Let's hope this doesn't causes build failures for e.g. musl: I just
know it's good on macOS and our Linux CI.
It's been a long time.
One fix this brings, is I discovered we #include assert.h or cassert
in a lot of places. If those ever happen to be in a file that doesn't
include common.h, or we are before common.h gets included, we're
unawaringly working with the system 'assert' macro again, which
may get disabled for debug builds or at least has different
behavior on crash. We undef 'assert' and redefine it in common.h.
Those were all eliminated, except in one catch-22 spot for
maybe.h: it can't include common.h. A fix might be to
make a fish_assert.h that *usually* common.h exports.
Intern'd strings were intended to be "shared" to reduce memory usage but
this optimization doesn't carry its weight. Remove it. No functional
change expected.
ESCAPE_ALL is not really a helpful name. Also it's the most common flag.
Let's make it the default so we can remove this unhelpful name.
While at it, let's add a default value for the flags argument, which helps
most callers.
The absence of ESCAPE_ALL makes it only escape nonprintable characters
(with some exceptions). We use this for displaying strings in the completion
pager as well as for the human-readable output of "set", "set -S", "bind"
and "functions".
No functional change.
If the completion pager renders as
foo1 bar1 baz1 qux1
foo2 bar2 baz2
foo3 bar3 baz3
and we go backwards from "foo1" (using left arrow), we'll end up at "baz3",
not "qux1". Pretty smart!
If however we go backwards once more, nothing happens.
The root cause is that there are two different kinds of selection indices:
the one before rendering (9/qux1) and the one after we cleverly subtract
the half-filled last column (8/baz3). The backwards movement ends up
decrementing the first, so it moves from 9 to 8 and nothing changes in
the rendering.
Fix this by using the selection index that we actually rendered.
There is another caller that relies on the old behavior of using the unrendered
selection index. Make it use a dedicated overload that does not depend on
the rendering.
This migrates our PCRE2 dependency from builtin/string.cpp to new files
re.h/re.cpp, allowing regexes to be used in other places in fish.
No user-visible behavior change expected here.
Resolves this warning:

This makes it so `complete -c foo -n test1 -n test2` registers *both*
conditions, and when it comes time to check the candidate, tries both,
in that order. If any fails it stops, if all succeed the completion is offered.
The reason for this is that it helps with caching - we have a
condition cache, but conditions like
```fish
test (count (commandline -opc)) -ge 2; and contains -- (commandline -opc)[2] length
test (count (commandline -opc)) -ge 2; and contains -- (commandline -opc)[2] sub
```
defeats it pretty easily, because the cache only looks at the entire
script as a string - it can't tell that the first `test` is the same
in both.
So this means we separate it into
```fish
complete -f -c string -n "test (count (commandline -opc)) -ge 2; and contains -- (commandline -opc)[2] length" -s V -l visible -d "Use the visible width, excluding escape sequences"
+complete -f -c string -n "test (count (commandline -opc)) -ge 2" -n "contains -- (commandline -opc)[2] length" -s V -l visible -d "Use the visible width, excluding escape sequences"
```
which allows the `test` to be cached.
In tests, this improves performance for the string completions by 30%
by reducing all the redundant `test` calls.
The `git` completions can also greatly benefit from this.
This can no longer be changed. If "no-stderr-nocaret" is in
$fish_features it will simply be ignored.
The "^" redirection that was deprecated in fish 3.0 is now gone for good.
Note: For testing reasons, it can still be set _internally_ by running
"feature_flags_t::set". We simply shouldn't do that.

The box drawing because it's entangled with the rest and we don't
currently use this anywhere I know of. Nor was it gated on terminfo,
so it could have broken things, for subjectively little gain.
Fixes#8727.
The previous commit added transient commandlines when completing
commands with variable overrides. Transient commandlines require a
parser, but perform_one_completion_cd_test() asked for completions
without giving a parser, which is only okay when asking for
autosuggestions (like perform_one_autosuggestion_cd_test() does).
Let's pass a parser to fix the test.
The sole notifiers test recreated the uvar directory, so if it was
called while the universal test was running it would stop it from
completing correctly.
This happened reasonably often on Ubuntu with tsan on Github Actions.
Cygwin tests are failing because cygwin has a low limit of only 64 fds in
select(). Extend select_wrapper_t to also support using poll(), according to
a FISH_USE_POLL new define. All systems now use poll() except for Mac.
Rename select_wrapper_t to fd_readable_set_t since now it may not wrap
select().
This allows the deep-cmdsub.fish test to pass on Cygwin.
This unit test was passing 0 instead of a pointer to indicate the end of
a varargs; this might fail on 64 bit, and indeed did fail on Cygwin. This
fixes the Cygwin expand test.
A variable may be broken across multiple lines with a backslash, for
example:
> echo $FISH_\
VERSION
Teach syntax highlighting about this line breaking. Fixes#8444
+ No functional change here, just renames and #include changes.
+ CMake can't have slashes in the target names. I'm suspciious of
that weird machinery for test, but I made it work.
+ A couple of builtins did not include their own headers, that
is no longer the case.
Now looks like
```
Error: Wrong color in test at index 8-11 in text (expected 0x6, actual 0x2):
command echo abc foo &
^^^^
```
instead of repeating the error for every character that is wrong.
This introduces a new variable, $fish_color_option, that can be used
to highlight options differently.
Options are tokens starting with `-`, but only up to (and including!)
the first `--`.
Fixes#8292.
