[NTG-context] [***SPAM***] trouble with kerncharacters

2013-08-16 Thread Dmitriy Tokarev
Hi,

I noticed that after the command \kerncharacters, I can not use the normal 
sequence --- for em-dash. Is there any work around of this effect? Thanks.

\starttext

One monolithic symbol: ---

\kerncharacters[.5]
Three separate symbol: ---

\stoptext

[NTG-context] How to prevent moving figure on the next page?

2013-08-07 Thread Dmitriy Tokarev
Hi list,

I need help to undestand this effect: If setuphead[chapter][page=no] and after 
figure start a new chapter, than figure is moved to the page 2, although on 
page 1 space is enough. Thanks.

\setuppapersize[A5][A5]
\setupbodyfont[10pt]
\setuphead[chapter][page=no]
\showframe

\starttext
\chapter {One}

\dorecurse{2}{\input{knuth}}

\placefigure[here][figure]{Description}
{\externalfigure[figure][width=5cm,height=2.0cm]}

% if setuphead[chapter][page=no] and this comment transform to text, than 
figure moves to page 1. What do I need to figure always placing on page 1?

\chapter {Two}

\stoptext

[NTG-context] Setup font size by dimension variable

2013-08-04 Thread Dmitriy Tokarev
Hi all,

I want to set the font size by using the dimension variable, but it doesn't 
work. What am I doing wrong?

\definemeasure[AAA][20pt]
\newdimen\BBB \BBB=20pt

\starttext
TEXT

% don't work
\switchtobodyfont[\measure{AAA}]
AAA

% don't work
\switchtobodyfont[\the\BBB]
BBB

% ok
\switchtobodyfont[20pt]
TEXT 20pt

\stoptext

[NTG-context] [***SPAM***] Re: Setup font size by dimension variable

2013-08-04 Thread Dmitriy Tokarev
04.08.2013, 16:49, Philipp Gesang philipp.ges...@alumni.uni-heidelberg.de:
  the size-related arguments to \switchtobodyfont and
  \setupbodyfont aren’t real TeX dimensions but identifiers for
  predefined bodyfont sets. Example:

    \def\mainfontsize{20pt}
    \definebodyfontenvironment [\mainfontsize]

    \starttext
  TEXT
  \switchtobodyfont [\mainfontsize]
  TEXT 20pt
    \stoptext

  See this thread for some background info:

    http://www.mail-archive.com/ntg-context@ntg.nl/msg63901.html

 Sorry for the self-reply, but I just remembered that I already
 wikified the topic:

   http://wiki.contextgarden.net/unexpected_behavior#Treacherous_Dimensions


Thanks, Philipp!
Now I realized that before the first use of switchtobodyfont I need to write 
definebodyfontenvironment. In this case, everything is fine.
I also found another way without definebodyfontenvironment:

\definemeasure[AAA][20.123pt]
\newdimen\BBB \BBB=25.127pt

\starttext
TEXT

% ok
\normalizebodyfontsize\normalizedAAA{\measure{AAA}}
\switchtobodyfont[\normalizedAAA]
AAA \normalizedAAA

% ok
\normalizebodyfontsize\normalizedBBB\BBB
\switchtobodyfont[\normalizedBBB]
BBB \normalizedBBB

\stoptext

Is this code correct? Or it's better for some reason using 
definebodyfontenvironment?

But this compiled with an error:

Log file:

Is this a bug or a feature?

[NTG-context] [***SPAM***] Shifting table header when using overlay

2013-07-14 Thread Dmitriy Tokarev
Hi All,

I'm trying to get a table header with such bottom border:
||

I plan to use an overlay to overlap the the internal borders of the cells. But 
in this case, the table header somehow slightly shifted to the left relative to 
the body (see attachment). Is it possible to remove this effect? Or maybe there 
is another way to achieve the desired border? Thanks.

\startuseMPgraphic{MP:thickBtm}
   draw (0,2pt)--(OverlayWidth,2pt) withpen pensquare scaled 1pt withcolor red;
   clip currentpicture to OverlayBox;
   setbounds currentpicture to OverlayBox;
\stopuseMPgraphic

\defineoverlay[OL:thickBtm][\useMPgraphic{MP:thickBtm}]

\starttext
 \bTABLE
   \setupTABLE[align=middle]
   \setupTABLE[header][background={foreground,OL:thickBtm}]
   %
   \bTABLEhead\bTR\dorecurse{3}{\bTH#1\eTH}\eTR\eTABLEhead
   \bTABLEbody\dorecurse{6}{\bTR\dorecurse{3}{\bTD#1-##1\eTD}\eTR}\eTABLEbody

Re: [NTG-context] Learning ConTeXt from the Ground Up

2013-06-16 Thread Dmitriy Tokarev
 To gather information about ConTeXt I have
 - read the ConTeXt Reference Manual (http://pmrb.free.fr/contextref.pdf)
 - bought a couple of the published books by Hans Hagen
 - started reading the TeX book by Donald Knuth

In addition to the TeX book you might be interested in TeX for the 
Impatient:
http://www.ctan.org/pkg/impatient

see top of p.8 for recommendations for reading.
