Float in Conditional Expression

[johnallen3d]

I'm just getting around to trying out the conditional operators (thanks!) and found a potential bug. If i use the JSON example from the README that includes float values for book prices I get an error. More specifically, if I see an error when I try to use floats in the JsonPath expression.

json = <<-HERE_DOC
{"store":
  {"bicycle":
    {"price":19.95, "color":"red"},
    "book":[
      {"price":8.95, "category":"reference", "title":"Sayings of the Century", "author":"Nigel Rees"},
      {"price":12.99, "category":"fiction", "title":"Sword of Honour", "author":"Evelyn Waugh"},
      {"price":8.99, "category":"fiction", "isbn":"0-553-21311-3", "title":"Moby Dick", "author":"Herman Melville","color":"blue"},
      {"price":22.99, "category":"fiction", "isbn":"0-395-19395-8", "title":"The Lord of the Rings", "author":"Tolkien"}
    ]
  }
}

This doesn't appear to have anything to do with conditional operators. If I take the simple example from the README...

> JsonPath.new('$..price[?(@ < 10)]').on(json)
=> [8.95, 8.99]

and try to use a float...

> JsonPath.new('$..price[?(@ < 10.0)]').on(json))
SyntaxError: (eval):1: `@' without identifiers is not allowed as an instance variable name
(eval):1: syntax error, unexpected end-of-input
(@ < 10['']['0'])

Huh, wth. I'm guessing it's because it picks up the . as an identifier. Thanks for reporting this @johnallen3d .

[Skarlso]

Yep. It picks the . up as an identifier. I'll fix it asap.

[Skarlso]

Done.

JsonPath.new("$..book[?(@['price']== 8.95 || @['price']== 22.99)]").on(json)
 => [{"price"=>8.95, "category"=>"reference", "title"=>"Sayings of the Century", "author"=>"Nigel Rees"}, {"price"=>22.99, "category"=>"fiction", "isbn"=>"0-395-19395-8", "title"=>"The Lord of the Rings", "author"=>"Tolkien"}]

@johnallen3d could you please have a go with the latest version mate?

[johnallen3d]

Woo hoo! Thanks!

    {
           "price" => 8.95,
