Please review. with old pandoc it fails totally before displaying the version message: pandoc --toc --mathml -s --number-sections -c "http://elyxer.nongnu.org/lyx.css"; -o "ffv1.html" "ffv1.md" pandoc --toc -s --number-sections --latex-engine=xelatex -V geometry:margin=1in -o "ffv1.pdf" "ffv1.md" pandoc: Error producing PDF from TeX source. ! Missing delimiter (. inserted). <to be read again> \let l.432 $context=Q_{0}[l-tl]+\left| make: *** [ffv1.pdf] Error 43 it should probably display something about the version so the user knows where to look for fixing the issue "Order of operation precedence" should mention that this is the "standard C" order so people who know that dont need to read the actual list and memorize it The table in "Border 4.1" is missing a seperator betwen the top slice and the current slice (it does have seperators for the left and right ones The huffman coding mode section is just wrong the examples section is empty and the rest is shuffled around a seemingly random subset of entries in log2_run[] are cyan/green colored The indention depth for ConfigurationRecord( ) is inconsistent and different indention levels are not a multiple of spaces of some constant In 5.3 Slice the "if( i || version > 2 )" has the || interpreted somehow and missing in the pdf output the colorspace_type table is split accross 2 pages in the pdf output, considering its just 4 rows, it would be nice to avoid that split if its possible easily [...] -- Michael GnuPG fingerprint: 9FF2128B147EF6730BADF133611EC787040B0FAB Rewriting code that is poorly written but fully understood is good. Rewriting code that one doesnt understand is a sign that one is less smart then the original author, trying to rewrite it will not make it better.
