Re: discover macro name

Hi

OK here are the details.

I use freemarker to render html in my Java web applications. Usually I 
will have macros to render some html snippets such as search form, 
search result, login form etc because I reuse them in many projects and 
they feature the exact same html. The graphic designers (the people who 
initially do the static html layout) want to be able to see where these 
snippets start and end, in the final rendered product (when running on 
"debug" mode), in order to maintain/debug html rendering issues.

I've got around 30 of those macros.

So, instead of doing the following:
<#macro renderSearchForm>
  <!-- renderSearchForm starts -->
  <p>bla bla bla...</p>
  <!-- renderSearchForm ends -->
</#macro>

<#macro renderLoginForm>
  <!-- renderLoginForm starts -->
  <p>bla bla bla...</p>
  <!-- renderLoginForm ends -->
</#macro>


I'd like to be able to do something like:
<#macro renderSearchForm>
  <!-- ${currentMacroname} starts -->
  <p>bla bla bla...</p>
  <!-- ${currentMacroname} ends -->
</#macro>

So I don't have to maintain too much stuff, especially in case of macro 
name refactorings.

This will eventually lead me to a more generic macro such as:
<#macro renderSearchForm>
  <@commentWrap currentMacroname>
     <p>bla bla bla...</p>
  </@commentWrap>
</#macro>

Which will be a macro wrapping the nested html (using <#nested /> ) with 
the appropriate html comments.

thanks,
Ioannis
