This is allowed
time a=b echo 123
but -- due to an oversight in 3de95038b0 (Make "time" a job prefix,
2019-12-21) -- this is not allowed:
not time a=b echo 123
Instead, this one one works:
not a=b time echo 123
which is weird because without the "not" this would run "/bin/time".
It seems wrong that "not" is not like the others. Swap the order
for consistency.
Note that unlike "not", "time" currently needs to come before variable
assignments, so "a=b time true" is disallowed. This matches zsh. POSIX
shells call "/bin/time" here. Since it's ambiguous, erroring out seems
fine. It's weird that we're inconsistent with not here but I guess
"command not" is not expected to have subtly different behavior.

Commit 29dc30711 (Insert some completions with quotes instead of
backslashes, 2024-04-13) wrongly copmletes
$ cat ~/space
to
$ cat '~/path with spaces'
Today completions can be either replacing or appending. We never quote
(but backslash-escape) appending completions (unless they "append"
to an empty token). We always quote replacing completions. The
assumption in this part of the code is that replacing completions
can be quoted without changing meaning.
This assumption is wrong for tildes. For the backslash-escaping code
path, we take care of this edge case via a special DONT_ESCAPE_TILDES
flag. However that flag does not take effect when using quotes for
escaping. Fix that.
Unfortunately, e97a4fab7 (Escape : and = in file completions,
2024-04-19) introduced a (hopefully temporary) code clone in
escape_separators, which made added an extra step to debugging here.
This now allows:
- Same argument (`random 5 5`)
- Swapped ends (`random 10 2`)
- One possibility (`random 0 5 4`)
This makes it easier to use with numbers generated elsewhere instead
of hard-coded, so you don't need to check as much before running it.
Fixes#10879
These are another way to spell the same thing that doesn't match what
`bind` would print.
They're also not documented and tested thoroughly.
Since they are just small shortcuts and unreleased we can just remove
them.
Fixes#10845
Given "printf %18446744073709551616s", we parse the number only in
the printf crate, which tells us that we overflowed somwhere (but
not where exactly).
Render the command line buffer only until the last line we can fit
on the screen.
If the cursor pushes the viewport such that neither the prompt nor
the first line of the command line buffer are visible, then we are
"scrolled". In this case we need to make sure to erase any leftover
prompt, so add a hack to disable the "shared_prefix" optimization
that tries to minimize redraws.
Down-arrow scrolls down only when on the last line, and up-arrow always
scrolls up as much as possible. This is somewhat unconventional;
probably we should change the up-arrow behavior but I guess it's a
good idea to show the prompt whenever possible. In future we could
solve that in a different way: we could keep the prompt visible even
if we're scrolled. This would work well because at least the left
prompt lives in a different column from the command line buffer.
However this assumption breaks when the first line in the command
line buffer is soft-wrapped, so keep this approach for now.
Note that we're still broken when complete-and-search or history-pager
try to draw a pager on top of an overfull screen. Will try to fix
this later.
Closes#7296
Commit ba67d20b7 (Refresh TTY timestamps after nextd/prevd, 2024-10-13)
wasn't quite right because it also needs to fix it for arbitrary commands.
While at it, do this only when needed:
1. It seems to be only relevant for multiline prompts.
Note that we can wait until after evaluation to check if the prompt is
multiline, because repaint events go through the queue, see 5ba21cd29
(Send repaint requests through the input queue again, 2024-04-19).
2. When the binding doesn't execute any external command, we probably don't
need to fix up whatever the user printed. If they actually wanted to show
output and print another prompt, they should currently use "__fish_echo",
to properly support multiline prompts. Bindings should produce no other
output. What distinguishes external programs is that they can trigger this
issue even if they don't produce any output that remains visible in fish,
namely by using the terminal's alternate screen.
Would be nice if we could get rid of __fish_echo; I'm not yet sure how.
Fixes#10800
Completion on ": {*," used to work but nowadays our attempt to wildcard-expand
it fails with a syntax error and we do nothing. This behavior probably only
makes sense for the overflow case, so do that.
Commit a91bf6d88 (builtin.c: builtin_source now checks that its argument is
a file., 2005-12-16) fixed an infinite loop for commands like "source /"
where the argument is a directory.
It did so by erroring out early unless the filename argument is a regular file.
This is too restrictive; it disallows reading from special files like /dev/null
and fifos.
Today we get a sensible error without this check, so remove it.
This fixes a macOS-specific bug. See 390b40e02 (Fix regression not refreshing
TTY timestamps after external command from binding, 2024-05-29) and 8a7c3ceec
(Don't abandon line after writing control sequences, 2024-04-06).
Fixes#10779
OSC 133 was added to tmux 3.4.
Also fix the test on macOS where we do have 3.5a in CI; for some reason we
get copy_cursor_y=6 there. I didn't investigate yet but at least that's
not the same bug this test was made to fix.
For multi-line prompts, we start each leading line with a clr_eol. Immediately
before printing these prompt lines we emit the OSC 133 prompt start marker.
Some terminals such as tmux interpret make clr_eol delete such markers,
hence prompt navigation is broken.
Fix this by printing the marker only after clr_eol.
The scenario where this triggers is quite odd. I haven't looked into why
the problem doesn't exist if I remove the recursive repaint request.
See https://github.com/tmux/tmux/issues/4183Closes#10776
This should make the sort have a strict weak ordering, which rust
requires since 1.81 (or it will panic).
Note: This changes the order, but that's *fine* since the current
order is random weirdness anyway.
Fixes#10763
This gave a weird error when you did e.g. `math Foo / 6`:
"Missing Operator" and only the "F" marked.
Adding an operator here anywhere won't help, so calling this an
"Unknown function" is closer to the truth. We also get nicer markings
because we know the extent of the identifier.
__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.
