Auto-compiling HAML / SCSS

[Timothy Washington]

Hi all, 

I'm trying to find a Clojure solution for auto-compiling HAML and SCSS code. I came across https://github.com/rtircher/lein-haml-sass, but that fails when I try to compile with "lein haml once" or "lein haml auto". Has anyone gotten this setup working? Or is there otherwise any other Clojure solution for this? I'm trying to avoid Guard and it's plug-ins. I'm finding its file watching and auto-compiling not to fire properly on my OSX machine. 

Thanks 

Tim

I never used that lein plugin but the output is quite clear:

> Warning: JRuby home "/Users/timothyw/Tools/jruby-1.4.0" does not exist:

It seems like your jruby home is not properly configured, my favourite
way to achieve this is to use
https://github.com/sstephenson/ruby-build

> LoadError: no such file to load -- rubygems

It seems like you don't have rubygems installed (or misconfigured),
try following this: http://docs.rubygems.org/read/chapter/3

I hope it helps,

toni

Hey Antonio, thanks for responding. 

I guess I'm a bit annoyed that lein-haml-sass, isn't managing it's own 3rd party tools itself. I'll check out the links you mentioned. 

Cheers
