Xcode Source Editor Extension - single character selection range

Hey! Your code logic isn't right.

start.column is the offset of te cursor from the BEGGINING of the line, so column zero would be exactly the begining of the line, even if there are any spaces or tabs.

Column zero would be right before the first letter of this sentence.

So if you want to know if theres no selection you should instead check:

start.column == end.column // No selection

Or if you want to check for only one character or n number of characters selected you should do this:

start.column == (end.column - 1) // only one character selected
start.column == (end.column - x) // only X number of characters selected

BTW, I finished my xcode extension two days ago and I'm still not able to use it in Xcode 8 final because of a **** bug. 😠 but that's another problem.

Hope this helps 😉

Thank you for your reply!

Yes, you're right about how it should work. This is what i was saying, my code logic the same as yours.

The thing is it doesn't work this way, in your second example when i should get:

start.column == (end.column - 1) // only one character selected

what i really get from invocation is:

start.column == end.column // No selection

Can you confirm, please, that in your extension end.column is not equal to star.column when you have single character selected?

What version do you use? Xcode 8 or 8.1 beta? I should try 8.1.

Fixed in Xcode 8.1, thanks. (tested on beta 2)
