The vshReadlineParse() function is called whenever user hits <TAB><TAB>. If there is no command (or a partially written one), then a list of possible commands is printed to the user. But, if there is a command then its --options are generated. But obviously, we can not generate --options if there already is an --option that's expecting a value. For instance, consider: virsh # start --domain <TAB><TAB> In this case we want to call completer for --domain option, but that's a different story. Anyway, the way that we currently check whether --options list should be generated is checking the type of the last --option. If it isn't DATA, STRING, INT, or ARGV (all these expect a value), then we can generate --option list. Well, writing the condition this way is needlessly verbose and also prone to errors (see d9a320bf97 for example). We know that boolean type does not require a value. This leaves us with the only type that was not mentioned yet - VSH_OT_ALIAS. This is a special type for backwards compatibility and it refers to another --option which can be just any type.

Libvirt API for virtualization
==============================
Libvirt provides a portable, long term stable C API for managing the
virtualization technologies provided by many operating systems. It
includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware
vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER
Hypervisor.
For some of these hypervisors, it provides a stateful management
daemon which runs on the virtualization host allowing access to the
API both by non-privileged local users and remote users.
Layered packages provide bindings of the libvirt C API into other
languages including Python, Perl, PHP, Go, Java, OCaml, as well as
mappings into object systems such as GObject, CIM and SNMP.
