The "Understanding Parser Combinators" Series

In this series, we'll look at how so-called "applicative parsers" work. In order to understand something, there's nothing like building it for yourself, and so we'll create a basic parser library from scratch, then some useful "parser combinators", and then finish off by building a complete JSON parser.

• Understanding Parser Combinators. Building a parser combinator library from scratch.

• Building a useful set of parser combinators. 15 or so combinators that can be combined to parse almost anything.

• Improving the parser library. Adding more informative errors.

• Writing a JSON parser from scratch. In 250 lines of code.
