To do that you'd move it to emacs
@ OSGELD... to my silly eyes... I see WAY more commonality between Processing and Arduino than differences... so, while I understand that you do not... it leaves me confused that you feel that way.
Arduino's language heritage stands out clear to me.
And here's the crazy thought. Eclipse still won't make a majority of people happy... since editing environments are like candy... it seems everyone has a different favorite.
With small projects... the IDE doesn't bother me... maybe I'm unique in that.
When I'm working on a complex PDE file (or files), I just pull it all into my favorite customizable syntax highlighter editor app, I work on there... and then pass it back to the Arduino IDE and let it do the rest.
I can't say that ECLIPSE will be a welcome change for me. I've used it... and when decisions were being made for a JAVA editor... I selected NETBEANS instead of Eclipse... so maybe I'm just a little nutty.
