uutils is an attempt at writing universal (as in cross-platform) CLI
utils in [Rust](http://www.rust-lang.org). This repo is to aggregate the GNU
coreutils rewrites.
Why?
----
Many GNU, Linux and other utils are pretty awesome, and obviously
[some](http://gnuwin32.sourceforge.net) [effort](http://unxutils.sourceforge.net)
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.
Rust Version
------------
uutils follows Rust's release channels and is tested against stable, beta and nightly.
The current oldest supported version of the Rust compiler is `1.22.0`, but `1.20.0` is
known to work as well (test failures when compiling with `1.20.0` are due to the tests
themselves being broken by a change in the compiler).
On both Windows and Redox, only the nightly version is tested currently.
Build Instructions
------------------
To simply build all available utilities:
```
make
```
(on Windows use [MinGW/MSYS](http://www.mingw.org/wiki/MSYS) or `Cygwin` make and make sure you have `rustc` in `PATH`)
To build all but a few of the available utilities:
```
make SKIP_UTILS='UTILITY_1 UTILITY_2'
```
To build only a few of the available utilities:
```
make UTILS='UTILITY_1 UTILITY_2'
```
Installation Instructions
-------------------------
To install all available utilities:
```
make install
```
To install all but a few of the available utilities:
```
make SKIP_UTILS='UTILITY_1 UTILITY_2' install
```
To install only a few of the available utilities:
```
make UTILS='UTILITY_1 UTILITY_2' install
```
To install every program with a prefix (e.g. uu-echo uu-cat):
```
make PROG_PREFIX=PREFIX_GOES_HERE install
```
To install the multicall binary:
```
make MULTICALL=y install
```
Set install parent directory (default value is /usr/local):
```
make PREFIX=/my/path install
```
Uninstallation Instructions
---------------------------
To uninstall all utilities:
```
make uninstall
```
To uninstall every program with a set prefix:
```
make PROG_PREFIX=PREFIX_GOES_HERE uninstall
```
To uninstall the multicall binary:
```
make MULTICALL=y uninstall
```
To uninstall from a custom parent directory:
```
make PREFIX=/my/path uninstall
```
Test Instructions
-----------------
To simply test all available utilities:
```
make test
```
To test all but a few of the available utilities:
```
make SKIP_UTILS='UTILITY_1 UTILITY_2' test
```
To test only a few of the available utilities:
```
make UTILS='UTILITY_1 UTILITY_2' test
```
To include tests for unimplemented behavior:
```
make UTILS='UTILITY_1 UTILITY_2' SPEC=y test
```
Run busybox tests
-----------------
This testing functionality is only available on *nix operating systems
To run busybox's tests for all utilities for which busybox has tests
```
make busytest
```
To run busybox's tests for a few of the available utilities
```
make UTILS='UTILITY_1 UTILITY_2' busytest
```
To pass an argument like "-v" to the busybox test runtime
```
make UTILS='UTILITY_1 UTILITY_2' RUNTEST_ARGS='-v' busytest
```
