Inkscape and textext: Deprecation Warning

by Pascal Schulthess

I just came across the following error of textext in Inkscape.

~/.inkscape/extensions/textext.py:55: DeprecationWarning: 
the md5 module is deprecated; use hashlib instead
import os, sys, tempfile, traceback, glob, re, md5, copy

This error arises for textext 0.4.4., Inkscape 0.46 and Python 2.6.2. Fortunately I found a solution at bitbucket. But since I had some problems understanding how to change the python file, I will help you out with a detailed how-to.

Open the textext.py file mentioned in the error message with an editor of your choice. Now change the the lines

55
56

import inkex
import os, sys, tempfile, traceback, glob, re, md5, copy
from lxml import etree

into

import inkex
import os, sys, tempfile, traceback, glob, re, copy
import hashlib
from lxml import etree

Furthermore change

        m = hashlib.md5()
        m.update('%s%s' % (a, kw))
        self.hash = m.hexdigest()[:8]
        return PdfConverterBase.convert(self, *a, **kw)

That’s it. Restart Inkscape and you’re done.
