In order to add handlebars to Textmate2 you need to clone the git to
~/Library/Application Support/TextMate/Managed/Bundles
Question
Are there any Textmate 2.0 bundles that are available for Handlebars, Ember, or both?
I did find the following:
https://github.com/drnic/Handlebars.tmbundle
but it hasn't been updated in 2 years and I couldn't really get to work for me effectively in Textmate 2 (although it's possible my way of hacking it in was the problem).
