[NTG-context] Conflict between MetaPost (LMTX) and cmarrows

2021-04-25 Thread Jairo A. del Rio
The following:

\starttext

\startMPinitializations

input cmarrows;

setup_cmarrows(arrow_name = "texarrow"; parameter_file = "cmr6.mf";
macro_name = "nicearrow");

\stopMPinitializations

\startMPpage


nicearrow (origin -- (1cm*left));

\stopMPpage

\stoptext

compiles perfectly with ConTeXt MkIV. With LMTX, however, the following
happens:

metapost > initializing instance 'metafun:1' using format 'metafun' and
method 'default'

metapost > loading 'metafun' as 'metafun.mpxl' using method 'default'

metapost > initializing number mode 'scaled'

metapost > message : Loading cmarrows 2006/12/18, v0.9

metafun > log > overloading immutable 'eps'

(See the two

metapost > log >

What's happening? Is that intended or a bug?

[NTG-context] clubs and widows in columns

2021-04-25 Thread Jano Kula
Dear list,

is there a way to avoid clubs and widows in columns? I don't know, how it
would be implemented, if the task is splitting typeset vertical list.

\setuppapersize[A7]
\starttext
\startcolumns[separator=rule,
  align={right,nothyphenated}]
\dorecurse{12}{→ one two three four five\par}
\stopcolumns
\stoptext

For a different task: are there some higher level commands in ctx than
\vsplit primitive to play with vbox splitting?

Thank you,
Jano

Dear Keith and Mojca,

I followed the information provided buy Keith below and everything is working 
just fine. Mojca I directed my request to Keith in the first instance since I 
felt it was most likely my lack of knowledge of how to get things going that 
was the problem (as usual). So thank you for your quick response and offer to 
test. And thank you Keith for your example below it did the trick.

Very best wishes,
Charlie

Re: [NTG-context] How to write readable source files?

All is in xml files (i-*.xml) in the distribution maintained by

>dir t:\texmf\context\data

04/21/2021  11:40 AM  scite
04/21/2021  11:40 AM  textadept
04/21/2021  11:40 AM  texworks
04/21/2021  11:40 AM  vscode

these lists are generated by mtx-interface so we can add more if needed

I am married to Emacs but have an affair with Vim. ;-)

I use it from time to time including your plugin.

I don't have a strong opinion about indentation. So I won't mind if a
tool would just do it for me. But I understand your point. And I tend to
say that not indenting text between start-stop-commands is the way I
want my text.

I don't like to reflow paragraphs as I want to have one line for
each sentence. This is my only opinion about formatting text. Not
indenting is a good idea because sometimes I have really long lines and
identation would make them even longer.

I real IDE-like support for ConTeXt would be nice: setup-en.pdf is
always open when I write environments as I cannot remember all commands
and options. If my editor would give me a list of possible commands when
I just type some letters and then give possible options when I edit
inside a command – that would be great. 

Thanks a lot for your help
