Add an ant target at the end of an existing transform type

[gdelory]

Hi all,

I'm trying to run an Ant target at the end of the html5 transform. It doesn't seem to be an extension point at the end of the target, and the depend.preprocess.post extension point is too early for me (I'm trying to move files around in the output folder at the end of the transform, to end up only with in-scope content, as a temporary work-around for this discussion).

I know I can easily create my own new transform type and depends on the html5 transform then my new ant target doing the deleting/moving of the files, but the issue it that we already have thousands of transforms/users using the html5 transform and we would rather avoid changing the name of the transform.

The best I found so far would be to import my ant file with ant.import (same as for a new transform anyway), and override the dita2html5 target. The tricky part was to reference the original dita2html5 target, since my new target has the same name. I managed by prefixing the original target with the project name though:

<target name="dita2html5"
  depends="dita2html5.dita2html5,
  no-outer-content.move"/>

My question is: Is there a better way to run an Ant target at the end of an existing transform, like an extension point I missed, or something else?

Thank you

Looking at this template:

DITA-OT/plugins/org.dita.base/build_template.xml

<target name="init">
<dita-ot-fail id="DOTA001F">
  <condition>
    <and>
      <dita:extension id="dita.conductor.transtype.check" behavior="org.dita.dost.platform.CheckTranstypeAction"
                      property="transtype"/>
    </and>
  </condition>
  <param name="1" value="${transtype}"/>
</dita-ot-fail>
<property name="clean.temp" value="yes"/>
<property name="build-step.clean-temp" value="${clean.temp}"/>
<preprocess-skip-init name="clean-temp" step="clean-temp"/>
<antcall inheritRefs="true">
  <target name="dita2${transtype}"/>
  <target name="clean-temp"/>
</antcall>

The "clean-temp" seems to be done last.
And looking at the definition of the "clean-temp" target in "DITA-OT/plugins/org.dita.base/build_preprocess_template.xml" it seems to depend on this extension point "depend.preprocess.clean-temp.pre".

Thanks @raducoravu that's an excellent idea! I actually initially saw that clean-temp was run after the main dita2${transtype} target, but didn't think at all to go check if it had an extension point 😄

The good news is that even when you have -Dclean.temp=no, the depend.preprocess.clean-temp.pre extension point seems to run, I just tried to make sure. We don't really use it on production obviously, but I use it a lot when developing so it's nice that it still runs even when the temp clean up is disabled.

I like it more that overwriting the dita2html5 target which feels a bit hacky, so I probably will go with your solution. Thanks again.
