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 (!).
This isn't quite the old-style test, but it checks some of the line
continuation stuff.
Note that littlecheck ignores leading whitespace, so testing the
actual indentation requires some more effort.
Things like
```fish
\
echo foo
```
or
```fish
echo foo; \
echo bar
```
are a formatting blunder and should be handled.
This makes it so the escaped newline is removed, and the
semicolon/token_type_end handling will then put the statements on
different lines.
One case this doesn't handle brilliantly is an escaped newline after a
pipe:
```fish
echo foo | \
cat
```
is turned into
```fish
echo foo | cat
```
which here works great, but in long pipelines can cause issues.
Pipes at the end of the line cause fish to continue parsing on the
next line, so this can just be written as
```fish
echo foo |
cat
```
for now.
