Hi, I'm looking through the Merb::Routing code and I've found a regexp that I can't figure out how it works.
Merb::Router::SECTION_REGEXP #=> /(?::([a-z*_]+))/ It takes a route definition string, like "/products/:model/:id" and extracts the "model" string on the first pass, and later the "id" string. Can anyone shed some light on what the ?:: part does? I haven't found it in any of the documentation for Ruby Regexps that I've found. Cheers Daniel
