Hi all,
I'm looking to filter a macrodef element before it gets interpreted so as to change it's behavior. Here's an example of what I'm
talking about:
<target name="myentrypoint">
...
<mymacro>
<%{mytask} %{myattribute}="%{myvalue}"/>
%{myblockofcode}
</mymacro>
...
</target>
In other words, I want the definition of mymacro to do *token substitution *on the (implicit) element body and then have that
changed body executed. (The token substitution algorithm, in my case, is not a simple replacement procedure but requires some more
complex processing, in case that matters to this question.)
Here are my limitations:
1. My target is being called by some other Ant code. I do not have any control of what happens before I'm called, nor can I change
how Ant was invoked or do any compilation.
2. Once in my target, I can use Groovy scriptdefs, Ant-Contrib, and anything
that comes with Ant 1.7.
Can anyone suggest how this might be done? I did read "Developing with Apache Ant, Writing Your Own Task
<http://ant.apache.org/manual/develop.html>," but I'm not sure if this helps considering what I have available to me. I'm hoping
that since I have Groovy (essentially, Java), that something might still be possible.
Any ideas?
Many thanks,
