ical2rem
The original iCal to Remind script, first released in 2005.
Reads iCal files and outputs remind-compatible files. Tested ONLY with calendar files created by Mozilla Calendar/Sunbird. Use at your own risk.

In 2005, this was released with the Gnu Public License V2. However, I am changing it to the MIT License, since that provides greater freedom to do with this code what you want.

How I use Remind and Google Calendar together
- My family has a Google Email domain, and our email addresses all end in the same domain. We all use Google Calendars and I want to mail reminders to each of the family members containing both Google Calendar and .reminder information.
- Under my ~/.rem/ directory each family member has a directory. Each directory contains a standard remind file called 'reminders' that at the very least has the line "INCLUDE /home/jalcorn/.rem//ical2rem" and flag files indicating whether they want Daily or Weekly reminders. My reminders files references my standard .reminders file, and I also have a flag so if I run a Test run I'll get it. There's actually a lot more files (I have a big family).

- bin/getgooglecals.sh runs out of crontab and downloads whatever calendars I want. Note that we can also download organization calendars, I've included a public one here (Cleveland Heights Vocal Music Department calendar).
- dailyreminders.sh is linked to weeklyreminders.sh and testreminders.sh so I can run it in different modes. The concatenate the various calendar outputs as a single remind file then send the reminders via email.
Example: .rem/son1/reminders file:
INCLUDE /home/jalcorn/.rem/defs.rem
INCLUDE /home/jalcorn/.rem/float
INCLUDE /home/jalcorn/.rem/son1/ical2rem
fset _weeks() coerce("STRING", (trigdate()-today())/7) + plural((trigdate()-today())/7, " week")
FSET _sfun(x) choose(x, -60, 30, 5, 0)
FSET oldfloat(y,m,d) trigger(MAX(realtoday(), date(y,m,d)))
FSET due(y,m,d) "(" + (date(y,m,d)-trigdate()) + ")"
SET fullmoon moondate(2)
