How do you write an interpreter language?

To create an interpreter first you need to create a lexer to get the tokens of your input program. Next you create a parser that takes those tokens and, by following the rules of a formal grammar, returns an AST of your input program. Finally, the interpreter takes that AST and interprets it in some way.
