So this is ok:
\setupfoo
[a=A,
b=B]
\setupfoo
[a=A,
b=B,
]
I'm not aware of funmdamental changes in the parse, apart from that in
many setup commands one can now do this:
\setupfoo
[A=\this[works],
B=\that[doestoo]]
as nested brackets are handled.

\hyphenatedurl only changes the hyphenation of its content, it doesn’t
create a link. In your example it makes no sense.
Generally, you need an anchor (link target) to link to, e.g.
\startchapter[title={My chapter},reference=chap:first]
or
\chapter[chap:first]{My chapter}
This works the same for other structure levels. I’m not sure about
bibliography, but I think you must use the bib entry code.
You can also set anchors manually using \textreference and \pagereference.
Then you can use \in[chap:first], \about[chap:first] or \at[chap:first].
For external links, you use \goto (it’s a bit extensive).
Please look up the syntax reference in the wiki.

[NTG-context] Re: vim syntax highlighting bug?
I was in touch with the maintainer of the context.vim syntax file about
this. It turns out to be an issue with the lua.vim file that is included
in the context one. Lua.vim highlights trailing parentheses as errors,
but that’s done in a way that doesn’t work well when the file is
included by other syntax files. It somehow steals the syntax context and
makes Vim stay in Lua mode when it should go back to ConTeXt mode (I’m
not too savvy of the details).
The maintainer came up with a workaround [1] to force returning to
ConTeXt mode, although the parenthesis remains highlighted as an error.
That highlight bothers me, so my own workaround is to copy the lua.vim
file in my own .vim/syntax folder and comment out the ‘syn match
luaParenError ")"’ line (l.61 in my Vim version).
Maybe playing with the ‘contained’ keyword (in lua.vim) could lead to a
proper solution, but I’m happy enough with my workaround that I haven’t
felt the need to investigate this issue any further.
Hope that helps,
Vincent

[NTG-context] Re: multipage metapost output from ConTeXt
Hi Mikael,
with the solution provided by you, I could work on my graphic which grows from
page to page. So far I have already 28 pages. Now I would like to go back to
the summed graphic of p1 to p21 and add the coming p29, p30 etc. to only that
(that means contents of p22 to p28 should not be visible on pages 29 and
forward).
I don't bother you with my code which is too long. Let's use the mwe provided
by you (I added it here for convenience), where we have 3 pages. How can I have
the content of p2 not be added on page 3 and forward?
\startuseMPgraphic{base}
picture p[];
path TheFrame ;
TheFrame := fullsquare scaled 5in ;
z1 = (60,40);
z2 = (40,90);
z3 = (10,70);
p1:=image(
label("Word 1", z1);
);
p2:=image(
label("Mot 2", z2);
);
p3:=image(
label("Parola 3", z3);
);
\stopuseMPgraphic
\starttext
\dorecurse{3}{ % Frame
\startMPpage[pagestate=start]
\includeMPgraphic{base}
currentime := #1 ;
% Just for learning :

draw textext("T="(currentime)) scaled 2 shifted(0,2in)
withcolor magenta ;
for k=1 upto currentime: addto currentpicture also p[k]; endfor
setbounds currentpicture to TheFrame ;
desiredformat := 1080;% In pixels (will be converted by default at 72dpi)
currentpicture := currentpicture xysized (desiredformat ,desiredformat );

output=\externalfilterbasefile.pdf,
cache=yes,

import graph;
real f(real x) {return sin(x);}
draw(graph(f,-3,3,300),blue);

Using that you could define an asymptote environment so that:
\startbuffer[asymptote-preamble]
\stopbuffer
\starttext
\startasymptote
% Asymptote figure
\stopasymptote
\stoptext
saves the content of the asymptote-preamble and the figure in a separate file,
runs asymptote to generate a PDF figure and includes the figure. The results
are cached so the asymptote is re-run only if the content of the figure
environment changes.
A drawback of this approach is that the labels are generated by asymptote. That
means that the font, colors, and any macros needed for the figures need to be
redefined at both context and asymptote end.

I'm not sure why textstyle=cap fails but textstyle=sc works. However
textstyle=\cap (i.e. as a command) works. Also \abbreviation is already defined
so you don't need to define it again. Thus your MWE becomes:
%\definesynonyms[abbreviation] [abbreviations] [\AbbreviationsFull]
\setupsynonyms [abbreviation] [textstyle=\cap]
\starttext
\contextversion
\abbreviation{NTG}{Nederlandstalige TeX Gebruikersgroep}
Test 1 : \NTG .
Test 2 : \infull{NTG} %\AbbreviationsFull{NTG}.

[NTG-context] \setupsynonyms textstyle=cap failing
Hi all,
the following minimum working example is properly typesetted with
textstyle=bold,
but it fails with textstyle=cap (ConTeXt version : 2023.09.26 18:19)
A number should have been here; I inserted '0'. (If you can't figure out
why I
needed to see a number, look up 'weird error' in the index to The TeXbook.)
mtx-context | fatal error: return code: 1
It works on https://context-on-web.eu (ConTeXt version : 2022.12.22 22:17)
\definesynonyms [abbreviation] [abbreviations] [\AbbreviationsFull]
\setupsynonyms [abbreviation] [textstyle=bold]
\starttext
\contextversion
\abbreviation{NTG}{Nederlandstalige TeX Gebruikersgroep}
Test 1 : \NTG .
Test 2 : \AbbreviationsFull{NTG}.
\stoptext
Any clue ?___

Are you using MkIV (LuaTeX) or LMTX (LuaMetaTeX)?
What’s your ConTeXt version, and how did you install it? (TeX live,
Linux distribution, LMTX distribution?)
I guess a missing EPS means you load the MkIV version of the module,
probably because "m-zint".
Is there an error message with \loadmodule[zint]?
I can’t help with Windows; since Hans developed it on Windows, it should
work (but don’t ask me how).

I will just add to the excellent answers above, that I very much
recommend LMTX and the LMTX way of using the zint _library_. I published
compiled versions of zint and couple of other libraries to the optional
libraries repository:
https://github.com/contextgarden/luametatex-optional-libraries
https://github.com/contextgarden/luametatex-optional-libraries/releases/tag/v20230902
I tested the steps on the wiki and libzint.dll works without problems:
i.e. install ConTeXt, create a few folders, move the dll and
mtxrun --generate.
My goto document for testing zint, that went without problems (even the
hexagons!):
\starttext
\usemodule[zint]
\barcode[alternative=isbnx, text=9783865419026, width=4cm]
\barcode[alternative=qrcode, text={https://wiki.contextgarden.net},
width=3cm]
\barcode[alternative=maxicode, text={test}, width=3cm]
\stoptext
Michal
PS: Coincidentally zint 2.13 has been released just today. Usually every
new zint release requires an update on the ConTeXt side, but older
releases still work well with ConTeXt (e.g. currently ConTeXt supports
2.10, 2.11 and 2.12). The version linked above works.

Hello ConTeXters,
I wrote a little ConTeXt module for drawing globes. I would love some advice on
how to improve it and share it. The code is quite short (about 250 lines). Most
of the work is done by Lua, which reads the data files and calculates paths.
These paths are passed to MetaFun, which draws the globe.
about names:
how about
t-luageo.lmt
t-luageo.mpxl
so that one knows what comes with the module (we do the same with s-*
modules)
and you can add the example to the end of the module
\continueifinputfile{t-luageo.mkxl}
\starttext
exaple code
\stoptext
and then process the module to get the example

Try the following version of your example which incoporates Hraban's and

Also take care over changing style so use \bold{this is bold} or {\bf this is

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.

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

When you have a single linenumbering block in your document you can set
the left/right values at the begin of your document with
\setuplinenumbering[left={[},right={]}]
When you have multiple linenumbering blocks in your document you can
ensure the values stay also on the last page with a forced page break before

I'm reading this thread and I'm interested because I type a lot of
text with mathematical formulas.
In fact, I find that \dfrac{} creates unsightly leading space and that
\frac{} is too small. What is the difference between \frac{} and

\frac switches the math style while \tfrac (textstyle), \dfrac

Let me ask you another thing, how can I avoid messing up the
line spacing by using \sqrt and \frac, the line that follows these has increased
line spacing in the pdf output
code:
Find the normal and shearing stresses on an oblique plane defined by
$l=\sqrt{\frac{3}{13}}$, $m=\sqrt{\frac{1}{13}}$, and $n=\sqrt{\frac{9}{13}}$.
Complete working minimal examples are preferred over code snippets.
To avoid single lines with different spacing you can either increase the
line spacing for all
lines with \setupinterlinespace or you use a different fraction command
which uses
smaller numbers or creates inline fractions.

in my ConTeXt book, some examples for \framed with rounded corners look
odd, as if the MetaPost calculation of rounded corners fails.
I can’t find a minimal example that shows the problem, and I can’t
imagine which of the settings in my extensive environment would cause it.
Find below the code that works on its own, but causes the results as
shown in the attachments within my book. There’s nowhere a \setupframed,
and nothing that should influence MetaPost.
Do you have any clue for what I should look?

[NTG-context] Re: \unit{mercury} renders as m (meter) and \unit{millimetermercury} doesn't work as expected
Marco Patzer schrieb am 05.12.2023 um 15:19:
Hi!
I'm struggling with the rendering of a particular liquid metal:
%% renders as m (meter), not as Hg
\unit{mercury}
%% renders as mm·m, not as mmHg
\unit{millimetermercury}
This is strange, since both “mercury” and “millimetermercury” are
defined in phys-dim.lua. To get mercury recognised as a unit this
can be used:
\registerunitshortcut [mercury=mercury]
Now \unit{mercury} renders correctly as Hg.
Why is that \registerunitshortcut necessary? Is it even correct to
use it like this? However, even then millimetermercury doesn't
render correctly:
%% renders as mm·Hg, not as mmHg
\unit{millimetermercury}
How to get millimetermercury render as mmHg? And “inch mercury”
render as inHg? I can't find “inchmercury” in phys-dim.lua, only
“millimetermercury”, should it be added?
Example:
%% \enabletrackers [physics.units]
%% inch should render as “in”
%% \setupunittext [inch=in]
\starttext
\unit{mercury}\crlf %% renders: mm · m
\unit{12 millimetermercury}\crlf %% renders: mm · m
\unit{12 inchmercury}\crlf%% renders: in · m
%% why is this necessary to get mercury rendered as Hg?
\registerunitshortcut [mercury=mercury]
\unit{12 millimetermercury}\crlf %% renders: mm · Hg
\unit{12 inch mercury}\crlf %% renders: in · Hg
\stoptext
Questions:
1) Why is \unit{mercury} not working, although it's listed in
phys-dim.lua?
2) Is the call \registerunitshortcut [mercury=mercury]
necessary/correct?
3) How to make \unit{millimetermercury} render as mmHg and
\unit{inch mercury} render as inHg?
None of your examples work because millimetermercury and mercury are the
names for the labels
and the units are accessed with hg and mmhg.
\setupunittext[en][millimetermercury=inHg]
\starttext
\unit{mmhg}

What are you using for links to external documents? If just a single command
such as \goto then you might be able to get away with defining a wrapper (e.g.
\myGoto) that does \setupinteraction[state=start,page=name,focus=standard] then
the \goto command then \setupinteraction[state=start,page=fit,focus=standard]
afterwards.
(Assuming calling \setupinteraction that many times does not cause problems in
itself.)

Sorry, Hans, if I am missing the point.
Does the above mean that ConTeXt will be able to sign PDF documents with
digital certificates?
Well, that's what singing is, right? The problem is actually less in the
signing than in the certificates themselves.
Basically one can sign (with some certificate) and then validate.
% sign-001.tex
\setupinteraction[state=start]
\definefield[signature][signed]
\defineoverlay[signature][my signature]
\starttext
\startTEXpage[offset=1ts,frame=on,framecolor=darkblue]

{\fieldbody[signature][width=3cm,option=hidden]}
\stopTEXpage
\stoptext
after neing processed:
mtxrun --script pdf --sign --certificate=sign-001.pem --password=test
sign-001 (--library)
and:
mtxrun --script pdf --validate --certificate=sign-001.pem
--password=test sign-001 (--library)
etc. works here.

IIRC width=fit is intended for presentation styles because it uses

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,
I don't know if \startMPinclusions \stopMPinclusions shall work with
\startMPpage and \stopMPpage. In this case, one can use a separate
graphics:
\startuseMPgraphic{base}
picture p[];
path TheFrame ;
TheFrame := fullsquare scaled 5in ;
z1 = (60,40);
z2 = (40,90);
z3 = (10,70);
p1:=image(
label("Word 1", z1);
);
p2:=image(
label("Mot 2", z2);
);
p3:=image(
label("Parola 3", z3);
);
\stopuseMPgraphic
\starttext
\dorecurse{3}{ % Frame
\startMPpage[pagestate=start]
\includeMPgraphic{base}
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: addto currentpicture also p[k]; endfor
setbounds currentpicture to TheFrame ;
desiredformat := 1080;% In pixels (will be converted by default at 72dpi)
currentpicture := currentpicture xysized (desiredformat ,desiredformat );
\stopMPpage
}
\stoptext

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 );
\stopMPpage
}
\stoptext

[NTG-context] Re: multipage metapost output from ConTeXt
Hi Emanuel,
I am not sure I understand your question, and since you use fonts that
i do not have, I cannot test your example as is. But, maybe, if you
want to redraw a picture, you can do
addto currentpicture also p1;
where you want it.
/Mikael
PS For the text thing, I did not get it. Could one have a _very
simple_ example showing only that problem and no other problem?

You didn't specify the color of path A in p2 and p4. So it's drawn in black.
The other issue, I can't help.

So is there a way to circumvent these issues? Or an explanation for this
behavior, so that I can try to find a solution by myself?

True, thanks for pointing that out. I wasn't aware and frankly,
that's rather unexpected behaviour.
So to put it all together, this now works for me:
\definefontfamily [mainface] [rm] [TeX Gyre Pagella]
\definefontfamily [mainface] [ss] [TeX Gyre Heros]
\starttypescript [math] [default] [size]
\definebodyfont [8.5pt] [mm] [default]
\stoptypescript
\definetypeface [mainface] [mm] [math] [pagella]
\setupbodyfont [mainface, 8.5pt]
\starttext
\math{V_y}
\bold{\math{V_y}}
\stoptext
Thank you for your replies.

Hi!
I have a strange issue when TeX Gyre Pagella Math is used together
with bold text. MWE:
\definefontfamily [mainface] [rm] [TeX Gyre Pagella]

%% comment/remove this line and it works

\stoptext
The error is:

[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
Hi,
try
\startmathalignment[n=2,align={1:left,2:right}]
I think this was changed two or three years ago.

[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?
Regards
Wolfgang

[NTG-context] Re: Compatibility Issue with TikZ/Spy Library in ConTeXt: Seeking Solutions
On 11/24/2023 11:17 AM, wolfgangbackes--- via ntg-context wrote:
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.
the log probably mentions some call lua issue .. tikz is somewhat hard
to debug but in the end i figured out that it relates to the way it
registers function where it assumes that it's the only pqackage in the
tex universe
put this before you load tikz:
\ifdefined\pdfstrcmp\else
\def\pdfstrcmp{\directlua{
local a = token.scan_string()
local b = token.scan_string()
context((a < b and -1) or (a > b and 1) or 0)
}}
\fi
i'll add more efficient ones to the tikz modules
