SimpleSlides and Visual counters
by Otared Kavian 16 Jan '22

16 Jan '22

Hi all, in particular Aditya M. and Thomas A.S., It seems that the visual counter in SimpleSlides module (the version I have from ConTeXt Garden is from 2014) does not work fine with the latest LMTX. Is the issue is known ? If so, is there a new version of SimpleSlides in which the issue has been fixed ? Best regards: Otared

Changed behavior from \convertnumber{arabicdecimals}{..} as a textcommand for note
by musa furber 15 Jan '22

15 Jan '22

This week I updated ConTeXt minimals. Before then, I used the following code so that footnotes to Arabic passages would have parenthesis around them and use the digits used in Arabic texts in the Middle East (e.g. ٠١٢٣٤٥٦٧٨٩). \setupnote [arfootnote] [ headstyle={\switchtobodyfont[kitab]}, textcommand=\footnotenotenumbercommand, alternative=text, ] \define[1]\footnotenotenumbercommand{{\high{(\convertnumber{arabicdecimals}{#1})}}} Since the update, for the 123rd footnote, I now get `(123arabic)` instead of `(١٢٣)`. Elsewhere, I do get the expected output (i.e. `١٢٣٢`) when calling \convertnumber{arabicdecimals}{1232} I'm still relatively new to ConTeXt, so I'm unsure if what used really is correct, or if it was wrong and I now need to find the right way to do it. Any help would be greatly appreciated. —Musa

Itemize columns with MPgraphics: another vertical spacing puzzle
by Gavin 14 Jan '22

14 Jan '22

Hi List, I need to itemize graphics when I use those graphics as the choices in a multiple choice question. When I do that in columns, I am getting excess space below the graphics. See example code and output below. Any suggestions for how I get rid of this space? I’m not sure if this is related to the itemize column spacing in my previous comment. Thanks, again! Gavin \starttext \defineitemgroup[choices] \setupchoices [each] [A,joinedup] [left=(, right=), width=1.7em, stopper=,] \define\choice{\item} \def\mycolor{.625red} \startuseMPgraphic{name} fill fullcircle scaled 40pt withcolor \mycolor; \stopuseMPgraphic \define[1]\mycolordot{\def\mycolor{#1}\framed[location=top,offset=0pt,frame=off]{\useMPgraphic{name}}} What is your favorite color? (There is too much space after these choices.) \startchoices[columns,four] \choice \mycolordot{.625red} \choice \mycolordot{.625blue} \choice \mycolordot{.625green} \choice \mycolordot{.625magenta} \stopchoices A ruledhboxs show the extra space is in the itemize, but not in the item contents. \ruledhbox{\startchoices[columns, four] \choice \ruledhbox{\mycolordot{.625red}} \choice \mycolordot{.625blue} \choice \mycolordot{.625green} \choice \mycolordot{.625magenta} \stopchoices} Putting a ruledhbox around the first item shows that each item has extra space that is not part of the item contents. (The ruledhbox also messes with the horizontal alignment, but I don't care about that.) \startchoices[columns] \ruledhbox{\choice \mycolordot{.625red}} \choice \mycolordot{.625blue} \choice \mycolordot{.625green} \choice \mycolordot{.625magenta} \stopchoices The extra space is not present without columns. \startchoices \choice \mycolordot{.625red} \choice \mycolordot{.625blue} \choice \mycolordot{.625green} \choice \mycolordot{.625magenta} \stopchoices \ruledhbox{My favorite color is:\def\mycolor{.625blue} \framed[location=top,offset=0pt,frame=on] {\useMPgraphic{name}}} \stoptext

Spacing issue in itemize
by Gavin 14 Jan '22

14 Jan '22

Hi list, When I define an items group, it seems to mess up the spacing for a nested item group. See example below. Any ideas? I’m typesetting with > ConTeXt ver: 2022.01.06 19:51 LMTX fmt: 2022.1.9 int: english/english on an M1 Mac. Thanks! Gavin \usemodule[visual] \defineitemgroup[questions] \setupquestions [each] [n] \starttext This numbered list uses my item group \quotation{questions.} The itemize inside is missing space above item (a). \startquestions \item \fakewords{15}{20} \startitemize[a][left=(,stopper=,right=)] \item \fakewords{10}{15} \item \fakewords{10}{15} \stopitemize \item \fakewords{10}{15} \stopquestions This numbered list uses itemize.

process markdown file
by J Huisman 14 Jan '22

14 Jan '22

Hi all, I have updated to the latest version and it seems that the MarkDown module is no longer part of the context installation. I get an 'undefined control sequence' error for \processmarkdownfile and the module files are gone. Is this on purpose? Why has it been removed? Can this please be restored? MWE \usemodule[markdown] \starttext \processmarkdownfile{file.md} \stoptext Manual solution: I have found the files 'm-markdown.lua' and 'm-markdown.mkiv' but I am not sure where/how to install them? Thanks, Jelle

clartype typescript
by Youssef Cherem 14 Jan '22

14 Jan '22

Hello everyone, I'm a new Context user, so pardon me if it's obvious. I found the cleartype typescript, but can't figure out how to use it. I thought it would be as easy as: \usetypescript[cleartype] But I am confused as to what to put in \setupbodyfont[?] (there are several sans fonts to choose from).

\setupheadertexts not working when text contains \subject
by Bruce Horrocks 14 Jan '22

14 Jan '22

I've found an unexpected interaction between \setupheadertexts and the \subject command, and I'm hoping that someone can tell me what I'm doing wrong. Version: current version: 2022.01.10 08:36 I'm trying to set a book whereby - chapter title pages have no headers - left hand (even) pages have the chapter title in the left header and the book title in the right header - right hand (odd) pages have the book title in the left header and the author's name in the right header The following MWE does this perfectly provided the \subject line is commented-out. When the \subject line is included then the author name disappears - there's just a blank space in the header. MWE: \setuppagenumbering [ alternative=doublesided, location={footer}, ] \definefont [stylePageHeader] [Serif at 10pt] \startsetups ChapterSetup \setupheadertexts [{\stylePageHeader {My Book}}] [{\stylePageHeader{\structureuservariable{author}}}] [{\stylePageHeader{\getmarking[Chapter]}}] [{\stylePageHeader {My Book}}] \setupheader[state=empty] \stopsetups \definehead [Chapter] [chapter] \setuphead[Chapter] [ page=right, number=no, before={\setups{ChapterSetup}}, ] \starttext \startChapter[title={The Strange Case of the Missing Header}] [author={Bruce}] \dorecurse{10}{ %\subject{A heading} \input Knuth \par } \stopChapter \stoptext — Bruce Horrocks Hampshire, UK

MetaFun: textext.origin, thelabel.origin not positioned on baseline
by Gavin 13 Jan '22

13 Jan '22

Hello again List, Now I’m making diagrams using MetaFun. The MetaFun manual describes an “origin” option for positioning textext’s and label’s on the baseline. However, this dose not appear to be happening with the code in the manual (below). In fact, the diagram in the manual dose not show the textext’s and label’s on the baseline. This is on page 144 of metafun-p.pdf. Maybe I misunderstand what is supposed to be happening here. Thanks! Gavin \startMPcode picture p ; p := \MPbetex {1} ; picture q ; q := textext.origin( \MPstring{2} ) ; picture r ; r := thelabel.origin("\MPtext {3}",origin) ; for i=p, boundingbox p : draw i withcolor .625red ; endfor ; for i=q, boundingbox q : draw i withcolor .625yellow ; endfor ; for i=r, boundingbox r : draw i withcolor .625white ; endfor ; currentpicture := currentpicture scaled 2 ; draw origin withpen pencircle scaled 5.0mm withcolor white ; draw origin withpen pencircle scaled 2.5mm withcolor black ; draw boundingbox currentpicture withpen pencircle scaled .1mm dashed evenly ; \stopMPcode

Placement of floats
by Willi Egger 13 Jan '22

13 Jan '22

Hi all, here follows the compilation of the example-file, this time I replaced the dummy-figure with a simple \framedtext in order to comply with the 100kB rule of the mailing-list. I added a black line at the bottom with “Preview” on Mac OSX , so the problem is visible immediately. Kind regards Willi

\sub conflict with my def
by Gavin 13 Jan '22

13 Jan '22

Hi List, I am converting problem sets from LaTeX to ConTeXt and ran into a puzzling problem. I define \sub to produce subscript text in math mode. (See definition below.) This worked for my ConTeXt book, but fails in the problem sets because in ConTeXt \sub is a special item command, and I use itemize to number problems. Obviously, I can rename my \sub command, but it is already used in hundreds of problems and solutions that I am converting. Is there a way to get my \sub to work in an itemize? I only need it in math mode. I will never use \sub for its ConTeXt itemizing purpose. Thanks! Gavin \define[1]\sub{_{\text{\rm\tf#1}}} \starttext $E\sub{final}$ is the final energy, but not in an itemize: \startitemize \item $E_{\text{\rm final}}$ is the final energy. \item $E\sub{final}$ is a mess. \stopitemize \stoptext
