The following are a few tools I have writen to help me to write Brain-Flak code. You can see the original project here
Compress removes all comments whitespace and stray characters that may have been placed while you were writing the code.
Unpack adds whitespace to Brain-Flak code to make it more readable. Unpack splits different units onto different lines and indents inside of the { } and < > monads.
Optimize is the most complicated of the three tools. It takes in some Brain-Flak code and attempts to simplify it to the shortest possible equivalent code using rules it knows.
Optimize is fairly modular.
