Ruud’s Configuration Language

Why another config language? Because:

  • HCL is too ad-hoc to be suitable for any serious abstraction (setunion is variadic so it only works with a statically known number of sets; flatten recursively flattens so it can’t be typed properly and breaks generic code, for comprehensions can’t do nested loops, for_each syntax is bolted on, etc.)

  • Nix-the-language is great but forces the entire Nix store on you when all I want is to evaluate expressions.

  • Python is great but requires some boilerplate for doing the IO if you want to use it as a configuration language.

  • Dhall has the right ideas but the syntax and heavy use of Unicode symbols make it look ugly.

  • CUE and Nickel were not invented here.
