I will try to explain what I understand from this (intended for Uschi). Given that there are two modules (m-zint and zint), there are two options: 1. Either you use the LMTX module (\usemodule[zint]) and you need the Zint library (as explained in https://wiki.contextgarden.net/Barcodes#Zint_module). 2. Or you use the MkIV module (\usemodule[m-zint]) and you need the Zint binary installed and CMD should be able to invoke it (already knowing its past). You may have the Zint binary installed, ConTeXt may be generating the required EPS files, but either Inkscape is not installed (or its path is unknown to the system), or ConTeXt cannot simply find where the converted PDF versions of the zint images are. If I have the following source in testing-barcodes.tex: \usemodule[m-zint] \starttext \startTEXpage[offset=1dk] \barcode[alternative=isbnx, text=9783865419026, width=4cm] \stopTEXpage \stoptext ConTeXt compiles it generating to extra files (when compared to the pure zint module for LMTX only): zint-isbnx-fe90eda0e93cf020312eps m_k_i_v_zint-isbnx-fe90eda0e93cf020312_eps_c60ccda70ef.pdf (Removed some characters in strings so file names fit in a single line.) The first file is generated by the Zint binary itself. The second one is the automatic conversion (through Inkscape) that ConTeXt needs to embed EPS (and SVG) files in the final PDF document. If m_k_i_v_zint-*.pdf files are missing, the problem might be that Inkscape isn’t installed (or its path is unknown to the system). If also zint-*.eps files are missing, you should find where Zint is generating them.

A "better" solution is to put
doi = {https://doi.org/__doi__},
in your bibtex database
but I would actually use
url = {https://doi.org/__doi__},
Not all editors want the complete url for the doi, but some do.
The current scheme lets the user define url= and doi= as they wish (and
even both) and does not impose a particular format.

I also use fractions frequently, so I’ve tried a few things.
Some fonts have superior and inferior numbers that can be used to make small
slash fractions. I’ve done this, but my method is not pretty. Hraban suggested
using font features for this, but I haven’t learned how to do that. Any advice
is welcome.
Example code below uses the Libertinus font, which has these superior and
inferior numbers, to produce sample paragraph demonstrating a few options for
fractions in text.
Gavin
\usetypescriptfile[libertinus]
\setupbodyfont [libertinus,11pt]%
\setupinterlinespace[line=3.1ex]
\define\fracone{\getnamedglyphdirect{libertinus}{onesuperior}} % 1
\define\fracthree{\getnamedglyphdirect{libertinus}{threesuperior}} % 3
\define\fracnine{\getnamedglyphdirect{libertinus}{ninesuperior}} % 9
\define\thirteenths{\textfraction\getnamedglyphdirect{libertinus}{oneinferior}\getnamedglyphdirect{libertinus}{threeinferior}}
% /13
\define\onethirteenth{\text{\fracone\thirteenths}} % 1/13
\define\threethirteenths{\text{\fracthree\thirteenths}} % 3/13
\define\ninethirteenths{\text{\fracnine\thirteenths}} % 9/13
\starttext
Some small fractions are already available in many fonts, like \onehalf\ and
\onethird. Others can be built using superior and inferior numbers in some
fonts. This includes the fractions required to
find the normal and shearing stresses on an oblique plane defined by
$l=\sqrt{\threethirteenths}$, $m=\sqrt{\onethirteenth}$, and
$n=\sqrt{\ninethirteenths}$.
Of course, you could just find the normal and shearing stresses on an oblique
plane defined by $l=\sqrt{3/13}$, $m=\sqrt{1/13}$, and $n=\sqrt{9/13}$.
Vulgar fractions are between these extremes.
Find the normal and shearing stresses on an oblique plane defined by
$l=\sqrt{\vfrac{3}{13}}$, $m=\sqrt{\vfrac{1}{13}}$, and
$n=\sqrt{\vfrac{9}{13}}$.
I included more text than strictly necessary in this example to demonstrate the
effect on line spacing.

[NTG-context] Re: margin bigger than backspace pushes it outside the edge
Thanks Wolfgang. Is this expected behavior? I'm very much confused with my second example: \setuppapersize[A5][A4] %\setuplayout[location=middle] \setuplayout[location=middle,width=middle] %\setuplayout[location=middle,width=middle,backspace=2.5cm] \usemodule[ipsum] \starttext \showframe Hello \stoptext With just \setuplayout[location=middle] the left margin gets outside the left edge, there's also a gap to the right of the right margin and, to the eye, it seems that the sum leftmargin+leftmargindistance+textwidth+rightmargindistance+rightmargin doesn not match the page width. With \setuplayout[location=middle,width=middle] all is symmetrical but the two margins go outside the edges. With e.g. \setuplayout[location=middle,width=middle,backspace=2.5cm] I can fit everything by manually adjusting the backspace to I'm not sure what the right value. I couldn't adjust the page layout on some more complex document, so I'm going back to the most basic layout and trying to make it work on the simplest document possible.

Or, for inline math, $\sqrt{1/3}$.
radicals are somewhat special to deal with:
- multidimensional delimiter
- vertical spacing inside
- horizontal spacing oustside
- anchoring degrees
- left and right radicals
- more consistent rules (char based)
- size dependent additional spacing (avoid clash)
- normalize size across formula
- lack of granularity in variants sizes
by now we have dealt with all of that (some not in the current release),
think of additional control in the engine, compensation for insufficient
opentype math features, companion fonts with more sizes
there will always be suboptimal cases but the average is ok (we put
radical - character kerning on hold because it is a lot of definitions)
and we don't want to add hard to fight heuristics
so to inline: in most cases the solution that Adirya suggests will work
out okay with respect toline spacing

Many thanks for your reply, Bruce.
The following code seems to solve my issues:
\def\MyGoTo#1[#2]{\setupinteraction[state=start, style=,
display=new, color=, contrastcolor=,
page={auto,name},
focus=standard]%
\goto{#1}[#2]}
\setupinteraction[state=start, style=,
display=new, color=, contrastcolor=,
page={no},
focus=standard]
I didn’t thought this issue would be so easy to be solved.

and:

etc. works here.

Many thanks for your fast reply, Bruce.
I wanted to reply much sooner, but it was really impossible for me.
>From your explanation, the first link (body to footnote, your point b)
has destination to fit the whole page inside the viewer.
The second link (footnote to body, your point c) has the destination to
reach a position inside the page (where the destination lies). This is
what "focus=standard" should achieve.
In PDF terms (simplified), fit to page destinations are /Fit
destinations and placed destinations are /XYZ destinations.
This sample shows what might be the root issue here:
\setupinteraction[state=start, page=name, focus=standard]
\starttext
\completecontent
\chapter{Chapter}
a\footnote{b}
\stoptext
ConTeXt handles internally links in categories. For some reason unknown
to me, "page=name" triggers that special operation links contain /Fit
instead /XYZ destinations.
This is similar to the wrong link destinations (fit instead of standard)
from TOC (but not in footnotes [which are right]) when compiled with MkIV:
\setupinteraction[state=start, focus=standard]
\starttext
\completecontent
\chapter{Chapter}
a\footnote{b}
\stoptext
I hope it is clearer now. Let me know if it is not.
My issue is that I cannot avoid having "page=name" for links to external
documents, but this breaks footnotes and other special operation links.
Many thanks for your help,
Pablo

[NTG-context] Re: multipage metapost output from ConTeXt
Hi Mikael,
here's a very simple mwe for the label(textext()) issue. On page 1, the text
"Word 1" should be drawn in position z1. On page 2, the same text in the same
position should be visible, and the text "Mot 2" in position p2 should be
added. And so on.
\startMPinclusions
picture p[];
path TheFrame ;
TheFrame := fullsquare scaled 5in ;
z1 = (60,40);
z2 = (40,90);
z3 = (10,70);
p1:=image(
label(textext("Word 1"), z1);
);
p2:=image(
label(textext("Mot 2"), z2);
);
p3:=image(
label(textext("Parola 3"), z3);
);
\stopMPinclusions
\starttext
\dorecurse{3}{ % Frame
\startMPpage[pagestate=start]
currentime := #1 ;
% Just for learning :
draw TheFrame withpen pencircle scaled .1in withcolor magenta ;
draw textext("T="(currentime)) scaled 2 shifted(0,2in) withcolor
magenta ;
for k=1 upto currentime: draw p[k]; endfor
setbounds currentpicture to TheFrame ;
desiredformat := 1080;% In pixels (will be converted by default at 72dpi)
currentpicture := currentpicture xysized (desiredformat ,desiredformat );

[NTG-context] Re: multipage metapost output from ConTeXt
Dear Aditya and Fabrice,
thanks for your responses.
I included some of Fabrice's code into mine for testing purpose, and indeed the
multipage works now.
What is bizarre is that issues appear now that didn't appear before:
Path A is drawn with color red on page 1, and in color black on all following
pages, while it should stay red.
textext(, ) is overwriting with "T="(currentime)
which has been used previously in textext() before the for k=1 endfor loop.
This overwriting happens only for the first textext() which occurs inside the
for k=1 endfor loop. All other textext() inside the for k=1 endfor loop are not
drawn at all. If the line « draw textext("T="(currentime)) scaled 2
shifted(0,2in) withcolor magenta ; » is commented out, the first textext()
inside the for k=1 endfor loop is not drawn neither. It must be an issue with
textext(), because when I replace textext() by lmt_outline[], the text is drawn.

[NTG-context] multipage metapost output from ConTeXt
How can I achieve multipage metapost output from ConTeXt? The result should be
a multipage pdf. It contains just a metapost graphic per page. The graphic has
always the same bounding box and evolves from page to page: Some elements to be
drawn are added, and some others would ideally also be removed, while keeping
elements which has already been drawn on previous pages. I can manage when it
is not possible to remove elements (in that case I'll just cover them with a
covering element).
I saw that it is possible to achieve my goal with standalone metapost, as
described here:
https://tex.stackexchange.com/questions/471662/mptopdf-is-multipage-output-pdf-possible
But I'll need to achieve this with Metapost inside ConTeXt because I use labels
in Metapost which print text in Japanese, Korean , Arabic and Roman script:
Thanks to ConTeXt, I can define appropriate fonts for each script. All this
works already in my working example.
The only unsolved problem is to ship out multiple pages.
For the minimal working example, I didn't remove the font defining part,
because having 4 different fonts is a condition of my use case. The graphic on
the other hand is some simple dummy nonsense graphic not from my project. The
graphic is in the provided example drawn as a summing up of layered drawing
steps (6 steps, to be precise), so no removing is implemented here (because I
don't know how that would be done). If each of the figures 1 to 6 of my mwe can
be put alone on a page, I'd be already very happy. Now, they're put on top of
each other all on the same single page, also on top of figure 0.
The desired multipage pdf will be used in presentation mode of a pdf viewer and
skipped forward and backward from page to page (that is from drawing step to
drawing step).

[NTG-context] Re: mathalignment; alignment of columns
By the way, if it's been a few years since the changeover, isn't it surprising that the examples on the contextgarden website still use the old syntax? Are you aware of an official announcement of the new syntax? After all, this seems to mean that old texts are no longer rendered correctly, at least not after a new PDF generation. This is no small matter. ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / https://mailman.ntg.nl/mailman3/lists/ntg-context.ntg.nl webpage : https://www.pragma-ade.nl / https://context.aanhet.net (mirror) archive : https://github.com/contextgarden/context wiki : https://wiki.contextgarden.net ___
[NTG-context] Re: mathalignment; alignment of columns
No, it seems to have been my mistake. I must apologize. I have tested the syntax with the preceding column numbers again, and lo and behold: it works. Unfortunately, I can no longer understand what went wrong with my first test of the new syntax. In any case, thank you very much for your support. You have helped me a lot. ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / https://mailman.ntg.nl/mailman3/lists/ntg-context.ntg.nl webpage : https://www.pragma-ade.nl / https://context.aanhet.net (mirror) archive : https://github.com/contextgarden/context wiki : https://wiki.contextgarden.net ___
[NTG-context] Re: mathalignment; alignment of columns

[NTG-context] mathalignment; alignment of columns
Something as elementary as "mathenvironment" can't really be faulty, can it?
According to my recent tests, a mathalignment environment does not seem to
react (any more) to the values of the "align" option.
The source code hab been rendered correctly a few years ago,
Minimal example 1:
\starttext
\startformula
\startmathalignment[n=2,align={left, right}]
\NC always aligned to the right \NC = u + at, \NR
\NC d \NC = ut + \frac12 at^2. \NR
\stopmathalignment
\stopformula
\stoptext
Despite "align={left, right}", the first column is aligned to the right and the
second to the left. This does not change, no matter which values I assign to
"align", for example align={middle, middle}.
The align option is also ignored in the case of other column numbers., for
example:
\starttext
\startformula
\startmathalignment[n=1,align=left]
\NC This single column should \NR
\NC be left-aligned, \NR
\NC but it is centered. \NR
\stopmathalignment
\stopformula
\stoptext
What am I missing here? Where is my mistake?

Wolfgang

[NTG-context] Compatibility Issue with TikZ/Spy Library in ConTeXt: Seeking Solutions
Hello,
I am reaching out to seek assistance regarding a compatibility issue I have
encountered after installing ConTeXt on a new computer. The problem arises when
attempting to compile documents that utilize the spy library; the LuaTeX engine
returns the following error message:
"error (luacall): invalid number
mtx-context | fatal error: return code: 1"
Unfortunately, the error message provides no additional clues. To investigate
further, I created a minimal example, which you can easily verify at
https://context-on-web.eu/. The example employs the spy library within a TikZ
environment. Surprisingly, the same example runs without error on my local
LaTeX engine, indicating a potential compatibility issue between ConTeXt and
the spy library.
Here is the minimal example for your reference:
\starttext
\usemodule[tikz]
\usetikzlibrary {spy}
\starttikzpicture[spy using overlays={size=12mm}]
\draw (0,0) -- (1,1) -- (2,-1);
\spy [blue,magnification=5] on (1,1) in node at (3,0);
\stoptikzpicture
\stoptext
I am curious if anyone else has encountered a similar problem with the spy
library and ConTeXt and, if so, if there is a known solution. Any insights or
guidance would be greatly appreciated.
Thank you for your time and assistance.
Best regards,
Wolfgang Backes

Section blocks are intended for that.
Just a comment, if your cover (or title) page involves a one and only
single page, you may use makeups, such as in:
\starttext
\startmakeup[standard][pagestate=start]
\dorecurse{25}{\input knuth}
\stopmakeup
\stoptext
My sample explicitly displays that makeups are intended for a single page.
Since actual content for that makeup would fit in six pages without the
makeup, it looks weird inside it.

If you are showing your code to list members, fine.
Sorry, but if there is a question here, I’m afraid you need to be more
explicit asking your question.
Just some comments:
> %%

In a minimal sample, comments as the previous one don’t provide any clue
to understand your code or the issue you might be dealing with.
It is wiser to keep the sample to its minimal form.

It is better to provide actual content than a file name.
BTW, if its contents cannot be in more than a single page, the approach
suggested above might be easier.

Empty brackets are not required here.

I would say that this is extremely small even for an "x" to fit in.

Hi Miguel,

Some ConTeXt users may also use LaTeX too, but don’t rely on that.

As far as I know, em is defined by the width of the capital 'M' and ex
is defined by the height of the lowercase 'x'.
With your requirements, I think it is easier to set line spacing to one
and a half line with 1.5em, such as in:
\setupbodyfont[termes]
\starttext
\the\exheight\\
\the\dimexpr3\exheight\\
\the\emwidth

Hi Miguel,

I’m not sure whether I’m getting your point here.
See what the difference between not enabling the grid and enabling it:

As said, ConTeXt is \setuplayout[grid=no] by default.
As far as I can recall it, the default value is
\setupinterlinespace[line=2.85ex].
I have just discovered that with values such as line=1.3ex,
\setuplayout[grid=yes] behaves very differently than with values such as
line=2ex (and above).
I mean, lines follow the grid when the text fits. See the difference with:
\showframe\showgrid
\setupinterlinespace[line=1.3ex]
\starttext
\dorecurse{25}{asa aeo eau}
\setuplayout[grid=yes]\page
\dorecurse{25}{asa aeo eau}
\stoptext
According to https://wiki.contextgarden.net/Grid_typesetting (feel free
to improve the article), a way of solving this would be to wrap your
stuff inside:
\startlinecorrection
...
\stoplinecorrection
The problem is that your interline space is too small to prevent line
collapsing.
ex is the height of the lowercase 'x'. Are you sure that your school
doesn’t require 1.3em (height of capital 'M') as interline space instead?
You can get yourself the values:
\starttext
\the\exheight\\
%\the \dimexpr1.3\exheight\\
\the\emwidth
\stoptext
The first line will give you 1ex is about 5.7pt (with the default font
used by ConTeXt). 1.3ex would be less than 6.75pt.
The value of 1em is the value of the font size. Default for ConTeXt is
12pt, so 1em has to be 12pt.
I think it is clear now that an interline space of 1.3ex calls for line
overlapping.
That being said, I don’t know why the grid avoids collapsing them (if
the person explicitly asks for this).

See the wiki article above. The mailing list is also a way of getting help.
One suggestion, please always provide a minimal working sample (that can
be copied, pasted and compiled automatically), when you ask for help.
How minimal? Well, they cannot lack essential parts to be compiled.
Other than that, they should only contain required content to reproduce
your issue.
This minimal working sample helps the one who reads to understand what
you are dealing with.
Otherwise, it is really hard to understand which kind of issue you might
be facing (consider that no one else may read your mind or be in front
of your computer).
I hope it might help,

Many thanks for your explanation, Michal.
I was totally ignorant of the page key in \setupinteraction.
It works fine now, with both the options you provided (and the patch,
many thanks for both).
I have accidentally discovered an issue in which users may run in an
uninteded ways.
If many destinations have the same identifier, only the first one is
generated.
Using the following sample:
\setupinteraction[state=start,
focus=standard]
\starttext
\dorecurse{5}{\dorecurse{5}
{\chapter[\recurselevel]{Chapter}
\section[sec-\recurselevel]{Section}}}
\stoptext
Of course, this kind of identifiers have to be unique to be useful, but
I wonder whether they may be created adding something like:
identifier
identifier-1
identifier-2
identifier-3
…
identifier-n
This way (or a similar one) all named destinations are created.
Of course, when linking with \goto, \in, \at, \about, the right
identifier should be chosen.
With links within the same document, correcting the identifier (or the
link destination) is a trivial matter.
With links from external documents, there may be no option to generate
the external files again. If destinations are there, inspecting the
external document is an option.
Would it be possible that already given destination identifiers could
automatically have another indentifier to generate a new destination?
I hope my explanation is clear. Let me know if it isn’t and I try to
ellaborate it further (in a clearer way ).
Many thanks for your help again,
Pablo

Replying to myself, thanks to the wiki
(https://wiki.contextgarden.net/Commands_with_optional_arguments).
It seems that the command has to be defined as unexpanded, such as in:
\setupinteraction[state=start]
\setupattachments[method=hidden]
\usemodule[database]
\starttext
\unexpanded\def\ItemContents#1#2#3{\doiftext{#2}
{\item {\em #1}\attachment[file=#2, name=\currentitemnumber-#2]%
\doiftext{#3}{ (also available at #3)}}}
\defineseparatedlist
[test]
[separator={,},
quotechar={"},
before={\startitemize[n]},after={\stopitemize},
first={\ItemContents},last={.},
left={\{},right={\}}]
\processdatabasefile[test][context-documents.csv]
\stoptext
It is not clear for me why is this needed, but it might be one of the
many aspects of expansion that average users cannot understand from TeX.

Pablo

[NTG-context] Re: Adobe Source Typescript With Design Sizes
On 10/31/2023 8:18 PM, Vincent Hennebert wrote:
Hello there,
I had mentioned this on a thread some (long) time ago, finally got
around to finishing a first version of a typescript with the Adobe
Source font family, in all its weight alternatives and design sizes (the
latter being available in the Serif style only).
Comments welcome. If it looks good I can upload it to the wiki, on the
Typescripts_examples page I guess.
I have no tiem now to figure out this (somewhat excessive) amount of
fonts - hopefully we will not end up in a world where all fonts have
many weights which makes it easier for designers not to make choices and
delegate that to users instead. That said,
- attached a different approach
- in your variant you can put the lua in the lfg file (at the top) and
then add \loadfontgoodies[...] before where the functions are used
I'm not sure if we can talk of design sizes here. It's more about
'usage' because a display vs subhead vs ... variant is not about mixing
depending on scale (e.g. using display for 20 pt in a 15 pt setup versus
using scaled regular for 20pt and then display 20pt for e.g. a title
page or 50pt on posters).
(I have Questions For the Experts further down...)
maybe a side effect of not defining a math font
About Adobe Source
==
The fonts are available on GitHub [1]. They are the descendants of the
Source {Serif,Sans,Code} Pro fonts described in the type-imp-source.mkiv
typescript available in the ConTeXt distribution. Due to major changes,
Serif Pro was renamed into Serif 4 in, well, its version 4 [2] (that’s
the version that introduces design sizes, a.k.a. optical sizes), and
Sans Pro was renamed into Sans 3 [3].
[1] https://github.com/adobe-fonts/
[2] https://github.com/adobe-fonts/source-serif/releases/tag/4.004R
[3] https://github.com/adobe-fonts/source-sans/issues/192
Usage
=
Short version: store the attached typescript and its helper Lua files
somewhere on your file system where ConTeXt will find them ($HOME/texmf
for example), then use in your document:
\setupbodyfont[adobesource]
Long version: The default typescript name is adobesource (also available
as adobesource-regular) and has design sizes enabled.
Each weight is also available: adobesource-extralight,
adobesource-light, etc., all the way to adobesource-black. There is also
a medium weight, that selects the regular versions of Serif and Sans,
but the medium version of Mono (just slightly bolder than the regular
one, presumably for better on-screen rendering in terminals).
Design sizes can be disabled by adding -nodesignsize- to the typescript
name: adobesource-nodesignsize-extralight, etc.
Finally, I thought it would be cool to over-engineer the typescript a
little bit and provide direct access to the design sizes (in case one
would want a narrower version for body text, or a bolder and more
expanded version for titles, etc.). Here they are, again in all their
weights: adobesource-caption-extralight, adobesource-smtext-light,
adobesource-subhead, adobesource-display-bold, etc. The ‘regular’ design
size is accessed by simply using adobesource-nodesignsize.
Questions For the Experts
=
To avoid a gigantic typescript file with a lot of duplication, I
offloaded the font filename calculation to a Lua function (see attached
adobesource.lua). I initially wanted to put the Lua code inside the
typescript, but then I had all sorts of weird Lua compilation errors.
The very same code works fine when included in a normal document though.
Could it be that typescripts are processed in some special mode that
doesn’t like Lua syntax? As a workaround, I put the code in an external
file and require it from inside the typescript.
In the goodies file, I use what I believe is the largest possible font
size that can be used in ConTeXt (16,383pt) to select the Display design
size. Otherwise, text above that size will fall back to the default,
regular design size.
Now, since I use the goodies file only when design sizes are enabled, I
thought I could make it more robust by using AdobeSource4Display as a
default, that is, for any size above 16.5pt. However, if I mix design
sizes enabled and disabled in a document, the disabled one seems to be
using the goodies file even though it’s not mentioned in the typescript.
Any idea of why? For example:
\usetypescriptfile[adobesource]
\usebodyfont[adobesource]
\setupbodyfont[adobesource-nodesignsize]
\starttext
This text is typeset in Display when Regular should be used.
\switchtobodyfont[adobesource]
This text is typeset in Regular with design sizes enabled.
\stoptext
What’s Next
===
* A harmonious-looking companion math font.
* A harmonious-looking companion math font that uses glyphs from Adobe
Serif 4 when available.

Many thanks for your reply, Hans. I apologize for my poor explanation of the issue. Wanting to give a minimal sample, I didn’t add my full interaction setup: \setupinteraction [state=start, style=, color=, contrastcolor=, display=new, focus=standard] \enabledirectives [references.border=darkgreen] I wanted to be able to setup the interactive link color only, not to add any color to the link text. This would be similar to the following object: << /Type /Annot /A 3 0 R /Border 1 0 R /C [ 0 .6 0 ] /F 4 /Subtype /Link /Rect [ 11.148045 64.22294 29.080798 78.65044 ] >> The "references.border" directive sets all /C keys in /Link objects to one single color in the same document. indeed, because these objects get creates when apage is shipped out and we don't let additional color (or style for tham matter) information travel with the link info I may edit a single file by hand (such as in the attachment), but I won’t be able to do that in a larger PDF source. > Drawing something in the document (avoiding the interactive link border) is not the solution here. you mentioned that you use it for checking so then rendered different whatever styling is reasonable; once you render a final version the single color will do Would it be possible that \setupinteraction could have a bordercolor key, such as the color one? All is possible but not all should be done, especially not features that mostly serve a few viewers (like acrobat) and don't really relate to typesetting. Interaction is key in cases such as the one described, because this kind of interaction avoids two things (or a twofold situation): * Link borders won’t be printed in paper and they’ll be displayed on screen. * This kind of interactivity avoids having to provide recipients with two versions of pretty much the same document (screen and print version). it's one of the nice things about tex that one can easily generate two versions; for screen i'd even make a landscape instead of portrait version and maybe for phones yet another Having to deal with more than one version of almost any documents tends to cause confussion to most people and it eventually leads to errors. Sorry, but I have to keep resulting PDF documents as simple as possible. For their recipients, but this also helps me. but one color will do then in the final document ... multiple for different links / targets is also confusing Of course, one clear objection to my approach is that PDFium (the PDF viewer in Chrome/Edge) doesn’t display annotation borders. indeed There are a handful of PDF features that PDFium doesn’t support (attachments and electronic signatures, to name other two). indeed ... and after decades of pdf that tells a story ... maybe no one using or programming open source viewers care much about it and when different viewers also behave different we end up with endless adaptation and patching which is no fun either In that case, many people understand that PDF (the format itself) is “PDF according to Google” (or “PDF according to Microsoft”, since PDF is opened with Edge by default since Win7). hard to say what is default ... esp when bugs become/became features ... I experience this at work every single day and I’m tired to tell people “please, use Acrobat to display PDF documents and make it your default PDF viewer” (otherwise, it is impossible to know whether a PDF document is electronically signed or not [among other features]). i admit that i never nbother about signed documents; the last time i got some link to an adobe server telling me that i had to sign something i just removed the mail (who knows what they do with your data) Your workaround works best when you have only one medium to handle the document (only displayed on screen). Since it also avoids annotations, it will work with all (or almost all) PDF viewers. Even if a document doesn’t need to be printed now, it doesn’t mean it won’t be needed to print it in the future (so this might give issues in the long run). yes but you wanted it for checking, so then a 'temporary' rendering as mentioned can work ok; it can even be more visible if you use think borders On the general issue here [PDF features only implemented by Acrobat and few viewers], it is a fact Acrobat is only one PDF viewer. But it can be considered the «de facto» standard implementation of the format. with the user interface becoming more horrible every i try to avoid the reader (sumatra works just fine) (viewers in broswers or mail agents can also be weird: currently my thunderbird shows white text on black pages, if at all)

I see that the directive for link borders only allows one color for
links per document.
In my real-world documents, I need to make three different border links:
for destinations inside the document (/GoTo), for destinations in other
documents (/GoToR or /GoToE) and for external destinations (/URI).
With the current document I write now, I have over a hundred links in
twenty pages. Being able to visually distinguish each link helps
interaction with the document (reading or even writing it).
Would it be possible that \setupinteraction could have a bordercolor
key, such as the color one?
All is possible but not all should be done, especially not features that
mostly serve a few viewers (like acrobat) and don't really relate to
typesetting.
That said, we can add some styling. First of all, you can use a bit of
abstraction
\defineinteraction[one] [color=darkgreen,style=\underbar]
\defineinteraction[two] [color=darkred, style=\underbar]
\defineinteraction[three][color=darkblue, style=\underbar]
\def\inone#1{%

\start\setinteraction[two]%
\goto{#1}[url(#1)]\stop}
\def\inthree#1{%
\start\setinteraction[three]%
\goto{#1}[url(#1)]\stop}
which already might help you. To make it easier I'll add \namedgoto do
that one can say:
\def\inone #1{\namedgoto[#1]{#1}[url(#1)]}
\def\intwo #1{\namedgoto[#1]{#1}[url(#1)]}
\def\inthree#1{\namedgoto[#1]{#1}[url(#1)]}
I'll also add \outline and \outlined
\defineinteraction[one] [color=darkgreen,style=\outlined]%
\defineinteraction[two] [color=darkred, style=\outline]%
\defineinteraction[three][color=darkblue, style=\outlined]%
which of course you then will wikify ...
I attached an example but there is no upload (will happen when the build

Is there a way of doing calculations on the coordinates for the draw using

Multiple authors should be treated as multiple authors. That they are
related is not and should not be a consideration in citing works. At
least this is the practice that I know of for academic texts.
You can cheat and try to define one author with a combined first name,
like
author={Eames, Ray & Earl},
but I don't know how that parses as I have never tried it; "and" is a
reserved token used to define multiple authors. I wouldn't do it as I
can think of many examples (Bjaer & Bjaer) where we give both credit,
individually.

[NTG-context] Re: wiki update: Modules
Dear Hraban, When I wrote a class material for Linear Algebra, it is nice to use \pmatrix and \bmatrix etc. But, for example, to write a result matrix of the product of two matrices, I need to calculate it somewhere and copy it to my text. Hence, I tried to use Lua to handle it in the ConTeXt. And, it is nicely working. During the process, I asked many questions to Hans and he gladly helped me. It is the first time for me to code using Lua, so my coding was clumsy. However, Hans corrected it to be usable in ConTeXt even though he is very very busy in many things. And, he made it a module and put it in the list. Thanks Hans. Finally I finished several chapters on Linear Algebra using that code. It was many years ago. Here is a document of it. I confirm that it is running well without any problem. I hope that someone who wants to write an article on Linear Algebra use it. Thanks for reading.

In typo-rep there is also %D \starttyping %D \definefontfeature[default][default][mode=node,formatters=strip] %D \stoptyping You included some notes about Khaled, so I guess he faced the same issue. His Amiri font displays the symbols by default, as do other Arabic fonts. (It seems he never considered making it an opentype feature in the font itself, but since his focus is/was XeTeX/HB (HB is rather rigid and dictatorial) I guess that's not surprising.) I admit that I don't follow what happens with xetex (they changed the rendere at some point indeed) not HB (I only notice that it gets updates frequently in the tex live repository which makes me wonder how one retains compatility unless one freezes). I actually kept the lib binding code that can use it around for your font testing (we wanted to see what uniscribe does), not sure if it still works. Anyway, we're entering the bug cq. side effect becomes feature area here; just like yesterdays perfect bidi algorithm is todays less pefect one replaced by ... But therein lies the problem: ConTeXt shows the rendering by default, and we need to turn it off. Since most non-Latin typography targets Uniscribe applications which allows for toggling, the font developers (commercial or free) don't have to concern themselves with this issue. if context shows it then it is not a feature but hard coded shapes which is weird; how does one know what to 'remove' or not? And in what stage? If they are zero width it is simple to ignore them in the backend, if they have dimensions (w/h/d) then they contributed and wiping is tricky Since Word rules the world, most font designers target it. Since Word provides for toggling the symbols -- needed for editing purposes -- there was no need for Arabic-script font designers to worry about the symbols showing up where they are not wanted. (I suppose that InDesign behaves the same way.) I don't know ... irr these dtp programs are more like "if you want this feature applied select a range of characters and apply it" That's what was meant when I spoke of the continued effects of the WYSIWYG curse: It saved font designers from having to think much about this issue. In some way it's also flaws in the open type approach. Basically that happens when application stuff becomes a standard and one forgets that it was (is) application driven. (And you haven't seen variable fonts and color fonts yet ... no pretty standards either.) Not really -) This brings us to the point of consistency: For Arabic-script fonts, hard symbolic rendering of the Unicode control characters is the rule, not the exception. So not "an inconsistent mess" -- at least not as far as Arabic-script typography is concerned. Funny rules ... but I'm not going top enable 'wipe' by default: after all, one gets what one deserves, nto what one likes (which can differ per day). But you can enable the wiping.

The method appears to work only for nbsp, not zwj etc. Here is the updated MWE: === \startTEXpage[offset=1em] \disabletrackers[typesetters.directions] \disabletrackers[typesetters.zwj] \disabletrackers[typesetters.zwnj] \disabletrackers[typesetters.nbsp] \definedfont[almfixed at 14pt] ZWJ: ZWNJ: NBSP: \stopTEXpage === See attached, please advise. joiners are part of replacement etc and can come and go ... they are characters (we could visualize them but one never knows for sure if one sees them) nbsp are spaces and become glue that we can trace reliable in the node list Many thanks. Ok, here is another MWE featuring a workaround using fallbacks: == \definefontfallback[nosymbols] [file:lmmono10-regular] [200C,200D] [force=yes] \starttypescript [serif] [alm] [name] \definefontsynonym [Serif] [ArabicLatinSerif] \stoptypescript \starttypescript [mono] [alm] [name] \definefontsynonym [Mono] [ArabicLatinMono] \stoptypescript \starttypescript [serif] [alm] \definefontsynonym [ArabicLatinSerif] [file:almfixed] % [fallbacks=nosymbols] \stoptypescript \starttypescript [mono] [alm] \definefontsynonym [ArabicLatinMono] [file:almfixed] [fallbacks=nosymbols] \stoptypescript \starttypescript [almfixed-nosymbols] \definetypeface [\typescriptone] [rm] [serif] [alm] [default] \definetypeface [\typescriptone] [tt] [mono] [alm] [default] \stoptypescript \usetypescript[almfixed-nosymbols] \setupbodyfont[almfixed-nosymbols,12pt] \startTEXpage[offset=1em] \rm ZWJ: ZWNJ: NBSP: \tt ZWJ: ZWNJ: NBSP: \stopTEXpage == Under \rm we get the symbols, and under \tt they are suppressed. Of course it doesn't matter what fallback font one uses, as long as it has no control-character symbols. 1. Can this approach be generalized to get what we want, viz., a way to toggle the symbols? given the inconsistency in what is or is not in a font the only way out is to have our own visualization (consistent across fonts) and even then it would add some mess because we're talking of a mix of characters that can have gone (as part of rendering) or are not characters at all but spacing so, in that case only 'verbatim' is a candidate for visualization, not so much typeset text 2. \enabletrackers[typesetters.nbsp] gives a colored box, which is at least something.. But how can we get the NBSP symbol that's alerady in the font? it's gone by that time ... the line break mmechanism uses glue, not characters 3. Ideally: a. we want all Unicode control symbols to show up in verbatim or in \typebuffer (as in a text editor); only there (with some non interfering rendering i guess) and even then it's probably an additonal pass over the node list b. we want all Unicode control symbols to be suppressed in final pdf output (for, e.g., printing). they basically are unless some font features keeps them around which is out of our control But some fonts meant for printing have symbols for Unicode control chars -- that poses a challenge. so an inconsistent mess not worth wasting time on (as this is hobbyism only fun can be a motivational factir) And some fonts meant for verbatim/editing do not have symbols for the control chars -- that also poses a challenge. AlmFixed, of course, has them. Most minimally decent Arabic fonts have symbols for the Unicode control chars as default, including Scheherazade, Amiri, Uthmanic, and Noto Naskh Arabic -- all free fonts. Industry workhorses like Linotype Lotus (Arabic) also have them. i'm not interested in those .. can't afford them for playing around purposes .. we only look into commercial fonts if we get a dozen unresticted copies for context developers Uniscribe applications like Notepad/Word allow for toggling in a WYSIWYG context -- can't speak for HarfBuzz -- so there is no harm in having explicit symbols in the font. sure, as long as there is no rendering ... they show the input The upshot is that, for non-Latin scripts, some toggling capability in ConTeXt is important to have -- even inescapable for Arabic-script piblishing. a bit subjectiev arguing -) Perhaps others who use Arabic-script or Indic, etc., can chime in..

[NTG-context] rotation weirdness
I encountered something weird, that I cannot explain. It could be an error, but I was not able to pinpoint this.It seems as if the \rotate macro plays havoc with the macro definitions used to set the color of the frame and an outside title.Placing the outside title before the rotate proves that the call to \rotate is the culprit.I enclose an MWE with a little jpeg figure as illustration.

because by default tex loves to duplicate hashes when it serializes
token lists
as this seems to be "the month of the duplicate hashes" i looked it what
we did so far can also work here and i sort of managed although there
might be more cases (when im done with this we probably "have it the
other way around" which could mean adapting some code in the tex-lua
context system that actually depends on duplication or where we work
around it and no longer need to)
the complication is mostly in moving token lists around, them beign
serialized and deserialized etc but i guesa at some point we'll get
there (original tex doesn't really have this problem because there
serialization hashes will triggere errors in cases where they are not
permitted anyway)
no upload as i need to test more

Hi Denis,
this is standard TeX behavior (not only related to XML):
\starttext
\externalfigure[test two spaces.pdf]
\externalfigure[test not two spaces.pdf]
\stoptext
I don‘t know whether this is intended or not.
That being said, more than one consecutive space in a file name (I would
say it) is rather an exception than the rule.
Fixing this may cause more trouble that it might seem at first.
The problem with escaping is that there can be several round trips and
it's kind of hard to predict usage and such. Also, take this:
Then, as i don't have these graphics, the test failed after a catch on
the fact that tex didn't like the string for rendering in the 'unknown
figure' drop in and after another catch the { } were not shown ...
Anyway, with a little magic i can now at least make this work but it
needs testing with existing documents because it's not like we can
update the xml stuff every thiem we have yet another exception (ok,
those using sane image names are probably okay).
So, in a next update you can test some,
Hans
