Many programmers or, programming enthusiasts, during their professional career, find themselves having to use various programming languages. It is often to exploit techniques and algorithms, sometimes even very sophisticated, for the resolution of problems that gradually arise. During this process, many of them ask themselves this question: “How to create your own programming language?<\/strong>“, Or, “What is hidden behind a command of any language?<\/strong>“.<\/p>\n\n\n\n

Before answering this question, we will try to understand how many types of programming languages exist.<\/p>\n\n\n\n

Today, we have two types of languages, there are compiled languages and interpreted languages. The difference is substantial, in compiled languages, the source code, that is our program, is converted into an executable file directly from the machine without the aid of any intermediate translation software. In interpreted languages, on the other hand, our source is not converted into an executable file but translated command by command and executed from time to time by an intermediate program called interpreter.<\/p>\n\n\n\n

In summary, we can say that compiled languages are converted by a software called a compiler, while the commands of an interpreted language are executed directly by a software called an interpreter.<\/p>\n\n\n\n

In this article I will explain how to create a programming language, specifically an interpreter, as it is “simpler and more immediate” than the design of a compiler, which would require not only a thorough knowledge of some very sophisticated tools, which we will see, but also a advanced knowledge of the type of processor that will have to execute the code.<\/p>\n\n\n\n

But what will you be able to do after reading this article? Well, you will understand the use of a Lexer and a Parser, how to program them up to designing your own command shell and creating one of the essential commands for any language: “the Print command”. In short, you will discover how to create commands, pass parameters to them and execute them within the command shell, which you will design and customize to your liking. Not only that, but you will also see how to execute these commands by saving them in a script and creating your own interpreter.<\/p>\n\n\n\n
