# Code Intelligence
|
|
|
|
> [Introduced](https://gitlab.com/groups/gitlab-org/-/epics/1576) 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](https://lsif.dev/)
|
|
(Language Server Index Format), a file format for precomputed code
|
|
intelligence data.
|
|
|
|
## Configuration
|
|
|
|
Enable code intelligence for a project by adding a GitLab CI/CD job to the project's
|
|
`.gitlab-ci.yml` which will generate the LSIF artifact:
|
|
|
|
```yaml
|
|
code_navigation:
|
|
image: golang:1.14.0
|
|
allow_failure: true # recommended
|
|
script:
|
|
- go get github.com/sourcegraph/lsif-go/cmd/lsif-go
|
|
- lsif-go
|
|
artifacts:
|
|
reports:
|
|
lsif: dump.lsif
|
|
```
|
|
|
|
The generated LSIF file must be less than 170MiB.
|
|
|
|
After the job succeeds, code intelligence data can be viewed while browsing the code:
|
|

|
|
|
|
## Find references
|
|
|
|
> - [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/217392) in GitLab 13.2.
|
|
> - [Became enabled by default](https://gitlab.com/gitlab-org/gitlab/-/issues/225621) on GitLab 13.3.
|
|
> - It's enabled on GitLab.com.
|
|
|
|
To find where a particular object is being used, you can see links to specific lines of code
|
|
under the **References** tab:
|
|
|
|
![Find references](img/code_intelligence_find_references_v13_3.png)
|
|
|
|
### Enable or disable find references
|
|
|
|
Find references is under development but ready for production use.
|
|
It is deployed behind a feature flag that is **enabled by default**.
|
|
[GitLab administrators with access to the GitLab Rails console](../../administration/feature_flags.md)
|
|
can opt to disable it for your instance.
|
|
|
|
To disable it:
|
|
|
|
```ruby
|
|
Feature.disable(:code_navigation_references)
|
|
```
|
|
|
|
To enable it:
|
|
|
|
```ruby
|
|
Feature.enable(:code_navigation_references)
|
|
```
|
|
|
|
## Language support
|
|
|
|
Generating an LSIF file requires a language server indexer implementation for the
|
|
relevant language.
|
|
|
|
| Language | Implementation |
|
|
|---|---|
|
|
| Go | [sourcegraph/lsif-go](https://github.com/sourcegraph/lsif-go) |
|
|
| JavaScript | [sourcegraph/lsif-node](https://github.com/sourcegraph/lsif-node) |
|
|
| TypeScript | [sourcegraph/lsif-node](https://github.com/sourcegraph/lsif-node) |
|
|
|
|
View a complete list of [available LSIF indexers](https://lsif.dev/#implementations-server) on their website and
|
|
refer to their documentation to see how to generate an LSIF file for your specific language.
