[NTG-context] TeX's \downbracefill and \upbracefill
Hello to all, in Knuth's "The TeXbook" page 225/226 (excerpt is appended here) braces are to be seen which I'd need to typeset a genealogical table. Now, the commands \downbracefill and \upbracefill are no context commands. Please, are there correspondings to them?

[NTG-context] Clickable url problem with \useurl and \url
Hello List, I notice an inconsistency in the clickable area when using \useurl. With the following example, both the \from and the \url are clickable in some lines (as noted iin the value of \from) but in others, the \from is clickable but not the \url. It does seem sensitive to the urlL, but I cannot see a pattern. Example: \setupinteraction [state=start] \useurl[earlBA] [https://www.bartleby.com/sv/welcome.html] [] [Not clickable] \useurl[earlPD] [https://www.perseus.tufts.edu/hopper/] [] [Not clickable] \useurl[earlWC] [https://www.worldcat.org/] [] [Not clickable] \useurl[earlFC] [https://www.futilitycloset.com/] [] [Not clickable] \useurl[earlQU] [http://www.quote-unquote.org.uk/] [] [Not clickable] \useurl[earlAL] [https://www.aldaily.com/] [] [Not clickable] \useurl[earlTL] [http://stephanus.tlg.uci.edu/] [] [Not clickable] \useurl[earlQI] [https://quoteinvestigator.com/] [] [Clickable] \useurl[earlLH] [https://languagehat.com/] [] [Clickable] \useurl[earlSF] [https://stancarey.wordpress.com/] [] [Clickable] \starttext \from[earlLH] (\url[earlLH]) \par \from[earlQI] (\url[earlQI]) \par \from[earlFC] (\url[earlFC]) \par \from[earlWC] (\url[earlWC]) \par \from[earlQU] (\url[earlQU]) \par \from[earlAL] (\url[earlAL]) \par \from[earlSF] (\url[earlSF]) \par \from[earlBA] (\url[earlBA]) \par \from[earlPD] (\url[earlPD]) \par \from[earlTL] (\url[earlTL]) \par \stoptext Should I use something other than \url[earlXX] here to get the clickable literal url from useurl? -- Rik Kabel ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://context.aanhet.net archive : https://bitbucket.org/phg/context-mirror/commits/ wiki : http://contextgarden.net ___
Re: [NTG-context] Unusual error with \doifinstring in \startbtxrenderingdefinitions ... \stopbtxrenderingdefinitions
An alternative solution is to isolate the setting of the
autopunctuation btx option:
```
% Because some common punctuation characters are escaped in publ-ini.mkiv,
% we have to set this option separately
\pushcatcodetable
\setcatcodetable\ctxcatcodes
\setupbtx[sbl][autopunctuation={!,.:;?}]% undelimited list of trailing
punctuation to move before footnote citations
\popcatcodetable

[NTG-context] body text and footnote space
Dear list, I note previous discussions on the matter of body text invading footnote space (as late as last year). As I am currently typesetting a 400 plus page academic text with hundreds of footnotes, and do not have the option of making them endnotes, I am facing this issue page after page. The only solution I have for now is to make per page layout adjustments to reduce a line or two, so there is a way to handle it, but given ConTeXt's 'perfection' generally, I would be very interested to know if there is any other solution forthcoming. I've tried various options in \setupfootnotes and \setuptolerance', but to no avail.

You can use pandoc to parse latex and convert it to mathml:
$ cat math.tex
\documentclass{amsart}
\begin{document}
\begin{align}
a &= \begin{pmatrix}
1 & 2 & 3 \\
1 & 2 & 3 \\
1 & 2 & 3
\end{pmatrix},
b &= \begin{pmatrix}
1 & 2 & 3 \\
1 & 2 & 3 \\
1 & 2 & 3
\end{pmatrix},
\\
c &= \begin{pmatrix}
1 & 2 & 3 \\
1 & 2 & 3 \\
1 & 2 & 3
\end{pmatrix},
d &= \begin{pmatrix}
1 & 2 & 3 \\
1 & 2 & 3 \\
1 & 2 & 3
\end{pmatrix},
\end{align}
\end{document}
$ pandoc -f latex -t html --mathml math.tex
http://www.w3.org/1998/Math/MathML;>a=(123123123),b=(123123123),c=(123123123),d=(123123123),\begin{aligned}
a = \begin{pmatrix}
1 2 3 \\
1 2 3 \\
1 2 3
\end{pmatrix},
b = \begin{pmatrix}
1 2 3 \\
1 2 3 \\
1 2 3
\end{pmatrix},
\\
c = \begin{pmatrix}
1 2 3 \\
1 2 3 \\
1 2 3
\end{pmatrix},
d = \begin{pmatrix}
1 2 3 \\
1 2 3 \\
1 2 3
\end{pmatrix},\end{aligned}
Processing this in context (see attached files), gives a partially working
solution. It doesn't look okay, but should be easily fixable.
Do note that this is almost same as compiling latex output to PDF because
editing presentation mathml by hand is no fun.

Many thanks for your reply, Hans.
This works in MkIV, but not in LMTX:
context.setupinteraction { title = main_doc.Info.Title }
BTW, is there a way to add CreationDate and ModDate?
Many thanks for your help again,

Re: [NTG-context] Short forms and abbreviations in bibliography
If it helps with troubleshooting, I've also tried to do this with
\fastsetup instead of \texdefinition:
```
\expanded{\abbreviation[\currentbtxtag]{\fastsetup{btx:sbl:cite:shorthand}}{
\fastsetup{btx:sbl:cite:listsubcite}}}
```
This also doesn't work, but I at least get a "Missing control sequence
inserted" error. The following MWE should reproduce the error (it modifies
the existing Chicago rendering, but since I couldn't figure out how to add
a shorthand field to the @book category in the chicago spec from within the
MWE, I just used the note field as a placeholder for it):
```

\startbuffer [bib]
@book{Author1:2016,

@book{Author2:2015,

% Setup a new cite alternative to test the desired functionality

this throws a Missing control sequence inserted error

this works, but recursively cites the same tag

[NTG-context] combination with lua
Hi,
I am trying to use a combination figure with luacode (both with latest MKIV
and LMTX).
However, the figures do not line up in the grid of the combination.
I get the correct result with examples 1 and 2 below, but example 3 using
lua functions for combination and externalfigure is what I wanted to use in
the first place.
MWE:
\starttext
\startluacode
-- Combination 1
context.startplacefigure({title = "Figure"})
context.startcombination({nx = "2", ny = "2"},
"\\externalfigure[cow][width=50mm]","Caption 1",
"\\externalfigure[cow][width=50mm]","Caption 2",
"\\externalfigure[cow][width=50mm]","Caption 3",
"\\externalfigure[cow][width=50mm]","Caption 4"
)
context.stopcombination()
context.stopplacefigure()
-- Combination 2
context.startplacefigure({title = "Figure"})
context.startcombination({nx = "2", ny = "2"},
"Picture 1","Caption 1",
"Picture 2","Caption 2",
"Picture 3","Caption 3",
"Picture 4","Caption 4"
)
context.stopcombination()
context.stopplacefigure()
-- Combination 3
context.startplacefigure({title = "Figure"})
context.startcombination({nx = "2", ny = "2"},
context.externalfigure({"cow"},{width = "50mm"}),"Caption 1",
context.externalfigure({"cow"},{width = "50mm"}),"Caption 2",
context.externalfigure({"cow"},{width = "50mm"}),"Caption 3",
context.externalfigure({"cow"},{width = "50mm"}),"Caption 4"
)
context.stopcombination()
context.stopplacefigure()
\stopluacode
\stoptext
Any hints on what I am doing wrong in example 3?
Thanks,
Adam

Similarly to previous examples, `mtxrun --script synctex --list
oeps.synctex`
only showed me that much:
```
mtx-synctex | begin page: 1
mtx-synctex | end page: 1
```
When I executed it on your SyncTeX file, it showed one line more:
```
mtx-synctex | begin page: 1
mtx-synctex | [ 71 135 136 149] : 6 : oeps.tex
mtx-synctex | end page: 1
```
Still, with both files Zathura gave me the same error :/. It is really
weird
though, that ConTeXt generated a different SyncTeX file for me for the same
exact file and command.
The versions of ConTeXt and SyncTeX:
```
$ synctex help
This is SyncTeX command line utility, version 1.5
usage: synctex [options] [args]
Synchronize TeXnology command-line client, version 1.21
$ context --version
mtx-context | ConTeXt Process Management 1.04
```
> btw, the script approach permits two way sync, so in texshop one can go
from pdf to source and source to pdf
Could you send me the exact commands for that? I can't get any meaningful
output from `mtxrun --script synctex` either. It always prints me just an
empty line. All the options described in usage look like they are for going
to
source code.

Re: [NTG-context] Regular online meet-up
Reminder: You’re invited to join tomorrow, Tuesday, October 12th, 15:00 CEST (11:00 EDT, 21:00 SGT) at https://lecture.senfcall.de/hen-rbr-rku-oke ConTeXt users of all levels are welcome! There’s no prepared subject/talk/presentation (from my side – feel free to share something). But I guess we will discuss PDF viewers some more... This is meant to be regular, i.e. every second Tuesday of a month. Next time is November 11th. Let’s see how this works out; maybe we need a different day/time. If we become many, it might make sense to offer something regional or language specific... [Howto] * No special software installation required; most modern browsers should work (WebRTC required). * Open the above URL, accept the privacy statement, * enter your name (or anything you want to be known as), * click "join" (or "start" if you’re the first), * click "with microphone", allow your browser to access it, check the audio. (Some strings might be different, I see the German interface, you should get the main language of your browser.) * Your microphone is muted if you join. Activate microphone and/or camera with the buttons at the bottom. * Minimize the default presentation with the "screen" button, bottom right. * If you’d like to share your screen or upload a file, you can make yourself the presenter: Click on your user name, change the setting, then you’ll see the "screen sharing" button beside the camera button; also there’s now "manage presentations" behind the "plus" button. Beware there is only one presenter, so don’t kill someone else’s presentation. [Technical hints] * Sound is usually better if you use a headset (less noise for everyone). * Connection problems are mostly due to low bandwidth or high latency on your side, e.g. with mobile connections. * If audio/video doesn’t work for you, you can still use the text chat. * Screen sharing needs a lot of bandwidth. * You can also join with a regular telephone (audio only, of course), call +49-6151-86275-22 (German landline); then you must enter a PIN that changes every time – if you need it, ask me for it via email. Mute/unmute your microphone with "0". [Netiquette] * Mute your microphone while you’re not talking. * It’s nice to show your face at least when you join. * If there are connection problems, stop camera sharing. * The room is set to “everyone’s a moderator“, I trust you...

Re: [NTG-context] undefined command in current latest
It looks like the argument of \getmarking is not expanded, since you get
"\it knuth" instead of an italicized "knuth" in the headers of this MWE:
\definemarking[myheader]
\setupheadertexts[{\getmarking[myheader][last]}]
\starttext
\dorecurse{10}{\samplefile{knuth}\marking[myheader]{\it knuth}\par}

Re: [NTG-context] Making metafun pictures fainter (shading, uncolored clash)
On 10/11/2021 6:30 AM, Gavin via ntg-context wrote: Hi List, I made good progress producing fainter pictures in metafun. Here is a uniformly accelerated cow in the style of my book. I abandoned transparency, since I actually don’t want to see through anything. I am using uncolored to get the fade.
