Add completions for trash-cli commands:
trash, trash-empty, trash-list, trash-put and trash-restore.
``trash --help`` are used to identify the executable in trash cli completion.
(cherry picked from commit ce268b74dd)
Separate the neovim completions from the vim ones, as their supported
options have diverged considerably.
Some documented options are not yet implemented, these are added but
commented out.
Closes#9535.

When we draw the prompt, we move the cursor to the actual
position *we* think it is by issuing a carriage return (via
`move(0,0)`), and then going forward until we hit the spot.
This helps when the terminal and fish disagree on the width of the
prompt, because we are now definitely in the correct place, so we can
only overwrite a bit of the prompt (if it renders longer than we
expected) or leave space after the prompt. Both of these are benign in
comparison to staircase effects we would otherwise get.
Unfortunately, midnight commander ("mc") tries to extract the last
line of the prompt, and does so in a way that is overly naive - it
resets everything to 0 when it sees a `\r`, and doesn't account for
cursor movement. In effect it's playing a terminal, but not committing
to the bit.
Since this has been an open request in mc for quite a while, we hack
around it, by checking the $MC_SID environment variable.
If we see it, we skip the clearing. We end up most likely doing
relative movement from where we think we are, and in most cases it
should be *fine*.

Rewrite completions for meson to expose meson commands with their
options and subcommands. New completions are based on the meson 1.0.
Subcommands were introduced in meson 0.42.0 (August 2017), so new
completions will only work for versions after 0.42.0. At this moment,
even oldstable Debian (buster) has meson 0.49.2 -- which means it is
unlikely someone will be affected.

* wutil: Rewrite `wrealpath` in Rust
* Reduce use of FFI types in `wrealpath`
* Addressed PR comments regarding allocation
* Replace let binding assignment with regular comparison
More ugliness with types that cxx bridge can't recognize as being POD. Using
pointers to get/set `termios` values with an assert to make sure we're using
identical definitions on both sides (in cpp from the system headers and in rust
from the libc crate as exported).
I don't know why cxx bridge doesn't allow `SharedPtr<OpaqueRustType>` but we can
work around it in C++ by converting a `Box<T>` to a `shared_ptr<T>` then convert
it back when it needs to be destructed. I can't find a clean way of doing it
from the cxx bridge wrapper so for now it needs to be done manually in the C++
code.
Types/values that are drop-in ready over ffi are renamed to match the old cpp
names but for types that now differ due to ffi difficulties I've left the `_ffi`
in the function names to indicate that this isn't the "correct" way of using the
types/methods.
We want to keep the cast because tv_sec is not always 64 bits, see b5ff175b4
(Fix timer.rs cross-platform compilation, 2023-02-14).
It would be nice to avoid the clippy exemption, perhaps using something like
#[cfg(target_pointer_width = "32")]
let seconds = val.tv_sec as i64;
#[cfg(not(target_pointer_width = "32"))]
let seconds = val.tv_sec;
but I'm not sure if "target_pointer_width" is the right criteria.
The FISH_RUST_TARGET_DIR is not set for Tests.cmake, the target_dir will set to
$CARGO_MANIFEST_DIR/target. But if build.target-dir or CARGO_TARGET_DIR is set,
the real target_dir doesn't at the $CARGO_MANIFEST_DIR/target. It causes failure
in cargo test. Then, set --target-dir for cargo test.

This removes a weird `ls` call (that just decorates directories), and
makes it behave like normal path completion.
(really, this should be a proper option to complete)
Fixes#9285
(cherry picked from commit 4a8ebc0744)
Upsizing to `usize` from `i32` doesn't work if `usize` is only 32-bits.
I changed the code to use the `FromStr` impl on `i32`, but we could have also
just used `u64` instead of `i32`.
Also, we should get in the habit of using the appropriate type aliases where
possible (`i32` should be `RawFd`).
We want to try and catch as much unexpected/non-deterministic behavior as we
can. We could run the CI explicitly in debug mode, but I think it makes sense to
always have overflow checks on in both debug/release modes everywhere, at least
for the duration of the codebase transition.
The mutex was being locked from the very start, before it was needed and
possibly before it would be needed.
Also rename the static global to stick to rust naming conventions.
Note that `once_cell::sync::Lazy<T>` actually internally uses its own lock
around the value, but in this case it's insufficient because `SmallRng` doesn't
implement `SeedableRng` so we can't reseed it with only an `&mut` reference and
must instead replace its value.
We probably *could* still use `Lazy<SmallRng>` directly and then rely on
`std::mem::swap()` to replace the contents of the shared global static without
reassigning the variable directly with a new `SmallRng` instance, but I'm not
sure that's a great idea. This is just a built-in, there's no real harm in
locking twice (especially while fish remains essentially single-threaded).
The old comments about using i128 logic were still there even though we are no
longer using that approach and the output type was very much misleadingly a u64
printed to the console (but via `%d` so it was ultimately shown as an i64). Be
explicit about the resulting being a valid i64 value before passing it to the
sprintf!() macro.
Also add comments about the safety of the final `unwrap()` operation.
Rust doesn't have __FUNCTION__ or __func__ (though you can hack around it with a
proc macro, but that will require a separate crate and slowing down compilation
times with heavy proc macro dependencies), so these are just regular functions
(at least for now). Rust's default stack trace on panic (even in release mode)
should be enough (and the functions themselves are inlined so the calling
function should be the second frame from the top, after the #[cold] panic
functions).
This is to allow us to verify some implementation details that aren't explicitly
documented in the rust standard library's documentation.
std::thread uses `pthread_create()` underneath the hood on *nix platforms, so
this *should* merely be a formality.
The way cxx bridge works, it doesn't recognize any types from another module as
being shared cxx bridge types with generations native to both C++ and Rust,
meaning every module that was going to use function pointers would have to
define its own `c_void` type (because cxx bridge doesn't recognize any of
libc::c_void, std::ffi::c_void, or autocxx::c_void).
FFI on other platforms has long used the equivalent of `uint8_t *` as an
alternative to `void *` for code where `void` was not available or was
undesirable for some reason. We can join the club - this way we can always use
`* {const|mut} u8` in our rust code and `uint8_t *` in our C++ code to pass
around parameters or values over the C abi.
I needed to rename some types already ported to rust so they don't clash with
their still-extant cpp counterparts. Helper ffi functions added to avoid needing
to dynamically allocate an FdMonitorItem for every fd (we use dozens per basic
prompt).
I ported some functions from cpp to rust that are used only in the backend but
without removing their existing cpp counterparts so cpp code can continue to use
their version of them (`wperror` and `make_detached_pthread`).
I ran into issues porting line-by-line logic because rust inverts the behavior
of `std::remove_if(..)` by making it (basically) `Vec::retain_if(..)` so I
replaced bools with an explict enum to make everything clearer.
I'll port the cpp tests for this separately, for now they're using ffi.
Porting closures was ugly. It's nothing hard, but it's very ugly as now each
capturing lambda has been changed into an explicit struct that contains its
parameters (that needs to be dynamically allocated), a standalone callback
(member) function to replace the lambda contents, and a separate trampoline
function to call it from rust over the shared C abi (not really relevant to
x86_64 w/ its single calling convention but probably needed on other platforms).
I don't like that `fd_monitor.rs` has its own `c_void`. I couldn't find a way to
move that to `ffi.rs` but still get cxx bridge to consider it a shared POD.
Every time I moved it to a different module, it would consider it to be an
opaque rust type instead. I worry this means we're going to have multiple
`c_void1`, `c_void2`, etc. types as we continue to port code to use function
pointers.
Also, rust treats raw pointers as foreign so you can't do `impl Send for * const
Foo` even if `Foo` is from the same module. That necessitated a wrapper type
(`void_ptr`) that implements `Send` and `Sync` so we can move stuff between
threads.
The code in fd_monitor_t has been split into two objects, one that is used by
the caller and a separate one associated with the background thread (this is
made nice and clean by rust's ownership model). Objects not needed under the
lock (i.e. accessed by the background thread exclusively) were moved to the
separate `BackgroundFdMonitor` type.
