pandoc-citeproc: Supports using pandoc with citeproc

[ bsd3, library, program, text ] [ Propose Tags ]

The pandoc-citeproc library exports functions for using the citeproc system with pandoc. It relies on citeproc-hs, a library for rendering bibliographic reference citations into a variety of styles using a macro language called Citation Style Language (CSL). More details on CSL can be found here:

Currently this package includes a copy of the citeproc-hs code. When citeproc-hs is updated to be compatible, this package will simply depend on citeproc-hs.

This package also contains two executables: pandoc-citeproc, which works as a pandoc filter (pandoc >= 1.12), and biblio2yaml, which converts bibliographic databases to a yaml format suitable for inclusion in pandoc YAML metadata.

Readme for pandoc-citeproc-

[back to package description]


This package provides a library and executable to facilitate the use of citeproc with pandoc 1.12 and greater. (Earlier versions of pandoc have integrated citeproc support.)

The current version of the package includes code from citeproc-hs, which has not been updated for some time. When citeproc-hs is brought up to date, this code can be removed and this package will depend on citeproc-hs.


The pandoc-citeproc executable is a filter that takes a JSON-encoded Pandoc document, formats citations and adds a bibliography, and returns a JSON-encoded pandoc document.

To process citations with pandoc, call pandoc-citeproc as a filter:

pandoc --filter pandoc-citeproc -s -o output.html

The bibliography will be put into a pandoc Div container with class references.

pandoc-citeproc will look for the following metadata fields in the input:

bibliography: A path, or YAML list of paths, of bibliography files to use. These may be in any of the formats supported by bibutils.

Format            File extension
------------      --------------
MODS              .mods
BibLaTeX          .bib
BibTeX            .bibtex
RIS               .ris
EndNote           .enl
EndNote XML       .xml
ISI               .wos
MEDLINE           .medline
Copac             .copac
JSON citeproc     .json

references: A YAML list of references. Each reference is a YAML object. The format is essentially CSL JSON format. Here is an example:

- id: doe2006
    family: Doe
    given: [John, F.]
  title: Article
  page: 33-34
    year: 2006
  type: article-journal
  volume: 6
  container-title: Journal of Generic Studies

The contents of fields will be interpreted as markdown when appropriate: so, for example, emphasis and strong emphasis can be used in title fileds. Simple tex math will also be parsed and rendered appropriately.

csl or citation-style: Path to a CSL style file. If the file is not found relative to the working directory, pandoc-citeproc will look in the $HOME/.csl directory (or C:\Users\USERNAME\AppData\Roaming\csl in Windows 7).

citation-abbreviations: Path to a CSL abbreviations JSON file. The format is described here. Here is a short example:

{ "default": {
    "container-title": {
            "Lloyd's Law Reports": "Lloyd's Rep",
            "Estates Gazette": "EG",
            "Scots Law Times": "SLT"

The metadata must contain either references or bibliography or both as a source of references. csl and citation-abbreviations are optional. If csl is not provided, chicago-author-date.csl will be used by default.


biblio2yaml will convert an existing bibliography (in any of the formats listed above) into a YAML bibliography of the sort that can be included in the references field of pandoc's metadata.

Simplest usage is

biblio2yaml BIBFILE

which will convert BIBFILE and print the result to stdout. The format will be derived from BIBFILE's extension, according to the table above.

biblio2yaml can also be used as a pipe, taking inptu from stdin, in which case the format must be specified explicitly using the -f/--format flag.


Those who use pandoc as a library (e.g. in a web application) will need to use this module to process citations.

The module exports two functions, processCites, which is pure and accepts a style and a list of references as arguments, and processCites', which lives in the IO monad and derives the style and references from the document's metadata.
