Hello,
How can I get the value of a variable or a mode in the lua part?
Example:
context --arguments=MyVar=true test
And in test.tex:
\starttext
\startluacode
local my_var = loadstring("return " .. get_value_of("MyVar"))
if my_var then
tex.print("TRUE")
else
tex.print("FALSE")
end
\stopluacode
\stoptext
TIA for any help!
Cheers, Peter

The solution is so simple... :
\ctxlua{userdata = userdata or {}; userdata.myvar = \env{MyVar}}
\starttext
\startluacode
if userdata.myvar then
tex.print("TRUE")
else
tex.print("FALSE")
end
\stopluacode
\stoptext
Cheers, Peter
