Where could I find more examples of using PetitParser?

Question

I'm looking for additional examples of using PetitParser beyond PPArithmeticParser and PPLambdaParser that are provided in the tests package and a couple of blog posts by Lukas? If anyone's willing to share theirs, it would be much appreciated.

Answer 1

Have a look at the official PetitParser code repository, there are many grammars ready to download:

• PetitCSV
• PetitJson (well tested, builds Smalltalk objects)
• PetitMSE
• PetitManifestMf
• PetitRegex
• PetitSQL
• PetitSmalltalk (well tested, can be used as a replacement for the refactoring engine parser)
• PetitXml (well tested)

Additionally you find various PetitParser grammars on SqueakSource. Just search for 'PetitParser' as a keyword and you find more or less complete grammars for Java, JavaScript, Ada, SQL, and some others.

Answer 2

There are a lot of small nice examples on PetitParsers Google+ site.

• Quickly extract all JavaDoc comments from a file
• Parse 'self', but not variables like 'selfish' or 'selfism'
• A PetitParser grammar that only accepts an even number of a's and b's
• Parse a non context-free language
• Parse floating point numbers
• Parse nestable Haskell comments
