FAQPage Schema

How do I perform semantic code analysis to find usages of a function across my codebase?▼

Semantic code analysis locates all usages of a function by indexing your repository with the GitLab Knowledge Graph, enabling accurate find-usages queries across supported languages. You can then navigate directly to symbol definitions and trace references.

Can I use this for go-to-definition navigation in Python and TypeScript?▼

Yes, go-to-definition navigation is supported for Python and TypeScript/JavaScript, alongside Ruby, Java, and Kotlin. The semantic analysis engine parses your Git repository to build the necessary code navigation graph.

What is the best way to analyze the impact of code changes before refactoring?▼

Impact analysis identifies all affected usages of modified symbols before refactoring by querying the GitLab Knowledge Graph. This semantic approach maps dependencies across the codebase to prevent breaking changes.

Does architecture visualization work with Java and Kotlin codebases?▼

Architecture visualization is supported for Java and Kotlin codebases, generating diagrams from the semantic analysis of your Git repository. It maps structural dependencies to clarify complex software architecture.

Do I need a Git repository to run semantic code analysis?▼

Yes, a Git repository is required to run semantic code analysis and build the GitLab Knowledge Graph. The indexing process relies on the repository structure to accurately parse definitions and map usages.
