Summary of the YouTube video “Introducing Pickle: Apple’s New Open Source Configuration Language”
Introduction
The video discusses a new alternative to JSON and YAML for configuration called Pickle, developed by Apple and open sourced.
Features of Pickle
- Syntax: Pickle offers a blend of static language and general-purpose programming language features.
- Configurability: It is programmable, scalable, and safe for configuring various types of data.
- Type Annotations: Validation is achieved through type annotations with optional constraints.
- Package Management: Pickle provides a package manager for sharing and importing dependencies.
- Editor Support: Best-in-class IDE integrations, including plugins for popular editors like Visual Studio Code.
Use Cases and Comparison
- Versatility: Pickle can be used to produce static configuration files or embedded within applications.
- Validation: Ensures data validity through type annotations and constraints.
- Benefits: Addressing shortcomings of traditional configuration formats like JSON, YAML, or property lists.
Implementation Details
- Examples: Demonstrates defining configuration schema for a web app using classes, functions, loops, and type annotations.
- Dependencies: Packages can be published and imported using the Pickle Package Manager (PPM).
- Language Bindings: Supports embedding Pickle in various programming languages like Java, Kotlin, and Swift.
Conclusion
The video concludes with excitement over the potential of Pickle as a new tool for configuration management and development, highlighting its unexpected open-source nature from Apple.
