Re: [openstack-dev] [openstackclient] Use and practices of --format shell for defining individual variables
Thanks Doug,
I knew there would be a more definitive and simple use.
eval is that way!

Hi list,
I came across the following neutron client specific syntax and decided to
see if I could reproduce using the openstack client and it's flexible
formatting capabilities
$ NIC_ID1=$(neutron net-show public | awk '/ id /{print $4}')
$ echo $NIC_ID1
210d976e-16a3-42dc-ac31-f01810dbd297
I can get similar syntax (unfortunately lowercase variable name only)
with:
NOTE: It may be nice to be able to pass an option to UPPERCASE all shell
variables names.
$ openstack network show public -c id --format shell --prefix nic_
nic_id=210d976e-16a3-42dc-ac31-f01810dbd297
However to use this I effectively have to place in a file and source that
file to expose this variable to my current running shell.
Reproducing the same syntax does not work obviously.
It's actually meant to be used with an eval statement:
$ eval $(openstack network show public -c id --format shell --prefix nic_)
$ echo $nic_id

The remaining networking functions use the Compute API for nova-net. We have not really mapped the requried commands to OSC form yet, that is going to be the hardest part of implementing them. They need to be consistent with the rest of OSC. Some of what you mentioned is common to all OSC commands, like the output formatting is all done with cliff. I don't know how much of that would be common to neutronclient too since it also uses cliff, but sometimes in a different way. dt -- Dean Troyer dtro...@gmail.com __ OpenStack Development Mailing List (not for usage questions) Unsubscribe: openstack-dev-requ...@lists.openstack.org?subject:unsubscribe http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
