scp completions use "ls" to list files on the remote host. If a user aliases
them (in noninteractive shells) this will break. In general, this is the
users fault but also kind of ours because we shouldn't really use "ls" here.
Let's work around this problem by skipping functions.
Fixes#9363
Implement completion for vim tags from any place within the source tree.
To prevent freezes on a huge tags file (e.g., on one from the Linux
kernel source tree), amount of completion lines is limited to 10000.
Note that the TAGS file (EMACS-compatible tags file) is not searched
here as it would not be used by vim anyway.
flatpak completions gate some features behind checks like
test $flatpakversion -gt 1.2
which does a floating point comparison, which is different
from version comparison.
Most of these version checks are irrelevant anyway because they check for
a version that's not even in Debian oldstable. The only one that might be
relevant is a check for version 1.5 but that only gates some extra subcommands;
there's little harm in providing them too.
So let's just remove the version check.
Hopefully fixes#9341 (untested)
Note that flatpak upstream provides a completion file too - but it's shadowed
by ours on my system. This is a tricky issue for another day.
Previously an environment variable to redefine would only be suggested if you
had not yet started typing one out. This makes it so that `env C<TAB>` will also
complete to, for example, [ `CC=`, `CXXFLAGS=`, ... ].
It also is smarter when suggesting variable names to complete: if a variable has
already been completed, it isn't suggested again. Additionally, it only suggests
names for variables that are exported, not all variables (the previous list was
insanely long and including things like all our `fish_...` variables).
Update completions for the tree command. There are a lot of new options
were added since the 1.6.0 release (which apparently was used to create
current completions).
Options are also reordered to follow the "tree" help.
Adds a few options I see in my git manpage that were omitted:
-v, -h, -P, --config-env, --no-optional-locks, --list-cmds
Reword most general option descriptions
Simple way to make the apt completions spew:
function apt; end
on a system without an apt command installed. (even if it isn't
Darwin, because this uses test combiners!)
This is a thing some people do to avoid learning other package managers.
(of course our completions would probably be *wrong* still, but at least they
won't spew a `test` error)
The 'str' variable was apparently mistakenly removed by 49c5f96470.
Re-add it, and regex-escape it as well.
Allow completing on apropos <TAB> instaed of requiring an initial char.
Use __fish_apropos instead of apropos.
New regex to hopefully work on more platforms.
Explicitly use ^ instead of adding it at __fish_apropos
None of these __functions defined in completions are used or
referenced anywhere.
Found with:
function unused -a file search -d 'find unused functions'
set -f (string replace -fr '^[\s]*function ([\w_]+).*' '$1' < $file)
for cmd in $cmds
printf %d\ %s\n (grep -r ".*$cmd.*" $search < $argv | count) $cmd
end | string match '1 *'
end
for file in share/*/*.fish
unused $file share && printf "in %s\n" $file
end
Get rid of functions:
__fish_git_diff_opt,
__fish__git_append_letters_nosep,
__fish_git_sort_keys
Use `set -f` inside blocks instead of `set -l foo` before blocks.
Two of these just printed out the argument\tdescription dictionaries
without providing any utility: only used once, just do it inline.
Collapse adjacent lines that look like
complete git -n '(blah)' -l option -d 'option help'
complete git -n '(blah)' -l option -a 'arg1' -d 'description 1'
complete git -n '(blah)' -l option -a 'arg2' -d 'description 2'
complete git -n '(blah)' -l option -a 'arg2' -d 'description 3'
...
into
complete git -n '(blah)' -l option -d 'option help' -a "
arg1\t'description 1'
arg2\t'description 2'
arg3\t'description 3'
..."
This sped up the source time about 10% by running complete
less.
In the presence of modified files, assume `git checkout ...` is being
invoked/completed with the intention of restoring modifications. Even if not the
case, this list is likely going to be shortest if someone is about to change
branches.
Afterwards, list branches (with local branches sorted by recency), then remote
unique remotes, heads, tags, and recent commits. The order of these last four
is up for debate, and honestly if any of them generate a lot of results it makes
finding what you're actually looking for in the autocompletions a lot harder.
It may be better to merge these last contenders and sort them by individual
recency instead, but that does make the pager entries rather messy (and we would
need to add a new function to do that in order to interleave them in the desired
sort order but preserve the overall sort after the completions subshell
terminates).
