qcal is a quick calendar application for CalDAV servers written in Go. In contrast to other tools it does not cache anything. It can fetch multiple servers / calendars in parallel which makes it quite fast.
Its main purpose is displaying calendar data. Nevertheless it supports basic creation and editing of entries.
This simply displays all appointments for the next x days (configured in config.json):
This shows all appointments for today:
This only shows appointments from calendar 0 for the next seven days:
qcal -c 0 -7
This shows all appointments from 01.10.2021, 00:00h to 31.10.2021, 23:59:59 (Note: This is in UTC!):
qcal -s 20211001T000000 -e 20211031T235959
This displays all avaliable calendars with their numbers and colors:
Even though the abillity to create new appointments is limited, it is easy to create simple appointment types.
This creates an appointment on 01.12.2021 from 15:00h to 17:00h with the summary of "Tea Time":
qcal -n "20211201 1500 1700 Tea Time"
This creates a whole day appointment with a yearly recurrence in your second calendar (first is 0):
qcal -c 1 -n "20211114 Anne's Birthday" -r y
This creates a multiple day appointment:
qcal -n "20210801 20210810 Holiday in Thailand"
This shows the next 7 days of appointments from calendar 3 with filenames ("foobarxyz.ics"):
qcal -c 2 -7 -f
This edits the selected iCAL object in your $EDITOR (i.e. vim). When you save-quit the modified object is automatically uploaded:
qcal -c 2 -edit foobarxyz.ics
You can view received appointments in neomutt with qcal! Put this in your mailcap (usually in .config/neomutt):
text/calendar; qcal -p; copiousoutput
You can get reminders of your appointments 15 mins in advance with this one liner:
EVENT=$(qcal -cron 15); [[ $EVENT ]] && notify-send "Next Appointment:" "\n$EVENT"
