Apple’s PKL: The Programmable, Scalable, and Safe Configuration Format

Introduction

Apple introduces PKL, a revolutionary file format aimed at providing a programmable, scalable, and safe solution for configuration management. PKL offers seamless integration with various programming languages, robust IDE support, and advanced error detection capabilities. In this blog post, we’ll delve into the features and benefits of PKL and explore how it simplifies configuration management for developers.

Programmable, Scalable, and Safe

PKL offers a modern approach to configuration management, allowing developers to define configuration data in a concise and expressive manner. Let’s take a look at an example comparing PKL with other conventional formats:

Example: bird configuration

With PKL you can generate output for JSON, YAML, Property Lists and other configuration formats.

Integrated Application Configuration

Embed PKL into your applications for runtime configuration, and receive code generation for popular programming languages such as Java, Kotlin, Swift, and Go. This ensures type safety and eliminates the risk of configuration-related runtime errors.

Incredible IDE Integration

PKL offers excellent tooling for writing configurations with the same ease as a statically typed language. It provides plugins and extensions for popular IDEs such as IntelliJ, Visual Studio Code, and Neovim, with Language Server Protocol support coming soon. This ensures a seamless development experience and helps catch errors before deployment.

IDE Error Detection

Conclusion

PKL revolutionizes configuration management with its programmable, scalable, and safe approach. By offering seamless integration with various programming languages, advanced error detection capabilities, and incredible IDE support, PKL empowers developers to streamline their configuration workflows and build more robust applications. Try PKL today and experience the future of configuration management.
