Ruby Compiler

Contains a tokenizer, a parser, and a code generator.

By the end, it successfully compiles some code in our language test.suvan , producing JavaScript output that we can execute.

While most compilers are highly optimized for speed, but ours will be optimized for easy readability and understanding.

Usage

In ./test.suvan:

make f (x,y)
    add(100, add(10,add(x,y)))
end

The above code will be compiled to:

function add(x,y){ return x + y};
function f(x,y){
        return add(100,add(10,add(x,y)))
}
console.log(f(1,2));

For now the compiler only supports the add function and the make keyword. The make keyword is used to define a function, and the add function is used to add two numbers. The end keyword is used to end the function definition.

Then once ruby has compiled the code, we pipe it to node to execute the JavaScript code.

Execution

To run the compiler, you can use the following command:

• Windows

ruby .\compiler.rb 

• Linux / mac

./compiler.rb | node

Then once ruby has compiled the code, we run the newly created file output.js to node to execute the JavaScript code.
