[Tags: bsd3, library]

citeproc-hs is a Hakell port of Citeproc, a processor for converting citations into a variety of formats using a macro language called Citation Style Language (CSL).

% citeproc-hs - A Haskell Implementation of the Citation Style Language
% Andrea Rossato


[citeproc-hs] is a Haskell implementation of the Citation Style
Language [CSL].

[citeproc-hs] adds to [Pandoc], the famous [Haskell] text processing
tool, a Bibtex like citation and bibliographic formatting and
generation facility.

[CSL] is an XML language for specifying citation and bibliographic
formatting, similar in principle to BibTeX `.bst` files or the binary
style files in commercial products like Endnote or Reference Manager.

[CSL] is used by [Zotero] for bibliographic style formatting, and the
huge number of [CSL] styles developed by the [Zotero] community can
can be downloaded from here:


There are plans to use CSL for adding bibliographic support to future
releases of [OpenOffice](

[citeproc-hs] can process and format citations according to a [CSL]
style, given a [MODS] collection of references.

The Metadata Object Description Schema ([MODS]) is an XML format which
is used by [Bibutils] to interconvert many different bibliographic
database formats, like Bibtex, Endnote, and others.

[Bibutils] can be used to convert Bibtex and other bibliographic
databases to [MODS] collections, which can be thus read by

[Bibutils] also exports a library and a future plan is to use that
library for providing native support for the most widely used
bibliographic databases in [citeproc-hs].

[citeproc-hs] is a library that exports functions to parse [CSL]
styles and [MODS] collections, to process lists of citation groups and
to format the processed output. The output is a Haskell data type that
can be further processed for conversion to any kind of formats (at the
present time plain ASCII and the [Pandoc] native format)

[Pandoc] is a [Haskell] library for converting from one markup format to
another, and a command-line tool that uses this library. It can read
[markdown] and (subsets of) [reStructuredText], [HTML], and [LaTeX]; and
it can write [markdown], [reStructuredText], [HTML], [LaTeX], [ConTeXt],
[RTF], [DocBook XML], [OpenDocument XML], [ODT], [GNU Texinfo],
[MediaWiki markup], [groff man] pages, and [S5] HTML slide shows.


[citeproc-hs] can be downloaded from [Hackage]:


To get the darcs source run:

        darcs get


[citeproc-hs] depends on [hxt], the Haskell XML Tool Box.

In order to install [citeproc-hs] you need to install [hxt] and its
dependencies. You can download everything from [Hackage]:


Every package downloaded form [Hackage] can be installed with those
simple commands:

        runhaskell Setup.lhs configure
        runhaskell Setup.lhs build
        runhaskell Setup.lhs install

This last step requires `root` privileges.

If you don't have `root` privileges you can install citeproc-hs and
*all* its dependencies locally with these commands:

        runhaskell Setup.lhs configure --user --prefix=$HOME
        runhaskell Setup.lhs build
        runhaskell Setup.lhs install --user

Using citeproc-hs with Pandoc

If you want to use [citeproc-hs] with [Pandoc] you need to install
[citeproc-hs] first, get the [Pandoc] source code and compile it with
the `-f citeproc` flag:

        runhaskell Setup.lhs configure -f citeproc
        runhaskell Setup.lhs build
        runhaskell Setup.lhs install

Citations are inserted like simple reference links:


where `Rossato2006` is the reference id (or citation key) used in the
bibliographic database.

Citation groups are also possible. Each citation is separated by a

    [Rossato2006; Pascuzzi2002]

The use of locators is also possible:

    [Rossato2006@ p. 10; Pascuzzi2002@ cap. 12]

To automatically format citations and generate the bibliography, run
[Pandoc] with the `--csl` and `--mods` flags:

    pandoc --csl cslStyle.csl --mods modsCollection.xml text.markdown > text.html

Obviously you can export the text into any of the formats supported by

Some examples can be found in the `test` directory of the source tree.

You can try them with:

    pandoc --csl apa.csl --mods modsCollection.xml test.markdown
    pandoc --csl apa.csl --mods modsCollection.xml test_note.markdown


No further documentation is so far available and even haddock
generated documentation is at a very early stage.

Some usage examples can be found in the `test` directory of the
source tree.

Known Issues

[citeproc-hs] is in an early stage of development and the [CSL]
implementation is not complete yet.

Specifically the following options are not implemented:

 - "collapse" (citation collapsing)
 - "hanging-indent"
 - "second-field-align"
 - "line-spacing"
 - "entry-spacing"

The [MODS] parser needs some refinement too.

[Bruce D'Arcus], the author of [CSL], has been very kind and patient
with me when I was trying to understand the [CSL] schema, and provided
me with ideas, comments and suggestions that made it possible to come
to something usable.

[John MacFarlane], the author of [Pandoc], has been very supportive of
the project and provided a lot of useful feed back, comments and
