This increases a 100ms timeout to 200ms, because we've hit it on
Github Actions:
```
INPUT 3904.65 ms (Line 223): set -g fish_escape_delay_ms 100\n
OUTPUT +1.74 ms (Line 224): \rprompt 25>
INPUT +0.71 ms (Line 230): echo abc def
INPUT +0.57 ms (Line 231): \x1b
INPUT +0.57 ms (Line 232): t\r
OUTPUT +2.41 ms (Line 234): \r\ndef abc\r\n
OUTPUT +1.63 ms (Line 234): \rprompt 26>
INPUT +0.75 ms (Line 239): echo ghi jkl
INPUT +0.57 ms (Line 240): \x1b
INPUT +134.98 ms (Line 242): t\r
```
In other places it decreases sleeps where we just wait for a timeout to elapse, in which case we don't need much longer than the timeout.
And again clang-format does something I don't like:
- if (found != end && std::strncmp(found->name, name, len) == 0 && found->name[len] == 0) return found;
+ if (found != end && std::strncmp(found->name, name, len) == 0 && found->name[len] == 0)
+ return found;
I *know* this is a bit of a long line. I would still quite like having
no brace-less multi-line if *ever*. Either put the body on the same
line, or add braces.

E.g. if we do `string match -q`, and we find a match, nothing about
the input can change anything, so we quit early.
This is mainly useful for performance, but it also allows `string`
with `-q` to be used with infinite input (e.g. `yes`).
Alternative to #7495.
Currently a bit limited, unfortunately printf's `%a` specifier is
absolutely unreadable.
So we add `hex` and `octal` with `0x` and `0` prefixes respectively,
and also take a number but currently only allow 16 and 8.
The output is truncated to integer, so scale values other than 0 are
invalid and 0 is implied.
The docs mention this may change.
The '--import' flag was used for importing named capture groups, but it
was decided to always import them unconditionally. This flag was causing
the tests to fail.
Prior to this fix, when key binding is a script command (i.e. not a
readline command), fish would run that key binding using fish's shell
tty modes. Switch to using the external tty modes. This re-fixes
issue #2214.
With the upcoming fix to place the tty in external-proc mode, add a sleep
which resolves a race between emitting a newline and restoring it to shell
mode.
Prior to this change, when a process resumes because it is brought back
to the foreground, we would reset the terminal attributes to shell mode.
This fixed#2114 but subtly introduced #7483.
This backs out 9fd9f70346, re-introducing #2114 and re-fixing #7483.
A followup fix will re-fix #2114; these are broken out separately for
bisecting purposes.
Fixes#7483.
I *think* this might sometimes (on CI) be eating the prompt, so that the actual `prompt`
part of `expect_prompt` doesn't find anything.
On Github Actions we see things like:
```
Testing file pexpects/generic.py ... Failed to match pattern: prompt 5
generic.py:35: timeout from expect_prompt("echo .history.*")
[...]
OUTPUT +1.08 ms (Line 31): \rprompt 4>
INPUT +0.35 ms (Line 34): echo $history[1]\n
OUTPUT +1.58 ms (Line 35): echo $history[1]\r\necho $history[1]\r\n⏎ \r⏎ \r\rprompt 5>
```
so the prompt *is* printed, it's just not correctly matched.
Apparently on macOS SIGTSTP (from control-Z) causes `read()` to return
EINTR.
This means `cat | cat` will exit as soon as it's backgrounded and
brought back.
So instead we use `sleep`, which won't read(), and therefore is
impervious to these puny attacks.
See discussion in #7447.
The classic mistake: Some of these have a bit of a delay, but it's supposed to
be *under* the timeout, so it needs to be *shorter* not longer to
increase the slack.
We just had the following output on Github Actions:
INPUT +0.94 ms (Line 34): echo ghi jkl
INPUT +0.72 ms (Line 35): \x1b
INPUT +63.12 ms (Line 37): t\r
The default escape delay is 30ms, that had 60ms between an escape and
a tab, so it missed it.
So: We have to increase the delay for CI's benefit. Let's try with
80ms, because otherwise we'd have to bump up other timeouts and the
bind tests take long enough as it is.
Github Action's macOS builds are even more resource-starved (even tho
they use the same provider?) than
Travis, but Travis is unusable to us now, so....
In some cases the completion we come up with may be unexpected, e.g.
if you have files like
/etc/realfile
and
/etc/wrongfile
and enter "/etc/gile", it will accept "wrongfile" because "g" and
"ile" are in there - it's a substring insertion match.
The underlying cause was a typo, so it should be easy to go back.
So we do a bit of magic and let "cancel" undo, but only right after a
completion was accepted via complete or complete-and-search.
That means that just reflexively pressing escape would, by default, get you back to
the old token and let you fix your mistake.
We don't do this when the completion was accepted via the pager,
because 1. there's more of a chance to see the problem there and 2.
it's harder to redo in that case.
Fixes#7433.
This was typically overridden by "too many/few arguments", but it's
actually incorrect:
sin(55
has the correct number of arguments to `sin`, but it's lacking
the closing `)`.
We've heard news of this regressing, so let's add the test that should
have been there already (mea culpa!).
Because we now use POSIX_VDISABLE, this should also work in tandem
with ctrl-space (which sends NUL), but we can't test *that* because
some systems might not have POSIX_VDISABLE.
This switch is no longer necessary when only one command is given.
Internally completions are stored separately for each command,
so we only every print one command name per "complete" line anyway.
These aliases seem to be common, see #7389 and others. This prevents
recursion on that example, so `alias ssh "env TERM=screen ssh"` will just
have the same completions as ssh.
Checking the last token is a heuristic which hopefully works for most
cases. Users are encouraged to use functions instead of aliases.
Ensure that the increment= param is set via keyword, not via positional arg.
This mistake was masking a bug where the "^a b c" match was not being tested,
because it was being set as the value for increment!
This switches the 'increment' param from "after" to "before." Instead
of expect_prompt saying if the next prompt will be incremented, each
call site says if it should have been incremented sinec the last prompt.
I am not sure why this worked, actually.
These tests did not have $fish set anywhere, and on my fresh OpenBSD
VM it ended up calling whatever that calls "fish" (I think it's that
"Go fish!" game?).
