Have you seen the api doc page? http://www.ruby-doc.org/core/Kernel.html#method-i-p

Each method you can call "directly", e.g: print, p, abort, puts, readline, etc., is located in the Kernel class.

(Kernel.methods - Object.methods).sort.each do |method|
   puts method
end

Answer 3

You can find more information about the p method from the Ruby documentation of the Kernel module:
http://www.ruby-doc.org/core/Kernel.html#method-i-p

p(obj) → obj

p(obj1, obj2, ...) → [obj, ...]

p() → nil

For each object, directly writes obj.inspect followed by a newline to the program’s standard output.

S = Struct.new(:name, :state)
s = S['dave', 'TX']
p s

produces:

#<S name="dave", state="TX">
