|
||||
Thanks for taking the time to submit a contribution to Velocity! Your support
|
||||
is greatly appreciated.
|
||||
|
||||
In this document, we'll give you some tips on making it more likely your
|
||||
contribution will be pulled.
|
||||
|
||||
# Setting up a development environment
|
||||
|
||||
This isn't as difficult as you may be led to believe. All you need to do is
|
||||
clone the Velocity repository in your favorite IDE and have your backend test
|
||||
servers set up to run behind Velocity.
|
||||
|
||||
# Actually working on the code
|
||||
|
||||
It is strongly recommended that you are familiar with the Minecraft protocol,
|
||||
proficient with using Java, and have familiarity with the libraries used in
|
||||
Velocity (particularly [Netty](https://netty.io), [Google Guava](https://github.com/google/guava),
|
||||
and the [Checker Framework annotations](https://checkerframework.org/)).
|
||||
While you can certainly work with the Velocity codebase without knowing any
|
||||
of this, it can be risky to proceed.
|
||||
|
||||
Velocity does not currently obey any one general code style at the moment.
|
||||
Plans are [in the works](https://github.com/VelocityPowered/Velocity/issues/125)
|
||||
to define the code style the project will follow.
|
||||
|
||||
# Notes on the build
|
||||
|
||||
To reduce bugs and ensure code quality, we run the following tools on all commits
|
||||
and pull requests:
|
||||
|
||||
* [Checker Framework](https://checkerframework.org/): an enhancement to Java's type
|
||||
system that is designed to help catch bugs. Velocity runs the _Nullness Checker_
|
||||
and the _Optional Checker_.
|
||||
* [Checkstyle](http://checkstyle.sourceforge.net/) (not currently in use): ensures
|
||||
that your code is correctly formatted.
