This was always extremely weasel-wordy and I have no idea which one
here is a good choice.
OMF is basically inactive at this point, so we might be doing people a
disservice by linking to it.
This wasn't providing a lot of value, and the license compatibility is iffy.
There's a bit of weirdness in that this now uses a `Box<dyn Error>`,
but since currently nothing actually errors out let's punt that for
later.
This is a terrible way of going about things,
and means we're currently broken on any unix that isn't specifically listed.
But at least it'll build and allow us to keep the FreeBSD CI running.
Historically fish has used the functions `fish_wcstol`, `fish_wcstoi`, and
`fish_wcstoul` (and some long long variants) for most integer conversions.
These have semantics that are deliberately different from the libc
functions, such as consuming trailing whitespace, and disallowing `-` in
unsigned versions.
fish has started to drift away from these semantics; some divergence from
C++ has crept in.
Rename the existing `fish_wcs*` functions in Rust to remove the fish
prefix, to express that they attempt to mirror libc semantics; then
introduce `fish_` wrappers which are ported from C++. Also fix some
miscellaneous bugs which have crept in, such as missing range checks.
This also skips the 192 git- and 64 npm- pages that
1. have better completions already (for the most part)
2. don't have the same name as a command typically in $PATH
In doing so it reduces the runtime on my system from 9s to 7s. Granted
I have all of these, so that's the best case.
This implements the primary environment stack, and other environments such
as the null and snapshot environments, in Rust. These are used to implement
the push and pop from block scoped commands such as `for` and `begin`, and
also function calls.
owning_null_terminated_array is used for environment variables, where we need to
provide envp for child processes. This switches the implementation from C++ to
Rust.
We retain the C++ owning_null_terminated_array_t; it simply wraps the Rust
version now.
The `u64::from(buf.f_flag)` was needed in two places. The existing handled macOS
which always has a 32-bit statfs::f_flag, but statvfs::f_flag is an `unsigned
long` which means it needs to be coerced to 64-bits on 32-bit targets.
It completes identical to `fg` and `bg` w/ this change. I'm not aware of any
reason why it shouldn't, but feel free to enlighten me if I've missed something.
