workaround for wrapping SHA512
by Pablo Rodriguez 05 Oct '23

05 Oct '23

Dear list, I have just added another workaround to long hashes (such as SHA512). It interleaves colons every two chars: https://wiki.contextgarden.net/Wrapping#Another_workaround_interleaving_col…. This makes a longer output, but it is more readable too. Just in case it helps anyone (who previously discussed this in this mailing list), Pablo

Re: [NTG-context] checkbox in fields show the word yes

Firefox doesn't show the "yes", nor Acrobat X, but SumatraPDF does. I modified your definition as: \definefield[test][check][cbox][][] And now the "yes" doesn't appear. However, I don't know how this affects the functionality of the form. -- Andrés Conrado Montoya Andi Kú andresconrado(a)gmail.com http://sesentaycuatro.com http://messier87.com http://chiquitico.org ---------------------------------------- Los fines no justifican los medios, porque la medida verdadera de nuestro carácter está dada por los medios que estamos dispuestos a utilizar, no por los fines que proclamamos. ---------------------------------------- “You develop an instant global consciousness, a people orientation, an intense dissatisfaction with the state of the world, and a compulsion to do something about it.

Problems with line numbered program listings
by Bruce Horrocks 04 Oct '23

04 Oct '23

I'm trying to typeset some program listings with annotations alongside. I've tried both columns and tabulate but both have (different) issues: 1) Plain \typefile won't allow the line numbers to be in the text - they stay in the margin whch I don't want. 2) \typefile using a \definedtyping name does work and works in \columns as well. This is great until my listing is too long to fit on a page and then I'd rather have the column continue onto the next page but \columns balances of course. 3) \tabulate allows a single cell to continue down over the page exactly as I'd like, but the line numbers disappear altogether. (And it has to be a single cell because the program listings are in source files that I want to include using \typefile rather than re-enter to avoid typos.) You can see each of these effects with the following MWE which first needs a file called "three_lines.txt" to be created in the local directory containing the lines: one two three %%%% begin \setuplinenumbering[location=text,style=\small\tt] \starttext Location=text not working in main body \typefile[numbering=line]{three_lines.txt} But it does work if a custom typing environment is created. \definetyping[MyTyping][style=\tt] \typefile[MyTyping][numbering=line]{three_lines.txt} Still works if used in a column \startcolumns \typefile[MyTyping][numbering=line]{three_lines.txt} \column :-) \stopcolumns \blank But doesn't work if used in tabulate \starttabulate[|p|p|] \NC \typefile[MyTyping][numbering=line]{three_lines.txt} \NC No line numbers at all :-( \NR \stoptabulate \stoptext %%%% end What I'd most like is for tabulate to allow \typefile with line numbers if at all possible. — Bruce Horrocks Hampshire, UK

bibliography questions
by Henning Hraban Ramm 04 Oct '23

04 Oct '23

My example is setup as advised in the manual: """ %\mainlanguage[de] \usebtxdataset[beispiel][bib_example.bib] \setupbtx[dataset=beispiel] %\usebtxdefinitions[apa] \definebtxrendering[beispiel][apa][dataset=beispiel,group=beispiele] \starttext \placelistofpublications[beispiel] \cite[authoryear] [WiFo2010] \cite[authoryear] [rattenhka] \stoptext """ But I get the error message: """ system > error: invalid parent apa for beispiel, apa defined too (best check it) system > error: invalid parent btx:apa for btx:beispiel, btx:apa defined too (best check it) """ Are these messages wrong? And why do they come from "system" and not from "publications"? My minimal example works anyway, still investigating why it doesn’t in my book. Another question: Consider: @Book {rattenhka, author = "Bettina von Arnim and Gisela von Arnim", title = "Das Leben der Hochgräfin Gritta von Rattenzuhausbeiuns", … } The authors are usually given as “Bettina and Gisela von Arnim” (mother and daughter; similar “Jacob and Wilhelm Grimm” as brothers or “Bettina and Achim von Arnim” as a couple) – is there a good solution for related authors?

Using Farad with \unit messes up feet, µ not recognised as prefix
by Marco Patzer 03 Oct '23

03 Oct '23

Hi! I struggle using the unit Farad (unit of capacitance): \starttext %% prints 10 10 ft \unit{10 F} \unit{20 ft} \registerunit [F=Farad] \setupunittext [Farad=F] %% prints 10 F 20 F⋅t \unit{10 F} \unit{20 ft} \stoptext When registering Farad as new unit it messes up feet. This looks like a bug to me, since “20 ft” does not contain a capital “F” and units are case-sensitive. How to use Farad correctly without messing up other units? 2nd issue: The prefix “µ” is not recognised: \starttext %% prints 10 nm 20 30 µm \unit{10 nm} \unit{20 µm} \unit{30 um} \stoptext I would expect “20 µm” to produce the correct result. Can we make “µm” also produce the same result as “um”? Marco LMTX 2023.09.04 19:15

Chemistry in LMTX
by Henning Hraban Ramm 03 Oct '23

03 Oct '23

I tried to update https://wiki.contextgarden.net/Chemistry, since nearly all of the links were dead, and I couldn’t find any documentation about \chemical / \startchemical. In the wiki page you can see that there’s still some working code for chemistry, but it looks very broken. ppchtex.mkiv is apparently still code from 1996 (and can’t work, since neither PicTeX nor PStricks are supported in LMTX any more). chem-str.lua seems to be an updated version by Alan & Hans Did I miss something?

Offline documentations
by Juliano David Hilario 02 Oct '23

02 Oct '23

Is there a way to view the documentations offline? Sort of the way the Python docs work, where you could just search for a subject and it will function regardless of internet connection. If it's not yet working, I could contribute some of my time if it's not that a heavy of a task. Something like this would be convient, since some like to search by topic. Though since we probably have the common ground of liking writing, we, or most of us, prefer referring to current manuals out there.

Re: wiki update: Modules
by Andres Conrado Montoya 02 Oct '23

02 Oct '23

In the wiki, if I click a link to check a source code file (for example https://source.contextgarden.net/tex/context/base/mkiv/m-catchword.mkiv) I get a blank page with a very long list of source files on the left. If I search for the file with my browser's ctrl+f on that page, it returns zero results. I'm using Chrome. It happens for every link to source files. Not sure if it's a problem with my setup, but I have noticed that before, in different machines. Can anybody else confirm if they can correctly see the source files when clicking the links? -- Andrés Conrado Montoya Andi Kú andresconrado(a)gmail.com http://sesentaycuatro.com http://messier87.com http://chiquitico.org ---------------------------------------- Los fines no justifican los medios, porque la medida verdadera de nuestro carácter está dada por los medios que estamos dispuestos a utilizar, no por los fines que proclamamos. ---------------------------------------- “You develop an instant global consciousness, a people orientation, an intense dissatisfaction with the state of the world, and a compulsion to do something about it.

Finding the position of an image on the page.
by peter.hopcroft＠icloud.com 02 Oct '23

02 Oct '23

Hello list, Can I find the position of an image on the page after I have placed the image with \externalfigure? For example, the top, left corner of the image might be 50 mm in from left side of page and 120 mm down from the top of the page. I know I can use \getfiguredimensions to find information about the placed image, but it does not give me the position of the image. Thank you Peter Hopcroft

formula alignment for mathalign
by Aditya Mahajan 28 Sep '23

28 Sep '23

Hi, The `align` parameter of `\setupformulas` is ignored in mathalign. Consider the following MWE: \setupformulas[align=flushleft,leftmargin=2em] \starttext \startformula A = B \stopformula vs \startformula \startalign \NC A \NC B \NR \NC A \NC B \NR \stopalign \stopformula \stoptext The first display formula is flush left, but the aligned formula is centered on the page. This appears to be a regression compared to MkIV, where the above example works correctly. Aditya

Re: Install fonts on MS Windows

I did a test with Windows 10. Installed a fresh copy from the garden, Got the GFS Didot font from Google Fonts, and installed it system-wide (C:\Windows\fonts). After that, I ran mtxrun --script fonts --reload Then tried the pattern suggested but did not work. However, then I tried a pattern without asterisks: mtxrun --script fonts --list --pattern=didot --all This returned the font: C:\griego>mtxrun --script fonts --list --pattern=didot --all identifier familyname fontname filename subfont instances gfsdidot gfsdidot gfsdidotregular c:/windows/fonts/GFSDidot-Regular.ttf gfsdidotnormal gfsdidot gfsdidotregular c:/windows/fonts/GFSDidot-Regular.ttf gfsdidotregular gfsdidot gfsdidotregular c:/windows/fonts/GFSDidot-Regular.ttf theanodidot theanodidot theanodidotregular c:/windows/fonts/TheanoDidot-Regular.ttf theanodidotnormal theanodidot theanodidotregular c:/windows/fonts/TheanoDidot-Regular.ttf theanodidotregular theanodidot theanodidotregular c:/windows/fonts/TheanoDidot-Regular.ttf trying to render Pablo's example didn't work at first, but after i called the fonts with the name returned by mtxrun: \mainlanguage[agr] \definefontfamily[mainface][rm][gfsdidot] \definefontfamily[mainface][ss][theanodidot] \setupbodyfont[mainface] \starttext GFS Didot: \doloopoverlist{\tf, \it, \bf, \bi} {\recursestring\input aristotle-grc\par} \ss Theano Didot: \input aristotle-grc \stoptext Everything compiles correctly, and the font is used.

Toggling the symbol for the zero-width joiner and related Unicode control characters
by Hamid,Idris 23 Sep '23

23 Sep '23

Dear gang, Within a font, relevant Unicode control characters such as the zero-width joiner usually have symbolic representation, but in printing the symbols are usually suppressed, while the effect of each character is maintained. In some text editors, such as Windows Notepad (Uniscribe), there is the option "Show Unicode control characters" which toggles the symbols and keeps the effects. I seem to recall that ConTeXt has/had a similar mechanism for toggling the symbols for Unicode control characters but cannot find it. Does anyone know or recall where the symbol-toggling mechanism is? If not, what would be the simplest way to implement it? Here is a MWE (note that the three control chars might be invisible in your email client): ============== \startTEXpage[offset=1em] \definedfont[almfixed at 14pt] ZWJ: ‌ ZWNJ: ‍ NBSP: \stopTEXpage ============== In Notepad, all three control characters can be turned on or off at once. In Scintilla, only the NBSP appears and there is no option to toggle. In ConTeXt, ZWJ and ZWJ appear as symbols, but NBSP does not. Thank you in advance for your guidance. Best wishes Idris -- Idris Samawi Hamid, Professor Department of Philosophy Colorado State University Fort Collins, CO 80523
