I think there is a bug in the (latest) beta that was not there earlier this year. In particular, it worked (and still works) in the version current version: 2014.03.19 23:11 but it show *no* line numbers at all in the (latest) beta: current version: 2014.07.30 10:31 A minimal example follows: \usemodule[vim] \setupvimtyping[% numbering=yes,% numberdistance=2em] \definevimtyping[cpp][syntax=cpp] \starttext \startcpp #include <iostream> int main() { std::cout << "Hello, world!" << std::endl; } \stopcpp \stoptext Sadly, I'm not a ConTeXt nor a lua expert so maybe anybody can help? Regards, Günter p.s.: BTW, I still could not resolve the bug with integrating tikz but I verified that it works with the stated version above (2014.03.19 23:11) on my system (nothing else changed).
