calfilter

DESCRIPTION:

calfilter is a small library to assist in writing filtering programs for icalendar files or streams. It can be used for various purposes, including:

  • removing items from icalendar feeds that are not interesting to you

  • removing private information from your own calendar before publishing it to others

  • reformatting a provided calendar to highlight particular information

A calfilter script does most of its work using the filter_calendars method.

FEATURES:

  • require 'calfilter/tripit' to add some methods specific to tripit.com calendar feeds.

  • require 'calfilter/cgi' to automatically turn your filter into a CGI script. The CGI object is available as CalFilter::CGI.

SYNOPSIS:

require 'calfilter'

cals = filter_calendars('some_url') do |cal|
    cal.keep(:events)  # not journals, todos, or freebusys

    cal.filter_events do |evt|
        # Remove events I've marked private
        evt.remove if evt.description =~ /PRIVATE/
        # Don't reveal phone numbers of my contacts
        evt.description.sub! /\d{3}-\d{4}/, '###-####'
    end
end

REQUIREMENTS:

calfilter depends on the icalendar gem.

INSTALL:

sudo gem install calfilter
