About Package using a menu

About Package using a menu

[Heime via Users list for the GNU Emacs text editor]

Been going through the settings for menus, sub-menus and menu-items.

Would like to make a menu called Xepty with an "About Xepty". The result would be as
happens with (Help > About Emacs) and (Help > About Gnu). A dedicated buffer shows up
with xepty-about being shown.

(defvar xepty-about "Xepty is Free Software.")
(define-key-after global-map

[menu-bar xepty]

(cons "Xepty" (make-sparse-keymap "Xepty"))

'tools)

That's OK. Real programmers don't use them, but they are okay
to program ...

Yes, but a genius does what is needed.

Is easy-menu-define the only way to make submenus?

No, of course not.  The Elisp manual has a chapter
that tells you all about defining menus: in node
"Defining Menus":

https://www.gnu.org/software/emacs/manual/html_node/elisp/Defining-Menus.html

Easy menu isn't even _mentioned_ in that chapter.

Have been playing with constructing a "Xepty menu" with a "Daphne submenu",  
but how do I make it to display?

;; Make a Daphne submenu

(defvar daphne-menu (make-sparse-keymap "Xepty"))

(define-key daphne-menu [tags-repl-continue]
  '(menu-item "Continue Replace" multifile-continue
              :help "Continue last tags replace operation"))

(define-key daphne-menu [tags-repl]
  '(menu-item "Replace in tagged files" tags-query-replace
              :help "Interactively replace a regexp in all tagged files"))

(define-key daphne-menu [separator-replace-tags]
  '(menu-item "--"))

(define-key daphne-menu [Xepty]
  (list 'menu-item "Xepty" daphne-menu))

;; Make a Xepty menu

(define-key global-map [xepty-menu words]
  (cons "Xepty" (make-sparse-keymap "Xepty")))

;; Define specific subcommands in this menu.
(define-key global-map [xepty-menu words forward]
  '("Forward word" . forward-word))

(define-key global-map [xepty-menu words backward]
  '("Backward word" . backward-word))

(define-key global-map [C-S-down-mouse-1]
   xepty-menu)

Keep reading.

Node Menu Keymaps has everything you need.
Node Menu Example shows you an example.
Etc.

My problem is about understanding how to make a new parent menu.  The example assumes 
that the parent menu (menu-bar-edit-menu) already exists.

This is how make parent "xepty-menu, then add "daphne-menu" as submenu.

(define-key global-map [xepty-menu words]
  (cons "Xepty" (make-sparse-keymap "Xepty")))

(define-key xepty-menu [Daphne]
  (list 'menu-item "Daphne" daphne-menu))

Have managed to display a parent menu.  Would you holp a bit on how to insert a submenu?

Here is the making of a parent menu "xepty-menu".

(defvar xepty-menu (make-sparse-keymap "xepty"))

(define-key-after global-map [menu-bar xepty-menu]
  (cons "Xepty" (make-sparse-keymap "xepty"))
  'tools )

--------------------

Here I want to make submenu "daphne-menu"

(define-key daphne-menu [xepty-menu]
  '(menu-item "Continue Replace" multifile-continue
              :help "Continue last tags replace operation"))
(define-key daphne-menu [xepty-menu]
  '(menu-item "Replace in tagged files" tags-query-replace
              :help "Interactively replace a regexp in all tagged files"))
(define-key daphne-menu [xepty-menu]
  '(menu-item "--"))

----------------------------

How can I add submenu daphne-menu in the following?

(define-key global-map [menu-bar xepty-menu daphne]
  '("Next Line" . next-line))

1. You can pop up a menu; it need not have a parent.

   Pretty much anywhere you can use a keymap you can use
   a menu.

   As the (entire) text of node Menu Keymaps tells you:

    "A keymap can operate as a menu as well as defining
     bindings for keyboard keys and mouse buttons.  Menus
     are usually actuated with the mouse, but they can
     function with the keyboard also.  If a menu keymap
     is active for the next input event, that activates
     the keyboard menu feature."

2. You can use an existing menu as parent, or create one.

Nope; sorry, too busy.  Hopefully someone else will
pitch in.  Or maybe you'll find the answer yourself
first, as you did for your other questions (e.g.,
how to display a parent menu).

Life's not easy.  Can't even trust programmers.

Dear Heime,

Here is a submenu that works as you wish.

(defvar xepty-menu (make-sparse-keymap "xepty"))
(defvar daphne-menu (make-sparse-keymap "daphne"))

;; Here is the xepty parent menu

(define-key-after global-map [menu-bar xepty-menu]
  (cons "Xepty" (make-sparse-keymap "xepty")) 'tools)

;; Here you get the daphne submenu

(define-key-after global-map [menu-bar xepty-menu daphne-menu]
  (cons "Daphne" (make-sparse-keymap "daphne")) 'kill-buffer)

;; Here you append function commands in daphne submenu

(define-key global-map [menu-bar xepty-menu daphne-menu bash]
	    '("Bash" . sh-mode))

;; Here you append another function command in daphne submenu

(define-key global-map [menu-bar xepty-menu daphne-menu elisp]
	    '("Emacs Lisp" . emacs-lisp-mode))

Re: [External] : Re: About Package using a menu

[Jean Louis]

I just do this:

(easy-menu-define cf-people-menu  global-map "People menu"
  (list "People"
	cf-people-menu-find-people
	cf-people-menu-list-of-people
	cf-people-menu-collaborate
	cf-people-menu-add-new-people
	cf-people-menu-edit-people
	cf-mailing-list-menu
	cf-central-files-menu
	rcd-db-database-maintenance-menu
	))

Then for each of those entries I have:

(defvar cf-people-menu-find-people
  (list "Find people"
	["Find people" cf-people t]
	["Find people by name" cf-people-by-name t]
	["Find people by query" cf-people-search-ts-query t]
	["Find files of person" cf-find-files-of-person t]
	["Find people by description" cf-people-by-description t]))

`easy-menu-define', are you sure that's a good idea, why don't
you stick to Elisp?

Doing things similarly to your code (calling the defvar using its name), but still get an error.
I am also using submenus.  Can one perhaps do ["Find People" cf-people-menu-find-people t] ?

1) Write a version that works

2) Expand, if it still works, expand more ...

3) When it doesn't work, post the code here
