citeproc-hs is a library for automatically formatting 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: http://xbiblio.sourceforge.net/.

This module documents and exports the library API.

citeproc-hs provides functions for reading bibliographic databases, for reading and parsing CSL files and for generating citations in an internal format, FormattedOutput, that can be easily rendered into different final formats. At the present time only Pandoc and plain text rendering functions are provided by the library.

The library also provides a wrapper around hs-bibutils, the Haskell bindings to Chris Putnam's bibutils, a library that interconverts between various bibliography formats using a common MODS-format XML intermediate.

For more information about hs-bibutils see here: http://code.haskell.org/hs-bibutils/.

citeproc-hs can natively read MODS formatted bibliographic databases.

The following example assumes you have properly installed hs-bibutils. If not you can use bibutils to convert the following bibtex bibliographic database into a MODS collection.

Suppose you have a small bibliographic database, like this one:

 @Book{Rossato2005,
 author="Andrea Rossato",
 title="My First Book",
 year="2005"
 }

 @Book{Rossato2006,
 author="Andrea Rossato",
 title="My Second Book",
 year="2006"
 }

 @Book{Caso2007,
 author="Roberto Caso",
 title="Roberto's Book",
 year="2007"
 }

Save it as mybibdb.bib.

Then you can grab one of the CSL style developed by the Zotero community. Suppose this one:

http://www.zotero.org/styles/apa

saved locally as apa.csl.

This would be a simple program that formats a list of citations according to that style:

 import Text.CSL

 main :: IO ()
 main = do
   m <- readBiblioFile "mybibdb.bib" "bibtex"
   s <- readCSLFile "apa.csl"
   let result = citeproc s m $ [[("Caso2007","p. 10"),("Rossato2005","p. 10"),("Rossato2006","p. 15")]]
   putStrLn . unlines . map (renderPlainStrict) . citations $ result

The result would be:

 (Caso, 2007, p. 10; Rossato, 2005, p. 10, 2006, p. 15)
