Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

What is your favorite programming language?
My language, obviously.
- Bamless/jstar: A lightweight embeddable scripting language

Implementing a Call Stack
Also, since you are willing to look at non-treewalk interpreters, you can take a look at this: https://github.com/bamless/jstar/blob/master/src/vm.h In this I use two parallel arrays, one for frames and one for variables. The frame contains the instruction pointer of the function and the address of the start of the activation record. Variables are stored packed inside the stack array and are accessed through indexing.

Implementing a Call Stack
Here you go: https://github.com/bamless/interpreter. Look at the interpret/memenv package. The implementation really couldn't be more simple: it is just a queue of frame objects. pushStackFrame is called when calling a function, and popStackFrame when hitting a return or a function end. The MemoryEnvironment is instantiated by the interpreter visitor so all parts of it have access to the memory. The variables themselves are kept in an hashmap inside each Frame. Not the most efficient way but fast enough for a tree walking interpreter
