But nothing happens. How do I get the effect earlier obtained with 
startMPenvironment without having to rely an a deprecated macro?


the bodyfont environment was needed because we had to communicate to the 
external mp run what the intended settings were


in mkiv the run is internal so the mp text generator adapts to the 
current settings and there is no need to pass anything

[NTG-context] How to get the current section level?

2016-04-03 Thread Lukáš Procházka 

Hello,

is there a (Lua) way how to get the current section level?

Something like:


\def\GetCurrentSectionLevel{%
  % What to come here?
}

\starttext
  \chapter{Ch}
\GetCurrentSectionLevel % Should yield "chapter" or e.g. 1 (meaning 
"chapter")

\section{Sec}
  \GetCurrentSectionLevel % Should yield "section" or e.g. 2 (meaning 
"section")

\subsubsection{SSSec}
  \GetCurrentSectionLevel % Should yield "subsubsection" or e.g. 4 (meaning 
"subsubsection")
\stoptext


Best regards,

Lukas

[NTG-context] Server down

2016-04-03 Thread Mojca Miklavec 
Hi,

For reasons unknown to me the contextgarden.net server is currently
down. The wiki (and some other components hosted at Taco's server) are
still working.

I have to wait until the network admin looks into the problem.

I'm really sorry for the inconvenience,
Mojca

[NTG-context] Margin text running off bottom of page

2016-04-03 Thread Robert Krug 
Greetings,

Is there any way to prevent marginal text from running off the bottom
ot the page? I can adjust the margin widths to prevent them from
running off the edges, but I cannot figure out how to do the same for
the bottom of the page.

\starttext

text.

\vskip 7.5in

text
\margintext{The book I am working with has marginal annotations that
act as a précis of the argument in the main text. Some of them are
several sentances long.}
text.

\stoptext

Robert

I couldn't find any details for that \leftboundary


spac-ver.mkiv:

it will instruct the protrusion checker to skip the next or
previous node (e.g. a char or hbox or ...) when looking for
an edge


Thanks for details. So if that worked with plain \hbox should be taken rather 
as coincidence?


a hbox becomes one node so that one node is ignored


I prefer motto the fewer commands, the better :-)

Re: [NTG-context] Alignment for narrower text

2016-04-03 Thread Wolfgang Schuster 

Jan Tosovsky 
2. April 2016 um 23:42
I thought Hans could also mean something like example below, but while 
leftskip should 'indent' all lines inside paragraph, it works only for 
the first one. Moreover, protrusion is not applied as well. And \crlf 
doesn't seem to be soft linebreak as it behaves like normal \par 
command - which is most likely explanation for that indenting issue.


{\leftskip=2cm
“line1\crlf
line2\crlf
line3\crlf
line4.
}
Indenting the whole textblock with \leftskip (or better ConTeXt’s 
narrower environment)

doesn’t prevent protrusion as can be seen in the following example.

\definefontfeature[default][default][protrusion=quality]

\setupbodyfont[modern-designsize]

\starttext

“\vl Text\par
 \vl Text

\startnarrower
“\vl Text\par
 \vl Text
\stopnarrower

\blank[3*line]\setupalign[hanging]

“\vl Text\par
 \vl Text

\startnarrower
“\vl Text\par
 \vl Text
\stopnarrower

\stoptext
