Symbol's function definition is void: latex-indent-line [Mac OS X]

Symbol's function definition is void: latex-indent-line [Mac OS X]

[Angelo Graziosi]

Just for the sake of completeness I want to flag this issue with 
Emacs-app...

When 24.1 was released, I installed Emacs-app by means of MacPorts tools 
on a MBP with Lion 10.7.4.

My init (reduced to a simple test case) file is:

$ cat .emacs.d/init.el

(global-set-key [13] 'newline-and-indent)

(defun latex-return( ) (interactive) (latex-indent-line) 
(newline-and-indent))


(add-hook 'latex-mode-hook
 	  '(lambda()
 	     (local-set-key [13] 'latex-return)
 	     ;(auto-fill-mode 1)
 	     (turn-on-reftex)

 	     ;; Add index to menu bar
 	     (imenu-add-to-menubar "Contents")
 	     )
 	  )


and all worked fine with .tex file...

I have worked since this morning with a .tex file (inserting lines with 
ENTER and then text, deleting lines etc.) without problems until a few 
minutes ago: suddently pressing ENTER does not work any more (Emacs beeps) 
and in the minibuffer I got the message:

   latex-return: Symbol's function definition is void: latex-indent-line


and I can't edit .tex file any more...

This is strange because it worked and works with Aquamacs and Emacs on 
other systems (GNU/Linux, Cygwin, Windows). They are many years I have 
that "defun" in my init files...

I have not done any update since yesterday, so I would exclude an update 
issue. Perhaps a caching issue? How on MBP?

TIA,
  Angelo.

There was never a function latex-indent-line in Emacs (tex-mode defines
latex-indent).  It must have been defined by some add-on package.

You may try to reproduce with:

cp init.el-test ~/.emacs.d/init.el
emacs24[|| trunk] test_subfig.tex

go to the end of a line, "\section{Introduction}" for example.

Press ENTER to insert a blank line: it does not work for me, it prints

   Symbol's function definition is void: latex-indent-line

in the minibuffer..

I have tested it with Emacs-app 24.1 on Mac OS X (via MacPorts); with rev. 
109400 on Cygwin, and a week old trunk on GNU/Linux Fedora 16.

Ciao,
Angelo.

(defun latex-return( ) (interactive) (latex-indent-line) (newline-and-indent))

In your init.el you have:

(defun latex-return( ) (interactive) (latex-indent-line) (newline-and-indent))

and as stated below, latex-indent-line does not exist, but latex-indent do.
So no wonder you get Symbol's function definition is void: latex-indent-line.
What did you expect?
