Parsing stuff was the first killer app for me in Haskell: suddenly this interesting language actually made my paid work easier than it was before.



Parser combinators provide an embedded language that help you parse stuff easily. I came to this from a sysadmin direction (where I was using a lot of sed and grep) rather than from the abstract theoretical side of parsing, and so I hope my talk will be pretty hands on.



I plan to build a basic parser during the talk as motivation; most likely a parser for JSON.



Level: You won't need to know much Haskell for this. You don't need to know what a parser combinator is already.



If you are already a parser combinator poweruser you won't get much out of it, probably, but come along anyway and throw eggs...
