- not sure if it's fine of group name contains space, Because it need
user to quote the whole group name when input. Probly we need some
abstract group names for user.
In general, this all looks like a good start. :)
The quoted group names bit though... yeah, it's not good for usability. :/
Thinking here, that we should aim for something where a person can type in
one simple key word (preferably tab completion works on it too).
ie:
virsh # help filter
(outputs Network Filter help info)
Actually, the tab completion isn't all that required. If it's an easy thing to add, then
"might as well", but if it's a bunch of coding then it's probably not worth it. :)
Currently virsh just tab completes the first command and options of
that command.. e.g.
"virsh # migrate --"
"virsh # help some_command" doesn't support tab completion for
"some_command".
think it's no need to add it, it's only helpful for "help" command,
and yes, a bunch of coding, and also it will make "help" confused
if we use the short key word for groups, e.g. suppose we use "domain"
as the key word for "domain management" group. then what should
"virsh # help dom" behave? :-)
With the group key words, they could be listed in the help text itself, something
like:
virsh # help
...
Network Filter (help keyword 'filter')
nwfilter-define define or update a network filter from an XML file
nwfilter-undefine undefine a network filter
nwfilter-dumpxml network filter information in XML
nwfilter-list list network filters
nwfilter-edit edit XML configuration for a network filter
...
It might make the help output look a bit messy, but its nice and clear and puts
info in front of people at the point they need it.
As a starting point, if the above seems reasonable to you, how's this for keywords?
"Domain Management" -> domain
"Domain Monitoring" -> monitor
"Storage Pool" -> pool
"Storage Volume" -> volume
"Networking" -> network
"Node Device" -> device
nodedev instead?
"Interface" -> interface
"Network Filter" -> filter
"Secret" -> secret
"Snapshot" -> snapshot
"Host and Hypervisor" -> host
"Virsh Itself" -> virsh
I've thrown the keywords above onto the wiki page, in case it helps:
http://wiki.libvirt.org/page/VirshHelpV2
it's the guide, thanks :-)
