That way we can keep our magenta codes separate from the compiler logic. So lets put our Magenta codes in a file called code.m. Okay but having codes in a string variable is not that fun. class Magenta `)Īnd would you look at that - we already have a working language! Let me start by creating an index.js file and set things up. I am going to use Node.js but you can use any language to follow along, the concept will remain the same. Our simple programming language creates a codes variable that contains text that gets printed to the console… in magenta, of course. Want to give it a try? Let’s create a super simple programming language together that outputs magenta-colored output in the console.
InterpreterĪn interpreter goes through the program line by line and executes each command. CompilerĪ compiler converts codes into machine code that the processor can execute (e.g. So we can simply define some rules, then, to make it work, we can use any existing programming language to make a program that can understand those rules, which will be our interpreter. And those things are compilers, interpreters, etc. And to make them useful, you need something that understands those rules. In short, a programming language is just a set of predefined rules. But have you ever wondered how you could create your own programming language? And by that, I mean:Ī programming language is any set of rules that convert strings to various kinds of machine code output. By now, you are probably familiar with one or more programming languages.
