Current issues

Excerpt from an email I sent to the inkscape-devel list:

Hello,

I hope this list is the correct one for this kind of question: Has anyone managed to get http://wiki.inkscape.org/wiki/index.php/PythonEffectTutorial to work without major changes? It failed for me both on a gentoo system and on a pretty vanilla Ubuntu 8.04 box. I don't know if I will find the time to edit the wiki page according to the current lxml behaviour, but I might give it a try. Additionally Ishmal(I think) said on irc/jabber that lxml might not be used in the future anymore anyway.

Now for the list of problems I encountered:

  • Simply making the file executable and putting it into ~/.inkscape/extensions/ is not sufficient, it won't find inkex there, but no problem, simply add

import sys sys.path.append('/usr/share/inkscape/extensions') # or another path, as appropriate for your installation to the top of it. A minor problem.

  • All the getElementsByTagName, getAttribute, createElement,... methods are unknown to lxml, at least in the versions here (1.3.6). Inkscape returns the python error message ending with:

File "/home/dhornun/.inkscape/extensions/helloworld.py", line 32, in effect svg = self.document.getElementsByTagName('svg')[0] AttributeError: 'etree._ElementTree' object has no attribute 'getElementsByTagName' If this is not a problem on the distributions' side, those can probably be fixed by adapting the code to reflect lxml's current API.

Hopefully I'll find the time to fix this either on my machine or here in the wiki. The first point was fixed already. --Rubikcube 07:32, 30 July 2008 (UTC)
