A script that monitors your directories and minifies any JS or CSS it finds. Requires Python 2.5+, no Python 3 support yet.
GPL v2 license.
Create a .mash file in the root of your project:
# lines starting # are ignored
static/js
static/css
# You can also use regular expression to mark your directories
static/dev/(js|css)
# Note you have to explicitly specify subdirectories
static/js/[^/]*/libs
static/js/[^/]*/libs/morelibs
Then just fire up MashedPotato, and ... that's it! MashedPotato will monitor those directories, and automatically reminify any modified files.
