Ruby

A systems integration framework, built to bring the benefits of configuration management to your entire infrastructure.

Chef::Blacklist.filter

filter takes two arguments - the data you want to filter, and a blacklisted array
of keys you want discluded. You can capture a subtree of the data to filter by
providing a "/"-delimited string of keys. If some key includes "/"-characters,
you must provide an array of keys instead.

Blacklist.filter(
  { "filesystem" => {
      "/dev/disk" => {
        "size" => "10mb"
      },
      "map - autohome" => {
        "size" => "10mb"
      }
    },
    "network" => {
      "interfaces" => {
        "eth0" => {...},
        "eth1" => {...}
      }
    }
  },
  ["network/interfaces/eth0", ["filesystem", "/dev/disk"]])
will exclude the eth0 and /dev/disk subtrees.
