## What it is
The official repository for the TOML (Tom's Obvious, Minimal Language) specification, a minimal, human-readable configuration file format that maps unambiguously to a hash table. It hosts the in-development spec, a language-agnostic test suite, and a wiki cataloging implementations, validators, and tooling across many languages.

## Use cases
- define a standard config file format for my application
- find a TOML parser or encoder for my language
- validate TOML files against the spec
- compare TOML with YAML, JSON, and INI for configuration
- test a TOML decoder against the official test suite
- learn TOML syntax and semantics

## When to choose
- you need a human-friendly config format with comments and clear semantics
- you want a format that maps cleanly to hash tables and parses easily in many languages
- you need a standardized, well-specified alternative to INI or YAML for configuration

## When to avoid
- you need to serialize arbitrary data structures or stream data between processes
- you need top-level arrays or floats in your data files
- you want a data-interchange format like JSON for machine-to-machine communication

## Facets
- artifact type: learning-resource
- maturity: stable
- function: serialization, configuration-management, parser, developer-tools
- domain: developer-tools, programming-languages, files, documentation
- platform: cross-platform
- tags: toml, config-file-format, specification, data-format, human-readable
