Reproducer: type `: \<RET><M-p>`. This used to print an error due to builtin test receiving
too many arguments.
It looks like (commandline -j) can return multiple items, because a job can be broken up in multiple
lines terminated by backslashes.
With the new support for self-insert inserting a bound sequence,
the default binding for space as expanding abbreviations can be simplified
to just `self-insert expand-abbr`. This also fixes the bug where space
would cancel pager search.
By not manipulating each line or even each file at a time, we can go
back to `string` and piece together a pipeline that will execute
significantly faster than shelling out to `awk` will. This also removes
one of the few dependencies on `awk` in the codebase.
With this change, `__fish_print_hostnames` now finishes ~80% faster than
it used to a few commits back.
Reordering the `getent hosts` and read from `/etc/hosts` combined with
minimizing shelling and job invocations for parsing the output results
in a profiled and benchmarked ~42% decrease in the time it takes to run,
and that's on a machine with a very small hosts list in the first place.
This update also fixes the hadling of IPv6 addresses in the hosts
output, which were previously ignored, and ignores 127.* loopback
addresses in addition to the 0.0.0.0 address (plus adds support for
shorter IPv4 notations).
$__fish_git_prompt_use_informative_chars will use the informative
chars without requiring informative mode (which is really frickin'
slow!).
See #5726.

This previously effectively checked `string split ' '`s return status,
which was false if it didn't split anything. And while that should be
true if getent fails (because it should produce no output), it's also
true if it doesn't print a line with multiple aliases. Which should be
fairly typical.
Instead we use our new-found $pipestatus to check what getent returns,
in the assumption that it'll fail if it doesn't support hosts.

`getent hosts` is expensive-ish - ~50ms, so we don't want to run it
twice just to figure out it works.
Apparently this works everywhere but CYGWIN and possibly older
OpenBSD, but we don't want to explicitly blacklist those.

If you changed $__fish_git_prompt_show_informative_status, it
triggered a variable handler, which erased the chars, but neglected to
unset $___fish_git_prompt_init, so we just kept chugging along with
empty characters.
What's the hardest thing in CS again? Cache something something?

This way we use our core file completion code, which is much more
flexible than we can easily achieve directly in script (which would
require e.g. an `expand` builtin, and case-insensitive globs).
Fixes#5896.
This was quite famously rather complicated.
We drop a bunch of cases - we can't handle tmux-starting-terminals
100% accurately, so we just don't try. It should be quite rare that
somebody starts a different terminal from tmux.
We drop the `tput` since it is useless (like terminfo in general for
feature-detection, because everyone claims to be xterm).
So we just check if we are in konsole, iTerm, vte or genuine-xterm.
Fixes#3696.
See #3481.
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.
Dealing with macOS output in a fast manner using `string` is surprisingly hard, given that it features lines like
gls(1), ls(1) - list directory contents
Printing the "gls" with the description and the "ls" with the description requires a `while read` loop, and that's too slow.
This reverts commit 7784a5f23c.

I did not realize builtins could safely call into the parser and inject
jobs during execution. This is much cleaner than hacking around the
required shape of a plain_statement.
* Honour `dirprev` scope
Honour the scope of the `dirprev` variable if it is universal
and avoid to shadow it with a global. This enables to share
the `cd` history between sessions.
* Honor dirnext and __fish_cd_direction scope
If these variables exist in the universal scope, do not shadow them
`eval` has always been implemented as a function, which was always a bit
of a hack that caused some issues such as triggering the creation of a
new scope. This turns `eval` into a decorator.
The scoping issues with eval prevented it from being usable to actually
implement other shell components in fish script, such as the problems
described in #4442, which should now no longer be the case.
Closes#4443.
