ZeroBrane Studio provides local, remote and cross-platform debugging for applications executing Lua code. The debugger supports the following functions: step through the code, set/remove breakpoints, inspect variables and expressions using the Watch window, inspect the call stack with local values and upvalues (local values defined in the outer ...
Function names are often of the form p.myFunctionName, where p is the table from the return p at the bottom of your program. The reason for this is that you can only access functions that are entries in this table from the original #invoke statement. Functions for local use within the program can have any name.
Marshalling data between C and Lua functions is also done using the stack. To call a Lua function, arguments are pushed onto the stack, and then the lua_call is used to call the actual function. When writing a C function to be directly called from Lua, the arguments are read from the stack. Here is an example of calling a Lua function from C:
function p. q is syntactic sugar for p ["q"] = function. function builds a function. It doesn't declare it. Functions are first-class objects and can be assigned to variables, placed in tables, serialized into strings, and deserialized back out again. Think interpreted, not compiled.
It is intended for use by other Lua modules, and should not be-- called from #invoke directly. local libraryUtil = require ('libraryUtil') local checkType = libraryUtil. checkType local arguments = {}-- Generate four different tidyVal functions, so that we don't have to check the-- options every time we call it. local function tidyValDefault ...

The functions of the Module:SimpleDebug can be used for cases such as those mentioned above or for more complex cases: When variables or the returned value (or values) by a function are local. To see if the flow of the program goes through a point (to which you will label).
