MiniYAML LanguageServer

OpenRA's MiniYAML.LanguageServer is developed to help people working with OpenRA .yaml files, making modding OpenRA a less daunting task.

The project consists of a server application and a VSCode extension communicating via the Language Server Protocol (LSP) to provide the following features inside VS Code:

• Great MiniYAML editing support, including Syntax Highlighting, IntelliSense, Go to Definition, Find All References, etc.
• Navigating inside MiniYAML and to C# (if available).
• Hover information.

How it works

The server is written in C# and provides LSP features for MiniYAML, which is now defined as a custom language.

Syntax highlighting for the custom language is provided by our own MiniYAML TextMate Grammar file.

Parsing:

• For MiniYAML parsing the server currently uses a copy of OpenRA's own internal parser, but the plan is to package that as a NuGet package for simpler use here.
• For C# parsing the server uses Roslyn's Syntax Trees.
