How to check if CDF-update is necessary?

skillprogramme

Hi!

I have been using the scripts provided in the solution linked below for updating CDF parameters in cells and libraries with great success. However, I am often interested in checking if a cell does require a CDF update before actually performing the update, since the update requires "append" mode and is rather time consuming (especially when running on a large library). Is there any good way to utilize this script/other functionality to check if an instance in a cell requires a CDF-update without doing the actual update? It can be quite dangerous to run the script on a whole library with edit and not knowing which parameters that changed in the end. 

My hack-around for this has so far been to dump all CDF parameters to a log file, run the script, dump the parameters again and do some parsing and comparison of these logs. I would however prefer something simpler.

Best regards,

Max

    This looks very promising, thanks a lot Andrew!

    I compared the values of the parameters in cdf and effCDF and got many mismatches. I took a look inside CCScreateEffectiveCDFLookalike, and when setting the parameters, I see that they're set to their default value instead of their original value. This is done with:

      ; reset the value to defValue for safety
    (putpropq newParam (getq newParam defValue) value)

    This explains the mismatches I got, since the parameters in cdf and effCDF had different values. As far as I can see, commenting out that line provides the functionality I want. However, why is the parameters set to their default values for safety?
