Create Javascript Debugger

I want to create my own javascrip debugger 开发者_运维问答using V8 debugger in eclipse. But i am not getting any document about the V8 debugger or any Source code for v8 debugger. i have my own browser. i want to create one Javascript debugger which debug the .js code remotely. And same debugger i want connet with my own browser. So what can i use for creating debugger in eclipse. can i use v8 debugger as base for my debugger or any other idea i have to use for that.

Thanks for your support

Just out of curiosity - why reinvent the bicycle? FireBug has arguably the best free javascript debugger available
