Side figure bug in mkiv?
by Duncan Hothersall 19 Jul '19

19 Jul '19

I think I have identified a bug in the side figure mechanism which is demonstrated by the minimal example below. The {\bf …} construct causes the para in which it appears to stop behaving properly with the side figure, and the text overflows. The preceding and following paras which don't have {\bf …} do behave properly. I wondered if emphasis like \bf should be done differently (with a start/stop mechanism?) in mkiv, but I found nothing to suggest it. \starttext Blah blah. \placefigure[right,none]{}{\externalfigure[cow][width=0.30\makeupwidth]} Blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah. Blah blah blah blah blah blah blah blah. {\bf Blah blah} blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah. Blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah. \stoptext Thanks for any help. Duncan

Using \currentreferencenumber triggers “has a hidden number” in log file
by Marco Patzer 18 Jul '19

18 Jul '19

Hi, I use \enabletrackers [structures.referencing.empty] to catch references by number to sections without a number. The log file contains “has a hidden number…” in that case. I have a command that uses \currentreferencenumber which triggers the “has a hidden number…” warning in the log file. But that command takes care not to output the contents of that variable. But merely using it in an \doif\currentreferencenumber is sufficient to trigger the log message. Example: \enabletrackers [structures.referencing.empty] \def\foo[#1]{%% \doifreferencefoundelse{#1}{%% \doifelse\currentreferencenumber\emptyreference {Foo}{Bar}}%% } \setuphead [section] [number=no] \starttext \startsection [title=Foo, reference=sec:foo] \samplefile{knuth} \stopsection \foo[sec:foo] \stoptext Then check the log file for “has a hidden number”. 1) How to not trigger the log message when checking \currentreferencenumber? Or alternatively 2) Is there a better way to find invisible references? Marco

Column spacing in MathML in mkiv
by Duncan Hothersall 18 Jul '19

18 Jul '19

Hi all. If I want to set the space between columns in a MathML <mtable>, how do I do it? Minimal non-working example below (set the attribute columnspacing to anything you like and it seems to be ignored). Is this a bug or is there a feature I've missed? \usemodule[mathml] \starttext \xmlprocessdata{}{<formula> <math xmlns='http://www.w3.org/1998/Math/MathML'> <mtable columnalign="right center left" columnspacing="1em"> <mtr> <mtd><mi>a</mi><mi>b</mi></mtd> <mtd><mo>=</mo></mtd> <mtd><mi>c</mi><mi>d</mi></mtd> </mtr> <mtr> <mtd><mi>e</mi><mi>f</mi></mtd> <mtd><mo>=</mo></mtd> <mtd><mi>g</mi><mi>h</mi></mtd> </mtr> </mtable> </math></formula>}{} \stoptext Many thanks. Duncan

bug with fonts in LMTX (Win7)?
by Pablo Rodriguez 18 Jul '19

18 Jul '19

Hi Wolfgang, I’m afraid LMTX cannot use \ss and \cg fonts in this sample (on Win7): \definefontfamily[mainface][rm][TeX Gyre Heros] \definefontfamily[mainface][mm][TeX Gyre Termes Math] \definefontfamily[mainface][ss][Gill Sans MT][tf=file:GIL_____.TTF] \definefontfamily[mainface][tt][Cousine] \definefontfamily[mainface][cg][Arial Narrow][tf=file:ARIALN.TTF] \setupbodyfont[mainface] \startbuffer \ConTeXt\ is awesome!\par \stopbuffer \starttext \startTEXpage[offset=1em] \getbuffer \ss\getbuffer \tt\getbuffer \cg\getbuffer \stopTEXpage \stoptext The fonts are there (as reported in https://mailman.ntg.nl/pipermail/ntg-context/2019/094955.html) I don’t know whether this issue could be fixed. Many thanks for your help, Pablo -- http://www.ousia.tk

Spacing after combination
by Marco Patzer 16 Jul '19

16 Jul '19

Hi! Is there a way to influence the spacing after a combination is placed? \useMPlibrary [dum] \starttext \startcombination [2*2] \startcontent \externalfigure \stopcontent \startcaption Foo \stopcaption \startcontent \externalfigure \stopcontent \startcaption Bar \stopcaption \startcontent \externalfigure \stopcontent \startcaption Lorem \stopcaption \startcontent \externalfigure \stopcontent \startcaption Ipsum \stopcaption \stopcombination \samplefile{knuth} \stoptext I know I could wrap it in a float and use the float to control the spacing, but it would be great if I could do without that float.

Columnsets not balanced
by Sytse Knypstra＠home.nl 15 Jul '19

15 Jul '19

Dear list, In the following example I would like to have the two columns balanced, i.e. with equal number of lines in both columns. But contrary to the option in the definition, all text is put in the leftmost column and the right-hand column remains empty. \definecolumnset[Two][balance=yes] \starttext \startcolumnset[Two] \input knuth \stopcolumnset \stoptext How can I automatically obtain balanced columns?
