LikeC4 Language

LikeC4 is a DSL for describing software architecture. It might look like Structurizr DSL (opens in a new tab), though it is not fully compatible.

The source files must have .likec4 or .c4 extensions.
LikeC4 looks for all source files and merges them into a single model (explained later in Workspace).

A project may look like this:

Top-level statements

Source files should have at least one of these statements:

• specification - defines element kinds to be used in the model, like app, microservice, grapqlMutation...
• model - architecture elements, hierarchies, compositions and relationships
• views - visualizations of the architecture

specification {
  //...
}
 
model {
  //...  
}
 
views {
  //...
}

It is not allowed to have multiple statements of the same kind.

model {
}
 
// ⛔️ not allowed to have multiple statements
model {}

But it is allowed to skip any of them, so you can have only model or only views or only specification or any combination of them.
