I have a "bubble mm Sutra" with various tips on bubble mm, such as the steps to eat western food and the methods to watch movies. When I am dating mm, I only need to create an interpreter, run the script above.

Interpreter mode:

Given a language, the interpreter mode can define a representation of its syntax and provide an interpreter at the same time. The client can use this interpreter to explain sentences in this language. The interpreter mode describes how to explain these statements with a simple syntax. The language mentioned in the interpreter mode refers to any combination that any interpreter object can interpret. In the interpreter mode, you need to define a hierarchical structure of a command class that represents grammar, that is, a series of combination rules. Each command object has an interpretation method, which represents an interpretation of the command object. Any permutation and combination of objects in the hierarchical structure of command objects is a language.
