Buffer and \input content as input for \processtokens, etc.
by Jairo A. del Rio 06 Dec '23

06 Dec '23

Hi, list! My question is just like that: how do I pass buffers or \input content to \processtokens. What I have done so far: \tolerant\protected\def\foo#={\ifparameter#1\or\oof{#1}\fi} \protected\def\oof#1{<#1>} \startbuffer[ofo] % Output: Th<i>s <is> not a <question> anymore! Th{i{s {is} not a {question} anymore! \stopbuffer \starttext \processtokens\foo\foo\relax\space{Th{i}s {is} not a {question} anymore!} % Neither \inlinebuffer nor \rawbuffer work in the example above \stoptext I've also tried a variant of the mechanism described in OPmac trick described here <https://petr.olsak.net/opmac-tricks-e.html#etoks> to process content token by token, but it only works with \normalinput. Any suggestions or guidance? Thank you in advance. Best regards, Jairo

(again) wrong destination types?
by Pablo Rodriguez 06 Dec '23

06 Dec '23

Dear list, sorry for insisting, but this is important for my documents. I have the following sample: \setupinteraction[state=start, page=name, focus=standard] \starttext a\footnote{b} \stoptext If page is set to anything different than no in \setupinteractionscreen, focus=standard will not work (it will be used as focus=fit). Could anyone confirm the issue or explain me what I’m doing wrong? Many thanks for your help Pablo

framed: rounded corner oddity
by Henning Hraban Ramm 05 Dec '23

05 Dec '23

Hi, in my ConTeXt book, some examples for \framed with rounded corners look odd, as if the MetaPost calculation of rounded corners fails. I can’t find a minimal example that shows the problem, and I can’t imagine which of the settings in my extensive environment would cause it. Find below the code that works on its own, but causes the results as shown in the attachments within my book. There’s nowhere a \setupframed, and nothing that should influence MetaPost. Do you have any clue for what I should look? Hraban \starttext \framed[ rulethickness=1pt, offset=0.5em, background=color, backgroundcolor=yellow, framecorner=13, backgroundcorner=07, backgroundoffset=0.5em, ]{Das Runde muss ins Eckige} \blank \framed[ frame=on, corner=round, frameoffset=0.5em, framecolor=black, background=color, backgroundcolor=darkgreen, backgroundoffset=1em, foregroundcolor=white, foregroundstyle={\ss\bf}, ]{Komm ins Grüne!} \stoptext

\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
by Ursula Hermann 05 Dec '23

05 Dec '23

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

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 04 Dec '23

04 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…

I would like to change the width of the margins on the page. In the MWE here, the pagelayout does not seem to obey the \setuplayout command. Why are the margins shown uneffected by \setuplayout? yours sincerely dr. Hans van der Meer

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
