The previous commit added transient commandlines when completing
commands with variable overrides. Transient commandlines require a
parser, but perform_one_completion_cd_test() asked for completions
without giving a parser, which is only okay when asking for
autosuggestions (like perform_one_autosuggestion_cd_test() does).
Let's pass a parser to fix the test.
Today, a command like "var=val status " has custom completions
because we skip over the var=val variable override when detecting
the command token.
However if the custom completions read the commandline state (via
"commandline -opc") they do see they variable override, which breaks
them, most likely. Try "a=b git ".
For completions of wrapped commands, we already set a transient
commandline. Do the same for commands with leading variable overrides;
then git completions for "a=b git " will think the commandline is
"git ".
This updates widecharwidth to
6d3d55b419db93934517cb568d1a3d95909b4c7b, which includes the same
Hangul Jamo check in a separate table.
This should slightly speed up most width calculation because we no
longer need to do it for most chars, including the overwhelmingly
common ascii ones.
Also the range is increased and should better match reality.
`read` allows specifying the initial command line text. This was
text got accidentally ignored starting in a32248277f. Fix this
regression and add a test.

Previously, when we got an unknown option with --ignore-unknown, we
would increment woptind but still try to read the same contents.
This means in e.g.
```
argparse -i h -- -ooo -h
```
The `-h` would also be skipped as an option, because after the first
`-o` getopt reads the other two `-o` and skips that many options.
This could be handled more extensively in wgetopt, but the simpler fix
is to just skip to the next argv entry once we have an unknown option
- there's nothing more we can do with it anyway!
Additionally, document this and clearly explain that we currently
don't transform the option.
Fixes#8637
The sole notifiers test recreated the uvar directory, so if it was
called while the universal test was running it would stop it from
completing correctly.
This happened reasonably often on Ubuntu with tsan on Github Actions.
Cygwin tests are failing because cygwin has a low limit of only 64 fds in
select(). Extend select_wrapper_t to also support using poll(), according to
a FISH_USE_POLL new define. All systems now use poll() except for Mac.
Rename select_wrapper_t to fd_readable_set_t since now it may not wrap
select().
This allows the deep-cmdsub.fish test to pass on Cygwin.
This affects the caret position. In an expression like
123 456
we previously reported:
123 456
^ missing operator
Now we do:
123 456
^ missing operator
We do it on the first space, which should be acceptable.
(no need for a changelog entry, we have already ignored #8511)
This unit test was passing 0 instead of a pointer to indicate the end of
a varargs; this might fail on 64 bit, and indeed did fail on Cygwin. This
fixes the Cygwin expand test.
Only show the shebang warning for .fish commands.
Use the phrase "interpreter directive" as the formal name for the
shebang.
Switch from windows to Windows for the operating system.
There is no undefined behavior in closing a moved pipe, since the
move constructor simply sets the fd to -1, which is ignored by close().
The move constructor of autoclose_fd_t is "fully specified" (like
unique_ptr).
It's good practice to eagerly close pipes which may be inherited by
child processes, since otherwise the writer may not get EPIPE correctly.
Closing the pipe explicitly makes it clear that the pipe does not stay
open across continue_job().
This reverts commit c014c23662.
"not not return 34" exits with 34, not 1. This behavior is pretty
surprising but benign. I think it's very unlikely that anyone relies
on the opposite behavior, because using two "not" decorators in one
job is weird, and code that compares not's raw exit code is rare.
The behavior doesn't match our docs, but it's not worth changing the
docs because that would confuse newcomers. Add a test to cement the
behavior and a comment to explain this is intentional.
I considered adding the comment at
parse_execution_context_t::populate_not_process where this behavior
is implemented but the field defintion seems even better, because I
expect programmers to read that first.
Closes#8377
When we execute something and it doesn't have a shebang, typically we
fall back on running it with /bin/sh. For .fish scripts, we still
refuse to do this (assuming that /bin/sh won't handle .fish scripts properly).
Only the error wasn't great. So we now explicitly mention when there's
a missing shebang, and point towards the shebang line otherwise.
Seems like size_t is unnecessarily large as well, as elsewhere
in the code we are clamping down to uint32_t / source_offset_t.
This makes tok_t more like 16 bytes. More cleanup seems desirable,
this is not very well hamrnoized across our code base.
Instead of 7a80ad74f, which adds ifdeffery, we simply drop the
variables we don't care about. This leaves two presumably
glibc-specific variables, but drops 5 variables like LC_MONETARY, so
it's overall a win.
This reverts commit 7a80ad74f4.
The builtin history delete call has some code that removes a leading and
trailing quote from its arguments. This code dates back to ec34f2527a,
when the builtin was introduced. It seems wrong and tests pass
without it. Let's bravely remove it.
Use the remaining_to_disclose count to determine if all completions
are shown (allows consistent behavior between short and long completion
lists).
Closes#8485
Commit e40eba358 (Treat text following quoted command substitution
as quoted) made parse_util_locate_cmdsubst_range() aware of quoted
command substitutions, by skipping surrounding text via quote_end().
However, it was not quite right. We fail to properly parse
two consecutive command substitutions in the same string,
because we don't maintain the quoting context across calls to
parse_util_locate_cmdsubst_range(). Let's track that bit in a
parameter. This allows us to get rid of the quote_end() hack.
Also apply this to the other place where we call
parse_util_locate_cmdsubst_range() in a loop (highlighting).
Fixes#8500
