Parser Combinators

mpc is a Parser Combinator library I have written. This means it is a library that allows you to build programs that understand and process particular languages. These are known as parsers. There are many different ways of building parsers, but the cool thing about using a Parser Combinator library is that it lets you build parsers easily, just by specifying the grammar … sort of.

Many Parser Combinator libraries actually work by letting you write normal code that looks a bit like a grammar, not by actually specifying a grammar directly. In many situations this is fine, but sometimes it can get clunky and complicated. Luckily for us mpc allows us to write normal code that just looks like a grammar, or we can use special notation to write a grammar directly!
