Question

我正在编写String类的扩展名：

#/lib/string.rb
Class String
   def linkme
     return self.gsub("[/link]", "</a>").gsub("[link=", "<a href='").gsub("]", "' target='_new'>")
   end
end

然而，当我在控制台中调用它时，我得到了这个：

>>require 'lib/string'
SyntaxError: ./lib/string.rb:5: syntax error, unexpected kEND, expecting $end
    from /usr/local/lib/site_ruby/1.8/rubygems/custom_require.rb:31:in `gem_original_require'
    from /usr/local/lib/site_ruby/1.8/rubygems/custom_require.rb:31:in `require'
    from /home/path/to/vendor/rails/activesupport/lib/active_support/dependencies.rb:153:in `require'
    from /home/path/to/vendor/rails/activesupport/lib/active_support/dependencies.rb:521:in `new_constants_in'
    from /home/path/to/vendor/rails/activesupport/lib/active_support/dependencies.rb:153:in `require'
    from (irb):11

我认为这应该在理论上有效，因为我没有......

这是我第一次尝试在Ruby中扩展这样的类，我觉得我做得很好，但也许S / O社区可以帮我把它包起来。

这对你有用

class String
  def linkme
    self.gsub("[/link]", "</a>").gsub("[link=", "<a href='").gsub("]", "' target='_new'>")
  end
end
