The installer does not work for me.

context % mtxrun --script install-modules
mtx-install-modules | ConTeXt Module Installer 1.00

context % mtxrun --script install-modules --list
mtx-install-modules | loading entries from file 
'/usr/local/texlive/context/tex/texmf-context/tex/context/modules/third/mtx-install-imp-modules.lua‘

Up to here everything is fine.
But when I try to install I get:

context % mtxrun --script install-modules --install --all
mtx-install-modules | unknown subdirectory 'texmf-context‘


I have to
context % cd tex

After that the installer works fine.
 
context % mtxrun --script install-modules --install --all

[NTG-context] ConTeXt meeting and the annotated cow

[Axel Kielhorn via ntg-context]

Hello,

last week I learned something about MetaPost at the context meeting.
Thanks Taco!

First a little background:

I write a lot of documentation and sometimes I need to include a picture with 
annotations.
Until now I used a drawing program to add text and arrows.
This has one disadvantage, these annotations are not translated.
I have to prepare a set of pictures for every language.

Well, that changed last week.
Here is my first try (actually the 4th iteration):

%%%
\setupexternalfigures[location=default]
\starttext

\startMPinclusions
%draft := 0;
draft := 1;

color mycolor;

if draft = 1 :
mycolor := red ;
else:
mycolor := .4white ;
fi ;

% Draw a grid to count locations

def gridscaled =
pair ur;
ur = urcorner currentpicture;

width :=  xpart ur;
height := ypart ur;

xstep := ceiling(width / 10);
ystep := ceiling(height / 10);

if draft = 1:
counter := 1;
for i = xstep step xstep until width :
draw (i, 0 ) -- (i, height);
label.rt(counter, (i , 0.5 cm));
counter := counter + 1 ;
endfor;

counter := 1;
for i = ystep step ystep until height :
draw (0, i) -- (width, i);
label.top(counter, (0.5 cm, i ));
counter := counter + 1 ;
endfor;
fi;
enddef;
% Bottom: The annotation is at the bottom of the start point
  
def annotb (expr a,  b, c, d) (text t) =
label.bot (t, (a * xstep,  b * ystep));
drawarrow (a * xstep, b * ystep) -- ( c * xstep, d * ystep)

withpen pencircle scaled .5mm withcolor mycolor;
enddef ;

annotb (3, -.5, 3.1, .9, "Huf");
annotb (3, -.5, 3.9, 1.1, "");

\stopMPpage

\stoptext

%%%

There are still some further ideas and a lot to learn for me:
- multi line annotations
- a transparent white background
- a frame around the text
- a link to the section where the part is explained 
- moving to one command with the orientation as an argument

Comments and improvements are welcome.

[NTG-context] LMTX and modules

[Axel Kielhorn via ntg-context]

Hello,

Some years ago I wrote an introduction to ConTeXt in German:

https://github.com/AKielhorn/Context-Intro

But that was long ago.

Today LMTX is state of the art and I tried to build it with a recent LMTX.

This lead to problems because LMTX does not include modules.

Therefore my question is:
Is the a plan to include modules into the regular LMTX installation?

If not, is there a way to test for a certain module?

\doiffileexists{m-module}
\usemodule{module}

Greetings
Axel

Of course we do, especially after Hraban recommended the 2021-10-10 tree last 
week.

Just one question:

LMTX comes with an empty texmf-modules tree.
Are we still supposed to copy the context version?

There have been updates to letter, filter and some others lately.
That means we have to update the context tree as well.

Do you plan to include this tree in the future?

Greetings

Axel

PS: I tested one document with the new version without problems.

[NTG-context] \setupinitial: style Parameter resets size

[Axel Kielhorn]

Hi,

since the lettrine module does not work with LMTX, I’ve looked into 
\setupinitial.
(There is a different thread about this.)

There is a „style“ parameter to change the style, but whenever I change the 
style, the font size is reset.
This is not what I expected.

This was the case in context before LMTX, thus it is not a regression.

% !TEX TS-program = ConTeXt (LuaTeX LMTX2021)
% !TEX encoding = UTF-8 Unicode

\starttext

\setupinitial[color=red]

\start
\setupinitial[n=2,m=1]
\placeinitial\input ward
\stop

\start
\setupinitial[style=\tf,n=2,m=1]
\placeinitial\input ward
\stop

\start
\setupinitial[font=Roman at 32 pt,n=2,m=1]
\placeinitial\input ward
\stop

\start
\setupinitial[style=\it,n=2,m=1]
\placeinitial\input ward
\stop

\start
\setupinitial[font=Italic at 32 pt,n=2,m=1]
\placeinitial\input ward
\stop

\start
\setupinitial[style=\it,font=Italic at 32 pt,n=2,m=1]
\placeinitial\input ward
\stop

\stoptext

Are my expectations wrong?

[NTG-context] Testing for LMTX: \ifmode

[Axel Kielhorn]

Hi,

I have a document that doesn’t work with LMTX right now.

While testing LMTX I would like to exclude certain passages and work on them 
later.

When I run the following:

\doifmode{*mkiv}{mkiv}
\doifmode{*contextlmtxmode}{contextlmtx}
\doifmode{*lmtx}{lmtx}

I always get „mkiv“.
I’ve tried

- pre LMTX context
- LMTX --luatex 
- LMTX (2021.07.23)

What is the recommended way to detect LMTX?

Greetings
Axel

[NTG-context] Making text disappear depending on mode

[Axel Kielhorn]

Hello,

I’m currently writing an article for „Die TeXnische Komödie“ and discovers that 
my code is not working.

When the mode „change“ is set, the text should appear with a red line on the 
side,
that part is working.
When the mode is not set, it should disappear,
that’s the part that is not working.

My idea was to put the text into a buffer and ignore it, that didn’t work.


% !TEX TS-program = ConTeXt (LuaTeX 1.0.9)
% !TEX encoding = UTF-8 Unicode

%\enablemode[change]

% Paragraph removed
\definestartstop[ChangePR][
  before={\doifmodeelse{change}
  {\startsidebar[rulecolor=red]}
  {}},
  after={\doifmodeelse{change}
  {\stopsidebar}
  {}},

%{\startsidebar[rulecolor=red]}
%{\startbuffer[ignore]}},

Some programs have dependencies on texlive.
These are usually programs that create pdf via TeX.

Glad I could help you.

This looks like a Macports installation.

When I call the Macports version of context I get:

context --help

mtxrun  | unknown script 'context.lua' or 'mtx-context.lua'

If you want to use the Macports version of ConTeXt please install

port install textlive-context

after installing that I get:

Should the comment in the engine file change?

Context is called with:

mtxrun --script context --autogenerate --synctex=1 "$1“

Well, one more suggestion:
Use TeX Live Manager to update TeX-Live.
I didn’t see any comments about context not working, but maybe the update fixes 
something.
(You can filter for context related packages.)

There has been one update to „context“ in June 2020.

Well, it works here on a (relatively) clean install of 10.13.

It should work.

One more thing:
Please look at environment variables starting with TEX and comment them, they 
will cause problems.

And another one:
Please look into the home directory for a local .texlive2020 folder.
There shouldn’t be any and it shouldn’t contain anything context related.

The TeXshop engine file says:

# Before using this engine, you must run the following command once in 
Terminal: luatools --generate

I probably did this when I installed TeXLive.

But I’m a little irritated by /sw/bin/.
Is this a real MacTeX installation and not something like homebrew?

Let’s start with the simple things:

What is the result of:
which context

it should be:
/Library/TeX/texbin/context

If that doesn’t work try:

which pdflatex

The result is probably not

/Library/TeX/texbin/pdflatex

but should give some indication where to look.

There may be an old installation of MacTeX without Context somewhere in the 
path.

If this is an old TeXShop installation, the Context engine may need an update 
because it points to the old PATH.
Simply copy the engine from ~/Library/TeXShop/Engines/inactive/ConTeXt to 
~/Library/TeXShop/Engines

Hope this helps
Axel

I updated LMTX on MacOSX 10.13 today.

The luatex binary in not executable, thus when I run

axel$ context --luatex --version
mtx-context | redirect luametatex -> luatex: luatex --luaonly 
"/usr/local/texlive/LMTX/tex/texmf-osx-64/bin/mtxrun.lua" --script mtx-context

mtx-context | current version: 2019.03.21 21:39

it picks up the TeX-Live version.

after I 

axel$ chmod 744 luatex 

I get the correct version:

axel$ context --luatex --version
mtx-context | redirect luametatex -> luatex: luatex --luaonly 
"/usr/local/texlive/LMTX/tex/texmf-osx-64/bin/mtxrun.lua" --script mtx-context

Re: [NTG-context] XML to ConTeXt: converting date attribute from ISO date

[Axel Kielhorn]

Hello Hans and mailing list!

Thank you so much.

With this example and the help I received earlier from Massi, 
I’ve been able to write my first finalizer today.

It is amazing how powerful luatex is.

My project needs some cleanup and documentation but I hope to put it on GitHub 
soon.
After that I will try to put a minimal version into the wiki.

This is strange.
Now it works.

Earlier I had context.date complaining that it got a table and not a string.
That’s why I took the t = assignment apart into pieces.

Now I copied the code from the original reply and it works.

Sorry for the noise.

I couldn’t get this to work.
Had to change it to:

\startluacode
   function xml.finalizers.tex.MyDate(e,what,how)
   local ee = e[1].at[what]
   local t = (string.split(ee,"-"))
   context.date(
   { y = t[1], m = t[2], d = t[3] },
   { how }
   ) 
   end
\stopluacode

[NTG-context] Need help processing XML in luacode

[Axel Kielhorn]

Hi,

after one year I’m back at a project processing XML with ConTeXt.

Here is what I want to do:
I have an XML file that I want to format with ConTeXt.
I got this working last year.

Now I want to take some information from a second file.

My idea is to read the second file, store the data into a table and 
write auxiliary functions to access the data and insert them into the TeX 
output.

When I process the included files with

context --environment=prozess-style-ecm.tex prozess.xml

I get

[ctxlua]:19: table index is nil

12 
13 doc = xml.load(doclistfile, settings)
14 
15 for v in xml.collected(doc,"/doclist/psdoc/") do
16  -- print ((xml.filter(v,"//docnr/stripped()")))
17  docnr = (cropstring(xml.filter(v,"/docnr/text()")))
18  docname = (cropstring(xml.filter(v,"/docname/text()")))
19  -- es kann mehrere DOCAN geben!
20  docan = (cropstring(xml.filter(v,"/docan/text()")))
21  docverantwortlich = 
(cropstring(xml.filter(v,"/docverantwortlich/text()")))
22 >>   docstruktur[docnr]={}

The xml.collected works, but the xml.filter returns nil.

What did I miss?

mtx-context | ConTeXt Process Management 1.03

mtx-context | main context file: /Volumes/Macintosh

mtx-context | current version: 2020.01.30 14:13

The same code works when I use it in a Lua file that I call with

mtxrun --script panalyse.lua

I had the same problem with an „ä“ in one of my elements.

Took some time to discover that.

[NTG-context] Reading XML with lua

[Axel Kielhorn]

Hi,

I’ m finally at a point where I can read an XML file look at it and write it 
back.

Right now I have two problems:

1. There are many empty entries in the table.
This makes processing the file a little tedious since I have to filter the real 
entries.

2. Some entries contain leading and trailing whitespace and linkebreaks.
These are the result of formatting the XML file.
Shouldn't
strip_cm_and_dt
take care of them?
Or do I use that incorrectly?

I have included my lua file and an example xml.
You can run it with
mtxrun —script p.lua

A leftover from merging two documents.
Once should be sufficient.
I’m not sure if it was a good idea to use german names for the elements.
Using english names and making the language configurable may be the next step.

Right, I startet out \xmlflush{}ing everything and turned it into \xmltext 
later.
I missed this one.

Great, it works now.

I want to add
\xmltext{#1}{../../pverantwortlich}
to psindoc

And
\xmltext{#1}{../../pverantwortlich}
to psoutdoc

before writing the ps[in|out]doc to an extra file.

But thinking about it, it may be easier to load a  tree from 
a separate file
and add / edit the doc entries based on the .
(s are unique.)

This part isn’t even in my head now.

> Just in case it helps,

It did, thanks!
Right now the document does what I wanted to do in ConTeXt.
I’m tempted to write the remaining functions in lua instead of python.

Still a lot to learn ahead.

[NTG-context] Processing XML: Header and footer, data manipulation

[Axel Kielhorn]

Hello,

Pablo Rodríguez wrote in „From pandoc to ConTeXt“:

„So, if I was able to do this, probably anybody can do it.“

Well, I tried and indeed it isn’t as difficult as i thought.
(Once I learned that an entity must not contain non-ASCII characters.)

Some questions remain:

I want to set page headers based on information I get from the XML:

\startxmlsetups xml:prozess
  \mainlanguage[de]
  \setupheadertexts[\bf\xmltext{#1}{/pnr} \xmltext{#1}{/pname}][\date]
  {\bTABLE
\setupTABLE[frame=off]
\setupTABLE[offset=1mm]
\setupTABLE[c][1][align=right, width=14cm]
\setupTABLE[c][2][align=left,  width=6cm]
\setupTABLE[c][3][align=right, width=4cm]
\bTR \bTD \bfb\xmltext{#1}{/pnr}   \eTD \bTD Version:\eTD \bTD 
\bf\xmltext{#1}{/pversion}\eTD \eTR
\bTR \bTD \bfb\xmltext{#1}{/pname} \eTD \bTD Verantwortlich: \eTD \bTD 
\bf\xmltext{#1}{/pverantwortlich}\eTD\eTR
  \eTABLE}
  \blank
  \xmlflush{#1}
\stopxmlsetups

This works on the first page (when the document has more than one page) but 
headers and footers are empty on subsequent pages.

Something (xmlflush?) overwrites my setup.
Any idea how I can fix that?

I want to use xmlconcat here, since there may be more than one docan, but I 
only get the „, “

\startxmlsetups xml:psoutdoc 
%\inmargin{\xmltext{#1}{/docan} $\Leftarrow$}  {\bf 
\xmltext{#1}{/docnr}}\xmlflush{#1}
\inmargin{\xmlconcat{#1}{/docan}{, } $\Leftarrow$}  {\bf 
\xmltext{#1}{/docnr}}\xmlflush{#1}
\xmlsave{#1}{outfile.xml}
\blank
\stopxmlsetups

I want to write the nodes psindoc and psoutdoc to a separate file.
\xmlsave overwrites the file, is there a way to append to the file? (or append 
to a buffer and write the buffer?)

\startxmlsetups xml:psindoc
\inmargin{\xmltext{#1}{/docverantwortlich} $\Rightarrow$} {\bf 
\xmltext{#1}{/docnr}}\xmlflush{#1}
\xmlsave{#1}{outfile.xml}
\blank
\stopxmlsetups

Can I add child notes to #1?

The last two questions probably require LUA, what is a good way to start 
learning LuaTeX?

I enclosed a small test file.

Shouldn’t \spaceddigits use the separator as defined by \setdigitmode and

[NTG-context] Documentation of change / Evolving documents

[Axel Kielhorn]

Hi,

I often have documents that are not finished but need to change over time.
A client changes their mind, laws are changed, …

While working with the document, I want to see the changes.
When the document is finally finished, I only want to see the change history.

I came up with the following.
When the mode is „change“  the date (or version) is shown in the margin and the 
change is printed in red.
Without mode „change“ only the change history is printed.

What I want now is to change the layout of the register.
Adding some vspace around the date and printing the date in bold.
Is there a way to achieve this or am I on the wrong way?
(Should the date be the indicator, thus giving me the layout I want?)

\enablemode[change]

\setuppapersize [A4][A4]
\setuplayout[width=middle,  backspace=1.5in, cutspace=1.5in,
 height=middle, topspace=0.75in, bottomspace=0.75in]

\setupbodyfont[11pt]

\defineregister [change]
\setupregister  [change] [
  indicator=no  %% no letter
  style=sansbold,   %% headings
  textstyle=slanted,%% entries

%% Tagged PDF

\setupbackend[export=yes]
\setupstructure[state=start,method=auto]

\starttext

\chapter[chap:testing]{Testing}

Das kann man auch als Textformel darstellen: \chemical{2 H_2,PLUS,O_2,GIVES,2

\input tufte

\stoptext

If I include the \chemical command inside a

\startchemicalformula \stopchemicalformula

everything works.

What am I missing?

With this information I found:

https://wiki.contextgarden.net/Unexpected_behavior#Footnotes:_The_Difference_between_.5Csetupnotation_and_.5Csetupnote

The headcolor in \setupnotation is actually the color of the marker in the note
while the maker in the text is defined with \setupnote.

I guess I have to request edit rights for the garden.

The page mentioned above offers the following solution:

\definenote[commentnote][endnote]  
  \setupnotation[commentnote] [color=red,left={(},right={)}]
  \setupnote [commentnote] [textcommand=\mycommentcommand]
\define[1]\mycommentcommand{\high{\tfxx(#1)}}

Thanks for pointing me in the right direction.

Those by the original author and those by the translator.

I want to show the translator notes in a different way.
Right now I have the footnote in green, but the footnote marker in the text 
does change neither font nor color?
Shouldn’t the marker be green and bold?
Setting numberconversion works, but the other options seem to be without effect.

I want to include longer note as endnotes.
I can change the marker shown with the notes to (1) but he marker in the text 
does not change.
Thus you can’t distinguish between a footnote and an endnote.

I tried a footnote within a footnote, that didn’t work, should it?
(I don’t actually need this, I was just curious.)

When I define commentnote based on endnote I get the same numbering.
How can I either
- use different counters for both kind of notes or
- print both notes with the same placenotes command, in the right order?

Greetings
Axel

I’m trying to do that, but I’m a slow learner.

The version I write is in german, but once it is finished it should be easy to 
translate it into english.

Having a short introduction was a great help when I learned LaTeX, writing an 
introduction will probably be a great help to learn ConTeXt.

There is still a lot missing, but you can get a glimpse at:

I used MkIV syntax for \startsection \stopsection but gave up on 
\startparagraph \stoparagraph.

Is there a way to auto convert that or do I have to add these command once I

[NTG-context] German introduction to context

[Axel Kielhorn]

Hello,

I’m looking for an introduction in german.
What I need is:
- Structure chapter/section …
- Emphasis bold/italic
- lists itemize
- floats
- TABLE
- index
- references
- math (with units)
- chemistry (only basic stuff)

Several years ago I started to prepare a talk for a DANTE meeting, trying to 
show how to generate epub from context.
Since I got a new job in early 2015 I didn’t have time to finish the talk or go 
to the meeting.
I’ll use the enclosed text as a starting point, unless someone already has a 
usable manual.

Note: Dominik Wagenführ was an editor of the now defunct „Freies Magazin“ and 
he supplied a LaTeX document of examples that needed to be converted into ePub. 
Thus the enclosed document is mainly concerned about epub.

Greetings Axel

[NTG-context] Formulas in TABLE with character alignment

[Axel Kielhorn]

Hello,

I decided to use TABLE because I may need some more complex layouts later and 
want to use just one way to define a table.

One of the great things about TABLE is the possibility to align columns.
The table below works fine when I comment the first \bTR line.
With the first line the result is strange.
I need some way to protect the words in the header, putting them in an \mbox 
didn’t help.

\starttext
{
\setupTABLE[row][each][frame=off]
\setupTABLE[c][1][width=0.1\textwidth]
\setupTABLE[c][2][width=0.1\textwidth,alignmentcharacter={,},aligncharacter=yes,align=middle]
\setupTABLE[c][3][width=0.1\textwidth,alignmentcharacter={,},aligncharacter=yes,align=middle]
\setupTABLE[c][4][width=0.1\textwidth,alignmentcharacter={,},aligncharacter=yes,align=middle]

\bTABLE
\bTABLEbody
\bTR \bTD\eTD \bTD \chemical{NH_3} \eTD \bTD R407C  
   \eTD \bTD R134a  \eTD \eTR
\bTR \bTD \math{t_s} \eTD \bTD \math{p_s}  \eTD \bTD \math{p_s} 
   \eTD \bTD \math{p_s} \eTD \eTR

I appreciate that.

How about offering a skeleton project for download?

Here is my corrected ECM with the following README:

This is a skeleton project.
You can copy it and change the files to contain your content.

The top level project collects metatdata to make all products have the same
layout. It is not meant to be processed by context.

The products are used to generate the whole book, but you can process each
component seperately to reduce the processing time.

I see.
I’ll probably keep it as three books.
It’s easy to change later as long as the components have different names.
Right now that’s just a limitation of the word processor.

Works here as well, thank you.
What about the project?
Right now it is outside the \start{product|component} and it works.

Now it is inside the \start{product|component} and it works as well.

Next question:
Should the environment be inside \startproject \stopproject?

It seems to make no difference.

Thus having the whole file inside \start{project|product|component} \stop… 
would be a good idea and consistent.

Thanks for the quick response, now I can tell pandoc to convert the book to 
context:-)

[NTG-context] Need help with project: TeX capacity exceeded

[Axel Kielhorn]

Hello,

this is my second try to start with context and I can’t even do the first step.

I’m planing to convert a large but simple document to context.
The document consists of 3 Parts.
Each part has several chapters.

Thus I started to build a project with three products, see enclosed archive.

According to my understanding I should be able to
context c_01 to get one chapter
context prd_A to get one product
context project_ecm to get the whole book.

The first two steps lead to circular inclusion and the TeX capacity error.
The last step doesn’t load the products and creates no files.

I got my information from

https://wiki.contextgarden.net/Project_structure

and think I adapted them correctly, but obviously I didn’t.

I included the log files in case there is something broken with my setup.

Greetings
Axel

You probably had to include 
/Applications/LilyPond.app/Contents/Resources/bin
into $PATH.

This PATH is only known in the Terminal.
When you call ConTeXt from the GUI (via TeXShop) you only have the default PATH.

Since TeXShop calls context via an engine file, you can add the PATH in the 
engine:

Change this line (actual path to context may differ):

set path= (/usr/local/texlive/context/tex/texmf-osx-64/bin /usr/local/bin $path 
)

to

set path= (/usr/local/texlive/context/tex/texmf-osx-64/bin /usr/local/bin 
/Applications/LilyPond.app/Contents/Resources/bin $path )

You will find the engines in:
~/Library/TeXShop/Engines

 To the list members: could you test the sample above and tell em- and

 may help.

I’m using 
current version: 2015.07.12 00:00
on MacOSX 10.10

I get ligatures in both cases and neither em nor en dash.

Now I have
current version: 2015.07.12 15:40
still on MacOSX 10.10

No ligatures in the second case and both en and em dash.

[NTG-context] Context to epub: itemize

[Axel Kielhorn]

Hi,

I'm trying to generate epub from ConTeXt and I couldn't get the itemize 
environment to work.

I follow http://wiki.contextgarden.net/ePub and get the structure described but 
when I look into the xhtml, there is no itemize environment. (At least no with 
Safari, Firefox or Calibre.) When use vi I see something that looks like my 
items in a very complex form.

I was expecting something like

ul
  li   /li
  li   /li
/ul

but i see

div class=itemgroup itemize level-1 symbol-1
  div class=item
div class=itemtagm:math display=inline 
xmlns:m=http://www.w3.org/1998/Math/MathML;m:mo•/m:mo/m:math/div
div class=itemcontentListenpunkt 1/div
  /div
  div class=item
div class=itemtagm:math display=inline 
xmlns:m=http://www.w3.org/1998/Math/MathML;m:mo•/m:mo/m:math/div
div class=itemcontentListenpunkt 2 
  div class=itemgroup itemize level-2 symbol-2
  div class=item
  div class=itemtagm:math display=inline 
xmlns:m=http://www.w3.org/1998/Math/MathML;m:mo−/m:mo/m:math/div
div class=itemcontentListenpunkt 2.1/div/div 
div class=item
div class=itemtagm:math display=inline 
xmlns:m=http://www.w3.org/1998/Math/MathML;m:mo−/m:mo/m:math/div
div class=itemcontentListenpunkt 2.2/div/div/div/div
/div

Shouldn't the itemtag definition come from the default.css instead of using 
MathML?

itemgroup[symbol=1], div.itemgroup.symbol-1 { list-style-type : disc ; }

I’m using: mtx-context | current version: 2015.02.03 23:55

and

context --script epub --make epub_mwe

to create the epub.

 Hi,
 
 I'm trying to generate epub from ConTeXt and I couldn't get the itemize 
 environment to work.
 
 I follow http://wiki.contextgarden.net/ePub and get the structure described 
 but when I look into the xhtml, there is no itemize environment. (At least 
 no with Safari, Firefox or Calibre.) When use vi I see something that looks 
 like my items in a very complex form.
 
 I was expecting something like
 
 ul
   li   /li
   li   /li
 /ul
 
 but i see
 
 div class=itemgroup itemize level-1 symbol-1

 div class=itemcontentListenpunkt 2.2/div/div/div/div
 /div
 
 Shouldn't the itemtag definition come from the default.css instead of using 
 MathML?
 
 itemgroup[symbol=1], div.itemgroup.symbol-1 { list-style-type : disc ; }
 
 I’m using: mtx-context | current version: 2015.02.03 23:55
 
 and
 
 context --script epub --make epub_mwe
 
 to create the epub.
 
 the bullets come from math fonts (currently, awaiting additional symbols in 
 the text fonts)


Yes I know.
Let me rephrase the question:

Should the symbols used in epub be identical to those used in the pdf or should 
the css determine the look of the symbols?
Especially when one considers that most current ebook readers can't display 
MathML.

Even if I substitute the Symbols:

\definesymbol[uni1][•]
\definesymbol[uni2][–]
\definesymbol[uni3][*]
\definesymbol[uni4][·]

\setupitemgroup [itemize] [1] [symbol=uni1]
\setupitemgroup [itemize] [2] [symbol=uni2]
\setupitemgroup [itemize] [3] [symbol=uni3]
\setupitemgroup [itemize] [4] [symbol=uni4]

I get a result that neither ADE nor Calibre interprets as a list.
(Wrapping it in ul /ul doesn't help.)

[NTG-context] \setupbackend and manual hyphenation

[Axel Kielhorn]

Hi!

I'm trying to use Context to export a document to epub.
Following the instructions on Contextgarden everything works up to a point:

When I add manual hyphenation for the word Trennalgorithmus and
\setupbackend[export=yes,xhtml=yes]
I get:

See attached log file.

If I remove the hyphenation, everything works, but the hyphenation is wrong.

I'm using:
current version: 2015.02.03 23:55

 for the moment use
 
 \setuphyphenation[method=expanded]

This works in the current beta, but not with the stable version in TeXLive 2014.

It doesn't matter since I need the beta to create epub, just wanted to mention 
it.

Thanks for the quick reply.

Re: [NTG-context] Context modules not on CATN and not in TeX Live (slightly OT)

 Hi Alex,
 
 The simple answer to your question would be to use this page:
 
 http://www.ctan.org/upload/
 
 No, in case of ConTeXt that's not correct. The idea would be to handle
 everything automatically once the modules are uploaded to
 modules.contextgarden.net. Some discrepancies are intentional, some
 are bugs (read as: nobody noticed that a module was missing and/or
 bothered requesting it).

That's what I was hoping.

 I would suggest that you point them to the Standalone stable release,
 if you actually need the missing third party modules.
 
 No, wait, let's try to clear things up first.
 
 If modules should be on CTAN and aren't, I'll add them to CTAN. If
 modules are on CTAN, but not in TeX Live, we should figure out why
 they are excluded from TeX Live and either make sure that they are
 either added to TeX Live (if there are no problems with licencing,
 packaging etc.) or removed from CTAN (in case they are not really
 useful). We could keep some modules on CTAN if they are useful, but
 don't qualify for TL inclusion for some obscure reason.

Two modules that are on CTAN but not on TeX Live are the URW font support files.
The fonts are non-commercial thus the support files are not included.
The fonts are on CTAN and there is a utility to install them to texmf-local.

(Probably not needed for MkIV.)

 Don't use TeX Live could be the proper advice for someone who wants
 to use the latest version of ConTeXt, but one shouldn't confuse the
 user just because a module is missing in TL by accident.

I prefer the Everything is already on your computer, let's try it!
approach. Having to install (and maintain) a second system makes it difficult 
to convince someone to try ConTeXt.

Maybe the install instructions on the wiki should be amended for TL 2014.
I look into that once the visualcounter is in TeX Live:-)

[NTG-context] Context modules not on CATN and not in TeX Live

[Axel Kielhorn]

Hi!

I'm trying to learn ConTeXt working through some examples I found on Context 
Garden and the internet.

Since I already have TeX Live 2014 installed I could run most of the examples.
When I ran into a problem, I installed the standalone version and compared the 
supplied modules.

The following modules are not part of Context in TeX Live 2014.

 animation/ GPL 3
 annotation/GPL 3
 cmscbf/GPL 2  on CTAN
 cmttbf/GPL 2  on CTAN
 fancybreak/GPL 3
 layout/GPL
 title/ GPL 3
 urwgaramond/   GPL 2  on CTAN
 urwgothic/ Public Domain  on CTAN
 visualcounter/ Simplified BSD License

Some are on CTAN, some are missing there.
Since TeX Live takes the files from CTAN, it would be nice to put the missing 
modules there. 
What is the correct way to do that?

I ask because I want to give a tutorial about ConTeXt at the Dante meeting in 
april and it would be nice to tell the audience that everything they need is 
already part of TeX Live and no extra installation is required.

Axel
