# ORX (OPENRNDR EXTRA)

[![ORX maven badge](https://img.shields.io/maven-central/v/org.openrndr.extra/orx-noise-jvm?style=flat&color=%23FFC0CB
)](https://mvnrepository.com/artifact/org.openrndr.extra)

A growing library of assorted data structures, algorithms and utilities to
complement [OPENRNDR](https://github.com/openrndr/openrndr). 
Multiplatform, unless they deal with hardware or depend on binary libraries. Those are JVM-only.

Find an auto-generated API documentation page at https://orx.openrndr.org/.

## Usage

To make use of these extensions clone the [OPENRNDR template](https://github.com/openrndr/openrndr-template), uncomment the ones you need in its [build.gradle.kts](https://github.com/openrndr/openrndr-template/blob/master/build.gradle.kts) file, and reload Gradle. Cloning this repo is optional but useful to run the demos in each ORX folder, to study the source code, and to contribute to existing or new ORX'es.

# Developer notes

## Publish and use local builds of the library in your applications

First, build and publish [OPENRNDR](https://github.com/openrndr/openrndr) to the local maven repository:

Run (or import in IntelliJ IDEA and edit the run configuration).
```sh
# In openrndr repository
./gradlew publishToMavenLocal snapshot
```

This command will build and publish a snapshot of the next version of the library to your local maven repository.
The exact version will be shown in the console output during the build process.

Now you can run the same command again but for this repository.

```sh
# In orx repository
./gradlew publishToMavenLocal snapshot
```

It will automatically use the locally published snapshot of OPENRNDR for building ORX and will publish ORX to your local
maven repository with the same logic as before.

Once that's done, you can use the local builds of OPENRNDR and ORX in
your [openrndr-template](https://github.com/openrndr/openrndr-template) by specifying the version that was published.

Take a look at the [wiki](https://github.com/openrndr/openrndr/wiki/Building-OPENRNDR-and-ORX) for a more detailed walk-through.
