🌽 Corn

A simple and pain-free configuration language.

Corn has been designed using inspiration from JSON and Nix to produce a language that's easy and intuitive to write, good for config files, and has a feature-set small enough you can learn it in minutes. It was born out of the following frustrations:

JSON is not a config language, despite how often people use it as one.
TOML is good for flat structures but gets ugly quickly with deeper objects.
YAML is far too complex and its whitespace rules make it error-prone.
Nix is a full-sized language and not easy to integrate.
