How to represent arrays contents in plugin definitions?

Is there a more detailed way to define the plugin settings when theyre arrays/objects? I’m thinking of something like tap-csv that has a list of file definitions and the definition on the hub just assigns it as an array and describes the nested structured of each element in the description. Is there a way to describe these in more detail?

I know we already have the dot syntax for object like setting.sub_setting but is there a way to do that for arrays?

"setting": {
   "sub_setting": "x"
}

Like files.0.setting.sub_setting?

"files": [
  {
    "setting": {
         "sub_setting": "x"
      }
  }
]

I’m not sure if something like this already exists or if we would even want it if not but wanted to check. This was following a discussion in office hours about more detailed settings definitions.

Seems like we should be able to do setting[n].sub_setting.

@tayloramurphy @pnadolny13 Yeah, that can be done. Shouldn’t be difficult. We cannot, however, have an attribute name that starts with a digit*.

*Unless we’re being very pedantic, in which case I’d clarify that though we can have such an attribute, we wouldn’t be able to access it with the normal dot notation.
