Hello,
is it possible to use a block of context code depending on a value of a Lua variable?
I tried something like:
---
\starttext
\directlua{test = true}
%\directlua{test = 5}
%\directlua{test = "a"}
\doifempty{\directlua{return test}}
%\doifempty{\directlua{test}}
{Yes}
{No}
\stoptext
---
But this gives me always "No".
- I'm not sure if this is a good way, and whether attempt to use \doif(...) macro is a good idea at all.
Any (better) solution?
Best regards,
Lukas

\starttext
\ctxlua{test = true}
Test is \ctxlua{commands.testcase(test)}{True}{False}.
\ctxlua{test = false}
Test is \ctxlua{commands.testcase(test)}{True}{False}.
\stoptext
