MoinMoin: attachment:PageCompare.py of GermanTranslation

   1 """
   2     MoinMoin - Macro to compare pages, e.g. to find out, if a page with a
   3     german translation is still "in sync" with the english original page.
   4 
   5     If you generate some sort of "derived work" of a page, go to page info
   6     of the original page and copy & paste the PageCompare macro shown there
   7     to your derived page.
   8     
   9     Usage:
  10         [[PageCompare(masterpagename,masterdate,mastersha)]]
  11 
  12         masterpagename	name of the master (original) page
  13 	masterdate	original date of master page (only for information)
  14 	mastersha	original SHA digest of master page
  15 
  16     Examples:
  17 	[[PageCompare(HelpIndex,2002-02-02 13:45:00,5AE4EF821719D7AD65E3D258178E851CA9B39320)]]
  18         This will compare the given mastersha with the current sha of the
  19 	masterpage. If they are the same, everything is still in sync and you
  20 	get an appropriate message. If not, you will be informed, that the
  21 	masterpage has changed and therefore the current page is not in sync any
  22 	more (e.g. because it was a translation of the older masterpage).
