Note: This document at present is for only code contributors. We should expand it so that it covers reporting bugs, filing issues, and writing docs.
We have a Discord server to discuss Libplanet. There are some channels for purposes:
- #libplanet-users: Chat with game programmers who use Libplanet. Ask questions to use Libplanet for your games.
- #libplanet-dev: Chat with maintainers and contributors of Libplanet. Ask questions to hack Libplanet and to make a patch for it.
- #libplanet-users-kr: The same purpose to #libplanet-users, except you can speak Korean instead English here.
If you use Linux or macOS you need Mono, which provides C# compiler and
.NET VM. You could install it by
sudo apt install mono-devel command
if you use Ubuntu Linux. If you use macOS and Homebrew, you can install
brew cask install mono-mdk command.
If you are on Windows you need things like C# compiler included in Build Tools for Visual Studio 2017. Choose the following workloads during installation:
.NET desktop build tools
.NET Core build tools
These tools should bring MSBuild, the Libplanet project uses to build, as well.
msbuild is available on the shell or Command Prompt. If it fails
to find command named
msbuild it might be not installed correctly or its
directory might be missing in the
Unless you already have your favorite setup, we recommend you to use Visual Studio Code. It is free, open source, and made by Microsoft, which made .NET as well. So Visual Studio Code has a first-party C# extension which works well together.
The following command installs dependencies (required library packages) and builds the Libplanet project:
msbuild -r Libplanet
We write as complete tests as possible to the corresponding implementation code. Going near to the code coverage 100% is one of our goals.
The Libplanet solution consists of 4 projects. Libplanet and Libplanet.Stun are actual implementations. These are built to Libplanet.dll and Libplanet.Stun.dll assemblies and packed into one NuGet package.
Libplanet.Tests is a test suite for the Libplanet.dll assembly, and Libplanet.Stun.Tests is a test suite for the Libplanet.Stun.dll assembly. Both depend on Xunit, and every namespace and class in these corresponds to one in Libplanet or Libplanet.Stun projects. If there's Libplanet.Foo.Bar class there also should be Libplanet.Tests.Foo.BarTest to test it.
To build and run unit tests at a time execute the below commands:
msbuild -r -t:Build,XunitTest Libplanet.Tests msbuild -r -t:Build,XunitTest Libplanet.Stun.Tests
Please follow the existing coding convention. We are already using several
static analyzers. They are automatically executed together with
and will warn you if there are any style errors.
You should also register Git hooks we commonly use:
git config core.hooksPath hooks
We highly recommend you to install an extension for EditorConfig in your favorite editor. Some recent editors have built-in support for EditorConfig, e.g., Rider (IntelliJ IDEA), Visual Studio. Many editors have an extension to support EditorConfig, e.g., Atom, Emacs, Vim, VS Code.
