LinuxQuestions.org - problems iterating in RUBY while extracting info from YAML, Pls help!

Hi all,
I am stuck with a ruby script that extracts detials from yaml file and processes accrodingly.
the yaml file

Code:



confivnic:

  device:

    vnic1:

      policy:

      - L2

      mode: active

    vnic2:

      policy:

      - L3

      - L4

      mode: active

  type: aggr



notsoconfi:

  device:

    vnic9:

      policy:

      - L2

      - L3

      mode: "off"

    vnic3:

      policy:

      - L2

      - L3

      mode: active

    vnic6:

      policy:

      - L3

      - L2

      mode: active

  type: aggr

the ruby script

Code:

require 'yaml'

yaml = YAML::load(File.open("testyaml.yaml"))



yaml.each do |name, option|

if option['type'] == "aggr"

names = Array.new

names.push name

while names.size != 0

key = yaml.keys.first

tpl = "dladm create-{{{type}}} {{{sets}}} {{{cmd}}}"

tpl.gsub! '{{{type}}}', yaml[key]['type']

tpl.gsub! '{{{cmd}}}',  key

sets = ''

set_tpl = '-l {{{key}}} -L={{{mode}}} -P={{{policy}}} '

yaml[key]['device'].each do |device|

  set = set_tpl.dup

  set.gsub! '{{{key}}}',    device[0]

  set.gsub! '{{{mode}}}',  device[1]['mode']

  set.gsub! '{{{policy}}}', device[1]['policy'].join(',')

  sets << set

end

names.pop

end

tpl.gsub! '{{{sets}}}', sets

puts tpl.gsub(/\s+/,' ')

end

end

The o/p i get is like this

Code:

dladm create-aggr -l vnic9 -L=off -P=L2,L3 -l vnic3 -L=active -P=L2,L3 -l vnic6 -L=active -P=L3,L2 notsoconfi

dladm create-aggr -l vnic9 -L=off -P=L2,L3 -l vnic3 -L=active -P=L2,L3 -l vnic6 -L=active -P=L3,L2 notsoconfi

but the yaml file has 2 names ,"confivnic" and "notsoconfi"
This was written originally for just one module but for obvious reasons we had to change it. I tried all i knew but really not finding a way out.
The things that i feel are creating errors are yaml.keys.first
or the way iteration is done.

The o/p i want is similar to the shown one but instead of repeating the same one twice i want the other one to be displayed as well with the necessary changes.

Pls help
