Dear list, I have the following sample: \starttext \ctxlua{ context.setvariable("environment", "filename", "abc123") } \ctxlua{ c = context.getvariable("environment", "filename") or "a" } \ctxlua{ d = [[\env{filename}]] } c: \cldcontext{c}\\ \doifelse{\cldcontext{c:match("\letterpercent d+")}} {123}{yes}{no}\\ d: \cldcontext{d}\\ \doifelse{\cldcontext{d:match("\letterpercent d+")}} {123}{yes}{no} \stoptext Which is the Lua equivalent of \getvariable{}{}? I get nil now. BTW, I wonder why \setvariable prints the variable, botn in Lua and ConTeXt. Many thanks for your help, Pablo -- http://www.ousia.tk
