Ian, Gert, how about this:
http://www.mail-archive.com/[EMAIL PROTECTED]/msg03737.html
Some time ago I posted an implementation of "fileset" family of functions
that works with named filesets. Can we include it in NAnt?
 

Thats right - I remembered that. I actually thought it had already been 
added and I went looking for it in the source :) .  I think its a good 
addition. Re-reading that thread it looks like we all agreed in 
principle just that no one got around to adding it. If put in fileset 
functions do we do it now or post 0.85 ?

Hi, I'm migrating an ant based build file to nant. One of the things I
need to migrate is the invocation of the java vm passing a classpath
as an argument, ant allows one to do it like this:
      <java classname="junit.textui.TestRunner">
          <classpath>
                  <fileset dir="jsunit/lib">
                      <include name="*.jar"/>
                  </fileset>
                  <fileset dir="jsunit/bin">
                      <include name="jsunit.jar"/>
                  </fileset>
          </classpath>
          <arg value="net.jsunit.StandaloneTest" />
      </java>
My question is how can I achieve the same effect with the exec task?
     <exec program="java">
          <!-- is there any way to get a filelist from a fileset and
put it here? -->
        <arg value="-cp ?????" />
        <arg value="junit.textui.TestRunner" />
        <arg value="net.jsunit.StandaloneTest" />
     </exec>
     

Right now there is no support for this in the exec task directly
although now that I think about it it seems reasonable to have a fileset
child element on <exec> that just passes the files a list of quoted
strings at the end of the arg list - although not all commandline apps
will want it formatted that way.
Heres how you could do it using the <script> task:
<project name="test" >
<script language="C#">
  <imports>
      <import name="NAnt.Core.Types" />
  </imports>
           <code><![CDATA[
           [Function("fileset-tolist")]
           public string FileSetToList( string fset ) {
               FileSet fs = (FileSet)Project.DataTypeReferences[fset];
               StringBuilder sb = new StringBuilder();
               foreach(string file in fs.FileNames ){
                   sb.AppendFormat(" \"{0}\" ", file );
               }
               return sb.ToString();
           }
           ]]></code>
  </script>
<fileset id="foo">
   <include name="*.jar"/>
</fileset>
  <exec program="java">
        <arg value="${script::fileset-tolist('foo')}" />
   </exec>
</project>
   

I'm also considering implementing a java task just for the fun of it
but I'd like to keep my life simple :)
     

A java task would be kinda cool - somthing that works ikvm would be
   

awesome.
