See thread in openapi forum.

hello people,

I am new to the Idea plugins .In fact I have just started using the Idea. I have programmed a plugin for eclipse to create classes after you have created a java project by using java project wizard built-in eclipse. My requirements for Idea are ---

1) Access all information about the open java projects. like source folder names , packages and all the compilation units.
2) Create a wizard to take input from the user about file names etc
3) open an editor programatically where I wil show auto_generated codes.

Please help me with relevant info may be the links or resources where I should find the APIs to do it.

and how different is it from eclipse I mean are there extension points etc

Thanks in advance !!!

yeah I saw that but it was too late anyways thank you for your reply I hope it gets me a good start
