Summary

In this chapter, you learnt about how to control execution flow using the when statements, conditional imports, selective includes, and so on. You also learnt how to use variables and facts to selectively skip routines and execute platform-specific subroutines. We refactored the MySQL role to start using dictionaries of variables to conditionally configure the MySQL server and to use more intelligent templates with prechecks for defined variables.

In the next chapter, we will begin exploring the second type of control structures, that is. iterative control structures, where we will start looping arrays and hashes.
