Duc - VS Code Extension

A Visual Studio Code extension that opens .duc files as SQLite databases.

Features

• Automatically associates *.duc files with the SQLite Viewer editor
• Uses SQLite Viewer to inspect .duc contents
• Keeps your workflow lightweight (no custom conversion pipeline)

Requirements

This extension depends on the SQLite Viewer extension and declares it as an extension dependency. VS Code will install it automatically when needed.

Usage

1. Install the extension
2. Open a .duc file in VS Code
3. The file will automatically open with SQLite Viewer

Alternatively, you can:

1. Right-click on a .duc file in the Explorer
2. Choose Reopen Editor With...
3. Select SQLite Viewer

How it works

The extension:

1. Declares SQLite Viewer as an extension dependency
2. Sets workbench.editorAssociations default so *.duc opens as sqlite-viewer.view
3. Delegates all data inspection to SQLite Viewer

Troubleshooting

Common Issues

1. A .duc file does not open in SQLite Viewer

   • Use Reopen Editor With... and pick SQLite Viewer
   • Verify SQLite Viewer extension is installed and enabled

2. SQLite Viewer reports invalid database

   • Confirm the .duc file is a valid SQLite database file
