The First version of Rust

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

Libraries used for 1st version of ruff

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

Libraries I used for the Python verrsion

logging: std logging library typer: cli argument parsing ast: Python native ast library rich: color terminal os/pathlib: walking directory pytest: write simple tests

Next Step

• Implement Cache
• Implement parallel processing
• Reimplement in Rust
