Please consult the Oak manual and this grammar for a more complete example.


  • Grammar description as a Rust syntax extension.
  • Generation of both recognizer and parser functions for each rules.
  • Type inference for each parsing expressions. Simplify the AST construction.

Build local documentation

You might want to build the manual or code documentation from the repository because you need it to be synchronized with a specific version of Oak or simply for offline usage. Here how to do it!

Build the manual

You need the utility mdbook:

cargo install mdbook

Once installed, go inside oak/doc and execute mdbook build -o. The manual is generated inside a local folder named book and directly opened in your browser.

Build the code documentation

As a user of Oak, you will be interested by the runtime documentation.

cd oak/runtime
cargo doc

The documentation is then available in oak/runtime/target/doc.

To build the internal documentation of Oak, you can type this command at the root of the project:

cd oak
rustdoc --document-private-items --output=target/dev-doc src/liboak/lib.rs

The documentation will be available inside oak/target/dev-doc. It is useful to work on Oak :-)
