Have you ever wanted to design your own programming language? It seems like such fun, but if you’ve ever tried you probably got stuck right around the time you read “LLR Decent Parsers and Abstract Syntax Trees.” Traditionally designing your own language was hard because it requires a very specialized set of arcane tools, tools that take a long time to learn and use effectively. But it doesn’t have to be this way. Ohm, a new compact parser toolkit from the team at HARC, lets you build your own languages with simple and clean Javascript.

In this four part series, I’ll show you how to build a complete programming language from scratch in less than 200 lines of code.

This series doesn’t just give you some code. We’ll go through each concept step-by-step. We will design and build each feature for a simple language I’m calling Meow, teaching you what you need to know as we go. You don’t even need to know anything about parsers to get started, just some basic knowledge of JavaScript.

So what are you waiting for? Let’s go!
