Yes, awesome, this does exactly what I want, thank you very much.
I used the following code:
\usemodule[vim]
% this breaks if directory doesn't exist before
\setupvimtyping[directory=output/]
% it would be potentially useful to have some predefined vimtyping
already present in the module
\definevimtyping
[programlisting]
[syntax=]
\startluacode
function xml.functions.processprogramlisting(t)
buffers.assign("listing","\\startprogramlisting[syntax=cpp]\n"
.. tostring(xml.text(t)) .. "\n\\stopprogramlisting")
context.getbuffer { "listing" }
end
\stopluacode
\startxmlsetups xml:programlisting
\pushcatcodetable
\setcatcodetable\ctxcatcodes
\xmlfunction{#1}{processprogramlisting}
\popcatcodetable
\stopxmlsetups
Now I need to get the "cpp" and "unnumbered" part processed
automatically, so that it will work for any language:
// test.cpp:
int main()
{
return 0;
}
which would then be transformed into
\startprogramlisting[syntax=cpp,numbering=no]
int main()
{
return 0;
}
\stopprogramlisting
For some reason the syntax highlighting doesn't work on the full
document, but it works inside the minimal example, so I still need to
investigate what's going on with the full document.
On an unrelated note:
I cannot make \startnarrow[middle=1cm] (or left=... for that matter)
produce any offset on the left. I was playing with the following
code, but the frame refuses to be shifted to the right
\setupvimtyping
[before={
\startnarrow[left=1cm,before={\blank[10pt]}]
\switchtobodyfont[8pt]
\startframed
[align=flushleft,
background=color,
backgroundcolor=gray,

This should get you pretty close:

You can look through the revision history for a few different versions if
the newest one doesn't quite work.

[NTG-context] How to do code listings & sections from XML (AsciiDoc)
Hi,
Hans helped me out with some asciidoc processing a while ago.
I played a bit further, but I'm currently facing two minor issues:
(a) I don't know how to turn program listing (verbatim code) from xml
to (perhaps, vim-based) syntax highlighting (but most importantly, to
make sure that line breaks work properly)
(b) some section titles are missing
Ad (a). The source that looks similar to this:
int main()
{
return 0;
}
should be converted into some kind of equivalent of
% on top
\usemodule[vim]
\definevimtyping [CPP] [syntax=cpp]
\startCPP
int main()
{
return 0;
}
\stopCPP
In the attachment I have the source document (test.adoc), the
generated docbook xml that should be further processed, and test.tex
that one processes to get the final pdf.
Any hints would be greatly appreciated.

return tex_formatted_error("nodes", "attempt to copy an impossible node %d", (int) p);
} else if (p lmt_node_memory_state.reserved lmt_node_memory_state.nodesizes[p] == 0) {
return tex_formatted_error("nodes", "attempt to copy a free %s node %d", get_node_name(node_type(p)), (int) p);

memcpy((void *) (lmt_node_memory_state.nodes + r), (void *) (lmt_node_memory_state.nodes + p), (sizeof(memoryword) * (unsigned) i));
if (tex_nodetype_is_complex(i)) {
