dhall: A configuration language guaranteed to terminate

[ bsd3, compiler, library, program ] [ Propose Tags ]

Dhall is an explicitly typed configuration language that is not Turing complete. Despite being Turing incomplete, Dhall is a real programming language with a type-checker and evaluator.

Use this library to parse, type-check, evaluate, and pretty-print the Dhall configuration language. This package also includes an executable which type-checks a Dhall file and reduces the file to a fully evaluated normal form.
