  6. This Kaylee plugin can be used to perform the job of `Blather
  7. <https://gitlab.com/jezra/blather>`__. Its configuration is of the
  8. following format::
  9. ".shell": {
  10. "VOICE_COMMAND": "SHELL_COMMAND",
  11. ...
  12. }
  13. A VOICE_COMMAND may contain any number of the special word ``%d``,
  14. which is a stand-in for a spoken number. The spoken number is
  15. transformed into a decimal integer which may be substituted into the
  16. SHELL_COMMAND any number of times. These substitutions are made by
  17. writing ``{INDEX}`` in the SHELL_COMMAND, where INDEX is an integer
  18. counting the ``%d`` strings from 0. An example of this type of command
  19. is::
  20. "%d is a number": "echo 'the number you said was {0}'"
