[pinkanon pinkanon]

The echo area is also used to display the minibuffer

 Eval this:
  
 (progn (minibuffer-message "hello world") (print (format "current message: %s" (current-message))))
  
 to get "current message: nil" in the *Messages*. If message is used in place of minibuffer message, works
 as expected.

I think your expectations are incorrect, and Emacs works correctly in
this case.
 

 The reason I think current-message should work with minibuffer-message is due to its docstring: "Return the
 string currently displayed in the echo area, or nil if none."

The echo area and the minibuffer are two different buffers. They both
use the same mini-window to display their text, but they are not the
same.

 

Sorry, should've included this, I am basing my assumption on the manual

https://www.gnu.org/software/emacs/manual/html_node/emacs/Echo-Area.html

"The echo area is used to display the minibuffer".

 

Hmm. I guess I just want the contents of the mini window then, whether it was produced by message or minibuffer-message. And the realization that it's a window yields the following code, but it's not working...

 

(progn

  (minibuffer-message "hello world")

  (with-selected-window (minibuffer-window)

    (print (format "ms: %s" (buffer-substring-no-properties (point-min) (point-max))))))
