Getting Started

How do I build it?

See the README.

Are there examples using hawkey?

Yes, look at:

• unit tests
• The Hawkey Testing Hack
• a more complex example is DNF, the Yum fork using hawkey for backend.

Using Hawkey

How do I obtain the repo metadata files to feed to Hawkey?

It is entirely up to you. Hawkey does not provide any means to do this automatically, for instance from your /etc/yum.repos.d configuration. Use or build tools to do that. For instance, both Yum and DNF deals with the same problem and inside they employ urlgrabber to fetch the files. A general solution if you work in C is for instance libcurl. If you are building a nice downloading library that integrates well with hawkey, let us know.

Why is a tool to do the downloads not integrated into Hawkey?

Because downloading things from remote servers is a differnt domain full of its own complexities like HTTPS, parallel downloads, error handling and error recovery to name a few. Downloading is a concern that can be naturally separated from other parts of package metadata managing.
