a small, educational AST interpreter that implements a dynamically-typed, C-like language.

main()
{
	var i = 5, x = 8;
	func1(ptr_test, &x);
	if i==5 {
		i+=2;
	}
	return i;
}

func1(f, x)
{
	f(x);
}

ptr_test(ref)
{
	@ref = 10;
}

fib(n)
{
	return n<2 ? n : fib(n-1) + fib(n-2);
}

• Basic Integer & Float Math (division not implemented yet).
• Function Calls (recursive is supported!).
• Pointers and pointer operations for passing variable by reference.
• Function Pointers.
• if-else conditional statements.
• while loops (implemented as for).
• return statements.
• Basic arithmetic ops like + - *.
• Basic bitwise ops like & | ^ << >>.
• Basic logical ops like && ||
• Basic comparison ops like != == < > <= >=.
• Basic variables which are dynamically typed and can be used with both integer, float, and pointer operations alike.
• Ignores C++ style // and C style /* */ comments.
• ternary operators
• Compound assignments like += -= *=
• Mixed integer and float expressions resolve to float
