What is TOML?
TOML (Tom's Obvious, Minimal Language) is designed to be a highly readable and straightforward configuration file format. It maps cleanly to a hash table, making it a favorite for modern packaging and build systems such as Rust's Cargo.toml and Python's pyproject.toml. Using a formatter ensures consistent structure, clean spacing, and strict adherence to syntax specifications.
