semantic-linebreaker

A utility to help you apply semantic linebreaks to any text.

Try it here: http://waldyrious.github.io/semantic-linebreaker

Currently it's simply a dumb pattern-replacement tool, as in merely adds line-breaks indiscriminately after a few punctuation marks (.,:;!?) and before some conjunctions (but, and, or...). Better heuristics are evidently needed. Check the wiki for some potentially useful reesources. Pull requests, issue reports or wiki edits are welcome!
