Starting the Server

The project currently ships the language server as part of the Visual Studio extension. For custom integration, run the built executable as a stdio server and do not write non-LSP log text to its standard output.

dotnet run --project language-tools/AuroraScript.LanguageServer/AuroraScript.LanguageServer.csproj

Workspace Behavior

The server indexes open files and workspace .as files. @global(); declaration files supply diagnostics, completion, and navigation for host globals; they are not importable modules.

@global();

declare func HOST_ADD(left, right);
declare const HOST_NAME;

Available Capabilities

• Diagnostics: open an invalid .as file and let the client show diagnostics.
• Completion: request completion after Array..
• Hover: hover Path.join for its signature and description.
• Definition: go to definition from an import name or function call.
• Formatting: invoke the client's Format Document command.
