Fancy™ kotlin syntax for oωo-lib

Pros	Cons
Greater flexibility	Limited support for oωo-lib features
Fancy™ syntax	Updates arrive later than oωo-lib
Uses kotlin	Performance slightly lower than oωo-lib

Setup

In your build.gradle file, add these lines:

repositories {
    maven { url "https://api.modrinth.com/maven" }
}

dependencies {
    modImplementation include("maven.modrinth:kowo-lib:0.12.10+1.21")
    // only if you plan to use owo-config
    // annotationProcessor "io.wispforest:owo-lib:0.12.10+1.21"
}

Example usage

class ButtonTestScreen : BaseKowoScreen<FlowLayout>() {
    override fun createRoot(horizontalSizing: Sizing, verticalSizing: Sizing): FlowLayout {
        return Containers.verticalFlow(horizontalSizing, verticalSizing)
    }

    override fun build() {
        // like rootComponent, but better
        root {
            // components can be stored in variables...
            val exampleLabel = label {
                text("Example screen: 0".literal())
            }

            // or directly added to the root
            button {
                message = "Example button".literal()

                // variables can be stored within components
                var value = 0
                onPress {
                    // components stored in variables can be modified
                    exampleLabel.text("Example screen: ${++value}".literal())
                }
            }
        }
    }
}
