Hi Steve,
Sorry to arrive in the discussion at such a late time
but I had other things that needed attention. In the
meantime, you've received a whole range of interesting
answers.
All in all, it is perfectly possible to export a
RunRev stack to XML and bring it back afterwards. And
I'm sure that Geoff Canyon's MCRipper is an excellent
place to start.
You can iterate over the substacks and their cards and
so forth, and thus export all the information of all
the controls. This should work fine if you
base64Encode() the binary bits such as imageData.
We know what's in the built-in properties, so the only
problem I see is in determining whether a custom
property is text or binary data. Of course you could
base64encode by default, but that won't help much in
the editing department.
On to version control then ; you can always make
setProp handlers for your own custom properties, and
thus write changes to these to a log file.
Unfortunately you can't trap changes in the built-in
properties ; unless of course you use the following
trick : make a library stack to start using or place
in a backScript with the following handler
--
setProp uLOG[pProperty] pNewContent
-- see whose property we're changing
put the long ID of the target into tTarget
-- now update the real property
do merge("set the [[pProperty]] of [[tTarget]] to
[[pNewContent]]"
-- and log the change somewhere
WriteLogEntry tTarget,pProperty,pNewContent
end uLOG
--
Now whenever you want to update a built-in property,
and have the change logged, just use
set the uLOG["rectangle] of field "Foobar" to \
"100,150,300,300"
And whaddayakow, your field gets updated, and you have
a log of the change.
Of course it would be wonderful if the good people
over in Scotland could somehow tie the engine right
into CVS ; but in the meantime we're not without means
ourselves.
Hope my ideas help someone,
Jan Schenkel.
