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

2011-03-25 Thread Procházka Lukáš Ing . - Pontex s . r . o . 

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
