About Pandoc citeproc

For Pandoc version before 2.11, a pandoc filter pandoc-citeproc is used. Since Pandoc 2.11, the feature is built-in and activated using --citeproc flag. pandoc_citeproc_arg will return the correct switches depending on the Pandoc version in use.

Details

Non-absolute paths for resources referenced from the in_header, before_body, and after_body parameters are resolved relative to the directory of the input document.
