When looking for information on getting started with learning how to build an interpreter or compiler, inevitably two resources come up. First, the canonical compiler resource, the Dragon Book, and second, the noob guide, Let's Build a Compiler (LBaC) by Jack W. Crenshaw.

So rather than spending time and money diving into the deep end, I decided to start with LBaC. I don't have a CompSci degree so I need to start at the very beginning and LBaC seems to fit the bill.

However there was one problem with LBaC:

This is a "learn-by-doing" series. In the course of the series I will be performing experiments on a computer. You will be expected to follow along, repeating the experiments that I do, and performing some on your own. I will be using Turbo Pascal 4.0 on a PC clone.

Yep, this series was written way back in the 90's when Turbo Pascal was cool. Thankfully the theory and basic practices are still relevant.

So why Haskell?

First and formost because it is my Language of the Year, and considering I have done nothing with it in the last 6 months, I owe it to myself to actually start a project in Haskell.

Secondly there is extensive tools for more advanced compiler writing such as parsers, lexers and LLVM bindings etc.

Following along

I will be writing these articles as I work my way through LBaC in my spare time as and when I can find it, so they may be a little few and far between.

All code, and these articles, will be available on Github. You will also need LBaC (PDF Version) and the Haskell Platform.
