Python bindings have been recently added to gnucash. There is still very little documentation and probably few people would know how to use it. While not a manual, this page was created in the hope to provide information for those interested in gnucash and python.

• http://article.gmane.org/gmane.comp.gnome.apps.gnucash.devel/23613 "Re: documentation for python bindings" with some pointers on how to look up the existing documentation

Setting things up

I use ipython for an interactive shell. If you prefer something else, let us know if there is any difference.

export PYTHONPATH=$PYTHONPATH:/export/gnucash/lib/python2.7/site-packages

This adds the gnucash python bindings to your PYTHONPATH assuming that your gnucash resides in /export/gnucash. You can then either start up an interactive python session with ipython or call your script to be executed.

gnucash-env ipython
gnucash-env python $scriptyouwanttorun

Note: to install ipython run

 sudo easy_install ipython

Documentation

As pointed out in the introductory paragraph, the documentation is rather slim at this point in time. Here are some sources where you might be able to find what you are looking for. Generally speaking, this is not yet end-user friendly stuff.

• Have a look at the page python-bindings in doxygen source-documentation
• example scripts from the source code and in doxygen
• business functions documentation
• inside ipython
  • big long list of stuff
    • import gnucash.gnucash_core_c
    • help(gnucash_core_c)
    • dir(gnucash_core_c)
  • higher abstraction level help
    • import gnucash.gnucash_core
    • import gnucash.gnucash_business
    • help(gnucash.gnucash_core)
    • help(gnucash.gnucash_business)

Again, http://article.gmane.org/gmane.comp.gnome.apps.gnucash.devel/23613 contains some more hopefully useful pointers.
