Creating a new buffer with text using EmacsClient

Question

I have a program that can send text to any other program for further analysis (eg sed, grep, etc). I would like it to send the data to Emacs and do analysis there. How would I

Answer 1

This does what you ask for:

emacsclient -e '(open-buffer-with "some\nstuff\nhere")'

(defun open-buffer-with (txt)
  "create a new buffer, insert txt"
  (pop-to-buffer (get-buffer-create (generate-new-buffer-name "something")))
  (insert txt))

Obviously you can customize open-buffer-with to do what you want.
