Because Zero Brane Studio is written in Lua and is cross-platform, it can't automatically hook into an interpreter like LuaEdit or Decoda can. Instead, Zero Brane's debug facilities rely on a Luamodule, much like debug.lua discussed earlier in this chapter. To enable debugging in Zero Brane Studio, you need to include the following line of code at the start of your program:

require("mobdebug").start()

Breakpoints will not work until that code is executed. After that line of code has executed, you should be able to debug in Zero Brane using tools similar to those provided by LuaEdit and Decoda.
