Hammer is a generic clamp-based CLI framework. Hammer-cli provides just the core functionality. The core is extensible using plugins that contain application-specific commands.

This architecture allows for easy customization according to your application. Nearly any Ruby script can be turned into a Hammer command, so the possibilities are endless. You also can easily add custom commands for your specific use, such as bulk actions or admin tasks.

Available plugins are listed on the Foreman's wiki.

Check out the release notes to see what's new in the latest version.

We build rpms, debs and gems. Alternatively you can install hammer from a git checkout. See our installation and configuration instuctions.

If one of hammer commands doesn't work as you would expect, you can run hammer -d ... to get full debug output from the loggers. It should give you an idea what went wrong.

If you have questions, don't hesitate to contact us on [email protected] or the Freenode#theforeman IRC channel.

If you're interested in hammer and want to develop some plugins for Foreman or use it as a base for your own CLI, read the developer docs.
