I discovered and had a look at sphinxcontrib-newsfeed, a well made Sphinx extension to generate an rss feed from my blog entries.

What I’m missing is an auto-discovery function. It would be enough to add a :glob: option as for .. toctree::. I have to add myself every blog entry also to the .. feed:: directive. For example in my index.rst I have:

.. feed::
   :rss: index.rss
   :title: Luc's blog


Code changes

  • Removed some internal dependencies from djangosite to north.
  • Added German translations for the new things in welfare.jobs.Candidature.
  • There were still some print_ function calls instead of print statements hanging around. E.g. in lino.tutorial.auto_create and lino.tutorial.human.
  • Added “Den” as name prefix in lino.modlib.contacts.utils.
  • html2odf failed when it was called with a plain string. Added this edge case to the tested docstring.


  • Tried to understand how to make it configurable per table whether rows should have fixed height or not.
  • There is a language switching problem in http://belref.lino-framework.org, maybe caused by the upgrade to Django 1.5. This is probably because lino.utils.auth does not collaborate well with Django’s LocaleMiddleware. Needs more thinking. Not urgent.

Fiddling with the Python-UNO bridge

Trying to print in one of the online demos still fails with a message

Action “sales.InvoicesByJournal.do_print” failed for Rechnung “#5 (Verkaufsrechnungen 2013)”: Extension of result file is “pdf”. In order to perform conversion from ODT to this format we need to call LibreOffice. But the Python interpreter which runs the current script does not know UNO, the library that allows to connect to LibreOffice in server mode. If you can’t install UNO in this Python interpreter, you can specify, in parameter “pythonWithUnoPath”, the path to a UNO-enabled Python interpreter. One such interpreter may be found in /program.. Ein Fehlerbericht wurde an den Systemverwalter geschickt.

Until recently it worked. I guess that this is due to my switch to virtualenv, because python /usr/share/doc/python-openoffice/examples/check-installation reports:

Can't import the uno-bridge module 'uno'.
Make sure the package 'openoffice.org-pyuno' is installed,
is matching your Python version 2.6 and the file uno.py is on
For Debian, Ubuntu and related distributions, the package
is called, eg. 'python-uno'.

These instructions seem very clear, but unfortunately I could not find out which package they mean.

Description: Python-UNO bridge
 The Python-UNO bridge allows use of the standard OpenOffice.org API with the Python scripting language. It additionally allows others to
 develop UNO components in Python, thus Python UNO components may be run within the OpenOffice.org process and can be called from C++ or the

 built in StarBasic scripting language.

Tried also (once again) to understandwhat OOo itself writes about this mysterious Python-UNO bridge… but sorry, but I still don’t understand most of this.

Appy pythonWithUnoPath`parameter is `’/etc/openoffice.org3/program/python’. Indeed there is no such file on the system. But that doesn’t mean so much Appy maybe never used this parameter, it uses it only when python-uno cannot be imported.
