gosass 
About
Gosass is a fast sass compiler. We made this because the normal ruby compiler
ran too slowly, and the native compiler (sassc) didn't have all the features
we needed (directory compilation and watching.)
Installation
Gosass depends on sassc, so
install that first. On mac, you can use
homebrew: brew install sassc.
Then install gosass:
go get github.com/dailymuse/gosass
pushd $GOPATH/src/github.com/dailymuse/gosass
make install
popd
Example Usage
# Compile an individual file
gosass -input file.scss -output file.css
# Compile a directory
gosass -input sass/ -output css/
# Live-compile a directory
gosass -input sass/ -output css/ -watch
