This was previously limited to Linux predicated on the existence
of certain headers, but Rust just exposes those functions unconditionally. So
remove the check and just perform the mtime hack on Linux and Android.
Make sure to also look for the error part that occurs after the last format
specifier.
Still not great because it won't fail if there's unexpected output at the
beginning or end of the string.
Commit 5f849d0 changed control-C to print an inverted ^C and then a newline.
The original motivation was

This sounds like a valid use case in some scenarios but I think that most
abandoned commands are noise. After all, the user erased them. Also, now that
we have undo that can be used to get back a limited set of canceled commands.
I believe the original motivation for existing behavior (in other shells) was
that TERM=dumb does not support erasing characters. Similarly, other shells
like to leave behind other artifacts, for example when using tab-completion
or in their interactive menus but we generally don't.
Control-C is the obvious way to quickly clear a multi-line commandline.
IPython does the same. For the other behavior we have Alt-# although that's
probably not very well-known.
Restore the old Control-C behavior of simply clearing the command line.
Our unused __fish_cancel_commandline still prints the ^C. For folks who
have explicitly bound ^C to that, it's probably better to keep the existing
behavior, so let's leave this one.
Previous attempt at #4713 fizzled.

This function is a hotspot, but it has inefficient codegen:
1. For whatever reason, the chars() iterator of wstr is slower
than that of a slice. Use the slice.
2. Unnecessary overflow checks were preventing vectorization.
Switch to a more optimized implementation.
This improves aliases benchmark time by about 9%.
Since none of the compiles(xxx) calls are to particularly complex code, we can
just use `rsconf` directly to test for the presence of the symbols or headers as
needed.
Note that it seems at least some of the previous detection was not working
correctly; in particular HAVE_PIPE2 was evaluating to false on my WSL install
where pipe2(2) was available (caught because it revealed some compilation errors
in that conditional compilation path after porting).
I kept the cfg names and the tests themselves mostly as-is, though we might want
to change that to conform with the rust convention of lowercase cfg names and
decide whether we want to prefix all these with have_, fish_, or nothing at all.
Also the posix_spawn() test should probably check for the symbol `posix_spawn()`
rather than the header `spawn.h` since we don't use it via the header but rather
via the symbol (but in reality they're almost certainly going to give the same
result).
NB: I only encountered this when rewriting the cfg detection, which means that
the previous detection wasn't correct since I have pipe2 on Linux but didn't run
into this build error before.
I had originally created a safe `set_locale()` wrapper and clippy-disallowed
`libc::setlocale()` but almost all our uses of `libc::setlocale()` are in a loop
where it makes much more sense to just obtain the lock outright then call
`setlocale()` repeatedly rather than lock it in the wrapper function each time.
No need to use cfg_attr and have to worry about syncing the preconditions for
the cfg_attr with the preconditions for where `slice_contains_slice()` is used
in the codebase, just mark it as `allow(unused)` with a comment.
Use Rust for executables
Drops the C++ entry points and restructures the Rust package into a
library and three binary crates.
Renames the fish-rust package to fish.
At least on Ubuntu, "fish_indent" is built before "fish".
Make sure export CURSES_LIBRARY_LIST to all binaries to make sure
that "cached-curses-libnames" is populated.
Closes#10198
Keep running tests serially to avoid breaking assumptions.
I think many of these tests can run in parallel and/or don't need test_init().
Use the safe variant everywhere, to get it done faster.
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 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.
The existing subsequence search commonly returns false positives.
Support globs, to allow searching for disconnected substrings in a better way.
