- Introduce BUILTIN_ERR_COMBO2_EXCLUSIVE
- Distill generally more terse, unambiguous error descriptions.
Remember English is not everyone's language.
- Do not capitalize sentence fragments
- Use the modality where problem input is in a %s: prefix, then
is explained.
- Do not address the user (the "You cannot do ..." kraderism)
- Spell out 'arguments' rather than 'args' for consistency
- Mention 'function' as a scope
Watching for exit events is rare, so check if we have any exit events
before actually emitting them. This saves about 2% of time in
external_cmds benchmark.
This untangles some of the complicated logic and loops around posting
job exit events, and invoking the fish_job_summary function. No
functional change here (hopefully).
Prior to this change, job_t::is_stopped() returned true if there were
zero running processes in the job. This meant that completed jobs were
reported as stopped. Stop doing this, it's a footgun.
Exited processes generate event_t::process_exit if they exit with a
nonzero status. Prior to this change, to avoid sending duplicate events,
we would clear the status. This is ugly since we're lying about the
process exit status. Use a real flag to prevent sending duplicate
notifications.
This basically disables syntax highlighting. That doesn't mean we use
absolutely no colors - the search match, suggestion, selection and the
pager have coloring, but only reverse or brblack.
The idea is that this disables anything that tells you about
the *syntax*, but it still tells you about the state of the
commandline. If we didn't highlight the selection it would be entirely
invisible, and if we didn't highlight the suggestion you would have no
idea where it begins.
So this basically brings colors on-par with bash, where the search
match is colored (in reverse) and suggestions aren't a thing.
An alternative is to add a $fish_highlighting_enabled variable like
the one for suggestions. That's still possible, but would require some
internal changes to avoid coloring some things with $fish_color_normal
and other things with the normal terminal color.
One thing this also does not do is set the git prompt colors. These
are currently disallowed from being set in theme files because they
start with `__fish` instead of just `fish`. We should probably rename
them.
This adds a variable, $fish_autosuggestion_enabled.
When set to 0, it will turn off autosuggestions/highlighting.
Setting it to anything else will enable it (which also
means this remains enabled by default).
The point here is to let issues be *done*, and have any *new*
discussions happen in *new* issues so you can decouple the context.
This revert pending further discussion.
This program uses the Cobra framework for argument parsing and completion generation.
Just source the completions supplied by upstream.
This works around "go install" not being able to install completions files (only binaries).
Commit ec3d3a481 (Support "$(cmd)" command substitution without line
splitting, 2021-07-02) started treating an input string like
"a$()b" as if it were "a"$()"b". Yet, we do not actually insert the
virtual quotes. Instead we just adapted the definition of when quotes
are closed - hence the changes to quote_end().
parse_util_locate_cmdsubst_range() is aware
of the changes to quote_end() but some of its
callers like parse_util_detect_errors_in_argument() and
highlighter_t::color_as_argument() are not. They split strings at
command substitution boundaries without handling the special quoting
rules. (Only the expansion logic did it right.)
Fix this by handling the special quoting rules inside
parse_util_locate_cmdsubst_range(). This is a bit hacky since it
makes it harder for callers to process some substrings in between
command substitutions, but that's okay because current callers only
care about what's inside the command substitutions.
Fixes#8394
For some reason on a current glibc 2.33, the configure check fails.
The man page says we'd have to define XOPEN_SOURCE>=700, but I don't
want to do that since it changes a bunch of other things, and it
didn't work in my tests.
So we just force it, since we know it works (since glibc 2.3).
This is a performance difference of ~20% for printf, so it's a
reasonably big deal.
Since #4376, for-loops would set the loop variable outside, so it
stays valid.
They did this by doing the equivalent of
```fish
set -l foo $foo
for foo in 1 2 3
```
And that first imaginary `set -l` would also fire a set-event.
Since there's no use for it and the variable isn't actually set, we
remove it.
Fixes#8384.
