pandoc-citeproc-preamble is a JSON filter for Pandoc which inserts a preamble before the output that Pandoc's citeproc filter appends to the document. This preamble might include a heading (e.g. "Bibliography") and raw markup to format the bibliography for the output format.
Users of Debian 10 or later or Ubuntu 17.04 or later: apt-get install pandoc-citeproc-preamble. Users of Debian 9: enable
backports, and then apt-get install -t stretch-backports pandoc-citeproc-preamble.
Otherwise, pandoc-citeproc-preamble uses the standard Haskell
toolchain and is available from Hackage, so you should just be able to
cabal install pandoc-citeproc-preamble.
If you are not a Haskell programmer, you might find it easier to
- install Stack;
- ensure that
~/.local/binis in your shell's PATH - run
stack install pandoc-citeproc-preamble.
Add --filter pandoc-citeproc-preamble somewhere after --citeproc, e.g.
$ pandoc -s --citeproc --bibliography=~/doc/mine.bib --filter pandoc-citeproc-preamble ~/doc/my_essay.mdwn -o ~/my_essay.pdf
In this case, since the output format is LaTeX,
pandoc-citeproc-preamble will look for the preamble in the file
data_dir/citeproc-preamble/default.latex where data_dir is your
Pandoc user data directory, as reported by pandoc --version. You
may specify a different preamble by setting document metadata like this:
$ pandoc ... --filter pandoc-citeproc-preamble -M citeproc-preamble=~/my_preamble.tex ...
Please see "Rationale", below, for why it would defeat the purpose of
this script to include a value for citeproc-preamble in your input
file's YAML metadata block.
Please see my ~/.pandoc/citeproc-preamble/default.latex, which was inspired by this guide.
One motivation for authoring with Pandoc is that one's input files are agnostic with regard to the output format they will eventually be compiled to: it should not be necessary to include in one's input file, for example, LaTeX code to format the bibliography.
When compiling to PDF (which is probably the most common case for users of Pandoc's citeproc filter), formatting code is usually required to have the entries of Pandoc's bibliography line up with each other; by default, all entries except the first will be indented. Another common customisation is to set up a hanging indent for bibliography entries.
Since Pandoc's citeproc filter doesn't provide any facility to add formatting control code to its output, pandoc-citeproc-preamble is necessary to avoid the user being forced to add their control code to the end of their input files, thereby losing the input file's agnosticity with regard to output format.
