For coreutils, there are two build artifacts:
1. multicall executable (each utility is a separate static library)
2. individual utilities (still separate library with main wrapper)
To avoid namespace collision, each utility crate is defined as
"uu_{CMD}". The end user only sees the original utility name. This
simplifies build.rs.
Also, the thin wrapper for the main() function is no longer contained in
the crate. It has been separated into a dedicated file. This was
necessary to work around Cargo's need for the crate name attribute to
match the name in the respective Cargo.toml.
Everything in src/common has been moved to src/uucore. This is defined
as a Cargo library, instead of directly included. This gives us
flexibility to make the library an external crate in the future.
Fixes#717.
Builds the uutils multicall binary containing all utils (except stdbuf)
by default. To only build a subset
`cargo --no-default-features --features <utils>`
can be used.
Whats missing is building the standalone binaries and a mechanism to
automatically disable the build of unix only utils on windows.
I switched over to the getopts crate on crates.io, instead of Rust's
private implementation. This will allow coreutils to build for Rust 1.0.
I'm splitting the updates into several commits for easier reviewing.
This is a reworked version of unexpand. I did this for two main
reasons:
1. The previous version of unexpand had issues correctly computing
tabstops when the `-a` flag was supplied.
2. The previous version assumed the input was UTF-8. This version works
with non-UTF-8 inputs.
3. This version has a new flag, -U, which forces unexpand to
treat input as 8-bit ASCII rather than interpreting it
as UTF-8. This might be handy in some cases.
