Hi Joseph,
last year you helped fixing a strange lgrind.dtx file:

You send a simple patch, and that worked all nicely till TeX Live 2021,
and now the same lgrind.dtx (patched version is attached) fails again.
The error message is comes from this part of the code:
% The meta-symbols and their meanings are:
% \begin{description}
% \item[\$] The end of a line
% \item[\^] The beginning of a line
% \item[$\backslash$d] A delimiter (space, tab, newline, start of line)
% \item[$\backslash$a] Matches any string of symbols (like `.*' in lex)
***
And the error is:
[8]
! Missing } inserted.
}
l.540 % \item[\^]
The beginning of a line
? X
Any suggestion again? As said, it was working till Dezember 2020 ;-)
All the best
Norbert

Ciao

The structure of the .dtx is ... unusual. It's got the \begin{document}
in the 'input' stage and the \end{document} 'as normal'. The result is
"%" ends up with the 'wrong' catcode, which is where the issue arises:
what should be a comment in the .def is not any longer. It can be fixed
by making the .dtx 'normal', i.e. moving the \begin{document} line, but
I'm not sure if that is an acceptable fix.
