Thanks, very cool! The only problem I had is that if you mark your code with a tab, it trims the first three letters off. I made a little tweak, then used it to make https://github.com/rmosolgo/aiddata-codes.

(although I ran grep -E '^[[ctl-V + TAB]]' > app.rb to get a heroku-deployable version)

@rmosolgo Hi! Gist doesn't seem to do notifications, but I've updated the script to handle tabs. Basically I've dropped the map completely (because ruby doesn't care about whitespace).

Had a look at your projects, love the use of litrb with sinatra! 👍
