Rust compiler plugin that generates relatively readable AST for inspection

Language: Rust

Build Status

Mistakes were made!

So I kind of impulsively added this to, without thinking too much about adding more functionality, so if you've got a project that you want to name ast-debug and think would be awesome than this, let me know and we'll work out a way for your project to replace mine.


This compiler plugin takes a function and adds a println! to the top of it which a string that contains the AST of the function when it's passed through the Rust parser.


#[plugin] extern crate ast_debug;

ast!(fn foo() {
	println!("Hello world!");


fn foo() {
	println!(" /* A lot of somewhat pretty printed AST info ends up here! */ ");
	println!("Hello world!");

Current Issues

Compiler plugins are currently an unstable feature, so you'll need the nightly version of Rust to use them. The current code also ends up stripping away a bit of the function data, namely the ABI, unsafe, and the generics. These will probably be fixed eventually!
