The virtual field's render method reads the value from the actual field you're interested in and renders it differently. The problem with virtual fields is that I think they're hard to test for in epxml (and possibly also with is_set).<div class=""><br class=""></div><div class="">You can see an example from the tweepository package here:</div><div class=""><br class=""></div><div class=""><span class="Apple-tab-span" style="white-space:pre"> </span><a href="https://github.com/gobfrey/tweepository/blob/master/cfg/cfg.d/z_tweepository_libs.pl#L314" class="">https://github.com/gobfrey/tweepository/blob/master/cfg/cfg.d/z_tweepository_libs.pl#L314</a> (field definition)</div><div class=""><span class="Apple-tab-span" style="white-space:pre"> </span><a href="https://github.com/gobfrey/tweepository/blob/master/cfg/cfg.d/z_tweepository_libs.pl#L1710" class="">https://github.com/gobfrey/tweepository/blob/master/cfg/cfg.d/z_tweepository_libs.pl#L1710</a> (render method)</div><div class=""><br class=""><div class=""><div class=""><div class="">
