Yin Language Support

Official editor support for the Yin programming language.

Install from the Visual Studio Marketplace.

Features

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

The extension starts the Yin 0.21.1 Rust language server locally over stdio. Source code is never sent to a remote service.

Requirement

Install the yin executable from the matching GitHub Release. If it is not on PATH, set yin.path to its full path, 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": "smallyu.yin-language-support"
}

Current scope

Yin 0.21.1 provides diagnostics and formatting. Hover, completion, and go to definition are planned for later editor-service releases.
