[NTG-context] Re: appendaction in "shipouts" "after" fails in the latest version
Sorry for re-asking this question by replying to myself; after many

Any hints are much appreciated.

[NTG-context] Downsampling images (again)
This is lying around for years, let’s try to get it finally working.
The code below works, but doesn’t do the right thing.
Since the original image doesn’t contain a resolution setting, gm
doesn’t do anything:
“gm convert: image does not contain resolution”
It would be more reliable to use “gm convert -resize”, but for that we
need to know the final pixel size.
How can a converter function access …
– the final (scaled) size of a placed image
– the original pixel size of an image
?
With that information it would be easy to calculate the target pixel size.
And then it would be nice to hook this function into
\setupexternalfigure[conversion=]
"""
\startluacode
local function downsampler(oldname, newname, resolution)
if not resolution or resolution == "" then
resolution = 72
end
local cmd = string.format(
[[gm convert -resample %ix%i "%s" "%s"]],
resolution, resolution, oldname, newname)
logs.report("downsample", cmd)
os.execute(cmd)
end
-- Set the PDF and default JPEG converters to the above function.
figures.converters.jpg.pdf = downsampler
figures.converters.jpg.default = downsampler
\stopluacode
\setupexternalfigure[
%conversion=downsampler,% not used
resolution=10,
]
\starttext

Since you’ve already got the chapter content split into separate \input files
...
At the Unix level, use the following script to run Context 180 times specifying
a different output file each time:
#! /bin/bash
for i in {1..180}
do
context \
--arguments="ChapNo=$i" test.tex \
--result="chapter_$i.pdf”
done
And at the Context level, test.tex is simply:
\starttext
\input chapter\env{ChapNo}
\stoptext

Joel,
others have suggested mutool and pdftk, which could be half the solution
for you. (I use pdftk for things like this, but I assume mutool is just as
good. Either are far less tedious than printing to file.)
If the information of the chapter boundaries is available in the log file,
a judicious use of grep and a few lines of shell script code might do the
trick. Alternatively, you might be able to use a tool like pdfgrep to find
the page numbers from the PDF file, and then use a few lines of shell code.
If you are a Linux or Mac user, this should be "easy enough". I don't do
windows, but now that there is (as I understand it) a bash shell available,
you might also be able to use grep and/or pdfgrep there as well.
If the log file isn't currently sufficiently helpful, could you add
something to your "start a new chapter" command to write a comment into the
log file giving you exactly the information you need?

Hi Joel,
I tried to recreate a document with chapters that contain a different
number of pages each:
\setuppagenumbering[alternative=doublesided]
\setuphead[chapter][reference=ch\the\numexpr\namedheadnumber{chapter}+1]
\starttext
\dorecurse{180}{%
\startchapter[title={Chapter \namedheadnumber{chapter}}]
\dorecurse{\randomnumber{10}{50}}
{\input zapf\par}
\stopchapter}
\stoptext
The key above is setting a reference for each chapter, so that they may
be retrieved later automatically.
Then you should have the pages for any chapter from its reference with
the following command:
context --pages=ch100 main-file.tex
But I must confess, I cannot get this working. I don’t know what I miss.
If you are on Unix, generating a bash loop would be similar to (once
your main PDF document has been generated):
for i in {1..180}; do mutool merge -o chapter-$i.pdf main-file\
"$(context --pages=ch$i main-file)"
But for that, you need to know first how "--pages=[reference]" may work.
Just in case it might help,
Pablo

You can use the pdf script file but it's slower than mutool or pdftk.
mtxrun --script pdf --split file.pdf

What is the meaning of \hss here? It seems to work just fine without it.

Thanks for this solution. It, however, seems to fail with any other angle than
315° (I tested 305, 325 and 314).

I guess, this one actually draws the text...

and this one calculates the faked width. Doesn't the sinus here calculate the
height of the rotated text?
Beside from using Metapost (since I currently do not understand it and would
only be able to copy paste your code), is there some kind of box construct
which artificially reduces the width of the inner content?
I would have expected something like \fakewidth[width=1cm,
align=flushright]{\rotate[rotation=-45, location=high]{A really long text, much
longer than 1cm}}.
If I see it right, such a construct would also solve the problem, while less
cleaner due to the fixed width.

[NTG-context] Inline equations and html export
Hello, Thanks Hans and everyone who has worked on it for the new upload! I have noticed a change which seems to break XML/html export for inline equations; although I don't know if the issue is with the new version or with how I'm using it. Minimal example: ``` \setupbackend[export=yes] \setupexport[alternative=html] \starttext $1 + 1 = 2$ \stoptext ``` When compiling with ConTeXt 2024.09.17 and opening either the `.html` or `.xhtml` file with Firefox or Chromium, the positions of the 2 and = sign are reversed, while the equation is correctly rendered when using ConTeXt 2024.08.16. The (I think) relevant part of the html code generated by ConTeXt 2024.09.17: ``` http://www.w3.org/1998/Math/MathML";>1+12= ``` Code generated by ConTeXt 2024.08.16: ``` http://www.w3.org/1998/Math/MathML ">1+1=2 ``` Am I doing something wrong here, or is html export for inline equations not currently supported?

[NTG-context] Table and rotation: push together 45 degree rotated cells
Hi,
I want to typeset a table where some of the column headings are really long,
while in the columns itself consists only of numbers.
Therefore, my idea was to rotate the column headings but not 90 degrees (I
found some solutions for that) but 45 degree.
It then would be beneficial to push together the rotated cells, so the text of
one cell actually starts above the previous cell.
Do you know, how to achieve that?
Here is a minimal example:
```
\startsetups[table:rotated]
\setupTABLE[frame=off]
\setupTABLE[row][first][bottomframe=on, style=bf, align={center, low}]
\setupTABLE[row][2][align=flushright]
\stopsetups
\starttext
\define\tablerotate{\dontleavehmode\rotate[rotation=-45, location=high]}
\bTABLE[setups=table:rotated]
\bTR \bTD \eTD \bTD \tablerotate{Water buffalo} \eTD \bTD
\tablerotate{Mexican redknee tarantula} \eTD \bTD \tablerotate{European turtle
dove} \eTD \eTR
\bTR \bTD Amount of legs \eTD \bTD \digits{4} \eTD \bTD \digits{8} \eTD
\bTD \digits{2} \eTD \eTR
\eTABLE
\stoptext
```
I would like to achieve that the text "Mexican redknee tarantula" is typeset
right and above of "Water buffalo" so that the single columns have a width that
is similar to the width of the single digit coming in the second row.
Another question in this context: Is is possible to specify a \setupTABLE
command that works for column 2-4 starting from row 2?
Something like \setupTABLE[row][2-][column][2,3,4][background=color,
backgroundcolor=red].
In this example this would cover all numbers but nothing else.

would be thankful to know if there's a way to change the spacing.
Please remove everything from your examples which isn't necessary to
show the problem, in your example you can get rid of
- the page layout,
- the font settings,
- the title page and
- all settings from \setupdescription and \setuphead unrelated to the
space between number/title and the text.
The value you're looking for is \spaceamount which can be used with the
distance-key to set the width of a space as separator.
For descriptions you have to set the value of the width to fit and use
the distance key to set a fixed
value for the space between the title and following text, to ensure the
space doesn't increase set
also the shrink and stretch values to 0.
begin example
\definedescription
[description]
[alternative=serried,
width=fit,
distance=\spaceamount,
stretch=0,
shrink=0]
\starttext
\startdescription [title={I'm not a fan of the}]
default spacing
\stopdescription
\stoptext
end example
For itemize you can use the fit keyword but be aware once you have more
than 9 entries you get
a bigger space between the number and content because the environment
set the width of all
entries to width of the widest number.
begin example
\starttext
\startitemize[n,fit][distance=\spaceamount]
\startitem
I'm not a fan of the default spacing
\stopitem
\stopitemize
\stoptext
end example
For section titles you just have to change the distance value.
begin example
\setuphead
[section]
[distance=\spaceamount]
\starttext
\startsection[title={I'm not a fan of the}]
default spacing
\stopsection
\stoptext
end example

[NTG-context] Re: Margins using 2UP imposition schema
Angel,
I used a lot of impositioning in the past.
If you want to have small white space at the outer edge, then do not use
width=fit. Control the inner whitespace with backspace=… Then calculate the
width of the textarea you want and set this value in width=... There is no need
to use cutspace in your approach.

[NTG-context] appendaction in "shipouts" "after" fails in the latest version
Hello, dear Hans.
I have a Lua module that doesn't work in the latest version 2024.08.16
16:30. After investigation,
I found that the errors first occurred in the appendaction. It could be appended
normally in the version 2024.04.01 08:59, but failed in the latest version. So,
I made a minimum runnable example for the appendaction problem,
mini-try.lmtx, as
```ConTeXt
\startluacode
Moduledata = Moduledata or {}
Moduledata.vtypeset = Moduledata.vtypeset or {}
function Moduledata.vtypeset.rotate_all1(head)
print(">>>>>> HERE IS ROTATE_ALL1")
return head, done
end
function Moduledata.vtypeset.rotate_all2(head)
print(">>>>>> HERE IS ROTATE_ALL2")
return head, done
end
nodes.tasks.appendaction("processors", "after",
"Moduledata.vtypeset.rotate_all1")
nodes.tasks.appendaction("shipouts", "after",
"Moduledata.vtypeset.rotate_all2") -- fails here
\stopluacode
\starttext

Compiled the mini-try.lmtx and got outputs in terminal:

Hello:
I'm composing an A5 booklet printed on an A4 paper using the 2UP

Any pointers, please?
Create a normal document without imposition in A5 and use afterwards the
arrange extra to produce your booklet.
You can get a short information block with an example when you write
context --extras=arrange
in the terminal.

[NTG-context] Unexpected behaviour of apa-bibliography
I do not know anything about the apa-standard, so I do not know if my rendering
follows the standard.
The first appearance of the author in the bibliography is marked with year-b
(1847b), the second with year-a (1847a). I expected the first to be marked with
year-a and the second with year-b.
Citing multiple references in one \cite[] only 2 out of 3 righttexts appear.
When using
\setupbtx[apa:cite][sorttype=none]
all 3 righttexts appear but the characters after the year disappear.
Is there a way to fix that behaviour?
Thank you. Have a nice weekend.

[NTG-context] Re: (ConTeXt LMTX 2024, monospace font) Why does monospaced text go out of the margin for me? is this supposed to happen?

The code linked above has 3 paragraphs. One in TImes New Roman, the other in
Aptos and the last in Aptos Mono.
The paragraph with \tt seems to go over my margin of .5 inches for the left and
right side of my doc., but the serif and sans serif text doesn't. I can't seem
to figure out why exactly this is.
Did I set up \setuplayout incorrectly? I wanted .5in margins but I kind of
'hacked' the way I got things. Is there a better way that I could have gotten
.5 inch margins and a.5in header/footer? I can't seem to understand why the
output is what it is. I would greatly appreciate any help!
Feel free to switch out the fonts if you'd like
You're trying to justify a text with a fixed width font which fails
because the often have a fixed width space. When you have a space a
fixed width TeX can stretch or shrink the space between the word to
align them with the right margin.
The best solution is to disable justification and use ragged text on the
right side. An alternative is to allow bigger spaces between words but
as you can see in the following example the gaps between words can be
quite large.
begin example
\showframe
\setupbodyfont[tt]
\starttext
\samplefile{zapf}
\blank
\start \setuptolerance[space]

When I try to use a combination (example =

I seem to be getting the same result when I try to load in a big paragraph.
However, there is an obvious difference between me entering (just) flushleft,
normal, flushright.
Have those options become obsolete? how am I supposed to know?
Whether there is a difference or not depends on your text, when you have
a wide
text block and short words TeX can produce good results without the need for
additional parameters but when you have a narrow text blocks (e.g. for
text in
columns) or long words you need additional settings.
The example below shows how different options can result in different
line breaks
but not all sample text produce the same effect, sometimes you get the
same result
with and without verytolerant etc.
Don't forget to enable expansion and protrusion before you use the
hanging and hz
options because they need these font features.

thanks for the detailed answer. Now it works!
I didn't realise until now that pdf is also messy. In my job I have
enough to do with the fact that some products never work as they should
("Mr Gates has won and now we have to use his products.’ - said our
former head of IT). I have nothing to do with IT, I am a scientist.
I am grateful for LaTeX, and of course I thank you, Hans, for ConTeXt!

Thank you for your time and patience.

Oh, I'm afraid that my “I hope for the future.” has now led to a

I would like to archive my documents as pdf/A-2a. As a reference to
the German Bundesarchiv, which recommends pdf/A-2a in the first
instance - and pdf/A-2u in the second.
I simply noticed that, as described in my initial email, the pdf/A-1a
and pdf/A-2a variants do not pass the validation test with verapdf.
Since there seems to be no way around this, I will probably have to
fall back on the second recommendation.
You cna try this:
\setupinteraction
[title=TITLE,
subtitle=SUBTITLE,
author=AUTHOR,
keyword={{KEYWORD1, KEYWORD2}, KEYWORD3}]
\setupbackend
[format={pdf/a-2a},
profile={default_cmyk.icc,default_rgb.icc,default_gray.icc}]
\setuptagging
[state=start]
\enabledirectives
[backend.usetags=mkiv]
\starttext
\chapter[chap:testing]{Testing}
\input knuth
\input tufte
\stoptext
This validates in the verapdf that i have installed (1.25.271).
So, you choose some standard (which we try to accomodate as good as
possible but who knows ... this one is a bloated one due to the icc
profiles). As you want tags we enable that (no need for it as long as
one is not finished with the document unless one wants to trace). We
also load the the old school mkiv mapping.
You can define your own mappings if needed. After looking into the
latest greatest volatile specifications Mikael and I decided that we
don't want to be waste too much time on it (at least not now as we hav
emore interestign thinsg to work on) and settled for what validates
and let users themselves decide. We mostly aim(ed) at making the
university enforced tools happy.
Structure in pdf is (to put it mildly) a mess, insufficient and never
will be (conceptually) okay, which is probably why it keeps being
adapted to what some applications can support or not. We don't want to
cripple what structure in ConTeXt we have. For the long time
accessibility tagging (there are other kinds of tagging being in use)
has been around for a quite vwhile now it has been the domain of
acrobat professional toolkit so in a broader context it is kind of
useless anyeay.
(One can wonder what organizations demanding it really have in mind,
given that older stuff doesn't validate and probably no one ever
checked how useful it is. But that's often the case with standrads
like this: some checkbox ticks so we're okay.)
So, the best we can do is to provide some flexibility, as usual in tex
tools,
Hans

to have kern=yes for it to enable? how can I test if extrakerns Is working?
when I just have kern=yes enable, and then enable extra, a pdf that has a
paragraph using both in code looks the same. locl is something I'm completely
unsure about.
1. Many features above are part of the default set.
2. When you don't know what the effect of an opentype feature is (look
at https://www.preusstype.com/techdata/features.php for a few examples)
don't enable it because you can get an unexpected output in your
document. It is also important to know what your font makes with the
feature because like I previously mentioned Times New Roman uses dlig to
produce standard ligatures which isn't what you expect here.

Oh, I'm afraid that my “I hope for the future.” has now led to a
misunderstanding.
I would like to archive my documents as pdf/A-2a. As a reference to the
German Bundesarchiv, which recommends pdf/A-2a in the first instance -
and pdf/A-2u in the second.
I simply noticed that, as described in my initial email, the pdf/A-1a
and pdf/A-2a variants do not pass the validation test with verapdf.
Since there seems to be no way around this, I will probably have to fall
back on the second recommendation.
You cna try this:
\setupinteraction
[title=TITLE,
subtitle=SUBTITLE,
author=AUTHOR,
keyword={{KEYWORD1, KEYWORD2}, KEYWORD3}]
\setupbackend
[format={pdf/a-2a},
profile={default_cmyk.icc,default_rgb.icc,default_gray.icc}]
\setuptagging
[state=start]
\enabledirectives
[backend.usetags=mkiv]
\starttext
\chapter[chap:testing]{Testing}
\input knuth
\input tufte
\stoptext
This validates in the verapdf that i have installed (1.25.271).
So, you choose some standard (which we try to accomodate as good as
possible but who knows ... this one is a bloated one due to the icc
profiles). As you want tags we enable that (no need for it as long as
one is not finished with the document unless one wants to trace). We
also load the the old school mkiv mapping.
You can define your own mappings if needed. After looking into the
latest greatest volatile specifications Mikael and I decided that we
don't want to be waste too much time on it (at least not now as we hav
emore interestign thinsg to work on) and settled for what validates and
let users themselves decide. We mostly aim(ed) at making the university
enforced tools happy.
Structure in pdf is (to put it mildly) a mess, insufficient and never
will be (conceptually) okay, which is probably why it keeps being
adapted to what some applications can support or not. We don't want to
cripple what structure in ConTeXt we have. For the long time
accessibility tagging (there are other kinds of tagging being in use)
has been around for a quite vwhile now it has been the domain of acrobat
professional toolkit so in a broader context it is kind of useless anyeay.
(One can wonder what organizations demanding it really have in mind,
given that older stuff doesn't validate and probably no one ever checked
how useful it is. But that's often the case with standrads like this:
some checkbox ticks so we're okay.)
So, the best we can do is to provide some flexibility, as usual in tex
tools,

Thank you for your careful and patient explanation.
I'll check my code again.
Because it's still very simple,
and some situations haven't been taken into account.
In particular, the condition judgment to split the part of the box.
I run your code and already found a few example where it fails, e.g.
- when you have a very short text it is spread over the while line and
you get a line break at the end
- when you use it in the narrower environment you don't compensate the
left/right indentations
Regarding the part about referencing commands,
I inadvertently forgot to delete it.
I have a question about the command "\warichuparameter\c!XXX" :
Why can we use "\warichuparameter\c!XXX" instead of "\warichuparameter{XXX}" in
most cases,
but in some cases, it says that the command is not defined?
For example, \warichuparameter\c!pointstyle --> Control sequence expected
instead of undefined
I've used "\warichuparameter\c!XXX" before, but it causes the error
because there are some keys that are specifically named.
For the sake of stylistic consistency, I used "\warichuparameter{XXX}" for all
command.
Maybe it's because I didn't define it? Should I define the following in advance?
%%%
\def\c!pointstyle{pointstyle}
%%%
Yes, these constants are predefined to have language dependent keys in
the setup command, e.g.
\setupitemize[width=1cm]
is written as
\stelleaufzaehlungein[breite=1cm]
with the german interface.
To ensure you use the correct name for the key you use \c!width as
argument for the \xxxparameter command.
While you can use \def\c!...{...} to create a new constant the proper
method is to use \setinterfaceconstant.
You can run the following example to get a list with a predefined
constant. When you uncomment the first three lines you see the new entry
also appears in the list.
begin example
% \startinterface all
% \setinterfaceconstant {pointstyle} {pointstyle}
% \stopinterface
\setuplayout[tight]
\starttext
\startluacode
context.startcolumns({n=3})
for constant, _ in table.sortedpairs(interfaces.constants) do
context.mono(constant)
context.par()
end
context.stopcolumns()
\stopluacode
\stoptext
end example

With the \ssd the first number at the top of the second and subsequent pages is
one less than it should be. Without the \ssd then the numbers are as expected.
@Muyik: Are you able to use \pagenumber without using \ssd or similar to change
the size? That might be a work-around for you. There is also \userpagenumber.
You can't use page counters in running text without problems because
you're working against the way how TeX constructs pages.
The only reliable way are multipass solutions like the pagestate or
reference mechanism.

You have to differentiate between odd and even and right hand and left
hand pages.
When you want to check whether you have an right hand or left hand page
you can use the following method.
To get the correct result ensure you start a paragraph before you set
the flag with \signalrightpage.
begin example
%\setuppagenumbering[alternative=doublesided]
%\setuppagenumbering[alternative={singlesided,doublesided}]
\starttext
\dorecurse{20}
{\dontleavehmode\signalrightpage\doifelserightpage{\bold{Right

\samplefile{lorem}}
\stoptext
end example
To have a check which works for odd and even pages you have to use the
pagestate mechanism.
Even in this case it is important to start a paragraph before save the
current state, afterwards
you can check the stored pagenumber.
begin example
\definepagestate[warichu]
\starttext
\dorecurse{20}
{\dontleavehmode\autosetpagestate{warichu}%
\ifodd0\autopagestaterealpage{warichu}%

[NTG-context] how do I get the correct page numbers and do the calculations with it?
Thank to all who answered my questions before.
As the title suggests, how do I get the correct page numbers?
For example, in the example below,
the first line on the 2nd page, but the page number showed is 1,
In the meantime, I tried using \definepagestate,
but it didn't seem to work either.
What I can think of is to use citations to get the correct page number.
But it seems that what is obtained is not a pure number,
and it cannot do the calculations.
so ,how do I get the correct page numbers and do the calculations with it?
thanks.

indeed, because old school \not was a symbols that got overlayed.
we could of course make some clever not but i hav eto discuss that

My main reason for the question was to get clarification about the

Using the proper commands (e.g. \notin) was always the better choice
because they produce better output than \not does.

indeed, because old school \not was a symbols that got overlayed.
we could of course make some clever not but i hav eto discuss that with

[NTG-context] Re: ConTeXt beginner, What should I enable within font features? And how do I see all the options possible?
Felix schrieb am 05.09.2024 um 22:58:
https://pastebin.com/245uwYj4
I have this setup for my fonts, called myfonts.
I assume that `\definefontfeature [default] [default]
[trep=yes,dlig=yes,itlc=yes]` will affect every single font that goes into my
preamble (Forgive me if I seem incompetent, I am a beginner at ConTeXt)
It is applied to all fonts which use the "default" feature set and which
enabled after you made the changes.
In the following example only pagella uses the "trep" feature because
modern was loaded before the settings was added to the default feature set.
begin example
\starttext
\setupbodyfont[modern]
a'b
\definefontfeature [default] [default] [trep=yes]
\setupbodyfont[pagella]
a'b
\stoptext
end example
To be on the save side create custom feature set where you add
additional settings and apply these to your fonts.
begin example
\definefontfeature [MyFeatures] [default] [trep=yes]
\definefontfamily [OldTimes] [rm] [Times New Roman]
\definefontfamily [NewTimes] [rm] [Times New Roman] [features=MyFeatures]
\starttext
\setupbodyfont[OldTimes]
a'b
\setupbodyfont[NewTimes]
a'b
\stoptext
end example
I have dlig and trep on so that works with single quotations like don't have a
directional quote, and so that I get the Times New Roman ligatures via dlig and
not just liga. itlc is enabled since I read some documentation and they
sometimes mention enabling it
It shouldn't be necessary to add "itlc" anymore to get italic correction
for \em etc.
is there some stuff like the extrafeatures option or anything that you would
recommend i enable? might there be options for extrakerns that would be seen as
something that one should enable?
also, how can I see all the options available? dlig is something I discovered
by accident that was not in the options list in the documentation.
Unless you know the effect of a feature you shouldn't add or enable it.
You even have to know what is supported by the fonts in your document
which can differ between certain versions of a font, take Times New
Roman which is included with Windows as an example.
1. For a long time ligatures weren't supported by the font at all and
the first mention of the support it is from 2022.
2. The font uses the "dlig" feature to enable the f ligatures even
though the normal tag for it is "liga". My guess why they made this
decision is backwards compatibility with existing document to avoid them
from using these ligatures.
3. You shouldn't enable "dlig" by default for all fonts because the
results of the feature can vastly for the fonts which provide it, take
the following two fonts as example.
begin example
\definefontfeature [discretionary-ligatures] [dlig=yes]
\starttext
\startbuffer[pagella]
\starttabulate[|||]
\NC \type{} \EQ \NC\NR
\NC \type{--} \EQ -- \NC\NR
\NC \type{!`} \EQ !` \NC\NR

\NC \type{?`} \EQ ?` \NC\NR
\NC \type{?‘} \EQ ?‘ \NC\NR
\NC \type{,,} \EQ ,, \NC\NR
\NC \type{‘‘} \EQ ‘‘ \NC\NR
\NC \type{’’} \EQ ’’ \NC\NR
\NC \type{---} \EQ --- \NC\NR
\stoptabulate
\stopbuffer
\setupbodyfont[pagella]
\start \nohyphencollapsing
\getbuffer[pagella]
\stop
\start \nohyphencollapsing \feature[+][discretionary-ligatures]
\getbuffer[pagella]
\stop
\startbuffer[dejavuserif]
\starttabulate[|||]
\NC \type{ſt} \EQ ſt \NC\NR
\NC \type{st} \EQ st \NC\NR
\stoptabulate
\stopbuffer
\setupbodyfont[dejavu]
\start
\getbuffer[dejavuserif]
\stop
\start \feature[+][discretionary-ligatures]
\getbuffer[dejavuserif]
\stop
\stoptext
end example
The only additional features which can be added without problems are
"expansion" and "protrusion" because until you enable them with
\setupalign nothing changes in your document.

[NTG-context] Re: Is there an alternative to \reference[]{} that won't interfere with the document design?
Jürgen Hanneder via ntg-context schrieb am 31.08.2024 um 17:27:
I recently learned not to leave a space before and after \reference ,
but have not seen
further complex problems as you describe so far. Can you give more
specific examples for these,
I have to check, because I am also finalising a book at the moment.
References need an anchor to know on which page they end up because a
page is finished you don't know the answer.
The following example sets three references, one and three marks the
start of each paragraph but where should two end up?
begin example
\usemodule[visual]
\setuppapersize[A6,landscape]
\setupwhitespace[line]
\starttext
\showmakeup[hbox]
\pagereference[one]\fakelines{10}{10}
\pagereference[two]
\pagereference[three]\fakelines{10}{10}
\page
\showmakeup[reset]
\starttabulate
\NC one \NC \at[one] \NC\NR
\NC two \NC \at[two] \NC\NR
\NC three \NC \at[three] \NC\NR
\stoptabulate
\stoptext
end example
When you process the example you get page 1 as output, but why is this
the case. Take a look the the tracing information and you can see a "H"
at the left bottom on page 1 which is missing on page 2, this is where
ConTeXt places reference two. You get this "H" mark because
\pagereference starts a new paragraph to ensure the is a anchorpoint but
as a side effect you can end up with unwanted empty lines in your
document, to test this change the argument of the first \fakelines from
10 to 12 and now the stray "H" appears at the top left on the second
page but in addition you get 2 empty lines at the top (1 for the
reference and another 1 for the parskip).

[NTG-context] Re: Inserting text between end notes
Thank you for that, Bruce.
While it is still a hack, as you note, it is less fraught since one does
not have to keep track of the last end note in each chapter.
I would still like to see a real ability to add text to the note collection.

Hello all,
I am trying to implement some style-guide-defined (Chicago 17, and now, 18)
requirements to the end notes in a book. The need is to insert non-end-note
text into the list of end notes. But end notes are not a list (as far as I can
see) and \writetolist and such are no help.
The text to be inserted is of two types. The first is the name of the chapter
from which the following notes were generated. It would be nice to
automatically generate these.
The second type is pseudo-end-notes crediting the book and chapter epigraphs,
which should appear as unnumbered end notes (at the start of the note section
and the start of each chapter's notes). Ideally these would be generated in the
same way as regular end notes but will not increment the note numbers (and
should not, at least in my use case, require cross-referencing or bookmarking).
I can hack the first requirement with:
\define[1]\EndNoteChapter{\testpage[3]
\blank
\midaligned{\tfa{Chapter #1}}
\blank}
in the environment and
\EndNoteChapter{6 How I Saved the World}
at the end of the last end note in the preceding chapter, but this is obviously
prone to mistakes. I would rather integrate the handling into the chapter
heading environment.
I suppose that this hack might be extended to handle the epigraph notes as
well, but it is just a hack.
Has anyone successfully dealt with this before? If not, is there the
possibility of adding similar functionality to \writetolist and such for end
note structures?
Here’s a bit of a hack for the chapter splitting and might also enable the
epigraphs for you as well (not quite sure what these should look like from your
description.)

\setupnote[mynote][location=text]
\setupnotation[mynote][]

[NTG-context] Combining styles (especially bold and italic)
Hi,
I have the situation that I want to typeset a special formatted name within a
section heading.
The name contains an italic part while the heading is bold, but both styles are
defined at another place.
Is there a way to tell ConTeXt to combine them, so that it is bold _and_ italic?
Here is a minimal example:
```
\define\somename{HX\style[italic]{print}\autoinsertnextspace}
\setuphead[section, subject][style={\bfc}]
\starttext
\startsection[title=The \somename name]
\somename is a strange written name.
\stopsection
\stoptext
```
In the normal text, HXprint is written correctly, in the section heading
"print" is italic but not bold.

[NTG-context] Placement of floats with an "anchor"
Hi,
in my document, I recently left a TODO note that said:
"This floating graphic needs to be on the same page than this formula at the
end."
My floating graphic currently uses:
\startplacefigure[title={bla}, location=top, reference=fig:bla]
...
\stopplacefigure
The graphic should be at the top of the page where the formulas are typeset at
the end.
Normally, I would do that manually, when all other text is finished.
Can I somehow automate this in ConTeXt? So defining a (non visible) "anchor" at
a random place within the normal text and then tell ConTeXt to place the float
at the same page (if possible)?
Here is a minimal example to play around (the float is placed on page 1, while
the "anchor" is on page 2).
```
\starttext
\input{knuth}
\input{knuth}
\input{knuth}
% anchorto is made up to demonstrate the problem
\startplacefigure[title={A figure explaining the formula.}, location=top,
reference=some, anchorto={eq:important}]
\startalign[center]
\style[sans]{This is a figure that explains the formula.}
\stopalign
\stopplacefigure
It is explained with these equations (see also figure \in[some]):
\startformula[reference=eq:important]
\startalign
\NC a \NC = b \NR
\NC a \NC = b \NR
\NC a \NC = b \NR
\NC a \NC = b \NR
\NC a \NC = b \NR
\NC a \NC = b \NR
\NC a \NC = b \NR
\NC a \NC = b \NR
\NC a \NC = b \NR

Though, I am having trouble with the table that goes over the big sized text
that would be my name. It has an email, a phone number, and an address but
they are all aligned very weirdly. I want them to be centered. Though, the
phone number has some sort of problem with alignment, and I don;t know fi the
other ones are causing it or are also aligned wrong.
I also wanted to make this code:
\startxcell[topframe=on,bottomframe=on,align=flushright]
Ability to communicate strongly and effectively, being a reliable team
member, supporting a team whenever needed, and the desire to help everyone
\stopxcell
has it so that it doesn't take up so much horizontal space (Ideally it is
taking up 1/3 of the width I am allowing for since there are three rows in
total) , but when I add width={some value} into the square brackets, it will
add a blank line after all the text, and this is not what I want.
You have to add "option=fixed" to the cell with the width setting.

I am trying to make a resume in ConTeXt (to see how well my skills have gotten,
I am still quite a beginner) and Iw as able to produce what is in Pastebin.
Your next lesson is to learn how to create a minimal example which
contains only the necessary information needed to show the problem.
Though, I am having trouble with the table that goes over the big sized text
that would be my name. It has an email, a phone number, and an address but
they are all aligned very weirdly. I want them to be centered. Though, the
phone number has some sort of problem with alignment, and I don;t know fi the
other ones are causing it or are also aligned wrong.
I also wanted to make this code:
\startxcell[topframe=on,bottomframe=on,align=flushright]
Ability to communicate strongly and effectively, being a reliable team
member, supporting a team whenever needed, and the desire to help everyone
\stopxcell
has it so that it doesn't take up so much horizontal space (Ideally it is
taking up 1/3 of the width I am allowing for since there are three rows in
total) , but when I add width={some value} into the square brackets, it will
add a blank line after all the text, and this is not what I want.
is there a way to fix what I am experiencing? I would also not mind if I could
be told how to improve my code, whether it be by adding startxrowgroup,
startxcellgroup, or head and footer sections., or other options. Thank you for
reading.
Your problem the usage of "option=stretch" to add filler space in the
table cells.
To calculate the space which is added in each cell context takes the
widest text in each column
to calculate the current width of the table and when table is narrower
then the page it distributes
the reaming spaces equally to all rows. This results in a different
width for each row but another
problem in your case is that context takes the long text in the first
row (even though it spans
three column) as value to compute the reaming space in the table.
The fix for your case is to set a fixed width for all three column which
ensures the text
in the second column is centered. You can also simplify your setup by
moving all settings
at the start of the table and the only local change is needed for the
merged cells.
begin example
\starttext
% width=.33tw
\startxtable[frame=off,topframe=on,bottomframe=on,width=.33tw,align=middle]
\startxrow
\startxcell[nx=3]

[NTG-context] Problem with end note processing
Hello all,
I am working through some issues with end notes, and came across a what
appears to be a bug as demonstrated in the following MWE.
ConTeXt ver: 2024.08.16 15:49 LMTX fmt: 2024.8.16 int: english/english
\setupnote [endnote][location=none]
\setupnotation [endnote][]
\starttext
text\endnote[-]{end note}
text\endnote{end note}
%text\endnote[-]{end note}
\placenotes[end note]
\stoptext
When run as shown, both end notes get indices, but the first should not.
When the commented line is enabled, none of the three end notes gets an
index, but the second should. It seems that the last end note determines
the display for all end notes.
I have other questions about end notes that I will submit separately.

1. You forgot to provide a minimal example to reproduce the problem.

This is a much better specified question.
It would ideally require some work both on the Asymptote side, as well
as some work on the ConTeXt side.
Asymptote is in fact written in C++, so it might be a lot closer to
your particular expertise.
I would say that what's most needed is someone with a great passion to
get this complete, and some clear communication pathway between the
two projects.
Asymptote is very LaTeX-centric and should ideally be ConTeXt-ilized
to simplify some operations. I would start by playing with a super
simple minimum example written in plain asymptote. Figure out how to
compile Asymptote on your computer and try to process the asy file
into a ConTeXt file. This conversion then needs to be tweaked in order
to produce two different results:
- A standalone file that could be processed directly by ConTeXt.
- A minimalistic file that could be included from another ConTeXt
source to generate the final document.
Check the file that you get right now, figure out what goes wrong,
what could be improved ...
If you have a simple file that no longer needs asymptote processing,
you can check on the ConTeXt list what could still be improved, and
then you can go and start fiddling with Asymptote source code (with
help of Asy developers) until the files get progressively better.
Iterate between the Asymptote and ConTeXt developers until the results
are fully satisfactory.
It has been a while since I touched any asymptote, but I suspect that
what you want to achieve is something like
\starttext
\startasymptote
some graphics
\stopasymptote
\placefigure[label]{really nice 3D model}{%
\startasymptote
another 3D graphics
\stopasymptote}
\stoptext
where ConTeXt would process this file, prepare some input to
asymptote, and then asymptote would have to be called just once to
generate all the required graphics at once, and ConTeXt would
eventually include them, properly scaled etc.
Start with graphics, continue with simple text labels ... progress
towards proper interactive 3D models ...

ConTeXt does support native syntax highlighting. You can try to create
some new grammars to extend language coverage (Hans only made sure
that TeX, lua, metapost etc. work correctly). Or you can try to start
brainstorming whether some existing OpenSource grammars could be
integrated to do syntax highlighting using Lua.
Vi was a shortcut to get the syntax highlighting done in some way at all.
In either case start a separate thread covering exactly that one topic.

Hi,
I played around with different fonts, especially Bitstream XCharter and
Overpass (http://overpassfont.org/) and wanted to combine them.
However, I see some issues regarding ligatures, kerning and obliques/italics.
Here is a minimal example:
```
\definefontfeature[default][mode=node, kern=yes, liga=yes]
% more features
% [mode=node, kern=yes, liga=yes, tlig=yes, itlg=yes, ccmp=yes, language=dflt,
protrusion=quality, expansion=quality]
There is no need to set default features like ligatures and kerning, the
better alternative here is to use
\definefontfeature [default] [default] [protrusion=quality,...]
which adds additional settings to the default set.
\definefontfamily [myfont][roman][xcharter]
\definefontfamily [myfont][sansserif][overpass][rscale=0.93]
\definefontfamily [myfont][teletype][overpass][rscale=0.93]
\definefontfamily [myfont][mono][overpassmono][rscale=0.93]
\definetypeface [myfont][mathematics][math] [xcharter]
\setupbodyfont[myfont, 11pt]
\startTEXpage
\showfontkerns
Vitae, Vase, LT, VA, Y., Effizient, abcdel™, \italic{effi
abcdel™}, \slanted{effi abcdel™}\\
\style[sans]{Vitae, Vase, LT, VA, Y., Effizient, abcdel™, \italic{effi
abcdel™}, \slanted{effi abcdel™}}\\
\style[mono]{Vitae, Vase, LT, VA, Y., Effizient, abcdel™, \italic{effi
abcdel™}, \slanted{effi abcdel™}}\\
\showbodyfont[myfont]
\stopTEXpage
```
It produces the PDF in the attachment. I'm struggling with several things:
- xcharter seems to have no kerning applied. It is listed as font feature,
though. Is it correct to have no kerning at all for that font?
The font has kerning information but none for characters in the ASCII range.
Good to know. Especially for the "Va" in "Vase", I expected kerning (it looks
not equally spaced currently).
- xcharter also have no ligatures (at least it doesn't look like that). That is
listed as font feature, too, although only for italic and slanted. According to
https://tug.org/FontCatalogue/xcharter/ there are ligatures in the font.
There are ligatures for ff[il].
They are defined in the font, but they are not used in the PDF output, aren't they? For example in the "ffi"
in "Effizient" the "f" is not connected with the "i", while the ligature glyph has a
connection there.
You have to change the value of the script tag because the don't set
them for the dflt script.
\definefontfeature[default][default][script=latn]
\definefontfamily[myfont][rm][xcharter]
\setupbodyfont[myfont]
\showmakeup[glyph]
\starttext
ff fi fl ffi ffl fb fh fk
\feature[-][ligatures]
ff fi fl ffi ffl fb fh fk
\stoptext
I attached a screenshot for comparison. The ligature was generated with
"\ShowCompleteFont{name:xcharter*default}{11pt}{1}" (with the fnt-10 module).
It is, however, noticeable that the whole xcharter font is thicker in the
output of \ShowCompleteFont. Is this part of the reason?
When you load a font by name use one which is listed in the table you
get with "mtxrun --script fonts --list --all --pattern=xcharter*". In
this case the table is
identifier familyname fontname
filename subfont instances
xcharterbold xcharter xcharterbold XCharter-Bold.otf

xcharterroman xcharter xcharterroman XCharter-Roman.otf
xcharterslanted xcharter xcharterslanted
XCharter-Slanted.otf
and as you can see there is no entry "xcharter". In your case context
loaded the bold version of the font but when you use "xcharterroman" as
name the document shows the normal upright version.
- Overpass has a glyph for the ae ligature. Is it normal that it is not used as
a ligature for ae?
This seems to be a stupid decision to replace ae by default with a
ligature, maybe dependent on the language but not for all of them.
Ok, I've seen it here as (somewhat) common ligature:
https://en.wikipedia.org/wiki/Ligature_(writing)#Computer_typesetting
But there is also mentioned that TeX just has ff, fi
[NTG-context] BUG REPORT: Italic Correction in ConTeXt LMTX
Hello,
I started using ConTeXt LMTX 2 days ago and after some initial testing I
noticed an unexpected behavior regarding italic correction.
In short, I cannot seem to produce italic correction like I could in plain TeX
or even LaTeX.
I've asked the question on TeX StackExchange and another user confirmed the
suspicion in his answer. I would suggest you take a look at it because the
formatting of the question and the answer is prettier than in this plain text
email. Furthermore, a person who provided the answer already did some research.
See the question here:
https://tex.stackexchange.com/questions/724568/how-to-invoke-italic-correction-in-context-lmtx
Here is what I observed:
Compare the kerning produced in between 'r' and 'p' in the word "airport" when
italic correction is applied in plain TeX (compiled with `pdftex`) and in
ConTeXt LMTX (compiled with `luametatex`). Here are the minimal working
examples.
Plain TeX
```
airport (regular font)
{\it air\/}port (italic correction applied)
{\it air}port (no italic correction applied)
\bye
```
ConTeXt LMTX
```
\starttext
airport (regular font)
{\it air\/}port (italic correction applied)
{\it air}port (no italic correction applied)
\stoptext
```
Please confirm if this, in fact, is the issue/bug or if I am not approaching
this correctly. I am brand new to ConTeXt, so it could be me. Thank you in
advance!
Vladimir

[NTG-context] index entry with sorting and processor
Hi again,
the page number of register entries from a glossary should have a
different color:
\defineprocessor[glossar][color=green]
\define[1]\GlIndex{\index[glossar->]{#1}}
This works, but I’d like to apply a macro to the text, and then I need
to set the sort order:
\define[1]\GlIndex{\index[glossar->#1]{\Word{#1}}}
This also works, but I get separate index entries from
\index{Something}
and
\GlIndex{something}
Glossary entries may be lowercase, but in the index I’d like to
normalize to uppercase initials. (The index command is part of a lemma
setup.)
How can I combine the entries?
I also tried \setregisterentry but didn’t find out how to use a
processor for the page number. In the wiki, the (generally working)
processor option is undocumented, so if there’s another option, it’s
also missing.
In the source, I found processors for entry & page, but not how to
address the latter.
MWE:
"""
\defineprocessor[glossar][color=green]
\define[1]\GlIndex{\index[glossar->#1]{\Word{#1}}}
\starttext

[NTG-context] Is there a short-cut to adding sub-categories for index entries?
I have a document with thousands of index entries. Here’s a samplecode:
\starttext
Some people livedin \index{cliff-dwelling}cliff-dwellings, while others lived
in\index{lean-to}lean-tos.
\placeindex
\stoptext
This produces anindex like this:
c
cliff-dwelling 1
l
lean-to 1
I’d like to createan index with much more sub-categories to find the same
entries, forinstance, a category of “dwellings”:
c
cliff-dwelling 1
d
dwellings
cliff-dwelling 1
lean-to 1
l
lean-to 1
As I’m aware, theway to code this is as follows:
\starttext
Some people
livedin\index{cliff-dwelling}\index{dwellings+cliff-dwelling}cliff-dwellings,while
others lived in\index{lean-to}\index{dwellings+lean-to}lean-tos.
\placeindex
\stoptext
I’m wondering ifthere is a short-cut means to set this up, such that if I can
tellthe document that any time it sees “cliff-dwellings” in an index,it will
also add its page numbers to under “dwellings+cliff-dwelling”? In other words,
is there an easierway to add these categories, then to go through the entire
documentand mark them? I already have a list of all the words.
For instance, in my above code, I must find every \index{cliff-dwelling} entry
and add a \index{dwellings+cliff-dwelling} next to it...which would take
hundreds of hours if I did that for every word. Is there a quicker way to tell
it always also add it under "dwellings" too?

The unknownpicture was there to hint that you did not give an example showing the problem. The compact= was an initial guess by an anonymous participant at the meeting.

The file compiles and just has a grey empty box saying "name: unknownpicture". If I replace xmap1.pdf with a JPG named xmap1.jpg and don't change the document otherwise, my document compiles just fine. The problem is I need high quality files, not a blurry JPG. --Joel On Sunday, August 18, 2024 at 09:14:37 AM MDT, Mikael Sundqvist wrote: Hi, >From the meeting: What happens if you do \externalfigure [unknownpicture] [compact=] ?

[NTG-context] Why are some external PDF figures leading to a stack overflow error?
I am making a book that includes a series of maps which I created in LibreOffice Draw, but exported as a lossless PDF. After recently making some improvements to the map files, but not the ConTeXt documents, I was surprised my document wouldn't compile anymore...I couldn't find any code errors and even reverted to older code from the day before that compiled fine yesterday. It seemed the PDFs themselves were making the errors, but the errors were inconsistent..

[NTG-context] Bug Regarding IIalic Correction in ConTeXt LMTX
Hello,
I started using ConTeXt LMTX 2 days ago and after some initial testing I
noticed an unexpected behavior regarding italic correction.
In short, I cannot seem to produce italic correction like I could in plain TeX
or even LaTeX.
I've asked the question on TeX StackExchange and another user confirmed the
suspicion in his answer. I would suggest you take a look at it because the
formatting of the question and the answer is prettier than in this plain text
email. Furthermore, a person who provided the answer already did some research.
See the question here:
https://tex.stackexchange.com/questions/724568/how-to-invoke-italic-correction-in-context-lmtx
Here is what I observed:
Compare the kerning produced in between 'r' and 'p' in the word "airport" when
italic correction is applied in plain TeX (compiled with `pdftex`) and in
ConTeXt LMTX (compiled with `luametatex`). Here are the minimal working
examples.
Plain TeX
```
airport (regular font)
{\it air\/}port (italic correction applied)
{\it air}port (no italic correction applied)
\bye
```
ConTeXt LMTX
```
\starttext
airport (regular font)
{\it air\/}port (italic correction applied)
{\it air}port (no italic correction applied)
\stoptext
```
Please confirm if this, in fact, is the issue/bug or if I am not approaching
this correctly. I am brand new to ConTeXt, so it could be me. Thank you in
advance!
Vladimir

If I remove "\startplacefigure and \stopplacefigure”, then there is no error,
but the figure is not centered.
Please tell me how to fix it.
Thank you for reading.

[NTG-context] Breakable tcolorbox in ConTeXt
Hi,
I am trying to reproduce the behaviour of the tcolorbox LaTeX package, more
specifically breakable boxes (as illustrated here:
https://tex.stackexchange.com/a/676607/123770). It works nicely out of the
box (pun intended) using `\definetextbackground` and drawing the frame with
MetaPost, using counters to keep track of whether the current text is at
the top, middle, or bottom of the box. However, I'm having issues when one
box ends and another starts on the same page (see more details below). From
what I understand, the issue is that counters seem to be updated on a
page-wide basis, so each MPgraphic ‘sees’ the values of counters at the end
of the current page, which may not be right if another box modifies them.
Would anyone know how to resolve this?
Based on two answer on TeX StackExchange (
https://tex.stackexchange.com/a/486124/123770 ,
https://tex.stackexchange.com/questions/377234/context-frame-problems/377261#377261),
the following code works well if there is no more than one box per page:
```
\definecounter[pageNumberTop]
\definecounter[pageNumberBottom]
\startuseMPgraphic{mp:axiomframe}
begingroup;
for i=1 upto nofmultipars :

fill p withcolor boxfillcolor ;
% if the current page is the first one covered by the box...
if (\pagenumber == \rawcountervalue[pageNumberTop]) :
% ... if it is also the last one, the box fits entirely on the
page; we thus draw the full frame

withpen pencircle scaled 2pt
withcolor boxlinecolor ;
% ... otherwise, don't draw the bottom line

% if the current page is the last one covered by the box, draw the
left, bottom, and right lines
elseif \pagenumber == \rawcountervalue[pageNumberBottom] :

after={\setcounter[pageNumberBottom][\pagenumber]}]
\definestartstop
[ColoredBox]
[before={\blank[2em]\starttheoremFrame},
after={\stoptheoremFrame\blank[2em]}]
```
For instance,
```
\startColoredBox

\input knuth
\input knuth
\input knuth
\input knuth
\input knuth
\input knuth
\input knuth
\input knuth
\input knuth
\input knuth
\stopColoredBox
```
correctly gives a box split over multiple pages, with the top part of the
frame only drawn on the first page and the bottom part only drawn on the
last one.
It also works correctly when adding `\page` between boxes:
```
\starttext
\startColoredBox
\input knuth
\input knuth
\input knuth
\input knuth
\input knuth
\input knuth
\input knuth
\input knuth
\input knuth

\input knuth
\input knuth
\input knuth
\input knuth
\input knuth

However, the following gives an incorrect output:
```

Is there a reason why do the alignment change within a local group?
The problem is that is messing with footnotes, causing things like URLS
