I have, what I thought, was a pretty simple problem that someone would have created a gem for, but I am having a hard time searching for the silver bullet.

1) I'd like take a URL 2) create an md5, or "snapshot" of the site contents 3) then at a later date, see if the site has changed.

Is downloading the site and diffing the files the best way to do that? is there a way to serialize or encapsulate the site in a data object some how?

  • You mean like `wget -m`? That plus `git` could go a long way towards what you want here, and it'll do all sorts of fun stuff like show diffs for free. – tadman May 25 '16 at 19:53
