Language Overview

What CCL focuses on

CCL is not trying to be a general-purpose language. Its job is much narrower:

• Define data models in one place.
• Attach generation or serialization-related attributes explicitly.
• Generate equivalent code for target languages.

Main building blocks

Global attributes

Global attributes affect the whole generation process.

#[CCLVersion("1.0.0")]
#[SerializationType("binary")]

See Attributes for scopes, language selectors, and supported attribute names.

Models

Models define the data shape.

model UserInfo {
    Id: int64;
    Username: string;
    Email: string;
    CreatedAt: datetime;
}

Enums

Enums define named integer choices that can be used as field types.

enum UserType : uint8 {
    Unknown,
    Player,
    Admin,
}

model UserInfo {
    Type: UserType = UserType.Player;
}

See Enums for base types, explicit values, and nested model enums.

Per-model attributes

Models can also carry attributes.

[SerializationType("binary")]
[SerializationType("json")]
model GetUsersResult {
    Users: UserInfo[];
}

Current scope

CCL intentionally stays minimal. The current public examples emphasize models and attributes rather than a wide type system.
