Problem with \startlinenumbering left and right arguments
by Marcus Vinicius Mesquita 09 Dec '23

09 Dec '23

Dear List, In the MWE below, the left and right arguments are not applied in the last chapter. How can this be fixed? \starttext \startlinenumbering[left={[},right={]}] \dorecurse{5}{% \startchapter[title={Knuth}] \samplefile{knuth} \stopchapter } \stoplinenumbering \stoptext Kind regards Marcus Vinicius -- Todas as coisas fatigam o corpo, salvo a música, que não fatiga nem o corpo nem seus membros, por ser descanso da alma, primavera do coração, distração do aflito, entretenimento do solitário, e viático do viajante.

\placefigure[location=here...] problem
by anton.chigurh＠mail.com 09 Dec '23

09 Dec '23

Hi all, I am generating a quiz, with eight questions, each with text and a figure following it. The output was fine till the fifth question, but then the margin separating the text of each question disappeared and the figure got put on the next page one after the other. Can anyone suggest what I could be doing wrong? Do I need to increase the buffer? how? This is what I have used to place each figure \startplacefigure[location=here,reference=fig:blah][]{} \externalfigure[blah.jpeg][scale=300] \stopplacefigure

ConTeXt support for Nova text editor (MacOS)
by Paul Mazaitis 09 Dec '23

09 Dec '23

Hello, list! I'm working on a ConTeXt language extension for the Nova editor by Panic software (https://nova.app/) The extension is here: https://github.com/pmazaitis/nova-context/releases/tag/0.6.0 ...currently in beta, but fairly functional. This version of the extension supports: * Syntax Highlighting * Folding for (most) environments * Navigating by Symbols (headings: chapter, section, etc.) * Spell-checking of body text and section titles * Managing builds with Nova's tasks system (As an aside, this extension uses an updated version of the ConTeXt tree-sitter parser [https://github.com/pmazaitis/tree-sitter-context] that can now recognize (most) environments and use them to parse out the document hierarchy.) Limitations at the moment: not all environments are supported (only those with \start and \stop commands right now), and the extension only supports English. Happy for any bug reports, etc., -Paul

mtx-synctex.lua question
by Jim 08 Dec '23

08 Dec '23

Hi, In mtx-synctex.lua, inside local function findlocation(filename,page,xpos,ypos,tolerance) there is the following code: for s=1,tolerance,max(tolerance//10,1) do locate( s, 0) if fi ~= 0 then tl = s ; goto done end locate(-s, 0) if fi ~= 0 then tl = s ; goto done end locate( s, s) if fi ~= 0 then tl = s ; goto done end locate( s,-s) if fi ~= 0 then tl = s ; goto done end locate(-s, s) if fi ~= 0 then tl = s ; goto done end locate(-s,-s) if fi ~= 0 then tl = s ; goto done end end Is the omission of the locate(0, s) ... and locate(0, -s) ... cases intentional, or is that an oversight? If intentional, can someone explain the rationale to me? Thanks. Jim

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
