btex ... etex is parsed as-is and therefore cannot be uses

this is what the macro textext(...) is for, it writes the (expanded)

Dear ConTeXters,

At the moment I am bit at a loss.
I should prepare a document, wherein there will be a difference 
between one chapter title and the respective row in the table of

\chapter{This is the title of the chapter}

In the table of contents it should show up as:

Epilog: This is the title of the chapter

So the question is, how to get the word Epilog into the table of 
contents in front of the chapter title, neatly aligned with the rest 
of the table of contents.


each time ... then hook it into the list command

once: then do something like:

 thank you



Better in matters of logical markup would be a definition like  
\quotation, say \exclamation or \question,
but I don't know if there are languages other than Spanish that need  
additional signs/formatting for those...


interesting suggestion, we can use the delimited text mechanism for it 
(core-mis);  what do the spanish users think of if?

Hi Fabio,

sorry, my first advice was bad. In the meantime I have played around
with columns and everything is working as expected. There are several
problems in your source. The first is, that you have to use

\setuplayout[grid=yes]

Read about grid snapping of headers in the details.pdf manual and look
into the columns environment (defined at the beginning of the columns
manual).

You can then adjust the headers (2 lines high) vertically by using the
'grid' parameter.

The problem with the graphic placing results from using \startcolumns
instead of \startcolumnset (see example in columns.pdf).

I attach my working example.

Greetings, Peter

Hi David,

Put the x into a variable:

\setMPtext{1}{x}

you can define the \stetMPtext within the \starttext \stoptext or outside

Call
create_axes(xmin,xmax,ymin,ymax,ux,uy)(\MPbetex{1});

[NTG-context] \startMPpage ... \stopMPpage

2005-12-26 Thread David Arnold 

Hans, Taco, et al,

There's a quote in metafun-s.pdf (page 539) that says You can embed  
the graphic in a \startMPpage construct and process it with TEXEXEC.  
In that case you have the full MetaFun functionality available.  
Before processing the file, TEXEXEC will do a couple of checks on the  
file. It will also make sure that the auxiliary files (mpt for  
textext’s and mpo for outline fonts) are taken care of too.


I am really unsure of what this means as the code below will attest.  
Simply uncomment


% \startMPpage
%   \includeMPgraphic{EnglishRule}
% \stopMPpage

at the end and the file will not compile.

Just what can and cannot be used between a \startMPpage ...  
\stopMPpage pair? This is first introduced in metafun-s.pdf on page  
214 and wish there were more said there.

All,

In mp-grid.mp, I find this definition:

def hlingrid (expr Min, Max, Step, Length, Width) text t =
image ( for i=Min step Step until Max+grid_eps :
  draw (origin--(Width,0)) shifted (0,i*(Length/Max)) t ;
endfor ; ) ;
enddef ;

See the text t at the end of the first line? Can someone tell me what 
that does and can I have a small example of its use?


I think, (I can not test it right now), that this should allow you to 
do things like


hlingrid(0,10,0.1,5cm,3cm) withcolor 0.5white ;

which will draw the line with 50% gray, and

hlingrid(0,10,0.1,5cm,3cm) dashed evenly ;

which will draw a dashed grid and so on.
