Single-language

Doodle is written entirely in Kotlin and so are its apps. Doodle Applications do not use HTML, CSS styles or Javascript libraries. In fact, apps are not aware of the Browser (or Browser concepts) at all, and can be written entirely as common (cross-platform) code in multi-platform setups.

Expressive

Creating expressive, intuitive apps is natural with Doodle. It makes complex rendering easy with powerful, vector-oriented rendering, provides fully customizable layouts and simplifies pointer and keyboard handling.

Simply define your View hierarchy, business logic and go.

Vector Oriented

It is easy to build beautifully detailed UIs with Doodle. All rendering in Doodle is vector-oriented; so ellipses, paths, lines, gradients, affine transforms etc. are as simple to use as images and rectangles.

Precise

Doodle gives you control over all aspects of the UI presentation, including pixel-level positioning, making it easier to precisely control rendering.

Modular

Doodle has several libraries and a collection of modules. This allows selective adoption of various features and helps with bundle size. Apps written with Doodle are also dependency-injected; and there are no global objects or state to make mocking challenging.

Hello World

import io.nacular.doodle.application.Application
import io.nacular.doodle.core.Display
import io.nacular.doodle.core.plusAssign
import io.nacular.doodle.core.view
import io.nacular.doodle.drawing.Color.Companion.Black
import io.nacular.doodle.drawing.text

class HelloWorld(display: Display): Application {
    init {
        display += view {
            size   = display.size
            render = {
                text("Hello, world!", color = Black)
            }
        }
    }

    override fun shutdown() {}
}

fun main() {
    application {
        HelloWorld(display = instance())
    }
}
