About:
dhall-yaml is a command-line tool and library for converting between Dhall configuration files and YAML. It allows you to write Dhall expressions, which are typed and composable, and then export them as standard YAML for use with other tools. This provides a safer, more maintainable way to manage configuration by leveraging Dhall's features.
Key Features:
  • Bidirectional conversion between Dhall and YAML
  • Preserves data types and structure during conversion
  • Can be used as a standalone command-line tool or as a Haskell library
  • Integrates with the Dhall ecosystem for configuration management
Use Cases:
  • Generating Kubernetes manifests from typed Dhall templates
  • Managing complex application configuration files with Dhall's type system
  • Validating YAML structure before deployment using Dhall's type-checking
Alternatives:
  • yq – yq is for querying and manipulating YAML/JSON directly, while dhall-yaml uses Dhall as an intermediate, typed language for generating and managing configs.
  • jsonnet – Jsonnet is a data templating language similar to Dhall, but dhall-yaml specifically bridges the Dhall ecosystem to YAML formats.
