Question

This is something I wasn’t expecting.

I’m using anemone to count links in pages (anemone is a web spider framework for ruby)

Its pretty straightforward, but why won’t this work?

anemone.on_every_page do |page|
    @myLinks =[]
      page.links.each_with_index do |link,index|
        puts "HOWDY PARDNER"
        @tempLink =(link.to_s + ",")
        @myLinks[index] = @tempLink
      end
end

The part in question is the addition of link.to_s +”,”

The reason I’m doing this addition is that links.to_s comes down as an entire string with no spaces. I’d like to sepsrate them with a , so I can use .split() later.

Answer 1

to split (you mean join?) them later you don’t need to add “,”:

@my_links = ["Link 1", "Link 2", "Link 3"]
@my_links.join(", ")
#=> "Link 1, Link 2, Link 3"
@my_links.to_sentence
#=> "Link 1, Link 2, and Link 3"

That’s all you need, I think.

anemone.on_every_page do |page|
  @my_links = page.links.join(", ")
end
