Hello, and welcome to the second part of the Writing a Markdown Compiler series! In case you’ve need it, here is Part 1, Intro/Tokenizer and Part 3, Code Generation.
In this part we’ll talk about the second step in compiling: Parsing – also known as Syntactic Analysis. This part has a bit more theory, so it might take some time to digest. Sip some coffee, relax, take yout time, and as long as you don’t rush it you’ll find it’s not hard at all. 🙂

The Beezwax web dev team had a great time at RailsConf at the end of last month. The three days of the conference were packed with interesting talks, necessitating a series of painful triages each day as we selected which to attend and which to leave unseen.

I’ve probably written a hundred render_not_found methods in my life as a Rails dev. Usually they just render a static file under /public, and maybe, if I’m feeling nice, give an XML response. No more!
