In Ruby, is there a way to print out all the Global variables and Constants defined / predefined?
The
global_variablesmethod returns an array of all global variable names. To get the names of all the constants defined in a module, sendconstantsto the relevant module. For example, to get all the constants that you can access without specifying a namespace, useObject.constants.
