MoinMoin: parser/ExcelPastedTable.py

   1 """
   2     MoinMoin wiki - Parser for Excel data copy/pasted into the edit window. 
   3     copied partly from CSV.py
   4 
   5 Installation:
   6 
   7 Copy ExcelPastedTable.py into your data/plugin/parser directory and
   8 restart your MoinMoin. 
   9 
  10 Use:
  11 
  12 put 
  13 
  14 {{{#!ExcelPastedTable
  15 
  16 }}}
  17 
  18 into your editing page
  19 
  20 then copy/paste data from excel in there like this:
  21 
  22 {{{#!ExcelPastedTable
  23 a    b    c
  24 d    e    f
  25 }}}
  26 
  27 
  28 Note:
  29 
  30 This only works if you modify Lib/site-packages/MoinMoin/parser/wiki.py 
  31 
  32 do a search for 'expandtabs' in that file and then replace the line:
  33 
  34         rawtext = self.raw.expandtabs()
  35 
  36 with this line:
  37 
  38         rawtext = self.raw
  39 
  40 I consider this a bug in MoinMoin because whatever is inside {{{#!blah }}} is not supposed
  41 to be touched except by your own parser you write. However wiki.py is getting in there
  42 and expanding the tabs. For excel-pasted data this wont work because it relies on tabs
  43 as separators. 
  44 
  45 Peace Out
