[NTG-context] index sort order (de)

[Henning Hraban Ramm]

Hi,
I checked the German index sorting rules, and as far as I can tell, all 
of them are somewhat wrong.


– de, default, or no setting (just mainlanguage de)
– Duden
- DIN 5007-1(:2005)
- DIN 5007-2(:1996)
- de-AT

IMO, "Duden" is obsolete, should be the same as default; it makes no 
sense to have a default setting that doesn’t adhere to the official 
rules. If Û#m not mistaken it’s also the same as DIN 5007-1; maybe there 
was a difference before 2005. (DIN 5007-2 and de-AT have their uses.)


The order of umlauts etc. should be ok.

[ß]
In tex/context/base/mkiv/sort-lan.lua, ß is replaced by s, while it 
should be sorted like ss in default and both DIN versions. (de-AT sorts 
ss after ß.)


[upper-/lowercase]
While casing is not mentioned in Wikipedia 
(https://de.wikipedia.org/wiki/Alphabetische_Sortierung), Duden „Satz 
und Korrektur“ says:


Uppercase characters get sorted the same as lowercase (i.e. mixed), but 
if both appear, lowercase comes first.


ATM all German settings sort lowercase behind uppercase.



Generally, default method seems to be not "default" but "before". Does 
this make sense?


If we look at the method presets, there’s none for {zm,pm,zc,zm,uc} 
(upper like lower, ignore diacritics – basic default for German).

Interesting task. Perhaps via multitone colors?
https://wiki.contextgarden.net/Spot_Colors

Otherwise you can use \definetransparency and \starttransparent around 
\color (or \startcolor).

(Same blurb as always:)

[Howto]
* No special software installation required; most modern browsers should 
work (WebRTC required).

* Open the URL above, accept the privacy statement,
* enter your name,
* click "join" (or "start" if you’re the first),
* click "with microphone", allow your browser to access it, check the audio.
* Your microphone is muted if you join. Activate microphone and/or 
camera with the buttons at the bottom.

* Minimize the default presentation with the "screen" button, bottom right.

* If you’d like to share your screen or upload a file, you can make 
yourself the presenter: Click on your user name, change the setting, 
then you’ll see the "screen sharing" button beside the camera button; 
also there’s now "manage presentations" behind the "plus" button.
Beware there is only one presenter at a time, so don’t kill someone 
else’s presentation.


[Technical hints]
* Sound is usually better if you use a headset (less noise for everyone).
* Connection problems are mostly due to low bandwidth or high latency on 
your side, e.g. with mobile connections.

* Sometimes leaving and re-entering helps.
* If audio/video doesn’t work for you, you can still use the text chat.
* Screen sharing needs a lot of bandwidth.
* BigBlueButton documentation applies: 
https://bigbluebutton.org/teachers/tutorials/


[Netiquette]
* Please use a name that we recognize from here. Some feel uncomfortable 
with anonymous lurkers.

* Mute your microphone while you’re not talking.
* It’s nice to show your face at least when you join.
* If there are connection problems, stop camera sharing.
* The room is set to “everyone’s a moderator“, I trust you...

Am 01.05.24 um 09:44 schrieb Wolfgang Schuster:
but that should be sufficient, but to repeat Hraban's question: What 
would be the advantage of using the format module?


The module provides features like

     - alignment of the verse lines
     - numbering of the lines (which isn't supported by \startlines 
unless you add the normal linenumbering mechanism)
     - support for lines which don't fit on a single page where the 
consecutive lines are indented


but the module is outdated and relies on an old mkii style code base.

A big difference between the \startlines environment and the format 
module is that the first treats
each line in the input file as a separate line in the output while the 
format module requires begin/end

tags for each line which works better for xml input.


Thank you! Doesn’t sound like I should use it…

[NTG-context] Re: QR Code

[Henning Hraban Ramm]

Hi Ben,

I’m not sure if this is your issue, but the zint library’s API used to 
change with every version, so that ConTeXt supports only the “latest” 
few, and probably that’s still 2.10 to 2.12.


I still have 2.12 via MacPorts on MacOS 10.15, and it works.
Can you try an older zint version?

And just for information, MkIV used to call the zint binary, while LMTX 
uses the library to create the structures and converts them via MP into 
PDF objects (no additional files).

Catching up on an earlier thread by Ursula and Hraban,

I'm also experienceing problems with \usemodule[zint] while \usemodule[t-zint] 
works fine.

Running on macOS (ConTeXt  ver: 2024.04.01 08:59 LMTX  fmt: 2024.4.28).

The issue seems somewhat unrelated to ConTeXt on first glance (??) if this is 
helpful. My code stopped working after I updated the OS (to Sonoma) and my 
homebrew cellar (to zint 2.13.0) while keeping a ConTeXt version from 2022 
which compiled the barcodes perfectly fine before these updates. This being 
said, the newer ConTeXt version doesn't resolve the issue.

Observations:

1) Zint (and Inkscape) is in my PATH and correctly sym-linked as specified in the 
wiki (~/tex/texmf-osx-64/bin/lib/luametatex/zint/libzint.so 
). However, the library was (still) not fount after mtxrun 
--generate

[This seems an odd, but unrelated problem]

2) So, I hardcoded libfile in libs-impzint.lmt to

local libfile = "/usr/local/Cellar/zint/2.13.0/lib/libzint.dylib"

3) Running the wiki example:

   \usemodule[m-zint]
\starttext
\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

* With \usemodule[m-zint], I correctly get:

zint --barcode=qrcode  --output="zint-qrcode-495165e08dbc5ce650aaaf13caa2229f.eps" 
--input="zint-qrcode-495165e08dbc5ce650aaaf13caa2229f.tmp"
zint --barcode=maxicode  --output="zint-maxicode-098f6bcd4621d373cade4e832627b4f6.eps" 
--input="zint-maxicode-098f6bcd4621d373cade4e832627b4f6.tmp"

[Barcodes show up as expected]

* With \usemodule[zint], no success:

optional> using library 
'/usr/local/Cellar/zint/2.13.0/lib/libzint.dylib'
zint> something went wrong: invalid result vector
zint> something went wrong: invalid result
zint> something went wrong: invalid result vector

Maybe this is helpful to pinpoint the issue?

You asked for a list, that is e.g. a table of contents (list of numbered

If you want to affect itemizations, use \setupitemize (same as

%D possible to force a location by explicitly setting \type {location} to \type
%D {here}.
%D
%D Another way to force a certain order is to set the \type {order} variable

%D placing a list. The \type {command} option only pushes commands into the 
right
%D order, and \type {all} orders all entries (which might be too much). In this 
case
%D no specific location is needed with the inbetween method. Maybe additional
%D mechanisms show up some day. See \type {inbetween-001.tex} for an example.

I don't really understand what capability the comment is referring to let alone 
be able to create an example demonstrating the difference.


Thank you, so it looks like "location=here" is only used with 
\writebetweenlist to get the current page number.

I'm about to have a lengthy (2,000+ page) document published. Normally 
if it compiles and looks okay, I regard that as meaning no errors

even if something isn't displayed on screen as it should:


(1) I tried placing a table inside a startitemize environment, as 
instead of it not compiling, it left a message in the document warning 
that wasn't supported.


(2) In another case, I had an image that ConTeXt couldn't find, as I 
mispelled the filenmame, and it fully compiled and made a PDF, without 
me noticing.


(3) Or maybe in some case, a font couldn't be found for a specific 
character, so a single character in the file isn't displaying.


Those are just some examples; I intended for something to be printed on 
the PDF, but it isn't showing there.


Since a document of this size will have a lot of messages, is there a 
way to adjust the settings, from "show everything" to "show some" to 
"show only serious errors"? Or maybe to use > to send the errors to 
another file for careful study? (using Linux if that matters)


You can enable trackers like

\enabletrackers[figures.*]

But that just gives more log messages for debugging.

You get the list of all trackers with:

context --global m-trackers.mkiv


For your use case, directives are more helpful, like

\enabledirectives[logs.errors=*] (i.e. break at every error)

AFAIK that just handles missing characters, references and modules ATM, 
but this information might be outdated.


You get all directives with

context --global m-directives.mkiv

Your critique applies to JUH’s quote, though.

I used “infamous” as a funny way to say “not famous, but somewhat known”

The “infamous” alternative to LaTeX

While most designers use graphical tools, there are still areas where 
code-based typesetting systems are fun, make sense or are even superior. 
While LaTeX is the most known of these, ConTeXt is used by a growing 
minority of ambitioned enthusiasts around the world.


The small but active and creative community of ConTeXt users and 
developers is always driving TeX development over new frontiers:

NTS, MetaFun, Oriental TeX, LuaTeX, mplib, LuaMetaTeX…
They’re also dubbed the incisors (AKA cutting edge) of the dinosaur of 
Open Source.


ConTeXt is aimed at creative users, known for advanced features like 
extensive font control and direct XML processing, with a deep 
integration of Lua and MetaPost.


---

ConTeXt was invented in the 1990s by Hans Hagen and Ton Otten of the 
Dutch company “Pragma Advanced Document Engineering” for typesetting 
schoolbooks. Taco Hoekwater refactored the TeX source code to create 
LuaTeX which was further developed into LuaMetaTeX by Hans Hagen (and 
lately Mikael Sundqvist for refined math typography).


---

“To be fair, switching to the ConTeXt way of thinking and doing things 
was not an overnight process […]. But once I got used to it, I could not 
imagine going back to LaTeX. I’ll go even further and say that, in my 
view, ConTeXt is the future of TeX.

(Prof. Idris Samawi Hamid, 2009)
Source: www.tug.org/interviews/hamid.html

“ConTeXt is LaTeX done right. It is simple, flexible and powerful.”
(J. U. Hasecke on Mastodon, 2022)

Is ConTeXt for me?

If you want …
* to design your own layout
* best quality math typesetting
* to use Lua functions e.g. for processing data
* deep integration of a graphics language (MetaPost)
* to process XML input
* no package conflicts
* to use OpenType features
* consistent setup commands
* to place stuff on layers
* visual debugging features
* to have a lean, but mighty TeX system
* to typeset much faster than with LaTeX
* high quality Arabic typography
… then ConTeXt is for you!

The sourcecode of the plugin is broken but easily fixable:

Then pdf->tex works with synctex from TeX live, "--synctex=repeat" and a 
right click in the viewer.


Sigh, should I learn TypeScript to adopt the viewer plugin and enable my

At least, this is what

But you can do implicit conversion of TIFF to PDF if you have the 
converter installed. (Maybe you've had that installed before?)


EPS, BMP, GIF, TIFF (and in MkIV, SVG) are only supported via conversion.
For EPS you need GhostScript (gs), for SVG Inkscape, and GraphicsMagick 
(gm convert) for the others.

[NTG-context] Re: Wiki - test/proposal to further clarify documentation

[Henning Hraban Ramm]

Hi Garulfo,

I’m not against the “new order”, but I’d keep the colorful subject 
tiles. Different accesses are good IMO (as long as it doesn’t get to 
convoluted).


I’d say updating, sorting, restructuring pages is more important than a 
new start page.


Yes, please sort out reference vs. tutorials!

Often examples make sense in the reference pages, so the distinction is 
a bit fuzzy, but there are enough where a subject/tutorial page would 
make more sense than examples spread over several single command pages.


We could also define if the “main” reference page (with examples) is 
\definestuff, \setupstuff, or \stuff – IMO \setupstuff makes the most 
sense, since usually the others inherit from it.


Often enough, parameters aren’t explained in the reference pages; 
sometimes you can find examples using them, but there are too many 
holes. I tried to fix that where I could, but too often I don’t 
understand enough of the sources to make sense of some setting.


For wiki contributors, it might make sense to combine the markup pages – 
in many pages e.g.  is used where  would 
make more sense; often \starttext … \stoptext is not necessary and just 
blows up examples; markup is generally somewhat chaotic (e.g. , 
, or ``?).

I just discover the Diátaxis documentation framework :

- 30min video : "What nobody tells you about documentation", 
https://www.youtube.com/watch?v=t4vKPhjcMZg  , from Daniele Procida at PyCon 2017

As I understand it, it can help both readers and writers of the documentation 
by clarifying the purpose of each element.

So I started a potential new "welcome page" :  
https://wiki.contextgarden.net/Main_Page2

The main lines would be :
- Tutorials: installation pages, step by step examples
- How-to guides: most of the existing wiki pages which are not 
https://wiki.contextgarden.net/Commands/ ...
- Discussions and manuals: most of the existing manuals
- Reference : the pages dedicated to commands which already include link to 
mailing list, stack exchange, ConTeXt's source
   - https://wiki.contextgarden.net/Category:Commands
   - https://wiki.contextgarden.net/Special:PrefixIndex?prefix=Command%2F

To match the logic of Diátaxis, maybe some material from command pages should be moved from 
"Reference" to "How-to guides",
for example, when the examples go beyond "pure description" and begin to deal with 
"how-to" cases, e.g. :
- Reference for setuphead: https://wiki.contextgarden.net/Command/setuphead
- How-to guides for headings: https://wiki.contextgarden.net/Titles

If it make sense, and according to your feedbacks, I can continue to reallocate 
existing contents.

Thanks for your feedback and thoughts.

Hi all,

Is it on purpose that 128 pages

I didn't find an explanation in https://wiki.contextgarden.net/Command

For example, these two pages exist :
- https://wiki.contextgarden.net/Command/startbuffer
- https://wiki.contextgarden.net/Command/_startbuffer

If it is on purpose:
- What is the purpose, and which page should contain which documentation?


The command pages which start with an underscore are probably leftovers
when Taco changed a page from manual command descriptions to auto
generated tables.

In the process to change the page he makes a copy of the current page
with an underscore at the beginning which is deleted after the change
but it's possible he forgot to delete a few of them.

When you notice no difference between both versions of a command page
you can delete all of the forgotten pages.


No!

These are the general pages in opposite to instance pages, e.g. 
"startsection" and "startchapter" are instances of "_startsection"?


https://wiki.contextgarden.net/Command/_placefloat is the general page 
for the instances placefigure, placetable etc.

Oh, as usual with PDF association…


Sorry that pdf/UA-2 costs something is due to ISO not to the PDF
association. The PDF association made the WTPDF document which is
for free (and is very similar to pdf/UA-2). And imho they are also
trying to get sponsors for PDF/UA-2 (something they already did for
the PDF 2.0 spec which you now can buy for 0€).


Ok, sorry for barking at the wrong tree!

And I guess DANTE as a member of PDF association has access to the 
documents anyway?

[NTG-context] regular online meet-up

[Henning Hraban Ramm]

You’re invited to our regular online meet-up, this upcoming
Wednesday, April 10th, 19:00 CEST (UTC+2)

at https://lecture.senfcall.de/hen-rbr-rku-oke
(same, but shorter: https://u.mtxrun.eu/ctxmtg)

ConTeXt users of all levels are welcome!

Do you have a subject that you’d like to talk about?

Looking forward to seeing you,
Hraban


(Same blurb as always:)

[Howto]
* No special software installation required; most modern browsers should 
work (WebRTC required).

* Open the URL above, accept the privacy statement,
* enter your name,
* click "join" (or "start" if you’re the first),
* click "with microphone", allow your browser to access it, check the audio.
* Your microphone is muted if you join. Activate microphone and/or 
camera with the buttons at the bottom.

* Minimize the default presentation with the "screen" button, bottom right.

* If you’d like to share your screen or upload a file, you can make 
yourself the presenter: Click on your user name, change the setting, 
then you’ll see the "screen sharing" button beside the camera button; 
also there’s now "manage presentations" behind the "plus" button.
Beware there is only one presenter at a time, so don’t kill someone 
else’s presentation.


[Technical hints]
* Sound is usually better if you use a headset (less noise for everyone).
* Connection problems are mostly due to low bandwidth or high latency on 
your side, e.g. with mobile connections.

* Sometimes leaving and re-entering helps.
* If audio/video doesn’t work for you, you can still use the text chat.
* Screen sharing needs a lot of bandwidth.
* BigBlueButton documentation applies: 
https://bigbluebutton.org/teachers/tutorials/


[Netiquette]
* Please use a name that we recognize from here. Some feel uncomfortable 
with anonymous lurkers.

* Mute your microphone while you’re not talking.
* It’s nice to show your face at least when you join.
* If there are connection problems, stop camera sharing.
* The room is set to “everyone’s a moderator“, I trust you...

Of course.

But you asked for wanted accessibility features:

We have \pdfbackendactualtext{visible}{alternative}, can we get

Not automatically, of course (if someone wants AI descriptions they can 
implement a module), just as a keyword in \externalfigure?

[NTG-context] PDF/UA-2, WTPDF

[Henning Hraban Ramm]

Quoting a post by Philipp Kiff, 
https://mastodon.social/@pkiff/11221949350928:



In amongst the release of PDF/UA-2 (PDF for Universal Accessibility) and 
the new Well-Tagged PDF (WTPDF) standard last month, some PDF 
professionals may have missed two other new resources that may help 
explain and view them:


1. Questions and Answers about Tagged PDF from PDF association

2. Acrobat Custom File Info Panels by Peter Wyatt


Last month saw the release of PDF/UA-2 and the new Well-Tagged PDF 
(WTPDF) standard - neither of which revokes PDF/UA-1. And none of those 
are the same as PDF 1.7 vs 2.0. To many, the landscape of PDF specs may 
now seem littered with confusing acronyms and versions!


For some help disentangling it all, the PDF association has a Questions 
and Answers about Tagged PDF:


https://pdfa.org/resource/tagged-pdf-q-a/


In related news, Peter Wyatt released Acrobat Custom File Info Panels. 
This is a free extension for Acrobat that adds new panels to the XMP 
metadata shown when you view File > Properties in Acrobat Pro.


The new panels allow you to view the additional conformance claims and 
dated revisions of ISO standards that can now be included in PDFs, but 
that aren't currently visible in the standard Acrobat panels.


https://pdfa.org/discovering-pdf-metadata/


One thing I realized in reading through the new standards and looking at 
various sample files this week is that I should probably spend some time 
learning LaTeX! Both LaTeX and LibreOffice are already capable of 
producing PDF/UA-2 files, and with some tweaking, LaTeX can produce what 
appear to be really good WTPDF files. Kudos to both those development teams!


https://github.com/latex3/tagging-project/discussions/72


Finally, in case you missed earlier posts from last month, here are 
links to the official sources for the two new PDF standards that these 
other resources relate to:

[NTG-context] Re: incosistent output of --- dash

[Henning Hraban Ramm]

Am 06.04.24 um 11:43 schrieb madiazm.eo...@gmail.com:

Hi everyone,
I'm a bit puzzled because I usually don't get an em-dash when I type tree 
hyphens. If I use the command \emdash, no problem but when I use the hyphens 
some days it works... and somedays I see three small hyphens.
I tried it on overleaf and of ContextOnWeb with the same inconsistency. If I 
create a new file it usually works right; but when I overwrite an existing file 
subtituting a hyphen for three where the dash should be I sometimes get it 
right and sometimes wrong.
It is not the pdf viewer since I get good or bad results in all, the overleaf 
pdf preview tool, the context on web preview tool and the mozilla integrated 
pdf viewer.

Am I missing something on the use of this ligature? (the question is just out of 
curiosity, since I plan to create a command that adds a hairspace after or before the 
dash, since I don't like it to stick to some letters like "o".


Generally, “we” try to reduce active characters as much as possible, 
that’s why -- and --- usually /don’t/ produce en or em dashes. You can 
activate these ligatures as a font feature though (AFAIR "latexhyphens", 
can’t find it…).


Some editors and some fonts do automatical replacements.

[NTG-context] statistical charts module re-published

[Henning Hraban Ramm]

Hi,
since the Akela server at Mendel University is down since a while, I got 
no response from Tomáš, and it would be a pity to lose this module, I 
re-published the statistical charts module at 
https://codeberg.org/fiee/context-statistical-charts

I’ll also put it on modules.contextgarden.net

This is version 0.31, tagged by me as 2020-09-11 (date of the presentation).
I’m sure there’s a newer version somewhere, at least at Ramkumar’s, and 
I’d like to update the repo to that.

Also the sources for the documentation are missing.

Authors, please help me save your work!

[NTG-context] international type design

[Henning Hraban Ramm]

Have a look at these beautiful font designs:
https://esadtype.esad-amiens.fr/
Unfortunately the fonts are not available (yet).

Take your time to browse the papers about intention, design process etc.

I just browsed the dissertation about the (Vietnamese) "Dilinh" font and 
found the considerations interesting.


"Gul" has matching Devanagari & Latin, "Tarisel" has variations from 
readable text to abstracted lombardic unciale, and "Wierd" has matching 
deconstructivist outlines for Arabic & Latin…

Thank you!
And when would you suggest what?

A float I’d use only if I need caption/numbering or the floating feature.

When I tried line correction, it never helped; probably I used it wrong 
(e.g. around section titles).



I wanted to document it, but can’t find it in the sources:


The definition is in spac-ver.mkxl.


Thank you!

So, "context --find" does not what I thought it would.


AFAIR the find option searches only the manual sources.


Looks like it. So I should use grep (mtxrun --script grep).

[NTG-context] context editor support / syntax highlighting for Pulsar

[Henning Hraban Ramm]

Hi Hans (et al.),

find attached a slightly extended version of the "interface" script that 
can also generate the list of commands in cson format for Pulsar/Atom.


It just creates a basic list of commands for syntax highlighting; for a 
complete plugin, "grammars" and "settings" are missing, see 
https://codeberg.org/fiee/language-context
(Yes, this approach is oldfashioned and a plugin could do a lot more, 
but I don’t speak TypeScript.)


The generated cson file is for "snippets", like in:
https://codeberg.org/fiee/language-context/src/branch/master/snippets/language-context.cson

There, I added information from the interface files and also from the 
wiki, if existing. I don’t know how to do that in the lua script.


---
function flushers.pulsar(collected)
for interface, whatever in next, collected do
local commands = whatever.commands
local environments = whatever.environments
local result, r = { }, 0
r = r + 1 ; result[r] = "'.text.tex.context':\n"
for i=1,#commands do
r = r + 1 ; result[r] = format("\t'\\%s':\n",commands[i])
r = r + 1 ; result[r] = format("\t\tprefix: 
'%s'\n",commands[i])

-- can we have some information?
--r = r + 1 ; result[r] = format("\t\tdescription: 'level: 
primitive; interface: i-tex.xml'",'')

-- no URL if command starts with "stop"
r = r + 1 ; result[r] = format("\t\tdescriptionMoreURL: 
'https://wiki.contextgarden.net/Command/%s'\n",commands[i])

end
io.savedata(format("language-context-%s.cson",interface), 
concat(result),"\n")

end
end
---

Also, the "en" interface is empty, everything is in "common", so the 
iteration over interfaces makes no sense here.



Actually, Atom/Pulsar could work with a tree sitter parser 
(https://github.com/pmazaitis/tree-sitter-context), but I don’t know how 
to use it.



[TextMate]
For TextMate and other editors that use TM bundles, it might make sense 
to update https://github.com/pgundlach/context.tmbundle
At least the list of commands could be automatically converted from the 
interface files, but it’s more involved than what mtx-interface does.



[Visual Studio Code / VSCodium]
BTW, is the ConTeXt language server for VS Code public anywhere? 
(Ramkumar KB promised…) Or is "mtxrun --script=vscode --lsfile" the same?

I have code like this:

I need some images to appear in a book. I need them to keep their proper 
ratios, but scale up to the maximize the available space.


The image can't be more than \textwidth wide, and can't ever be more 
than 1.2\textwidth high.


The problem I am getting with this code, and it does seem to be limiting 
the images to be not bigger than those two dimensions above, is some of 
the images, for reasons I can't understand, are appearing really tiny 
and aren't scaling up to fill as much space as is possible. I can't 
explain why this is happening--the images themselves are very very high 
resolution.


Is there any way to modify the code to make sure the image stretches up 
to be the biggest it can, without exceeding the sizes I've listed?


Hi Joel,

AFAIK, if you don’t set at least either height or width, ConTeXt uses 
the image’s resolution setting to calculate its size, and that is often 
useless.


(Maybe there’s also something wrong with ConTeXt’s max width/height, I 
don’t know; I’m still planning to carefully check all options of image 
processing…)


You could try if "factor=fit" or "factor=max" yields the results you want.

Rename the section, then you don’t need marking.

Sorry, I'm in a hurry and must look up how to get the number…

I know \setupheadertexts, but do not know what shall I write here:

If I write marking=Aufgabe I get Aufgabe, no number! For chapter the same.

[Hraban Ramm]

Hi Andrés, thank you!

Am 20.03.24 um 06:07 schrieb Andres Conrado Montoya:
I have found with experience that a formula to calculate the binding 
correction for a saddle stitch binding, not more than 4 pages in a 
signature (only one fold in the middle) usually is 1/2 the 
circumference of a circle with radius /r/, being /r/ the thickness of 
the paper times the amount of physical signatures. Something like: 
\frac{π \times t \times s}{2}. I have not tried a formula for more 
folds in a signature.


The thing is, you have to recalculate for each signature fold. The 
innermost will have displacement zero, the second one a little bit 
more, the third a little bit more, and on and on until we reach the 
outermost signature.


However, it is necessary to say that unless you are using a 
particularly thick paper, or you are using too many pages for a saddle 
stitch bind (my personal and professional opinion would be no more 
than 80, but better 60), the displacement is usually negligible.


For example, let's say the paper thickness is 0.1 mm (which is 0.0001 
meters) and there are 40 pages in 10 signatures. The radius would be 
0.0001 meters per signature * 10 signatures = 0.001 meters. Then, half 
the circumference would be 1/2 * 3.14159 * 0.001 meters ≈  0.0016 
meters or 1.6mm at the last signature. Unless there was a displacement 
of more than, say, 4 mm, I wouldn't worry too much about it.


E.g. our Bonn architectural guides 
(https://www.dreiviertelhaus.de/reihen/afb/) are saddle-stitched 
booklets, usually have 60 pages and are printed on 115g coated paper. 
With coated paper you can’t really derivate the thickness from grammage. 
The horizontal page shift is visible if you look carefully. But since 
the paper is not very transparent, you only see the problem if you look 
for it. I don’t arrange the pages myself, don’t know the signature size, 
and I can’t request specials, since we must print cheaply to keep the 
low price (had to raise it from 5 to 8 € anyway, half of it goes to the 
wholesaler).

I organise this always with correction to the backspace.

For every single page?



Theoretically the shift value should be the same as the paper thickness (don’t

sense?

I think that this would be quite cumbersome, paper thickness of higly coated 
papers vs. novel-printing paper… I believe one would have to establish this 
thickness for each project unless the same paper is used...


No, I meant, I'd use the actual paper thickness as a parameter, so that 
paper shift could be calculated automatically with a geometrical factor 
according to the imposition schema. Don't you think that makes more 
sense than setting it for single pages?


But while this is an interesting topic, it's one of these overly 
involved niche features in ConTeXt… I didn't care too much myself, and 
laypeople don't see it anyway.





Unfortunately I threw out my old books on printing technology long ago, and my 
newer one doesn’t cover bookbinding (I’m not at home anyway).

I think, that many printshops do not possess neither old books including 
bookbinding nor do they care about the wishes of the binder … Pity, that you 
threw them out, but i understand, that circumstances might be such that you 
have to take decisions…


When we left Switzerland in 2012 for Freiburg (and then again Freiburg 
in 2013 for Kyrgyzstan), we had to drop ballast, and I still had too 
many books (if you can have too many books at all…). I had a lot on art 
techniques like calligraphy that I never used, and my printing 
technology stuff was outdated – well… The antiquarian gave me 30€ for a 
big pile of formerly expensive books, and he probably was generous.


Since then I gained a publishing house and had to move three times, my 
moving helpers were not amused about that many book boxes. (The last 
move was into the 3rd story, or is this 4th?, of an old house with very 
high stories; if visitors arrive panting at my door, I tell them they 
can sign the summit register now…)

I didn’t think about vertical pageshift, but of course that’s also

I'm not sure how (horizontal) pageshift is supposed to work with full

edge should be enough.

Hi Hraban,

I think we should clarify this.

Binding correction is a fixed amount of whitespace in the spine added to the 
inner white-space. This is to ensure, that the binding, which is consuming 
white-space, keeps the inner white-space optically as intended..

The page shift mechanism works only with imposition enabled. This ensures, that 
the type-setting area does not creep towards the spine because multiple sheets 
of paper are folded in the spine.

I doubt whether it is enough to have the measure of the thickness do determine 
this creeping effect, because we are making folds which are probably more 
circles than just adding thickness of paper.

Hi Wolfgang, thank you! Seems like I was too dense to understand the 
description for the \setuplayout parameters in the wiki (and there are more 
that I never used, oh my…), and since I never use ConTeXt’s imposition for 
serious print products (and never set up a scheme myself), I didn’t know about 
pageshift.

Ok, if I leave imposition to the printshop and they don't do binding correction 
in their workflow, I'd need to set horoffset differently for every single page 
(i.e. first, second, second-to-last and last the same; 3th, 4th and from back 
the same etc.). Or is pageshift applied independently from arranging?

And then, it makes no sense to add the same value all the time. I don’t know if BCOR 
works this way in LaTeX, but one value (paper thickness) should be enough in combination 
with an imposition schema. I.e. if I define a paper thickness and the number of pages 
that are in one booklet (as a single booklet or part of a "proper" book), then 
the page shift should work automatically.

Well, for a single booklet, it could. In a book, booklets can have different 
numbers of pages, and then you'd need to define a list… Okay, too complicated. 
It’s the printshops's responsibility anyway, and nobody complained about my 
books so far. (I'm not perfectionist enough to care.)

Hi Jeroen,

it might make sense to use

I would use one command for number and title and put both in the same

Yes, please! The version that you gave me a year ago is already really

So I get a prominent marker in the content and the title of the affected

There have been many changes along the way, and maybe at some time
some things were not really working, but later fixed.

parameters backspace and cutspace.


backspace is the inner margin and cutspace the outer

Hi Wolfgang, thank you! Seems like I was too dense to understand the 
description for the \setuplayout parameters in the wiki (and there are 
more that I never used, oh my…), and since I never use ConTeXt’s 
imposition for serious print products (and never set up a scheme 
myself), I didn’t know about pageshift.


Ok, if I leave imposition to the printshop and they don't do binding 
correction in their workflow, I'd need to set horoffset differently for 
every single page (i.e. first, second, second-to-last and last the same; 
3th, 4th and from back the same etc.). Or is pageshift applied 
independently from arranging?


And then, it makes no sense to add the same value all the time. I don’t 
know if BCOR works this way in LaTeX, but one value (paper thickness) 
should be enough in combination with an imposition schema. I.e. if I 
define a paper thickness and the number of pages that are in one booklet 
(as a single booklet or part of a "proper" book), then the page shift 
should work automatically.


Well, for a single booklet, it could. In a book, booklets can have 
different numbers of pages, and then you'd need to define a list… Okay, 
too complicated. It’s the printshops's responsibility anyway, and nobody 
complained about my books so far. (I'm not perfectionist enough to care.)

[NTG-context] Mikael’s missing math manual

[Hraban Ramm]

… and another thing that came up in my workshops and in discussions at 
our booth: the math manual is eagerly awaited! (My book too, but I can’t 
answer most questions about math.)


One participant tested some math alignment examples from an older paper 
by Aditya and found them working in her current LMTX installation but 
not in COW – I know it runs an older version, but Aditya’s article was 
even older…

[NTG-context] can we do binding correction?

[Hraban Ramm]

Hi, this question was rised in my ConTeXt beginners workshop* at 
Chemnitz Linux Days today:


Can I configure binding correction for saddle-stitched or thread-bound 
booklets, and if, does it only work with arranging (imposition) or can I 
enable it somehow for the layout (if the printshop does the imposition)?


Also I recognized I'm not sure about the difference of the layout 
parameters backspace and cutspace.


Hraban

*) 8 participants who endured 3 hours of me mostly talking… Further 
questions that I couldn't answer for sure were about PDF/A or PDF/UA and 
how color profiles are handled within ConTeXt and at printshops (my 
monitor is profiled, but I know I have to edit images "too bright" to 
have them look right in print). I need to investigate further before I 
can ask precise questions.


When JUH yesterday had his shorter talk about "corporate publishing with 
Markdown and ConTeXt", the lecture hall was stuffed.

Hi Hraban & Seyal

I can confirm that converting the *.svg file into a *.pdf file displays 
the colour shades correctly ...

(I used Gimp to export the smile.svg file to a smile03.pdf file).


Gimp is a really bad choice in this case, since it converts vectors into 
pixels.

And if you place a PDF, no further conversion is needed.

If you have problems with SVGs, use Inkscape (or some commercial 
alternative like Affinity Designer or Adobe Illustrator) for PDF conversion.


The MWE below works correctly, even if you have to make finer 
adjustments to place the figure in a precise position on the page. As 
I'm in the process of enriching and clarifying a few pages of the 
ConTeXt wiki and the French wikibook, I'm interested in the details 
concerning the position of figures, images and photos etc. So please let 
me know (in private mail) how you make your documents (a MWE will do).


Position options:
* relative placement as floats, i.e. \placefigure
* absolute placement on layers, i.e. \setlayer
* relative corrections with \offset (also within floats)

* No special software installation required; most modern browsers should 
work (WebRTC required).

* Open the URL above, accept the privacy statement,
* enter your name,
* click "join" (or "start" if you’re the first),
* click "with microphone", allow your browser to access it, check the audio.
* Your microphone is muted if you join. Activate microphone and/or 
camera with the buttons at the bottom.

* Minimize the default presentation with the "screen" button, bottom right.

* If you’d like to share your screen or upload a file, you can make 
yourself the presenter: Click on your user name, change the setting, 
then you’ll see the "screen sharing" button beside the camera button; 
also there’s now "manage presentations" behind the "plus" button.
Beware there is only one presenter at a time, so don’t kill someone 
else’s presentation.


[Technical hints]
* Sound is usually better if you use a headset (less noise for everyone).
* Connection problems are mostly due to low bandwidth or high latency on 
your side, e.g. with mobile connections.

* Sometimes leaving and re-entering helps.
* If audio/video doesn’t work for you, you can still use the text chat.
* Screen sharing needs a lot of bandwidth.
* BigBlueButton documentation applies:

[Netiquette]
* Please use a name that we recognize from here. Some feel uncomfortable 
with anonymous lurkers.

* Mute your microphone while you’re not talking.
* It’s nice to show your face at least when you join.
* If there are connection problems, stop camera sharing.

With latest LMTX (2024.03.05), b and d are slanted, as I would expect.

This might be just a test case, but I’d avoid switches like \em without

Hi Ursula,

The reason for which you did not get the expected result is that you 
have « } » missing in your file, that is the closing brace after your

« {\it » at the end of your document.
Moreover you did not have a \stoptext in your file, and a math command « 
\m » was not written correctly. Talking of math, I personnaly prefer to 
enclose in-line math between dollar signs $, that is writing « $\exists 
x \in H$ » instead of  « \m{\exists x \in H} ».


Well, better stay with the modern ConTeXt approach of \m{}.

Also, you can use

mtxrun --script check yourfile.tex

to look for missing braces, stops etc.

[NTG-context] enhancing documentation: initials

[Henning Hraban Ramm]

Hi, I tried to figure out what the "method" parameter of \setupinitial 
does – it changes the handling of quotation marks at the beginning of 
the text. It’s defined in context/base/mkiv/typo-drp.lua


But I found no difference between first, last, and none; just "auto" 
includes the mark in the initial, and it works only with a few 
languages, e.g. English and French, but not e.g. German or Dutch:


"""
\mainlanguage[de]
\setuppapersize[A6]
\setupinitial[n=2,color=orange,]

\starttext
\start
\setupinitial[method=first]
\placeinitial \quotation{Keine andere Kunst hat mehr Berechtigung, ihren 
Blick auf die zukünftigen Jahrhunderte zu richten als die 
Typographie.}\wordright{Giambattista Bodoni}

\stop

\start
\setupinitial[method=last]
\placeinitial \quotation{Nationalökonomie ist, wenn die Leute sich 
wundern, warum sie kein Geld haben.}\wordright{Kurt Tucholsky}

\stop

\start
\setupinitial[method=auto]
\placeinitial \quotation{Der Mensch wird auf natürlichem Wege 
hergestellt, doch empfindet er dies als unnatürlich und spricht nicht 
gern davon.}\wordright{Kurt Tucholsky}

Not compile the engine (luametatex), but re-make the ConTeXt format with
context --make
and to be on the safe side, regenerate the file database with
mtxrun --generate

Thank you all for your suggestions and contributions to the wiki.

I don't intend to nag, but when looking at what ConTeXt is producing, I 
need to state that the result is still far away from a properly typeset 
Japanese text.


That’s the result of apparently nobody having an interest in it and the 
developers not knowing enough about CJK.
(Look at Arabic: Without Idris and the funding for OrientalTeX, the 
support would be just not there.)


Often enough people demand features but don’t stay long enough to evolve 
them until they’re “ready for prime time”.


Now it’s your chance to make it better.
Don’t give up.

Dear Dalyoung,

Thank you very much for your insight. I downloaded the Noto Serif JP 
fonts and set up a fontfamily as you indicated, by adding

\setscript[nihongo]
which solves a problem I had with line breakings. And everything works 
smoothly!


So, for the mail archive, here is what I have and what works fine:

%%% Noto Fonts

\definefontfamily[JapaneseFont][rm][Noto Serif JP]
   [   it={style:regular,features:{*,slanted}},
       sl={style:regular,features:{*,slanted}},
       bi={style:bold,features:{*,slanted}},force=yes]

   [   it={style:regular,features:{*,slanted}},
       sl={style:regular,features:{*,slanted}},
       bi={style:bold,features:{*,slanted}},force=yes]

\definefontfamily[JapaneseFont][tt][Noto Serif JP]
   [   it={style:regular,features:{*,slanted}},
       sl={style:regular,features:{*,slanted}},
       bi={style:bold,features:{*,slanted}},force=yes]

\definefontfamily[JapaneseFont][math][Tex Gyre Termes Math]
%\definefontfamily[JapaneseFont][math][Tex Gyre Pagella Math]
%\definefontfamily[JapaneseFont][math][Tex Gyre Aventor]



\setupbodyfont[JapaneseFont,12pt]
\setupruby[location=top,voffset=-2ex]
\setupwhitespace[big]
\setscript[nihongo]

\starttext
\ruby{早}{はや}く。
いきましょう。
\stoptext

Best regards: Otared


Thanks all contributors, I added this to 
https://wiki.contextgarden.net/Chinese_Japanese_and_Korean


I guess you also should set \mainlanguage[ja], I added it, also 
\mainlanguage[kr] for Korean.


I don’t know if the setups for Chinese and Korean are still valid, I 
just removed \setencoding.

Does anyone have a simple setup of fonts to write a small Japanese document 
(possibly with furagana) ? I am using MacOS and I have several Japanese fonts 
on the system.
I have some old examples which do not typeset correctly now, maybe because they 
use the old module simplefonts and  commands such as \setcjkmainfont and 
friends.


Try to replace the simplefonts calls with something like

\definefontfamily[myfonts][rm][SomeFont]
\definefontfamily[myfonts][ss][SomeOtherFont]

\setupbodyfont[myfonts,rm,12pt]

With Latin fonts, it usually works.

Looks like the unset TEXMF and TEXMFCNF envars are a problem.   What
should they be set to and where should they be set?


Usually, you don’t need to set any variables.
The default configuration file is also fine.

Does "context --version" work?

I tried to load the module only in the section where I need it, that 
lead to strange errors in later sections, apparently there’s no 
encapsulation.


If I comment line 289 in m-scite.mkiv that reads
--visualizers.register("tex",   visualizer)
it works for me.

Would it be possible to unregister a visualizer, or is the call maybe 
unnecessary anyway?

Hello,

I've been away from ConTeXt for some time but now I want to install it
on my FreeBSD 13.2 system(s) (I have not switched any machines to 14.0
yet).  After unpacking, running the install scripts results in:

ld-elf.so.1: /home/rmason/Software/Context/bin/mtxrun: Undefined symbol
"__libc_start1@FBSD_1.7"

I assume this is because mtxrun is compiled for FreeBSD 14.0.  Thus, I
need (I think) to compile it for 13.2.  Are there instructions somewhere
on how to do this?

If I get a working installation I'm happy to contribute the FreeBSD 13.2
binaries back to the project, if someone will tell me how.


Yes, we need to document it in the wiki…
But it’s easy:
cd into your tex/texmf-context/source/luametatex
and run build.sh
then copy the "luametatex" binary from build/native
into tex/texmf-/bin/

of the cell).


 begin example
\startuseMPgraphic{dottedborder}
   draw OverlayBox withpen pencircle scaled 2 dashed withdots withcolor 
"red";

\stopuseMPgraphic

\defineoverlay[dottedborder][\useMPgraphic{dottedborder}]

\starttext

\bTABLE[frame=off,background=dottedborder]


Thank you!

Since I needed only horizontal lines, I forced the height with an 
“invisible“ line:


\startuseMPgraphic{dottedborder}
   draw (0,0)--(0,OverlayHeight) withpen pencircle scaled 0.001 
withcolor white;
   draw (0,0)--(OverlayWidth,0) withpen pencircle scaled 2 dashed 
withdots withcolor "red";

\stopuseMPgraphic

… but it would be visible on a colored background. I’m sure you can show 
me a better way…


My real life example (p.2 in https://yemaya.fiee.net/s/DEEHs5m49yftiqW) 
involves sketchy lines, and there it’s a bit annoying that the row is 
not its own frame that could get a continuous background… Well, it’s 
good enough, I’ll settle for it.

[NTG-context] Re: Text in Margin

[Henning Hraban Ramm]

Am 19.02.24 um 14:14 schrieb Jeroen:
In a textbook I am looking to place a large left margin at every page of 
each chapter. At left printed pages a left margin and at right printed 
pages a right margin, so like a double sided construction. In this 
margin I would like to place:


1. Keywords and small descriptions to emphasize some text from the textflow
2. Figures
3. An expansion of a table that is placed in the main textflow but that 
needs to cover a wider range then the text area so it expands into the 
margin


What is the the easiest way to achieve this?


Generally, you use \inmargin, \inouter etc.

Additional to Wolfgang’s suggestions:

If you need sidefloats that cover not only the margin but should 
decrease the text width, you can move sidefloats into the margin like:


\startplacefigure[title={},location=outer]
\offset[rightoffset=-\marginwidth]{\externalfigure[cow][width=0.5\textwidth]}
\stopplacefigure

Beware: it doesn’t work well with captions (I’ve still no solution that 
always works), and \offset understands only rightoffset and leftoffset, 
not outeroffset.
The example is on a right page; you must “pull” the image into the 
margin (rightmargin with negative value), if you try „pushing“ with 
leftoffset=\marginwidth, the text flow is wrong.
