The Function: askapache_calendar

Note the screenshot is awesome due to my custom .vimrc. It is missing the randomized color in the code below.

Download OpenBSD Calendars

By default this script will use any calendars in your home directory ~/.calendars. If that directory does not exist when you call this function, it will tell you it is installing the calendars for you. It grabs the list of calendars straight from here. Here is the list:

• calendar.all
• calendar.birthday
• calendar.canada
• calendar.christian
• calendar.computer
• calendar.croatian
• calendar.discord
• calendar.fictional
• calendar.french
• calendar.german
• calendar.history
• calendar.holiday
• calendar.judaic
• calendar.music
• calendar.openbsd
• calendar.pagan
• calendar.russian
• calendar.space
• calendar.ushistory
• calendar.usholiday
• calendar.world
