James Kyle (who created Babel) wrote a 'Super Tiny Compiler' that's a really great (low barrier to entry) place to start. The inline docs are super well written, clear and extensive. It's also implemented in JabaScript. It's an amazing learning tool and I really loved reading it! https://github.com/thejameskyle/the-super-tiny-compiler

How long did it take you? The documentation is A+ (it reminds me of this compiler: https://github.com/thejameskyle/the-super-tiny-compiler ).

The author using FizzBuzz as a comical-but-recognizable launching point for demonstrating introducing the basics of programming language implementation and RPLY, and the HN comments being nothing but people yelling about FizzBuzz, is a pretty amazing summary of the state Hacker News comments. It also makes me think next time I have a technical article, I should prepend some controversial statement to it just to generate buzz :V In all seriousness: this is a really cool article, thanks for sharing! I'm not very familiar with RPython or RPLY and it was really cool to see a "real-world" example of it. I actually just read through something similar in JavaScript (https://github.com/thejameskyle/the-super-tiny-compiler). I really should give language implementation a shot one of these days (closest I've come is writing a JSON lexer & parser);

This is also a really good resource: https://github.com/thejameskyle/the-super-tiny-compiler

Its probably a parody of https://github.com/thejameskyle/the-super-tiny-compiler

I added a separate file without any code comments as well. https://github.com/thejameskyle/the-super-tiny-compiler/blob...

This is really quite beautifully done. If you're impatient, go straight to the JavaScript code (but the README is worth reading too): https://github.com/thejameskyle/the-super-tiny-compiler/blob... For someone like me who always goes, "Comments? Meh. The code should be the comments!" it's an eye-opener. The code has a lot of comments. But not this kind: i++; // Increment i It's about 200 lines of actual code plus another 500 lines of comments explaining what is going on. And 75 lines of old-school ASCII header art like you used to see on line printers back in the '60s, just to appeal to old-timers like me. It takes you through tokenizing raw code, parsing the tokens into an AST, transforming the AST into a form the code generator can use, and then generating code from it. A great example of how to teach a concept with a small amount o
