Show HN: Parse JSON with Flex, Bison, and Ruby
- cjhdev 10y agoThis is an example of using Flex and Bison to generate a parser that can be packaged up as a Ruby extension. The subject is JSON because it's LALR compatible and easily recognisable. I've used this technique to produce tools that parse syntax other than JSON. I think it's neat because Flex/Bison is very mature, it works well the the Ruby C API, and the parser produced is self contained (i.e. no runtime components).
