I added a system command to Templater. The command looks like the following:
/usr/local/bin/icalBuddy -npc -iep "title,datetime,attendees" -b -\ -po "datetime,title" -ps "|: |\\n |" eventsToday
This gets me the agenda for the day:
and for my weekly overview I use this command:
/usr/local/bin/icalBuddy -npc -nrd -iep "title,datetime" -b -\ -po "datetime,title" -ps "|: |\\n |" eventsFrom:"date -v+monday '+%F 00:00:00 %z’" to:"date -v+1w ‘+%F 00:00:00 %z’"
