Why WCL?

WCL was created out of my desire to have a language that could express most forms of data in a natural way.

This then enables a lot of different use cases. Detailed configurations, WDoc which lets you model the data in a format that makes sense and then present multiple views on it.

A taste

A document is fields and blocks; a schema declared with decorators validates the structure.

@block("service")
type Service {
  @inline(0)   name: utf8     // service "web" → name = "web"
  @default(80) port: u32
  region: utf8
}

@document
type Config {
  @children("service") services: list<Service>
}

service "web" {
  region = "us-east-1"
}
service "api" {
  port   = 9090u32
  region = "eu-west-1"
}
