Welcome to the official TOML wiki! This is a space for the community to catalog various TOML-related projects. We'd love you to contribute!

Rules

  • Be careful when editing this document. It's a valuable resource, so proofread your work and make sure it's right.
  • Listings are alphabetical, please add your project in the correct order.
  • Keep being your awesome self!

Implementations

Feel free to add your implementation to this list! Please note the highest TOML version tag that your parser supports in your README.

The TOML project maintains a language agnostic test suite at toml-test. It's recommended to add an integration for this.

See Old for a list of old unmaintained implementations.

Projects on this list have not been carefully vetted by the TOML project, and anyone can edit this wiki. The usual due diligence to importing dependencies applies.
