This will print out along with the stuff we've guessed about color
support. We get a lot of bug reports about these messing up rendering,
this is useful diagnostic output.
Ask the system where utilities are available with confstr (POSIX).
This is the same string printed by `getconf PATH`, which likely
includes more directories.
Expands the utility of `type -p foo` by allowing it to print the path to
the script that defines `foo` when `foo` is a valid function that was
sourced from a path on disk (rather than interactively defined).
This does not change the behavior of `type -P`/`type --force-path`,
which should have already been used if the desire was to resolve the
path to an executable file (otherwise the output would have been blank
if a function was shadowing an executable file of the same namea), so no
backwards compatibility issues are expected.
Using printf like
printf "The message"
is unsafe, because if the message contains any formatting characters,
they'll be interpreted.
In this case it's not all that important because the message contains
only filenames of our tests and static strings, but still.
I was surprised to see:
> set_color normal | string escape
\e\[30m\e\(B\e\[m
I only expected to see a sgr0 here.
Cleanup a nearby `else { if (...) {` and comment with a bogus example.
A person stuck installing it just for fish on their server
doesn't want to waste time installing the wrong one, so assuage that.
Also tweak to look nicer with 80 columns
As discussed in #5492, it would be good if running fish_config without
Python actually told the user to install Python.
Further, let's give the person some hints on how to configure these
things by hand, since they may have to.
I believe this should take care of the reported problem with the
corrected definition for `wcstod_l`. For future reference, any changes
to `config.h.in` should also be reflected in `osx/config.h`
`xlocale.h` is not available on Linux, so we can't just universally
include it.
`HAVE_XLOCALE_H` was already being tested/set in the CMake script as a
possible requirement for `wcstod_l` support, this just adds it to
`config_cmake_h.in` and uses it in `wutil.h` to gate the include.
This was broken in a8eb02f9f5 when the
detection was corrected for FreeBSD. This patch makes the detection work
for both Linux and FreeBSD instead of one or the other (tested).
Using `setlocale` is both not thread-safe and not correct, as
a) The global locale is usually stored in static storage, so
simultaneous calls to `setlocale` can result in corruption, and
b) `setlocale` changes the locale for the entire application, not
just the calling thread. This means that even if we wrapped the
`wcstod_l` in a mutex to prevent the previous point, the results
would still be incorrect because this would incorrectly influence the
results of locale-aware functions executed in other threads while
this thread is executing.
The previous comment mentioned that `uselocale` hadn't worked. I'm not
sure what the failing implementation looked like, but `uselocale` can be
tricky. The committed implementation passes the tests for me under Linux
and FreeBSD.
Don't do it when the relative path is simple (purely descending),
unless the token starts with ":/".
Also stop offering directories - if they need to be disambiguated, the
normal completion logic will take care of that.
Fixes#5574.

If a job is disowned that, for some reason, has a pgid that is special
to waitpid, like 0 (process with pgid of the calling process), -1 (any
process), or our actual pgid, that would lead to us waiting for too
many processes when we later try to reap the disowned processes (to
stop zombies from appearing).
And that means we'd snag away the processes we actually do want to
wait for, which would end with us in a waiting loop.
This is tough to reproduce, the easiest I've found was
fish -ic 'sleep 5 &; disown; set -g __fish_git_prompt_showupstream auto; __fish_git_prompt'
in a git repo.
What we do is to not allow special pgids in the disowned_pids list.
That means we might leave a zombie around (though we probably wait on
0 somewhere), but that's preferable to infinitely looping.
See #5426.
Previously, using special regex characters or slashes would result in an
error message, when pressing tab in a command-line such as
"man /usr/bin/time ".

This was the actual issue leading to memory corruption under FreeBSD in
issue #5453, worked around by correcting the detection of `wcstod_l` so
that our version of the function is not called at all.
If we are 100% certain that `wcstod_l` does not exist, then then the
existing code is fine. But given that our checks have failed seperately
on two different platforms already (FreeBSD and Cygwin/newlib), it's a
good precaution to take.
This broke when --preset was introduced.
We allow a "--preset" or "--user" to appear right after the "bind",
and save the value, but don't use it yet.
Fixes#5534.

PWD is not set in fish vars because it is read only.
Use getenv() to fetch it, allowing fish to inherit a virtual PWD.
This cherry pick includes both:
24f251e04 Correctly remove the test directory again in cd test
91a9c9897 Correctly inherit a virtual PWD

We can't complete these, and now the user can do
```
set -g __fish_git_alias_$alias $command
```
e.g.
```
set -g __fish_git_alias_co checkout
```
if the arguments in the alias end up going to `git alias`.

This was an oversight from the previous commit. Not that it matters
much, because we already removed $files.
Still, this would fail if someone defined a global $files, so let's fix it.
[ci skip]
shorter descriptions that can fit in a terminal window, and option arguments added.
hide one option that is only functional on Cygwin unless we are on Cygwin
Make it so that the generated completion has the form \t\n
when the optional description has been ommitted - otherwise
the original option's description gets inherited and is seen hundreds
of times repeating in the pager.
