Should I just look at the output file name? Thanks, William PS, My filter adds some JavaScript to header-includes. I'm doing this as a RawBlock(html) but I think I need to omit it when the HTML will be converted to PDF (wkhtmltopdf complains). -- You received this message because you are subscribed to the Google Groups "pandoc-discuss" group.
