* update nim.fish sample prompt
- Use an helper function to wrap informations
- Add VIRTUAL_ENV infos, if any
- Add __fish_git_prompt, wrapped for the theme
- Add comments
- Remove ASCII failback symbols for tty
(no more useful for me, but if someone really needs it, just ask)
* fish.nim: test -n __fish_git_prompt
Added a new flag `--installed` via `argparse` to `__fish_print_packages`
which indicates that only installed packages should be listed.
TODO: Other non-debian/apt platforms should take advantage of this flag/
behavior as well.
This adds a new string command split0, which splits on zero bytes.
split0 has superpowers because its output is not further split on
newlines when used in command substitutions.
separated_buffer_t encapsulates the logic around discarding (which
was previously duplicated between output_stream_t and io_buffer_t),
and will also encapsulate the logic around explicitly separated
output.
It was only introduced in 2.16, which was released in January 2018.
Instead, we just use a bare "--ignored", which is equivalent to "--ignored=traditional".
The difference to "--ignored=matching" mode shouldn't matter to us here.
Fixes#5074.
Executes `whatis` safely, returns at most one line, and strips the name
of the command from the start of line, returning a value fit for use as
the description parameter for a completion argument value.
Fixes
- Use the actual path when skipping unusable paths to fix all Include
directives being skipped when there is no ~/.ssh directory
- Prevent "No matches for wildcard" message
Improvements
- Skip paths that are directories since we only want files
- Remove `cd` as it is not needed
__fish_complete_suffix assumed that the only literal . in a path
would be the . before an extension, and stripped accordingly. This
behavior has been there for a long time, but broke many things
including completion of relative paths and completion of paths with
a literal . in a directory name.
__fish_complete_suffix does not just complete extensions (or at the
very least, it no longer does just that) but rather any suffix, so
isolating the path name without the extension was unnecessary in all
cases.
If just one of the range ends is negative, this now forces direction away from it.
I.e. if the beginning is negative, we go in reverse.
If the end is negative, we go forwards.
This fixes cases like
$var[2..-1]
if $var only has one element.
I'm not sure what was wrong with the old syntax, but I needed to switch
the outer quotes to ' and the inner quotes to " in order for the
completions to work when they weren't explicitly sourced.
Additionally, realized that the overload for __fish_complete_suffix can
be used to get the filtered list of kernel modules from /boot/kernel in
the initial run.
Allows the most painful of curl's arguments to be completed by fish by
restoring file-based completions for paths prefixed with `@` (which are
typically used after parameters like --data).
With a blank $suff (i.e. complete all files), __fish_complete_suffix
returned directories twice, once with the trailing `/` and once without.
This fixes that, and additionally speeds up the code by no longer
shelling out to `sort -u` as we no longer rely on brace expansion to
enumerate directories and files simultaneously.
In general, this behavior would occur when a directory exists that
matches the suffix search pattern (so a dir named 'foo.bar' with a
search pattern '.bar' would return 'foo.bar' twice).
Runtime has dropped from ~22ms to ~8ms on my machine, while also
returning more correct results.
Default to RelWithDebInfo (-O2 -g) if no custom CMAKE_BUILD_TYPE is
defined. Also add flags for use with CMAKE_BUILD_TYPEs Debug, Release,
and RelWithDebInfo.
While supported by gcc and clang, \e is a gcc-specific extension and not
formally defined in the C or C++ standards.

We've tried numerous approaches to mitigate the race condition between
`posix_spawn` and the `setpgid` call, but unfortunately due to the flags
we pass to `posix_spawn`, it (rarely? never?) results in `vfork()` being
used, which means it is never executed atomically. Since it is executed
out-of-band, we must manually call `setpgid` in case `posix_spawn`
hasn't gotten around to doing that yet, but in the event that it has, an
EACCES error can be returned.
Closes#4884. Closes#4715. See also #4778.
On systems where the terminfo for TERM does not contain a string for
attributes such as enter_underline_mode, etc. fish was crashing with a
fatal error message and a note to email the developers.
These are non-essential text attribute changes and should not trigger
such a failure.
