fmt:
- Implemented Knuth-Plass optimal linebreaking strategy.
- Added commandline switch -q for "quick" (greedy) split
mode that does not use Knuth-Plass.
- Right now, Knuth-Plass runs about half as fast. It also
uses more memory.
- Updated fmt to use char_width (see below) instead of
assuming each character width is 1.
- Use i64 for demerits instead of int in K-P, since int is
pointer sized and will only be 32 bits on some
architectures.
- incremented version number
- Incorporated improvements suggested by huonw and Arcterus.
- K-P uses indices of linebreaks vector instead of raw
pointers. This gets rid of a lot of allocation of boxes
and improves safety to boot.
- Added a support module for computing displayed widths of unicode
strings based on Markus Kuhn's free implementation at
http://www.cl.cam.ac.uk/~mgk25/ucs/wcwidth.c
- This is in `charwidth.rs`, but this is a temporary measure
until the Char trait implements .width(). I am submitting
a PR for this soon, and the code in charwidth() is what's
generated libcore.

uutils coreutils 
uutils is an attempt at writing universal (as in cross-platform) CLI utils in Rust. This repo is to aggregate the GNU coreutils rewrites.
Why?
Many GNU, Linux and other utils are pretty awesome, and obviously some effort has been spent in the past to port them to Windows. However, those projects are either old, abandoned, hosted on CVS, written in platform-specific C, etc.
Rust provides a good, platform-agnostic way of writing systems utils that are easy to compile anywhere, and this is as good a way as any to try and learn it.
Build Instructions
To simply build all available utilities:
make
To build all but a few of the available utilities:
make DONT_BUILD='UTILITY_1 UTILITY_2'
To build only a few of the available utilities:
make BUILD='UTILITY_1 UTILITY_2'
Installation Instructions
To install all available utilities:
make install
To install all but a few of the available utilities:
make DONT_INSTALL='UTILITY_1 UTILITY_2' install
To install only a few of the available utilities:
make INSTALL='UTILITY_1 UTILITY_2' install
To install every program with a prefix:
make PROG_PREFIX=PREFIX_GOES_HERE install
Uninstallation Instructions
To uninstall all utilities:
make uninstall
To uninstall every program with a set prefix:
make PROG_PREFIX=PREFIX_GOES_HERE uninstall
Test Instructions
To simply test all available utilities:
make test
To test all but a few of the available utilities:
make DONT_TEST='UTILITY_1 UTILITY_2' test
To test only a few of the available utilities:
make TEST='UTILITY_1 UTILITY_2' test
Contribute
Contributions are very welcome, and should target Rust's master branch until Rust 1.0 is released. You may claim an item on the to-do list by following these steps:
- Open an issue named "Implement [the utility of your choice]", e.g. "Implement ls"
- State that you are working on this utility.
- Develop the utility.
- Add the reference to your utility into uutils/uutils.rs (required for multibinary).
- Remove utility from the to-do list on this README.
- Submit a pull request and close the issue.
The steps above imply that, before starting to work on a utility, you should search the issues to make sure no one else is working on it.
