The project is in its early stages: contributions are welcome and would be very helpful, but the project is not yet optimized for contributors. Moreover, it is doubly experimental, so there's no guarantee that any work here would reach production. That said, here are some arias where contributions would be especially welcome:
-
Designing internal data structures: RFC only outlines the constraints, it's an open question how to satisfy them in the optimal way. See
ARCHITECTURE.mdfor current design questions. -
Porting libsyntax parser to libsyntax2: currently libsyntax2 parses only a tiny subset of Rust. This should be fixed by porting parsing functions from libsyntax one by one.
-
Writing validators: by design, libsyntax2 is very lax about the input. For example, the lexer happily accepts unclosed strings. The idea is that there should be a higher level visitor, which walks the syntax tree after parsing and produces all the warnings. Alas, there's no such visitor yet :( Would you like to write one? :)
-
Creating tests: it would be tremendously helpful to read each of libsyntax and libsyntax2 parser functions and crate a small separate test cases to cover each and every edge case.
-
Building stuff with libsyntax2: it would be really cool to compile libsyntax2 to WASM and add client side syntax validation to rust playground!
Do take a look at the issue tracker, and try to read other docs in this folder.
