remmy.pl - A script to convert reminder type files into iCalendar format
remmy.pl < reminderfile > icsfile
This single Perl script convert reminders as used by Dianne Skoll's powerful command line program remind to the iCalendar format (.ics). iCalendar is a widely accepted standard for calendar entries and can be read by popular application like Microsoft's Outlook, Apple's iCal or Google Calendar. remmy.pl parses reminds input file and tries to adopt many of the sophisticated rules for reminders as implemented in remind.
remmy.pl solely relies on Perl, an installation of remind is not necessary.
Note that this script is neither a replacement nor an improvement of remind, in fact, it handles only a very limited subset of remind specification for parsing reminder-type input files.
While remmy is build with reference to RFC2445, full compliance cannot be ensured.
not in use
- Perl UUID::Tiny
- Perl DateTime
COMPATIBILITIES AND LIMITATIONS
The man page of remind lists several examples using the REM command. Currently, remmy supports examples 1 to 18 as given in subsection INTERPRETATION OF DATE SPECIFICATIONS. The output of remmy has been successfully tested with MS Outlook 2003 and Apple iCal 4.0.
remmy supports the local time. It is planned to switch to UTC calendar specification in a future version.
The rule "weekday and day" present is limited in a way that there are no "jumps" to the following month if the next weekday is in the next month. This leads to the functionality that the specified day clusters the rule into the 4 weeks of a month, meaning the rule will always be the 1st, 2nd, 3rd or 4th weekday of every month.
Please report bugs to the author or improve the code by yourself and share the changes. You are encouraged to test remmys output with your preferred calendar application.
