Hello all,
how to call \let from within Lua?
I'd need to "\let\T=4" using Lua.
The following code doesn't work (not so surprisingly):
----
\startluacode
a = 4
\stopluacode
\expandafter\let\expandafter\T=\cldcontext{a}
\starttext
Test \T.
\stoptext
----
What's the correct way?
why let and not context.setvalue("T","4")
anyway ...
\startluacode
a = 4
\stopluacode
\normalexpanded{\let\noexpand\T\cldcontext{a}}
\starttext
Test \T.
\stoptext
You need more \expandafter because \cldcontext needs two expansion steps:
\expandafter\expandafter\expandafter\let\expandafter\expandafter\expandafter\T\expandafter\expandafter\expandafter=\cldcontext{a}
but I wonder why you don use \def or \edef:
\edef\T{\cldcontext{a}}
... OK, thank you, Hans & Wolfgang, for your responses.
Best regards
Lukas
