Text.CSL

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://citationstyles.org/.

This module documents and exports the library API.

Introduction

citeproc-hs provides functions for reading bibliographic databases, for reading and parsing CSL files and for generating citations in an internal format, Formatted, 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://hackage.haskell.org/package/hs-bibutils.

citeproc-hs can natively read MODS and JSON formatted bibliographic databases. The JSON format is only partially documented. It is used by citeproc-js, by the CSL processor test-suite and is derived by the CSL scheme. More information can be read here: http://citationstyles.org/.

A (git) repository of styles can be found here: https://github.com/citation-style-language/styles.

Overview: A Simple Example

The following example assumes you have installed citeproc-hs with hs-bibutils support (which is the default).

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

 @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 styles that come with the test-suite for CSL processors. Suppose this one:

https://bitbucket.org/bdarcus/citeproc-test/raw/18141149d1d3/styles/apa-x.csl

saved locally as apa-x.csl.

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

 import Text.CSL

 cites :: [Cite]
 cites = [emptyCite { citeId = "Caso2007"
                    , citeLabel = "page"
                    , citeLocator = "15"}
         ,emptyCite { citeId = "Rossato2006"
                    , citeLabel = "page"
                    , citeLocator = "10"}
         ]

 main :: IO ()
 main = do
   m <- readBiblioFile "mybibdb.bib"
   s <- readCSLFile "apa-x.csl"
   let result = citeproc procOpts s m $ [cites]
   putStrLn . unlines . map renderPlain . citations $ result

The result would be:

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

Reading Bibliographic Databases

readBiblioFile :: FilePath -> IO [Reference]
