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.
When called for the first time, the code generates test-ASY.pdf file and
includes it. After the second call, a new test-ASY.pdf is generated.
ConTeXt generates an error because the name of the files is the same, but
the content is not.
There should be an option for \externalfigure to disable this check, but I
couldn't find it. Here is an alternative approach, that changes the name
of the PDF.
\usemodule[filter]
\unprotect
\appendtoks
\setuevalue{set\currentexternalfilter
buffer}{\externalfilter@set[\currentexternalfilter]}%
\to \everydefineexternalfilter
\unexpanded\def\externalfilter@set
{\dodoubleargument\externalfiter@set_indeed}
\starttexdefinition externalfiter@set_indeed [#1][#2]#3
% #1 = filter
% #2 = options
\begingroup
\edef\currentexternalfilter{#1}
\setupexternalfilter[#1][\c!name=,#2]
\externalfilter@set_filenames
\setbuffer[\externalfilter@buffer_name]#3\endbuffer
\externalfilter@process_filter
\stoptexdefinition
\protect
\defineexternalfilter
[MARKDOWN]
[
filtercommand={pandoc -f markdown -t context
\externalfilterinputfile\space -o \externalfilteroutputfile},
cache=yes,
purge=no,
]
\define[1]\NEW
{\setMARKDOWNbuffer{This is #1}}
\traceexternalfilters
\starttext
\startMARKDOWN
This is **one**
\stopMARKDOWN
\NEW{**ONE**}
\NEW{_TWO_}
\stoptext
Note that this has the same limitation as using \type{...}. The contents of
\NEW{...} must have matched braces. If this works, I can include the code in
t-filter (mkiv only, as I no longer want to maintain the mkii branch).
