But it can be done sneakily …
% start demo
% previous line allows redefinition of ‘wrapup_run’
% to keep the code short, I use a direct definition of
% \idcode and \ctxlua. Nicer would be to store the desired
% output name in a lua variable and replace the
% \ctxlua with \startluacode … \stopluacode with
% a string.format inside it.
os.execute("cp \jobname.pdf doc-\idcode.pdf")
Hello from \idcode
% stop demo
