history
Project history and usage
dhall-yaml is the Dhall ecosystem package for moving between typed Dhall expressions and YAML. In package-manager terms it matters because it turns Dhall from a configuration language into a practical generator for the YAML files expected by Kubernetes, CI systems, and other infrastructure tools.
Project history
The Hackage metadata for dhall-yaml 1.0.0 identifies Gabriel Gonzalez as author, gives 2019 copyright, and describes the package as both a library and executable tooling for converting between Dhall expressions and YAML. It lives in the dhall-lang/dhall-haskell repository alongside the main Dhall implementation.
Adoption history
dhall-yaml adoption follows Dhall's broader use as a programmable configuration format. Official Dhall documentation teaches generation of JSON and YAML, and its production-use page lists organizations using dhall-to-yaml in infrastructure and application configuration workflows.
How it is used
The package exposes the dhall-to-yaml-ng executable for Dhall-to-YAML conversion and yaml-to-dhall for the reverse direction, with library modules for Haskell callers. It is usually installed as a companion to Dhall when a downstream system still consumes YAML.
Why package nerds care
For package nerds, dhall-yaml is the adapter layer that lets Dhall compete with hand-written YAML without requiring the target ecosystem to understand Dhall. It is small, specialized, and valuable mostly because YAML is everywhere and typed configuration is not.
Timeline
- 2019: dhall-yaml 1.0.0 appears on Hackage with dhall-to-yaml-ng and yaml-to-dhall executables.
- 2026: Official Dhall documentation still presents JSON/YAML generation as a core getting-started workflow.
Related projects
- dhall provides the core language and interpreter.
- dhall-json provides related JSON conversion tooling in the same ecosystem.
