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 . Currently this package includes a heavily revised 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 an executable: pandoc-citeproc, which works as a pandoc filter, and also has a mode for converting bibliographic databases a YAML format suitable for inclusion in pandoc YAML metadata.
