Documentation
Regular expression to match calendar user (email) addresses.
The full address should match group 1; "mailto:" will be prepended to
the full address during export, unless it or another URI scheme is
present. If there is a match in group 2, it will be used as the
common name associated with the address (see icalendar-cnparam).
The default value matches names and addresses on lines like:
Ms. Baz <baz@foo.com>
as well as on lines like:
Property: Ms. Baz <baz@foo.com> other data...
Any matching address within a diary entry will be exported as an
iCalendar ATTENDEE property, unless the line on which it appears is also
a match for diary-icalendar-organizer-regexp, in which case it will be
exported as the ORGANIZER property.
This variable was added, or its default value changed, in Emacs 31.1.
