[Bug 1585797] Re: Distinguish between input method "XIM" and "none"

[Brian Murray]

I don't know if the order of inputMethods matters, but none will always
be at the end with the following change.

 35      def getAvailableInputMethods(self):
 36 -        inputMethods = subprocess.check_output(['im-config', '-l']).decode().split()
 37 -        return sorted(inputMethods)
 38 +        inputMethods = sorted(subprocess.check_output(['im-config', '-l']).decode().split())
 39 +        inputMethods.append('none')
 40 +        return inputMethods

  Distinguish between input method "XIM" and "none"

Bug description:
  [Impact]

  language-selector-gnome includes a GUI to configure the input method
  via im-config. Besides the installed IM frameworks (IBus, Fcitx, etc.)
  the IM selector shows a "none" option, which actually represents the
  value "xim". This was an intentional simplification, made under the
  assumption that "none" and "xim" are approximately the same. However,
  it has proven to be an oversimplification. For example there is a need
  sometimes to control whether the X11 compose keys should be active or
  not.

  This SRU adds an explicit "XIM" option, and converts the "none" option
  to actually set "none".

  A recent reason why an explicit "none" option is needed is Ubuntu
  MATE, which does not install any IM framework by default for non-CJKV
  users. Currently, when such a user opens Language Support for the
  first time, the input method selector shows a blank value. With this
  SRU it will correctly show "none".

  [Test Case]

  An example test case would be:

  * Make a fresh install of Ubuntu MATE 16.04.
  * Open Language Support and find that the input method value is blank.

  [Regression Potential]

  Low. This won't *change* the input method setting, but the currently
  set value will be showed more correctly in some cases.
