[![HitCount](http://hits.dwyl.io/njbrown/loris.svg)](https://hits.dwyl.io/njbrown/loris)

Easy scripting in C++.

## Features

*	Simple and familiar syntax

*	Object Oriented

*	Auto-binding of c++ functions to Loris

*	Mark and Sweep Garbage Collection

*	Easy to embed in c++ applications

*	Easy to extend

## Future Features

* 	Pre-compilation

## Example Usage

	#include "loris/loris.hpp"

	double multiply(double a, double b)

	{

		return a * b;

	}

	int main()

	{

		loris::Loris loris;

		loris.AddSource(R"(

		def hello()

		{

			return multiply(5, 10);			

		}

		)");

		loris.AddFunction("multiply", loris::Def(multiply));

		loris.Compile();

		double result = loris.ExecuteFunction("hello");

	}

## Example Script

	//class named Hello

	class Hello

	{

		//constructor

		Hello()

		{

			print("this is a constructor");

		}

		

		//member function

		def Greet()

		{

			//call print function

			print("hello world!");

		}

	}

	def main()

	{

		var hello = new Hello();

		hello.Greet();

	}

## Syntax

## Known Issues

* `or` and `and` statements are parsed but the bytecode isn't generated and will cause errors if used

* garbage collection sometimes causes random crashes
