Language Basics

Nubo is a simple, expressive, real-time language with a syntax inspired by Go and JavaScript. This guide walks you through the basic constructs.

Variables

Use let or const to declare variables:

let name = "Martin"
const age = 18 // not mutable

Functions

Functions are declared with the fn keyword:

fn greet(name) {
  return <h1>Hello, {name}!</h1>
}

Control Flow

If Statement

if age >= 18 {
  return <p>Adult</p>
} else {
  return <p>Minor</p>
}

While Cycle

let inx = 0

while inx < 10 {
    println(inx+1)
    inx++
}

For Loop

Supports both item-only and index+item syntax:

for item in range(3) {
    println(item)
}

for i, item in list {
    println(i, item)
}

HTML Templates

Nubo lets you embed HTML natively:

let name = "World"
return <h1>Hello, {name}!</h1>

To render raw HTML (not escaped), prefix with @:

let html = <b>bold</b>
return <div>@{html}</div>

Components (Preview)

You can use built-in components like this:

import styled from "@std/styled"

let user = nubo.User{ Name: "Martin" }

return <styled.AdminDashboard :user="user">
    <styled.H1>Hello, {user.Name}!</styled.H1>
</styled.AdminDashboard>
