Color-Coded `svn status`

First there was: http://snipplr.com/view/15246/color-coded-svn-status

Then there was: http://snipplr.com/view/16540/color-coded-svn-status-v2

A few days ago, I found a handy script online that colorized the output of SVN status. It worked pretty well, but needed a little polish and a couple of tweaks to make it use more common Python idioms. As I continued to use it and fix bugs and inefficiencies, I ended up replacing nearly every line in the original, but it was still a great starting point.

Additional changes include ANSI word-wrapping, a configurable tab expansion feature (for better code alignment), the 'colorizedSubcommands' sequence so that only applicable commands get colorized, use of proper subprocess module calls so that piping through less will work (for example, try svn-color diff | less -r to see colorized diff output).

To use, stick it somewhere, make executable (chmod 755), and then add this to your .profile:

alias svn=/usr/local/bin/svn-color.py

I hope you find my modifications useful. You can modify the colors used by looking up the ANSI color codes for your preferred color scheme and editing the 'statusColors' dictionary. Here's a useful reference for ANSI color values:

Requires Python 2.4 or greater.

Great work

Hi,

Thnx for script. On my Ubuntu 16 output is a bit corrupted:

I changed from
return ''.join(("\001\033[", statusColors[color], "m", line, "\033[m\002"))
to
return ''.join(("\033[", statusColors[color], "m", line, "\033[m"))
and it works...

Thanks for the gist and thanks to @yudjin87 for the fix!

thank you @yudjin87 and @philchristensen
