Sourcegraph integration

Version history
On self-managed GitLab, by default this feature is available. To hide the feature, ask an administrator to disable the feature flag named sourcegraph. On GitLab.com, this feature is available for public projects only.

Sourcegraph provides code intelligence features, natively integrated into the GitLab UI.

For GitLab.com users, see Sourcegraph for GitLab.com.

For an overview, watch the video Sourcegraph’s new GitLab native integration.

note
This feature requires user opt-in. After Sourcegraph has been enabled for your GitLab instance, you can choose to enable Sourcegraph through your user preferences.

Set up for self-managed GitLab instances

Before you can enable Sourcegraph code intelligence in GitLab you must: configure a Sourcegraph instance with your GitLab instance as an external service.

Set up a self-managed Sourcegraph instance

If you are new to Sourcegraph, head over to the Sourcegraph installation documentation and get your instance up and running.

If you are using an HTTPS connection to GitLab, you must configure HTTPS for your Sourcegraph instance.

Connect your Sourcegraph instance to your GitLab instance

  1. Navigate to the site Admin Area in Sourcegraph.
  2. Configure your GitLab external service. You can skip this step if you already have your GitLab repositories searchable in Sourcegraph.
  3. Validate that you can search your repositories from GitLab in your Sourcegraph instance by running a test query.
  4. Add your GitLab instance URL to the corsOrigin setting in your site configuration.

Configure your GitLab instance with Sourcegraph

  1. On the top bar, select Menu > Admin.
  2. On the left sidebar, select Settings > General.
  3. Expand the Sourcegraph configuration section.
  4. Check Enable Sourcegraph.
  5. Set the Sourcegraph URL to your Sourcegraph instance, such as https://sourcegraph.example.com.

Sourcegraph administration settings

Enable Sourcegraph in user preferences

Sourcegraph user preferences

Using Sourcegraph code intelligence

Once enabled, participating projects display a code intelligence popover available in the following code views:

  • Merge request diffs
  • Commit view
  • File view

When visiting one of these views, you can now hover over a code reference to see a popover with:

  • Details on how this reference was defined.
  • Go to definition, which navigates to the line of code where this reference was defined.
  • Find references, which navigates to the configured Sourcegraph instance, showing a list of references to the highlighted code.

Sourcegraph for GitLab.com

Sourcegraph powered code intelligence is available for all public projects on GitLab.com.

Support for private projects is not yet available for GitLab.com; follow the epic &2201 for updates.

Troubleshooting

Sourcegraph isn’t working

If you enabled Sourcegraph for your project but it isn’t working, Sourcegraph may not have indexed the project yet. You can check for Sourcegraph’s availability of your project by visiting https://sourcegraph.com/gitlab.com/<project-path>replacing <project-path> with the path to your GitLab project.

Sourcegraph and Privacy

From Sourcegraph’s extension documentation which is the engine behind the native GitLab integration:

Sourcegraph integrations never send any logs, pings, usage statistics, or telemetry to Sourcegraph.com. They connect only to Sourcegraph.com as required to provide code intelligence or other functionality on public code. As a result, no private code, private repository names, usernames, or any other specific data is sent to Sourcegraph.com.
