Hi John,
That sounds great. I just now set up the code on
GitHub<https://github.com/cwalston/spotlight.factor>,
and added the factorcode BSD license line.
First time for me; hope I got the hairy thing right. Being brand new to
collaborative coding, I don't know
the etiquette on adding contributors names. I got so much help, I reckon
other names should be added.
Let me know what to do about that.
The solution to the problem of gathering all kMDItem atributes was staring
me in the face, but I didn't
see it until this evening. It's added in the GiHub code.
I hope folks can put spotlight.factor through its paces, & suggest
improvements.
Thanks to all for the patient help.
Cheers!
