But that depends what your area of interest is. Completers are small functions that are called from virsh whenever user started typing something and hit TAB TAB. Their purpose is to offer list of strings that suit entered input. If there is only one item on the list then it's entered in automatically. For instance: virsh # dom<TAB><TAB> domblkerror domblkstat domcontrol domfsinfo .. virsh # start --domain <TAB><TAB> fedora fedora.i686 freebsd gentoo ... (this will vary depending on your domains intalled) The framework is merged, the only thing that is missing are these small functions (called callbacks) that are called by the framework at appropriate times. For instance: virshDomainNameCompleter() is called whenever a domain name is to be completed (just like we've seen for virsh start example). I find writing completers to be a nice introduction into libvirt because they use our public APIs therefore one gets sense of libvirt. But feel free to chose anything, I'm just putting it out there.
