In similar vein to how fish_default_key_bindings works, parameters
passed to the function are automatically passed to bind upstream.
Additionally, -s is automatically added if no parameters had been
specified to prevent startup error messages. See 46d1334.
Closes#4494
Drops the % notation for process expansion. The existing notation was a
mess and expanded jobs, process ids, and process names via dark magic.
With this change, % is no longer a special character and can be used
unescaped with impunity.
The variables %self and %last, referring to fish's own pid and the pid
of the last backgrounded job respectively, have been replaced with $pid
and $last_pid. These are read-only variables, protected against being
redefined by the user.
Author's note: I would have personally preferred $fish_pid instead of
$pid but since we debated changing $version to $fish_version and then
reverted that change (with much acrimony), it makes no sense to break
with that precedent here. Additionally, $fish_last_pid is quite wordy.
Closes#4230. Closes#1202.
When number is infinite, not a number, larger than LONG_MAX or smaller
than LONG_MIN, print a corresponding error and return STATUS_CMD_ERROR.
This should fix the worst of the problems, by at least making them clear.
Fixes#4479.
Fixes#4768.
This allows prompts to react to $COLUMNS by e.g. omitting some parts.
We still fallback to a ">" prompt if that's still not short enough,
but now the user has a way of making a nicer prompt.
Fixes#904.
Fixes#4381.
If the head is not a valid, existent command, do not load and run custom
completion sources. This applies to both the autosuggestion provider and
manual user completions. File-based completions will still be offered.
Supersedes #4782 and #4783. Closes#4783. Closes#4782. Closes#2365.
This promotes "and" and "or" from a type of statement to "job
decorators," as a possible prefix on a job. The point is to rationalize
how they interact with && and ||.
In the new world 'and' and 'or' apply to a entire job conjunction, i.e.
they have "lower precedence." Example:
if [ $age -ge 0 ] && [ $age -le 18 ]
or [ $age -ge 75 ] && [ $age -le 100 ]
echo "Child or senior"
end
This fixes a variety of issues related to building the documentation
with CMake. In particular it cleans up the dependency management and
fixes some issues where the documentation build was using generated
files from the source directory.
Now parses package.json and uses results to provide a list of possible
completions to `yarn remove`. There may be other subcommands that could
benefit from this.
Could have parsed yarn output, but yarn is slow and packages.json format
is generally standard since it's machine-generated json.
Can be used to retrieve a list of parent paths, useful for searching
ancestors recursively via their absolute paths. Paths are returned from
deepest to shallowest, starting from the path passed in. Paths are not
validated for performance reasons. (Usually the input to
__fish_parent_directories would be (pwd) or (dir $file).)
This should speed things up on slower PCs given that the vast majority
of shell commands are simple jobs consisting of a single command without
any pipelines, in which case there's no need for a keepalive process at
all. Applies to WSL only.
As a temporary workaround for the behavior described in
Microsoft/WSL#2997 wherein WSL does not correctly assign the spawned
child its own PID as its PGID, explicitly set the PGID for the newly
spawned process.
fish's cmake install routines were attempting to create system
directories that already existed, an operation for which the permissions
to do so may not be available (e.g. /usr/local/share/pkgconfig)
This commit first checks if a directory exists before creating it.
