SnowyCoder / coldpiler

A playground for a compiler written in rust

Coldpiler

This is a more serious version of compiler-exercises, so it's a toy compiler written in rust. You can find the language it compiles in the LANGUAGE.md file.
To make this project a bit more readable I've divided the project in three parts:

• coldpiler_parser contains the boilerplate code for the lexer and parser
• coldpiler_codegen provides the procedural macros that generate the code for lexer and parser
• coldpiler the heart of the compiler

Dependencies

My plan is to go to 0-dependencies but if you want to use procedural macros syn and quote are almost required, so I consider them (and proc_macro2) as part of the standard library. This is not because of lazyness but because they just provide a good way to remove boilerplate code and they fall out of the scope of this project.

Comments

I've tried to comment the strangest parts of the code but I should come back and explain more of what's going on. That said the strongly-typed nature of rust helps understand more than python, so I'd use this project over the python one to comprehend what I've done.

Future

I plan to transform this project into a real compiler for my own language. The plan is not to use any dependency and to write any nontrivial algorithm/data structure myself.
