is there an easy way to build only css files from sass files in extjs project without running the whole build process? I know I could create a config file for compass and use compass watch but isn't there a simpler way?
It is possible to use the command "sencha ant sass" to recompile the CSS using Sass. With Sencha Cmd 4 the command "sencha app watch" will also recompile CSS when needed.
Note that simply running "compass watch" no longer works with Ext JS 4.2 since the theme structure changed.
