🤔 What is RESL?

RESL = Runtime Evaluated Serialization Language

RESL is a modern configuration and serialization language with variables, expressions, and dynamic runtime evaluation designed to solve the limitations of traditional static configuration formats like JSON.

PRONUNCIATION

RESL is pronounced like "wrestle"

🎯 Core Purpose

RESL is designed to bring programming capabilities to config files, eliminating the common problems of repetitive, verbose, and hard-to-maintain configuration files.

🌟 Key Features

• 🔄 Dynamic Configuration: Variables, functions, and computed values
• 📝 Familiar Syntax: Combines the best of JSON, JavaScript, and functional programming
• 🏗️ Flexible Structure: Any expression can be top-level, not just objects
• 📊 Rich Data Types: Strings, numbers, booleans, lists, and maps
• ⚡ Powerful Operations: Binary operations, conditionals, transformations, and more

🎯 Use Cases

RESL is ideal for:

• Application Configuration: Server settings, database connections, feature flags
• Infrastructure as Code: Kubernetes manifests, Docker configurations, CI/CD pipelines
• Dynamic Configurations: Environment-specific settings, computed values, conditional logic
• Data Generation: Test data, mock configurations, templated content
• API Responses: Dynamic JSON generation with computed fields

💡 Philosophy

RESL follows the principle that configuration should be:

• Expressive without being complex
• DRY (Don't Repeat Yourself) through variables and functions
• Maintainable with clear structure and computed values
• Familiar using syntax patterns developers already know
• Efficient producing smaller, more readable files
