Ruby有像JavaDoc这样的东西吗？

Question

I am trying to learn Ruby, but I am having problems using the API. For example, I am looking at this:

decode(json) Converts a JSON string into a Ruby object.

# File lib/active_support/json/decoding.rb, line 11
11:       def decode(json)
12:         YAML.load(convert_json_to_yaml(json))
13:       rescue ArgumentError => e
14:         raise ParseError, "Invalid JSON string"
15:       end

How can I find out about how to use the returned "Ruby Object"? Like the methods available and etc? Thanks a ton.

Answer 1

try this:

http://ruby-doc.org/

and this

http://rubyonrails.org/documentation

Answer 2

Yes it has:

http://ruby-doc.org/

Look for example:

http://ruby-doc.org/core-1.9.3/

There you could search api by name of method or name of the class.
