pdf bookmarks remarks
by Taco Hoekwater 30 Sep '15

30 Sep '15

Hi, I was writing up my pdf bookmarks article. Two remarks: 1. (for Hans) “With a long heading in a huge font, you might want to add linebreaks by hand. No problem, just use \\. The bookmark code ignores \\, so the bookmark itself won't have a linebreak.” That is not actually true at the moment. Somehow the \\ got converted into a single \, instead of an empty space. Adding \appendtoks \let\\\space \to \simplifiedcommands fixed it, but it would be nice if that was corrected inside ConTeXt… 2. While at it, I also updated the wiki page http://wiki.contextgarden.net/PDF_Bookmarks_and_Headers not much to do, since not much has changed. However, I did add a wiki template for ‘mkii’ (a bit ugly) and split off all mkii remarks into that template. Please have a look. It would be really nice if someone could improve on the template visuals a bit. Best wishes, Taco

Hi Hans, you have to add a parent check to the \placelayeredtext command. \unexpanded\def\placelayeredtext[#1]% {\bgroup \edef\currentlayeredtext{#1}% - \checklayeredtextparent \dodoubleempty\pack_layeredtexts_place} Wolfgang

Hi all, I have re-enabled live.contextgarden.net, with a few changes: * it now always runs mkiv * the actual run happens in a chroot environment, for better security Please try it and see how it works out. (context used is the current from May 2015) Best wishes, Taco

XML Manual
by Wolfgang Schuster 21 Sep '15

21 Sep '15

Hi Hans, a few commands in the XML Manual [1] don’t match with their definitions in lxml-ini.mkiv. The commands - xmlremovedocumentsetup (page 20) - xmlflushdocumentsetups (page 20) take two arguments instead of the document single argument. The command \xmlregistereddocumentsetups (page 16 and 20) takes two arguments as well but the document specifies none. The commands - \xmldoifelseselfempty (page 21) - \xmlremapnamespace (page 21) take only three argument and not four. The commands - \xmlinlineverbatim (page 17) - \xmldisplayverbatim (page 17) - \xmldirectives (page 19) - \xmldirectivesbefore (page 19) - \xmldirectivesafter (page 19) - \xmllast (page 16) take only a single argument and not two. The commands - \xmltags (page 17) - \xmlnofelements (page 17) - \xmlcontextdirective (page 19) don’t exist but are mentioned in the manual. The arguments for the \xmlsetup command on page 19 are shown in the wrong order because it’s \xmlsetup{node}{name}. [1] http://pragma-ade.com/general/manuals/xml-mkiv.pdf Wolfgang

meta-ini.mkiv: \useMPenvironmentbuffer
by Wolfgang Schuster 20 Sep '15

20 Sep '15

Hi Hans, there are two bugs with the \useMPenvironmentbuffer command. 1. The TeX command uses the wrong name to pass the name to Lua: \unexpanded\def\useMPenvironmentbuffer[#1]% - {\clf_mpsetfrombuffer{#1}} + {\clf_mptexsetfrombuffer{#1}} 2. The Lua function in mlib-ctx.lua uses a non existing function to load the buffer content: function mptex.setfrombuffer(name) - environments[#environments+1] = buffers.content(name) + environments[#environments+1] = buffers.getcontent(name) end Wolfgang

math-stc.mkvi: \mathdouble
by Wolfgang Schuster 17 Sep '15

17 Sep '15

Hi Hans, the definition for \mathdouble is wrong (I guess you did this because it’s not really used) because it takes only a code point instead of two (the second always takes the default value 0): \unexpanded\def\mathdouble{\begingroup\dodoubleempty\math_stackers_handle_double} \def\math_stackers_handle_double[#category]% {\math_stackers_direct_double\plusone\plusone {\iffirstargument#category\else\v!bottom\fi}} % will be defined later on \def\math_stackers_direct_double#top#bottom#category#codepoint#text% {\math_stackers_make_double#top#bottom{#category}{#codepoint}{0}{#text}% \endgroup} Wolfgang

math-stc.mkvi: moffset key
by Wolfgang Schuster 16 Sep '15

16 Sep '15

Hi Hans, what is the purpose of the moffset key for \setupmathstackers? There is a definition where you assign a dimension to the key \definemathstackers [\v!wide] [\c!moffset=\thickmuskip,\c!mathclass=\s!rel] but this makes no sense as can be seen in the code below because it isn’t used. \unexpanded\def\math_stackers_unstacked_normal#category#codepoint% {\begingroup \edef\currentmathstackers{#category}% \edef\p_moffset{\mathstackersparameter\c!moffset}% \ifx\p_moffset\empty \else \mskip\scratchmuskip \fi \ifmmode\math_class_by_parameter\mathstackersparameter\else\dontleavehmode\fi {\usemathstackerscolorparameter\c!color \Umathchar\zerocount\defaultmathfamily#codepoint}% \ifx\p_moffset\empty \else \mskip\scratchmuskip \fi \endgroup} Wolfgang
