Create a CLI executable

[jon-dez]

Provide an executable that could be run from the command line. This would require refactoring the source code to separate the UI from the logic that should be shared with the CLI.

Interesting, if you describe commands an options we can start with a skeleton and fill the logic later.

An essential use of this app is to setup joycons if you change skin or replace motherboard, how cli will support that? Some ascii art would be awesome anyway

So far I can think of the following commands:

scan

Scan via bluetooth to find available controllers for pairing

sub commands: none

options:

--interval <seconds = 5> - Do a scan every given seconds (default 5)

connect <mac address>

Connect to a controller via bluetooth

sub command: none

options:

--timeout <seconds = 5> - Cancel the connection if the controller isn't found (default 5). Pass 0 for no cancelation.

list

List the currently connected controllers via bluetooth or usb.

options:

--text - Doesn't output ascii art

sub commands:

bluetooth or bt - list bluetooth controllers
usb - list usb controllers

modify

Change a controller

sub commands:

color <value>

options:

--controller|-c <mac address>

Example:

jc-tool modify -c 00:00:00:00:00:00 color "neon blue"

jc-tool will have an internal mapping of the color value for "neon blue" so it will know the actual value to send. If there is no internal mapping then jc-tool will attempt to parse it as a hex color value.

Maybe we should print the old and new color values as well?

I think list and modify will probably be what most people will use if they already have connected their controllers, so we could hold off on scan and connect since these are already provided by the OS. Also, I like the idea of ascii art, especially for the list command.
