Ant 1.3 provides for
a mapper that allows the definition of mapping between a
fileset and derived
files for testing "uptodate", including a "merge" mapping
that goes from a set
of giles to a single file (such as a .jar or .zip).
Several kinds of
build activities go from a single file to many files. The one
I
am encountering all
the time is code generation for CORBA, where a single
.idl file is
converted into many .java files. I'd probably handle this
as
<uptodate
property="idlgen.uptodate">
<srcfiles dir="${idl.dir}" name="some.idl" />
<targetfiles dir="${java.out.dir}/some" />
</uptodate>
Then
srcfiles AND targetfiles are FileSets and only if all targets
are
more recent
than all sources is the target up to date. In some
cases
it is common to
idlgenerate a set of idl files into many java files in one operation,
so often srcfiles
will actually be in the form "*.idl" or some more general FileSet.
This also
suggests that mapping might be an element of a fileset,
somehow.
<fileset
id=obj.files>
<mapping type="glob" from="*.c" to="*.o" />
<fileset refid=c.files />
</fileset>
sorry for the
long append...
