Subject: The odd semantics of \begincsname
Date: Sat, 17 Aug 2019 19:19:48 +1200 [thread overview]
Message-ID: <3c6496fd-2dc7-4bd9-1c72-74eaa5b7ae02@gmail.com> (raw)
Dear list,
According to the LuaTeX documentation:
“The \begincsname primitive is like \csname but doesn’t create a
relaxed equivalent when there is no such name.”
I thought it would be possible to use this fact to skip the \relax-ed
definition when \def-ining a new control sequence, but the following MWE
fails with \inaccessible:
\expandafter\gdef\csname yes\endcsname{}
\expandafter\gdef\begincsname no\endcsname{}
\bye
Is this a bug or is this behaviour intended? Could this be fixed by
making manufacture_csname aware whether it is in a def_cmd context or
not?
Cheers, Henri
