The project is in its early stages: contributions are welcome and
|
|
would be **very** helpful, but the project is not *yet* optimized for
|
|
contribution. Moreover, it is doubly experimental, so there's no
|
|
guarantee that any work here would reach production. That said, here
|
|
are some areas 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.md` for 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. Take a look at the
|
|
[libsyntax parser](https://github.com/rust-lang/rust/blob/6b99adeb11313197f409b4f7c4083c2ceca8a4fe/src/libsyntax/parse/parser.rs)
|
|
for "what to port" and at the
|
|
[Kotlin parser](https://github.com/JetBrains/kotlin/blob/4d951de616b20feca92f3e9cc9679b2de9e65195/compiler/frontend/src/org/jetbrains/kotlin/parsing/KotlinParsing.java)
|
|
for "how to port".
|
|
|
|
* 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
|
|
the [./docs](https://github.com/matklad/libsyntax2/tree/master/docs) folder!

If you don't know where to start, or have *any* questions or suggestions,
|
|
don't hesitate to chat at [Gitter](https://gitter.im/libsyntax2/Lobby)!
