fish might use XDG_RUNTIME_DIR for the uvar notifier fifo, so this
makes sure that tests are isolated.
Also set permissions to comply with the XDG basedir spec.
This was already printed by builtin_missing_argument/unknown_option.
Since we need more control (because we add our own errors in other
places), teach builtin_unknown_option to suppress the trailer, like
missing_argument already could.
And then use it.
Fixes#8368.
Now looks like
```
Error: Wrong color in test at index 8-11 in text (expected 0x6, actual 0x2):
command echo abc foo &
^^^^
```
instead of repeating the error for every character that is wrong.
This introduces a new variable, $fish_color_option, that can be used
to highlight options differently.
Options are tokens starting with `-`, but only up to (and including!)
the first `--`.
Fixes#8292.
As found by the new translation test, these are the broken format
strings. Using these might cause a crash or garbage read, so it's
reasonably important.
Note that my french is quite rusty and I don't actually speak
swedish (but the related german),
but these seem sensible to me, as there's no real *grammar* as such
involved.
So I feel comfortable enough to fix it instead of removing these
translations entirely.
Fixes#8358
Our tests typically run in their own environment, which is great for
normal tests.
However for the coming translation test, we don't want to copy the .po
files into the test environment, so it's nice to have a way out.
__GLIBC_PREREQ is the preferred way to conditionally enable features
based on glibc versions. Use it to avoid expensive parsing and
locale sensitivity. See #8204
If $xdg_chache_home is empty, this is not a valid fish expression:
[ \( -z \) -o \( ! -d \) ]
and results into an error.
While at it, also use $XDG_CACHE_HOME if that directory does not exist.
This seems better than falling back to $HOME/.cache, which the user has
explicitly overridden via $XDG_CACHE_HOME.
Usually local branches have remote branches with the same name, and in
completion they are currently overshadowed by unique remote branches, making
local branches hard to find. Define local branch completion after unique
remote branch completion to show local branches before unique remote branches.

We want to enable posix_spawn only for glibc >= 2.24, so we check
gnu_get_libc_version() at runtime. This returns a string with the
version number.
Because it's a version number it's spelt with a "." and never a ",",
but we interpret it as a float. This is iffy to begin with, but simple
enough. Only when the locale uses a ",", things break - it'll read it
as "2" and fail the check, which absolutely *tanks* performance on WSL1.
I'm unsure if this gives the proper runtime glibc version - it might,
whereas __GLIBC_MINOR__ and such definitely would not.
So fix the immediate problem by at least using a c locale - this is
already masked by 8dc3982408, but better
safe than sorry.
In 'simple terminal' the delete key prints \e[P by default, which is
related to the different approach the authors of st are taking on the
matter of shell configuration. The main problem is the malfunction of
the delete key, so we have to use a workaround like this.
In most cases, like math, we want C-semantics for floating point
numbers. In particular "." needs to be the decimal separator.
Instead, we pay the price in printf, which is currently the sole place
to output in locale-specific numbers and attempt to read them and
C-style ones.
Similar to `test`, `_` is so likely to at least slow down if not
break all things catastrophically that it ought not be allowed as a
function name. Fixes#8342
