"levi" general purpose scripting language

Yes, Yet another scripting language. Currently it's just run-time interpreter, however It's on-going project and there are plans to add virtual machine so parser backend will be translating to native bytcode. But at least for now it is working as fair interpreter.

Following supported

• expressions
• functions definions, function calls
• if/while statements
• classes ( member function )
• comments

Usage

./bin/levi <filename>

Examples

Hanoi Game

function Hanoi(var m, var a, var b, var c) {
  moves++;
  if(m == 1){
    print << m << " from " << a << " to " << c << endl;
  }else{  
    Hanoi(m-1, a,c,b);
    cout << "Move disc " << m << " from " << a << " to " << c << endl;
    Hanoi(m-1,b,a,c);
  }
}

function main(){
  var discs = 4;
  var result = Hanoi(discs, 'A', 'B', 'C');
  print result;
}

Calculate fibonacii

function fibonacci(n)
{
        if (n <= 1) return n;
        return fibonacci(n - 2) + fibonacci(n - 1);
}
print fibonacci(20);

CPP API

In parallel we've started to work on providing cpp API to connect LEVI from cpp itself. but it's experimental

#include <integ/levi_interp.hpp>

int main(int argc, char** argv)
{
	LeviInterpreter levi;

	levi.execute("function fibonacci(n)				      "
	"{												                      "
  "    if (n <= 1) return n;						          "
  "    return fibonacci(n - 2) + fibonacci(n - 1);"
	"}                                              "
	"                                               "
	"print fibonacci(20);                           ");

}
