Variable: diary-icalendar-summary-regexp
diary-icalendar-summary-regexp is a customizable variable defined in
diary-icalendar.el.gz.
Value
nil
Documentation
Regular expression to match summary in an entry.
If this is nil, the first line of the entry (after the date and time specification) is used as the summary. Thus, it is only necessary to set this variable if you want to export diary entries where the text to be used as the summary does not appear on the first line of the entry. In that case, the summary should match group 1 of this regexp.
This variable was added, or its default value changed, in Emacs 31.1.
