London Ruby User Group:Treetop
Treetop
Roland Swingler has been looking at Treetop. Regular expressions are great but they're unreadable when complex, and there are some things they just can't do. The alternative is to build a language parser - but that's really hard, isn't it? In this talk, I'll try and dispell that idea and show how building little languages in ruby is really simple. I'll show two examples: defining a mini-language from scratch to build XMPP bots, and using it as part of your screen-scraping toolbox.
