The 0th index of the array was tested inside the loop instead of just
once outside it.
Also explain `input_mapping_is_match` control code behavior and
reasoning and simplify control flow.
Removed misleading statement about read requiring an argument, as the
note about read's new behavior when no arguments are provided covers
that and is less confusing.
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
