The CUE Configuration Language

Configure, Unify, Execute

CUE is an open source configuration language which aims to make complex configurations more manageable and usable.

CUE is a constrained-based language. Constraints provide a powerful yet simple alternative to inheritance, a common source of complexity with other configuration languages.

The CUE tooling also provides integrated declarative scripting aimed at simplifying putting configurations to good use while giving static analyis tools maximum domain knowledge.

Some highlights:

  • JSON superset: get started quickly
  • convert existing YAML and JSON
  • declarative scripting
  • automatically simplify configurations
  • formatter
  • arbitrary-precision arithmetic
  • rich APIs designed for automated tooling
  • a formalism conducive to automated reasoning
  • generate CUE templates from source code
  • generate source code from CUE configurations (TODO)
