About:
Pkl is a configuration as code language that can be used to generate static configuration files for various formats. It allows users to define configuration data using a familiar programming syntax, enabling validation, templating, and composition of complex configurations. This CLI tool enables the evaluation of Pkl modules into standard configuration formats like JSON, YAML, or properties files.
Key Features:
  • Strongly typed configuration language
  • Template and reuse configuration logic
  • Export to JSON, YAML, and other formats
  • Validation and constraint checking
Use Cases:
  • Generating environment-specific configuration files
  • Validating complex application configurations
  • Managing configuration for infrastructure as code
Alternatives:
  • cue – CUE is a more established language with similar goals, while Pkl offers a more familiar syntax for users coming from Java/Kotlin ecosystems
  • jsonnet – Jsonnet is a data templating language, whereas Pkl focuses more on configuration as code with built-in validation and schema definitions
