It helps you search, cross-reference and navigate your source tree. It can understand various program file formats and version control histories of many source code management systems. Official page of the project is on: <https://oracle.github.io/opengrok/> ## 2. Installation See https://github.com/oracle/opengrok/wiki/How-to-setup-OpenGrok ### 2. 1. Updating OpenGrok uses [semantic versioning](https://semver.org/) and the version components further indicate more details about updating to newer version. The version scheme is *major.minor.micro* and change in any component is interpreted as: - major - major backwards incompatible update, will require full reindex as well as configuration changes - minor - full clean reindex of your repositories is needed (e. g. index format has changed) - micro - redeploy web application Generally it is possible to go backward only within the micro version. ## 3. Information for developers See https://github.com/oracle/opengrok/wiki/Developer-intro and https://github.com/oracle/opengrok/wiki/Developers ## 4. Authors The project has been originally conceived in [Sun Microsystems](https://en.wikipedia.org/wiki/Sun_Microsystems) by Chandan B.N. For full list of contributors see https://github.com/oracle/opengrok/graphs/contributors ## 5. Contact us Use the [GitHub Discussions](https://github.com/oracle/opengrok/discussions). ## 6. Run as container You can run OpenGrok as a Docker container as described [here](docker/README.md). ## Contributing This project welcomes contributions from the community.
