Rob Pike shows how the Go text/template lexer is built, using state functions, goroutines and channels. The talk was given at a Google Technology User Group in Sydney in 2011.
Why Hacker News readers recommend it: HN returns to it for years as an elegant introduction to writing a lexer that is easy to follow even without a parsing background.
