    What language? Usually there are libraries

    Do you want to write it from the bottom up?

    I don't think there's a definitive list of resources. Start with the spec and learn to optimize as you go

    Most parsers are basically stream decoding state machines with handlers tied to certain transitions.

    Parsers are a programmer's best friend.

    As a corollary: you cannot really call yourself a programmer if you don't know how to write one.

    Besides, they're fun!

    Golang.
    There are more than enough libraries , but they all are using a reflection-based approach for accessing data.
    I'm more of a fan of dom-like interfaces for this.

    @Lor-inc I'm sure he understood every word of that

    As for OP, great resource is this:

    http://lisperator.net/pltut/

    Read the whole thing from start to finish, it will give you a good understanding of how parsers work in general

    @AlgoRythm If he knows what a state machine is (which he might) then the rest is obvious.

    @Lor-inc I thought it was a little silly to assume he did, given his inability to google things
