If you don't care about file paths containing '=' or ':', you can
stop reading now.
In tokens like
env var=/some/path
PATH=/bin:/usr/local/b
file completion starts after the last separator (#2178).
Commit db365b5ef8 (Do not treat \: or \= as file completion anchor,
2024-04-19) allowed to override this behavior by escaping separators,
matching Bash.
Commit e97a4fab71 (Escape : and = in file completions, 2024-04-19)
adds this escaping automatically (also matching Bash).
The automatic escaping can be jarring and confusing, because separators
have basically no special meaning in the tokenizer; the escaping is
purely a hint to the completion engine, and often unnecessary.
For "/path/to/some:file", we compute completions for "file" and for
"/path/to/some:file". Usually the former already matches nothing,
meaning that escaping isn't necessary.
e97a4fab71 refers us to f7dac82ed6 (Escape separators (colon and
equals) to improve completion, 2019-08-23) for the original motivation:
$ ls /sys/bus/acpi/devices/d<tab>
$ ls /sys/bus/acpi/devices/device:
device:00/ device:0a/ …
Before automatic escaping, this scenario would suggest all files from
$PWD in addition to the expected completions shown above.
Since this seems to be mainly about the case where the suffix after
the separator is empty,
Let's remove the automatic escaping and add a heuristic to skip suffix
completions if:
1. the suffix is empty, to specifically address the above case.
2. the whole token completes to at least one appending completion.
This makes sure that "git log -- :!:" still gets completions.
(Not sure about the appending requirement)
This heuristic is probably too conservative; we can relax it later
should we hit this again.
Since this reverts most of e97a4fab71, we address the code clone
pointed out in 421ce13be6 (Fix replacing completions spuriously quoting
~, 2024-12-06). Note that e97a4fab71 quietly fixed completions for
variable overrides with brackets.
a=bracket[
But it did so in a pretty intrusive way, forcing a lot of completions
to become replacing. Let's move this logic to a more appropriate place.
---
Additionally, we could sort every whole-token completion before every
suffix-completion. That would probably improve the situation further,
but by itself it wouldn't address the immediate issue.
Closes#11027
(cherry picked from commit b6c249be0c)
Mainly to make the next commit's diff smaller. Not much functional
change: since file completions never have the DONT_SORT flag set,
these results will be sorted, and there are no data dependencies --
unless we're overflowing the max number of completions. But in that
case the whole-token completions seem more important anyway.

Commit 798527d79a (completions: fix double evaluation of tokenized
commandline, 2024-01-06) fixed some completions such as the "watchexec"
ones by adding "string escape" here:
set argv (commandline -opc | string escape) (commandline -ct)
This fixed double evaluation when we later call `complete -C"$argv"`.
Unfortunately -- searching for "complete -C" and
"__fish_complete_subcommand" -- it seems like that commit missed some
completions such as sudo. Fix them the same way.
Alternatively, we could defer expansion of those arguments (via
--tokens-raw), since the recursive call to completion will expand
them anyway, and we don't really need to know their value.
But there are (contrived) examples where we do want to expand first,
to correctly figure out where the subcommand starts:
sudo {-u,someuser} make ins
By definition, the tokens returned by `commandline -opc` do not
contain the token at cursor (which we're currently completing).
So the expansion should not hurt us. There is an edge case where
cartesian product expansion would produce too many results, and we
pass on the unexpanded input. In that case the extra escaping is very
unlikely to have negative effects.

We capture the process already, and we use argv by reference for the
other cases.
argv can be big, and this reduces allocations and thereby memory usage
and speed.
E.g. `set -l foo **` with 200k matches has 25% reduced memory usage
and ~5% reduced runtime.
Wgetopt needs a ":" at the beginning to turn on this type of error.
I'm not sure why that is now, and we might want to change it (but tbh
wgetopt could do with a replacement anyway).

And leave the old behavior under the name "cancel-commandline".
This renames "cancel-commandline-traditional" back to
"cancel-commandline", so the old name triggers the old behavior.

Ubuntu Focal calls the package with col "bsdmainutils", which is a
transitional package on newer version of both Debian and Ubuntu.

This needs to be tested more, it has shown issues in MS conhost,
and potentially others.
Changing strategy after beta isn't the greatest idea.
This reverts commit 4decacb933.

I believe this fixes more cases than it breaks. For example
this should fix Termux which seems to be popular among fish
users. Unfortunately I haven't yet managed to test that one.

In all mode, ctrl-k is bind to kill-line.
In Vi visual mode:
* press v or i turn into normal or insert mode respectively.
* press I turn to insert mode and move the cursor to beginning of line.
* because fish doesn't have upcase/locase-selection, and most people reach for
g-U rather than g-u, g-U binds to togglecase-selection temporarily.

The `gcloud` and `gsutil` Google Cloud commands use argcomplete, so integrating them is easy with the `__fish_argcomplete_complete` function.

cursor_selection_mode=inclusive means the commandline position is
bounded by the last character. Fix a loop that fails to account
for this.
Fixes d51f669647 (Vi mode: avoid placing cursor beyond last character,
2024-02-14).
This change looks very odd because if the commandline is like
echo foo.
it makes us try to uppercase the trailing period even though that's
not part of word range. Hopefully this is harmless.
Note that there seem to be more issues remaining, for example Vi-mode
paste leaves the cursor in an out-of-bounds odd position.

Fixes#10980.
This would, if a commandline was given, still revert to checking
the *real* commandline if it was empty.
Unfortunately, in those cases, it could have found a command and tried
to complete it.
If a commandline is given, that is what needs to be completed.
(note this means this is basically useless in completions that use it
like `sudo` and could just be replaced with `complete -C"$commandline"`)
(cherry picked from commit d5efef1cc5)
These are quite mechanical, but include all the commands (as of tmux
3.5a) in the "Windows and Panes" section of `man tmux`. For these
commands, I included the target-pane/session/client/window flags and the
-F formatstring flags (but not the less generic flags specific to
individual commands).
Nice completion is implemented for those flags where the helper
functions were already implemented previously.
After this, tmux pane<tab> will hopefully be useful.
A few TODOs mention low-hanging fruit for somebody who better
understands fish's `complete` command syntax (or a future me).
Another piece of low-hanging fruit would be completion for all the
target-window flags. This PR merely lists them.

Before, it unnecessarily stated that there are three `--style` options, when
there are actually four.
I also align the default `--style=script` argument to the beginning of the line
to match the other options visually for easier scanning.
This can be used to get some information on how fish was built - the
version, the build system, the operating system and architecture, the
features.

If base directories (e.g. $HOME/.config/fish) need to be created,
create them with mode 0700 (i.e. restricted to the owner).
This both keeps the behavior of old fish versions (e.g. 3.7.1) and is
compliant with the XDG Base Directory Specification.
