Re: [NTG-context] Asymptote or Metapost and ConTeXt parameters.

The ability to pass parameters to metapost has been around since the 
beginning. See the metafun manual for details (search for MPvar). For 
simple images, you can also do:


\define[1]\Circle{\startMPcode draw fullcircle scaled #1*cm; \stopMPcode}

\Circle{1} \Circle{2} \Circle{3}

Is there a way to pass the ConTeXt parameter which influenced the 
creation of the Asymptote image? My point eg. the ability to define 
macros, which gave its parameters to Asymptote procedure or function and 
depending on these parameters, the image created by Asymptote looked 
differently.


In principle, something similar to \MPvar can work for asymptote as well 
(or one could do parse the content in Lua rather than expand variables in 
TeX).


Before starting work on an illustrative example I am asking, whether it 
makes sense to deal with such a thing ... I suppose the impossibility of 
combining asymptote code and such Lua code (or not?).


ConTeXt and Metapost are very well integrated, even in MkII. The same 
ideas could work with other graphic backends as well (Asymptote, tikz, and 
others). But it does require a good knowledge of the graphics package.


I am willing to write the code at the context end, if someone who knows 
asymptote can tell me what needs to be done at the asymptote end.

[NTG-context] \setupfooter[color=red]: red color spills with float over next page

2016-12-19 Thread Benjamin Buchmuller 
Hi Hans,

the patch solves the issue. Thank you for the fast reply.

With regard to Pablo’s question: When I would not use crop in the MWE, 
apparently I would get the desired output indeed. However, in the situation I 
was using the command to produce a document, I would need to crop some parts of 
a figure. I should have been a little bit more clear on this, I guess.

Thanks again,


Benjamin

Dear list,

(I got some information offlist from Hans regarding NAW, it seems they
used an old pdftex-based hacked version)

I gave no example. I decided now that I would like to try the new
pagegrid out (loaded via newcolumnsets module now). But I somehow fail
even with a simple(?) example: Could someone point out what I do
wrong? If you have a small snippet of working code (even with
columnsetspans, I left them out since I think this simpler document
must work first) I'm very happy to look at it.

Also, the placement options for \placefigure seem to be ignored (try
for example bottom). Are they not implemented yet?

Best regards, Mikael

% start of example
\usemodule[newcolumnsets]

\setupbodyfont[9pt]

\definecolumnset[example][n=2]

Imho while you can use packed locally unpacked is only for global
settings. At least it isn't mentioned as argument here
http://wiki.contextgarden.net/Enumerations

It works if you use unpacked in another \setupitemize:

\setupitemize[each][unpacked]

Then the cleanest (and most ConTeXt-like) solution would be to define 
several instances of itemize in the preamble and use those instead of 
applying the settings on the fly. 
(http://wiki.contextgarden.net/Command/defineitemgroup , but I guess you

Hello,

yes, that's right; but I thought there is an option to "override" the 
default/set-up setting -

- what should "unpacked" do otherwise?

Also, in my case, there are more \itemize to be packed; and some of them (in the middle

comfortable here.
