help with \writetolist alignment
by jbf 05 Mar '25

05 Mar '25

I need a little help to get alignment of a \writebetweenlist correct. I currently have the following in the frontmatter (after the \placecombinedlist etc.) \startfrontmatter ... \starttitle[title={Introduction}] Blah blah blah \stoptitle \writebetweenlist[title]{Essays} \stopfrontmatter The Title header is almost flushleft with the margin, so I expected 'Essays' to do the same. Instead it lines up with all the Chapters in bodymatter which are indented somewhat (.5cm instead of .1cm for Title). In other words, I end up with: Introduction Essays How can I get 'Essays' to line up beneath Introduction? I thought because I am calling it a Title head it should follow what I have for title, viz., \setuplist[title][label=no,distance=.1cm,alternative=b,before=] Julian

Strange display of math when enabling export xml/html/xhtml
by Christoph Hintermüller 05 Mar '25

05 Mar '25

Dear Hans, Dear all Once angain me trying to convert my lecture notes into epub. At first: finally switching after some installation hassle to really latests context disttibution -------------------------------------------------------------------- mtx-context | Cmtx-context | ConTeXt Process Management 1.06mtx-context | mtx-context | main context file: /usr/local/share/context/tex/texmf- context/tex/context/base/mkiv/context.mkiv mtx-context | current version: 2025.02.28 18:16 mtx-context | main context file: /usr/local/share/context/tex/texmf- context/tex/context/base/mkxl/context.mkxl mtx-context | current version: 2025.02.28 18:16 onTeXt Process Management 1.06 mtx-context | mtx-context | main context file: /usr/local/share/context/tex/texmf-context/tex/context/base/mkiv/context.mkiv mtx-context | current version: 2025.02.28 18:16 mtx-context | main context file: /usr/local/share/context/tex/texmf-context/tex/context/base/mkxl/context.mkxl mtx-context | current version: 2025.02.28 18:16 -------------------------------------------------------------------- solved all my previous problems. But what i now notices is a strange behaviour regarding the math equations in the resulting html, xml and xhtml when there is at least one figure with an external graphic in the document (see attached hopefully minimal enough example). The xml/html/xhtml files contain a mathcontent tag/div which correctly contains the mathml for the equation. the tag/div it selve has the image attibute set which points to the first image file imported before. I do guess this is intended to be a fallback, in case browser or read can not properly handle and display mathml content. I do further guess that in my installation i do miss some external program or library or some environment variable is not set or not properly set. In parallel i have installed texlive - without outdated luatex context- as i do need latex for other stuff too. So my question is where and how to tweak installation to get a proper result. Best whishes Christoph

how to reset and switch fallbackfont?
by autumnus 03 Mar '25

03 Mar '25

hi, As described in the title, how to reset fallbackfont? I have created a number of Chinese typescripts and related fallbackfont (latin). However, in the actual operation process, I found that if you want to switch different fallbackfont, you must change the bodyfont at the same time (\setupbodyfont). The following is an example. How should I reset and switch to fallbackfont without changing the bodyfont? %%%%%%% \definefontfeature[zh][mode=node,script=hang,lang=zhs] \startsetups fallbacks:reset \resetfontfallback[serifwhatever] \resetfontfallback[serifboldwhatever] \resetfontfallback[serifitalicwhatever] \resetfontfallback[serifbolditalicwhatever] \stopsetups \startsetups fallback:lm \definefontfallback[serifwhatever] [lmroman10-regular] [0x0000-0x0400][force=yes] \definefontfallback[serifboldwhatever] [lmroman10-bold] [0x0000-0x0400][force=yes] \definefontfallback[serifitalicwhatever] [lmroman10-italic] [0x0000-0x0400][force=yes] \definefontfallback[serifbolditalicwhatever][lmroman10-bolditalic][0x0000-0x0400][force=yes] \stopsetups \startsetups fallback:eb \definefontfallback[serifwhatever] [ebgaramondregular] [0x0000-0x0400][force=yes] \definefontfallback[serifboldwhatever] [ebgaramondbold] [0x0000-0x0400][force=yes] \definefontfallback[serifitalicwhatever] [ebgaramonditalic] [0x0000-0x0400][force=yes] \definefontfallback[serifbolditalicwhatever][ebgaramondbolditalic][0x0000-0x0400][force=yes] \stopsetups \starttypescript [serif] [zhfont] \definefontsynonym [Serif] [AdobeSongStd-Light] [features=zh,fallbacks=serifwhatever] \definefontsynonym [SerifBold] [AdobeHeitiStd-Regular][features=zh,fallbacks=serifboldwhatever] \definefontsynonym [SerifItalic] [AdobeKaitiStd-Regular][features=zh,fallbacks=serifitalicwhatever] \definefontsynonym [SerifBoldItalic][AdobeHeitiStd-Regular][features=zh,fallbacks=serifbolditalicwhatever] \stoptypescript \starttypescript[myfont] \definetypeface[myfont][rm][serif][zhfont] \stoptypescript \usetypescript[myfont] \starttext \setups{fallback:lm} \setupbodyfont[myfont,rm,12pt] fonts {\bf fonts} {\bi fonts} {\it fonts} % will be lm font \\\the\font \setups{fallbacks:reset} \setups{fallback:eb} fonts {\bf fonts} {\bi fonts} {\it fonts} % expected eb but lm \\\the\font \setups{fallbacks:reset} \setups{fallback:eb} \setupbodyfont[myfont,rm,12pt]%% any other chinese font, and change to eb fonts {\bf fonts} {\bi fonts} {\it fonts} \\\the\font \stoptext %%%% best wishes, autumnus

New example, Distance between the background and the frame not wanted
by Ursula Hermann 03 Mar '25

03 Mar '25

Dear List, I have a little new example. What I do like to know: what command do I use, if I do not want a distance between the blackrule and the frame? I know, it is a problem with the distance, but I do not know the right command. \setuppapersize[A4] \blackrule[color=darkmagenta, height=3.ex, width=13.50cm]\par \defineframed [Me] [background=color,backgroundcolor=darkmagenta] \Me[frame=on, corner=rectangular, topframe=off, bottomframe=off, framecolor=blue]{Hello} \stoptext Many thanks Uschi

month form \currentdate in Roman numerals
by Pablo Rodriguez 03 Mar '25

03 Mar '25

Dear list, I would like to get the current month in Roman numerals (just now, it would be XII for December). The best I get is: \currentdate[\cldcontext{converters['R'] (tonumber(os.date("\letterpercent m", os.date(os.time()))))}] This strikes me as too complex (even for someone who cannot code). Is there now simpler way to write that? Just in case it may be relevant, this is part of the full day reference. Many thanks for your help, Pablo

Right-to-left natural tables
by Mohammad Hossein Bateni 02 Mar '25

02 Mar '25

Hello, Are natural tables still the recommended table mechanism in ConTeXt? How can I get the order of cells in each row reversed (going from right to left)? \starttext \placetable{Caption} {\bTABLE \bTR \bTD One \eTD \bTD two \eTD \eTR \bTR \bTD Three \eTD \bTD fourteen \eTD \eTR \eTABLE} \setupalign[r2l] \placetable{Caption} {\bTABLE \bTR \bTD One \eTD \bTD two \eTD \eTR \bTR \bTD Three \eTD \bTD fourteen \eTD \eTR \eTABLE} \stoptext I expect the second table to completely mirror the first one. Though the cell contents (as well as the caption) are reversed, the order of cells in the row are the same as in the first table. For columns, we have a *direction* key, but I couldn't find anything like that for natural tables. Thanks for your help, Mohammad

ConTeXt editing with Kate editor + Digestif lsp-server
by garulfo＠azules.eu 02 Mar '25

02 Mar '25

just discovering that it is possible to benefit from the lsp-server Digestif within Kate (a KDE text editor) to edit ConTeXt input files. - https://github.com/astoff/digestif - wiki page: https://wiki.contextgarden.net/Input_and_compilation/Text_editors/Kate Digestif provides hyperlinks to ConTeXt's commands wiki pages: great for new users.

\currentlistentrynumber and \currentlistlocation
by Pablo Rodriguez 02 Mar '25

02 Mar '25

Dear list, I’m struggling with an alternative list setup: \showframe \setupinteraction [state=start, style=, focus=standard] \enabledirectives[references.border=red] \definelistalternative [pmcols] [renderingsetup=pmcol] \startsetups [pmcol] \ifnum\modulonumber{3}{\currentlistentrylocation} = 1 \dontleavehmode% \rlap{\[\currentlistentrynumber\]\nbsp\nbsp\nbsp% \currentlistentrypagenumber\narrownobreakspace·% \narrownobreakspace\the\numexpr1+\currentlistentrypagenumber\relax} \orelse\ifnum\modulonumber{3}{\currentlistentrylocation} = 2 \hfill\[\currentlistentrynumber\]\nbsp\nbsp\nbsp% \currentlistentrypagenumber\narrownobreakspace·% \narrownobreakspace\the\numexpr1+\currentlistentrypagenumber\relax \else \hfill\llap{\[\currentlistentrynumber\]\nbsp\nbsp\nbsp% \currentlistentrypagenumber\narrownobreakspace·\narrownobreakspace% \the\numexpr1+\currentlistentrypagenumber\relax}\crlf \fi \stopsetups \definestructureconversionset[rom][n,R] \setuphead[title] [page=yes] \setuphead[chapter] [page=even, sectionconversionset=rom] \starttext \placelist [chapter] [alternative=pmcols, criterium=all, interaction=all] \dorecurse{100} {\startchapter \samplefile{zapf} \stopchapter} \stoptext The sample above works only here, not in my real world document. The main reason is that \currentlistentrylocation doesn’t give the same number as \currentlistentrynumber. Is there any way (considering the sample above, where chapter has to be in Roman capital numbers) to get the pure number value of \currentlistentrynumber? BTW, I wonder also how could I get a link to the corresponding chapter (as standard lists always have with interaction enabled). Many thanks for your help, Pablo
