# PreloadCounts
#
# Usage:
#   collection = Post.limit(10).preload_counts(:users)
#   collection.first.users.count  # fires one query to fetch all counts
#   collection[1].users.count     # uses the cached value
#   collection.last.users.count   # uses the cached value
#
# Call `::PreloadCounts.enable!` inside of an initializer to enable preloading of association counts

Delete all characters left of the cursor

⌘+←Delete Send Hex Codes:

• 0x18 0x7f – Less compatible, doesn't work in node and won't work in zsh by default, see below to fix zsh (bash/irb/pry should be fine), performs desired functionality when it does work.
• 0x15 – More compatible, but typical functionality is to delete the entire line rather than just the characters to the left of the cursor.

module EnumerableMatchers
  # RSpec already lets you do this:
  #
  #   arr.should be_any {|item| item["foo"] == 2 }
  #
  # However, that's kind of unwieldy to say. So we add this matcher so we
  # can say one of these alternatives instead:
  #
  #   arr.should have_any {|item| item["foo"] == 2 }
  #   arr.should have_an  {|item| item["foo"] == 2 }
