Consider the following:
\catcode`\{=1\catcode`\}=2
\directlua{token.set_macro("foo", [[foo\ foo]])}
\show\foo
\toks0\expandafter{\foo}\end
> \foo=macro:
->fooBAD foo.
l.5 \show\foo
?
)
Runaway text?
fooBAD foo} \par \end
! File ended while scanning text of \toks.
<inserted text>
}
set_macro needs to check if the space is the only characterafter a backslash
before removing a "trailing" space. I attached a patch.
Thanks,
