Hi, Bo.  There should be a file called DETAILS (in doc/DETAILS in the
gnupg source, or maybe included with your local installation) that
describes in detail the meaning of the --with-colons output.  It's
exactly the reference you're looking for when writing a program to parse
the --with-colons output.

Good luck!


$ head gnupg2-2.0.14/doc/DETAILS
                                                              -*- text -*-
Format of colon listings
First an example:

$ gpg --fixed-list-mode --with-colons --list-keys \
   --with-fingerprint --with-fingerprint wk at gnupg.org
