__fish_apropos is a huge hack under macOS and it seems that it's either broken
or man pages are missing/not indexed under CI. In all cases, hard-code the
results of __fish_describe_command to test the integration machinery
specifically and get the test to pass under macOS CI.
Add round options, but I think can also add floor, ceiling, etc. And
the default mode is trunc.

Due to the inherent floating point accuracy issues under i586 described
in #10474 and at https://github.com/rust-lang/rust/issues/114479, we need to add
a workaround to our littlecheck math tests to perform less stringent comparisons
when fish was built for x86 without SSE2 support.
This commit addresses the littlecheck issues that caused #10474 to be re-opened,
but I still have to reproduce the cargo test failures for
`negative_precision_width`, `test_float`, `test_float_g`, and `test_locale`.
We require 3.19
This also makes skipped tests visible, which showed that the
print-help test was never run because the REQUIRES line was off.
In sh-mode, bash's `command -v` returns true if *all* commands exist.
One issue with fish_add_path at the moment is that it is sometimes a bit too intransparent.
You'll try to add a path, but it won't appear - was that because it wasn't a directory,
or because it doesn't exist, or because it was already included?
If it isn't usable after, did fish_add_path not add it because of something or did something *else* remove it?
So we give more explanations - "skipping this because it's a file", "not setting anything because no paths are left to add", ...
This enabled the profile in fish_setlocale, which caused startup
profile to always be on, so
```fish
fish --profile file -c 'foo'
```
would show the entire startup as well
The C++ version of this code simply copied the entire uvar table.
Today we take a reference. It's not clear which one is better.
Removal of locale variables like LC_ALL triggers variable change handlers
which call EnvStackImpl::get. This deadlocks because we still hold the lock
to protect the reference to all uvars. Work around this.
Closes#10513
This allows running `set` without triggering any event handlers.
That is useful, for example, if you want to set a variable in an event
handler for that variable - we could do it, for example, in the
fish_user_path or fish_key_bindings handlers.
This is something the `block` builtin was supposed to be for, but it
never really worked because it only allows suppressing the event for
the duration, they would fire later. See #9030.
Because it is possible to abuse this, we only have a long-option so
that people see what is up.
Commit a583fe723 ("commandline -f foo" to skip queue and execute immediately,
2024-04-08) fixed the execution order of some bindings but was partially
backed out in 5ba21cd29 (Send repaint requests through the input queue again,
2024-04-19) because repainting outside toplevel yields surprising results
(wrong $status etc).
Transient prompts wants to first repaint and then execute some more readline
commands, all within a single binding. This was broken by the second commit
because that one defers the repaint until after the binding has finished.
Work around this problem by deferring input events again while a readline
event was queued. This is closest to the historical behavior.
The implementation feels hacky; we might find odd situations.
For example,
commandline -f repaint end-of-line
set token (commandline -t)
sets the wrong token.
Probably not a very important case. We could throw an error or make it work
by letting "commandline -t" drain the input queue.
That seems too complicated, better change repaints to not use the input queue
(and fake $status etc). Let's try to do that in future.
Closes#10492
Given "abbr foo something", the input sequence
foo<space><ctrl-z><space>
would re-expand the abbreviation on the second space which is surprising
because the cursor is not at or inside the command token. This looks to be
a regression from 00432df42 (Trigger abbreviations after inserting process
separators, 2024-04-13)
Happily, 69583f303 (Allow restricting abbreviations to specific commands
(#10452), 2024-04-24) made some changes that mean the bad commit seems no
longer necessary. Not sure why it works but I'll take it.
On a command with multiline quoted string like
begin
echo "line1
line2"
end
we actually indent line2 which seeems misleading because the indentation
changes the behavior when typed into a script.
This has become more prominent since commits
- a37629f86 (fish_clipboard_copy: indent multiline commands, 2024-04-13)
- 611a0572b (builtins type/functions: indent interactively-defined functions, 2024-04-12)
- 222673f33 (edit_command_buffer: send indented commandline to editor, 2024-04-12)
which add indentation to an exported commandline.
Never indent quoted strings, to make sure the rendering matches the semantics.
Note that we do need to indent the opening quote which is fine because
it's on the same line.
While at it, indent command substitutions recursively. That feature should
also be added to fish_indent's formatting mode (which is the default).
Fortunately the formatting mode already works fine with quoted strings;
it does not indent them. Not sure how that's done and whether indentation
can use the same logic.
vared.fish is installed at
/home/fishuser/fish-build/test/buildroot/usr/local/share/fish/functions/vared.fish
as oppposed to being sourced from share/functions/.
I'm not 100% sure why this happens but it doesn't seem wrong.
These take over two minutes under ASAN (like ~40 seconds without, so
they aren't quick to begin with), and don't really give any additional
insight.
So we skip them to save time
This tries to open the given file to use as stdin, and if it fails,
for any reason, it uses /dev/null instead.
This is useful in cases where we would otherwise do either of these:
```fish
test -r /path/to/file
and string match foo < /path/to/file
cat /path/to/file 2>/dev/null | string match foo
```
This both makes it nicer and shorter, *and* helps with TOCTTOU - what if the file is removed/changed after the check?
The reason for reading /dev/null instead of a closed fd is that a closed fd will often cause an error.
In case opening /dev/null fails, it still skips the command.
That's really a last resort for when the operating system
has turned out to be a platypus and not a unix.
Fixes#4865
(cherry picked from commit df8b9b7095)
This introduces a feature flag, "test-require-arg", that removes builtin test's zero and one argument special modes.
That means:
- `test -n` returns false
- `test -z` returns true
- `test -x` with any other option errors out with "missing argument"
- `test foo` errors out as expecting an option
`test -n` returning true is a frequent source of confusion, and so we are breaking with posix in this regard.
As always the flag defaults to off and can be turned on. In future it will default to on and then eventually be made read-only.
There is a new FLOG category "deprecated-test", run `fish -d deprecated-test` and it will show any test call that would change in future.
Another consequence of a583fe723 ("commandline -f foo" to skip queue
and execute immediately, 2024-04-08) is that "commandline -f repaint"
will paint the prompt with the current value of $status which might be
set from a shell command in a the currently executing binding, instead of
waiting for the top-level status. This is wrong, at least historically. It
surfaces in bindings like alt-w which always paint a status value of [1]
when on single-lines commandlines.
Another regression is that a redundant repaint in a signal handler outputs
an extra prompt.
Fix both by making repaint commands go over the input queue again. This way,
they are always run with a good commandline state. There is no need to
repaint immediately because I don't think anyone has a data dependency on it
(we currently don't expose the prompt string), it's only for rendering.
Popular operating systems support shift-delete to delete the selected item
in an autocompletion widgets. We already support this in the history pager.
Let's do the same for up-arrow history search.

File names that have lots of spaces look quite ugly when inserted as
completions because every space will have a backslash.
Add an initial heuristic to decide when to use quotes instead of
backslash escapes.
Quote when
1. it's not an autosuggestion
2. we replace the token or insert a fresh one
3. we will add a space at the end
In future we could relax some of these requirements.
Requirement 2 means we don't quote when appending to an existing token.
Need to find a natural behavior here.
Re 3, if the completion adds no space, users will probably want to add more
characters, which looks a bit weird if the token has a trailing quote.
We could relax this requirement for directory completions, so «ls so»
completes to «ls 'some dir with spaces'/».
Closes#5433
I think commit 8386088b3 (Update commandline state changes eagerly as well,
2024-04-11) broke the alt-s binding.
This is because we update the commandline state snapshot (which is consumed
by builtin commandline and others) only at key points. This seems like a
dubious optimization. With the new streamlined bind execution semantics,
this doesn't really work anymore; any shell command can run any number of
commands like "commandline -i foo" which should synchronize.
Do the simple thing of calculating the snapshot whenever needed.
