Re: Asymptote or Metapost and ConTeXt parameters.

[Jaroslav Hajtmar <hajtmar@gyza.cz>]

Hello Adytia.
Thanks for sending Your code. It seems that it works with Asymptote. Unfortunately, when I am trying to multiple call a macro then I get fatal error, and then compile collapse. I do not know what it could be. Is it possible that my code is wrong. But it is possible that there is a stack overflow etc. It would be a need to look at why the fatal error occurs - It probably can evaluate Hans. Thanks again for your support. Below is my code. If removed commentary characters occurs advised error.

    It is already feasible to define something this simple using the filter 
    module. I don't have asymptote installed on the machine that I am 
    currently working on, but here is an example that uses pandoc.
    
    \usemodule[filter]
    
    \defineexternalfilter
         [MARKDOWN]
         [
           filtercommand={pandoc -f markdown -t context \externalfilterinputfile\space -o \externalfilteroutputfile},
           cache=yes,
           purge=no, % Just for testing. May be removed.
         ]
    
    \define[1]\TEST
         {\setbuffer[MARKDOWN]This is #1\endbuffer
          \processMARKDOWNbuffer[MARKDOWN]}
    
    \starttext
    \startMARKDOWN
       This is **one**
    \stopMARKDOWN
    
    \TEST{**ONE**}
    
    \TEST{_TWO_}
    \stoptext
    
    With this method, the results are not cached. Let me know if this works 
    for your needs.
