Package: wikiciteparser
wikiciteparserThis 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).Distributed under the MIT license.Builds on these Python libraries:lupamwparserfromhellmwxmlmwtypesTo installlupafrom pypi.org, you will need libpython and liblua (libpython-devandliblua5.2-devon Debian-base Linux systems).Install this package withpip(eg, in a virtual environment):pip install wikiciteparserExamplesLet's parse the reference section ofthis article:import mwparserfromhell
