Description

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, `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://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 (renderPlainStrict) . citations $ result

The result would be:

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

# Reading Bibliographic Databases

readBiblioFile :: FilePath -> IO [Reference]Source

Read a file with a bibliographic database. The database format is recognized by the file extension.
