Copy, with line wrapping!

If you've been trying to copy/paste text from a multi-pane tmux session with the mouse, you've probably been pretty pissed at the blissful ignorance a terminal application has of the rodent in your hand.

The alternative, which is quote-unqoute native copy/pasting using copy-mode takes a bit to get used to. So this is one solution for copying and pasting lines from a session with correct line wrapping behaviour, albeit keyboard only.

Disclaimer

Since copy-mode has similar concepts of marks, regions, and temp buffers to Emacs .. you'll probably find it straight forward if you're familar with Emacsen. For people using vi-mode in tmux, the same still applies but obviously the default key bindings will differ alot from what I show below.

  # UGLY
  def self.starts_with(*strings)
    # Big loop to build something like this...
    where("wording LIKE ? OR wording LIKE ? OR wording LIKE ?", 'blah%', 'blaah%', 'blaaah%')
  end

  # PURDY
  def self.starts_with(*strings)
    strings = strings.map { |s| s+'%' }

-- The MySQL docs say COALESCE() "returns the first non-NULL value in the list,

-- If the value to be returned is an integer, COALESCE() first casts it to
-- the type of a subsequent non-NULL argument. ಠ_ಠ
