Frequently Asked Questions
What is TOML and where is it commonly used?
TOML (Tom's Obvious Minimal Language) is a human-readable configuration file format designed to map unambiguously to a hash table. It is widely used in Rust (Cargo.toml), Python (pyproject.toml), Go (Gopkg.toml), and static site generators.
How do TOML tables map to JSON?
A TOML table header like '[database]' creates a JSON key named 'database' with a nested object containing all key-value pairs listed under that section.
What is the difference between single bracket [table] and double bracket [[table]] in TOML?
Single bracket '[table]' defines a standard nested object/hash table. Double bracket '[[table]]' defines an array of tables, which maps to a JSON array of objects.
