This indents continuations after pipes and conjunctions if they contain
a newline.
Example:
cmd1 &&
cmd2
But it avoids the "double indent" if it indented unconditionally:
cmd1 | begin
cmd2
end
More work towards improving #7252
Prior to this change, when emitting gap text (comments, newlines, etc),
fish_indent would use the indentation of the text at the end of the gap.
But this has the wrong result for this case:
begin
command
# comment
end
as the comment would get the indent of the 'end'. Instead use the indent
computed for the gap text itself.
Addresses one case of #7252.
It's useless - `expect` has a timeout anyway, and it defaults to 5s,
so these 0.5s sleeps just mean it'll always take at least 0.5s.
Sometimes it is useful to let things settle before *sending* text, and
it would be nice to be able to set the timeout for each expect
separately, but just adding to the timeout isn't useful.
This one sometimes fails with a zombie detected, so I'm assuming it's
too fast for reaping to happen, so we add another 100ms sleep.
Yeah, this isn't great but...eh
This can be used to determine whether the previous command produced a real status, or just carried over the status from the command before it. Backgrounded commands and variable assignments will not increment status_generation, all other commands will.
This changes how fish attempts to protect itself from calling tcsetpgrp() too
aggressively. Recall that tcsetpgrp() will "force" itself, if SIGTTOU is
ignored (which it is in fish when job control is enabled).
Prior to this fix, we avoided SIGTTINs by only transferring the tty ownership
if fish was already the owner. This dated from a time before we had really
nailed down how pgroups should be assigned. Now we more deliberately assign a
job's pgroup so we don't need this conservative check.
However we still need logic to avoid transferring the tty if fish is not the
owner. The bad case is when job control is enabled while fish is running in the
background - here fish would transfer the tty and "steal" from the foreground
process.
So retain the checks of the current tty owner but migrate them to the point of
calling tcsetpgrp() itself.
Unfortunately this doesn't quite fix the issue with Pantheon
Terminal (#7913), as that somehow manages to re-set $VTE_VERSION by
the time littlecheck runs.
This switches fish_indent from parsing with parse_tree
to the new ast.
This is the most difficult transition because the new ast retains less
lexical information than the old parse tree. The strategy is:
1. Use parse_util_compute_indents to compute indenting for each token.
2. Compute the "gap text" between the text of significant tokens. This
contains whitespace, comments, etc.
3. "Fix up" the gap text while leaving the significant tokens alone.
I really kinda hate how insistent clang-format is to have line
breaks *IFF THE LINE IS TOO LONG*.
Like... lemme just add a break if it looks better, will you?
But it is the style at this time, so we shall tie an onion to our
belt.
A broken/missing optspec or `--` is a bug in the script using
argparse, an unknown option or invalid argument is a bug in using that script.
So in the former case print a stacktrace, because the person writing
the `argparse` call is at fault, in the latter don't.
Fixes#6703.
Note: This includes a super cheesy thing to print variable contents.
The expect version has one that's a bit more elaborate (featuring a
marker setup), but tbh that doesn't seem to be worth it.
If we do need it, we can add it, but it seems more likely we'd just do
`set -S`, or do it in a check instead.
With the new pexpect based framework, bind and pipeline expect tests can
be removed.
Amusingly the complete.fish check required the existence of bind.expect.
Fix the check at the same time.
Make it easier to use pexpect and to understand its error messages.
Switch to a style in tests using bound methods, which makes them
less noisy to write.
This adds a new interactive test framework based on Python's pexpect. This
is intended to supplant the TCL expect-based tests.
New tests go in `tests/pexpects/`. As a proof-of-concept, the
pipeline.expect test and the (gnarly) bind.expect test are ported to the
new framework.
There's a terrible number of fishscripts that start with
set path (dirname (status filename))
And that's really just a bit boring.
So let's let it be
set path (status dirname)
This is a function you can either execute once, interactively, or
stick in config.fish, and it will do the right thing.
Some options are included to choose some slightly different behavior,
like setting $PATH directly instead of $fish_user_paths, or moving
already existing components to the front/back instead of ignoring
them, or appending new components instead of prepending them.
The defaults were chosen because they are the most safe, and
especially because they allow it to be idempotent - running it again
and again and again won't change anything, it won't even run the
actual `set` because it skips that if all components are already in.
Fixes#6960.
Variables like $status and $history showed up in all scopes, including
universal, when querying with `set -q` or `set -S`.
This makes it so they all only count as set in global scope, because
we already only allow assignment to electric variables in global scope.
Fixes#7032
The default implementation will not print any output in that case, but this provides users with additional flexibility when it comes to customising the shell's behaviour.
This allows users to customise the behaviour of the shell by redefining the function. This is similar to how fish_title or fish_greeting behave, where the default implementation can be easily overridden.
The function receives as arguments the job id, command line, signal name and signal description.
Give string expansion an (optional) parent pgroup. This is threaded all
the way into eval(). This ensures that in a mixed pipeline like:
cmd | begin ; something (cmd2) ; end
that cmd2 and cmd have the same pgroup.
Add a test to ensure that command substitutions inherit pgroups
properly.
Fixes#6624
Changes it from
```
$fish_color_user: not set in local scope
$fish_color_user: set in global scope, unexported, with 1 elements
$fish_color_user[1]: length=3 value=|080|
$fish_color_user: set in universal scope, unexported, with 1 elements
$fish_color_user[1]: length=7 value=|brgreen|
```
(with the trailing empty line - not just a newline)
to
```
$fish_color_user: set in global scope, unexported, with 1 elements
$fish_color_user[1]: |080|
$fish_color_user: set in universal scope, unexported, with 1 elements
$fish_color_user[1]: |brgreen|
```
Prior to this fix, if job control is enabled but stdin is not a tty, we
would return an error from terminal_maybe_give_to_job which would cause us
to avoid waiting for the job. Instead just return notneeded.
Fixes#6573.
The description for an alias which already has escape sequences will
use backslash escapes for quoting; usually `string escape` can simply
quote it. Use a regex that accepts either escaping style.
Travis puts the commit message in an environment variable, so if it
contains the string `_flag` this would match TRAVIS_COMMIT_MESSAGE.
That happened in ca91c201c3, so the
tests failed.
We simply tighten the regex a little more, and make a commit message
that doesn't include the string.
This allows code of the form `if jobs -q $some_pid` in scripts to check whether a previously started job is still running. Previously this would return the correct value, but also print an error message.
The invalid argument errors will still be printed.
Added test cases for both.
Because `command ./somedir/somecommand` is okay.
Fixes test failure from aa304cbd3d.
Child directories in $PATH are still not suggested, as was the main
intention of the commit that introduced the tests:
8a3cf144f Don't include child directories of $PATH in completions.
We have now entirely switched the script tests to littlecheck.
Note: This adjusts the complete_directories test, because it removes a
directory that was created before by a .in test. There's no real
change in behavior.
This does require the test directory be cleaned, or the tests will fail.
test_util gets to stay for a while longer, because it sets up the
testing env (locale and such).
This, together with the other testX, really just tests some basic
syntax. So let's just call it "basic".
Note that this file uses escaped newlines on purpose, so restyling it
would currently break it. I'm not sure what the best thing to do here is.
Instead of invoking littlecheck.py independently for each file, pass
all files at once. This amortizes the Python startup cost, and reduces
the total test time by ~15 seconds (!).
