A simple hello world NPAPI plugin for Google Chrome?

Question

I am trying to make a chrome plugin but Chrome API doesn't give me enough power. I want to use NPAPI but I have no idea how to use it but I do have experience in Visual C++.

Can someone show me a 'Hello world' in C++ application so I can get started?

Answer 1

NPAPI plugins shouldn't be browser specific (at least as far as possible). Seamonkeys npruntime sample can be considered a basic Hello World for NPAPI. If you care about up-to-date Mac support, you need to take a look at WebKits or Apples samples.

Reading material to get you started:

• Building a FireFox plugin - 3 part introduction to NPAPI
• Gecko Plugin API reference - NPAPI documentation at MDC
• Mac specific info on MDC

There is also the FireBreath project: It is a framework aiming at lowering the entry barrier to browser plugin development and already takes care of most common tasks and issues.
