Re: [NTG-context] Using ConTeXt-LMTX for modern Mathematically-Literate-Programming 2/2
Hans, If my only constraints were ease of programming and moderate performance, I would completely agree that using mostly Lua plus (possibly) some C code for some targeted stuff that is really slow in Lua is the correct solution we are actually in agreement. Unfortunately, I have the *non-functional* requirement to *prove* the code's correctness this is the heart of what I have to write about. There is no getting out of this requirement So, some day it would be very useful to be able to directly embed a Lua wrapped ANSI-C shared library inside the new LuaMetaTex However, at the moment, as part of my parallelization attempts I can interact with my ANSI-C code over a network so I will use this approach for the near to medium time frames.

Re: [NTG-context] Using ConTeXt-LMTX for modern Mathematically-Literate-Programming 1/2
Hans,
Many thanks for your swift and helpful comments.
After some *very crude* tests using the `luametatex` and `luametafun`
documents, I find that while I *can* stop effective processing at
various points in the LuaMetaTeX pipeline, the time difference overall
is not really significant enough to bother with this approach.
The principle problem is, as you suggested below, "stopping" the
pipeline at the PDF stage (using for example the `pre_output_filter`)
corrupted the `*.tuc` data which is for my purposes, critical.
Your comment was:
> but keep in mind that multipass data is flushed as part of the
> shipout (because it is often location and order bound)
For the record, using the `append_to_vlist_filter` callback, I did
manage to drastically reduce the "pages" (which were all blank, not
surprisingly).
However, on my elderly desktop from 2008, both callbacks essentially cut
only 6-8 seconds out of 18 seconds, for the `luametatex` document, and
190 seconds, for the `luametafun` document.
In the case of the `luametafun` document, it is the MetaFun/MetaPost
processing which, of course, is taking a long time (as it should, the
graphics computations represent important but complex computations).
My ultimate goal is to parallelize the production of large, heavily
cross-referenced, ConTeXt documents... more on this in a future email...
Again, many thanks for your comments!
Regards,
Stephen Gaito

I have used figure libraries in the mkII past. But my recent attempts with mkIV, following the instructions on ConTeXt Wiki (https://wiki.contextgarden.net/Image_Database), have failed. The following happens: 1. When running the command "context --input=figure-lib.xml auto:x-res-01.mkiv --result=figure-lib" in an EMPTY directory, 2 pages with buttons and titles are created. 2. When providing an image and an xml file (copied from the website above and including the image name and the missing ">" at the end), these are ignored -- the same 2 empty pages are created.

should behave as usual and are numbered by text.

In the MWE, the footnotes just disappear. In the actual project the problem is
different, but I couldn’t reproduce it in a MWE. I guess the interference of
different note types is the cause of both problems.
I tried using the same custom note for the last comment as a workaround, but it
gets placed twice: once at the bottom of the current page (i.e. like a normal
footnote, out of order) and once after the other custom notes.
(The letter is in a delimitedtext environment.)

Re: [NTG-context] numbering pages included by \copypages
After further testing guided by Hans’ suggestion, I now have
\setupexternalfigures[location=default]
\setuplayer[preset=rightbottom, method=overlay]{}
\setuppagenumbering[color=darkmagenta]
\starttext
\getfiguredimensions[HannahBW.pdf]
\dorecurse{\noffigurepages}{
\startTEXpage[pagestate=start]
\layeredtext[]
[boffset=3pc, roffset=3pc]
{\darkmagenta\subpagenumber}
{\externalfigure[HannahBW.pdf][page=#1]}
\stopTEXpage
}
\stoptext
which works, though it would arguably be better if there is a way to
prevent the subpage number on the first page of every included file.

Re: [NTG-context] odd behaviour with \definefontfamily
I intend to use it! So, yes, I had not used it at this point, and your explanation now makes sense. In the test example I have, I have now placed a line: \ss My text, and I see that it now loads the sans serif font. But can you explain why it loads the math font, given that I have not, as yet, used that anywhere (and may not - it is there for insurance in case such a glyph is needed)?

Re: [NTG-context] compilation error in LMTX
Hello Lutz, I can confirm this.

Yes, commenting things out in my own tex-documents might result in a successful compilation, but I had a document (which compiles normaly now, but not two days before) where I got the same error at another position in the file (after deleting all chapters after the one where the error occurred including the one with the error).

Re: [NTG-context] margin notes (was: lmtx update)
Hi Hraban,
Thanks for the hint… indeed I did see that \ColWidth command but didn't think
about its definition… Sorry!
Now with \ColWidth defined, your code works fine and it has the advantage that
the text of the sidenote begins in the margin at the level where the \footnote
command appears. However, it cannot control the overflow of a sidenote to the
next page, whereas the code given by Hans can do that. I admit that this does
not happen very often since a well designed text should not have too many long
sidenotes…
In case other users would like to use your code, I put the whole example below.
Best regards: Otared

Re: [NTG-context] spacing before items
Mike Cooper writes: Thanks David! I don't think I've ever been quite so frustrated at trying to learn anything else in my life! If it wasn't required by my job, I wouldn't have made it past the first day or two (3 months ago). But I'm slogging away and it's gradually coming together (I think). I spent my whole day yesterday figuring out how to do some very basic formatting/layout that would have taken 5-10 minutes in Word or HTML/CSS. People have been very helpful and patient with me!! Thanks to all of you for that! And thanks David for this explanation of the situation. regards, Mike You may already be doing what I'm about to suggest. If so, please disregard. One source that has helped me a lot is the archive of this mailing list, where I've searched for any messages that mention whatever it is that I'm looking for. Of course such a search is slower than scrolling through the index of a manual, and sometimes it's hard to figure out "What keyword do I search on? If I knew the correct keyword, I'd be done this already!" - but quite often I've "hit the jackpot" and found exactly what I needed, or close enough that I only had to change some details. You will soon notice that there are some people on the list who consistently see through the problems that are presented, and who say something like "I think you probably want something like this:" - followed by a solution that makes you say confidently "A-ha! So THAT'S how that's done!". The really good problem-solving sessions on the list, both the elegant answers and the questions that precede them, could form a pretty good start on a manual. Of course such a method is hit-or-miss, but in this case there are quite a few hits. Just watch out (in much older messages) that you're not fully relying on an answer based on ConTeXt Mk II, because many of those solutions no longer work in the newer versions. ... which has accidentally led me to another documentation comment. Hans's programming philosophy is not something I'm an expert on, but it seems clear that he values "usability, good function, and getting the job done well" much higher than he values "backward compatibility forever". In other words, if something is broken or not good enough, he doesn't hesitate to fix it or improve it in the best way he can see. This is good for the software in that it is constantly improving in every direction, but it does also make it a bit more of a challenge to document, and a bit more of a challenge to find someone who *wants* to document it - "How ConTeXt Used To Work Last Year" is clearly not going to be a top-selling title. :) But despite that, the majority of what you want to know has not changed in quite some time, and usually only *very* old solutions will fail completely. I want to finish this message by saying: When you read through "SomeFile.tex" that you've created, every switch and command in it should make sense to you. In the beginning that might not always be the case, but it's easier for you to get there than it might sound, and you'll see that all the best solutions you get from others share that quality of "Ah, I see, that makes sense, I get how this works". Most of the time, a solution that doesn't give you that feeling is not quite the right way to do it. Of course a poor solution is better than nothing, but please don't stay satisfied with hairy-looking clusters of commands that sort of work but no one knows why. (I've written lots of those, that's why I say this.) :) Simple and direct writing means the mistakes will soon become obvious; the worst thing to do in ConTeXt is to make a complicated mysterious mistake that you can't even find. Well. THAT turned out longer than I intended. :) -- David ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://context.aanhet.net archive : https://bitbucket.org/phg/context-mirror/commits/ wiki : http://contextgarden.net ___

This make sense. Messing code to force ConTeXt to work as it isn’t

Pablo, do I understand right that you’re converting XML and the comment comes
last in that structure, but you need it first?
I.e. the real question is how to process the XML structure in a different
order, right?
That would avoid shifting boxes around, which might be possible, but ugly and
hard to control.

There is no bug. When you take a look at my pagenumber example you see a
few lines at the top show the number of the previous page, this happens
because TeX collects more than necessary which means in your example
above the layer is placed when TeX was still on the first page.
Many thanks for your reply, Wolfgang.
I’m afraid that TeX is too tricky for me in that case (or I simply think
that it is misbehaving there).
In your example you can add \testpage to \section to force a page break
when there isn't enough space available to place the heading, this moves
also the layer placement to the next page.
I’m afraid this doesn’t work with my real document.
I need another approach. This sample reflects my problem:
\setupinteraction[state=start]
%~ \showframe\showgrid
\starttext
\dorecurse{41}{one line\par}
\ \comment[location={rightmargin}]{comment}
\stoptext
Since layers are problematic for the task, I insert the comments right
after the text (which actually comes from \xmlflush{#1} [XML sources]).
I’m afraid that the paragraph before \comment comes from \xmlflush, so I
cannot avoid it.
This is unproblematic for most cases, but the sample above displays the
problem of adding a comment in a new paragraph. It might add a new page.
To avoid this issue: how could I prevent the pagebreak before \comment
and the addition of a pagebreak above?
If that were possible, I could add a \blank[-2*line] that would place
the comment right.
Try
\removeunwantedwhitespace
or
\blank[samepage]

Re: [NTG-context] Filter module for R

Hi,
Following a question about the broken R module (R the statistical
software), Aditya suggested me the filter module (thanks to him). I’m about
to distribute a set of course notes to colleagues, and I need to deal with
details now. I have one problem and two questions.
1) the filter collect R code between \startR / \stopR and submit this code
to R. As it can be seen in the following minimal example, when a label
contains an accented character (« Fréquence » in my example), the pdf
graphic does not contains the « é ». Strangely, the snippet of code (which
is saved locally as « test2-temp-R-0.tmp » (for test2.tex)) when submitted
with the same command as the filtercommand, works correctly; that means the
same file works when submitted to R outside of ConTeXt. I have no idea how
to solve this.
Are you running the exact same command as the `filtercommand`. If so, I don't
know why running the `filtercommand` through context vs directly typing it on
the terminal should behave differently. The filter module effectively just
runs os.execute("filtercommand"). I don't use R so I am unable to debug
further.
I can reproduce this output side the filter module. If I directly run os.execute(...)
from a lua session, the output is correct but running it through context gives the wrong
output. I am guessing this is something to do with locale. I notice that the output of
os.execute("locale") from context is different from that from my shell. But I
don't know why locale should affect UTF characters in R. Perhaps someone with more
knowledge of R can comment on that.

[NTG-context] using annotations for extended print handling
Dear list,
I have an over a thousand pages document generated with ConTeXt.
I need to print and chapters and part of chapters (or send to other people).
/PrintPageRange is great (and you can even generate a new document
containing only the pages in /PrintPageRange). But the issue here is
that I would need to recompile the document again for each new required
/PrintPageRange.
Another approach would be to add PDF annotations (outside page
boundaries) to store the desired information.
So I created text annotations (using \comment) with author information
composed from unit number (such as "i3", "ii9" or "iii28"), info on the
unit part (such as "-explanation", "-synopsis", "-exercises", or others)
and position ("-start" and "-stop").
This would make author fields such as "i3-start" (which has a
corresponding "i3-stop", or "ii22-synopsis-start" (with the
corresponding closing annotation).
To make easier to identify these annotations, they all share the same
title. As contents, all these text annotations have the page number.
From the generated PDF document, I need to read all text annotations in
order to extract two fields from those annotations that contain a
"whatever" /Subj. These fields are /T and /Contents.
I guess that the way to deal with the (over 700) annotations would be to
store both fields in a Lua table. But this is only a suspicion, since I
don’t know how to read the values, how to store them, or how to compare
them with specific units or unit parts to get these page numbers.
I mean, with a command such as
\extractpages{i5,i8-exercises,i15-explanation} would get the pages for
each "-start" and "-stop" that could be passed automatically to a
\filterpages command.
A sample that generates something similar:
\setuppapersize[A8]
\setupinteraction[state=start]
\starttext
\dorecurse{5}{\part{\romannumerals{\recurselevel}}
\dorecurse{15}{\chapter{\recurselevel}
\comment
[title=whatever,
color=yellow,
%~ the following code is to have expansion in interaction
author={\ctxlua{context([[\namedstructurevariable{part}{title}%
\namedstructurevariable{chapter}{title}]].."-start")}}]
{\pagenumber}
\doloopoverlist{explanation,exercises,synopsis}{\chapter{\recurselevel}
%~ I would like to use \recursestring, but it is undefined here
\comment
[title=whatever,
color=green,
author={\ctxlua{context([[\namedstructurevariable{part}{title}%
\namedstructurevariable{chapter}{title}]]..
[[-\recurselevel]].."-start")}}]
{\pagenumber}
\dorecurse{5}{\null\page}
\comment
[title=whatever,
color=blue,
author={\ctxlua{context([[\namedstructurevariable{part}{title}%
\namedstructurevariable{chapter}{title}]]..
[[-\recurselevel]].."-stop")}}]
{\pagenumber}
}
\comment
[title=whatever,
color=red,
author={\ctxlua{context([[\namedstructurevariable{part}{title}%
\namedstructurevariable{chapter}{title}]].."-stop")}}]
{\pagenumber}
}
}
\stoptext
Is there a way to deal with the annotations in the document generated
from the code above, in the way I described before?
Many thanks for your help,
Pablo

Re: [NTG-context] using modeset
I tried this too, a number of times. For lengthy texts it makes little sense.
One important thing is that, as BPJ says, you loose the flow during writing.
When the document is finished, it is difficult to get an overview.
If you consider it using for lengthy documents, I would consider to set up an
xml file. You can then have the overview via scripts.
Yet for short texts it can be a solution. I have case material for my trainings
in both English and Dutch in the same file. Instead of modes, I use blocks.
Like this:
\defineblock[ENblok]
\defineblock[NLblok]
\setupblock[NLblok][before={\mainlanguage[nl]},after=]
\setupblock[ENblok][before={\mainlanguage[en]},after=]
Then, determine which blocks you want to use in your file:
\hideblocks[NLblok]
%\hideblocks[ENblok]
For the titles I use another method:
%\def\NL#1{#1}
\def\NL#1{{}}
%\def\EN#1{}
\def\EN#1{#1}
You have to comment and uncomment, depending on the language, but I think you
can put them in the NLblok or ENbloks instead.
\definecomplexenumeration[Casus]
… definition
\def\refno#1{{\em{(no. \small #1})}}
My files look like this:
\starttext
\startCasus[casus-349][\NL{Een moeilijke zaak}\EN{A complicated case}]
\refno{casus-349}\crlf
The casus-349 element is used as a label. After the text I have a list of
questions for this case in a separate block for questions, introduced by
\in[casus-349]).
You can probably also use something like
\section[\NL{Een moeilijke zaak}\EN{A complicated case}]{}
\begin[NLblok]
\startlinenumbering
text ...
\stoplinenumbering
\end[NLblok]
\begin[Enblok]
\startlinenumbering
text...
\stoplinenumbering
\end[Enblok]
\stoptext
I hope this helps finding a solution.

You are right of course... In fact I already use blocks, for another purpose,
but I did not think about this solution because I needed a lot of formatting
(these blocks should occupy whole page, different background color…), but
blocks can adapt to my current need (I have try this morning) using the
\setupblock[][before=..,after=…] command. And there is a bonus; I can « collect
» these blocks and put them all together at the end of my courses notes, this
is perfect.

[NTG-context] ConTeXt source browser website update
Hi all,
I just replaced the software of https://source.contextgarden.net/ by a Lua
implementation that uses Hans Hagen’s SciTE lexers for syntax highlighting and
a Lua-generated search index.
There is no official documentation yet (because I may want to change some stuff
still) but here is some relevant information:
* The search field uses a Lua string pattern to match a single word (no
multi-word search as of yet).
See https://www.lua.org/manual/5.3/manual.html#6.4.1 for the syntax of lua
string patterns.
* The search index only contains 7-bit ASCII ‘words’ that contain at least one
of 'a-zA-Z’ (writing an LPEG for unicode matching is a tricky and probably
would be quite slow even if I could make it work).
Still, this should be ok-ish because most of the ConTeXt source is ASCII,
except for the interface files.
* The files context-en.xml, mtxrun{.lua}, and all of the files in the
tex/context/patterns subtree are skipped in the search index. Also skipped are
words shorter than 3 bytes, lua keywords, and words having more than (approx)
1500 hits
* On the plus side, because of the SciTE lexer, “contextversion’ and
“\contextversion” are separate entries in the search index. And you can search
for “\@@kldirection”.
* For text file types that have no SciTE lexer there is no syntax highlighting,
and binary files are ignored altogether.
The rest of the interface should be self-explanatory.
Suggestions for improvements are welcome.
Index statistics:
4085 files processed, 178 skipped, 3744 with matches
120733 words found
119154 words exported to word.idx
37928 comment words found
36880 words exported to comment.idx
26756 documentation words found
26018 words exported to docs.idx
The word.idx is roughly 11 megabytes.
Have fun,
Taco

So, if you are willing to define wrappers for all ruby syntax blocks,
then I can provide a configuration option so that `2context` does not
apply that line.
That might provide a finer control over the highlighting, but the main
issue here seems to be that the generated file has Identifier instead of
Function, Special instead of Delimiter and Constant instead of String.
Looking at 2context.vim, AFAICS s:id_name seems computed correctly.
Maybe, the script does not set the appropriate filetype?
filetype is set correctly (since we get `ruby` options), but something
weird is happening even with 2html.vim. Here is a minimal example:
Figured out what is happening. From `:he syntax`
"The names marked with * are the preferred groups; the others are minor groups.
For the preferred groups, the "syntax.vim" file contains default highlighting.
The minor groups are linked to the preferred groups, so they get the same
highlighting. You can override these defaults by using ":highlight" commands
after sourcing the "syntax.vim" file."
All three `Function`, `Delimiter` and `String` are minor groups, so they get
mapped to the preferred groups, which are `Identifier`, `Special`, and
`Constant`, respectively. Most colorschemes define colors for minor groups as
well, but since we are not loading any colorscheme, the minor groups are mapped
to preferred groups, and we only get the preferred groups in the output.
Now that I know what is happening, it is relatively easy to fix.
```
\definecolor[colorone][r=0.251, g=0.349, b=0.322]
\definecolor[colortwo][r=0.612, g=0.608, b=0.478]
\definecolor[colorthree] [r=1.0, g=0.827, b=0.576]
\definecolor[colorfour] [r=1.0, g=0.592, b=0.310]
\definecolor[colorfive] [r=0.960, g=0.310, b=0.161]
\definecolor[nearlywhite] [r=0.988, g=0.988, b=0.988]
\setupinteraction[state=start]
\setupcolors[textcolor=colorone]
\setupbackgrounds[page][background=color,backgroundcolor=nearlywhite]
\usemodule[vim]
\startvimrc[name=minor-groups]
hi Function cterm=NONE
hi Stringcterm=NONE
hi Delimiter cterm=NONE
\stopvimrc
\startcolorscheme[oceansunset]
\definesyntaxgroup[Comment] [color={colorfive},style=italic]
\definesyntaxgroup[Function][color={colorfive},style=italic]
\stopcolorscheme
\definevimtyping[RUBY]
[
syntax=ruby,
alternative=oceansunset,
escape=on, %NOTE, the comma was missing in your test file
% Without the comma, the option is not set
extras=minor-groups,
]
\starttext
\startRUBY
# Ruby program listing
def foobar
print("Hello World")
end
\stopRUBY
\stoptext
```
Since I already map the minor groups to preferred groups in `t-vim`, I think
that a good compromise is to enable the minor groups by default. I can do that
by adding statements similar to those above in `2context.vim`. This will not
have any visual impact on any existing code, but will allow those who want to
tweak the highlighting of minor groups to define their own syntax highlighting.

gives
```test.rb.html
http://www.w3.org/TR/html4/strict.dtd;>
...
# Ruby program listing
def foobar
print(Hello World)
end
```
which is similar to what 2context.vim gets. If I source tohtml.vim or
2context.vim from an existing vim session, then the tags are correct. I have
not been able to figure out why this is happening.

Quick question: Is \startcolorscheme... \stopcolorscheme (still)
supported by t-vim?
It is supposed to work. If it doesn't, then it is a bug. Could you
provide a complete MWE.
Please find a MWE at the bottom of this post.
The expected behaviour is that the keyword `function` in the JavaScript
snippet and `foobar` in the Ruby snippet should be colored and in
italics, as comments are. The respective Vim highlight groups are
`javaScriptFunction` and `rubyMethodName`, which both resolve to
`Function`.
The reason that there is no highlighting is because the generated `.vimout`
does not contain any `\SYN[rubyMethodName]` or `\SYN[javaScriptFunction]` for
the following reason:
Vim has the concept of a hierarchy of names for the syntax highlighting
regions. For example, $VIMRUNTIME/syntax/ruby.rb contains the following
lines:
hi def link rubyMethodName rubyFunction
hi def link rubyFunction Function
So, `rubyMethodName` maps to `rubyFunction`, which in turn maps to
`Function`. Now, a vim colorscheme first checks if a highlighting style is
available for `rubyMethodName`; if not it tries `rubyFunction`; and if not it
tries `Function`.
Although something similar might have been possible in 2context.vim, I follow
the `TOHtml` function of vim, and simply created a single tag for each syntax
highlighting element, which in this case is `Function`. So, there is no tag
generated for `rubyMethodName` and that is why changing the syntaxhighlight
for that doesn't change anything.
Moreover, if you comment line line 126 of `2context.vim`
"let s:id = synIDtrans (s:id)
[If you make a local copy of 2context.vim, then you need to run the file with
`--mode=dev-vim` to ensure that the local copy is used]
Then the ruby example generates the following file:
\SYNBOL{}\SYN[rubyComment]{# Ruby program listing}\SYNEOL{}
\SYNBOL{}\SYN[rubyDefine]{def}\SYN[rubyMethodBlock]{
}\SYN[rubyMethodName]{foobar}\SYNEOL{}
\SYNBOL{}\SYN[rubyMethodBlock]{
print(}\SYN[rubyStringDelimiter]{"}\SYN[rubyString]{Hello
World}\SYN[rubyStringDelimiter]{"}\SYN[rubyMethodBlock]{)}\SYNEOL{}
\SYNBOL{}\SYN[rubyDefine]{end}\SYNEOL{}
So, if you are willing to define wrappers for all ruby syntax blocks, then I
can provide a configuration option so that `2context` does not apply that line.

[NTG-context] Arithmetic Overflow error in MetaFun
Colleagues I'm having problems with an Arithmetic Overflow error when calculating the x and y values for functions of the form: y = ax^4 + bx^3 + cx^2 + dx + e to which I then add a bit of randomness and other embellishments. I have had a look in the Metafun and Metafont manuals but nothing jumps out at me. In the minimum working example below, this Arithmetic Overflow occurs when xord =13.5 but I can get the calculation to work if I separate out the equation and then add together, since it seems to be failing on the pow(xord,4) instruction. Is there a switch in MetaFont that should be set or a better way of getting round this Arithmetic Overflow error?

Please find a MWE at the bottom of this post.
The expected behaviour is that the keyword `function` in the JavaScript
snippet and `foobar` in the Ruby snippet should be colored and in
italics, as comments are. The respective Vim highlight groups are
`javaScriptFunction` and `rubyMethodName`, which both resolve to
`Function`.
The actual behaviour is that comments are highlighted correctly, but
I do not get any syntax highlighting for functions.
Thanks for t-vim, btw: I can't express in words how nice an idea it is!

Should be \placebookmarks[chapter,section]. Move it in front of \starttext.
But that still doesn’t set chapter bookmarks - strange.

I don’t know how to use typescripts and the approach I suggested is the
only one I know to deal with fonts in ConTeXt.
\definefontfamily (and \definefallbackfamily) were created to avoid
using typescripts in the vast majority of cases.

They are just an option. The tilde (~) is added after the percent sign
(%), because “Geany” (the text editor I use) adds it after the comment
sign in different programming languages. It has no special meaning.

Now I get it: a fallback typeface for Russian and the main typeface as
Optima.
This might read the following way:
\setuplanguage[en][patterns={en, ru}]
\definefallbackfamily
[mainface]
[rm]
[Helvetica]
[preset=range:cyrillic,
force=yes,
rscale=0.9]
\definefontfamily [mainface] [rm] [Optima]
\setupbodyfont[mainface]
The first command loads both English and Russian hyphenation patterns in
English, so that you don’t have to bother to mark the texts that use the
Cyrillic alphabet (although all hyphenation of Cyrillic will be
according the Russian rules).
The second command defines the fallback family. It has four option groups.
1. The first group sets up the name to be used in ConTeXt (mainly in
\setupbodyfont and \switchtobodyfont).
2. The second group specifies which kind of typeface is: serif,
sans-serif, typewriter, math and others. Of course, this isn’t a
declaration of what kind of font the selected one is, but how ConTeXt
will handle it. So, if your document is sans-serif only, it is safe to
use "[rm]" with sans-serif fonts as above.
3. The third group specifies the font name as specified in your OS. This
selects it.
4. The fourth group specifies different options. Here for the fallback
font, I specify:
a. Range: for which Unicode blocks (alphabets) will the font be used.
You can use "range=cyrillic", but it is safer to use
"preset=range:cyrillic" (this avoids specifying
"range={cyrillicextendeda, cyrillicextendedb,
cyrillicsupplement}").
b. Force: it is important to set it up to "yes", since otherwise if the
main font (Optima in this case) has any glyph for the Cyrillic block, it
would use that glyph in Optima, mixing it with the other ones from the
fallback font. In my personal experience, this looks crappy.
c. Relative scale to the main font: increase or decrease the fallback
font to match similar x-height with the main font. In this case,
Helvetica has a higher x-height that Optima, so I decreased it.
All the previous options where related to \definefallbackfamily.
\definefontfamily has also three option groups, which are the same that
the ones explained for \definefallbackfamily.
The values for the first and second groups should be the same, values
for the third group should differ. Otherwise, glyph substition won’t
take place (either the font family or typeface won’t match, or the
fallback font won’t be actually a different one).
> I still am totally in the dark how this works and what made the
> earlier setup find Optima but not find Helvetica.
I hope it is clear now: the fallback mechanism for your setup should
read different than the one I provided.
I think it could be better for you to use \definefallbackfamily and
\definefontfamily. It is way simpler.
> And I’m curious why this adaptation doesn’t work:

>[abc]
>[ss]
>[dejavu]
As explained above, the third option group should contain the font name
(as your OS would display it, not as ConTeXt names it [probably, in a
typescript]). So, the value should read "[DejaVu Sans]".
> Anyway, I can go on, not wiser but helped further. Thanks again.
Please, ask what you don’t understand. And if you need help with your
font code, post it on the list and we may help you.
Sorry if the message contains errors (it’s too late for me to write on

Re: [NTG-context] \definehead behaving differently when in an environment file versus \input'ed
n...@scorecrow.com schrieb am 02.05.2020 um 17:14:
I'm having trouble with \definehead behaving differently depending upon whether
I process a file that includes it via a \input statement versus a project
structure that calls it via an environment file referenced from a component
file.
Overall aim:
I currently produce a small circulation journal in Word that I'm hoping to
switch to ConTeXt. Each article is written by a different author and I
currently provide a Word template so they can see how their article will
eventually look and how long it is, etc. I want to do the same for the ConTeXt
version so I have created a template tex file they can simply \input at the top
of their article. Processing the single article gives the desired output. So
far so good.
When I receive the articles, I want to use the project/product/component
structure to allow me to produce an entire issue of the journal in one go. (I
would simply comment out the \input line and add \startproject \startcomponent
etc lines as necessary from each received article.)
Problem:
I've created a custom chapter heading, but the font size changes depending on
whether I'm processing the \input version of the article or the \component
version and I don't know why. Obviously, I would like the heading to be the
same in each case so that authors see what I see and vice versa.
Your simple version sets the bodyfont before \starttext
begin example
\setupbodyfont[termes,14pt]
\starttext
{\bfc Cheesy double boxed title}
\stoptext
end example
while your complexer version loads the bodyfont after \starttext
(\startcomponent acts here as \starttext)
begin example
\starttext
\setupbodyfont[termes,14pt]
{\bfc Cheesy double boxed title}
\stoptext
end example
When you use a non standard font size (e.g. 14pt) size switches are
sometimes ignored even with ConTeXt's fallback mechanism.
To get the correct size for the header you can either use a standard
font size (14.4pt) or you add the following line before you set the
global font for your document (ConTeXt does this by itself in most cases
but it can fail).
\definebodyfontenvironment [14pt]
I attached a slightly modified version of your project structure to show
a different way to organize documents. What I would change is to use a
better section name for each article, e.g. \Article (or \startArticle)
is better than \MyTitle as first level header in each article.

[NTG-context] \definehead behaving differently when in an environment file versus \input'ed
I'm having trouble with \definehead behaving differently depending upon whether I process a file that includes it via a \input statement versus a project structure that calls it via an environment file referenced from a component file. Overall aim: I currently produce a small circulation journal in Word that I'm hoping to switch to ConTeXt. Each article is written by a different author and I currently provide a Word template so they can see how their article will eventually look and how long it is, etc. I want to do the same for the ConTeXt version so I have created a template tex file they can simply \input at the top of their article. Processing the single article gives the desired output. So far so good. When I receive the articles, I want to use the project/product/component structure to allow me to produce an entire issue of the journal in one go. (I would simply comment out the \input line and add \startproject \startcomponent etc lines as necessary from each received article.) Problem: I've created a custom chapter heading, but the font size changes depending on whether I'm processing the \input version of the article or the \component version and I don't know why. Obviously, I would like the heading to be the same in each case so that authors see what I see and vice versa. I've attached a small zip file with a directory structure containing a minimal example. There are two directories: "input_version" and "project" version and the article.pdf files in each show the difference in the heading. I'm using TeX Live 2020 on a Mac. The console reports: ConTeXt ver: 2020.03.10 14:44 MKIV beta fmt: 2020.4.18 int: english/english -- Bruce Horrocks Hampshire, UK ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://context.aanhet.net archive : https://bitbucket.org/phg/context-mirror/commits/ wiki : http://contextgarden.net ___

Processing single components won’t work in your project, since I defined
several metadata macros in the product. More off list.

Comment lines are not handled by TeX, and therefore don’t get expanded.

Re: [NTG-context] Right-to-left pagecolumns and markings in ConTeXt
If I change the line containing that in my MWE to
\setupheadertexts[top: {\getmarking[TestMark][column:top]}][bottom:
{\getmarking[TestMark][column:bottom]}][top:
{\getmarking[TestMark][column:top]}][bottom:
{\getmarking[TestMark][column:bottom]}]
or
\setupheadertexts[top: {\fetchmark[TestMark][column:top]}][bottom:
{\fetchmark[TestMark][column:bottom]}][top:
{\fetchmark[TestMark][column:top]}][bottom:
{\fetchmark[TestMark][column:bottom]}]
then the problem is not fixed. Is this what you had in mind, or were you
suggesting to use it in conjunction with the column number as a second
argument? In that case, the line would look like
\setupheadertexts[top: {\getmarking[TestMark][1][column:top]}][bottom:
{\getmarking[TestMark][2][column:bottom]}][top:
{\getmarking[TestMark][1][column:top]}][bottom:
{\getmarking[TestMark][2][column:bottom]}]
If I use that line, then I do get markings from the first column (i.e., the
right column in this case), but they don't seem to be correct; marking 1
isn't referenced in the header of the first page, and the first new mark on
the second page is treated as the top mark for that page, rather than the
current mark at the time the second page begins (which may be correct, but
still does not seem consistent with the behavior on the first page). If
this is the correct behavior, then is there something I should change in my
syntax to make marking "1" appear as the top mark for that page?

[NTG-context] Right-to-left pagecolumns and markings in ConTeXt
I am trying to typeset a two-column text in a right-to-left language using
ConTeXt. Because I want footnotes in this text to be set ragged-bottom, I
am using pagecolumns instead of standard columns. I also want to track the
first and last textual division markers on each page using markings.
Combining all of these ingredients seems to create a problem in ConTeXt:
when the pagecolumns are set in right-to-left order, the top and bottom
marks fetched are always the top and bottom marks in the left column, while
the true top mark should be the top mark of the right column. I've observed
this behavior using text in an actual right-to-left language, but the
following minimal (non-)working example with an English sample text
demonstrates the same behavior:
```
%Create a new markset to use:
\definemarking[TestMark]
%Setup header to reflect top and bottom marks:
\setupheadertexts[top: {\fetchmark[TestMark][top]}][bottom:
{\fetchmark[TestMark][bottom]}][top: {\fetchmark[TestMark][top]}][bottom:
{\fetchmark[TestMark][bottom]}] %even left, even right, odd left, odd right
%Setup the columns layout:
\definepagecolumns [example] [
n=2, %number of columns
direction=reverse, %does not work if ending comma is removed!
]
\starttext
\startpagecolumns[example]
\marking[TestMark]{1}(1) \input knuth\par
\marking[TestMark]{2}(2) \input knuth\par
\marking[TestMark]{3}(3) \input knuth\par

\marking[TestMark]{7}(7) \input knuth\par
\marking[TestMark]{8}(8) \input knuth\par
\stoppagecolumns
\stoptext
```
I typeset this using ConTeXt version 2020.03.10, as released with TeXLive
2020. As my comment in the MWE points out, there also seems to be a bug in
the key-value parsing of \definepagecolumns that causes it not to parse the
direction=reverse input unless it is followed by a comma.
Is there some way I can improve my syntax to avoid this issue, or is it
just a bug that needs to be fixed? I've tried fetching other marks (e.g.,

There is so much in it that suits to my needs that I have to read it carefully later. But I have some short remarks anyway. Some topics are especially of interest to me: 1. Nameing and organizing the project, product and environments files. I am currently reorganising the files for my cooperative. I think that besides some nameing conventions it is more or less up to me how I organise our print work. Any recommendations welcome. 2. The "Deutsches Text Archiv" has prepared a text corpus of German texts up to 1900 in TEI PS XML, so we could use them directly to typeset books. What I am looking for is a script to extract all XML tags/tokens from their files to have a complete list of things that should be handled in a ConTeXt style file. Five years ago I tried to create such a style file by hand, but I gave up. https://github.com/juh2/tei-style-dta-context The tokens/tags differ from text to text and I think the structure too so that it was beyond my knowledge to generate a general style file for all texts. 3. Being a writer I think that Markdown --> ConTeXt is the best way to achieve what I want: easy writing and professional looking books. Up to now I used Pablos way via pandoc and XHTML described here: http://www.from-pandoc-to-context.tk/ The problem with pandoc is that it does not generate a perfect ConTeXt source to build the file as some things are missing. Annotations and eg. your classify.lua might be a second approach to achieve what I want. So thanks a lot for your work. @all: Feel free to comment on my three topics any hints are welcome.

bug. Here’s a new example:
#
# \setbreakpoints [compound]
#
# \definelinenumbering

# \stoptext
#
# If you compile it, you will see that the “color” key of the two defined
linenumbering environments is not followed. If you comment out the first line

Thank you for the hint - we’re still waiting for an answer to Wolfgang’s bonus
question. But I have continued testing and discovered what is certainly a bug.
Here’s a new example:
\setbreakpoints [compound]
\definelinenumbering
[original]
[style=\tx\ss,distance=-1ex,step=5,location=inleft,start=10,color=darkred]
\definelinenumbering
[translation]
[style=\tx\ss,distance=-1ex,step=5,location=inleft,start=50,color=darkblue]
\starttext
\framed
[background=color,
backgroundcolor=gray,
align={normal},
frame=off,
loffset=6ex,
width=\textwidth,
foregroundstyle=\ss]
{\startlinenumbering[original]
\input knuth
\stoplinenumbering
\blank [line]
\startlinenumbering[translation]
\input klein
\stoplinenumbering}
\stoptext
If you compile it, you will see that the “color” key of the two defined
linenumbering environments is not followed. If you comment out the first line
\setbreakpoints [compound], you will get two colors, as expected. I leave it as
an exercise for Hans and Wolfgang to explain what’s going on here :-)

Henri,
This looks very promising. It works, mostly. That is, all fonts that
use default fontfeatures pick up the change. So, for example, the
companion sansserif for my body font also gets it even though that is
not what I want.
I can remove kerning from the default fontfeatures and add it back
just for the problematic font, but that means no kerning for the sans
font.
Is there a way to apply this to one font only (serif upright, bold,
italic, ...) or even a single face (upright), perhaps by giving it a
unique name? I have tried a few variations but had no success. The
fonts-mkiv manual has very little on this, and the cld manual nothing.
Okay, I have progressed further but have run into something (else) I
cannot understand. Consider the following example:
\definefontfeature [myserif] [mode=node,kern=yes,xkern=yes]
\definefontfeature [mysans] [mode=node,kern=yes,xkern=no]
\definefontfeature [none][mode=node]
\definefontfamily[mykerns] [serif] [Baskervaldx][features=myserif]
\definefontfamily[mykerns] [sans] [Dejavusans] [features=mysans]
\definefontfamily[default] [serif] [Baskervaldx][features=default]
\definefontfamily[default] [sans] [Dejavusans] [features=default]
\definefontfamily[nokerns] [serif] [Baskervaldx][features=none]
\definefontfamily[nokerns] [sans] [Dejavusans] [features=none]
\definefontfamily[legends] [mono] [Dejavusansmono] [features=default]
\startluacode
fonts.handlers.otf.addfeature {
name = "kern",
type = "kern",
data = {
["x"] = { ["x"] = -300 },
[" "] = { ["A"] = 1000 }
}
}
fonts.handlers.otf.addfeature {
name = "xkern",
type = "kern",
data = {
["x"] = { ["x"] = 500 },
[" "] = { ["J"] = 500 }
}
}
\stopluacode
\startbuffer[Sample]
g, Jaxxb AJon
\stopbuffer
\define[2]\Test{
{\switchtobodyfont[#1]#2\getbuffer[Sample]}}
\setupbodyfont[legends]
\starttext
\starttabulate[|l|l|l|]
\NC test \NC Serif\NC Sans \NC \NR
\NC nokerns \NC \Test{nokerns}{\tf} \NC \Test{nokerns}{\ss} \NC \NR
\NC default \NC \Test{default}{\tf} \NC \Test{default}{\ss} \NC \NR
\NC mykerns \NC \Test{mykerns}{\tf} \NC \Test{mykerns}{\ss} \NC \NR
\stoptabulate
\stoptext
It shows, as far as I see, that the kern feature type supports " ", but
only when it is named kern. When it is named xkern, as here, it does not
support spaces, but does support other characters.
If I can get support for a separate feature name, I can easily apply
this corrective kern to the single problematic font.
I also tried a goodie file, but it, too, did not support the " ".

[NTG-context] Indentation problem inside enumeration
Hi!
I've met a strange problem with indentation in consecutive enumerations. It
seems to me that if
1) the first enumeration uses indentnext=no
AND
2) the next enumeration uses a background
then the second(?) paragraph of the second enumeration is not indented.
Here is a small example (see what lines to comment to avoid the problem).
%%%
\defineenumeration[losning][
text=Lösning,
title=yes,
alternative=serried,
width=fit,
number=no,
headstyle={\em},
titlestyle=,
indentnext=no,% another way to get indentation is to comment this line
indenting={yes,medium},
]
\defineframedtext[anmärkningsbakgrunden][
width=\textwidth,
background=color,
backgroundcolor=gray,
]
\defineenumeration[anmarkning][
text=Anmärkning,
title=yes,
headstyle={\definedfont[Bold*default]\WORD},
alternative=serried,
width=fit,
number=no,
prefix=no,
indentnext=no,
indenting={yes,medium},
before={\startanmärkningsbakgrunden},% if these two lines are commented then
after={\stopanmärkningsbakgrunden},% the indentation works
]
\starttext
\startlosning
This environment destroys indentation in the next.
\stoplosning
\startanmarkning
This is just a first paragraph.
This paragraph should be indented.
This paragraph is always indented.
\stopanmarkning
\stoptext

(This is a stripped down example with some settings removed. But it shows
the point.)
Am I doing something wrong? The resulting pdf is attached.

And I remember I was totally shocked when he explained to me that the standard document format for any word processor was OpenOffice.org. Anyone claiming that something is a standard (esp in computer science) is unaware of history. I bet that our ancestors of thousands of years ago also considered themselves modern, with standards etc. But sometimes I think that many folks today think of themselves as being on top of the human (intelligence, progress, morale, etc) pyramid compared to whoever came before. History proved them wrong. (Similar are claims of this or that being better (software, operating systems, etc) while in the end much converges to the same.) Anyway, it's a waste of time and energy discussing with those folks. And we as texies should also be honest: how many of the acclaimed 'happy' tex users are really 'happy' with their system and are those 'millions' really (unforced) users who couldn't as well be using word or google docs or ... given what and how they deal with documents. And let's not add the quality argument because a coupel of weeks ago I noticed how bad tex output didn't look any better in a display of some 80 summaries at some meeting (the, oh, look how bad that table looks experience). (I'm sure Arthur, when reading this, can comment as we sort of had this at a theme of a talk!) (And, yes I consider myself a happy tex user, but I also admit that I don't have to write much. And yes, it's a specific kind of user and usage.) I cannot recall the accurate details from his explanation, but he seemed to think that even Microsoft Word was at fault for not implementing the Open Document Text format (.odt) as its native format. I suppose he read the specs of both formats in detail (in print of course). The reasoning was so bizarre and shocking to me that I understood that it was better to me simply to decline the discussion. Also other factual inaccuracies about the work done in other departments made me clear that it was better to avoid the conversation. Indeed. Waste of time. Just think of this: you could kind of check his claims, so how about all the other claims someone makes ... stuff you know little about ... how valid are those claims then. OOo was the cause of many compatibility issues in that company, because they simply uninstalled Microsoft Office and installed OpenOffice.org (no previous warning) in one evening. Well, as long as they're happy ... in most cases no one cares how output looks, nor cares about long term storage and exchange of data. Going belly up means 'delete all data and thrash the machines'. The installation was so poorly performed that they forgot to assign Microsoft Office extensions to OOo programs in Windows. AOnly this minor incident was a huge problem for the vast majority of users. And then they entered denial state. It was clear to me what I knew decades ago: free software isn’t programs for free. I think they still have to deal with issues in OOo. Although, not all free software comes for free. I'm not that sure of online tex services are cheaper than bulk microsoft licenses. I only talked no more than five times with that guy. But if he was the evangelist of free software in that company, I’m afraid I totally agree with the people working there that hated OOo. It's all about honnesty isn't it? And about people spending time and energy, That doesn't always goes well with commercial objectives. And there's always the knowledge issue. And expecially when open source and such starts looking like a religion (one without a long history of dealing with itself and communicating properly) it gets even trickier.

Think TeX (and a little ConTeXt):
\starttexdefinition thinrulesfillpage

\verticalstrut
\vskip-.5\lineheight
\leaders
\hbox to
\hsize{\blackrule[width=\hsize,height=1pt,depth=1pt,color=red]\strut}

Now Wolfgang can change the \leaders in the proper ConTeXt interface
calls. Okay, we could as well make it into some feature or course, as
occasionally we need to add something new anyway, just to show progress.

Re: [NTG-context] Filling a page with \thinrules
Hi Rik,
Thanks a lot for the link to that message dating back to 2010…
I tried to put that solution on the wiki but I could not create a new page.
I'll try later.
For the record, below is a transcript of what I adapted from Wolfgang's
solution, but maybe nowadays one could also right a more readable lua code to
achieve the same.
Best regards: Otared K.
\define\thinrulesfillpage%
{
\hphantom{Answer} % this is necessary, I don't know why...
\blank
\scratchcounter\dimexpr(\pagegoal-\pagetotal-2\lineheight)/(\dimexpr\lineheight+2.2ex\relax)\relax
\thinrules[n=\number\scratchcounter,inbetween={\blank[2.2ex]}]
\page
}
\showframe
\starttext
\dorecurse{2}{\input knuth.tex\par}
\thinrulesfillpage
\thinrulesfillpage
\input ward.tex
\thinrulesfillpage
\stoptext
