Ruby 1.9 Hash syntax is still not parsed correctly

[janko]

Hash[*CodeRay.scan("{:foo => 'bar', foo: 'bar'}", :ruby).tokens]

 {"{"=>:operator,
 ":foo"=>:symbol,
 " "=>:space,
 "="=>:operator,
 ">"=>:operator,
 :begin_group=>:string,
 "'"=>:delimiter,
 "bar"=>:content,
 :end_group=>:string,
 ","=>:operator,
 "foo"=>:key,        # this should be parsed as `:symbol`
 ":"=>:operator,     # and this too
 "}"=>:operator}

It's intended behavior:

• The classic variant using => is using a literal Symbol, so it is highlighted as such.
• The "foo:" part is not really a Symbol (Symbols always begin with a colon), but a shorthand syntax for a Symbol key. I decided to highlight it as :key, so it is using the same colors as, for example, JSON.

I can see your reasoning, but consider this example: https://github.com/kyrylo/pry-theme/issues/30 (the project depends on CodeRay).

Particularly, the class key is considered as a keyword.

{
  foo: 1,
  class: 2
}

By the way, GitHub sees it as a symbol.

Not since 1.1, this was fixed in #126.

GitHub uses Pygments; it's an awesome highlighter written in Python, and the team is great, but it is not a Ruby reference ;-) VIM, for example, uses the same style as CodeRay; TextMate uses the GitHub style.
