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

Wiki: new commands not automatically available for autogenerated syntax (was LTR footnotes from RTL paragraph)
by denis.maier＠unibe.ch 13 Jan '22

13 Jan '22

Hi, I wanted to wikify a new command, but I don't fully understand what to do... > -----Ursprüngliche Nachricht----- > Von: Hans Hagen <j.hagen(a)xs4all.nl> > Gesendet: Donnerstag, 13.

And, the new option for \setupalign does not show up in the autogenerated syntax overview at https://wiki.contextgarden.net/Command/setupalign I probably don't fully understand how the wiki works in these regards .. can anyone clarify?

Conditional text appearing in a fixed vertical space
by Gavin 12 Jan '22

12 Jan '22

Hello List, I am making problem sets for a physics class. Solutions use the style defined in the example below, and only appear if the “solution” mode is enabled. I am struggling to get a vertical space for the solution which is the same whether or not the solution is printed. Different problems require different amounts of space, so this should be an argument or key-value. In the example below, the first solution has the desired behavior. The second solution has the syntax I’d like, but it doesn’t make the space without a solution. Any ideas would be welcome! I am still pretty new to ConTeXt, so I struggle mixing things like the plain tex \vbox and ConTeXt \start…\stop concepts. Thanks, Gavin \definemode[solution][yes] % yes to enable solutions, no to disable \definebuffer [solution] % Captures solution in a buffer that isn't used \startmode[solution] % If in solution mode, redefine \startsolution...\stopsolution \definedelimitedtext[solution][ % Solution italic and indented spacebefore=medium, spaceafter=medium, style=\rm\it, leftmargin=standard, % Indents block on the left rightmargin=yes, % Indents block on the right indentnext=no, before=\vbox to 1in\bgroup, after=\egroup, ] \stopmode \starttext How many roads? (The 1-inch space below appears whether or not it contains a solution.) \vbox to 1in{% \startsolution 42 roads. \stopsolution } How much wood? (I would like to define solution so this to behaves like the previous question.) \startsolution[1in] Alotta wood! \stopsolution No more questions. \stoptext

LTR footnotes from RTL paragraph
by denis.maier＠unibe.ch 12 Jan '22

12 Jan '22

Hi Footnotes originating from an RTL paragraph will be also typeset in RTL mode as the following example illustrates: %%%%%%%%%%%%%%%%%%%%%% \setupdelimitedtext[blockquote] [leftmargin=1.5em,rightmargin=0em,] \definedelimitedtext[rtlblockquote] \setupdelimitedtext[rtlblockquote] [leftmargin=0em,rightmargin=1.5em,before={\righttoleft}] \starttext \input knuth \startblockquote \input knuth\footnote{this starts on the left.} \stopblockquote \startrtlblockquote \input knuth\footnote{this should start on the left, but it doesn't.} \stoprtlblockquote \input knuth \stoptext %%%%%%%%%%%%%%%%%%%%%%%% According to the wiki, that's the expected behaviour (https://wiki.contextgarden.net/RTL#Footnotes) However, I'd prefer to keep the footnotes as LTR footnotes. Can I convince ConTeXt to typeset these footnotes in LTR mode? Best, Denis
