Wrong section space after placefigure with newcolumnsets
by Charles Vejnar 05 Apr '18

05 Apr '18

Hi, I am placing figures in a columnset. The next header (section, subsection...) following the figure has always missing vertical space. See the normal space after "One subsection" and "Four subsection" but reduced space after "Two subsection" and "Three subsection" in the example below. Tested with ConTeXt ver: 2018.04.04 and LuaTeX, Version 1.07.0. This seems to be the opposite problem as the one described recently in the thread "Bug in wrapped placefigure". Any solution or fix? Thank you very much for your help.

MetaFun: Rotate picture without rotating labels
by Henri Menke 05 Apr '18

05 Apr '18

Dear list, In the MWE below I would like py to be px rotated by 90 degrees but the labels should not be rotated. Is it possible? Cheers, Henri --- \startMPpage path p ; p := origin .. (2,1) .. (3,0) .. (2,-1) .. (-2,1) .. (-3,0) .. (-2,-1) .. cycle ; picture px, py ; px := image ( draw p scaled 6 ; label("$+$",(+10,0)); label("$-$",(-10,0)); ) ; py := px rotated 90 ; draw px ; draw py ; % meh :/ \stopMPpage

Saving Metafun Graphic for use outside ConTeXt
by Keith McKay 05 Apr '18

05 Apr '18

Dear Readers, I have been playing about with METAFUN over the last few days trying to get a feel for it. I was wondering if it is possible to save the graphics produced in a context document for use outside. On looking at the Metapost manual I see you can using the following commands save a graphic as an svg file. /outputformat := "svg"; / /outputtemplate := "test.svg";/ // I have tried adding this to some MPcode in a ConteXt document but these lines seem to be ignored since no svg file is produced apart from the usual ConTeXt files. Is this expected behaviour? I have been able to get svg files using mpost on the command line. Here is a minimum working example (which I'm sure could be coded more elegantly): /\starttext/ // /\startMPcode/ // /outputformat := "svg";/ // /outputtemplate := "test.svg";/ // /beginfig(1)/ // /randomseed:= uniformdeviate infinity;/ // /path pat;/ // /x:=uniformdeviate(5);/ // /y:=uniformdeviate(5);/ // /pat:=(x,y);/ // /for i = 1 upto 5:/ // /a:=uniformdeviate(5);/ // /b:=uniformdeviate(5);/ // /pat := pat...(a,b);/ // /endfor;/ // /pat:=pat..(0,5);/ // /draw pat scaled 10pt;/ // /picture pic;/ // /pic:=currentpicture;/ // /endfig;/ // /\stopMPcode/ // /\stoptext/ Best Wishes Keith //

Circled text in metapost
by Gerhard Kugler 04 Apr '18

04 Apr '18

Hi, in documentations I can find various examples of circled text. But copying them I had no success till now. I want to place text in half circles of various radiuses. Is there anywhere a simple example? My greatest problems seem to be in the embedding code. Gerhard -- Gerhard Kugler Bensheim

texdoc in ConTeXt standalone
by Henri Menke 04 Apr '18

04 Apr '18

Dear list, I'm sure you aware of the very useful "texdoc" command line utility in TeX live which brings up the PDF documentation for packages. ConTeXt standalone also comes with documentation in /opt/context/tex/texmf-context/doc/context However, I find it tedious to always search for the correct subfolder to get to the document I need. It would be great if there was something like mtxrun --script doc metafun which would open the MetaFun manual. Similarly "mtxrun --script doc gnuplot" would open the manual of the gnuplot module, etc. See attached for my shitty prototype. Cheers, Henri

margin of left/right floats
by Henning Hraban Ramm 04 Apr '18

04 Apr '18

Hello again, this should be a simple question, but I didn’t find anything (or probably didn’t look at the right places): How can I setup/change the margin beside a float (image) that is placed left or right?

BTX subsystem fubar, borked, failing with current (2018-04-02) beta
by Rik Kabel 04 Apr '18

04 Apr '18

MWE from page 4 of mkiv-publications (same example found at in the Garden <http://wiki.contextgarden.net/Bibliography_mkiv>) produces: with an empty bibliography. I get similar results with other documents that processed cleanly in the past. Has the documentation (including the sample code) simply failed to keep up with recent changes? -- Rik

entity substitution
by dr. Hans van der Meer 03 Apr '18

03 Apr '18

Does ConText always process DOCTYPE definitions? Because in the next example the defined XXX entity is substituted in one case but not in the other. In a directory I have the following files: doctype.tex = \startxmlsetups demo:setups \xmlsetsetup{#1}{root}{demo:*} \stopxmlsetups \xmlregistersetup{demo}{demo:setups} \startxmlsetups demo:root \xmlflush{#1} \stopxmlsetups \startbuffer[demo] <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE Entities [<!ENTITY XXX "My xxx definition">]> <root> See &XXX; for &XXX;. </root> \stopbuffer \starttext \xmlprocessbuffer{demo}{demo}{} \stoptext Produces as output a subtituted entity But doctype-public.tex = \startxmlsetups demo:setups \xmlsetsetup{#1}{root}{demo:*} \stopxmlsetups \xmlregistersetup{demo}{demo:setups} \startxmlsetups demo:root \xmlflush{#1} \stopxmlsetups \startbuffer[demo] <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE Entities PUBLIC "namen.dtd" "file://namen.dtd"><root> See &XXX; for &XXX;. </root> \stopbuffer \starttext \xmlprocessbuffer{demo}{demo}{} \stoptext namen.dtd = <!ENTITY XXX "This is my XXX definition"> The last two do not output a substituted entity. Why is this not working? What I am doing wrong? dr. Hans van der Meer

Strange behaviour of \start/stopplacefigure
by Tomas Hala 03 Apr '18

03 Apr '18

Hi, in the example below I came across the very strange behaviour of key location: if I use values none or top, the following paragraph is indented according to the settings whereas if I use the value bottom, the first line of the following paragraph starts just on the left, without any indentation. What am I doing wrong?
