Sadly we cannot have the two together. So I started to do an analysis of the situation. OCompletion includes physically ECompletion. So what I plan to do in the coming months is: - make ECompletion working in 1.4 (Alain I need your help with caret, isCaretBehindChar, selectionPosition:, wordAtCaret) - analyze the extensions made by each package and move the extension that make sense into their respective packages For example E/OCompletion extends Shout with some simple queries, String and other so I will make a list of changes that we should move to the right places. - understand how we can make sure that OCompletion does not just include the code of ECompletion. - understand how to extend Ecompletion to get OCompletion and both working.
