Composer Debug Flags
You can trace the execution of the publishing framework by entering the following three commands on the Arbortext Editor or Arbortext Publishing Engine Interactive command line:
source compose.acl;
$compose::debug=2;
$compose::verbose=1;
You can skip the initial source command if you've already performed a publishing operation.
Setting these two ACL global variables result in:
The parameters debug and verbose will be passed to the content pipelines that run for future publishing operations. Some pipeline filters will heed these values and write additional information to the event log.
The publishing framework will display dialog boxes showing the current values of its parameter array as it does its work. As each dialog box is displayed, execution will halt until you press the OK button.
If you don't want to dismiss each of the dialog boxes for each publishing operation, but you still want to inspect the results from the parameter arrays, you can set compose::debug to 1. The publishing framework will not display any dialog boxes, but it will place an entry in the event log for each point where a dialog box would have been displayed.
