I second this wish. I'd like to see fileset have a mapper element
which mapped includes, excludes and/or refid'd filesets.
Consider a build that puts files *and their MD5 checksums* into a ZIP.
It creates and populates a fileset which is passed to the checksum
task. The same fileset is then passed to the zip task. What about the
*.MD5 files? The zip task should receive two filesets: the source
fileset; and the source fileset globbed from "*" to "*.MD5".
My solution is to populate the second set in a Jython script:
---- mappedfileset.py ----
def getRef(prop):
return project.getReferences().get(prop)
inputfileset = getRef(map_inputfileset)
outputfileset = getRef(map_outputfileset)
mapper = getRef(map_mapper).getImplementation()
scanner = inputfileset.getDirectoryScanner(project)
scanner.scan()
for name in scanner.getIncludedFiles():
mappedNames = mapper.mapFileName(name)
if mappedNames is not None:
for n in mappedNames: outputfileset.createInclude().setName(n)
outputfileset.getDirectoryScanner(project).scan()
------------
And to have this in my build:
<fileset id="images.fileset" dir="${images.dir}">
... includes / excludes ...
</fileset>
<mapper type="glob" from="*" to="*.MD5" id="md5-glob"/>
<fileset id="checksum.fileset" dir="${images.dir}"/>
<property name="map_inputfileset" value="images.fileset"/>
<property name="map_outputfileset" value="checksum.fileset"/>
<property name="map_mapper" value="md5-glob"/>
<script language="jpython"
src="${script-source.dir}/mappedFileSet.py"/>
...
<zip destfile="${image-zip.location}" compress="no">
<fileset refid="images.fileset"/>
<fileset refid="checksum.fileset"/>
</zip>

I guess I'd like to create a new fileset from an old one. I'd like to
use
foreach on the new fileset (or the 'right' side of the map, no longer
care about
the left). I don't think the perforce tasks support wildcards, so I
thought I
could iterate through a fileset, but I need to flatten the filenames.

No. That doesn't really make sense in a general sense, at least to me.
A fileset is a set of existing files, so mapping them doesn't
preserve
that meaning.
Mappers are associated directly with several tasks, such as <copy>.
What do you have in mind specifically?
