`streams.out.push_back` for fd_streams_t writes to the
fd *immediately*. We might want to introduce a general buffering
strategy, but in this case writing it in one go is the simplest and
seems acceptable - we already have constrained the argument size, so
just pushing it out should work well enough.
See #7836
013a563ed0 made it so we only try to
adjust terminal modes if we are in the terminal pgroup, but that's not
enough.
Fish starts background jobs in events inside its own pgroup, so
function on-foo --on-event foo
fish -c 'sleep 3' &
end
would have the backgrounded fish try to fiddle with the terminal and
succeed.
Instead, only fiddle with the terminal if we're interactive (this
should probably be extended to other bits, but this is the particular
problematic part)
Fixes#7842.
Consider
$ complete -c foo -a 'aab aaB' -f
$ foo A<TAB>
since 28d67c8 we would insert the common prefix AND show the pager.
Due to case-insensitive comparison, "b/B" was considered to be part
of the prefix. Since the prefix is added to each pager item [1]
we get wrong results. Fix this by removing the insensitive comparison
between completions - I don't think it was of much use anyway.
Commandline tokens are still matched case-insensitively, this is
just about completions.
Test this by running interactive fish inside tmux (pexpect's terminal
emulation not have enough capabilities). Also add tests for recent
interactive regressions #7526 and #7738.
Closes#3978
[1]: b38a23a would solve this differently by giving every pager item
its own prefix, but was reverted since it needs more fixes.
This should cover most cases - the user didn't install the docs and is
trying to view the man page via __fish_print_help, so we don't have a
way to show anything.
But `help thing` will fall back to the online version of the docs,
which should work if there's an internet connection.
See #7824.
Prior to this commit "builtin -h" would silently fail when no
documentation is installed. This happens when running fish without
installing it, or when the docs are not installed.
See #7824
After a fish installation is upgraded to 3.2.0, active shells could
throw an error attempting to load Git completions. It's just a
transient error but also easily avoidable by using the old style.
See #7822
Creating a file called "xfoo" could break the highlight tests because
we'd suddenly get a color with valid_path set to true.
So what we do is simply compare foreground/background and forced
underline, but only check for path validity if we're expecting a valid
path.
If we're not expecting a valid path, we don't fail whether it is there
or not.
This means that we can't check for a non-valid path, but we don't
currently do that anyway and we can just burn that bridge when we get
to it.

Previously, this message told the user to "set $BROWSER and try again". However,
when I first saw this error, I didn't know how I can set `BROWSER` in fish. Moreover,
I often see this error in situations when no browser will work. For instance, I might be
using fish over ssh, and I might either not know whether that system has a text-mode
browser installed or not want to use it.
A further improvement would be to report this message if a browser fails to start.
This concerns the behavior when running an external command from a key
binding. The history is:
Prior to 5f16a299a7, fish would run these external commands in shell
modes. This meant that fish would pick up any tty changes from external
commands (see #2114).
After 5f16a299a7, fish would save and restore its shell modes around
these external commands. This introduced a regression where anything the
user typed while a bound external command was executing would be echoed,
because external command mode has ECHO set in c_lflag. (This can be
reproed easily with `bind -q 'sleep 1'` and then pressing q and typing).
So 5f16a299a7 was reverted in fd9355966.
This commit partially reverts fd9355966. It has it both ways: external
commands are launched with shell modes, but/and shell modes are restored
after the external command completes. This allows commands to muck with
the tty, as long as they can handle getting shell modes; but it does not
enable ECHO mode so it fixes the regression found in #7770.
Fixes#7770. Fixes#2114 (for the third time!)
This partially reverts commit fd9355966e.
Unfortunately this causes input coming in while bind functions are
running to show up on screen.
Since the cure is worse than the disease let's just stop doing it.
My guess is this needs to *only* be done while running an external
command.
Fixes#7770
Reintroduces #2114
Partially reverts 5f16a299a7
This is broken on OpenBSD because it apparently doesn't have a /proc
we can query, so it just gives "fish".
Since it's unnecessary in this context just skip it.
This actually *worked* in my tests which confuses me.
It really shouldn't, `apropos -foo` will complain about "-o" not being
a valid option.
It should be `apropos -- -foo`.
Now, of course there are awful apropos implementations, so let's see
if someone complains
When executing “make test -jX” (with X > 1) to build and run tests in a
build directory, there is a race condition between the
serial_test_low_level target and the test_prep target (a dependency of
serial_test_fishscript and serial_test_interactive).
As far as I can tell, these events happen in a serial build scenario
(“make test” with the “Unix Makefiles” CMake generator):
1. The fish_tests binary is built and executed.
2. The test_prep target (a dependency of serial_test_fishscript)
cleans up test directories.
3. Tests in test.fish are executed.
In a parallel build scenario, this often happens:
1. Build of the fish_tests binary is started.
2. The test_prep target cleans up test directories.
3. Build of the fish_tests binary is finished.
4. Execution of the fish_tests binary starts.
5. Execution of the fish_tests binary finishes.
6. Tests in test.fish are executed.
However, if building the fish_tests binary is fast enough but not
instant (e.g. when using ccache), this can happen:
1. Build of the fish_tests binary is started.
2. Build of the fish_tests binary is finished.
3. Execution of the fish_tests binary starts.
4. The test_prep target cleans up test directories.
5. fish_tests tests that depend on said test directories may,
depending on timing, fail because they are wiped by test_prep.
Fix this by making test_prep a dependency of serial_test_low_level so
that test_prep can’t interfere with fish_tests execution.
For reasons unclear to me, fish enables bold mode unconditionally if
the background is set.
However, this called a background "set" if it wasn't exactly the
"normal" color, whereas set_color --print-colors would set a color
of *none*.
We have three special non-color colors:
- "normal"
- "reset"
- "none"
All of these specify some form of absence of background color, so all
of them should be checked.
Fixes#7805
