TOML in Practice

TOML is the configuration format for Rust's Cargo package manager (Cargo.toml), Python's pyproject.toml (PEP 518), and many other tools. When formatting TOML, the key rules are: use consistent indentation in inline tables, keep arrays of tables ([[table]]) together, and put the [package] section first. The taplo formatter is the standard tool for TOML formatting.
