background= key not working in \startbackground and \starttextbackground
by Aditya Mahajan 06 Jun '24

06 Jun '24

Hi, I am testing some of my old styles on latest context and find that the background key of \startbackground and \starttextbackground doesn't work (\framed is working as expected). Here is a MWE: \startuseMPgraphic{background:test} fill OverlayBox withcolor 0.75[red,white]; draw OverlayBox withcolor red withpen pencircle scaled 2bp; \stopuseMPgraphic \defineoverlay[background:test][\useMPgraphic{background:test}] \definetextbackground [testA] [ location=paragraph, background=background:test, frame=off, ] \definebackground [testB] [ location=paragraph, background=background:test, frame=off, ] \defineframedtext [testC] [ background=background:test, frame=off, width=broad, ] \starttext \starttestA \input tufte \stoptestA \starttestB \input tufte \stoptestB \starttestC \input tufte \stoptestC \stoptext testA gives nothing, testB gives a gray(!) background, and testC works as expected. The output is attached. I am using 2024.05.31. Aditya

Kerning in Noto Serif
by Lutz Haseloff 06 Jun '24

06 Jun '24

Hi all, I can't get Kerning working with Noto Serif. My minimal file is: \definefontfeature[oldstylenumber][onum=yes] \definefont[testnoto][file:NotoSerif-Regular*default at 12pt] \starttext Line 1: {VAVAVAVAVAVA 12345}\par Line 2: {\setff{oldstylenumber}VAVAVAVAVAVA 12345}\par Line 3: {\addff{oldstylenumber}VAVAVAVAVAVA 12345}\par \testnoto Line 4: {VAVAVAVAVAVA 12345}\par Line 5: {\setff{oldstylenumber}VAVAVAVAVAVA 12345}\par Line 6: {\addff{oldstylenumber}VAVAVAVAVAVA 12345}\par \stoptext Line 4 and 6 should be significantly shorter too. I tried the variable and the static versions. In fontforge I can see a kerning of -80 between A and V. My context is the newest lmtx. Greetings Lutz

\item would fit, but was pushed to next page. Work-around or fix?
by Jim 06 Jun '24

06 Jun '24

Hi, I had the following structure which ended up at the bottom of a page: ----------------------------------------------------------------------- \setupcaptions[number=no] \placefigure[right] {blah blah blah} {% \vskip -15pt \externalfigure[DSC_2782][width=0.32\textwidth] } \noindent {\bf Blah blah blah } \startitemize[intro,nowhite] \item blah blah blah blah blah blah! blah blah blah blah, blah blah blah blah blah blah blah blah blah blah. \item blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah. \item blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah. \item blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah. \item blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah. \item blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah. \stopitemize -------------------------------------------- There was, in fact, room to put the last \item on the page (and even a bit more), but ConTeXt insisted on moving the last \item to the next page. I assume that its calculations were a bit conservative for whatever reason, but I really wanted the last item to be on the same page as its friends. I tried some "tricks" that would have worked for me in plain TeX, but ConTeXt was having none of that. Q1: Is there a Right Way to force ConTeXt to put an \item on the current page? Q2: If not, does anyone wish to suggest some way to trick ConTeXt here, or to do an end-run around its calculations? Note: to solve this problem the use of brute force has been authorized. Thanks.

setuphead in connection with the command argument
by Gerion Entrup 06 Jun '24

06 Jun '24

Hi, I'm trying to adapt the format of chapters in my document and have a few questions regarding setuphead. My aim is to have the chapter (title) on a separate page with an additional intro in different text sizes for title, subtitle and the intro. I chose to use the "command=" argument in setuphead for that. However, I'm not quite sure about it's internals. Let's begin with a minimal example: ``` \define[2]\MyChapter{% #1 #2: \structureuservariable{subtitle} (\structureuservariable{intro}) } \setuphead[title, chapter][command=\MyChapter] \setupbodyfont[11pt] \starttext \startchapter[title=foo][subtitle=bar, intro={some explanation}] some text \stopchapter \stoptext ``` This produces 1.pdf. ## Font size What is the reason that that the font of the chapter is bigger? How can I reset it to normal size? This does not work at all: ``` \define[2]\MyChapter{% \setupbodyfont[11pt] #1 #2: \structureuservariable{subtitle} (\structureuservariable{intro}) } ``` However, changing to a bigger font works somehow. Is there a factor applied to the font size internally? For example: ``` \define[2]\MyChapter{% \setupbodyfont[20pt] #1 #2: \structureuservariable{subtitle} (\structureuservariable{intro}) } ``` produces 2.pdf (the chapter font is not 20pt). ## Line breaks How can I achieve line breaks? This does not work: ``` \define[2]\MyChapter{% #1 #2:\\ \structureuservariable{subtitle}\\ (\structureuservariable{intro}) } ``` (see 3.pdf) I also want to set everything except of the intro in a flushright environment but do not know how. I tried: ``` \define[2]\MyChapter{% \startalignment[flushright] #1 #2:\\ \structureuservariable{subtitle}\\ \stopalignment \structureuservariable{intro} } ``` (see 4.pdf, no change) ## Bold text I tried to get the text bold. However, `#1` and `#2` does not seem to follow this. ``` \define[2]\MyChapter{% \bold #1 #2: \structureuservariable{subtitle} (\structureuservariable{intro}) } ``` ## Makeups The best solution, I had so far, was to define a makeup, but I don't get it to work with text with mixed alignment and it does not solve the font size problem: ``` \definemakeup[chapter][align=left, top=] \define[2]\MyChapter{% \startmakeup[chapter] #1 #2:\\ \structureuservariable{subtitle}\\ \stopmakeup (\structureuservariable{intro}) } ``` (see 5.pdf) ## Framed I also have tried this but it does not bring any linebreaks: ``` \define[2]\MyChapter{% \framed[frame=off, offset=0pt]{#1\\#2:\\ \structureuservariable{subtitle}\\ (\structureuservariable{intro})} } ``` (see 6.pdf) I hope you can shed some light into setuphead with command. I search on the wiki, Stackoverflow and the manuals but didn't really find anything. Best, Gerion

As described, here is example: %%%%% \def\cmd#1{{\tt\textslash #1}} \def\cmdii#1{\tt #1} \def\cmdiii#1{\rm #1} \starttext \placecontent% if i dont place toc command , ConText can render it. \chapter{anything else} \section{\cmdi{with command} section} \section{\cmdii{with command} section} \section{\cmdiii{with command} section} \section{{\rm with command} section} % only this one work well \stoptext %%%% Am I missing something important? If so, please tell me what to do. Thank you so much. Muyik

Hi, When I run Example 1 given there, I get three bullet symbols, but no "column N ..." text. Note that the \starttext is *after* the \startitemize ... \stopitemize Q1: Is my ConTeXt installation broken, or is the wiki page showing output that does not correspond to the input? Q2: If the wiki page is inconsistent, is there an easy fix? Q3: If my installation is correct, why do I get bullet symbols *before* \starttext ? Thanks. Jim

Number in a circle
by Kip Warner 04 Jun '24

04 Jun '24

Hello list, I would like to typeset a number in a circle. Nothing fancy. No special colours, transforms, or complex metapost magic (which I am not familiar with). I have tried \circled{3} and \textcircled{3}, but ConTeXt does not appear to recognize these commands. Any help appreciated. -- Kip Warner OpenPGP signed/encrypted mail preferred https://www.thevertigo.com

Vanishing floats with location=split and \start ... \stopsplittext within
by Давыдов, Кирилл Александрович 04 Jun '24

04 Jun '24

Greetings, I have run into an issue whilst using \start ... \stopsplittext. I intended to use it for large code listings (using the t-vim module), however floats with location=split using that environment seem to vanish if there is nearly not enough text before the float to fill a page. Not only that, a second float like that seems to lead to fatal errors related to an unclosed group, however the document compiles regardless. The following MWE is an example of this. I am using ConTeXt version 2024.05.27 18:16. \definefloat[codelisting][codelistings] \setupcaption[codelisting][location=top] \setuplabeltext[english][codelisting=Listing ] %\showboxes \starttext \input knuth \input knuth \input knuth \input knuth % Filler. Filler. Filler. Filler. % uncomment to push out a full page. the float will appear \startplacecodelisting[ title=My great C program on display!, location=split, ] \startsplittext \tt \input zapf \stopsplittext \stopplacecodelisting \input ward \startplacecodelisting[ title=My second great C program on display!, location=split, ] \startsplittext \tt \input ward \stopsplittext \stoptext On a related note, one can also observe that with specific amounts of text a float may end up being split in two on a single page, however I could not replicate it. Additionally, code listings done with t-vim's commands seem to lose line numbering within \start ... \stopsplittext in splittable floats, but I figure that's more on the module authors. In any case, is there more I can do other than not use floats for code listings?

issue with signing
by Pablo Rodriguez 03 Jun '24

Dear list, I have the following sample \setupinteraction[state=start] \definefield[signature][signed] \defineoverlay[signature][my signature] \starttext \startTEXpage[offset=1ts,frame=on,framecolor=darkblue] sign: \inframed[background=signature,framecolor=darkred] {\fieldbody[signature][width=3cm,option=hidden]} \stopTEXpage \stoptext After compiling, I sign it with the following command (in latest from 2024.05.31 18:50): mtxrun --script pdf --sign --certificate=mycert.pfx --password=ABCabc a It requires the pass phrase (again?) and I get a signed PDF document. But Acrobat cannot find (or display) any signature in that PDF document. pdfsig (from poppler-utils-24.02.0) complains about digest mismatch: $ pdfsig a.pdf Digital Signature Info of: a.pdf Signature #1: - Signature Field Name: signature - Signer Certificate Common Name: John Doe - Signer full Distinguished Name: CN=John Doe,O=No Brainer - Signing Time: Jun 03 2024 16:24:03 - Signing Hash Algorithm: SHA-256 - Signature Type: adbe.pkcs7.detached - Signed Ranges: [0 - 6428], [10527 - 10912] - Not total document signed - Signature Validation: Digest Mismatch. mutool sign (from mupdf-1.24.1) also complains about modified document after signing: $ mutool sign -v a.pdf Verifying signature 3: Distinguished name: cn=John Doe, o=No Brainer, ou=, email=, c=XX Certificate error: Self-signed certificate. Digest error: Signature invalidated by change to document. Sorry, but what am I doing wrong here? Many thanks for your help, Pablo
