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.
Closes#10890
This was added accidentally in 971d257e67 (Port AST to Rust,
2023-04-02). It does not seem to be causing an observable effect
(although I didn't try hard).
It's pretty annoying that this panics without sphinx, because the
install itself would be *working*.
So instead we tell the user that they need to clean or set
$FISH_BUILD_DOCS if they want to try again.
We get "undefined reference to `__memmove_chk'" when compiling
pcre2 (via pcre2-sys) on newer Ubuntu.
That one is used with higher fortify_source levels, and Ubuntu 24.04
defaults to 3, while my arch system (where I cannot reproduce)
defaults to 2.
The values we would try are:
xterm-256color, xterm, ansi, dumb
This is a pretty useless list, because systems without
"xterm-256color" but with "ansi" basically don't exist,
and it is very likely that the actual terminal is more
xterm-compatible than it is ansi.
So instead we just use our xterm-256color definition, which has a high
likelihood of being basically correct.
This is fairly subtle.
When installable, and we either can't find the version file or it is
outdated, we ask the user to confirm installation (just like `--install`).
We do that only if we are really truly interactive (with a tty!) to
avoid `fish -c` running into problems.
This check could be tightened even more, because currently:
```fish
fish -ic 'echo foo'
```
asks, while
```fish
fish -ic 'echo foo' < /dev/null
```
does not.
`fish -c` will still error out if it can't find the config, but it
will just run if it is out of date.
Unfortunately it does not appear like #[cfg(test)] works for build.rs?
Investigating a better solution, but this is a good idea anyway (or `make
test` would generate man pages via build.rs!)
This is unfortunately necessary, because otherwise it would not rerun
the build script just because you installed sphinx.
Because we use the man pages for --help output, they're pretty
necessary.
To override it, you can set $FISH_BUILD_DOCS=0, like
```fish
FISH_BUILD_DOCS=0 cargo install --path .
```
fish will print messages for some jobs when they exit abnormally, such as
with SIGABRT. If a job exits abnormally inside the prompt, then (prior to
this commit) fish would print the message and re-trigger the prompt, which
could result in an infinite loop. This has existed for a very long time.
Fix it by reaping jobs after running the prompt, and NOT triggering a
redraw based on that reaping. We still print the message but the prompt is
not executed.
Add a test.
Fixes#9796
This built on my test system, might be version differences.
(it's also not enough to make it *work*, but a necessary step)
This reverts commit 6fded249cd.
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.
