These are the main files included in the first version of Rust - that power only two specific rules. While it cannot be used in a meaningful way, it provides an easy way to understand how ruff (or generally other linter) works without getting into all the details that are not so important for education.
- main.rs
- cache.rs
- check.rs
- lib.rs
- linter.rs
- message.rs
- parser.rs
The first-ever version of Ruff used the following Rust packages
fern: for logging rayon: for parallelizing computation clap: for cli argument parsing serde: for serializing and deserializing data rustpython: for parsing, uses the provided AST colored: for adding colors to the terminal walkdir: for walking a directory recursively anyhow: Flexible concrete Error type built on std::error::Error
logging: std logging library typer: cli argument parsing ast: Python native ast library rich: color terminal os/pathlib: walking directory pytest: write simple tests
- Implement Cache
- Implement parallel processing
- Reimplement in Rust
