Style by coding (YAML, ...)

[klokan]

At SOTM we have discussed a need to be able to write the style by hand as well...

There is the @tmcw codeflow project which demonstrates such approach with YAML, TOML and JSON5 syntax for the GL JSON format.

Details in:

The code:

I agree, this would be helpful for styling attributes not yet supported by the graphical editor. YAML would be my first choice since it is more compact than JSON.

I think this has been adressed with both the JSON editor within Maputnik in each layer and
the possibility to edit a JSON locally and have it sync up with Maputnik.
