Here are the differences to the C++ version in fish_tests:
1. we don't need to chdir to repo root, cargo test already does.
2. we don't need srandom because we already use deterministic RNGs for tests.
3. we don't yet call asan_before_exit(). Not yet sure how to hook into
"cargo test" before exit.
This will allow to use "cargo test" for unit tests that depend on our
curses.rs.
This means that Rust.cmake depends on ConfigureChecks, so move that one to
the front.
Today, debounce-style work items are only created from the main thread.
The work to compute the result is done in a background thread but the
completion callback is called on the main thread again.
The completion callbacks used by the reader capture a shared reference to
ReaderData, which includes a Parser. Neither of those types needs to be
sent across threads.
The debounce machinery moves the completion callback into a function object
that is moved to the background thread and back again. Because of this
there is a Send requirement on the completion callback.
Since we already synchronize on MAIN_THREAD_QUEUE, we don't need Send from
the function object. Lift the requirement.
This removes an awkward hack from ParseError::describe_with_prefix,
where it added errors for two error codes.
andor_in_pipeline was already there, so we just need bare_variable_assignment.
Some of the completions recently introduced called Blender itself to query some
arguments, and Blender sometimes prints messages to stderr. This output was not
filtered, resulting in the shell printing irrelevant messages during completion.
This would misname `\e\x7F` as "backspace":
bind -k backspace 'do something'
bind \e\x7F 'do something'
because it would check if there was any key *in there*.
This was probably meant for continuous mode, but it simply doesn't
work right. It's preferable to not give a key when one would work over
giving one when it's not correct.
This file uses the questionable "self.somemethod(self.somefield)" pattern.
We should either set the functions free or stop passing redundant parameters.
Not sure.
For now fix one of them to avoid a string clone.
This implements input and input_common FFI pieces in input_ffi.rs, and
simultaneously ports bind.rs. This was done as a single commit because
builtin_bind would have required a substantial amount of work to use the input
ffi.
This will support rewriting the input machinery in Rust.
Note that while there are a lot of keys here, in practice this is very fast -
taking on the order of microseconds to populate.
