README
Parser and pretty printer for Rust 
language-rust aspires to efficiently and accurately parse and pretty print the Rust language. The underlying AST structures are also intended to be as similar as possible to the libsyntax AST that rustc itself uses.
A typical use looks like:
>>> :set -XTypeApplications +t >>> import Language.Rust.Syntax >>> -- Sample use of the parser >>> import Language.Rust.Parser >>> let inp = inputStreamFromString "fn main () { println!(\"Hello world!\"); }" inp :: InputStream >>> let sourceFile = parse' @(SourceFile Span) inp sourceFile :: SourceFile Span >>> -- Sample use of the pretty printer >>> import Language.Rust.Pretty >>> pretty' sourceFile fn main() { println!("Hello world!"); } it :: Doc b Building
Cabal
With Cabal and GHC, run
cabal install happy --constraint 'happy >= 1.19.8' cabal install alex cabal configure cabal build Stack
With the Stack tool installed, run
stack init stack build The second command is responsible for pulling in all of the dependencies (including executable tools like Alex, Happy, and GHC itself) and then compiling everything. If Stack complains about the version of Happy installed, you can explicitly install a recent one with stack install happy-1.19.8.
Evolution of Rust
As Rust evolves, so will language-rust. A best effort will be made to support unstable features from nightly as they come out, but only compatibility with stable is guaranteed. The last component of the version number indicates the nightly Rust compiler version against which tests were run. For example, 0.1.0.26 is tested against rustc 1.26.0-nightly.
Bugs
Please report any bugs to the github issue tracker.
Parser
Any difference between what is accepted by the rustc parser and the language-rust parser indicates one of
- a bug in
language-rust(this is almost always the case) - a bug in
rustc - that there is a newer version of
rustcwhich made a breaking change to this syntax
If the AST/parser of rustc changes, the rustc-tests test suite should start failing - it compares the JSON AST debug output of rustc to our parsed AST.
Pretty printer
For the pretty printer, bugs are a bit tougher to list exhaustively. Suggestions for better layout algorithms are most welcome! The fmt-rfcs repo is loosely used as the reference for "correct" pretty printing.
