start/stop executed conditionally on mode ?
by Fabrice L 15 Jun '20

15 Jun '20

Dear List, I would like to insert a page using (ideally) start/stop instructions. The problem is that this page should be inserted only in a certain mode. Consulting the mailing list, I thought the following code was working, but it’s not ! The code is executed in the mode as expected, but the following instructions ("Some other text... » in the exemple) is not typeset. Here is a minimal (not working!) example: % ———————————————————————————————————— \unexpanded\def\StartQuestionsList{ \startmode[ClassRoom] \page[yes] Here are some questions: \blank } \unexpanded\def\StopQuestionsList{ \page[yes] \stopmode } \definestartstop[Questions][ before=\StartQuestionsList, after=\StopQuestionsList ] \startQuestions Question A…. Question B…. \stopQuestions Some other text... % ———————————————————————————————————— So to be clear, I would like the result in the « ClassRoom » mode to be: % ———————————————————————————————————— Here are some questions: Question A…. Question B…. Some other text... % ———————————————————————————————————— Otherwise to be: % ———————————————————————————————————— Some other text... % ———————————————————————————————————— Thanks for any help ! Fabrice.

\recursestring undefined when inside \dorecurse
by Pablo Rodriguez 14 Jun '20

14 Jun '20

Dear list, I have the following sample: \starttext \dorecurse{25}{\recurselevel\par} \doloopoverstring{a,b,c}{\recursestring} } \stoptext Both LMTX and MkIV complain about \recursestring for being undefined. I wonder whether this is inteded or it is a bug. Many thanks for your help, Pablo -- http://www.ousia.tk

using annotations for extended print handling
by Pablo Rodriguez 14 Jun '20

14 Jun '20

Dear list, I have an over a thousand pages document generated with ConTeXt. I need to print and chapters and part of chapters (or send to other people). /PrintPageRange is great (and you can even generate a new document containing only the pages in /PrintPageRange). But the issue here is that I would need to recompile the document again for each new required /PrintPageRange. Another approach would be to add PDF annotations (outside page boundaries) to store the desired information. So I created text annotations (using \comment) with author information composed from unit number (such as "i3", "ii9" or "iii28"), info on the unit part (such as "-explanation", "-synopsis", "-exercises", or others) and position ("-start" and "-stop"). This would make author fields such as "i3-start" (which has a corresponding "i3-stop", or "ii22-synopsis-start" (with the corresponding closing annotation). To make easier to identify these annotations, they all share the same title. As contents, all these text annotations have the page number. From the generated PDF document, I need to read all text annotations in order to extract two fields from those annotations that contain a "whatever" /Subj. These fields are /T and /Contents. I guess that the way to deal with the (over 700) annotations would be to store both fields in a Lua table. But this is only a suspicion, since I don’t know how to read the values, how to store them, or how to compare them with specific units or unit parts to get these page numbers. I mean, with a command such as \extractpages{i5,i8-exercises,i15-explanation} would get the pages for each "-start" and "-stop" that could be passed automatically to a \filterpages command. A sample that generates something similar: \setuppapersize[A8] \setupinteraction[state=start] \starttext \dorecurse{5}{\part{\romannumerals{\recurselevel}} \dorecurse{15}{\chapter{\recurselevel} \comment [title=whatever, color=yellow, %~ the following code is to have expansion in interaction author={\ctxlua{context([[\namedstructurevariable{part}{title}% \namedstructurevariable{chapter}{title}]].."-start")}}] {\pagenumber} \doloopoverlist{explanation,exercises,synopsis}{\chapter{\recurselevel} %~ I would like to use \recursestring, but it is undefined here \comment [title=whatever, color=green, author={\ctxlua{context([[\namedstructurevariable{part}{title}% \namedstructurevariable{chapter}{title}]].. [[-\recurselevel]].."-start")}}] {\pagenumber} \dorecurse{5}{\null\page} \comment [title=whatever, color=blue, author={\ctxlua{context([[\namedstructurevariable{part}{title}% \namedstructurevariable{chapter}{title}]].. [[-\recurselevel]].."-stop")}}] {\pagenumber} } \comment [title=whatever, color=red, author={\ctxlua{context([[\namedstructurevariable{part}{title}% \namedstructurevariable{chapter}{title}]].."-stop")}}] {\pagenumber} } } \stoptext Is there a way to deal with the annotations in the document generated from the code above, in the way I described before? Many thanks for your help, Pablo -- http://www.ousia.tk

Problem with Hello-World.tex
by Alessandro Perucchi 14 Jun '20

14 Jun '20

Hello everyone, I am quite new to ConTEXt, and after installed it according to the following web page : https://wiki.contextgarden.net/Installation <https://wiki.contextgarden.net/Installation> I’ve installed it in macOS Catalina 10.15.5. After a successful installation (I hope), I tried to run the “First Run!” part, so I’ve downloaded the file Hello-World.tex file (via wget), and I’ve run the command “context Hello-World.tex”. I’ve attached the resulting PDF, and it looks great, except for one part, which is the figure and the text flowing around it, which is not the case here. Is there something wrong in what I’ve done? I mean, I’ve done a fresh installation, download of Hello-World.tex and run the context command. Here are the version that I could find: ➜ ~ context --version mtx-context | ConTeXt Process Management 1.03 mtx-context | mtx-context | main context file: /Users/lg/Context/tex/texmf-context/tex/context/base/mkiv/context.mkiv mtx-context | current version: 2020.06.12 17:43 mtx-context | main context file: /Users/lg/Context/tex/texmf-context/tex/context/base/mkiv/context.mkxl mtx-context | current version: 2020.06.12 17:43 Thank you!

Wrong page numbers in frontmatter
by Jack Steyn 14 Jun '20

14 Jun '20

Hi, I'm not sure why the following MWE produces a document where page 2 has the page number i instead of ii. It seems to have something to do with the use of makeup. I was using it to create a vertically centered title page. Is there a better way of doing this which will give the correct page numbers? Best, Jack \definestructureconversionset[frontpart:pagenumber][][romannumerals] \definestructureconversionset[bodypart:pagenumber][][numbers] \definemakeup[titlepage][align=middle] \starttext \startfrontmatter \startmakeup[titlepage] Title \stopmakeup test \stopfrontmatter \startbodymatter \setcounter[userpage][1] test \stopbodymatter \stoptext

\the\font in luametatex
by Marcel Fabian Krüger 13 Jun '20

13 Jun '20

Hi, in the latest luametatex version, \the\font does ... something weird: E.g. with a current, fully updated lmtx, I get for \starttext \showthe\font \stoptext the output > }\ifempty \currentstyleparameter \else \dousecurrentstyleparameter \fi instead of the expected > \3>modern-designsize-12pt-rm-tf-0--0 (or similar) (given that this contains an unmatched `}`, it causes havoc if \the\font is used in unsuspecting macro code.) Best regards, Marcel

Asymptote and lmtx
by Otared Kavian 13 Jun '20

13 Jun '20

Hi all, Recently I have been using (in a very elementary way) Metafun in order to visualize a small set of data in 2 dimensions, as a scattered set of labeled dots, and I wanted to do the same in 3 dimensions. Indeed one can write an analogous Metafun code for 3d, but I thought using Asymptote is more efficient. I saw that there is a module m-asymptote.mkiv in the distribution, but typesetting that file with lmtx or mkiv does not give the expected result. Has anyone a working example of using Asymptote from within ConTeXt, from which I could begin to learn? Thanks for any hint: Otared

Extra space when \setcharacterkerning is used in enumeration
by Mikael Sundqvist 12 Jun '20

12 Jun '20

Hi, I noticed an extra space in an enumeration when using \setcharacterkerning in the \headstyle parameter. The extra space appears before the first word "Sats", and in my case it is unwanted (In the example I want the word Sats to align with a), b), ...). The space was not there a year ago, with the same code. In the test file below (sorry for its length), the environment sats is having the problem, while SATS does not. The only difference is in the \headstyle parameter. Am I missing something obvious? /Mikael PS I use the version of today, where the curious problems with sizes inside square roots and fractions seem to be gone. %%%%%%%%% Testfile starts here \setupbodyfont[stixtwo,10bp] \definemeasure[myitemwidth][26bp] \definemeasure[myindent][12bp] \setupindenting[yes,\measure{myindent}] \definecharacterkerning[sats][factor=0.1] \define[1]\vakuum{\hskip\measure{myindent}#1.} \defineenumeration[sats][ text={Sats}, style={\em}, title=yes, titlestyle=, width=fit, headstyle={\smallcaps\setcharacterkerning[sats]}, headcommand={\vakuum}, number=yes, alternative=serried, indenting={yes,\measure{myindent}}, ] \defineenumeration[SATS][sats][ headstyle=\smallcaps,%It is this setting that kills the space. ] \defineitemgroup[delab] \setupitemgroup[delab][each][a,intro,intext][ stopper=, right=), left={\hskip\measure{myindent}}, width=\measure{myitemwidth}, inbetween=, before={\blank[none,samepage]}, after=, style={\tf}, ] \starttext \startTEXpage[offset=3bp] \samplefile{ward} \startsats[title={Räkneregler för gränsvärden}] Antag att $c$ är ett tal, och att $a_k\to A$ och $b_k\to B$ då $k\to+\infty$.

Changed behavior of ^^ in csname
by Marcel Fabian Krüger 12 Jun '20

12 Jun '20

Hi, I noticed that in the latest LMTX version, ^^ (with ^ of catcode 7) is no longer interpreted inside csnames. Is this intentional? (Example: \starttext \catcode\circumflexasciicode=\superscriptcatcode% Ensure correct catcodes \show ^^41 % This still works and shows "> the letter A" \show^^41 % This used to be an error "Undefined control sequence \showA", % now show "> The letter A" \show\^^41 % Used to show "> \A=undefined", now shows "> \^=macro:->\enco_handle_accent {^}" % and "! Missing $ inserted" \stoptext ) Best regards, Marcel
