Lemon

Lemon is a framework for building Javascript runtime software, built on the Chrome V8 Javascript Engine.

• C++ bindings

  Integrated support for javascript to c++ bindings and viceversa.

• Object oriented

  Lemon lets you build your applications with a simple and scalable object oriented approach.

• Single and multi threaded

  Lemon runs on a single thread by default but has support for running on multiple threads.

Example

A simple example of an application written in Lemon looks like this:

void App::Start(int argc, char* argv[]) {

	for (int i = 1; i < argc; ++i) {

		// Get filename of the javascript file to run
		const char* filename = argv[i];

		// Create a new context for executing javascript code
		Local<Context> context = this->CreateLocalContext();

		// Enter the new context
		Context::Scope contextscope(context);

		// Run the javascript file
		this->RunJsFromFile(filename);

	}

}

You can find this example in the 'app' folder, in the file App.cpp.

The example does the following:

1. Calls the Start method which automatically starts the application inside a virtual machine.
2. Loops each argument given from a command line, each argument is expected to be a javascript file.
3. Creates a new context and enters the context.
4. Calls the RunJsFromFile method which executes the code inside a Javascript file.

A context is an execution environment that allows Javascript to be executed inside the virtual machine.
