This is the last remnant of the old percent expansion.
It has the downsides of it, in that it is annoying to combine with
anything:
```fish
echo %self/foo
```
prints "%self/foo", not fish's pid.
We have introduced $fish_pid in 3.0, which is much easier to use -
just like a variable, because it is one.
If you need backwards-compatibility for < 3.0, you can use the
following shim:
```fish
set -q fish_pid
or set -g fish_pid %self
```
So we introduce a feature-flag called "remove-percent-self" to turn it
off.
"%self" will simply not be special, e.g. `echo %self` will print
"%self".
This stops you from doing e.g.
```fish
set pager command less
echo foo | $pager
```
Currently, it would run the command *builtin*, which can only do
`--search` and similar, and would most likely end up printing its own
help.
That means it very very likely won't work, and the code is misguided -
it is trying to defeat function resolution in a way that won't do what
the author wants it to.
The alternative would be to make the command *builtin* execute the
command, *but*
1. That would require rearchitecting and rewriting a bunch of it and
the parser
2. It would be a large footgun, in that `set EDITOR command foo` will
only ever work inside fish, but $EDITOR is also used outside.
I don't want to add a feature that we would immediately have to discourage.
Currently, if you enter `echo` and press up-arrow, it might select
e.g. `echo foo`.
You can then enter text, making it `echo foobar` and press up-arrow
again, but the search string is *still* `echo`.
Many *other* input functions will end history search, including e.g.
expand-abbr, so pressing space by default will already end it.
So this ends the history search once you input something.
Incidentally this allows suggestions to work in this case, so it
Fixes#10287
Note that autosuggestions have been disabled while history search is
active since a08450bcb6, I'm not sure
it's actually *needed*, so it would also be possible to enable it in
that case.
But since this is already awkward (history search is *active* but with
the old search string) and I'm not sure if e.g. suggestions during
history search would be too busy, let's do this first.
With LTO, Release builds are now a lot slower.
For development debug builds are much nicer.
We'll ask packagers to pass Release when building a package.
Unfortunately ninja does not want to be tricked.
I tried `touch`ing a file and writing the date to a file,
and even removing that file before cargo runs, it doesn't work.
So instead we'll do the imperfect solution of enumerating sources.
And yes, we use a GLOB because listing source files is terrible.
Any build system that wants you not to glob is a build system made for
build system people who like touching build systems, not me.
The default codegen units is 16 but we set it to 1*. On my system, this
saves 0.1 MB (2%) in the unstripped binary, while adding 10s (20%) to the
build time. This doesn't seem worth, better stick to the defaults.
[*] along enabling fat LTO which is debatable too
gpg's --use-embedded-filename is a dangerous option that can cause gpg
to write arbitrary content to arbitrary files.
According to the GnuPG maintainer, this is not an option recommended
for use (https://dev.gnupg.org/T4500). Fish shouldn't encourage users
to supply it.
I've offered https://dev.gnupg.org/T6972 to upstream to make it even
more clear that this option is a bad idea.
While removing it, we might as well also remove
--no-use-embedded-filename, since it is effectively a no-op.
This reduces the test time by ~33% on my system (23s to 15s)
Given that it takes ~180-240s on Github Actions, if we get a reduction
like that we can save over a minute.
These are dog-slow at building, and the tests themselves are barely
sped up running as release.
Given that we have ~10 minute build and ~3 minute test time on Github
Actions on macOS, let's see if this speeds it up
(we can also do it for the others, but the most important is the
slowest test because that's what stops the checkmark appearing)
We only use this
1. if we have localeconv_l
2. to get the decimal point / thousands separator for numbers
So we can ignore all this and directly create a purely LC_NUMERIC locale.
This *was* more useful when we were in C++ and the printing functions
all relied on locale, but we only use this in printf and that only
extracts the number stuff.
Commit b768b9d3f (Use fuzzy subsequence completion for options names as well,
2024-01-27) allowed completing "oa" to "--foobar", which is a false positive,
especially because it hides other valid completions of non-option arguments.
Let's at least require a leading dash again before completing option names.
The lines of code I commented on in #10254 were meant to serve only as examples
of the changes I was requesting, not the only instances.
Also just use `Mode::from_bits_truncate()` instead of unsafe or unwrapping since
we know the modes are correct.
* Fix build on NetBSD
Notably:
1. A typo in `f_flag` vs `f_flags` - this was probably never tested
2. Some pointless name differences - `st_mtimensec` vs
`st_mtime_nsec`
3. The big one: This said that LC_GLOBAL_LOCALE() was -1 "everywhere".
Well, not on NetBSD.
* ifdef for macos
Instead of skipping for non-interactive shells, skip when stdin is not a tty.
This allows the cursor to be set for scripts that use the `read` command.
