Caption in floatcombination is too low
by Wolfgang Schuster 06 Feb '19

06 Feb '19

Hi Hans, there is a big gap between the content and the caption of each float in a floatcombination environment. %%%% begin example \useMPlibrary[dum] \starttext \startplacefigure[title={First graphic}] \externalfigure[one] \stopplacefigure \startfloatcombination \startplacefigure[title={Second graphic}] \externalfigure[two] \stopplacefigure \stopfloatcombination \stoptext %%%% end example This is probably a result of the following two command from strc-flt.mkvi where you put the caption in a \vbox with a height of 1pt and flush it afterwards in \vtop which shifts the content down to the baseline. As a result of this a empty space was added at the top of the caption. A simple fix for this is to raise the box with the caption when it is added to the combination. %%%% begin strc-flt.mkvi \def\strc_floats_build_box_separate_make {\offinterlineskip \vpack to \onepoint{\box\b_strc_floats_content}\break \vpack to \onepoint{\box\b_strc_floats_caption}} \def\strc_floats_build_box_separate_split#1% {\setbox\scratchbox\vbox{% \setbox\scratchbox\vpack{#1}% \unvbox\scratchbox\relax \setbox\scratchbox\lastbox %\doloop{% \unvbox\scratchbox \setbox\scratchbox\lastbox % \ifdim\ht\scratchbox=2\onepoint \unvbox\scratchbox \setbox\scratchbox\lastbox % \exitloop % \fi}% \splittopskip\zeropoint \global\setbox\b_strc_floats_separate_content\vsplit\scratchbox to \onepoint \global\setbox\b_strc_floats_separate_caption\vsplit\scratchbox to \onepoint \global\setbox\b_strc_floats_separate_content\vpack{\unvbox\b_strc_floats_separate_content\setbox0\lastbox\unvbox0}% \global\setbox\b_strc_floats_separate_caption\tpack{\unvbox\b_strc_floats_separate_caption\setbox0\lastbox\unvbox0}% }} %%%% end strc-flt.mkvi Wolfgang

i-columns.xml small correction
by Taco Hoekwater 06 Feb '19

Hi, In the definition of “setupcolumns”, there are two cd:inherits misrepresented as cd:constants: <cd:parameter name="align"> <cd:constant type="setupalign"/> </cd:parameter> <cd:parameter name="tolerance"> <cd:constant type="setuptolerance"/> </cd:parameter> Best wishes, Taco

math-ini.mkiv: \mathminus
by Wolfgang Schuster 05 Feb '19

05 Feb '19

Hi Hans, the definition for \mathminus uses a en dash for math mode which seems wrong to me. Shouldn’t math use a normal hyphen character? \unexpanded\def\mathminus{\ifmmode –\else\iffontchar\font`−−\else –\fi\fi} Wolfgang

small bug with the 'frac' font feature and linux libertine
by Taco Hoekwater 18 Jan '19

18 Jan '19

Hi, One of Hans van der Meer’s notes has this definition: \definefontfeature[fraction][frac=yes] \definehighlight[textfraction][style={\feature[+][fraction]}] but 'frac' sadly does not quite work correct with Linux Libertine. It looks like somehow the substitution context is off when the command is used immediately after a digit? I am not sure how to debug this properly, nor how to fix it even if I could find root cause of the problem, so I am posting here in the hope someone knows how to fix it. (adding \hskip1sp works as well as a full space, btw) Example attached. Best wishes, Taco

interface file typos and a question
by Taco Hoekwater 17 Dec '18

17 Dec '18

Hi, Whenever I have a few off minutes, I am working on an extension to the wiki. The idea is to have an extra extension tag <syntax>…</syntax> which fetches the html syntax of a ConTeXt command from a wiki database table. More later on that. While working on that though, I found a few small issues with the xml interface files. Here are a few typos (character swaps): <cd:command ategory="fonts" clevel="style" file="font-ini.mkiv" name="switchstyleonly”> <cd:command evel="document" file="buff-ini.mkiv" generated="yes" lcategory="buffer" name="buffer" type="environment" variant="instance”> <cd:command ategory="fonts" clevel="style" file="font-fea.mkvi" name="subtractfeature" variant="direct"> And these two are the only “system conditional”s, which probably means they should just be “system”: <cd:command category="verbatim" file="buff-ver.mkiv" level="system conditional" name="doifelsetypingfile"> <cd:command category="verbatim" file="buff-ver.mkiv" level="system conditional" name="doiftypingfileelse"> A few other commands have no level attribute at all (maybe intentional): <cd:command category="xml" file="strc-tag.mkiv" name="element" type="environment”> <cd:command category="whitespace" file="spac-ver.mkiv" name="unpacked" type="environment”/> <cd:command category="whitespace" file="spac-ver.mkiv" name="locallinecorrection" type="environment”> <cd:command category="columns" file="page-mul.mkiv" name="columnspan" type="environment”> <cd:command category="colors" file="colo-ini.mkiv" name="definepalet"> <cd:command category="colors" file="colo-ini.mkiv" name="transparent" type="environment"> Besides those, I also have an actual question: Is there an intended difference between <cd:sequence> <cd:instance value="framed"/> </cd:sequence> and <cd:sequence> <cd:variable value="highlight"/> </cd:sequence> (cd:instance versus cd:variable)? Best wishes, Taco
