In brief: - Lines no longer end with trailing whitespace. - fixed length calculation when tabs are present - word splitting gives more info to the line breaking process, which should be useful for K-P - code cleanup here and there - K-P is not implemented yet. That's next. There is some dead code in linebreak.rs that forms the basis for K-P. - Performance has regressed somewhat; we're now about 60% slower than GNU fmt (formerly about 20%), but we are basically on par with OpenBSD fmt. - addressed comments from Arcterus on PR This is a squash of the following local commits: 1feceb0 - address comments from Arcterus on PR b36aa90 - use word_nchars rather than w.len() for first word f44a629 - proper tab handling 4f57593 - added tab analysis info to WordInfo 211f4a5 - pass WordInfo by ref 80e14b9 - overhaul word splitting apparatus d29f2e6 - tidy up the breaking by passing arg struct pointer d8020df - lines blank save for prefix act as par separators 8bd7f1e - fixed tab behavior in -u a2387f7 - cleaner prefix handling ; cleanup ; prep for K-P
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'
To build the multicall binary (i.e. BusyBox-like binary):
make MULTICALL=1
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 the multicall binary:
make MULTICALL=1 install
To install every program (other than the multicall binary) with a prefix:
make PROG_PREFIX=PREFIX_GOES_HERE install
Uninstallation Instructions
To uninstall all utilities:
make uninstall
To uninstall the multicall binary:
make MULTICALL=1 uninstall
To uninstall every program (other than the multicall binary) 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.
- Submit a pull request and close the issue. Your pull request should include deleting the utility from the to-do list on this README.
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.
