This Python library wraps Wikipedia's citation processing code (written in Lua) to parse citation templates. For instance, there are many different ways to specify the authors of a citation: this codes maps all of them to the same representation.
This is the underlying code of our "OAbot" (GitHub).

Dependencies: lupa, mwparserfromhell
To install lupa from pypi, you will need libpython and liblua (libpython-dev and liblua5.2-dev on debian-based systems).
Let's parse the reference section of this article:
