Episode notes
Meta's Fixit2 Linter Innovation
- Meta's new linter fixit2 is designed for their massive monorepo and addresses hierarchical config needs.
- It uses concrete syntax trees (CST) for better automated fixing compared to tools like black or flake8.
Hierarchical Config for Mono Repos
- Use hierarchical configurations for multi-team monorepos to apply different linting or formatting rules.
- Automate running formatters like 'ruff' per local configs to manage large codebases efficiently.
FastUI's Declarative Python UI
- FastUI uses a declarative Python syntax mirroring the DOM structure for defining web UI.
- This approach makes UI code visually aligned and easier to understand, similar to Flutter's widget tree.
