It might be nice to change some of the devstack usage into that. It
would help spread the word about it, and be a bit easier to understand.

It may in places, but it turns out the 'value' formatter is most useful,
especially in the get_or_create_* functions where you really only need a
single value, avoids an eval or extra subshell.

group_id=$(
# Creates new group with --or-show
openstack --os-token=$OS_TOKEN --os-url=$os_url \
--os-identity-api-version=3 group create $1 \
--domain $2 --description "$desc" --or-show \
-f value -c id
)
echo $group_id

Devstack should also look at using the shell output formatter,
especially for show commands. Combining that formatter with eval means
no parsing in a lot of cases.

I loved reading this email as much as zigo loves csv output, great feedback
is an amazing motivator!

And don't worry, the csv output was never going away :)

Erm, yeah, I hear your pain with processing output with awk.

Having the option to output CSV is cool :-).
Thanks for sharing.
