Parser Combinators in Haskell

1. pyparsing

   1 13 2,378 8.8 Python

   Python library for creating PEG parsers

   

   Since it is not mentioned in the article: Python users may also want to check out pyparsing [0]. It is slightly different from Parsec/FParsec (for instance, it ignores all whitespace by default), but I think it is a really good project.

6. nom

   5 92 10,062 6.6 Rust

   Rust parser combinator framework

   

   Rust has a parser combinator library called Nom [^1] that is really a joy to use. I know a little Rust—enough to know what a lifetime is but not so much that I don’t have to keep referring to the documentation when building something. It took me just a few hours with the docs and examples to get a decent parser together. So nice to work with combinators!
