the latest lmtx should be ok (predefines language zero)

but wolfgangs suggestions are the ones to follow ... language=0 is a 
hack, just as is setting left/right hyphenmin so we now have a proper 
disabler (in luametatex/lmtx that is; luatex/mkiv should not be affected)

This is a leftover from the old days. Thank for the suggestion on how to fix 
this. I'll play around a bit and perhaps add the  option `hyphens=yes|no`  
instead of the current `option=hyphenated`.

Thanks. I had:

   \doifnotinset{\v!hyphenated}{\externalfilterparameter\c!option}

Don't use the \language hack, the official and supported commands are 
\nohypens and \dohyphens or when you need a interface for it use


\usehyphensparameter\...parameter

which allows

\setup...[hyphens=yes|no]

Thanks. I had:

[NTG-context] update and meeting

2020-09-15 Thread Hans Hagen 

Hi,

I uploaded a new version. It is a follow up on the ctx meeting of last 
week (in a country side compound in czech with also some remote 
attendants, daily infrared health scans, an excursion, talks, breaks, 
food, and the usual have fun with context friends moments).


There are a few changes that can affect users numbered 1 and 2 below.

(1) During one of the coffebreak discussions we agreed to drop the two 
units that were never official and are kind of meaningless: 'nc' (new 
cicero) and 'nd' (new didot). Arthur made some stroing arguments and 
only Tomas remembered ever entering one of them so there was no resistance.


We also considered that in order to enforce the use of si units the 'in' 
should go away but that has been postponed (it is anyway last in the 
checked keywords so has no overhead).


At some point the "true" prefix might go too (never really used, but no 
overhead either).


(2) Another change is in the \startdocument mechanism. This (already old 
and rusted) wrapper runs on top of variables but we think no one knows 
(or uses) that. So, it now is a real wrapper with inheritance and such. 
It is dedicated to Tomas Hala who had to struggle with the old one but 
still gave a presentation using it. Here's an example:


\definedocument[thesis]

\setupdocument[a=b,e=f]
\setupdocument[thesis][a=x,c=d]

% \startsetups[thesis:start]
\startsetups[document:start]
START
\stopsetups

\startsetups[thesis:stop]
% \startsetups[document:stop]
STOP
\stopsetups

% \startdocument[thesis]
\startthesis

(\currentdocument/a): \documentvariable{a}\par
(\currentdocument/c): \documentvariable{c}\par
(\currentdocument/e): \documentvariable{e}\par

\stopthesis
% \stopdocument

There's also a user mode set with the document enviroments name.

(3) Some other additions are for Taco so will not be disclosed here (yet).

(4) There are some summaries of my presentations added to the 
distribution (the wiki will collect more at some point).


1 context-2020-mkii-mkiv-mkxl.pdf
2 context-2020-luametatex.pdf
3 context-2020-concepts.pdf
4 context-2020-tokens.pdf
5 context-2020-implementers.pdf
6 context-2020-datatypes.pdf
7 context-2020-ecmascript.pdf
8 context-2020-svg.pdf
9 context-2020-mp.pdf

They use the new 'boring' presentation style and most are probably 
useless without demos and discussion but anyway ...  The first one is an 
overview of the three successive context versions. The second one is 
about the state of luametatex and the third discusses a couple of things 
introduced last year (luametatex and lmtx). The tokens talk is for low 
level tex lovers (or those who need to impress other texies with token 
speak), and the talk about implementers was probably only useful for 
wolfgang and me, but who knows. The datatypes are an overview over what 
is standard in tex and in lua as well as what we have extra on top of 
that. The seventh talk fits in the 'we also need to have some fun 
talks', and the eigths one was for a large part a discussion and 
accompanied by a demo by Hraban. The last one is (of course) also a fun 
one and (of course) discusses Don Knuths latest font which (of course) 
is kind of special


Anyway, it's all part of the 'we keep going' story, which is why they 
are in the distribution.


(5) We had several talks / discussions about the greatly improved wiki 
and users are invited to participate in completing the pages that need 
to be filled in, but I leave that to Taco to summarize.

I compile with TeXLive 2020 and Windows 10. I have the two fonts (New 
Athena Unicode and Old Standard) installed on my system but with New 
Athena Unicode it does not compile; on the other hand, with Old Standard 
it does compile. I do not know what I can do.


1. Remove the spaces from the key-val entries

2. Don't mix key-val entries with arguments

3. Load hyphenation patterns for greek (you can add them to spain 
because there is no overlap).


The following example works on my system but I suggest to add a math 
font (itemize uses math symbols as fallback).


\definefallbackfamily
  [mainface] [rm] [New Athena Unicode]
  [preset=range:greek,force=yes]

\definefontfamily [mainface] [rm] [TeX Gyre Pagella]

\definefontfamily [mainface] [ss] [TeX Gyre Heros] [scale=0.75]

You have to add \resetbreakpoints to the vim/filter module.
