HI,

I see kscreendoctor can output in JSON. The default output also gives me colours, which helps with readability - nice job on that.

However, it would be nice to be able to provide commands to change the current configuration in JSON/YAML/ any other standard format as desired aswell. This helps to make it easier to interoperate with other tools in scripting pipelines, and also, whilst the format has already been fixed and so shouldn't be removed for compatibility reasons, overall it seems better to leverage an existing language for structured data rather than inventing a new one. The program has to have a custom parser written to operate with data given to it, and then I also have to figure things out for casual use, or do the same and operate over text if I want to script things for any reason.

I am thinking of something like this sort of syntax:
`kscreen-doctor '{"outputs": [ "1": {"primary": true}  ] }'`
for the equivalent of
`kscreen-doctor output.1.primary`

The existing form is already JSON-like and may mix well in some way - e.g. how `jq` and similar tool extend the syntax a bit to give ways to set values in an elegant way. There may be a way to blend the two.
