Subject AW: Search for folders and access them
Date Wed, 05 Aug 2009 08:44:51 GMT
In Ant you usually have ONE action which processes a bunch of resources.
E.g. instead of iterating over a fileset and copying each individual file you
have 
  <copy todir=""><fileset.../></copy>

There are many tasks which support filesets, paths or resource collections.

A resource collection (as the most abstract type of these resources) returns resources
after a check by a "selector". 

Example: <fileset dir="."><filename regex="foo.*"/></fileset>
The file scanner scans the base directory recursively. Each file is passed to the <filename>
selector
which "selects" the file if the name matches the given regular expression.

So selecting certain files is easy.
Selecting directories which contains a special "marker file" is more tricky...
  <!-- The dirset which contains only marked directories -->
  <dirset id="dirset" dir="${workingdir}">
     <present targetdir="${workingdir}">
          <mapper type="glob" from="*" to="*/${markerfile}" />
     </present>
  </dirset>
or
  <!-- The dirset which contains only marked directories -->
  <dirset id="dirset" dir="${workingdir}">
      <scriptselector language="javascript">
          if (file.isDirectory()) {
              markerName = project.getProperty("markerfile");
              markerFile = new java.io.File(file, markerName);
              self.setSelected( markerFile.exists() );
          }
      </scriptselector>
  </dirset>
