Subject: [ruby-core:40799] [ruby-trunk - Feature #5578] Embedded YAML for Ruby 2.0


Issue #5578 has been updated by Thomas Sawyer.


YAML defines `...` as end of document marker.

  data = ---
         a: 1
         b: 2
         c: 3
         ...  <= this

Yes, it is something like HERE docs, but more concise. I also have this gut feeling that it could evolve into in even more useful ways in the future, though I can't quite put my finger on it yet. Some interesting "hints" though include:

  data = eval(source)

Where source could be Ruby or YAML.

  load 'foo.yml'

You'd have to use a callback of some sort to get the data, but it's interesting nonetheless that it would work.

And I wonder if a "Ruby code escape" could be worked-in, e.g.

  class A; end
  foo = "foo"

  data = ---
         a: ->{ A }
         b: ->{ ->{ foo } }
         c: ->{ 1 + 1 }
         ...

  data #=> {'a'=>A, 'b'=>#<Proc ...>, 'c'=>2}

You get the idea.

Way cool would be support for embedded YAML.

  data = ---
         a: 1
         b: 2
         c: 3
         ...
