Tips For Python Script Extensions
Adding Translation Capability
One can add the ability to have Python text mesages included for translation. To provide an error message, rather than using the Python sys.stderr, use the provided errormsg() function from inkex.py in conjuction with gettext.
You must include the following at the beginning of your Python script:
import inkex import gettext _ = gettext.gettext
Where you wish to have an error message, write the following:
inkex.errormsg(_("This will be written to Python stderr"))
Of course, you may also change "_" to something else if you wish.
Extensions on Mac OSX
On OSX when running extension, it errors out with this error message:
The fantastic lxml wrapper for libxml2 is required by inkex.py ...
to fix that, do the following:
sudo easy_install lxml cd /Applications/Inkscape.app/Contents/Resources/lib mv libxml2.2.dylib libxml2.2.dylib.old ln -s /usr/lib/libxml2.dylib
