1 - Because this project
After a long time studying, testing and creating interpreters and compilers, I get acceptable level in the subject, after a while I created languages and projects that caught the attention of some people and of course beginners who wanted to learn how to create their languages and after teaching several people and more and more people asking me, I decided to create this "manual" gathering all my knowledge and teaching to beginner developers who have doubts and even those who are at university and want a project to impress their teacher and their class.
2 - Why should I learn to create languages?
While large languages need a team working on them to always get better, you can use that knowledge and create a language that makes your job and your friends' jobs easier. Why not create a language with a specific focus that helps you at work?
Furthermore, for every programmer, it is of paramount importance to understand how languages work inside them.
3 - What languages are we going to use and what do I need to know?
## What language?
We're going to use Python, which isn't that fast, but it's easy and we can teach most of the concepts without worrying about more complex syntaxes like C and Java.
## What do I need to know?
- Of course, the basics of
Python and C
(don't worry, python is similar to C and if you want to implement in C surely if you know C you'll be able to write the code!)- Desirable to know how to read text files
4 - What will I learn?
You will learn 3 important parts:
- Theory, here you learn how a language works
- Creating a interpreter, here you create an interpreter that reads the code and executes
- Creating a Compiler, Create a compiler that generates C code and call the C compiler to generate an executable
- Comparison, comparing a compiler for assembly code to a compiler for C code
5 - Now what?
And now you're going to read this tutorial and finally understand how a language works and create your own languages!
And it's important to note that the compilers that we're going to look at here won't be 100% optimized because it would be a great job for you, but I'll try to write something about optimization.
