I'm new to processing but I'm using arduino IDE for over one year , wrote many projects to arduino. a week ago I downloaded the source code of processing and read some files of it as I want to participate with some ideas in PDE.
my idea was to support autocomplete dialog in the PDE , but I don't know how to implement it - as a tool or as a core library - ?
this idea will be part of my graduation project this year + some modifications in the serial library that will be this issue https://github.com/processing/processing/issues/1374

so any hints due to the autocomplete idea ?
