selectWord/selectParagraph when selection is at the end of the content

[barnettben]

Double/triple-clicking to select a word/line works the same way as NSTextView, except when the clicks happen at or past the end of the content.

If you triple-click in the whitespace beyond the end of any text content, the first click moves the insertion point to the end, but the next two clicks don't highlight the final word/line.

It looks like textSelection(for:enclosing:) doesn't work properly when the insertion point is at the end of the text content. It just keeps the same selection.

I've got a proposed solution, but it's a bit annoying:

In selectWord/selectParagraph/selectLine, we could detect if the current selection is at the end, and if so, move it back a character before trying to select the word/paragraph/line.

I've done a quick experiment, and the behaviour does seem better. Would you be interested in a PR with this workaround?

Thank you for bringing that to my attention.

I just notice that while it is indeed just like you described in the NSTextView (and TextEdit), the Xcode editor behaves differently (like STTextView):

Hi, thanks for taking a look. I'm sorry, I don't think I worded the description quite right. I was trying to describe clicking in the space below the last line of any content. I've made a recording from TextEdit. Xcode does behave a bit differently here too, because it always adds a trailing newline.

(Your reply was the first notification that came in just as I woke the computer, so a quick reply!)

yes, the NSTextView (and TextEdit) seems to behave differently from the TextKit2 selection. It seems this is unique behavior to the mouse selection (tap to select), because keyboard selection selects the newline character

Fixed (changed) in 2.2.5

Thank you, that's working great :)
