9 Parser combinators
This chapter covers
- An algebraic design approach to libraries
- Primitives vs. higher-level combinators
- Using combinators to achieve design goals
- Improving library ease of use with syntactic sugar
- Postponing combinator implementation by first focusing on algebra design
In this chapter, we work through the design of a combinator library for creating parsers. We’ll use JSON parsing as a motivating use case. Like chapters 7 and 8, this chapter is not so much about parsing as it is about providing further insight into the process of functional design.
