The enum starts at 0 (defined to be!), so we can eliminate this one.
That allows us to remove a reliance on the position of
beginning_of_line, and it would trigger a "type-limits" warning.
Also leave a comment because I actually hit that.
Someone has hit the 10MiB limit (and of course it's the number of
javascript packages), and we don't handle it fantastically currently.
And even though you can't pass a variable of that size in one go, it's
plausible that someone might do it in multiple passes.
See #5267.
This widens the remaining ones that don't take a char
anywhere.
The rest either use a char _variable_ or __FUNCTION__, which from my
reading is narrow and needs to be widened manually. I've been unable
to test it, though.
See #5900.
This solves the main part of (careful linebreak)
issue #5900.
I'm betting all the errors that do use narrow IO are broken, including
a bunch of asserts.
This adds a new mechanism for logging, intended to replace debug().
The entry points are FLOG and FLOGF. FLOG can be used to log a sequence of
arguments, FLOGF is for printf-style formatted strings.
Each call to FLOG and FLOGF requires a category. If logging for a category
is not enabled, there is no effect (and arguments are not evaluated).
Categories may be enabled on the command line via the -d option.
Now that our interactive signal handlers are a strict superset of
non-interactive ones, there is no reason to "reset" signals or take action
when becoming non-interactive. Clean up how signal handlers get installed.
The signal handlers for interactive and non-interactive SIGINT were distinct
and talked to the reader. This wasn't really justified and will complicate
having multiple threads. Unify these into a single signal handler.
is_interactive_read is a suspicious flag which prevents a call to
parser_t::skip_all_blocks from a ^C signal handler. However we end
up skipping the blocks later when we exit the read loop.
This flag seems unnecessary. Bravely remove it.
When setting a variable without a specified scope, we should give priority
to an existing local or global above an existing universal variable with
the same name.
In 16fd780484 there was a regression that
made universal variables have priority.
Fixes#5883
Otherwise we'd undo the history search when you press e.g. execute,
which means you'd execute the search term.
Only `cancel` should walk it back, like it previously did hardcoded to
escape.
Fixes#5891.
These were inadvertently disabled by a bug which was introduced in
cd7e8f4103 . Fix the bug so the tests run
again.
They don't all pass yet; they regressed during the period they were
disabled.
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().
This just sets some special characters that we use in the reader, so
it only needs to be done before the reader is set up.
Which, as it stands, is in env_init().
This stops trying to see if the previous line is wider if it is a
prefix of the current one.
Which turns out to be true often enough that it's a net benefit.
This passes character width as an argument for a few functions.
In particular, it hardcodes a width of "1" for a space literal.
There's no reason to compute wcwidth for the length of the prompt.
This measured *all* the characters on the commandline, and saved all
of them in another wcstring_list_t, just to then do... nothing with
that info.
Also, it did wcslen for something that we already have as wcstring,
reserved a vector and did a bunch of work for autosuggestions that
isn't necessary if we have more than one line.
Instead, we do what we need, which is to figure out if we are
multiline and how wide the first line is.
Fixes#5866.
line_shared_prefix explains in its comment that
> If the prefix ends on a combining character, do not include the
previous character in the prefix.
But that's not what it does.
Instead, what it appears to do is to return idx for *every* combining
mark. This seems wrong to begin with, and it also requires checking
wcwidth for *every* character.
So instead we don't do that. If we find the mismatch, we check if it's
a combining mark, and then go back to the previous character (i.e. the
one before the one that the combining mark is for).
My tests found no issues with this, other than a 20% reduction in
pasting time.
