Just as `math "bitand(5,3)"` and `math "bitor(6,2)"`.
These cast to long long before doing their thing,
so they truncate to an integer, producing weird results with floats.
That's to be expected because float representation is *very*
different, and performing bitwise operations on floats feels quite useless.
Fixes#7281.
It could be nice to use a heuristic for this in future, but for now let's
stick to the old behavior so we can keep formatting scripts without occasional
bad formatting changes.
A heuristic could also be used to break lines after |, && or || but I don't
think there is much need for that at the moment.
Closes#7252
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.
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 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.
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.
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.
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.
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
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.
