Contribution Guide

There are many ways to be an open source contributor, and we're here to help you on your way! You may:

  • Propose ideas in our discord
  • Raise an issue or feature request in our issue tracker
  • Help another contributor with one of their questions, or a code review
  • Suggest improvements to our Getting Started documentation by supplying a Pull Request
  • Evangelize our work together in conferences, podcasts, and social media spaces.

This guide is for you.

Development Prerequisites

UPDATE TABLE OF PROJECT DEPS AND INSTALLATION NOTES

Requirement Tested Version Installation Instructions
Go 1.17.6 go.dev

Java 17.0.2 Below, recommended via SDKMan

Go

This project is written in Go, a modern, open source programming language.

You may verify your go installation via the terminal:

$> go version
go version go1.17.6 darwin/amd64

If you do not have go, we recommend installing it by:

MacOS

Homebrew
$> brew install go

Linux

See the Go Installation Documentation.

Mage

The build is run by Mage.

You may verify your mage installation via the terminal:

$> mage --version

built with: go1.17.6

MacOS

Homebrew
$> brew install mage

Linux

Installation instructions are on the Magefile home page.

Java

This project is written in Java, a typesafe, compiled programming language.

You may verify your java installation via the terminal by running java -version.

If you do not have Java, we recommend installing it via SDKMan. This is a project which will allow you to easily install the Java Development Kit (JDK), runtime (JRE), and related frameworks, build tools, and runtimes.

After you've installed SDKMan, you may install Java:

SDKMan (cross-platform instructions)

$> sdk install java 
 ...
Do you want java 17.0.2-open to be set as default? (Y/n): Y
Setting java 17.0.2-open as default.

You may test your installation:

$> java -version
openjdk version "17.0.2" 2022-01-18
OpenJDK Runtime Environment (build 17.0.2+8-86)
OpenJDK 64-Bit Server VM (build 17.0.2+8-86, mixed mode, sharing)

NOTE

You may additionally look for other Java versions to install by running sdk list java:

...or other installation candidates like Apache Ant, Apache Maven, etc, by running sdk list.

Consult the SDKMan documentation for more info.


Build (Mage)

$> mage build

Build (Java / Gradle)

macOS / Linux

$> ./gradlew build

Windows

$> gradlew.bat build

Test (Mage)

$> mage test

Test (Java / Gradle)

macOS / Linux

$> ./gradlew test

Windows

$> gradlew.bat test

NOTE

You may also combine Gradle build targets in one call, like:

$> ./gradlew clean build test

Communications

Issues

Anyone from the community is welcome (and encouraged!) to raise issues via GitHub Issues.

Discussions

Design discussions and proposals take place in our discord.

We advocate an asynchronous, written debate model - so write up your thoughts and invite the community to join in!

Continuous Integration

Build and Test cycles are run on every commit to every branch on GitHub Actions.

Contribution

We review contributions to the codebase via GitHub's Pull Request mechanism. We have the following guidelines to ease your experience and help our leads respond quickly to your valuable work:

  • Start by proposing a change either in Issues (most appropriate for small change requests or bug fixes) or in Discussions (most appropriate for design and architecture considerations, proposing a new feature, or where you'd like insight and feedback)
  • Cultivate consensus around your ideas; the project leads will help you pre-flight how beneficial the proposal might be to the project. Developing early buy-in will help others understand what you're looking to do, and give you a greater chance of your contributions making it into the codebase! No one wants to see work done in an area that's unlikely to be incorporated into the codebase.
  • Fork the repo into your own namespace/remote
  • Work in a dedicated feature branch. Atlassian wrote a great description of this workflow
  • When you're ready to offer your work to the project, first:
  • Squash your commits into a single one (or an appropriate small number of commits), and rebase atop the upstream main branch. This will limit the potential for merge conflicts during review, and helps keep the audit trail clean. A good writeup for how this is done is here, and if you're having trouble - feel free to ask a member or the community for help or leave the commits as-is, and flag that you'd like rebasing assistance in your PR! We're here to support you.
  • Open a PR in the project to bring in the code from your feature branch.
  • The maintainers noted in the CODEOWNERS file will review your PR and optionally open a discussion about its contents before moving forward.
  • Remain responsive to follow-up questions, be open to making requested changes, and... You're a contributor!
  • And remember to respect everyone in our global development community. Guidelines are established in our CODE_OF_CONDUCT.md.
