Boomslang

How to run

• Clone the project
• cd Boomslang/app/
• make
• ./interpreter program (examples see below)

Features

1. Types
   • int
   • bool
   • string
   • void
   • fun(type_1, type_2, ..., type_n -> returnType)
2. Variables, final variables, functional variables
3. Overshadow variables
4. Basic arithmetics (Add/Sub, Mul/Div, Mod, Comparisons)
5. Assignment
6. if, else conditional blocks
7. while loop (break, continue, return early form function)
8. For loop (iterator is const, return early from function)
9. Functions
   • Recursion supported
   • Nested functions
   • Lambdas with recursion
   • Closure
10. Runtime error handling

Program examples

int factorial(int a) {
	int r = 1;

	while (a > 0) {
	  r = r * a;
	  a = a - 1;
	}

	return r;
}

void main() {
    // 5 factorial is 120
    print("Factorial of 5 is " + factorial(5));
}

void testReturnInFor() {
    for (int i = 0 to 50) {
        if (i == 5) {
            return;
        }
        print(i);
    }
}

void main() {
    testReturnInFor();
}
