I'm writing a TeX-noweb document. I compile it with
noweave -tex -filter "elide comment" texcode.nw > documentation.tex
but when I try to compile the resulting file with
xetex -halt-on-error documentation.tex
I obtain the following error message
! Undefined control sequence.
<argument> ...on}\endmoddef \nwstartdeflinemarkup
\nwenddeflinemarkup
It seems that `\nwenddeflinemarkup` is not recognized. If i delete from the document all the sequences
\nwstartdeflinemarkup\nwenddeflinemarkup
the document compile without exceptions.
What can be the problem?

It may have been a long time since anyone used noweb with plain TeX and not latex. Send me a short .nw file that exhibits the problem and I'll see if I can reproduce it.

Now comes a short test file (atest.nw), commands in the terminal, the derived file doc.tex, the xetex command in the terminal, the final file doc.log with the error message "Undefined control sequence."

Hi Norman.
Sifting through the code I found that \nwstartdeflinemarkup and \nwenddeflinemarkup are defined in noweb.sty (LaTeX support for noweb) but not in nwmac.tex (plain TeX support for noweb).
If i call noweave with the option "-tex" it wraps the noweb code into a TeX casing with a "\input nwmac.tex" as first instruction.
Maybe this is the root of the problem.
Regards.
