TTheme is a YAML/JSON to PLIST/TMTHEME converter, heavily based off of Aroma.
I built this to generate Oblivion colour schemes much faster, allowing me to iterate current versions and generate variations with little work.
$ ttheme -c tests/oblivion.ttheme.js
$ ttheme -o src -c output
$ ttheme -w
$ ttheme -e "plist"
npm install -g ttheme
