... or you can modify the array

node.normal_attrs[:packages_install_specific].reject! {|p| p[0] == "libicu-devel" }

--max

What if you make it a hash instead of a list?

set[:packages_install_specific] = {
  "js" => "1.70-8",
  "icu" => "3.6-5.16.1",
...
}

Then you can do, eg, node.normal_attrs[:packages_install_specific].delete("js")

I'm probably not using the right terms, but lets' say I have the following:

set[:packages_install_specific] = [

  ["js","1.70-8"],

  ["icu","3.6-5.16.1"],

  ["libicu","3.6-5.16.1"],

  ["libicu-devel","3.6-5.16.1"]

]

The attrs looks like:

{

    "normal": {

     "packages_install_specific": [

        [

          "js",

          "1.70-8"

        ],

        [

          "icu",

          "3.6-5.16.1"

        ],

        [

          "libicu",

          "3.6-5.16.1"

        ],

        [

          "libicu-devel",

          "3.6-5.16.1"

        ]

     ]

...

Is it possible to delete the tuple   ["libicu-devel","3.6-5.16.1"] programmatically in a recipe? I've tried using:

node.normal_attrs[:packages_install_specific].delete(:libicu-devel) rescue nil

But I probably can't refer to it as a key...Can someone shed some light on this? If someone can forward me to some docs I'd greatly appreciate it. Running 0.9.x (8 I believe), thanks in advance!
