# This script is a wrapper around pandoc that uses pandoc's | |
# builtin citeproc support to generate a markdown bibliography | |
# from bibtex. | |
# | |
# Inspired by Jacob Barney's [bib2mkd][] script. | |
# | |
# [bib2mkd]: http://jmbarney.dyndns.org/?/linux/bib2mkd/ | |
# | |
# Simplest usage: | |
# | |
# cat file.bib | bibtex2markdown | |
# | |
# will send to STDOUT a markdown bibliography containing all the | |
# publications from file.bib on STDOUT. | |
# | |
# Filtering: | |
# | |
# cat file.bib | bibtex2markdown smith jones | |
# | |
# will send to STDOUT a markdown bibliography containing all the | |
# publications from file.bib whose citekeys begin with | |
# 'smith' or 'jones'. | |
# | |
# Filtering with Regexs: | |
# | |
# cat file.bib | bibtex2markdown ".*nes" | |
# | |
# will send to STDOUT a markdown bibliography containing all the | |
# publications from file.bib whose citekeys begin with something | |
# that matches the regex ".*nes", e.g., 'jones1992' and | |
# 'ernest1878'. | |
# | |
# Using a default bibtex file: | |
# | |
# bibtex2markdown -d | |
# | |
# If the first argument is '-d', then will use the file given by | |
# the variable defaultbib, defined below, rather than reading | |
# STDIN. | |
defaultbib="/Users/david/.pandoc/default.bib" | |
