OPENRNDR template project

A feature rich template for creating OPENRNDR programs based on Gradle/Kts

The template consists of a configuration for Gradle and an example OPENRNDR program. The Gradle configuration should serve as the go-to starting point for writing OPENRNDR-based software.

If you are looking at this from IntelliJ IDEA you can start by expanding the project tab on the left. You will find a template program in src/main/kotlin/TemplateProgram.kt

You will find some basic instructions in the OPENRNDR guide

Gradle tasks

• run runs the TemplateProgram
• jar creates an executable platform specific jar file with all dependencies
• jpackageZip creates a zip with a stand-alone executable for the current platform (works with Java 14 only)

Cross builds

To create runnable jars for a platform different from the platform you use to build one uses ./gradlew jar --PtargetPlatform=<platform>. The supported platforms are windows, macos, linux-x64 and linux-arm64.

Run other Kotlin programs from the command line

By default ./gradlew run runs a program called TemplateProgram.kt but a different one can be provided as an argument:

To run src/main/kotlin/myProgram.kt

./gradlew -Popenrndr.application=MyProgramKt

To run src/main/kotlin/foo/bar/myProgram.kt (assuming package foo.bar in myProgram.kt)

./gradlew -Popenrndr.application=foo.bar.MyProgramKt

Github Actions

This repository contains a number of Github Actions in ./github/workflows. The actions enable a basic build run on commit, plus publication actions that are executed when a commit is tagged with a version number like v0.* or v1.*.
