Fable Converted Pylint to Rust
Pylint has been converted to Rust, with the new project called "prylint" now available on PyPI. This rewrite aims to improve performance and maintainability of the popular Python linting tool.
Background
- Pylint is a widely used static analysis tool for Python code (linter); it checks for errors, coding standards, and code smells. It's written in Python itself.
- This project, prylint, is a Rust reimplementation of Pylint by the company Fable. The title "Fable Converted Pylint to Rust" means they rewrote the tool in the Rust programming language for better performance.
- Rust is a systems programming language known for speed and memory safety; rewriting Python tools in Rust is a trend to make developer tooling faster (e.g., Ruff for Python linting/formatting, also Rust-based, has gained significant popularity).
- The key context is that Fable (likely the company behind the "Fable" Python course/learning platform) created this as a faster alternative to the original Python-based Pylint. Since the original Pylint can be slow on large codebases, Rust-based linters like Ruff have disrupted the space. Prylint appears to be another entrant trying to bring Pylint's specific checks to Rust-level speed.
