Question

I’m dynamically defining a module name from an argument passed on the cli, for example Required::Module::#{ARGV.first}

Is there any way to check if that module exists? Also, how would I run methods on it not knowing it’s exact name?

Answer 1

Check for module existence using the const_get method:

begin
    mod = Required::Module::const_get "ModuleName"
    #It exists
rescue NameError
    #Doesn't exist
end
