Frequently Asked Questions

What is TOML?

TOML (Tom's Obvious Minimal Language) is a configuration file format. It's used by Rust's Cargo.toml, Python's pyproject.toml, and Hugo's config.toml. It's designed to be easy to read and write, with clear mapping to data structures.

What are TOML's advantages over JSON for config files?

TOML supports comments (JSON doesn't), has clearer syntax for nested structures, and is more human-readable. It's also less error-prone (no trailing comma issues). JSON is better when interoperability with APIs and JavaScript is needed.
