[stringtemplate-interest] More Issues with Collections

[Kenny Cockburn]

Hi,

I thave found what I think are problems with IEnumerator

1. IEnumerator does not call rest() after the collection has finished 
the iteration
2.IEnumerator First() works but rest() call misses a row in the collection


here is the code to show both problems :

        static void Main()
        {

            string simpleIfTest = @"
group TestIEnum ;

Action(Arg) ::=<<
iterate 1
$Arg:{X=$it$ # }$
----                                                    /
iterate 2
$Arg:{X=$it$ # }$
----
 >>
ActionFirstRest(Arg) ::=<<

First Rest Tests
iterate 1
First
$first(Arg):{X=$it$ # }$
Rest
$rest(Arg):{X=$it$ # }$
----                                                    /
iterate 2
First
$first(Arg):{X=$it$ # }$
Rest
$rest(Arg):{X=$it$ # }$
----

";
            StringTemplateGroup stg = new StringTemplateGroup(new 
StringReader(simpleIfTest), typeof(DefaultTemplateLexer));
            int[] myIntArray = new int[5] { 1, 2, 3, 4, 5 };
           
            System.Console.WriteLine("Run Test with simple Array");
            StringTemplate sta3 = stg.GetInstanceOf("Action");
            sta3.SetAttribute("Arg", myIntArray);
            System.Console.WriteLine(sta3.ToString());


            System.Console.WriteLine("Run Test with type only supporting 
IEnumerator");
            sta3 = stg.GetInstanceOf("Action");
            sta3.SetAttribute("Arg", myIntArray.GetEnumerator() );
            System.Console.WriteLine(sta3.ToString());

            System.Console.WriteLine("Run First Rest Test with simple 
Array");
            sta3 = stg.GetInstanceOf("ActionFirstRest");
            sta3.SetAttribute("Arg", myIntArray);
            System.Console.WriteLine(sta3.ToString());


            System.Console.WriteLine("Run First Rest Test with type only 
supporting IEnumerator");
            sta3 = stg.GetInstanceOf("ActionFirstRest");
            sta3.SetAttribute("Arg", myIntArray.GetEnumerator());
            System.Console.WriteLine(sta3.ToString());

        
        }
