x mark symbol and general symbol guide
by Gerion Entrup 16 Jun '24

16 Jun '24

Hi, I recently tried to typeset a table with checkmarks and x marks. \checkmark exists but is there a predefined x mark symbol (\xmark does not work)? In general: For LaTeX there exists the very helpful comprehensive LaTeX symbol list [1]. Is there a similar documentation for ConTeXt somewhere? Best, Gerion [1] https://www.ctan.org/pkg/comprehensive

Upgrading from 2021.03.05.20230120 -> 2023.05.05.20230730 breaks BibTeX footnotes
by Kip Warner 15 Jun '24

15 Jun '24

Hello list, I recently upgraded my distro release to Ubuntu Noble on one of my machines. The ConTeXt packages that were previously for 2021.03.05.20230120 were upgraded to 2023.05.05.20230730. Since the upgrade I've noticed my BibTeX footnotes that previously looked like this: https://imgur.com/vg7Xjd3.png Now look like this: https://imgur.com/I3hq6bM.png I haven't changed anything in the source of my document. This is how I typeset in my Environment.tex: % Select References.bib and name it the main database... \usebtxdataset[main][./References.bib] % Citation style... \usebtxdefinitions[apa] % Use our main dataset for citations... \setupbtx[dataset=main] \definebtxrendering[main][apa][dataset=main] % When listing all references use APS style... \definebtxrendering [list_all_references] [aps] [dataset=main, group=examples] \setupbtxrendering[main][ pagestate=start, continue=yes, numbering=yes] % Macro to put the citations as footnotes... \unexpanded\def\footnotecite{\dodoubleempty\domycite} \def\domycite[#1][#2]% {\ifsecondargument \footnote{\cite[alternative=entry,#1][main::#2]}% \else \footnote{\cite[alternative=entry][main::#1]}% \fi} Any help appreciated! -- Kip Warner OpenPGP signed/encrypted mail preferred https://www.thevertigo.com

How to improve appearance of bars in frac, sqrt, etc. on screens?
by Ralph 15 Jun '24

15 Jun '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

1: Modifying bibliography entries using lua, 2. Sort apa pubs according to year reverse author
by Ben Moon 14 Jun '24

14 Jun '24

Dear List, Here’s a beautiful example of lua checking a list of authors and conditionally formatting one: https://www.mail-archive.com/ntg-context@ntg.nl/msg88382.html I've dismally failed transferring the example to apa rendering style. Maybe someone can enlighten me. Furthermore, I’ve spent quite some time trying to reverse order the rendered list of publications by using apa such as, that the newest publication with author A… is on the top. Basically, sort in reverse according to year and then with author. As always, help is much appreciated. Thank you very much Ben

Prefix the text in an enumeration.
by Gerion Entrup 14 Jun '24

14 Jun '24

Hi, is there a way to automatically prefix the text body in an enumeration? Consider this example: ``` \defineenumeration[question][ alternative=top, text=Question, title=yes, titleleft=, titleright=, right={:}, headstyle=bold, ] \starttext Some text: \startquestion[title={How long does a loop last?}] \bold{Answer:} For a while. \stopquestion \stoptext ``` I'd like to have the `\bold{Answer:}` automatically. So for example something like this: ``` \defineenumeration[question][ alternative=top, text=Question, title=yes, titleleft=, titleright=, right={:}, headstyle=bold, prefix={\bold{Answer:}}, ] \starttext Some text: \startquestion[title={How long does a loop last?}] For a while. \stopquestion \stoptext ``` I tried to misuse `inbetween` for that but `alternative=top` seems to make a (not modifiable space) between the heading and the text body.

get measures as dimension in Lua
by Henning Hraban Ramm 13 Jun '24

13 Jun '24

Hi, when I define a measure on the TeX side, I used to get at the value in Lua with tex.getdim, like: \definemeasure[Bleed][3mm] tex.getdimen("Bleed") But now I get "incorrect dimen name". I need it as a dimension, since I do calculations with other dimensions like "topspace". How should I do this correctly? (I just assume this used to work – the code is old any maybe stuck in an intermediate state where I switched from \newdim to \definemeasure…) Hraban

comment on the wiki
by Pablo Rodriguez 13 Jun '24

Dear wiki maintainers (Taco at others), I have found in the user creation log: 05:40, 7 June 2024 User account FelicaEnyeart34 was created 22:59, 26 May 2024 User account NonaAlber414387 was created 04:33, 26 May 2024 User account Tony83264596 was created 15:17, 24 May 2024 User account WallyGarth was created I‘m afraid these four users may be only spamming accounts. I don’t know whether it is worth discussing this issue, but I have two questions: Is there any way in which regular wiki contributions may help in removing the accounts or at least all the pages generated with these accounts? Is there any way to fix the display of user contributions (such as mine, https://wiki.contextgarden.net/Special:Contributions/Ousia)? I have just discovered that the problem is to search for contributions in all namespaces (set by default), which triggers the error message: Namespaces with negative values are not supported. If main namespace is selected, everything works fine. I wonder whether it would be possible to set the main namespace as default to search for user contributions. Many thanks for your help, Pablo

Cite-proc Lua - Following up
by hdanielhixson＠gmail.com 12 Jun '24

12 Jun '24

Hello all, I hope you are well. This is my first time posting. So if I do so erroneously, I apologize. There is a LaTeX package called citation-style-language, backed by some software called citeproc-lua. The github page for the software is here: https://github.com/zepinglee/citeproc-lua It is an excellent piece of software. There was previous discussion about potentially integrating the software into Context. The following link should show a discussion that took place about the topic. https://www.mail-archive.com/search?l=ntg-context@ntg.nl&q=subject:%22Re%5C… I'm just wondering if there is more news about its potential integration with Context. Thank you, devs, for your hard work on making the software.

Scale content to height of the font, measure font height
by Gerion Entrup 11 Jun '24

11 Jun '24

Hi, I'd like to scale something (actually a symbol drawn in TikZ) to the exact high of the char 'M'. I found the scale environment for it but struggle to measure the correct font height. I found the "definemeasure/measure/measured" commands but they define a dimension and are not for doing measurements on rendered text. Is there a simple way to get the height a char as a dimension? MWE: ``` \starttext % Is it possible to replace 1cm with a common expression? This is the letter M. \scale[height=1cm]{a} should have the exact same size as M. This should also be true {\tfc with a bigger M. \scale[height=1cm]{a}}. \stoptext ``` Best Gerion
