[erlang-questions] get erlang-shell working, displayed & active right after emacs startup - SOLVED

[ami]

Hi Steve,

I’m quite a newbie in emacs lisp & emacs internals, So your code seemed 
to me some kind of magic. I googled a lot, read a lot. 

Your code “as is” didn’t work. But it really helped me.

Eventually, I came to this:

(erlang-shell)

(add-hook 'emacs-startup-hook
        '(lambda () (
                    (display-buffer "*erlang*")
                     )))

And it really works! 
(under OSX 10.9.3, Emacs 24.3(9.0)(downloaded from http://emacsformacosx.com/) - 
actually, “option key WORKS in this build as M)



I tried to place (erlang-shell) directly into the hook’s lambda, like

(add-hook 'emacs-startup-hook
        '(lambda () (
                    (erlang-shell)
                    (display-buffer "*erlang*")
                     )))

But that didn’t work.
Somewhy I was constantly getting an "Invalid function: (erlang-shell)”
message. How can a variable be visible in outer scope but be invisible in
inner scope… Magic :) But I’m a noob in emacs lisp though.
