OpenGrok

A fast and usable source code search and cross-reference engine by Oracle, written in Java. It helps you search, cross-reference, and navigate your source tree with support for many programming languages and version control systems.

What You Can Do After Deployment

1. Access the web UI at your assigned domain
2. Add source code by mounting repositories into the /opengrok/src directory
3. Search code using full-text search, definition search, symbol search, path search, and history search
4. Navigate cross-references by clicking on symbols to jump to definitions and usages
5. Browse repositories through the built-in file browser with syntax highlighting
6. Trigger re-indexing via the REST API at port 5000

Key Features

• Full-text search across large codebases
• Cross-reference navigation for symbols, definitions, and usages
• Syntax highlighting for 60+ programming languages
• Version control integration (Git, SVN, Mercurial, Bazaar, and more)
• Automatic periodic re-indexing
• REST API for administration

Getting Started

Place your source code repositories as subdirectories under /opengrok/src. The indexer will automatically scan and index them at regular intervals.
