WorldEdit/CONTRIBUTING.md

Contributing

Thank you for your interest in contributing to WorldEdit! We appreciate your effort, but to make sure that the inclusion of your patch is a smooth process, we ask that you make note of the following guidelines.

• Target Java 21 for source and compilation. Make sure to mark methods with @Override that override methods of parent classes, or that implement methods of interfaces.
• Use only spaces for indentation. Our indents are 4-spaces long, and tabs are unacceptable.
• Wrap code to a 120 column limit. We do this to make side by side diffs and other such tasks easier. Ignore this guideline if it makes the code too unreadable.
• Write complete Javadocs. Do so only for public methods, and make sure that your @param and @return fields are not just blank.
• Don't tag classes with @author. Some legacy classes may have this tag, but we are phasing it out.
• Make sure the code is efficient. One way you can achieve this is to spend around ten minutes to think about what the code is doing and whether it seems awfully roundabout. If you had to copy the same large piece of code in several places, that's bad.
• Keep commit summaries under 70 characters. For more details, place two new lines after the summary line and write away!
• Test your code. We're not interested in broken code, for the obvious reasons.
• Write unit tests. While this is strictly optional, we recommend it for complicated algorithms.

Additional Notes

If you're submitting a feature, base your code on master and PR against the master branch. If you're submitting a bugfix, base your code on the newest version/* branch, and PR against that same branch.

Checklist

Ready to submit? Perform the checklist below:

1. Have all tabs been replaced into four spaces? Are indentations 4-space wide?
2. Have I written proper Javadocs for my public methods? Are the @param and @return fields actually filled out?
3. Have I git rebased my pull request to the latest commit of the target branch?
4. Have I combined my commits into a reasonably small number (if not one) commit using git rebase?
5. Have I made my pull request too large? Pull requests should introduce small sets of changes at a time. Major changes should be discussed with the team prior to starting work.
6. Are my commit messages descriptive?

You should be aware of git rebase. It allows you to modify existing commit messages, and combine, break apart, or adjust past changes.

Example

This is GOOD:

if (var.func(param1, param2)) {
    // do things
}

This is EXTREMELY BAD:

if(var.func( param1, param2 ))
{
    // do things
}
