  24       <div class="date"> 4th January 2017</div>
  25       <div class="body"><p>Do you have a large <a href="https://icalendar.org/">iCalendar</a>
  26 file with lots of old entries, and would like to archive them to save
  27 space and resources?  At least those of us using KOrganizer know that
  28 turning on and off an event set become slower and slower the more
  29 entries are in the set.  While working on migrating our calendars to a
  30 <a href="http://radicale.org/">Radicale CalDAV server</a> on our
  31 <a href="https://freedomboxfoundation.org/">Freedombox server</a/>, my
  32 loved one wondered if I could find a way to split up the calendar file
  33 she had in KOrganizer, and I set out to write a tool.  I spent a few
  34 days writing and polishing the system, and it is now ready for general
  35 consumption.  The
  36 <a href="https://github.com/petterreinholdtsen/ical-archiver">code for
  37 ical-archiver</a> is publicly available from a git repository on
  38 github.  The system is written in Python and depend on
  39 <a href="http://eventable.github.io/vobject/">the vobject Python
  40 module</a>.</p>
  41
  42 <p>To use it, locate the iCalendar file you want to operate on and
  43 give it as an argument to the ical-archiver script.  This will
  44 generate a set of new files, one file per component type per year for
  45 all components expiring more than two years in the past.  The vevent,
  46 vtodo and vjournal entries are handled by the script.  The remaining
  47 entries are stored in a 'remaining' file.</p>
  48
  49 <p>This is what a test run can look like:
  50
  51 <p><pre>
  52 % ical-archiver t/2004-2016.ics

  74 <p>As you can see, the original file is untouched and new files are
  75 written with names derived from the original file.  If you are happy
  76 with their content, the *-remaining.ics file can replace the original
  77 the the others can be archived or imported as historical calendar
  78 collections.</p>
  79
  80 <p>The script should probably be improved a bit.  The error handling
  81 when discovering broken entries is not good, and I am not sure yet if
  82 it make sense to split different entry types into separate files or
  83 not.  The program is thus likely to change.  If you find it
  84 interesting, please get in touch. :)</p>
