C++11 provides std::min/std::max which we're using all over,
obviating the need for our own templates for this.
util.h now only provides two things: get_time and wcsfilecmp.
This commit removes everything that includes it which doesn't
use either; most because they no longer need mini or maxi from
it but some others were #including it unnecessarily.
Hangul uses three codepoints to combine to one glyph. The first has a
width of 2 (like the final glyph), but the second and third were
assigned a width of 1, which seems to match EastAsianWidth.txt:
> 1160..11FF;N # Lo [160] HANGUL JUNGSEONG FILLER..HANGUL JONGSEONG SSANGNIEUN
Instead, we override that and treat the middle and end codepoint as combiners,
always, because there's no way to figure out what the terminal will
think and that's the way it's supposed to work.
If they stand by themselves or in another combination, they'll indeed
show up with a width of 1 so we'll get it wrong, but that's less
likely and not expressible with wcwidth().
Fixes#5729.
This only did prefix matching, which is generally less useful.
All existing users _should_ be okay with this since they want to
provide completions.
Fixes#5467.
Fixes#2318.
This addresses a few places where -Wswitch-enum showed one or two missing
case's for enum values.
It did uncover and fix one apparent oversight:
$ function asd -p 100
echo foo
end
$ functions --handlers-type exit
Event exit
asd
It looks like this should be showing a PID before 'asd' just like
job_exit handlers show the job id. It was falling
through to default: which just printed the function name.
$ functions --handlers-type exit
Event exit
100 asd
This tried to skip conversion if the locale had MB_CUR_MAX == 1, but
in doing so it just entered an infinite recursion (because
writestr(wchar_t*) called writestr(wchar_t*)).
Instead, just let wcstombs handle it.
Fixes#5724.
Since Unicode 9, the width of some characters changed to 2.
Depending on the system, it might have support for it, or it might
not.
Instead of hardcoding specific glibc etc versions, we check what the
system wcwidth says to "😃", U+1F603 "Grinning Face With Big Eyes".
The intention is to, in most cases, make setting $fish_emoji_width
unnecessary, but since it sets the "guessed_emoji_width", that variable still takes precedence if it is set.
Unfortunately this approach has some caveats:
- It relies on the locale being set to a unicode-supporting one.
(C.UTF-8 is unfortunately not standard, so we can't use it)
- It relies on the terminal's wcwidth having unicode9 support IFF the
system wcwidth does.
This is like #5722, but at runtime.
The additional caveat is that we don't try to achieve a unicode
locale, but since we re-run the heuristic when the locale changes (and
we try to get a unicode locale), we should still often get the correct
value.
Plus if you use a C locale and your terminal still displays emoji,
you've misconfigured your system.
Fixes#5722.
Prior to this fix, the wait command used waitpid() directly. Switch it to
calling process_mark_finished_children() along with the rest of the job
machinery. This centralizes the waitpid call to a single location.
It turns out that `string split0` didn't actually ever do any
splitting. The arg_iterator_t already split stdin on NUL, and split0 just
performed an additional search that could never succeed (since
arguments from argv already can't contain NUL).
Let the arg_iterator_t not perform any splitting if asked, and then
let split0 split in 0.
One slight wart is that split0 ignores a trailing NUL, which normal
split doesn't.
Fixes#5701.
This is another case where we used pid when we meant pgroup.
Since 55b3c45f95ba09efa4b9eaad8ec49256a7435823, the assumption that
both are the same no longer holds in all cases, so this check was wrong.
Might fix#5663.
In fish we play fast and loose with status codes as set directly (e.g. on
failed redirections), vs status codes returned from waitpid(), versus the
value $status. Introduce a new value type proc_status_t to encapsulate
this logic.
prettify_node_recursive is replaced with prettify_node_nrecursive
explicite stack is used instead.
