Source Swap for VSCodium

Switch between Microsoft Marketplace and Open VSX Registry in VSCodium. VSCodium ships with Open VSX by default, so using the Microsoft Marketplace or other official sources for installing extensions becomes very difficult. Source Swap flips the underlying product.json config between the two registries, and can auto-detect your install and fix file permissions for you.

VSIX Extension

1. One-time Setup

   • Press Ctrl+Shift+P
   • Run Source Swap: Auto-Detect & Setup. It finds your VSCodium install and fixes permissions if needed (see TECHNICAL-DETAILS.md for the manual steps)

2. Use Commands

   • Press Ctrl+Shift+P
   • Type Source Swap: Switch Source or Source Swap: Check Status

3. Restart to Apply

   • Reload the window (Ctrl+Shift+P → "Reload Window") or restart VSCodium so the switch takes effect
   • Some installs only pick up the change after a full restart, a reload isn't always enough

Available Commands

Extension Commands

Press Ctrl+Shift+P (Linux/Windows) or Cmd+Shift+P (macOS):

vsce package

Requirements:

• Node.js
• VSCodium 1.104+
• VSCode Engine: ^1.104.0

Troubleshooting

Permission Denied

Run Source Swap: Auto-Detect & Setup (Ctrl+Shift+P). It detects the file and walks you through fixing permissions. For the manual command, see TECHNICAL-DETAILS.md.

Permissions may need re-fixing after VSCodium updates via your package manager.

File Not Found

Verify your VSCodium installation path matches the platform defaults in TECHNICAL-DETAILS.md, or configure a custom path:

1. Open Settings (Ctrl+, or Cmd+,)
2. Search for "Source Swap: Product Json Path"
3. Enter full path: /your/custom/path/product.json
4. Restart VSCodium

Extension Not Working

If the marketplace doesn't seem to have changed, try a full restart before anything else, a window reload doesn't always pick it up:

1. Reload VSCodium: Ctrl+Shift+P → "Reload Window"
2. Restart VSCodium completely if the reload didn't work
3. Reinstall VSIX file
4. Check console for errors (Help → Toggle Developer Tools)
