Nooooooooooooo! 

Actually... I have tried and failed many times and it doesn't play well with the languages I code it, so I had to let it go.  

 What languages don't play well with Emacs? 

 Java, just to name one of the popular ones. The debugger is a complete joke. 

 Ah, yes, well Emacs is not a debugger.  It's an editor.  But for Java I use IntelliJ -- mostly. 

 ... PHP... 
But, I'm not blaming emacs. 

 Opposite experience here!
