I've been working on the DSL (originally at [1]), as has Randall [2] and no doubt others. It's reaching the point where I think directories and line comments will be useful. So I've set up a full-fledged repo at: https://github.com/ahgittin/heat-hot-dsl-prototyping Directories might be a useful way to keep multiple "live" variants to compare. Plus I think keep using the etherpad for top-level discussion. https://etherpad.openstack.org/heat-dsl-questions --A [1] original- https://gist.github.com/hardys/5408410 (included) [2] randall- https://gist.github.com/rs-randallburt/5437967#file-wordpress-dsl-template (being merged)
