Dear all,

some years ago I asked about how to process a csv file in a table with 
repeating headers on following pages, but got no answer.


https://www.mail-archive.com/ntg-context@ntg.nl/msg98903.html

Now I am again working on this problem.

I wonder if there is a better way to process csv files to a table with 
more flexibility?


Or do I simply miss the switch to mark the first row in the csv file 
as the header that has to repeat?


Did you try split=repeat instead of split=yes?


Oh, and of course you need a \bTABLEhead, otherwise there’s nothing to 
repeat.
That means AFAIK, the header can’t be part of the CSV, using this simple 
module.

depends .. three liners can be made to work in fact one should then use 
\widowpenalties and \clubpenalties with a high value for the first two 
entries (and maybe disable them to overlap)


I have
\setpenalties\widowpenalties{2}{8000}
\setpenalties\clubpenalties{2}{1}

Does this make sense? While I saw in your demonstrations that it’s 
possible to set different penalties per line, I never tried.


Otherwise, I found out the easiest solution is a \vbox, VZ does the 
rest. Should have thought of that earlier, would have saved me a few hours.



here is a teaser:

\permanent \specificationdef \lesswidowpenalties \widowpenalties

     \plustwohundredfifty \plusfivehundred
     \zerocount   \zerocount
\relax

used in upcoming new \setupalign options lesswidows and lessclubs 
because the above is not something that users should nother about.


These set high penalties for the first and last line, somewhat lower for 
the ones following and preceding.


We also have strictwidows and strictclubs that do your three thing.


Ok, I’m looking forward to it.

In case you wonder about the 'double' ... we can have different values 
for left and right pages because (we think that) on a spread a widow or 
club is less of a problem.


Fwiw, much of this of this already has been there for a while (as 
discussed at the meeting) but we're now integrating it into \setupalign 
and making sure that the overhead can be neglected.


Great!

I already do without grid, VZ works, HZ also should (I didn’t check 
with a tracker, and it’s not so extreme that I’d see it), but it’s not 
enough to automatically avoid single lines.


Indeed, so the stricter penalties combine well with vz


If a paragraph starts at page breaks, I can tweak the layout like
\page\setuplayout[narrow]. I defined narrow, normal, and wide versions 
with 1 mm difference. Before I didn’t know you can call named layouts 
like this, also relative page numbers like \definelayout[+1][wide] are 
nice.


If that’s not enough, I’m using \letterspacing with tiny ± values.

So much about dirty tricks. ;)


parpasses will permit you to have steps with different solutions so 
expansion can be delayed till it is really needed; interesting is that 
even with (say 8) par passes, most time the solution is found in the 
first (no hyphenation with 100 tolerance) or second pass (hyphenation 
with 200 tolerance) and the number last pass can be counted on one hand


Yes, you demonstrated several times. I just didn’t dare or was too lazy 
to delve into the “plain TeX” syntax to try.


(there are options to mark pararaphs and see what pass succeeded as well 
as overviews in the logs so that one can go to problematic places but 
that's for Keith to experiment with)


We're really surprised how well this all works on complex content (say 
very math intense, read: demanding wrt where to break).


If it also works with code examples, It’ll be great for the ConTeXt 
journal and my book.

Not intentionally. We're bringing widow and club penalties stepwise

Maybe try

It’s a bit unclear what your problem is.

Try
\setupuserpagenumber[numberconversion=romannumerals]

Instead of “romannumerals” you can also use r, R, or, or RK.

If you meant “Arabic” numerals, try n, N, o, or zero.

For the latter to work, you must add \startparagraph … \stopparagraph

There are some introductions linked in 
https://wiki.contextgarden.net/Documentation


Manuals written for MkIV still apply to LMTX, even if there are 
sometimes better alternatives to some constructs.


I don’t think plain TeX literature like Knuth’s TeXbook or Eikhout’s TeX 
by topic makes sense for a beginner, depending on what you want to do.


It makes no sense to try to learn ConTeXt on the dry; choose a project 
and overcome its problems one after the other. If you don’t have an 
application for TeX, you don’t need to learn it. What do you want to 
achieve?

[NTG-context] Downsampling images (again)

[Henning Hraban Ramm]

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

[NTG-context] syntax highlighting: pandoc uses Kate

[Henning Hraban Ramm]

Hi, since we recently discussed editor support and syntax highlighting:

Pandoc can use definitions from Kate[1] for syntax highlighting in a 
code block via "--syntax-definition".


There’s also ConTeXt support (MkIV/LMTX):

https://kate-editor.org/syntax/data/syntax/context.xml

Apparently, it can switch contexts to Lua, XML, MetaPost etc.
But the list of commands is quite short.

In case the author (Philipp A.) is listening: Is this intentional (“not 
necessary, highlight everything that starts with a backslash”)? 
Otherwise it probably would make sense to read in the interface files 
(i-*.xml).


I can’t tell if it would make sense to support this syntax via a module 
(like scite and vim). What we have if probably enough for most of us.

Thanks Bruce for your very helpful reply!

The reason for my question was indeed consistency, e.g. ensuring figure

Thinking more about it, the second solution you mention seems to be a better 
option, though - I can simply define the parameters in an external file and 
read it from both the PDF solver and ConTeXt to ensure consistency. Thanks for 
mentioning it!

Thank you also for mentioning \executesystemcommand, which I was not aware of!


Another option might be to use a marker such as

% DE_figure_here param1 param2 param3

in your ConTeXt source and then use 'awk' or another Unix text pre-processor to 
scan through for these, run the appropriate DE calculation, plot the graph and 
generate the appropriate \placefigure command to go in its place.

Bonus marks if it can automatically generate the caption based on the 
parameters! But if not, the marker can always follow the \placefigure macro e.g.

\placefigure
   {This is a DE showing something and something else}
   % DE_figure_here param1 param2 param3

so the awk code only needs to insert the image file name.

Note I’ve deliberately omitted the braces from the bit to be substituted so 
that you need to generate them in the awk. That way, if you forget to process, 
you’ll get an error not a missing image.


That sounds needlessly convoluted to me.
I’d use Aditya’s filter module to call external programs, it also does 
caching, i.e. if the parameters don’t change, it won’t waste processing 
time.

There’s the built-in asymptote module:

https://source.contextgarden.net/tex/context/modules/mkiv/m-asymptote.mkiv

I don’t know if it still works and if it could/should be improved.

There’s also Aditya’s filter module that alleviates calling external 
programs (I’m using it with LilyPond):


https://github.com/adityam/filter

But calling external programs is slow.

MetaPost is fast, (also) because it is integrated as a library.

It’s possible to address C libraries using Lua’s FFI (don’t ask me how, 
there is/was a manual).


Also, Hans announced to include some "2.5D" functions (perspective 
projections) into MetaFun soon. That might obsolete some uses of 
Asymptote. But a proper 3D model for MetaPost seems to be missing (not 
my expertise).



The second interest is in Aditya Mahajan's syntax highlighting module.
It is very nice but it invokes VI making the entire thing slow. I understand
the advantage of using VI is that we do not have to implement anything
when a new language comes. VI will have syntax highlighting and it will
be automatically done for us.


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.


There’s also the scite module that uses SciTE’s lexers for syntax 
highlighting. The builtin highlighters are limited to TeX/ConTeXt, 
MetaPost, Lua and XML.

I want to contribute to ConTeXt. I think that the steps for me should be:

1. Learn TeX
2. Learn LuaMetaTeX

and then I can approach the C code. It won't make any sense if I just
start reading the LuaMetaTeX code.


Sure, without a deep understanding of TeX it makes no sense to try 
anything with the C code.

Also, most of ConTeXt is written in Lua.

If you want to contribute, help with documentation – there are still too 
many commands and options undocumented in the wiki.
If you don’t understand enough of ConTeXt to do that, anything deeper 
makes no sense anyway.

Hello,
Assuming i am working in the first chapter, using \startplaceformula ...

Try \setupformula[prefix=no]

Otherwise look into the options of

[NTG-context] index entry with sorting and processor

[Henning Hraban Ramm]

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

\samplefile{ward}
\index{something}
\index{anything}
\page

\samplefile{tufte}
\GlIndex{something}
\GlIndex{anything}

[Henning Hraban Ramm]

I have a document with thousands of index entries. Here’s a sample code:
Some people lived in 
\index{cliff-dwelling}\index{dwellings+cliff-dwelling}cliff-dwellings, 
while others lived in \index{lean-to}\index{dwellings+lean-to}lean-tos.




I’m wondering if there is a short-cut means to set this up, such that if 
I can tell the 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 easier way to 
add these categories, then to go through the entire document and 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?


If it’s just a few instances, define a macro:

\define[1]\DwIndex{\index{#1}\index{dwellings+#1}#1}

For a list of words, a lookup table and a Lua function make sense.

With a comparable problem, normalizing location names, I used this:

-- lookups.lua
userdata = userdata or { }

userdata.Mapping = {
  ["Albano"] = "Albano (Provinz Rom)",
  ["Altona"] = "Altona (Hamburg)",
  ["Aurich"] = "Aurich (Ostfriesland)",
-- …
}

function userdata.Lookup(name)
  context(userdata.Mapping[name] or name)
end

\loadluafile[lookups.lua]
\defineregister[Location][]
\define[1]\LocIndex{\expanded{\Location{%

Yes, there are more of them.

Look into the lowlevel-registers document which describes how they are
created and also how you can define your own identifiers with \newuserunit.


Thank you! There must have been a manual, but I didn’t guess “registers” 
was relevant.



Questions:

How differs "1" from "2"?
* em fs



\NC em \EQ \the\dimexpr1em\relax \NC\NR % \emwidth
\NC fs \EQ \the\dimexpr1fs\relax \NC\NR % \globalbodyfontsize


Ok, so they can differ minimally; in my 10pt setup I get the same value.


* lw hs


lw stands for \linewidth which is the default value for rulethickness in 
\framed etc.


I mixed up \linewidth with \textwidth, thought the one was LaTeX and the 
other \ConTeXt, since we’re talking about rulewidth otherwise.



hs is just \hsize.


Then it makes sense.


* ph vh

ph is \paperheight.
vh doesn't exist.


Ok, I had mis-noted vh from some older talk, meeting, or whatever, and

Next try:

Apparently, \setupunit affects only \unit,
for \digits you still need \setdigitmode (and \setdigitorder).
Is this intentional?

Also, \spaceddigits works only with decimal point input and doesn’t 
react to any of the above settings, while \unit and \digits expect me to 
insert a thousands comma manually.

Does this make sense?

Is ePub still a file format that ConTeXt can output? Does it require a 
significant rewrite of ConTeXt document code to be produced or is there 
a simple way to output this format?


Yes, I stopped working on ePub and updating the wiki pages, but did you 
even try?


You need
\setupbackend[export=yes] (see https://wiki.contextgarden.net/Export)
and probably
\setupexport[alternative=html],
that creates the necessary content files, and then

mtxrun --script epub yourdocument

creates an ePub, as documented in https://wiki.contextgarden.net/ePub

Unfortunately, the ePub at least doesn’t work with Calibre. I need to 
check what’s actually the problem.


When I last worked with ePub and created that wiki pages, I used my own 
scripts to make a working ePub from the export. I need to update that 
code and then the wiki. Don’t hold your breath.


The HTML export got much better recently, it now generates SVG for math 
and everything else where you use \startimage … \stopimage.

Maybe you can just use that HTML code without an ePub container.

[NTG-context] OT: specifications and reality

[Henning Hraban Ramm]

Hi,

since Hans often refers to bad and changing “standards” (e.g. PDF, 
MathML, ePub…) and Taco told us about the mess of RTF: You’re not alone.


There’s the ONIX[1] XML standard for publication data, prominently used 
by the monopolist VLB (Verzeichnis lieferbarer Bücher, German catalogue 
of books in print).


A friend and I had the idea of an open book catalogue (for all 
publishers and bookshops that want to participate), and they’re setting 
up a proof of concept. Just got a message:


* The examples from the ONIX homepage have errors if you check against 
their “strict” schemas.
* The catalogue of our publishing house, exported as ONIX from VLB, has 
errors when checked against the “not strict” schema, i.e. VLB generates 
faulty data.


Beautiful standards…

I’m nearing the final stages of preparing a file for printing, which 
will be used to produce a textbook at a professional printer. The 
printer can accept PDF files, and I’ve been generating them using the

I’m wondering if this approach is producing the highest quality output 
for printing purposes. Is there anything additional I should consider, 
such as installing LuaTeX or running specific commands, or command-line 
switches, to ensure the best possible print quality?


For context, when I installed ConTeXt standalone, it didn't seem to 
include LuaTeX by default, though after I installed, it asked me to run 
context --luatex commands which didn't function, so I worry my install 
isn't giving the best-possible output.


The current version of ConTeXt, LMTX, uses LuaMetaTeX which is a greatly 
enhanced version of LuaTeX. You don’t need the older program for 
anything, if LuaMetaTeX works for you.


PDFs generated by ConTeXt are usually as good as possible.

Additional stuff you must consider for professional printing are
– colors (better use CMYK; use images with proper ICC profiles)
- bleed (if you have elements that touch the margin of the paper, they 
must go ~3mm over the margin)
– crop marks (also make sense only if you have elements that go over the 
margin.

– imposition (ConTeXt speak: arranging) only if your printer can’t do it

[NTG-context] no escaping with scite highlighting any more?

[Henning Hraban Ramm]

Hi, this used to work:

"""
\usemodule[scite]

% the setup doesn’t change the behavior, I think it used to.
\setuptyping[TEX][
  option=tex, % scite sets "cld"
]

\starttext

\startTEX[escape=yes]
\definemeasure[PageWidth][165mm]  /BTEX\hfill{\ss Dimensions}/ETEX
\definemeasure[PageHeight][239mm]

\definepapersize[DANTE][  /BTEX\hfill{\ss Paper size}/ETEX
  width=\measure{PageWidth},
  height=\measure{PageHeight},]
\setuppapersize[DANTE]
\stopTEX

\stoptext
"""

Without the scite module, escaping in \startTEX works, but I need the 
module for some other highlighters.


Is there a solution?

[NTG-context] regular online meet-up

[Henning Hraban Ramm]

Even if it’s just a few days before our in-person context meeting:

You’re invited to our regular online meet-up, this upcoming
Wednesday, August 14, 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?
Is there something we should discuss before the Lutten meeting?

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...

I know \language only as a switch, but Hans changed several macros so

[NTG-context] OT: lead chemistry

[Henning Hraban Ramm]

Guido Kühn, a design professor, caricaturist and avid manual typesetter, 
recently bought an old, empty cabinet for lead fonts. In that, he found 
a leftover piece of chemistry typesetting, made out of Berthold 
chemistry letters – nowadays exceptionally rare, since they were smelt 
down even earlier than other lead type.

[NTG-context] workflow tool: add to git

[Henning Hraban Ramm]

In case you organize your ConTeXt projects in git repositories:
"addtogit.py" is a little script that checks your log (or jlg) file for 
the local files used and adds them to the git stage. (No automatical 
commit so that you can check if you want these files.)

Leaves out auto-generated files like "m_k_i_v_*".
Needs Python and GitPython (pip install gitpython).

If you can create it with a macro, you can use it for a title.

This looks just like \framed and \rotate with \offset.

You will have to post a true minimal example including the correct definition

Besides that, try a % at the end of each line of your macro and a comma

[NTG-context] spreadsheet module

Hi, I checked the spreadsheet module for the first time (in my own 
invoices I do everything in Lua and don’t need it).


In the attached example, I setup a decimal comma, as usual in German:
\setupspreadsheet[rechnung][
period={,}, comma={\,}, split=yes]

Unfortunately, this also replaces all dots in the text strings.

Is there a workaround (beside using \getspr in a “real” table)?

Apparently, \startrow or \startcell don’t understand the period setting.

(With "latexmk -recorder somelatexfile" I get the file list as a .fls file.)

My goal is to commit all used images to my git repo, while I often have 
a big collection of images that I didn’t use in the end and don’t need 
in the repo.

[NTG-context] request for talk/article on writing modules

[Henning Hraban Ramm]

Hi wizards,
I’d really appreciate an introduction “how to write a ConTeXt module” at 
the meeting and in the next journal.


* How does this namespace and setup stuff work?
* When does it make sense to use variables, macros or parameters?
* Should I use the namespace for internally used MP graphics, 
environments, buffers etc.?


I guess I can figure out most of it on my own, but I think we should 
have some easily understandable documentation.


Or do we already have something and I didn’t find it?

I can contribute the part about distribution.

Best, Hraban

[NTG-context] expansion and variables

[Henning Hraban Ramm]

Something’s wrong with my code.
I’ll try to keep a status to output a certain marker only the first time 
after a change. With the code below I get it never.


I guess it’s an expansion problem again, but I didn’t find the right 
places for \expanded – if I use it in front of every \getvariable, I get 
the output every time.


Please help…

weeks (until end of July)!


I would appreciate the help of English native speakers for

Table floats split in odd places, independent of top/page/here location.

There’s always a first part, then some not-float text, then the other

Even if the table would fit on two pages (with location=page), it always 
gets split into three.


Can I influence this anyhow?


Hans explained in today’s online meeting:

The float location "split" cannot be combined with other locations

[NTG-context] Re: index sort order (de)

[Henning Hraban Ramm]

Would any of the German users object to a change of the default?

Am 14.05.24 um 18:57 schrieb 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 I’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).
