This is a small library for generating railroad diagrams (like what JSON.org uses) using SVG, with both JS and Python ports.

Railroad diagrams are a way of visually representing a grammar in a form that is more readable than using regular expressions or BNF. They can easily represent any context-free grammar, and some more powerful grammars. There are several railroad-diagram generators out there, but none of them had the visual appeal I wanted, so I wrote my own.

The advice is simple: don’t solve a problem you don’t have. Be rather afraid to create obstacles for the future you. You can’t see the future, but you can make the present as simple as it could be.
