Episode notes

The chapter explores the challenges and benefits of incorporating lint rules internally in a tool, using the example of rough in Rust development. It emphasizes simplifying the adoption process and ensuring a smooth user experience by bundling essential linting functionalities. Discussions also touch on the future of linting in Python and Rust, potential AI intersections, and the importance of improving tools like RUF with type inference for enhanced code quality.

Linting is the process of checking source code for programmatic as well as stylistic errors. Ruff is a highly popular Python linter written in Rust. It was developed by Charlie Marsh, who also founded Astral, which is focused on next-generation Python tooling.

Charlie joins the podcast to talk about open source development, Ruff, the UV package installer, and much more.

Josh Goldberg is an independent full time open source developer in the TypeScript ecosystem. He works on projects that help developers write better TypeScript more easily, most notably on typescript-eslint: the tooling that enables ESLint and Prettier to run on TypeScript code. Josh regularly contributes to open source projects in the ecosystem such as ESLint and TypeScript. Josh is a Microsoft MVP for developer technologies and the author of the acclaimed Learning TypeScript (O’Reilly), a cherished resource for any developer seeking to learn TypeScript without any prior experience outside of JavaScript. Josh regularly presents talks and workshops at bootcamps, conferences, and meetups to share knowledge on TypeScript, static analysis, open source, and general frontend and web development.
