sys/sysctl.h is deprecated on glibc, so it leads to warnings.
According to fa4ec55c96, it was included for KERN_PROCARGS2 for
process expansion, but process expansion is gone, so it's unused now.
(there is another use of it in common.cpp, but that's only on FreeBSD)
Also 1f06e5f0b9 only included
tokenizer.h (present since the initial commit) if KERN_PROCARGS2
wasn't available, so it can't have been important.
This builds and passes the tests on:
- Archlinux, with glibc 2.30
- Alpine, with musl
- FreeBSD
- NetBSD
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 runs build_tools/style.fish, which runs clang-format on C++, fish_indent on fish and (new) black on python.
If anything is wrong with the formatting, we should fix the tools, but automated formatting is worth it.
- fix the carat position expanding e.g. `command $,`
- improve the error reporting for not-allowed command subtitutions
by figuring out where the expansion failed instead of using
SOURCE_LOCATION_UNKNOWN
- allow nullptr for parse_util_licate_brackets_range() out_string
argument if we don't need it to do any work.
Fixes#5812
This requires threading environment_t through many places, such as completions
and history. We introduce null_environment_t for when the environment isn't
important.
This fixes the `~floam/` case, where the out_tail_idx pointer needs to
point to the "/", not the last letter.
The `~/` and `~floam` cases still work.
Unfortunately, I'm unsure of how to test this.
Fixes#5325.
This switches quoted expansion like "$foo" to use foo's delimiter instead of
space. The delimiter is space for normal variables and colonf or path variables.
Expansions like "$PATH" will now expand using ':'.
This switches fish to a "virtual" PWD, where it no longer uses getcwd to
discover its PWD but instead synthesizes it based on normalizing cd against
the $PWD variable.
Both pwd and $PWD contain the virtual path. pwd is taught about -P to
return the physical path, and -L the logical path (which is the default).
Fixes#3350
Mostly resolves#4862, though there remains the lingering question of
whether or not to emit a warning to /dev/tty or stderr when a
non-literal-zero index evaluates to zero.
