My Haskell Side Quest: RPN Calculator and Monadic Parsing
2025-07-06

In pursuit of a job, the author embarked on a journey into functional programming with Haskell, culminating in building a Reverse Polish Notation (RPN) calculator. The article details the shift from imperative to functional thinking, covering core Haskell concepts like recursive types, lambda functions, and curried functions. It delves into monadic parsing, ultimately resulting in a robust RPN parser. The author highlights the elegance and readability of functional code and the power of monads in handling complex parsing tasks.
