Pegex::Tutorial(3)

✨ Pegex Tutorials ✨

Okay bestie, welcome to Pegex::Tutorial(3)! 💖 This is your little index page, and it's giving "table of contents but make it cute."

Pegex has a growing number of tutorials on how to do various parsing tasks, and this document is just an index to the current tutorials. No cap. 🫶

🌈 Pegex::Tutorial::JSON 🌈

This one is a very in-depth tutorial about the creation of the module Pegex::JSON — a JSON decoder that uses Pegex — and all the thought that went into creating it. It covers almost all of the Pegex::Syntax as well. Obsessed. ✨

🎀 Pegex::Tutorial::Calculator 🎀

Pegex comes with an eg/ directory. One example is eg/calculator/calculator1.pl in Pegex. It's a simple precedence parser (and evaluator) for arithmetic expressions like this one:

1 * (2 + 3) / (4 ^ 5 ^ 6 - -7)
