This will enable us to query for the current system's hostname in both Unix and Windows environments. We could have pulled in the 'gethostname' crate for this, but: 1. I'm not a huge fan of micro-crates. 2. The 'gethostname' crate panics if an error occurs. (Which, to be fair, an error should never occur, but it seems plausible on borked systems? ripgrep runs in a lot of places, so I'd rather not take the chance of a panic bringing down ripgrep for an optional convenience feature.) 3. The 'gethostname' crate uses the 'windows-targets' crate from Microsoft. This is arguably the "right" thing to do, but ripgrep doesn't use them yet and they appear high-churn. So I just added a safe wrapper to do this to winapi-util[1] and then inlined the Unix version here. This brings in no extra dependencies and the routine is fallible so that callers can recover from potentially strange failures. [1]: https://github.com/BurntSushi/winapi-util/pull/14
grep-cli
A utility library that provides common routines desired in search oriented command line applications. This includes, but is not limited to, parsing hex escapes, detecting whether stdin is readable and more. To the extent possible, this crate strives for compatibility across Windows, macOS and Linux.

Documentation
NOTE: You probably don't want to use this crate directly. Instead, you
should prefer the facade defined in the
grep
crate.
Usage
Add this to your Cargo.toml:
[dependencies]
grep-cli = "0.1"
