Alternative oembed solutions

oembed_translator.rb

class OembedTranslator
  include ActionView::Helpers::TagHelper
  
  # usual stuff over here..

  def embed
    @content.gsub(/(?:<a.+?<\/a>)|((?:www|https?).*?)(?=\s|\Z)/) do |match|
      match.present? or next # regexp not perfect yet, there are nil matches for some reason
      oembed_code_for(match)
    end
  end

  private

  def oembed_code_for(link)
    response = OEmbed::Providers.get(link, :width => 450, :maxWidth => 450)
    response.html
  rescue OEmbed::NotFound
    link.start_with?("<a") ? link : content_tag(:a, link, href: link)
  rescue OEmbed::Error
    link
  end
end

Basic idea is: capture all those anchors first, with lower prio then the remaining urls. For each of them there is a answer with what to replace, delivered by the oembed_code_for method.

Bonus cake for me! harhar It's: /((?:<a.+?</a>)|(?:www|https?).*?(?=\s|\Z))/

nice one
