Making Menu Bar with an About Buffer

Making Menu Bar with an About Buffer

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

Have seen that Emacs has "About Emacs" and "About Gnu". I would like to do the same with a new "Menu Bar"
called "Gundit" where there is "About Gundit" which prints about Gundit in a dedicated buffer.

How can this be done?

You define function and add it to menu.

My function below uses about: hyperlinks, it decides what to display.

I have defined "about:" hyperlink in `browse-url-handlers' to be:

   '(("gemini:" . elpher-go)
     ("gopher:" . elpher-handler-go)
     ("about:" . hyperscope-about)
     ("hyperscope:" . hyperscope-go)
     ("e2dk://" . amule-handler)))


Then this function is showing About, it has Hyperlinks underline where
it says about:

(defun hyperscope-about (&rest what)
  (interactive)
  (let* ((what (if (eql 'cons (type-of what))
		   (car what)
		 what))
	 (what (if (null what) "about:hyperscope" what)))
    (cond ((string= what "about:hyperscope") (hyperscope-text-view "
	 ===================================================
	 Hyperscope - Dynamic Knowledge Repository for Emacs
	 ===================================================
                           about:emacs
                           about:emacs-fancy
                           about:hyperscope
"))
	  ((string= what "about:emacs") (about-emacs))
	  ((string= what "about:emacs-fancy") (fancy-about-screen))
	  (t (hyperscope-text-view "Maybe you wish to read about:hyperscope")))))

What, it looks like that in the source?

That could be automated with variables and not hardcoded ...

Don't you think its better to use electrons ONCE when this string is de-
signed rather than EVERYTIME when someone is looking at it?

Nope, because that also means instead of doing it once and
forever getting it right everytime someone does it we will
have the same (poor) situation ...

And, if you are concerned for the electrons, a program can
store the result in a variable once just as well as any human
can storing it in hard-coded code (actually better, because
then checks can be made the input makes sense).
