Hi folks -- is there a hook to filter or process the ticket
history texts
(email bodies) when they're displayed? We'd like to turn certain
pieces of

You should be able to use the ModifyDisplay callback in
Tickets/Elements/ShowTransaction to do this.
Thanks, Kevin -- that looks like exactly what I need. I'll try
it. Does
anyone have a sample Callbacks/*/Elements/Ticket/ShowTransaction/
ModifyDisplay
callback? I don't really understand the calling convention, i.e.
what are the
args and what I'm supposed to return. Should I write a function,
or is it
just bare Mason/perl code? What are %INIT% and %ARGS% (I see those
in some
other callbacks)? Where do I get the actual ticket text (message
body)?
(I looked at the rt wiki page "CustomizingWithCallbacks" and it
explains the
proper file/dir to put the callback in, but doesn't say what it
should look like.)
The RTFM and RTIR packages on http://download.bestpractical.com/pub/
rt/devel/ make
extensive use of callbacks. I'm not sure if they use that specific
callback, but
you should be able to understand the technique from them.
