Wow! My eyes popped out for a second when I saw my name there in the README. I wrote an alternative router for Rails (https://github.com/stevegraham/rails/pull/1) because I wanted to be able to generate links to parent and child resources automatically by reflecting on the routing table. I think this would be a useful feature for Hypermedia APIs. I'm currently working on implementing this in a project called Restafarian (https://github.com/stevegraham/restafarian/blob/master/examp...). I couldn't see a way to do this with Journey (The existing Rails router) which is a deterministic finite state automaton, so I wrote one using a modified trie structure where the nodes also have a reference to their parent. It also happened to be a bit faster, which was a nice bonus, but it looks like they've made some changes to bring it to nearly the same performance characteristics.
Hi! your implementation is inspiring to me. so I mixed some other ideas to implement this (for fun and experimentation).
this router library can be used for different purpose (outside of URL dispatching), although we don't gain so much performance from the point of view of each single request.
