Parsing with Derivatives

Off topic, but he also gave a great talk on parsing with derivatives ▶ this video which was used by the clojure team [link]

In addition to this, I always think about Matt Might's "Parsing with Derivatives." [1] I'll have to read about flap, as it seems to utilize a lexer based on derivatives. [1]: ▶ this video

Yes, I'm scanning the original video introducing derivatives[1]. The need for parsing is ubiquitous yet, Never mind CS students, in my experiences a significant number of professional programmers cannot create a basic parser either from scratch or from a standard tool. Edit: The video picks on hand-written c parser. Such a thing isn't necessarily bad IF it's in a formally derived recursive descent parser. But just ad-hoc parsing without being informed by a grammar is pretty much waiting for disaster. [1] ▶ this video
