When using \input{...} inside an \edef the first token<br>
in the file disappears:<br>
<br>
\directlua{\unexpanded{%<br>
out = io.open('testfile.tex','w')<br>
out:write('hello\\noexpand')<br>
io.close(out)}}<br>
\edef\tmpa{\input{testfile.tex}}\show\tmpa<br>
% > \tmpa=macro:<br>
% ello<br>
\bye<br>
<br>
For some reason, it gets worse if the file starts<br>
with \noexpand\something:<br>
<br>
\directlua{\unexpanded{%<br>
out = io.open('testfile.tex','w')<br>
out:write('\\noexpand\\hello\\noexpand')<br>
io.close(out)}}<br>
\edef\tmpa{\input{testfile.tex}}\show\tmpa<br>
% > \tmpa=macro:<br>
% <gibberish><br>
\bye<br>
<br>
If I use \edef\tmpa{\input testfile.tex } instead, both<br>
examples work as expected.<br></blockquote><div><br></div><div>confirmed, thank you for the report.</div><div><br></div><div> </div></div>-- <br><div dir="ltr" class="gmail_signature">luigi<br></div></div>
