This would misname `\e\x7F` as "backspace":
bind -k backspace 'do something'
bind \e\x7F 'do something'
because it would check if there was any key *in there*.
This was probably meant for continuous mode, but it simply doesn't
work right. It's preferable to not give a key when one would work over
giving one when it's not correct.
This used to print all codepoints outside of the ASCII range (i.e.
above 0x80) in \uXXXX or \UYYYYYYYY notation.
That's quite awkward, considering that this is about keys that are
being pressed, and many keyboards have actual symbols for these on
them - I have an "ö" key, so I would like to use `bind ö` and not
`bind \u00F6`. So we go by iswgraph.
On a slightly different note, `\e` was written as `\c[ (or \e)`. I do
not believe anyone really uses `\c[` (the `[` would need to
be escaped!), and it's confusing and unnecessary to even mention that.
This used expect_re with a regex ending in `.*`, followed by an
`expect_prompt`.
This meant that, depending on the timing, the regex could swallow the
prompt marker, which caused extremely confusing output like
>Testing file pexpects/generic.py:Failed to match pattern: prompt 14
> ...
> OUTPUT +1.33 ms (Line 70): \rprompt 13>functions\r\nN_, abbr,
> alias, bg, cd, [SNIP], up-or-search, vared, wait\r\n⏎
> \r⏎ \r\rprompt 14>
Yeah - it shows that "prompt 14" was in the output and it can't find
"prompt 14".
I could reproduce the failure locally when running the tests
repeatedly. I got one after 17 attempts and so far haven't been able
to reproduce it with this change applied.
This translated ctrl-k to "\v", which is a "vertical tab", and ctrl-l
to "\f" and ctrl-g to "\a".
There is no "vertical tab" or "alarm" or "\f" *key*, so these
shouldn't be translated. Just drop these and call them `\ck` and such.
(vertical tab specifically is utterly useless and I would be okay with
dropping it entirely, I have never seen it used anywhere)

Yes, this detected escape, waiting *300ms* and then "h" as being below
the escape timeout of 120ms.
Historical behavior is to stop option parsing at the first non-option argument.
Since we have added more options, it seemed impractical to keep that behavior.
However people are using options in their abbr expansions ("abbr e emacs
-nw"). To support this, we ignore options. However, we only ignore them
if they are not valid "abbr" options. Let's ignore all options in the
expansion definition, which is a small price to pay to keep most existing
configurations working.

This does not fix other cases which used to work, like
abbr x -unknown
Those are hopefully not used by anyone, so I don't think we need to maintain
support for that.
Also default the marker to '%'. So you may write:
abbr -a L --position anywhere --set-cursor "% | less"
or set an explicit marker:
abbr -a L --position anywhere --set-cursor=! "! | less"
This renames abbreviation triggers from `--trigger-on entry` and
`--trigger-on exec` to `--on-space` and `--on-enter`. These names are less
precise, as abbreviations trigger on any character that terminates a word
or any key binding that triggers exec, but they're also more human friendly
and that's a better tradeoff.
set-cursor enables abbreviations to specify the cursor location after
expansion, by passing in a string which is expected to be found in the
expansion. For example you may create an abbreviation like `L!`:
abbr L! --position anywhere --set-cursor ! "! | less"
and the cursor will be positioned where the "!" is after expansion, with
the "| less" appearing to its right.
This adds support for the `--function` option of abbreviations, so that the
expansion of an abbreviation may be generated dynamically via a fish
function.
Prior to this change, abbreviations were stored as fish variables, often
universal. However we intend to add additional features to abbreviations
which would be very awkward to shoe-horn into variables.
Re-implement abbreviations using a builtin, managing them internally.
Existing abbreviations stored in universal variables are still imported,
for compatibility. However new abbreviations will need to be added to a
function. A follow-up commit will add it.
Now that abbr is a built-in, remove the abbr function; but leave the
abbr.fish file so that stale files from past installs do not override
the abbr builtin.
Ensure that multiple `-k` completions intermixed with one or more non-`-k`
completions are produced in the expected order with the order of all completions
in a single `-k` completion respected, non-`-k` completions correctly sorted and
interspersed, and the results of multiple `-k` completions in the
reverse-intuitive order (with chronologically later completions coming before
chronologically earlier `-k` counterparts), as per #9221.
This particular variant must be executed as a pexpect test since it relies on
the interactive-only `$history` to trigger the recursion. Note that recursion is
possible via other means (e.g. reading/writing a file), the usage of history
here is just one such example.
When fish runs with job control enabled, it transfers ownership of the
tty to a child process, and then reclaims the tty after the process
exits. If job control is disabled then fish does not transfer or reclaim
the tty.
It may happen that the child process creates a pgroup and then transfers
the tty to it. In that case fish will not attempt to reclaim the tty, as
fish did not transfer it. Then when fish reads from stdin it will
receive SIGTTIN instead of data.
Fix this by unconditionally claiming the tty in readline().
Fixes#9181
This starts two sleep processes and expects them to be killed on
SIGHUP.
Unfortunately, if this ever fails the second run will also fail
because it'll see the old sleep still lying around (because it'll run
for 130 seconds).
So, what we do is:
1. Keep the pids for these specific sleeps
2. Check if any of them are still running (and only fail for them)
3. Kill them from python
Fixes#9152
Curses variables like `enter_italics_mode` are secretly defined to
dereference through the `cur_term` variable. Be sure we do not read or
write these curses variables if cur_term is NULL. See #8873, #8875.
Add a regression test.
Prior to this change, if you tab-completed a token with a wildcard (glob), we
would invoke ordinary completions. Instead, expand the wildcard, replacing
the wildcard with the result of expansions. If the wildcard fails to expand,
flash the command line to signal an error and do not modify it.
Example:
> touch file(seq 4)
> echo file*<tab>
becomes:
> echo file1 file2 file3 file4
whereas before the tab would have just added a space.
Some things to note:
1. If the expansion would produce more than 256 items, we flash the command
line and do nothing, since it would make the commandline overfull.
2. The wildcard token can be brought back through Undo (ctrl-Z).
3. This only kicks in if the wildcard is in the "path component
containing the cursor." If the wildcard is in a previous component,
we continue using completions as normal.
Fixes#954.
