Re: [NTG-context] Opentype features and space after comma in math mode

2017-06-01 Thread Jose Luis Arellano 
Dear Wolfgang.

In recents versions of Context, what is the correct way to use lnum feature
in maths?

This doesn't works anymore:

\definefontfeature[mathdigits][default][mode=base,tnum=yes,lnum=yes]
\definefallbackfamily[mainface][math][...][preset=math:digitsnormal,features
=mathdigits]

Thanks in advance.

José Luis,

I think that line should read:

\definefontfeature[mathdigits][mode=base,tnum=yes,lnum=yes]

But without a sample, I’m afraid I cannot test it.

Just in case it might help,

Pablo

Many thanks for your reply, Akira.

I didn’t check my code on Windows (all my computers at home run Linux).
I’m suprised that it worked.

And thanks for warning about the path and %USERPROFILE%. Of course,
ConTeXt and LuaTeX do magic, but organizing files is a task that belongs
to the user ;-).

Many thanks for your help,

[NTG-context] a special kind of notes in each page

2017-06-01 Thread Pablo Rodriguez 
Hans,

I have a document http://tex.ousia.tk/hippocratic-oath.pdf (source as
attachment to the PDF document itself).

The special kind of notes are the first group in two columns. I need
that their space and location in page are calculated by the notes
mechanism. And also that the notes mechanism selects the range of notes
that belong to the page.

I don’t need any reference, not to note number or to line number. Since
it is a vocabulary list, what I need is a minimal register with
"indicator=no, before=, after=".

So it would be possible to have well-balanced columns and words
alphabetically sorted, which is essential in a vocabulary.

I guess that \definenote[NAME][alternative=register] and
\setupregister[NAME][indicator=no, before=, after=] could be a good way
to invoke these page-related vocabularies.

Would it be possible to have such a feature? This would the way to have
page vocabularies.

Many thanks for your help,

Pablo

[NTG-context] ConTeXt Meeting 2017

2017-06-01 Thread Taco Hoekwater 
Hello everybody!

== Announcement ==

The ConTeXt Group and Pragma ADE are looking forward to welcoming you at the 

 11th International ConTeXt Meeting

that will take place on September 11–17, 2017 in Maibach, Germany. 


The meeting will host ConTeXt and LuaTeX developers and users and gives 
you the opportunity to present your results, experiences and ideas on future
development. The presentations will be accompanied by tutorials on different 
ConTeXt and LuaTeX techniques.

Registration is now open.  Direct link to the registration form:

  http://meeting.contextgarden.net/2017/register.shtml

This year’s meeting is sponsored by DANTE e.V., the German TeX User Group. 
Besides the general sponsorship, they also offer an extra discount for any 
Dante members that will attend our meeting. And that is on top of the discount
we offer to our ConTeXt Group members, so we managed to keep the conference
fees quite low.

== Call for submissions ==

We always set a theme for the meeting, and the theme for this meeting is:

 ConTeXt Gardening

If you want to do an on-topic talk submission, there are plenty angles
to take at the theme: Seeding, weeding, fertilising, growing, harvesting,
just to name a few.

But anything at all related to ConTeXt that you would like to share is an 
acceptable subject for a presentation, tutorial, discussion, Q session, 
demonstration, workshop, recital, sketch, or sermon.

The programme committee is Hans Hagen and Taco Hoekwater, feel free to email 
them 
with hints and ideas.
