dot-symbol in config-key

[gabor]

i'm trying to convert the following code from config.cson to .proton:

".js.source":
  editor:
    tabLength: 2

i tried to simply do

[".js.source.editor.tabLength" 2]

but proton uses . to split the key it seems, so it becomes

  ""
    js:
      source:
        editor:
          tabLength: 2

any ideas what to do here? is there perhaps a way to escape the . ?

I have this in my ~/.proton

["editor.tabLength" 2 {:scopeSelector [".source.ruby" ".source.coffee" ".text.tex" ".source.cpp", ".text.html"]}]

which ends up like this in my ~/.atom/config.cson

".coffee.source":
  editor:
    tabLength: 2
".cpp.source":
  editor:
    tabLength: 2
".html.text":
  editor:
    tabLength: 2
".ruby.source":
  editor:
    tabLength: 2
".tex.text":
  editor:
    tabLength: 2

thank you, it works well.
i have to specify it twice, like this:
(i want it to default to 4, and be 2 for javascript)

    ["editor.tabLength" "4"]
    ["editor.tabLength" "2" {:scopeSelector [".js.source"]}]

i was not sure if it will work, but it worked fine. maybe the manual could also have an example where it is used multiple times?
