Re: [NTG-context] \doif... and Lua

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?

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