User:Skagedal/Footnote renumbering tool
From Wikipedia, the free encyclopedia
Version 0.1. This script was written for the Schizophrenia article. I actually don't know how generalizable it is.
#!/usr/bin/python
#
# This script will renumber the footnotes on a page, so that the first footnote is number 1,
# the second number 2, etc.
#
# For instance, if you have a page that looks like:
#
# Philip J. Fry{{fn|34}} is a character{{fn|21}} in the Futurama{{fn|25}} series
# ==Notes==
# * {{fnb|21}} Yes, he really is a character
# * {{fnb|25}} By Matt Groening
# * {{fnb|34}} Silly name, huh?
#
# This script will change it to
#
# Philip J. Fry{{fn|1}} is a character{{fn|2}} in the Futurama{{fn|3}} series.
# ==Notes==
# * {{fnb|2}} Yes, he really is a character
# * {{fnb|3}} By Matt Groening
# * {{fnb|1}} Silly name, huh?
#
# As you see, it will not (yet?) reorder your list of footnotes. You'll have to
# do that yourself.
#
# Usage: Give the input on stdin, and you'll get output on stdout.
