Thank you for your interest in contributing to ORX :-)
This repository contains the OPENRNDR extras: a growing library of assorted data structures, algorithms and utilities to complement OPENRNDR. Other repositories you can contribute to are the core OPENRNDR, the guide and the template.
Please read the general information about contributing to OPENRNDR. This document focuses on specific details about the ORX repository.
There are two types of ORX extras:
- JVM only. Subfolders of
/orx-jvm/
. These run only on Desktop (not in web browsers). - Multiplatform. Other
/orx-.../
folders. These run both on Desktop and web browsers.
Each orx folder contains a README.md
, a build.gradle.kts
file and a src
folder.
Please explore several orx directories to get a feel for how they look like.
Gradle tasks are used to update the list of ORX'es in the root README.md, and to update the list of demos in each ORX'es README.md.

Note that inside src
only commonMain
is required.
Assuming you are creating an orx called magic
, the readme should be formatted as follows:
# orx-magic
One or more lines including a short description to display on the root README.md.
One or more lines including a short description to display on the root README.md.
One or more lines including a short description to display on the root README.md.
Main content describing the usage of orx-magic goes here
...
<!-- __demos__ -->
- Start with a markdown header with the name of the orx followed by an empty line.
- One or more lines with a brief description to show on the root
README.md
, followed by an empty line. (ThebuildMainReadme
Gradle task will extract this description and update the rootREADME.md
). - A detailed description (a guide) of how to use the orx, possibly with code examples in code fences like
```kotlin //code example ```
- If the orx includes demos (more below), running the
CollectScreenShots
Gradle task will append<!-- __demos__ -->
to the readme followed by a list of automatically generated screenshots of the demos and links to their source code. This is specially useful for orx'es that produce graphical output, but less so for orx'es that interface with hardware (likeorx-midi
).
ORX build.gradle.kts
files declare their dependencies and most follow the same structure.
Please explore various build files and find the simplest one that matches your use case.
Note that the JVM ones are somewhat simpler than the multiplatform ones.
The plugins
section includes either org.openrndr.extra.convention.`kotlin-multiplatform`
or
org.openrndr.extra.convention.`kotlin-jvm`
depending on the orx type.
The JVM build files declare separate dependencies for the orx itself (implementation
) and for usage demos
(demoImplementation
).
See an example.
The multiplatform build files may have blocks like commonMain
, commonTest
, jvmTest
, jvmDemo
, etc. to specify the dependencies for each case. See an example.
ORX'es often include a jvmDemo
folder. This folder should contain small programs demonstrating
how the ORX can be used. When the build system runs the
CollectScreenShots
task,
the SingleScreenshot()
extension will be injected into each program found inside the jvmDemo
folder, then executed. A PNG screenshot is saved and pushed into the media
brach. Finally, links to those PNG images are inserted into the README.md file of each ORX,
together with a link to the source code that produced the screenshot.
This serves two purposes: it can be useful for the user to see images of what the ORX can produce, while it can also be usefu to detect breaking changes (in case the demo fails to run, or produces a blank image).
