fish reads the tty modes at startup, and tries to restore them to the
original values on exit, to be polite. However this causes problems when
fish is run in a pipeline with another process which also messes with the
tty modes. Example:
fish -c 'echo foo' | vim -
Here vim's manipulation of the tty would race with fish, and often vim
would end up with broken modes.
Only restore the tty if we are interactive. Fixes#8705.
This is a big cleanup to how tty transfer works. Recall that when job
control is active, we transfer the tty to jobs via tcsetpgrp().
Previously, transferring was done "as needed" in continue_job. That is, if
we are running a job, and the job wants the terminal and does not have it,
we will transfer the tty at that point.
This got pretty weird when running mixed pipelines. For example:
cmd1 | func1 | cmd2
Here we would run `func1` before calling continue_job. Thus the tty
would be transferred by the nested function invocation, and also restored
by that invocation, potentially racing with tty manipulation from cmd1 or
cmd2.
In the new model, migrate the tty transfer responsibility outside of
continue_job. The caller of continue_job is then responsible for setting up
the tty. There's two places where this gets done:
1. In `exec_job`, where we run a job for the first time.
2. In `builtin_fg` where we continue a stopped job in the foreground.
Fixes#8699
* Implement fish_wcstod_underscores
* Add fish_wcstod_underscores unit tests
* Switch to using fish_wcstod_underscores in tinyexpr
* Add tests for math builtin underscore separator functionality
* Add documentation for underscore separators for math builtin
* Add a changelog entry for underscore numeric separators
Helm 3 provides an autogenerated completion since version 3.4.0.
The previous implementation is replaced by this because it was specific to the
now-deprecated helm 2.
The completions appear to be fully featured including descriptions and
completion for dynamic arguments such as namespaces and releases.
Their names are not perfect, so let's keep them as internal functions,
until we figure out how/if we want to expose this.
This reverts 0445126c2 (Undunder __fish_is_nth_token, 2021-06-29) (but I
did it without "git revert").
Closes#8008
If you have vim set up to recognize `.editorconfig` files, the 80-char limit
from ours causes vim to keep chopping lines. This makes it ignore that limit
when editing `CHANGELOG.rst`
Say the user has a multi-char binding (typically an escape sequence), and a
signal arrives partway through the binding. The signal has an event handler
which enques some readline event, for example, `repaint`. Prior to this
change, the readline event would cause the multi-char binding to fail. This
would cause bits of the escape sequence to be printed to the screen.
Fix this by noticing when a sequence was "interrupted" by a non-char event,
and then rotating a sequence of such interruptions to the front of the
queue.
Fixes#8628
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 ".
