Yin Language Support

Official editor support for the Yin programming language.

Features

• syntax highlighting for .yin files
• live parser and type-checker diagnostics for unsaved documents
• canonical whole-document formatting
• exact diagnostic ranges and stable Yin diagnostic codes

The extension includes the Yin 0.8.0 language server and communicates with it locally over stdio. Source code is never sent to a remote service.

Requirement

Install Java 17 or newer. If java is not on PATH, set yin.java.path to the full path of a compatible Java executable, then reload the VS Code window.

Formatting

Open a .yin file and run Format Document. To make Yin the default formatter for the language, add:

"[yin]": {
  "editor.defaultFormatter": "smallyunet.yin-language-support"
}

Current scope

Yin 0.8.0 provides diagnostics and formatting. Hover, completion, and go to definition are planned for later editor-service releases.
