Question

I’m experimenting with Anemone, a ruby web spider framework. I want to know how do I print all methods associated with an object? For example, the code below outputs puts page.url but I want to know what other methods are available, other than url. How do I print out all associated methods?

require 'anemone'

    Anemone.crawl("http://www.fsu.edu") do |anemone|
      anemone.on_every_page do |page|
        puts page.url 
      end 
    end 

Answer puts (page.methods - Object.public_methods)

Answer 1

I’ve used this to sort out the uninteresting things:

irb> pp (page.methods - Object.new.methods).sort

Also, from the IRB I use the Wirble gem which has po and poc methods that do something similar:

irb> po page

Update: These days I use Pry. When Pry is available, the ls command works great:

pry> ls page
