watch single file and compile if a dependency changes about grunt-contrib-stylus HOT 3 CLOSED

The stylus command line watcher knows how to process the stylus dependency tree because it was built for stylus. Watch is a general use utility--it doesn't know how to trace dependencies for every type of input you might ultimately invoke a task for. You'll need to provide the dependency listing yourself. Thankfully, Grunt has great built-in utilities for handling complex globbing: http://gruntjs.com/configuring-tasks

Whoops, the link I meant to send was:

Thanks, I managed to do this :)
watch files: 'source/**/*.styl' and bind it to a stylus task with src: [ 'main.styl']
