This has been reported to the iCal::Parser author. # version 0.5.1 2007-03-21 # - BUG: Handle multiple calendars on STDIN # - add --heading option for priority on section headers # version 0.5 2007-03-21 # - Add more help options # - --project-lead-time option # - Supress printing of heading if there are no todos to print # version 0.4 # - Version 0.4 changes all written or inspired by, and thanks to Mark Stosberg # - Change to GetOptions # - Change to pipe # - Add --label, --help options # - Add Help Text # - Change to subroutines # - Efficiency and Cleanup # version 0.3 # - Convert to GPL (Thanks to Mark Stosberg) # - Add usage # version 0.2 # - add command line switches # - add debug code # - add SCHED _sfun keyword # - fix typos # version 0.1 - ALPHA CODE. =head1 SYNOPSIS cat /path/to/file*.ics | ical2rem.pl > ~/.ical2rem All options have reasonable defaults: --label Calendar name (Default: Calendar) --lead-time Advance days to start reminders (Default: 3) --todos, --no-todos Process Todos? (Default: Yes) --heading Define a priority for static entries --help Usage --man Complete man page Expects an ICAL stream on STDIN. Converts it to the format used by the C<remind> script and prints it to STDOUT. =head2 --label ical2rem.pl --label "Bob's Calendar" The syntax generated includes a label for the calendar parsed. By default this is "Calendar". You can customize this with the "--label" option. =head2 --lead-time ical2rem.pl --lead-time 3 How may days in advance to start getting reminders about the events. Defaults to 3. =head2 --no-todos ical2rem.pl --no-todos If you don't care about the ToDos the calendar, this will surpress printing of the ToDo heading, as well as skipping ToDo processing. =head2 --heading ical2rem.pl --heading "PRIORITY 9999" Set an option on static messages output. Using priorities can made the static messages look different from the calendar entries.
