Returns 0 (true) in case an autosuggestion is currently being displayed.
This was first requested in #5000 then again in #10580 after the existing
workaround for this missing functionality was broken as part of a change to the
overall behavior of `commandline` (for the better).
Since we have a mix of both 0-based and 1-based line numbers in the code base,
we can now distinguish between them by type alone. Also stop using 0 as a
placeholder value for "no line number available" except in explicit helper
functions such as `get_lineno_for_display()`.
Both are plenty fast enough, but this way the output of fish_trace isn't
completely taken over by the loops (seems fair since fish_trace probably gets
used rather heavily for completions).
I've often needed a way to get the last bit of performance out of unwieldy
completions that involve a lot of string processing (apt completions come to
mind, and I ran into it just now with parsing man pages for kldload
completions).
Since many times we are looking for just one exact string in the haystack, an
easy optimization here is to introduce a way for `string match` or `string
replace` to early exit after a specific number of matches (typically one) have
been found.
Depending on the size of the input, this can be a huge boon. For example,
parsing the description from FreeBSD kernel module man pages with
zcat /usr/share/man/man4/zfs.4.gz | string match -m1 '.Nd *'
runs 35% faster with -m1 than without, while processing all files under
/usr/share/man/man4/*.4.gz in a loop (so a mix of files ranging from very short
to moderately long) runs about 10% faster overall with -m1.
Preliminary work. Might be important to check version if options I added aren't widely available.
Changed some short options to old-style options since they can't be grouped and don't even need spaces before their arguments, such as `less -ooutputfile` which creates `outputfile`.
The -Dxcolor argument is commented out because its arguments follow complex rules I didn't look into in depth
Part of #1842
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
Part of #1842
It's like jump-to-matching-bracket, but jumps right before the bracket
I will use it to mimic vi 'ab' and 'ib' text objects in the next commit
Given complicated semantics of jump-till-matching-bracket, an alternative name
could be 'jump-inside-matching-brackets'. But that would make names non-symmetrical.
I'm not sure what is worse.
Part of #1842
Split to:
- jump_and_remember_last_jump. What previously was called jump, now called
jump_and_remember_last_jump
- jump. Only jump, don't remember last jump. Now it's also possible to pass
vector of targets
The commit is pure refactoring, no functional changes are introduced.
The refactoring is needed for the next commits
When we changed our default from RelWithDebInfo to Debug, we inadvertently ended
up with all CI building and running in Debug mode. Change at least one of them
back to Release to make sure we don't have any optimizations that cause funky
stuff.
I'm changing the Ubuntu CI image because it's hopefully the fastest (since rust
is relatively dog-slow to compile in release mode).
__fish_apropos is a huge hack under macOS and it seems that it's either broken
or man pages are missing/not indexed under CI. In all cases, hard-code the
results of __fish_describe_command to test the integration machinery
specifically and get the test to pass under macOS CI.
