This mainly is conceptually a bit simpler. The comment about making it
cheaper is entirely misplaced since this is quite far away from being
important.
Even expanding 1000 abbrs, it doesn't show up in the profile.
This was, under some circumstances, apparently off by one.
If a suggestion was really long, like
```fish
infocmp | string split , | string trim | string match -re . | while read -d = -l key val; test -z "$val"; and continue; string match -q '*%*' -- $val; and continue; test (string replace -ra '\e([\[\]]|\(B).*[\comJKsu]' '' -- a(tput $key)b) = ab; or echo $key $val; end > xterm
```
(I'm assuming longer than $COLUMNS), it would staircase like with a wrong wcwidth.
This reverts commit 15a5c0ed5f.
I noticed my debug output for 24bit color mode was garbled due to
this being wrong. I spent a little time trying to get the compiler
to tell us about these, but -Wformat doesn't do anything for wchar
printf functions, and __attribute__((format(printf, n, m))) will
cause an error with wchar_t's, so I gave up and decided to manually
check out every '%s' in the entire project. I found (only) one
more.
debug(0, "%s", wchars) will report warnings for incorrect
specifiers but debug(0, L"%s", wchars) is unable. Thus there may
be reason to prefer not using L"..." as an argument if all else
is equal and it's not necessary.
Allows `fish_indent -w **.fish` to restyle all fish files under the
current directory.
(This also has the sideeffect of reducing style.fish time by ~10s, as
we only need to invoke `fish_indent` once, instead of once per-file)
Blocks will soon need to be shared across parsers. Migrate the loop status
(like break or continue) from the block into the libdata. It turns out we
only ever need one, we don't need to track this per-block.
Make it an enum class.
Brace expansion with single words in it is quite useless - `HEAD@{0}`
expanding to `HEAD@0` breaks git.
So we complicate the rule slightly - if there is no variable expansion
or "," inside of braces, they are just treated as literal braces.
Note that this is technically backwards-incompatible, because
echo foo{0}
will now print `foo{0}` instead of `foo0`. However that's a
technicality because the braces were literally useless in that case.
Our tests needed to be adjusted, but that's because they are meant to
exercise this in weird ways.
I don't believe this will break any code in practice.
Fixes#5869.
Prior to this fix, a function_block stored a process_t, which was only used
when printing backtraces. Switch this to an array of arguments, and make
various other cleanups around null terminated argument arrays.
We previously checked if fish_mode_prompt existed as a function, but
that's a bad change for those who already set it to an empty function
to have a mode display elsewhere.
Updated widechar_width takes care of it.
Technically, this does ~3 comparisons more per-character (because it
checks variation selectors and such), but that shouldn't really matter.
get_current_winsize() is intended to be lazy. It does the following:
1. Gets the termsize from the kernel
2. Compares it against the current value
3. If changed, sets COLUMNS and LINES variables
Upon setting these variables, we notice that the termsize has changed
and invalidate the termsize. Thus we were doing this work multiple times
on every screen repaint.
Put back an old hack that just marked the termsize as valid at the end
of get_current_winsize().
