YAMLScript

Next-generation YAML programming language for advanced configuration management.

Overview

YAMLScript is an innovative programming language that extends YAML with computation capabilities. It looks like YAML but can execute code, making it perfect for advanced configuration management.

What is YAMLScript?

YAML + Programming

YAMLScript is:

  • Valid YAML - Any YAMLScript is valid YAML
  • Executable - Can evaluate expressions and run functions
  • Familiar - Uses YAML syntax you already know
  • Powerful - Supports variables, functions, and logic

The Problem YAMLScript Solves

Traditional YAML is static data. YAMLScript adds computation:

Traditional YAML (static): 

database:
  host: localhost
  port: 5432
  url: "postgres://localhost:5432/mydb"  # Redundant!

YAMLScript (computed): 

database:
  host: localhost
  port: 5432
  url: =>"postgres://$host:$port/mydb"  # Computed!
