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.
Today, a command like "var=val status " has custom completions
because we skip over the var=val variable override when detecting
the command token.
However if the custom completions read the commandline state (via
"commandline -opc") they do see they variable override, which breaks
them, most likely. Try "a=b git ".
For completions of wrapped commands, we already set a transient
commandline. Do the same for commands with leading variable overrides;
then git completions for "a=b git " will think the commandline is
"git ".
+ Adds a preinstall script to wipe out whatever the last .pkg
installed. This should avoid systems that have mad many updates
getting into strange states autoloading things that no longer
exist. Fixes#2963
+ Run add-shell with ${DSTVOLUME} prepended to the path - the
installer lets users intall onto any volume, so it's plausible
not installed onto /
+ Use `logger` instead of rando /tmp files for logging - stuff
should show up in Console.
+ make_pkg makes the pkg and also fish.app - the former was being
built with -j12 already, make the latter do so as well.
This updates widecharwidth to
6d3d55b419db93934517cb568d1a3d95909b4c7b, which includes the same
Hangul Jamo check in a separate table.
This should slightly speed up most width calculation because we no
longer need to do it for most chars, including the overwhelmingly
common ascii ones.
Also the range is increased and should better match reality.
glibc 2.30 and up emit an ugly depreciation warning on
`#include <sys/sysctl.h>` - this patch makes the build system fail the
include test for `sys/sysctl.h` by forcibly setting `-Werror` before the
call to `check_include_files` (which internally uses `try_compile`) to
get `HAVE_SYS_SYSCTL` to not be defined (even if it's there) if it would
cause such a depreciation message to be emitted.
Ideally, we would not have to manually massage `CMAKE_C_FLAGS` before
calling `check_include_files` and could just tweak that to either always
or conditionally try compilation with `-Werror`, but try_compile doesn't
actually use any overridden `CMAKE_C_FLAGS` values [0] (dating back to
2006).

Remove some nonexistent options (my gcc does not know "-mdata"), fix
the longest description in all of fish and remove some argument
markers from the option.
We apparently vendored it for the sake of attempting to support
old cmake versions:
7aefaff298.
"This file can be dropped once the minimum version of CMake for fish is 3.11.0"
So, drop it like it's hot.
This sets the variable to the background value of
$fish_color_search_match, which fixes the case where you switch from a
theme with a set selected background (like our default, now) to one without.
man(1) uses lowercase placeholders but we usually don't. Additionally,
the new synopsis autoformatting only recognizes placeholders if they
are uppercase. Use uppercase for all placeholders.
Recent synopsis changes move from literal code blocks to
[RST line blocks]. This does not translate well to HTML: it's not
rendered in monospace, so aligment is lost. Additionally, we don't
get syntax highlighting in HTML, which adds differences to our code
samples which are highlighted.
We hard-wrap synopsis lines (like code blocks). To align continuation
lines in manpages we need [backslashes in weird places]. Combined with
the **, *, and `` markup, it's a bit hard to get the alignment right.
Fix these by moving synopsis sources back to code blocks and compute
HTML syntax highlighting and manpage markup with a custom Sphinx
extension.
The new Pygments lexer can tokenize a synopsis and assign the various
highlighting roles, which closely matches fish's syntax highlighing:
- command/keyword (dark blue)
- parameter (light blue)
- operator like and/or/not/&&/|| (cyan)
- grammar metacharacter (black)
For manpage output, we don't project the fish syntax highlighting
but follow the markup convention in GNU's man(1):
bold text type exactly as shown.
italic text replace with appropriate argument.
To make it easy to separate these two automatically, formalize that
(italic) placeholders must be uppercase; while all lowercase text is
interpreted literally (so rendered bold).
This makes manpages more consistent, see string-join(1) and and(1).
Implementation notes:
Since we want manpage formatting but Sphinx's Pygments highlighing
plugin does not support manpage output, add our custom "synopsis"
directive. This directive parses differently when manpage output is
specified. This means that the HTML and manpage build processes must
not share a cache, because the parsed doctrees are cached. Work around
this by using separate cache locations for build targets "sphinx-docs"
(which creates HTML) and "sphinx-manpages". A better solution would
be to only override Sphinx's ManualPageBuilder but that would take a
bit more code (ideally we could override ManualPageWriter but Sphinx
4.3.2 doesn't really support that).
---
Alternative solution: stick with line blocks but use roles like
:command: or :option: (or custom ones). While this would make it
possible to produce HTML that is consistent with code blocks (by adding
a bit of CSS), the source would look uglier and is harder to maintain.
(Let's say we want to add custom formatting to the [|] metacharacters
in HTML. This is much easier with the proposed patch.)
