ANTLR

ANTLR is a computer program that helps people make other computer programs. It's kind of like a teacher who helps you learn how to speak a new language to talk to computers, but instead of teaching you the language, it makes the language for you.

In other words, it helps people create programming languages, which are like sets of words and rules that computers can understand. It's kind of like making your own secret code that only you and the computer can understand.

But why would people want to create their own programming languages? Well, sometimes it's easier to write programs in a language you create yourself, because it can be tailored to the specific task you want to accomplish. It can also make the code easier to read and understand.

ANTLR helps with this by allowing people to create what's called a "grammar" for their programming language. A grammar is like a recipe that tells the computer how to read and interpret the code written in your language.

So, with ANTLR, you can create your own programming language by writing a grammar for it. Once you've created the grammar, ANTLR can generate code that can understand and run programs written in that language. It's like having a really smart assistant who can take care of all the technical details for you.
