it gets different completions (handle_as_special_cd)
2. when highlighting, we honor CDPATH
3. we discard autosuggestions from history that don't have valid path arguments
There are some third-party tools like zoxide that redefine cd ("function cd
--wraps ...; ...; end"). We can't support this in general but let's try to
make an effort.
zoxide tries to be a superset of cd, so special case 1 is still
valid but 2 and 3 are not, because zoxide accepts some paths
that cd doesn't accept.
Let's add a hack to detect when "cd" actually means something else by checking
if there is any --wraps argument.
A cleaner solution is definitely possible but more effort.
Closes#10719
fish adds ~/.local/share/fish/man to its MANPATH for builtins etc. But pages
like fish-doc are unambiguous so it seems like they should be accessible
from outside fish by default.
Closes#10711
In some cases we add the wildcard twice.
$ fish -c '../jj; complete -C"ls cli/*/conf/tem"'
cli/*/*/config/templates.toml
Fix that. Test in the next commit.
There seems to be another bug in 3.7.1 where we fail to apply this completion
to the command line. This appears fixed. (FWIW we might want to revert
the quoting change in completion_apply_to_command_line(), maybe that one
accidentally fix this).
Fixes#10703
The HashMap is used to generate the __fish_describe_command integration
completions. Given the nature of the allocations and the numbers that we use, a
BTreeMap would theoretically perform better. Benchmarks show a 2-9%
improvement in completion times consistently in favor of BTreeMap.
Warnings were appearing under GCC 13.2
(void) alone is insufficient under modern compilers, workaround with logical

Worth including because mold is rather popular in the rust world and because the
bug affects mold versions coincident with the development of the fish rust port.
The bug affects all currently released versions of mold from 2.30.0 (Mar 2024)
onwards under at least FreeBSD (though quite likely other platforms as well).
See https://github.com/rui314/mold/issues/1338 for reference.
We keep having to extend these with new terminals, and I can no longer
find a terminal that fails this.
Even emacs' ansi-term can now at least reliably ignore the sequence.
- the __fish_seen_any_argument function did not work
- the xxd_exclusive_args specification was not correct
- longer old-style options were missing
- technically short options are also old-style options in xxd
- some options were missing
Static linking against glibc has crashes depending on the name
resolution setup (I think when it needs to dlopen). It is a fundamental glibc
limitation that we cannot fix on our end.
It will crash when doing `echo ~<TAB>`.
This carves out a specific exception for "gnu", i.e. glibc, targets.
Other targets, including musl and other operating systems, continue to
allow static linking.
The previous control flow logic wasn't sound and would leave the shell in a hung
state when `break` would be encountered.
The behavior is now straightforward, the shell reads until <Enter> or <q> is
pressed, at which point it aborts.
This was based on a misunderstanding.
On musl, 64-bit time_t on 32-bit architectures was introduced in version 1.2.0,
by introducing new symbols. The old symbols still exist, to allow programs compiled against older versions
to keep running on 1.2.0+, preserving ABI-compatibility. (see musl commit 38143339646a4ccce8afe298c34467767c899f51)
Programs compiled against 1.2.0+ will get the new symbols, and will therefore think time_t is 64-bit.
Unfortunately, rust's libc crate uses its own definition of these types, and does not check for musl version.
Currently, it includes the pre-1.2.0 32-bit type.
That means:
- If you run on a 32-bit system like i686
- ... and compile against a C-library other than libc
- ... and pass it a time_t-containing struct like timespec or stat
... you need to arrange for that library to be built against musl <1.2.0.
Or, as https://github.com/ericonr/rust-time64 says:
> Therefore, for "old" 32-bit targets (riscv32 is supposed to default to time64),

However, while fish runs on i686 and compiles against pcre2, we do not pass pcre2 a time_t.
Our only uses of time_t are confined to interactions with libc, in which case with musl we would simply use the legacy ABI.
I have compiled an i686 fish against musl to confirm and can find no issue.

Add kqueue-based uvar notifier for BSD
Tested under FreeBSD 13.3.
This also works under all versions of macOS, and has some
benefits over the current notifyd choice.
Mutex is used because of the non-mut `notification_fd_became_readable()` `&self`
reference, but contention is not expected.
