--- Perfect backslash(\) for Mac JIS keybord users

-- The problem:
--   On Mac, Japanese IME setting to replace Yen-backslash is ignored by
--   IntelliJ, jEdit or such as because JVM uses another keymap traditionally.

-- Solution:
--   Use Hammerspoon (http://www.hammerspoon.org/) instead of Japanese IME
--   setting. Paste below to your ~/.hammerspoon/init.lua file.
