Should I just look at the output file name?As a last resort I set a 'flag' in metadata and inspect that:``````lualocal make_pdflocal Meta = function(meta)-- For use outside this functionmake_pdf = meta['my-filter-pdf']if not (make_pdf) thenlocal includes = meta['header-includes']-- Make sure we have a listif 'List' ~= pandoc.utils.type(includes) thenif nil == includes thenincludes = pandoc.List({ })else-- Assume the current value makes sense as a meta list itemincludes = pandoc.List({ includes })endendincludes:insert(pandoc.RawBlock('html', [=[...]=]))meta['header-includes'] = includesreturn metaendreturn nilendreturn {{ Meta = Meta },main_filter}````````````% pandoc -L my-filter.lua -M my-filter-pdf ...``````At least guaranteed surprise free...--Thanks,WilliamPS, 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).
