\unit{mercury} renders as m (meter) and \unit{millimetermercury} doesn't work as expected
by Marco Patzer 05 Dec '23

05 Dec '23

Hi! I'm struggling with the rendering of a particular liquid metal: %% renders as m (meter), not as Hg \unit{mercury} %% renders as mm·m, not as mmHg \unit{millimetermercury} This is strange, since both “mercury” and “millimetermercury” are defined in phys-dim.lua. To get mercury recognised as a unit this can be used: \registerunitshortcut [mercury=mercury] Now \unit{mercury} renders correctly as Hg. Why is that \registerunitshortcut necessary? Is it even correct to use it like this? However, even then millimetermercury doesn't render correctly: %% renders as mm·Hg, not as mmHg \unit{millimetermercury} How to get millimetermercury render as mmHg? And “inch mercury” render as inHg? I can't find “inchmercury” in phys-dim.lua, only “millimetermercury”, should it be added? Example: %% \enabletrackers [physics.units] %% inch should render as “in” %% \setupunittext [inch=in] \starttext \unit{mercury}\crlf %% renders: mm · m \unit{12 millimetermercury}\crlf %% renders: mm · m \unit{12 inchmercury}\crlf %% renders: in · m %% why is this necessary to get mercury rendered as Hg? \registerunitshortcut [mercury=mercury] \unit{12 millimetermercury}\crlf %% renders: mm · Hg \unit{12 inch mercury}\crlf %% renders: in · Hg \stoptext Questions: 1) Why is \unit{mercury} not working, although it's listed in phys-dim.lua? 2) Is the call \registerunitshortcut [mercury=mercury] necessary/correct? 3) How to make \unit{millimetermercury} render as mmHg and \unit{inch mercury} render as inHg?

Colored Paragraph

Dear List, i have this example: \setupbodyfont[modern,10pt] \definemargindata [MyInMargin][inright] \definemarginframed[MyInMargin][topframe=on,bottomframe=on,rulethickness=1pt,width=1cm] \defineenumeration [theorem] [ text=Theorem, title=yes, width=fit, distance=0.5em, alternative=serried, ] \margintext{\blackrule[color=black, height=0.25ex, width=1cm]\\}\blackrule[color=black, height=0.25ex, width=15cm] \starttext \margintext {1.1.1} \startparagraph It was essential for Hasselt to have a bridge across the Zwarte Water river. The bishop of Utrecht gave Hasselt his consent in 1486. \blank Other cities in the neighbourhood of Hasselt were afraid of the toll money to be paid when crossing this bridge so they prevented the construction for many years. \stopparagraph \stoptext The paragraph should have a color in the background. How can I get an colored paragraph? Many thanks Uschi

Inline math spacing
by Alexandre Christe 04 Dec '23

Dear list, I’m facing some strange spacing with inline maths. Sometimes the space is ok (like around the first two fractions), but sometimes it is way too little. Do I miss to configure something? Thanks in advance, A. Christe

externalfigure regression?
by Thangalin 03 Dec '23

03 Dec '23

Hi, From the wiki <https://wiki.contextgarden.net/Command/externalfigure>: "When the file extension is .auto or method=auto is used, ConTeXt reads the first few bytes of the file to determine the filetype. Such an auto-discovery is useful for remote images that do not have a file extension." current version: 2023.09.26 18:19 Code: % SOT \starttext \startplacefigure \externalfigure[https://placekitten.com/408/287][method=auto] \stopplacefigure \stoptext % EOT Expected: Cute kitten photo. Actual: Error. Is this a regression? Or has the syntax changed (stale wiki)? Specifying the type works (I'd've thought it not necessary to specify the method at all, given both magic headers and HTTP content-type could determine the type): % SOT \starttext \startplacefigure \externalfigure[https://placekitten.com/408/287][method=jpg] \stopplacefigure \stoptext % EOT See also: https://gitlab.com/DaveJarvis/KeenWrite/-/blob/main/src/main/java/com/keenw… https://gitlab.com/DaveJarvis/KeenWrite/-/blob/main/src/main/java/com/keenw…

unwanted blank page
by Hans van der Meer 03 Dec '23

03 Dec '23

I should have a first page without pagenumber and pagenumbers on the subsequent ones. However the MWE here introduces an unwanted blank page from the call to \setuppagenumbering[state=start]. And the \setuppagenumbering has to come after the \page, of course. Should I program otherwise? yours sincerely dr. Hans van der Meer % test pagenumbering start-stop \setuppapersize[A5][A5] \starttext \setuppagenumbering[state=stop] \ConTeXt\space\contextversion\blank This is page 1 without pagenumber.\crlf \page \setuppagenumbering[state=start] This should be a page with pagenumber 2.\crlf But the pagenumber is 3 instead after blank page 2. \stoptext

mathalignment; alignment of columns
by wolfgangbackes＠mail.de 28 Nov '23

28 Nov '23

Something as elementary as "mathenvironment" can't really be faulty, can it? According to my recent tests, a mathalignment environment does not seem to react (any more) to the values of the "align" option. The source code hab been rendered correctly a few years ago, Minimal example 1: \starttext \startformula \startmathalignment[n=2,align={left, right}] \NC always aligned to the right \NC = u + at, \NR \NC d \NC = ut + \frac12 at^2. \NR \stopmathalignment \stopformula \stoptext Despite "align={left, right}", the first column is aligned to the right and the second to the left. This does not change, no matter which values I assign to "align", for example align={middle, middle}. The align option is also ignored in the case of other column numbers., for example: \starttext \startformula \startmathalignment[n=1,align=left] \NC This single column should \NR \NC be left-aligned, \NR \NC but it is centered. \NR \stopmathalignment \stopformula \stoptext What am I missing here? Where is my mistake? Regards Wolfgang

Converting XHTML captions to ConTeXt captions
by Thangalin 26 Nov '23

26 Nov '23

I'd like to capture a caption and apply it to the block-level element that immediately follows. In the MWE, is there a more "ConTeXt way" to accomplish the task of adding captions to tables, figures, blockquotes, etc? % SOT \startbuffer[demo] <body> <p><span class="caption">Caption 1 <a data-type="tbl" name="lbl-1"/></span></p> <table>table 1 with caption</table> <table>table 2 without caption</table> <p><span class="caption">Caption 3 <a data-type="tbl" name="lbl-2"/></span></p> <table>table 3 with caption</table> </body> \stopbuffer \startxmlsetups xml:demo \xmlsetsetup{\xmldocument}{*}{-} \xmlsetsetup{\xmldocument}{a|p|body|table}{xml:*} \xmlsetsetup{\xmldocument}{span[@class='caption']}{xml:span} \define\CaptionText{} \define\AnchorXref{} \stopxmlsetups \startxmlsetups xml:span \define\CaptionText{\xmlflush{#1}} \stopxmlsetups \startxmlsetups xml:a \define\AnchorXref{\xmlatt{#1}{data-type}-\xmlatt{#1}{name}} \stopxmlsetups \startxmlsetups xml:body \xmlflush{#1} \stopxmlsetups \startxmlsetups xml:p \xmlflush{#1}\par \stopxmlsetups \startxmlsetups xml:table \blank \doifelsetext{\CaptionText}{% \startplacetable[ title={\ignorespaces\CaptionText{}\removeunwantedspaces.}, reference={\AnchorXref} ] \define\CaptionText{} \define\AnchorXref{} }{ \startplacetable } \startembeddedxtable \startxtablebody[body] \startxrow \startxcell \xmlflush{#1} \stopxcell \stopxrow \stopxtablebody \stopembeddedxtable \stopplacetable \blank \stopxmlsetups \xmlregistersetup{xml:demo} \starttext \xmlprocessbuffer{demo}{demo}{} \stoptext % EOT
