Adding a line after the TOC
by jbf 08 Oct '24

08 Oct '24

I am struggling with something that might be simple enough, but... The author is insisting that on the TOC page, after all the chapters and their page numbers, I need to add the line (obviously without any page number associated with it): 'All translations are by the author'. I have trie various combinations of \writetolist and \writebetweenlist, and I can get his comment at the beginning of the TOC, but I cannot get it at the end, and perhaps with some vertical space separation from the main list. How can I place it at the end? Here is my simple MWE where at least I can get it at the beginning: \starttochead[title={Contents}] \setcounter [userpage] [7] \setupheader[state=stop] \placecombinedlist[content] \writebetweenlist[chapter]{All translations are by the author!} \stoptochead Julian

separatedlist with header repeating processing csv to table
by juh+ntg-context＠mailbox.org 08 Oct '24

08 Oct '24

Dear all, some years ago I asked about how to process a csv file in a table with repeating headers on following pages, but got no answer. https://www.mail-archive.com/ntg-context@ntg.nl/msg98903.html Now I am again working on this problem. I wonder if there is a better way to process csv files to a table with more flexibility? Or do I simply miss the switch to mark the first row in the csv file as the header that has to repeat? TIA juh

Deactivate (back)links of the bibliography
by Gerion Entrup 08 Oct '24

08 Oct '24

Hi, when typesetting bibliographies, ConTeXt seems to link back to the (first?) citation within the text. A side effect is that the whole reference entry is colored in the link color. Is there a possibility to deactivate the back linking or limit it to the key? This is also relevant, when the bibliography contains additional URLs or DOIs that link to external resources but are not highlighted since all surrounding text is colored in the same way. Here is a MWE: ``` \setupinteraction[state=start, color=red] \startbuffer[testdata] @Book{knuth1, author = {Donald E. Knuth}, title = {TEX and METAFONT. New directions in typesetting}, year = {1979}, publisher = {Addison-Wesley}, } @Article{someother, author = {Some Person and Some Otherperson}, title = {Another title}, year = {1900}, } \stopbuffer \usebtxdataset[main][testdata.buffer] \usebtxdefinitions[aps] \setupbtx[dataset=main] \definebtxrendering[bibrendering][aps][dataset=main] \starttext Knuth developed \TeX \cite[knuth1]. Several persons said something \cite[someother]. \placelistofpublications[bibrendering] \stoptext ``` (The whole bibliography entry is red here.) Gerion

Small issue with \breakhere in math mode
by Otared Kavian 07 Oct '24

07 Oct '24

Hi Hans and Mikael, I found a small issue in math mode with \breakhere. When \breakhere is followed by a brace in the following line, it creates a spurious break line. It can be fixed easily by the user by adding an empty line or issuing a \relax command, but I wanted to let you know. Please see the result of the following minimal example: % begin breakhere-bug.tex \starttext Compare \startformula \alignhere {\darkred c^2} = a^2 + b^2 \breakhere {\darkred z^2} = x^2 + y^2. \stopformula with \startformula \alignhere {\darkred c^2} = a^2 + b^2 \breakhere {\darkred z^2} = x^2 + y^2. \stopformula and with \startformula \alignhere {\darkred c^2} = a^2 + b^2 \breakhere\relax {\darkred z^2} = x^2 + y^2. \stopformula \stoptext % begin breakhere-bug.tex Best regards: Otared

How to improve appearance of bars in frac, sqrt, etc. on screens?
by Ralph 07 Oct '24

07 Oct '24

Hello, I’m relatively new to ConTeXt (version 2024.05.31, LMTX, standalone) and really enjoy learning it so far, but I have one little problem with the appearance of horizontal bars in math mode. It seems the way ConTeXt displayed horizontal extensible bars in math mode some time ago (as used in \frac, \sqrt, \overbar, ...) was similar to the way LaTeX (PDFLaTeX and LuaLaTeX) and Plain TeX handled this, but it has changed since then. Instead of one bar there are now multiple characters attached to each other. This makes it look more consistent with the font, but unfortunately it doesn’t display well in any PDF viewer I’ve tried (on Linux, so I’ve not tried Adobe Acrobat Reader). The bars look dotted, I guess it’s due to anti-aliasing (the dots disappear when anti-aliasing is disabled, but then of course everything looks pixelated). Two screenshots are attached (different zoom levels in PDF viewer) so that you know what I’m talking about. Source: \setuppapersize[S3] \starttext \startformula \sqrt{a^2 + b^2} = \frac{1000 \cdot c}{1000} \stopformula \stoptext Is there a way to switch to the old bars for documents viewed mainly on screens, or is there any other way to improve their appearance? I couldn’t find any documentation on this, so I would be very thankful if somebody here could help out. Best, Ralph

Draw leftframe to a description
by Gerion Entrup 07 Oct '24

07 Oct '24

Hi, I want to typeset an "excurses" description that is marked with a leftframe. The problem is that it spans about multiple pages and has footnotes. Here is an MWE: ``` %% -> mwe-framedtext.pdf \defineframedtext[excursusbg][ frame=off, leftframe=on, rulethickness=1mm, framecolor=blue, toffset=0mm, % there is an offset anyways ] %% -> mwe-textbackground.pdf % \definetextbackground[excursusbg] [ % location=text, % background=color, % backgroundcolor=lightblue, % frame=on, % loffset=10cm, % seems to have no impact % ] \definedescription[excursus][ text={Excursus:\ }, alternative=top, headstyle=bold, margin=1cm, width=broad, before={\startexcursusbg}, after={\stopexcursusbg}, ] \starttext \input ward \startexcursus[title={A Knuth extract}] \input knuth \stopexcursus \input ward \startexcursus[title={A much longer Knuth extract}] \input knuth Sometimes, sentences have footnotes\footnote{Some footnote}. \input knuth \input knuth \stopexcursus \stoptext ``` See the attached PDFs for the different results. In principal, I would like the excurses typesetted like to solution with \defineframedtext. However, this does not work with pagebreaks. Additionally, the leftframe is too long (it begins above the "Excursus" text). I tried toffset to let the leftframe begin exactly at the "Excurses" text without success. The solution with \textbackground looks somewhat promising. It supports pagebreaks, but draws above footnotes and prints a small rectangle at the end of the excursus. I also didn't found a way to specify a leftframe only. Also, loffset seems to have no effect, here. Do I use the false environments? Do you know a better solution? Gerion

Issues with vim and lettrine modules
by Tommaso Gordini 06 Oct '24

06 Oct '24

Hi all, I'm trying to compile Axel Kielhorn's guide available here: https://github.com/AKielhorn/Context-Intro However, I get compilation errors regarding *vim *and *lettrine*. Both modules are loaded in the source files, so I typed in the terminal: mtxrun --script install-modules --install vim lettrine but the errors do not disappear. I ask you if these two modules produce known errors. In any case, the sources are available at the URL indicated above. If needed, I'll paste a MWE here in a future message. Thanks in advance Tommaso

Vertical spacing in table of content
by Gerion Entrup 06 Oct '24

06 Oct '24

Hi, for my table of contents, I have set a style that makes sections and subsections smaller than chapters. However, in the rendering the vertical space seems not to adapt: It remains equal for all entities. Is there a possibility to reduce the vertical space between subsections and sections? I tried before and after but only get it to add additional space and not reducing it. Here is a MWE: ``` \setuplist[chapter][ style=bold, aligntitle=yes, ] \setuplist[section][ aligntitle=yes, style=\tfx, ] \setuplist[subsection][ aligntitle=yes, style=\tfxx, after={\blank[none]}, before={\blank[none]}, ] \starttext \placecontent \hairline \startchapter[title=foo] \startsection[title=foo] \startsubsection[title=foo] \stopsubsection \startsubsection[title=foo] \stopsubsection \startsubsection[title=foo] \stopsubsection \stopsection \startsection[title=foo] \startsubsection[title=foo] \stopsubsection \startsubsection[title=foo] \stopsubsection \stopsection \stopchapter \startchapter[title=foo] \stopchapter \stoptext ``` Gerion

different type in footnote
by Pablo Rodriguez 05 Oct '24

05 Oct '24

Dear list, I have the following sample: \setuppapersize[A9] \starttext \type{\a.bc}\footnote{\type{\a.bc}} \stoptext Using current latest from 2024.09.25 11:53, I get an extra space after \a in the footnote. This happens both with LMTX and LuaTeX. Could anyone confirm this? (A patch would be greatly appreciated, if this were a reproducible issue.) Many thanks for your help, Pablo
