Isn't that Common Lisp?

(require "asdf")

(defun slurp-stream-io-command (command string)
  "Returns the output of a command to which string has been fed, very
usable for markdown, emacs Org mode processing and similar"
  (with-input-from-string (in string)
    (uiop:run-program command :input in :output :string :ignore-error-status

(slurp-stream-io-command "markdown" "## hello")

"<h2>hello</h2>
