Whitespace treatment in grammar

[OlegIlyenko]

Please correct me if I missed it in the spec, but I haven't found a formal definition of the whitespace treatment combined with some of the tokens. For example in the detective definition. It's not 100% clear whether whitespace is allowed between @ and Name. The same is for the variable: can I put a whitespace between $ and the Name like this?

$ myVariable

Intuition tells me that in most cases whitespaces are allowed, so query like this:

query    , FetchLukeAndLeiaAliased{
  luke:human(id   :  2.1e-7) {
    name,
  }
  leia       ,  : human   ,,, ( , id ,, : ,, "10103") {
    name
  }
}

is a valid query and should be parsed without any errors. Is my assumption correct?

8.1.1 says Whitespace, other than within strings, is not significant. Your assumption should hold.

You're correct. Anything defined as a token grammar (consumes characters) is sensitive to whitespace (eg, string and number literals). Anything defined as a syntax grammar (consumes tokens) is not sensitive to whitespace or other ignored characters.

I'll try to clarify this in the spec
