Math manual
by Mikael Sundqvist 17 Jun '24

17 Jun '24

Hi! Hans just uploaded a new version. I am not writing about the news in that version (although there are some fun things!), but rather to announce that the math manual is finally included. We have been working on and off since 2021 on math and therefore also on this document, and we finally believe that both math and the document are now in a state that should be sufficiently useful and not too confusing. You can find a screen and a paper version: ./tex/texmf-context/doc/context/documents/general/manuals/mathincontext-screen.pdf ./tex/texmf-context/doc/context/documents/general/manuals/mathincontext-paper.pdf The versions are generated from the same tex files, so the content (except for some chapter pages only available in the screen version) should be the same. We hope that this will be useful for all of you who use math in your documents. If you have any questions, find any errors, or miss something, please let us know. We consider the document not to be finished, so there will be updates. Also, we will also at some point include the tex files, but that will have to wait a bit. /Hans and Mikael

I remember there was an incantation to work with expanded doif's etc. In this case I need \doifelsedefined{ARG} with ARG expanded. I lost the exact spelling of the command and dldn't find it in the garden. What was it? yours sincerely dr. Hans van der Meer

Faulty PDF output files after updating to version 2024.06.14
by Ralph 16 Jun '24

16 Jun '24

Hi, while trying out the new version of ConTeXt LMTX (2024.06.14 09:18) I encountered some problems related to the PDF output files. First, I tried to print a single page of the excellent new math manual (many thanks to everyone involved in creating it, it’s great for beginners like me and surely for experienced users too), but I noticed that all of the extensibles in the formulas (like the bar in \frac, \sqrt, long integral signs, and probably more) have disappeared. Everything else was printed correctly. After investigating, I found out that Okular on Linux converts the PDF file to PostScript before printing (at least on my system), and I was able to replicate this behavior by converting it manually to PostScript with Poppler (pdftops in.pdf out.ps) or Ghostscript (pdf2ps in.pdf out.ps). Printing from Firefox was not affected for me as it did not convert to PostScript. I was unable to reproduce this with my own documents (created with ConTeXt LMTX 2024.05.31 18:50), so I decided to try this with the new version. And with it, that was indeed reproducible. To ensure that this is the PDF’s fault, I decided to try this on Windows with Adobe Acrobat Reader on a different Computer with another fresh installation of ConTeXt. But it wasn’t any better: Adobe Acrobat Reader displayed two different error messages when trying to scroll through or zoom in on the math manual: 1. “An error exists on this page. Acrobat may not display the page correctly. Please contact the person who created the PDF document to correct the problem.” 2. “There was an error processing a page. A number is out of range.” Sometimes the first one is shown, sometimes the second one. Additionally, some parts of the manual were blank (they were displayed correctly in Okular, Firefox, and many more viewers), I suspect those who contain extensibles in formulas. Following example leads to the same behaviour: \setuppapersize[S33] % Just to make page smaller \setupbodyfont[modern, 11pt] \starttext Hello. \startformula \frac{a^2 + b^2}{1} = c^2 \stopformula \page Hello. \startformula a^2 + b^2 = c^2 \stopformula \stoptext The first page is empty in Acrobat Reader, whereas it’s displayed correctly in all other PDF viewers I tried. But again, when converting to PostScript, the fraction bar vanishes. The second page is fine. I attached the faulty example.pdf file and some screenshots of it opened in different PDF viewers, and of the math manual. The screenshot of the math manual opened in Acrobat Reader shows that the second half of the page is completely gone. example_pdftops-ps2pdf.pdf is example.pdf converted to PostScript with Poppler and then converted to PDF again with Ghostscript (attaching the PostScript file isn’t possible because of file size). Opened in Okular or other Poppler based viewers you’ll see a dot instead of the fraction bar (which gets infinitely smaller while zooming-in), and openend in Firefox, MuPDF or Acrobat Reader you’ll see a cut off bar. One last thing, for some reason “\italiansqrt” on page 52 of the math manual is converted perfectly fine to PostScript (at least it looks right). Please let me know if you would like me to provide more information. Best, Ralph

Pocket Diary Photo Calendar: how to specify on which day the week begins?
by Michael Guravage 16 Jun '24

16 Jun '24

Hi, I am trying to use the Pocket Diary <https://ctan.org/pkg/context-pocketdiary> module to create a photo calendar as described in the Calendar Examples <https://ctan.org/pkg/context-calendar-examples>. The examples work fine. By default weeks begin on Monday. Does anyone know how to specify that weeks begin on Sunday? I have searched through all the setvariable assignments, but nothing seems applicable. I have attached an example file so you needn't retrieve all the examples. Any help would be appreciated. -- With kind regards, Michael <http://literatesolutions.com>

Could anyone confirm the issue? Many thanks for your help in advance, Pablo

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

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
