Hello all,
I'm looking for a way to insert any character (CSV separator) into a
variable. Manually insert a double (or single) quote is not a problem,
but how to use the universal way to not have to change the macro
definitions?
Is there another possibility to insert a macro parameter into a Lua
variable than the use double or single quote?
Any "universal" alternative is unfortunately impossible:
For example: \def\setseparatorC#1{\directlua{Sep=#1 }} ???
Thanx Jaroslav
Here is my minimal example:
\def\setseparatorA#1{\directlua{Sep="#1"}}
\def\setseparatorB#1{\directlua{Sep='#1'}}
\starttext
\setseparatorA{'} % OK
\directlua{tex.sprint(Sep)}
\setseparatorB{"} % OK
\directlua{tex.sprint(Sep)}
% BUT
\setseparatorA{"} % Error
\setseparatorB{'} % Error
\stoptext

Untested. Try
\unprotect
\def\setseparator#1{\directlua{sep=\!!bs#1\!!es}}
\protect

Hello Aditya,
I had no hope of solving the problem, but it works! Unbelievable!
Thanks very much for fixing the problem and the quickness too.
