According to the discussion in #2315, we adopt TTY modes for external commands
mainly for "stty". If our child process crashes (or SSH disconnect), we
might get weird modes. Let's ignore the modes in the failure case.

The implementation is obviously isn't 100% vi compatible, but works good enough
for major cases
This commit depends on previous commits where jump-{to, till}-matching-bracket
motions were introduces
Add round options, but I think can also add floor, ceiling, etc. And
the default mode is trunc.

Reminder that reStructuredText is awkward and you can't make sphinx treat these
as inline code; they'll be formatted as italic text only.
Vim search expression:
\([`:]\)\@<!`[^`:]\+`\(`\)\@!
Followed by
ysi``
does the trick quite nicely.
As reported on gitter, commands like "rm (...)" sometimes want a previous
command inside the parentheses. Let's try that. If a user actually wants
to search for a command substitution they can move the cursor outside the
command substitution, or type the search string after pressing ctrl-r?
In addition to the native Emacs undo binding, we also support ctrl-z.
On Linux, ctrl-shift-z alias ctrl-Z is the redo binding according to
https://en.wikipedia.org/wiki/Table_of_keyboard_shortcuts Let's bind allow
that.
Unfortunately ctrl-shift and ctrl-alt modified shortcuts on Linux may be
intercepted by the windowing system or the terminal. Only alt-shift seems to be
available reliably (but the shift bit should mean "extend selection" in Emacs).
After abandoning a commandline (for example with ctrl-c) it's nice to be
able to restore it. There is little reason to discard the requisite undo
information, so keep it.
Try to keep the "backwards-incompatible" section reasonably short so
people can get a quick overview of what they need to handle.
So we split the "bind" part into two.
wl-copy is a daemon process that serves its stdin to any wl-paste processes.
On Wayland, we launch it from fish_clipboard_copy. It then lives in the
same process group as fish (see `ps -o pid,pgid,comm`).
For some reason pressing ctrl-c inside the VSCode integrated terminal with
fish as the default shell kills the wl-copy process, thus clearing the
clipboard. On other terminals it works fine.
This is also reproducible by running "echo foo | wl-copy" ctrl-v ctrl-c ctrl-v
(the second ctrl-v does not paste because wl-copy was killed).
Work around this for now by running wl-copy asynchronously, and disowning it.
This seems to fix it though I really don't know why. Alternatively we could
"setsid" but that's technically not available on BSD.
For some reason this works in Bash. We should strace it to figure out why.
This seems a bit better because it's what bind uses. To makes sure that
something like :kbd:`ctrl-x` looks good in HTML, remove the border from the
kbd style. Else both "ctrl" and "x" get small boxes which looks weird.
This is similar to f7dac82ed (Escape separators (colon and equals) to improve
completion, 2019-08-23) except we only escape : and = if they are the result of
file completions. This way we avoid issues with custom completions like dd.
This also means that it won't work for things like __fish_complete_suffix
[*] but that can be fixed later, once we can serialize the DONT_ESCAPE flag.
By moving the escaping step earlier, this causes some unit test changes
which should not result in actual behavior change.
See also #6099
[*]: The new \: and \= does not leak from "complete -C" because that command
unescapes its output -- unless --escape is given.
alt-d used to do that until evil merge[*] 213e90704 (Merge remote-tracking branch
'upstream/master' into bind_mode, 2014-01-15) which changed the order of
the \ed bindings such that the smart dirh version would be shadowed by the
simpler ones.
[*] git blame alone failed to find it because it skips merge commits.
We sometimes leak ^[[I and ^[[O focus reporting events when run from VSCode's
"Run python file" button in the top right corner. To reproduce I installed
the ms-python extension set the VSCode default shell to fish and repeatedly
ran a script that does "time.sleep(1)". I believe VSCode synthesizes keys
and triggers a race condition.
We can probably fix this but I'm not sure when I'll get to it (given how
relatively unimportant this feature is).
So let's go back to the old behavior of only enabling focus reporting in tmux.
I believe that tmux is affected by the same VSCode issue (also on 3.7.1 I
think) but I haven't been able to get tmux to emit focus reporting sequences
yet. Still, keep it to not regress cursor shape (#4788). So far this is
the only motivation for focus reporting and I believe it is only relevant
for terminals that can split windows (though there are a bunch that do).
Closes#10448
This is another problem that has been bothering me for years: as mentioned
in 1dd901e52 (Maintain cursor in history prefix search, 2024-04-12), up-arrow
search highlights search matches but the contrast is really bad, especially in
command position, because the search matches --background=brblack is combined
with whatever foreground syntax highlighting the command has. The history
pager had a similar problem (for the selected history item) but circumented
it by disabling syntax highlighting altogether for the selected item.
fish_color_search_match's foreground component is ignored.
Let's use it instead of syntax highlighting.
This fixes the contrast on some default colorschemes but the bryellow
foreground looks weirdly like an error/warning on some terminals. Change it
to white. This needs a hack because we don't have a canonical way to tell
if a uvar has been set by the user. Fortunately the foreground component
hasn't been used at all so far, so we're not so much changing it as much as
initializing it.
Indented multiline commandlines look ugly in an external editor. Also,
fish doesn't properly handle the case when the editor runs fish_indent.
Fix is by indenting when exporting the commandline and un-indenting when
importing the commandline again.
Unindent only if the file is properly indented (meaning at least by the
amount fish would use). Another complication is that we need to offset
cursor positions by the indentation.
This approach exposes "fish_indent --only-indent" and "--only-unindent"
though I don't imagine they are useful for others so I'm not sure if this
is the right place and whether we should even document it.
One alternative is to add "commandline --indented" to handle indentation
transparently.
So "commandline --indented" would print a indented lines,
and "commandline --indented 'if true' ' echo'" would remove the unecessary
indentation before replacing the commandline.
That would probably simplify the logic for the cursor position offset.
