How do I convert Protocol Relative URLs to standard HTTP?

I'm working with the wkhtmltoimage utility which does not support protocol relative URLs such as this: <script src="//cdnjs.cloudflare.com/ajax/libs/numeral.js/1.4.5/numeral.min.js"></script>

I need to convert it to: <script src="http://cdnjs.cloudflare.com/ajax/libs/numeral.js/1.4.5/numeral.min.js"></script> in Ruby. I'm wondering what the most efficient way of finding these type of URLs as I can't figure out how to write a regex for them and then prepend http: to it.

Thanks in advance.

Solution

  • You can use perl for that :

    perl -pi -e 's/src="\/\//src="http:\/\//' *

    This statement above will replace all patterns found in a directory.
