I am trying to duplicate the following bash command in Elisp:
curl https://google.com | readability https://google.com
Here's what I have so far, but it doesn't capture the piping "| readability" part of it. How can I use Elisp to pass info that will be interpreted as "from stdin"?
(shell-command-to-string (format "readability %s \n%s" url htmls))
