So what are we doing? As mentioned in the introduction, we’re going to take a really simple approach to building a compiler and creating executable code following Jack Crenshaw’s “Let’s Build a Compiler” series. Ideally, you’ll follow along, writing this code, assembling the output, and executing on a 6502 emulator somewhere. It will probably get really annoying to keep reading “As in the original articles”, so take it a given that the rest of this series is shamelessly stolen from that wonderful work. Read more...

Introduction From 1988 to 1995, Jack W. Crenshaw put out a fifteen-part series entitiled “Let’s Build a Compiler”. It is a nice introduction to compiler construction. Being a bit dated, I thought it might be a fun project to create a series of similar series of articles using a more modern language. I use Go as my daily driver at work, so I’ll go ahead with that here. I won’t be using proper go idioms, but rather will try to more closely follow the structure of the Turbo Pascal in which the original series was written. Read more...
