Code Intelligence (FREE)

Introduced in GitLab 13.1.

Code Intelligence adds code navigation features common to interactive development environments (IDE), including:

Type signatures and symbol documentation.
Go-to definition.

Code Intelligence is built into GitLab and powered by LSIF (Language Server Index Format), a file format for precomputed code intelligence data.

NOTE: You can automate this feature in your applications by using Auto DevOps.

Configuration

Enable code intelligence for a project by adding a GitLab CI/CD job to the project's .gitlab-ci.yml which generates the LSIF artifact:

code_navigation:
  image: sourcegraph/lsif-go:v1
  allow_failure: true # recommended
  script:
    - lsif-go
  artifacts:
    reports:
      lsif: dump.lsif

The generated LSIF file size may be limited by the artifact application limits (ci_max_artifact_size_lsif), default to 100MB (configurable by an instance administrator).

After the job succeeds, code intelligence data can be viewed while browsing the code:

Find references

Introduced in GitLab 13.2 with a flag named code_navigation_references. Disabled by default.

Enabled on GitLab.com and self-managed in GitLab 13.3. Feature flag code_navigation_references removed.

To find where a particular object is being used, you can see links to specific lines of code under the References tab:

Language support

Generating an LSIF file requires a language server indexer implementation for the relevant language.

Language	Implementation
Go	`sourcegraph/lsif-go`
JavaScript	`sourcegraph/lsif-node`
TypeScript	`sourcegraph/lsif-node`
