TOML

TOML (Tom's Obvious, Minimal Language) is a configuration file format designed to be easy for humans to read and write, with a clear and unambiguous syntax. It is commonly used for application configuration files, such as in software projects, due to its simplicity and readability compared to formats like JSON or YAML. TOML supports data types like strings, integers, floats, booleans, arrays, and tables, making it versatile for structured settings.

Also known as: Tom's Obvious Minimal Language, TOML config, toml, Toml, TOML parser

Why learn TOML?

Developers should learn and use TOML when they need a human-readable configuration format for projects, especially in scenarios like setting up build tools, package managers, or application settings where clarity is prioritized over complexity. It is widely adopted in tools like Cargo for Rust, Poetry for Python, and many CI/CD pipelines, making it essential for working with modern development ecosystems that rely on straightforward configuration management.
