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: <programlisting language="cpp" linenumbering="unnumbered"> int main() { return 0; } </programlisting> 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. Mojca

Does something like this work: https://wiki.contextgarden.net/Verbatim_XML Aditya

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: <programlisting language="cpp" linenumbering="unnumbered">// test.cpp: int main() { return 0; }</programlisting> 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 example, 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, frame=off, leftframe=on, rulethickness=2pt, framecolor=darkgray, width=local, offset=1ex]}, after={\stopframed\stopnarrow}] Hello \startprogramlisting[syntax=cpp,numbering=yes] int main() { return 0; } \stopprogramlisting Mojca

Hi,
Hans helped me out with some asciidoc processing a while ago.

(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)
Ad (a). The source that looks similar to this:
<programlisting language="cpp" linenumbering="unnumbered"> int main() { return 0; } </programlisting>
should be converted into some kind of equivalent of
% on top \usemodule[vim] \definevimtyping [CPP] [syntax=cpp]
\startCPP int main() { return 0; } \stopCPP
Any hints would be greatly appreciated.
This should get you pretty close: https://tex.stackexchange.com/a/652116/ You can look through the revision history for a few different versions if the newest one doesn't quite work. -- Max
