Open in Delphi

A Visual Studio Code extension that lets you open the file you're currently editing directly in the Delphi IDE.
Requires DRipExtensions to be installed and configured in Delphi.

In memory of Richard.

       • Command: <path-to-vscode>/code.exe
       • Parameters: --reuse-window --goto "<FILE>:<LINE>:<COL>"

3. Verify Installation:

   • Open a Pascal file in VS Code
