Setup
1. Install the extension
Press F5 in the project folder to open an Extension Development Host.
2. Set your tokens
Open the Command Palette (⌘⇧P) and run:
- GitMerge: Set GitHub Token — enter a GitHub PAT with
repo scope
- GitMerge: Set GitLab Token — enter a GitLab PAT with
api scope
Tokens are stored securely via VS Code's built-in Secret Storage (never in plaintext settings).
3. Self-hosted GitLab
In Settings → GitMerge Review, change Gitlab Url to your instance, e.g. https://gitlab.mycompany.com.
4. AI Analysis
Requires the GitHub Copilot extension to be installed and authenticated. Click the "Analyze with AI" button in the right-side AI panel.
