vec/map Expression

GLuaX provides concise syntax for initializing vectors and maps. You can optionally specify type parameters using ::<type>.

Note: The syntax for initializing a vector or map looks very similar to class initialization in GLuaX. The difference is that the compiler detects when you are initializing a map or vec and parses it differently.

Tip: It is recommended to write the curly braces directly after map or vec (e.g., map{...} or vec{...}), and not with a space like map {...}. This helps visually and syntactically distinguish map/vector initialization from class initialization.

Vector Initialization

A vector can be initialized with a list of values:

vec{1, 2, 3}

You can also specify the element type explicitly:

vec::<number>{1, 2, 3}

Map Initialization

A map is initialized with key-value pairs using curly braces and colons:

map{
    1: 1,
    2: 2,
}

You can optionally specify the key and value types:

map::<number>{
    1: 1,
    2: 2,
}

map::<number, number>{
    1: 1,
    2: 2,
}

Example Usage

let numbers = vec{1, 2, 3};
let mapping = map{
    1: "one",
    2: "two",
    3: "three",
};
