Support settings sections with | operator

[captain0xff]

The roslyn lsp server (https://github.com/dotnet/roslyn) uses the | symbol to separate settings levels (like csharp|completion.dotnet_show_completion_items_from_unimported_namespaces). The sublime lsp client doesn't seem to support this. It will be nice if we can have a customizable approach here so that new operators can be easily added.

I think this should be doable with ST's score_selector.

Could you explain what in particular is not supported?

I don't think there is anything needed to be done here. This syntax seems to be used for the section names in workspace/configuration. We are able to split on dots if the requested section is a sub-path https://github.com/sublimelsp/LSP/blob/9be040dfc9d6bad3a7d4bb7c41f94f74ac4f0003/plugin/core/collections.py#L45 but in general the section names can be arbitrary strings.

So you should be able to just put those setting names into your config:

{
  "clients": {
    "roslyn": {
      // ...
      "settings": {
        "csharp|completion.dotnet_show_completion_items_from_unimported_namespaces": true,
        "csharp|symbol_search.dotnet_search_reference_assemblies": "somevalue",
        // ...
      }
    }
  }
}

From your logs provided in the other issue I can see that you already specified one setting with value "fullSolution" and it gets successfully returned in the response:
