[chef] RE: Is a Chef Resource that returns a boolean value?

[Adam Edwards < >]

Correction: actually, in the example below, the workaround must be inverted, so a "!” needs to be added:

 

    powershell –command "exit [int32](!(get-executionpolicy) -eq 'remotesigned'))"

David, I have a branch in progress that adds this feature to powershell_script (if I understand you correctly). See the doc at https://github.com/opscode/chef-rfc/blob/adamed/resource-guard/rfc0001-resource-guard.md -- it has a link to a branch.

 

Is this the behavior you'd like to see?

 

    # What if guards evaluated powershell script code that powershell

    # evaluates as a boolean type as the actual boolean value of the guard

    # itself? You can avoid extra script code to translate the boolean into

    # a process exit code that results in the right true / false behavior

    # for the guard

    powershell_script "set execution policy" do

      code "set-executionpolicy remotesigned"

      not_if "(get-executionpolicy) -eq 'remotesigned'" # Like I barely left Ruby -- wow!

    end

 

The current workaround for the example above is to use an _expression_ like

  powershell –command "exit [int32](get-executionpolicy) -eq 'remotesigned')"

 

in the not_if above. It basically forces the script to convert a Boolean data type to an integer that is then returned as the process exit code, which is interpreted by Chef as a Boolean value.

I work with Chef on Windows node and find myself writing a lot of Chef guards for the powershell_script resource.  I was wondering if there was a Chef resource that returned a boolean value that I could use here.

Thank you,

David Williams
