Arrow keys are often not conveniently located on keyboards, so the use of arrow keys for common keyboard shortcuts can be a turn-off for some.
I found that fish supports alternate keybindings for these cases but I didn't seem them documented in these places where the arrow keys versions are highlighted.
Meaning empty variables, command substitutions that don't print
anything.
A switch without an argument
```fish
switch
case ...
end
```
is still a syntax error, and more than one argument is still a runtime
error.
The none-argument matches either an empty-string `case ''` or a
catch-all `case '*'`.
Fixes#5677.
Fixes#4943.
This test uses universal variables, and so it can fail when run
multiple times.
It might be a good idea to do this in general, but for now let's just
try it here.
See for example: https://git-scm.com/docs/git-cherry
git cherry is quite helpful when trying to findout if merges between
branches are complete, when there were cherry-picks in addition to
merges.
Previously when propagating explicitly separated output, we would early-out
if the buffer was empty, where empty meant contains no characters. However
it may contain one or more empty strings, in which case we should propagate
those strings.
Remove this footgun "empty" function and handle this properly.
Fixes#5987
Prior to this fix, fish would attempt to react if a local fish_complete_path
or fish_function_path were set. However this has never been very well tested
and will become impossible with concurrent execution. Always use the global
values.
Soon we will have more complicated logic around whether to call tcsetpgrp.
Prepare to centralize the logic by passing in the new term owner pgrp,
instead of having child_setup_process perform the decision.
I tested this manually (`littlecheck.py -s fish=fish tests/checks/eval.fish`) from the base directory, which means I got
"tests/checks/eval", while the real test gets "checks/eval".
I then reran `make test_fishscript`, but that didn't pull in the
updated test - we should really handle that better.
This exitted if the cursor was at the end of the line as well (i.e. if
delete-char failed). That's a bit too eager.
Also documentation, which should have already been included.
I'm gonna add more tests to this and I don't want to touch the old stuff.
Notice that this needs to have the output of the complete_directories
test adjusted because this one now runs later.
That's something we should take into account in future.
