Literal

bool

The bool is a built-in type, you can use it to define a variable, true and false is boolean value.

let a: bool = true;
let b = false;

number

In Navi Stream, we use number for all numeric values, including integer and floating point numbers.

let a: number = 1;
let a = 3.1415;

string

We can use double quotes " and ` to create a string literal.

let a = "hello world";
let b: string = `你好世界`;

nil

nil is a special value, it means nothing, it is used to represent a null value.

let a = nil;

color

Unlike most programming languages, we have a color type in Navi Stream, which is used to represent colors for chart drawing.

It is like CSS syntax, we can use # to define a color, and then use HEX color or predefined color names like red, blue, green that CSS supports.

INFO

You can free to use any color, Navi Stream will not process the color, it will output the color to the chart directly.

let a: color = #ff00ff;
let b = #red;
