Thanks for reply I would ask only one more thing, mobDebug is a library aside, there is a way I can only use this function'' step in'' on a button that I have in my interface without me having to redeploy it? My entire interface was built in WxLua and I have a button called '' step in'' and I need him to do just that, run command lines starting from a hook.

To answer your question, these commands work this way: the debugger sets a line hook (using debug.sethook command), which then keeps track of where in the script is the execution. When you run "step in" command, it sets a flag to stop at the very next command. The hook then checks for that flag (https://github.com/pkulchenko/ZeroBraneStudio/blob/master/lualibs/mobdebug/mobdebug.lua#L514-L520; the variable is step_into) and if it's set, it suspends the debugging at that step. "step out" is a bit more complex, but works in a similar way. When the command is executed, the debugging keeps the current position in the stack and only stops when the position in the stack is current-1. It applies some logic to "fix" stack calculations in some cases and to make it work for Lua and LuaJIT interpreters (see the explanation here: https://github.com/pkulchenko/ZeroBraneStudio/blob/master/lualibs/mobdebug/mobdebug.lua#L451-L462). It also checks for whether this code is running in a separate coroutine as coroutines have their own stack. Paul.
