Re: [NTG-context] Documentation about CTX installation on MacOS X
Thank you very much for your quick answer to you both Fabrice and Henning ! It seems there is no detailed documentation about peculiar aspects of CTX on MacOS. For instance, the use of fonts database on unix-like and MacOS are a bit different (but not quite a lot) and this command : mtxrun --script fonts —reload Works fine with this one based on fontconfig : fc-cache -v -f There is some adaptation in the transition from Linux to MacOS, because one has to play and to look for the fonts paths which are a bit different with Mac than the Unix paths … > Le 2 janv. 2022 à 11:54, Henning Hraban Ramm via ntg-context > a écrit : > > Am 03.01.22 um 03:26 schrieb Jean-Pierre Delange via ntg-context: >> Now my question : I want to try CTX (ConTeXtver: 2021.12.30) on MacOS X >> (currently 10.13 High Sierra), while I was formerly working with old >> versions on Linux and Windows based systems.

Great! Thanks Hans, now it works. I replaced the "draw externalfigure"
commands by
draw externalfigure "./skysprite.png" xsized 4u ysized 5u shifted (0u,-0u);
draw externalfigure "./sandsprite.png" xsized 4u ysized 5u shifted (0u,-5u);

Re: [NTG-context] How to make \def accept block or buffer as part of (long) command argument
Uff, this is indeed deep tex. Thanks a lot for the example, Hans! I still need
to learn a lot.
After a walk and a bit of fresh air, I found another (much easier) way around
my problem. This works since I don't need to deal with #2 in any special way:
\tolerant\def\startMyCommand[#1]%
{
\startallbeautifulcontextcommands
% whatever #1 does
}
\tolerant\def\stopMyCommand%
{
\stopallbeautifulcontextcommands
}
Then one can do in the main files:
\startMyCommand
\beginMyBuffer
bla bla
\endMyBuffer
\stopMycommand

The lhdbend renders funny anyway. Maybe Taco is willing to have a look

Re: [NTG-context] Dynamic document variables from metadata

Happy New Year!
How would you implement a mechanism that takes arbitrary XHTML
tags and produces document variables? Consider:
After running XML setups, the following would write "Nature":
\documentvariable{journal}
The tricky part is doing this without pre-defining them. Here's a short,
self-contained example to help demonstrate:
|\startbuffer[xdoc] name="author"/>
\stopbuffer \startxmlsetups xml:xhtml
\xmlsetsetup{\xmldocument}{*}{-}
\xmlsetsetup{\xmldocument}{html|body}{xml:*}
\xmlsetsetup{\xmldocument}{head}{xml:meta} \stopxmlsetups
\xmlregistersetup{xml:xhtml} \startxmlsetups xml:html
% "author" is a special setup, not generalized
\xmlfilter{#1}{/head/meta[@name='author']/command(xml:author)} % What
goes here to make this dynamic?
%\xmlfilter{#1}{/head/meta[@name='journal']/command(xml:journal)}
\xmlflush{#1} \stopxmlsetups \startxmlsetups xml:author
\setupdocument[author={\xmlatt{#1}{content}}]
\setupdocument[metadata:author={\xmlatt{#1}{content}}]
\setupinteraction[author={\documentvariable{author}}] \stopxmlsetups %
How can this be generalized? %\startxmlsetups xml:journal
%\setupdocument[journal={\xmlatt{#1}{content}}] %\stopxmlsetups
\startxmlsetups xml:body \startdocument Author:
\documentvariable{author} \par Journal: \documentvariable{journal}
\stopdocument \stopxmlsetups \xmlprocessbuffer{main}{xdoc}{}|

\startxmlsetups xml:author

\setupdocument[metadata:author={\xmlatt{#1}{content}}]
\setupinteraction[author={\documentvariable{author}}]

[NTG-context] How to make \def accept block or buffer as part of (long) command argument
Hi list,
I'm playing around with blocks and buffers again, realizing that I cannot use
them inbetween a \start...\stop that I defined myself. Apparently, they work
between \startsection...\stopsection and the like, so I was wondering how I
should define or expand #2 in the MWE below to make TeX happily accept these
useful features?
Thanks a lot
Benjamin

\let\stopMyCommand\relax
\tolerant\protected\def\startMyCommand[#1]#2\stopMyCommand{
Optional argument #1
Content #2
}
\bf Here we test the command: Works \tf
\startMyCommand[is optional]
gets processed!
\stopMyCommand
\bf Here we test the block: Works \tf
\defineblock[MyBlock]

[NTG-context] Dangerous bends symbol in manfnt.afm accidentally chopped by LMTX?
Hi list,
using this example from the wiki, the dbend symbol appears cropped on the left
side on my machine (ConTeXt ver: 2021.12.10 11:41 LMTX fmt: 2021.12.14), but
not on the ConTeXt live server? Any possible reasons?
\definefontsynonym [bends] [file:manfnt.afm]
