How to uppercase entire variable in Resharper Template?

Question

I have a situation where I want the variable to be capitalized for documentation eg
(trivalized for example)

///AT+$COMMAND$

void At$COMMAND$()
{
}

So I want the user of the template to type in something like "Blah" and that gets used in the method name, but the documentation part gets changed to "BLAH".

eg

///AT+BLAH
void AtBlah()
{
}

Can I do this? I see in the macros I can capitalize the first letter, but I'd like the whole word capitalized. Is it possible to create custom macros?

They just updated documentation to meet changes in macros in Resharper 8. You can check it at http://confluence.jetbrains.com/display/NETCOM/4.04+Live+Template+Macros+%28R8%29

With the new docs it is quite easy, my implementation goes here:

using System.Collections.Generic;
using System.Linq;
using System.Runtime.InteropServices;
using JetBrains.DocumentModel;
using JetBrains.ReSharper.Feature.Services.LiveTemplates.Macros;
using JetBrains.ReSharper.Feature.Services.LiveTemplates.Hotspots;

namespace ReSharperPlugin
{
    [MacroDefinition("LiveTemplatesMacro.CapitalizeVariable", // macro name should be unique among all other macros, it's recommended to prefix it with your plugin name to achieve that
    ShortDescription = "Capitalizes variable {0:list}", // description of the macro to be shown in the list of macros
    LongDescription = "Capitalize full name of variable" // long description of the macro to be shown in the area below the list
    )]
    public class CapitalizeVariableMacro : IMacroDefinition
    {
        public string GetPlaceholder(IDocument document, IEnumerable<IMacroParameterValue> parameters)
        {
            return "A";
        }

        public ParameterInfo[] Parameters
        {
            get { return new[] {new ParameterInfo(ParameterType.VariableReference)}; }
        }
    }

    [MacroImplementation(Definition = typeof(CapitalizeVariableMacro))]
    public class CapitalizeVariableMacroImpl : SimpleMacroImplementation
    {
        private readonly IMacroParameterValueNew _parameter;

        public CapitalizeVariableMacroImpl([Optional] MacroParameterValueCollection parameters)
        {
            _parameter = parameters.OptionalFirstOrDefault();
        }

        public override string EvaluateQuickResult(IHotspotContext context)
        {
            return _parameter == null ? null : _parameter.GetValue().ToUpperInvariant();
        }
    }
}
