There are many open sourced parser implementations available to us in Haskell. Parsec seems to be the standard for text parsing and attoparsec seems to be a popular choice for binary parsing but I don’t know much beyond that. Is there a particular decision tree that you follow for choosing a parser implementation? Have you learned anything interesting about the strengths or weaknesses of the libraries?

    You have several good options.

    For lightweight parsing of String types:

    For packed bytestring parsing, e.g. of HTTP headers.

    For actual binary data most people use either:

    • binary — for lazy binary parsing
    • cereal — for strict binary parsing

    The main question to ask yourself is what is the underlying string type?

    That decision largely determines which parser toolset you’ll use.

    The second question to ask is: do I already have a grammar for the data type? If so, I can just use happy

    And obviously for custom data types there are a variety of good existing parsers:
