[NTG-context] nbsp in XML (S01E01)
Dear list,
first episode of series on nbsp of XML in lmtx.
Unfortunately, not that catchy as Netflix.
Used XML input has two types of non-breakable space:
- unicode character
- html entitity (in fact an ugly output of HTML editor)
HTML is preprocessed with ctx preprocessor (great feature!) and substituted
for unicode char nbsp or tilde.
MWE shows unichar spaces are non-breakable (see end of the first lines),
however they are not stretchable (see second line of the paragraphs).
Does unicode nbsp have fixed with in ctx?
When tilde is the replacement in preprocessor (uncomment first replacement
in preprocessor), xmlfush will display tilde (which is, as character,
non-breakable and unstretchable, no surprise).
Why tilde is displayed?
Replacing or adding nbsp (tilde) with finalizers have different results,
see next episode after this one is understood.
Thank you,
Jano
MWE (rather use attached file not to loose invisible characters):

[NTG-context] lmtx update: two experimental features
Hi,
I uploaded a new version. There are two new features that are
experimental. This time we attempt to deal with the more tricky things
and artifacts of the otherwise nice tex machinery we need to get rid of.
One can rightfully argue that they are not really issues as one can work
around them (and so they are never brought to attention) but why not
make things better (cleaner) if we can.
(1) Languages: hyphenation normally uses a hyphen and the engine has
some messy work-around-border-cases in the hyphenator. So, I wondered if
we could improve that.
First of all, there can now be more than one hyphen character so here is
the way to deal with it (the hyphenchar code is like the other 'codes'):
\hccode"002D = "002D
\hccode"2010 = "2010
\hccode"2013 = "2013
\hccode"2014 = "2014
This makes all these four into (kind of) compound word seperators:
\startTEXpage \hsize3mm
firstpart\char"002D secondpart\blank
firstpart\char"2010 secondpart\blank
firstpart\char"2013 secondpart\blank
firstpart\char"2014 secondpart
\stopTEXpage
will work ok. There are provisions for those characters being at the
left and right edges. All is under low level (engine) option controls
(compatibility and such) but currently I enable all. With a bit of
definitions one can for the 002D and 2010 cases deal with pre/post
variants .. the question is do we need that for more, if so, then I need
to add some more code (doable).
This feature relates to Denis collection of German compound words and
ligature prevention data. Dutch has the same issue. (Denis: we can ditch
the compound word entries now, the ones with -.)
Also, this kind of automatism (keep in mind that normally tex won't
hyphenate the first word in such a compound) is especially handy in
cases where there is no control over the input as with xml (when we do
have control you can use || as compound word marker).
(I'm wondering if we should deal with the typical somewhat archaic tex
-- and --- in a different manner, but I'll come back to that.)
(2) Math: what is added is not so much an issue in traditional tex math
usage which is for journals but as context is used for educational
purposes and thereby has quite some tricks built in. Some of these jump
through ugly hoops to get it done. Here I stick to color as example.
Just try this (notice the spacing):
\startTEXpage[offset=10pt]
\showmakeup[mathglue]%
\enableexperiments[simplegroups]%
$ a = b \color[red]{=} c \startcolor[blue]=\stopcolor d $\par
$ \sin \color[green]{(x)} = \sin {(x)} $\par
\disableexperiments[simplegroups]%
$ a = b \color[red]{=} c \startcolor[blue]=\stopcolor d $\par
$ \sin \color[green]{(x)} = \sin {(x)}$\par
\stopTEXpage
The 'simplegroups' experiment enables a more hybrid grouping model but
we (read: Wolfgang, Aditya and I, but input is welcome) need to check
for side effects carefully.
The 'mathglue' tracker is also new, and it exposes what actually goes
on. It has to do with the fact that something grouped with { } creates a
math list which enforces different spacing but in the case of color that
is a side effect we don't want (of course it relates to how context
implements the \color macro and one could work around it, but the
problem is of a more general nature.

[NTG-context] braces removed in url
Dear list,
I have the following sample:
\setupinteraction[state=start]
\starttext
\startTEXpage[offset=1em]
\def\MyURL#1{\goto{\hyphenatedurl{#1}}[url(#1)]}
\MyURL{a={b}}\\
\MyURL{a=\letterleftbrace b\letterrightbrace}\\
\asciimode\MyURL{a={b}}\\
\stopTEXpage
\stoptext
For all three options, destination is a=#b. Both with MkIV and MkXL.
What am I missing to get the destination a={b}?
Many thanks for your help,
Pablo

[NTG-context] metafun / patterns
Hi,
As I'm still in metafun (and svg) mode I decided to support patterns
(that are already supported at the tex end) also in metafun. As there
has never been demands I suppose it's not that interesting but it sort
of fits in.
There are some tricky aspectx involved so the interface might evolve a
bit (some more control options) but here are some examples anyway:

[NTG-context] TEXpage does not fit \placetable & \recurselevel always zero
Dear list,
thank you very much for the help so far.
I have two problems understanding the output of the code below. I am using
version 2021.02.23 17:47.
(1) The TEXpage is cut off after ~40 lines. Normally, the page is extended to
fit its content. It's probably related to \placetable which I only use here
because I need a centered table. I can set the height of the page manually, but
the whole purpose of using TEXpage was to avoid that.
(2) \recurselevel is always zero in the output. Normally, it counts the
iterations. This issue is not relevant for my actual use-case, but I found that
when writing the MWE.
Best wishes,
Jacob Kauffmann

Re: [NTG-context] Arbitrary equation tags... again
I found a workaround for anyone interested:
\setupinteraction[state=start,focus=standard]
\starttext
\startplaceformula[title=$\alpha$,reference=alpha]
\startformula
1 + 1 = 2
\stopformula
\stopplaceformula
\dorecurse{20}{\samplefile{knuth}}
I'm in \in{$\alpha$}[alpha] %so the reference is now visible
\stoptext
However, one has to manually write a label and a title independently, so
I'm not sure that's a clean solution...

You get what you ask for: different text ends up at the left or right
edge depending on the reverse.

[NTG-context] lmtx
Hi,
In the last couple of lmtx uploads \startTEXpage should work a bit
better. These uploads also introduced a new option for alignments, which
can be checked in:
\def\DemoA#1{\vbox{\red \hsize#1\input tufte }}
\def\DemoB#1{\vbox{\green \setupalign[always]\hsize#1\input tufte }}
\def\DemoC#1{\startTEXpage[offset=10pt]\DemoA{#1pt}\blank\DemoB{#1pt}\blank#1pt\stopTEXpage}

\the\dimexpr#1pt\relax
\stopTEXpage
}
\DemoC{370} \DemoC{390} \DemoC{490} \DemoC{540} \DemoC{580}
\stoptext
I leave it to users to determine if the few cases where the results
differ are better or worse but one can for instance use it to influence
(as side effect) the last line. In general, tweaking the machinery can
give different results and i guess that hardly any user can make
consistent claims about what is better. It all depends on what one deals
with.
(The keyword is suboptimal, it kind of tells what happens but on the
other obscurew what really goes on: always forcing a first hyphenation
pass when breaking lines.)

Re: [NTG-context] set fallback in \definefont
Thanks for the quick response, Pablo. I already use typescripts
(\definetypeface, \definefontsynonym and \definefontfallback):
https://github.com/bateni/dabeer/tree/master/texmf-local/tex/context/fonts/mkiv
By arbitrary style, I meant something like:
\definefontfamily[myface][CUSTOM][TeX Gyre Pagella]]
https://wiki.contextgarden.net/Font_Switching says fontstyle is rm, ss, tt,
mm, hw, cg, ...
Because the the three dots at the end, I thought it would be possible to
define new fontstyles. But I get an error if I do so.
So I usually use \definefont to set up one-off fonts for specific use-cases
such as special headings or an artwork, etc. I was wondering if I can
easily apply fontfallbacks for those.

Hi Mohammad,
the simplefonts module has been deprecated, since it has been
implemented in the ConTeXt core (see below).
\definefontfallback might be the command you are looking for.

The new commands are \definefallbackfamily and \definefontfamily.

\definefallbackfamily

I’m afraid that I’m not sure whether the following sample contains your

[mainface]

[TeX Gyre Pagella]

\setupbodyfont[mainface]

I hope it helps,

1. Because the letters have different heights.
\startTEXpage[offset=1ex]

A pity. I didn’t understand that from the documentation.
That means I need to setup different filters for internal and external graphics
with the same content.

That would solve this problem for me and would make the behavior of filter
commands more consistent.
OTOH I can understand you don’t want to bloat your module.

I don’t see this as an option, as we try to avoid code duplication over
hundreds of graphics snippets.
The \start/stop environment, as well as external files, should just contain the
TikZ commands. All common setup/teardown code belongs in extra files/buffers.

I can understand that.
I should probably let filter call an external script, or fork t-filter for my

The current auto-generated file names are uncomfortably long, and I’d like to
know which contains what.
I’m not yet sure what would make the most sense for this project (at least
sorting by chapter/component would), but I have an use case with LilyPond where
I could save several LilyPond compile runs if I could influence the naming:
I got ~500 songs in their own component files, and I use them in different
songbooklets with the same layout. E.g. there’s one containing all the songs
and several with a subject (e.g. winter & christmas, children, medieval &
fantasy, some author...).
They all use [name=\currentcomponent]. If I could avoid the JOBNAME part of the
file name, all booklets would use the same note PDFs. Now, the temp directory
contains literally thousands of files.
Since this is just for fun, the additional space and compile time is just a bit
annoying and doesn’t affect others, but I like to streamline my workflows...

Ah, I didn’t look closely enough. Thank you, that’s an usable workaround.

For \processFILTER, t-filter does not even read the file... so it has to do
with how the filtercommand is defined.

It does not. As I said, for processing external files, t-filter does not even
read the file and just takes care of caching the result. It is assumed that the
filter command can process the external file.
I can see if it is possible to active before and after filters while processing
external files. Another option is to write the external files as valid tex file
(i.e., with a \startTEXpage .. \stopTEXpage wrapper), and when defining the
filtercommand, use something like `context --environment=env filename`, where
env is the environment file with all the settings for fonts etc.

Caching should work if \definefilter is configured correctly.
From the point of view of t-filter module, this is a bug in the external
program and you should contact upstream for a fix :-) Most (all?) other
programs are happy to write a file in any directory (modulo write permissions,
etc.). I do not want to increase the complexity of the module to handle such
corner cases.

Re: [NTG-context] filter module / externalizing TikZ graphics
Still working on that.

I’ll add these issues to the tracker of t-filter, if it makes sense.
Testing with: ConTeXt ver: 2021.01.24 16:07 LMTX fmt: 2021.1.25
The setup below works, but only with \starttikz ... \stoptikz so far, I don’t
like the output file names, and using the working directory is tricky.
(1) \processFILTERfile
\processtikzfile{img/example.pgf}
can’t find the file:

Rerunning filter
t-filter> file 'tikztemp/example1.pgf.pdf' cannot be found

Looks like ConTeXt can find the file, but the filter module cannot.
--trackers=resolvers.schemes (or \enabletrackers) doesn’t change anything WRT
log/output.
Since this fails already, I don’t know if \processFILTERfile also uses
bufferbefore/-after (it should).
(2) working directory
Since ConTeXt can’t put generated (temporary) files into a directory and
--result also only renames afterwards, the directory key doesn’t help, I had to
add "mv" and "cd" to my filtercommand.
I didn’t check yet if caching works.
(3) file names
Using \processFILTERfile the original file name base is preserved, according to
the log entry above.
If I use \starttikz[name=example], I get "JOBNAME-temp-tikzThick-example.tmp".
I’d like to get something like "COMPONENTNAME-##-example.tmp" or a path like
"COMPONENTNAME/example_##.tmp".
Is there a configuration hook in the module to change name generation?
(4) subprocess parameters
I’d like to forward some parameters from \starttikz to the temp buffer, e.g.
\starttikz[name=example][mystyle=thick]
(using the same syntax as \startsection with a second pair of brackets for
custom parameters).
And then have
\starttikzpicture[\filterusersetupvariable{mystyle}]
in the buffer.
My workaround so far is a copy of the filter setup (tikz/tikzThick), since we
have only a few different configurations.

Yes. The problem is that in order for auto width to work we need to have

It is not only the tikz setup; you also need to copy the font setup etc.
\typesetbuffer[setups,figure]
or some variant of that should also work. But the filter module does make it
easier to store the results in another directory so that they are out of sight.

Hi,
did anyone succeed in externalizing TikZ graphics with ConTeXt?
It’s about a project with hundreds of diagrams that (in the current state)
clutter the main directory with cryptically-named PDFs (at least sorted by
component name) and that on each ConTeXt run take a lot of runtime (I guess
also the many log lines slow the process).
In 2013, Aditya said it wasn’t possible to externalize pgf/TikZ graphics as documented in
the pgf manual, and "perhaps" it would make sense to use his filter module:
https://mailman.ntg.nl/pipermail/ntg-context/2013/071162.html
Did anyone try to do that? I didn’t find anything in this list’s archives.
The original pgf way is two-pass, and you’d need to call LaTeX with the
intended graphics name as --jobname; that’s far too much of a hassle for that
many graphics.
I generally like how the filter module works, as you can also define the name
of every buffer, but my only experience with that is my LilyPond setup.
If nobody has better advice, I’ll try to come up with a filter setup. That
would mean we’d avoid the tikz module, every TikZ diagram will get written to a
buffer of configurable name, and that (with preamble setup) will get run
through LaTeX. I read pgf had some restrictions in plain TeX mode, but perhaps
we can also use LuaTeX in plain mode to avoid the LaTeX dependency.
In the following case the buffer only gets typeset when it changes:
\starttext
\startbuffer[foo]
% maybe include a style / enviroment
\usemodule[tikz] \usetikzlibrary[patterns]
\startTEXpage
\starttikzpicture
\draw[pattern color=red,pattern=bricks] (0,0) circle (1cm);
\stoptikzpicture
\stopTEXpage
\stopbuffer
\framed[offset=overlay]{\typesetbuffer[foo]}

[NTG-context] new font trickery
Hi Jairo,
(to the list for those who want to play with it)
In addition to the metapost fotn subsystem I also made a tex variant.
That one is currently based on setups. So, we now can use mp as well as
tex to make fonts. Of course this is mostly for special purposes and for
fun but both are quite efficient.

[NTG-context] lmtx upload
Hi,
I uploaded a new lmtx. Nothing spectacular as I'm still playign with
compact font support (as explained in previous mails). Most seem to work
now.
New magic:
\startTEXpage[offset=10pt]
\vl\glyph `M\vl\quad
\vl\glyph raise 3pt`M\vl\quad
\vl\glyph left 3pt`M\vl\quad
\vl\glyphright 2pt`M\vl\quad
\vl\glyph raise -4pt right 4pt`M\vl\quad
\vl\glyph left -1pt right -1pt`M\vl
\stopTEXpage
This is part of some experiments with manipulating glyph dimensions
instead of font kerns. These extensions will stay (who knows when it
comes un handy) but we will probably stick to font kerns as default.
\startTEXpage[offset=10pt]
\showfontkerns
\showglyphs
\strut average\par
\vskip-2ex
\enabledirectives[fonts.injections.method=advance]
{\red \strut average}\par
\stopTEXpage
Both methods have their pros and cons.

Really? I wouldn't see it this way. I wondered a bit about the

I have calculated the number of primitives from the list made in "TeX
Reference Manual" by David Bausum (of which there is a web version at
https://www.tug.org/utilities/plain/cseq.html).
According to that text the number of primitives is exactly 326. In my
document I rounded it to "approximately 300".
That list is a bit old. In the meantime we got etex extensions, which
adds a few more, and then pdftex ades some, as well as omega and after
that of course luatex. In luametatex we dropped some, and added others,
so there we currently have 770 primitives. The increase of number is
partly due to the 166 extra math related primitives of which many deal
with all kind of font related paraneters and inter-blob spacing.

if yuou want to know if something is a primitive, say:
\meaningfull\vskip \par
\meaningfull\relax \par
\meaningfull\framed\par
and you get an idea (\meaningfull itself is a primitive, the more
verbose \meaning, and there's also \meaningless which I let you figure
out yourself; of course these add two primitives to the repertoire).

You need "script=auto" (or a valid argument for the script key) in your
font features for the monospaced font.
Another option is to use "features={always,standarddigits}" but this
enables kerning and ligatures.

Hi Jairo,
the sample can be much simpler:
\starttext
\startMPcode
draw textext("some text");
\stopMPcode
\stoptext
This might be related to the issue that I reported about text scaling in
lmt_followtext

Hi Bruce,
here you have a sample:
\setuphyphenation[method=traditional]
\registerhyphenationexception[en][re-im-ple-men-ta-tion]
\starttext
\startTEXpage[offset=1em]
\hyphenatedword{re-implementation}\\
\hyphenatedword{re||implementation}\\
\hyphenatedword{re--implementation}\\
\hyphenatedword{reimplementation}
\stopTEXpage
\stoptext
If you comment the first line, only "||" allows hyphenation.
I hope it helps,
Pablo

[NTG-context] problems with signature fields
Hans, I have the following sample: \setupinteraction[state=start] \starttext \startTEXpage[offset=1em] \definefield[x][signature] \field[x] \stopTEXpage \stoptext I can only use Acrobat to sign PDF documents with signature fields generated by ConTeXt. Other tools sign the PDF document not producing a valid signature (Acrobat cannot read or validate it). From the source, signature has two objects (copied from the sample above): 2 0 obj << /DA (/rmtf 11.9552 Tf 1.1955 Ts 0 0 0 rg 0 0 0 RG) /DV /F 4 /FT /Sig /Ff 0 /Kids 1 0 R /MaxLen 1024 /Q 0 /Subtype /Widget /T /V >> endobj 4 0 obj << /Type /Annot /DA (/rmtf 11.9552 Tf 1.1955 Ts 0 0 0 rg 0 0 0 RG) /F 4 /Parent 2 0 R /Q 0 /Subtype /Widget /Rect [ 14.033054 14.033054 70.40415 25.08072 ] >> endobj One of the tools that has issues with two objects for the signature field is the latest version (1.18) from mupdf-gl. mupdf-gl adds the signature value to the child (object 4) and not to its parent (object 2). I’m afraid this is also the same issue that AutoFirma (a e-signing tool developed by the Spanish government [https://firmaelectronica.gob.es/Home/Descargas.html]) has with these signature fields. When both objects are merged in one (as Acrobat Reader does when saving a copy), both tools generate documents contaning signatures totally unproblematic to be read validated by Acrobat. I suggested merging both objects back in 2017. You told me that simplifyng this would introduce too much complexity in ConTeXt only to save some bytes. Back then, I thought it was an minor improvement. Now I realized that this two objects for signature fiels are only valid for Acrobat. I wonder whether this improvement might be also easier to make in LMTX. Would it be possible that signature fields may have only one object, so that mupdf-gl and other tools have no problem signing fields PDF documents generated by ConTeXt?

[NTG-context] store data in the first run for later runs?
Dear list,
I have the following sample:
\starttext
\startTEXpage[offset=1em]
\startmode[*first]
\startluacode
io.write(" What’s your name?")
document.user_name = io.read()
document_data = { "\\def\\UserName{" .. document.user_name .. "}" }
io.savedata(tex.jobname.."_document-tmp-data.txt", document_data)
\stopluacode
\stopmode
\input{\jobname_document-tmp-data.txt}
\UserName, nice to meet you.
\stopTEXpage
\stoptext
This prompts user input on the first run, but I have to save to an
external file to be able to read it in next runs.
Just in case you might wonder, the actual code requires "--purgeall".
Is there no way to save that in the .tuc file for later runs?
I have tried
https://wiki.contextgarden.net/System_Macros/Key_Value_Assignments#Multi-pass_data
(as Aditya suggested to me), but runs after the first one see to empty
the data in the Lua table.
Adapting a sample from the wiki:
\starttext
\definedataset[somedataset]
\startmode[*first]
\setdataset[somedataset][wantscake=yes, wantsdeath=no]
\stopmode
Do you want cake? \datasetvariable{somedataset}{1}{wantscake}.\\
BTW, do you want death? \datasetvariable{somedataset}{1}{wantsdeath}.
\stoptext
I wonder whether there is no cleaner way to do this.
Many thanks for your help,
Pablo

Many thanks for your reply, Aditya.
Your approach is really interesting, but I don’t know how to mix it with
the first run mode.
\startmode[*first]
\startluacode
io.write("\n\n Document URL?")
document.url_address = io.read()
\stopluacode
\definedataset[document_data]
\setdataset[document_data]
[url=\cldcontext{document.url_address}]
\stopmode
\starttext
\startTEXpage[offset=1em]

\stopTEXpage
\stoptext
How could I make this sample or a similar approach work?
What I need it to avoid entering the same address more than once.

Re: [NTG-context] numbering pages included by \copypages
After further testing guided by Hans’ suggestion, I now have
\setupexternalfigures[location=default]
\setuplayer[preset=rightbottom, method=overlay]{}
\setuppagenumbering[color=darkmagenta]
\starttext
\getfiguredimensions[HannahBW.pdf]
\dorecurse{\noffigurepages}{
\startTEXpage[pagestate=start]
\layeredtext[]
[boffset=3pc, roffset=3pc]
{\darkmagenta\subpagenumber}
{\externalfigure[HannahBW.pdf][page=#1]}
\stopTEXpage
}

which works, though it would arguably be better if there is a way to
prevent the subpage number on the first page of every included file.

Congratulation for your excellent work, Garulfo.
Your translation is really amazing.

The default is "indentnext=no" for \setupheads and \setupfloats.
The pattern is clear: see what comes before the unindented paragraph.
BTW, I don’t understand this:
\langueprincipale[fr]
\langue[fr]
Is \mainlanguage not enough? (This would also set \language.)
\mainlanguage[fr]

Re: [NTG-context] Fwd: Continued fractions in ConTeXt
I've just tested it and it looks w a y better than before (thanks!). Btw,
where could I read about key-value pairs for ConTeXt fractions
(\definemathfraction)? I've seen keys like "threshold" and other weird ones
in the command list, so I ask about a reference (maybe somewhere in a
manual; the Garden doesn't say a lot about it). Thank you very much.
Sincerely,
Jairo :)

[NTG-context] Fwd: Continued fractions in ConTeXt
Hi list! I've tried adapting the following code for continued fractions:
%https://tex.stackexchange.com/questions/73195/how-to-typeset-a-continued-fraction-in-the-following-format
\documentclass{article}\usepackage{amsmath}
\begin{document}\newcommand*{\cofrac}[2]{%

\genfrac{}{}{0pt}{0}{}{#1+#2}%
}%}\[
a_0 +
\cofrac{a_1}{
\cofrac{a_2}{
\cofrac{a_3}{
\genfrac{}{}{0pt}{0}{}{\ddots}
}}}\]\end{document}
As I could read from the mailing list, ConTeXt no longer supports
\genfrac, so I've tried
the following using \definemathfraction
\definemathfraction[gefrac][cfrac]
\setupmathfraction[gefrac][rule=no]

Mmm, superscripts and fraction rules superpose, so indeed something is
wrong. Any ideas or references to a better result?
I've attached the expected result (it's from Legendre's Théorie des
nombres) and a normal fraction for comparison.
Thank you very much.

[NTG-context] Extra space when \setcharacterkerning is used in enumeration
Hi,
I noticed an extra space in an enumeration when
using \setcharacterkerning in the \headstyle parameter. The extra space
appears before the first word "Sats", and in my case it is unwanted (In the
example I want the word Sats to align with a), b), ...).
The space was not there a year ago, with the same code.
In the test file below (sorry for its length), the environment sats is
having the problem, while SATS does not. The only difference is in the
\headstyle parameter.
Am I missing something obvious?

square roots and fractions seem to be gone.

Hi,

put this in cont-new.mkiv:

{\noexpand\triggermathstyle{\number\normalmathstyle}%

but next upload test again (as i'm experimenting with it a bit just for

Hi Alan,
Sorry, I should have actually tried your MWE. You do *not* want
way=bypage here, as that resets the counter to one at the start
of the next page (it is useful for footnotes that are numbered
per-page, but not for actual page counters).

Re: [NTG-context] problem with counters (page)
Hi, Taco—
Thanks for the suggestion. I have tried it with \incrementcounter before
and after the TEXpage. Sadly, neither worked.
This mwe is an attempt to capture the failure of the following in
processing a product with numerous components:
\definecounter[volpage][type=page, way=bypage]
\setupfootertexts[text]
[]
[{\centerline{\raise\NumberRaise\hbox{\rawcounter[volpage]}}
\incrementcounter[volpage]}]
[{\centerline{\raise\NumberRaise\hbox{\rawcounter[volpage]}}
\incrementcounter[volpage]}]
[]
If your suggestion had worked, I would have had difficulty in applying it.

[NTG-context] problem with counters (page)
My efforts to set up a new page counter in the footertexts of a book are
not proving successful. The following code shows the nature of the problem.
\definecounter[volpage][type=page, way=bypage]
\starttext
\setcounter[volpage][5]
\dorecurse{3}{\startTEXpage[offset=2pc]
\input ward
\blank[medium]
\centerline{\red\tfa\rawcounter[volpage]\incrementcounter[volpage]}
\stopTEXpage}
\stoptext
As you will see, the counter is not incremented on pages 2 and 3.
I expect that I have missed something important. But what?

Dear all,
with your help I can colorize the empty even page right before a
chapter starts
on the odd page. The mwe below shows it.
Now I would like to redefine the contents of the left page on the fly
in the text
so that I could place images on this page.
I thought that I could get a simple solution by inserting a TEXpage as
even
page, but this does not work for several reasons. First a TEXpage is
not counted
correctly like a normal page. And secondly I found now way to put it
on the
even page.
So what I really want to achieve is a way to redefine this setups at
some point
in the text to insert eg. a picture on the even page before a chapter.
\startsetups [chapter:before]
\doifoddpageelse
{}
{\pushbackground[page]
\setupbackgrounds[page][background=color,backgroundcolor=blue,]
\page[empty,right]
\popbackground}
\stopsetups
As you see the image is not in the right place and of course the
pagenumbering
is wrong.
Use \startTEXpage[pagestate=start] to increase the page number with TEX
pages.
Thanks for this hint.
I want that one of these blue pages shows an image. Is this possible?
Yes but there are different ways for different requirements.
- Do you you have a picture before *every* chapter?
No, the additional image page shall appear only if the last chapter ends
on an odd page. Then I need the image page to push the new chapter to
the next odd page.
- Do you use full page images?
- Are the images cropped to fit the page dimension, stretched or
centered with margins?
For this usecase images are blown up and cropped to fit the page
dimension including the bleed.
\setuppagenumbering
[alternative=doublesided]
\setupexternalfigures
[location=default]
\definedataset [chapter]
\startsetups [chapter:before]

As you see the image is not in the right place and of course the pagenumbering
is wrong.
Use \startTEXpage[pagestate=start] to increase the page number with TEX
pages.
I want that one of these blue pages shows an image. Is this possible?
Yes but there are different ways for different requirements.
- Do you you have a picture before *every* chapter?
- Do you use full page images?
- Are the images cropped to fit the page dimension, stretched or
centered with margins?
- ...

[NTG-context] Let chapter start on odd page and make the even page before show an image
Dear all,
with your help I can colorize the empty even page right before a chapter starts
on the odd page. The mwe below shows it.
Now I would like to redefine the contents of the left page on the fly in the
text
so that I could place images on this page.
I thought that I could get a simple solution by inserting a TEXpage as even
page, but this does not work for several reasons. First a TEXpage is not counted
correctly like a normal page. And secondly I found now way to put it on the
even page.
So what I really want to achieve is a way to redefine this setups at some point
in the text to insert eg. a picture on the even page before a chapter.
\startsetups [chapter:before]
\doifoddpageelse
{}
{\pushbackground[page]
\setupbackgrounds[page][background=color,backgroundcolor=blue,]
\page[empty,right]
\popbackground}
\stopsetups
Here comes the not so mwe:
%% start mwe
\setuplayout [ location=doublesided ]
\setuppagenumbering[alternative=doublesided]
\definepagebreak [chapter] [footer,yes,header,footer,right]
\startsetups [chapter:before]
\doifoddpageelse
{}
{\pushbackground[page]
\setupbackgrounds[page][background=color,backgroundcolor=blue,]
\page[empty,right]
\popbackground}
\stopsetups
\setuphead
[chapter]
[
page=yes,
before=\directsetup{chapter:before},
]
\setupexternalfigure[location=default]
\starttext
\startchapter
[title={foo}]
\dorecurse{2}{\input tufte \par}
\stopchapter
\startchapter
[title={foo2}]
\dorecurse{6}{\input tufte \par}
\stopchapter
\startchapter
[title={bar}]
\input knuth
\startTEXpage
\externalfigure[cow.pdf][height=\paperheight,width=\paperwidth]

\stopchapter
\stoptext

Many thanks for your reply, Luigi.
This is a better approach for me.
Many thanks for help,

Hi Hans,
the following sample:
\starttext
\startTEXpage[offset=1em]
\doifinsetelse{i7}{i4, i5, i7}
{yes}{no}
\stopTEXpage
\stoptext
outputs "yes" with latest from 2020.05.18 16:50, but "no" with latest
from 2020.05.25 23:39.
I think this may be a bug, since the sample above would only get "yes"
with { i7}.
No spaces are allowed in these lists. Older versions of the command
removed the spaces before the entries but the current version is stricter.
we can use the old one, so only the raw variants then ignore the space;
best to be downward compatible, even if this was never the formal spec
(more a side effect)
it's only 20% slower and internally we we often use the raw one

Dear list,

Typeface is available at
https://github.com/dbenjaminmiller/garamond-libre/releases/latest.
Sorry, but I’m a bit thick now. Does anyone know why characters and OT
sups provide differently sized glyphs?
I think there might be a bug in the typeface, but I need to know first
what to report.
designers decisions ... i guess ... features are just tags and afaik
nothing really prescribes how to implement them (relative to each other)
