Ignored spacings are ignored
by Henri Menke 18 Mar '20

18 Mar '20

Dear list, Sorry for the stupid title, I couldn't resist. :-) LuaTeX has the option to adjust spacing between different classes of math atoms. However, looking in the TeXbook, page 170, in the table for spacings between adjacent atoms, we find that some of those spacing are undefined (* in the table) and therefore, when TeX encounters this combination, spacing is just skipped. This also translates to the parameters in LuaTeX. For example the combination Open-Bin is skipped by TeX and therefore setting the corresponding parameter just does nothing. \Umathordrelspacing\textstyle=50mu \Umathopenbinspacing\textstyle=50mu $a = (-2)$ \bye So my question is, what is the point of the parameters that describe these skipped combinations? Shouldn't they just be deleted? Alternatively, they could actually be implemented to do something. More context: https://tex.stackexchange.com/questions/532758 Kind regards, Henri

Exercise file with statements and correction
by Fabrice Couvreur 17 Mar '20

17 Mar '20

Hello, I would like to make files with statements of exercises and correction where it would be enough to click on "correction" to access the correction at the end of the file. I'm running out of time, does anyone have a model to share ? Thank you so much. Fabrice

Issue with rendering arrows in lmtx
by Jan-Erik Hägglöf 17 Mar '20

Hi All! When I invoke this command \startMPcode picture p ; p := lmt_svg [ filename ="pil.svg" ]; draw p; \stopMPcode I get weird results, the arrowhead points in wrong direction and is very tiny compared to the size it was meant to have. Here is the .svg code from the saved file (pil.svg) made in Inkscape 0.92 for Mac OS <?xml version="1.0" encoding="UTF-8" standalone="no"?> <svg xmlns:dc="http://purl.org/dc/elements/1.1/" xmlns:cc="http://creativecommons.org/ns#" xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#" xmlns:svg="http://www.w3.org/2000/svg" xmlns="http://www.w3.org/2000/svg" xmlns:sodipodi="http://sodipodi.sourceforge.net/DTD/sodipodi-0.dtd" xmlns:inkscape="http://www.inkscape.org/namespaces/inkscape" inkscape:version="1.0beta2 (2b71d25, 2019-12-03)" id="svg8" version="1.1" viewBox="0 0 462.85062 100.67344" height="100.67344mm" width="462.85062mm" sodipodi:docname="pil.svg"> <defs id="defs2"> <marker inkscape:stockid="Arrow2Lend" orient="auto" refY="0" refX="0" id="Arrow2Lend" style="overflow:visible" inkscape:isstock="true"> <path id="path853" style="fill:#000000;fill-opacity:1;fill-rule:evenodd;stroke:#000000;stroke-width:0.625;stroke-linejoin:round;stroke-opacity:1" d="M 8.7185878,4.0337352 -2.2072895,0.01601326 8.7185884,-4.0017078 c -1.7454984,2.3720609 -1.7354408,5.6174519 -6e-7,8.035443 z" transform="matrix(-1.1,0,0,-1.1,-1.1,0)" inkscape:connector-curvature="0" /> </marker> <marker inkscape:stockid="Arrow1Send" orient="auto" refY="0" refX="0" id="Arrow1Send" style="overflow:visible" inkscape:isstock="true"> <path id="path847" d="M 0,0 5,-5 -12.5,0 5,5 Z" style="fill:#000000;fill-opacity:1;fill-rule:evenodd;stroke:#000000;stroke-width:1pt;stroke-opacity:1" transform="matrix(-0.2,0,0,-0.2,-1.2,0)" inkscape:connector-curvature="0" /> </marker> <marker inkscape:stockid="Arrow1Mstart" orient="auto" refY="0" refX="0" id="Arrow1Mstart" style="overflow:visible" inkscape:isstock="true"> <path id="path838" d="M 0,0 5,-5 -12.5,0 5,5 Z" style="fill:#000000;fill-opacity:1;fill-rule:evenodd;stroke:#000000;stroke-width:1pt;stroke-opacity:1" transform="matrix(0.4,0,0,0.4,4,0)" inkscape:connector-curvature="0" /> </marker> </defs> <sodipodi:namedview showgrid="false" inkscape:document-rotation="0" inkscape:current-layer="layer1" inkscape:document-units="px" inkscape:cy="-33.787703" inkscape:cx="722.89047" inkscape:zoom="0.35" inkscape:pageshadow="2" inkscape:pageopacity="0.0" borderopacity="1.0" bordercolor="#666666" pagecolor="#ffffff" id="base" inkscape:window-width="1440" inkscape:window-height="804" inkscape:window-x="0" inkscape:window-y="23" inkscape:window-maximized="0" /> <metadata id="metadata5"> <rdf:RDF> <cc:Work rdf:about=""> <dc:format>image/svg+xml</dc:format> <dc:type rdf:resource="http://purl.org/dc/dcmitype/StillImage" /> <dc:title></dc:title> </cc:Work> </rdf:RDF> </metadata> <g id="layer1" inkscape:groupmode="layer" inkscape:label="Lager 1" transform="translate(141.37191,110.50081)"> <path style="fill:#000000;fill-opacity:1;stroke:#000000;stroke-width:3.565;stroke-linecap:butt;stroke-linejoin:miter;stroke-miterlimit:4;stroke-dasharray:none;stroke-opacity:1;marker-end:url(#Arrow2Lend)" d="m -141.36309,-96.761905 458.10714,2.267858" id="path830" inkscape:connector-curvature="0" /> </g> </svg> Is there som incompatibility issues with reading those files?

Hi, With the Coronavirus pandemic, my school will close like all the others. We chose to work with Microsoft Teams. I know how to file Math exercises written with ConteXt and export to pdf format. Is it possible with ConteXt to create interactive Quizz? Thank you Fabrice

(bug?) wrong interline in \placelist[alternative=d] with Pagella italics
by Pablo Rodriguez 16 Mar '20

16 Mar '20

Hi Hans, here you have the sample: \setuppapersize[A6] \setupinteraction[state=start] \enabledirectives[references.border] \setupbodyfont[pagella] \starttext \placelist[section] [alternative=d, style=\it] \section{Section 1} \section{\dorecurse{25}{Section }3} \section{Section 3} \stoptext For some strange reason (at least, to me), \placelist[alternative=d] seems to misbehave when using \it or \bi as style. Everthing is fine when italic fonts aren’t used. I’m afraid I may be hitting a bug in both latest MkXL from 2020.03.10 14:52 and MkIV from 2019.07.24 11:31. Many thanks for your help, Pablo -- http://www.ousia.tk
