creating a sub-menu

creating a sub-menu

[ken]

Trying to create a sub-menu under "Edit".  Got part of the way there, 
but still missing something.

(define-key menu-bar-edit-menu [insert-xascii-chars]
   '(menu-item "Insert non-ASCII characters" xascii

    (xascii  "\C-xaa"   "ä"        "ä` (ä)"          ("ä"))
    (xascii  "\C-xaA"   "Ä"        "Ä` (Ä)"          ("Ä"))
    (xascii  "\C-xao"   "ö"        "ö` (ö)"          ("ö"))
    (xascii  "\C-xaO"   "Ö"        "Ö` (Ö)"          ("Ö"))
    (xascii  "\C-xau"   "ü"        "ü` (ü)"          ("ü"))
    (xascii  "\C-xaU"   "Ü"        "Ü` (Ü)"          ("Ü"))
    (xascii  "\C-xas"   "ß"        "ß` (ß)"          ("ß"))
    (xascii  "\C-xa<"   "«"        "«` («)"          ("«"))
    (xascii  "\C-xa>"   "»"        "»` (»)"          ("»"))))

Above yields error:
Debugger entered--Lisp error: (wrong-type-argument arrayp xascii)

When I evaluate it in a recent Emacs build from the bzr trunk, I get no
error.  But instead of adding a submenu to the Edit menu, it just adds
the entry "Insert non-ASCII characters" (when I click on that entry, it
tries to execute the xascii command, and since I have that, I get "Lisp
error: (void-function xascii)").  If you want a submenu, then instead of
a command name, the third item in your menu-item list should be a
(variable whose value is a) keymap defining the menu items of the
submenu, e.g., something like the following:

(defun kg-insert-ä ()
  (interactive)
  (insert "ä"))

(defun kg-insert-Ä ()
  (interactive)
  (insert "Ä"))

(defvar xascii-menu
  (let ((menu (make-sparse-keymap "Insert non-ASCII characters")))
    (define-key menu [kg-insert-Ä]
      '(menu-item "Insert `Ä'" kg-insert-Ä :keys "C-x a A"))
    (define-key menu [kg-insert-ä]
      '(menu-item "Insert `ä'" kg-insert-ä :keys "C-x a a"))
    menu))

(define-key menu-bar-edit-menu [xascii-menu]
  `(menu-item "Insert non-ASCII characters" ,xascii-menu))

Thanks, Steve,

I tried this code and it is definitely progress over mine in that it 
displays menu items under the "Insert non-ASCII characters" heading. 
However, those non-ASCII characters (e.g., `Ä' and `ä') don't display in 
the menu under that heading properly; probably owing to the menu 
subsystem of the emacs frame not handling utf-8... or 8-bit characters 
of any kind.  Secondly, the key combos (e.g., C-xaA and C-xaa) remain 
undefined.

But you've advanced the code over what I had and I appreciate that very 
much.  The bit of explanation you provide is also helpful.  Together 
with the bits in the Elisp Manual and other sources on the web, the 
total picture on adding a sub-menu into an existing menu heading is 
starting to come together, though still I'm far from being able to 
articulate it the way I want and would need in order to be helpful to 
anyone else.  So I'll work on it more in whatever spare moments I have. 
  I'm sure I'll get it eventually.

Thanks again,
ken

They display fine in the menu in my Emacs.  If you're using a
Unicode-capable Emacs (23 or later), they should display for you too,
unless some setting in your system, or maybe some X setting, is
preventing it.

The use of :keys in a menu item is only for displaying in the menu the
string corresponding to a key binding that you have defined elsewhere,
either using global-set-key, local-set-key, or, if you only want them to
be used in a specific key map, using define-key.

Good to know.  I'll have to remember that when I eventually get around 
to upgrading.  Until then I can use the '\xxx' (decimal) representations 
of them.

Alright!  Didn't know that was needed, but cool, done already a lot... 
that's cake.

dunno about the error, but if all you want is to easily type German, why
don't you use an input method? `M-x set-input-method latin9-prefix RET'
and you can type "a to get ä, ~s to get ß, ~< to get «, etc.

(info "(emacs) Input Methods") for details.

Thanks for your response, Joost.  But I already have an easier way than 
that to change the input method, one which takes just two mouse 
clicks... and then another two mouse clicks to return to my normal input 
method.  But I want a way so that all I need do is "C-xaa" to get 'ä'-- 
so I can type this and other characters without breaking the flow of my 
typing.  I want these listed in the menu also because I might not 
remember all the key combos for all the characters.  (I'll likely add 
more in future.)

That's too much. It's also the wrong input medium. ;-) Toggling the
input method can be done with `C-\', which IMHO is much much easier and
quicker than using the mouse.

Using C-\ will allow you to do just that. (In fact, I don't see any
reason why one would want to disable the input method. When I type
German or Dutch, I just toggle the input method and keep it until I kill
the relevant buffer.)

Well, I can't really help with the menu (I'm not even sure what this
xascii is...) but I do know that this error:

>>> Debugger entered--Lisp error: (wrong-type-argument arrayp xascii)

tells you that Emacs is expecting an array but getting xascii. In this
case the array Emacs is expecting must probably be either a string or a
vector, since a boolean vector or a char table doesn't seem to make
sense in a menu.

Don't know if that helps, though...
