Description

It is not possible to parse complex parameters of type list. E.g.

hammer os create --architectures amd64,i386 --description "Windows 7 EN (2019-01)" --major 6 --minor 1.7601 --family Windows --partition-tables Empty --password-hash SHA256 --provisioning-templates winpe_clone,winpe_finish,winpe_pxelinux_boot_clone,winpe_unattend_template --name Windows7EM2019-01 --os-parameters-attributes="test=1,other=2" 

Error: ApipieBindings::InvalidArgumentTypesError: operatingsystem[os_parameters_attributes][0] - Hash was expected, operatingsystem[os_parameters_attributes][1] - Hash was expected

The field is defined as a list of hashes in the API

          param :os_parameters_attributes, Array, :desc => N_("Array of parameters") do
            param :name, String, :desc => N_("Name of the parameter"), :required => true
            param :value, String, :desc => N_("Parameter value"), :required => true
          end

At the very least we should allow to use JSON to provide the value

--os-parameters-attributes="[{\"name\":\"test\", \"value\":1}]"

That possibility should be mentioned in the help. We may be able to construct and example based on the param description.

 --os-parameters-attributes OS_PARAMETERS_ATTRIBUTES   Array of parameters
                                                       Comma separated list of values. Values containing comma should be quoted or escaped with backslash

Is really hard to use without consulting the API docs.

We may think of something like following for the List normalizer to allow the JSON input.

         def format(val)
-          (val.is_a?(String) && !val.empty?) ? HammerCLI::CSVParser.new.parse(val) : []
+          return [] unless val.is_a?(String) && !val.empty?
+          begin
+              formatter = JSONInput.new
+              formatter.format(val)
+          rescue ArgumentError
+            HammerCLI::CSVParser.new.parse(val)
+          end
         end
