I am new to creating plugins. I want to create an eclipse plugin for a new scripting language. And, its syntax is quite similar to JavaScript. So, I wish to extend existing Javascript plugin that exists in eclipse.
Please suggest how do I go about it. Mainly, I want to have editor functionality (syntax checking, auto completion and ctrl-click to go to hop across functions), no compiler/build is needed.
Also, where do I find the source code for existing JavaScript plugin.
