Pudl is a simple, lightweight, and easily customizable programming language. Go check it out!

Pudl is written using LLVM, the amazing compiler project. I've built this project off of the great work done by Max Balushkin. His approach to building a language without relying on a third party parser/lexer combo - such as Bison/Flex, ANTLR, etc. - intrigued me. Although, I'm changing a lot of the code to fit my needs, Balushkin's work still gave Pudl a huge jump start.

Expect more changes to Pudl in the future. This project is entirely for fun, so progress may be slow.
