Accessing Lisp Intro with eintr

Accessing Lisp Intro with eintr

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

Using info, this is the way to access the manuals using "elisp" and "emacs".

C-h i m elisp <Ret>
Visits the Emacs Lisp Manual.

C-h i m emacs <Ret> Visits the Emacs Manual.

But the above does not work quite well with the Introduction to Emacs Lisp manual, because
I cannot do

C-h i m eintr <Ret>

Rather, one has to do the following, with spaces etc.

C-h i m emacs Lisp Intro <Ret>

Would be grateful if info could access the intro with

C-h i m eintr <Ret>

I recommend using Hyperbole package to get some quicker functions:
{M-x package-install RET hyperbole} as then what you see here within
curly brackets becomes a link that you activate with M-RET:

- For Emacs Lisp reference I use always {C-h r TAB RET}

- To get into Emacs Lisp Intro is to evaluate this function:
  (info "(eintr) Top")

- To make a command, meaning invokable Emacs Lisp function:

(defun my-emacs-lisp-intro ()
  (interactive)
  (info "(eintr) Top"))

- To assign that command to a key:

(keymap-set global-map "C-c e" #'my-emacs-lisp-intro)

Now all what you need to do is press {C-c e} to get

"An Introduction to Programming in Emacs Lisp"

And remember that key bindings shall rather begin with C-c for
user configured functions.

You can put those definitions in your init file.

(defun my-emacs-lisp-intro ()
  (interactive)
  (info "(eintr) Top"))

Little problem is that function `keymap-set' is in my latest version of Emacs, so you better use:

(define-key global-map (kbd "C-c e") #'my-emacs-lisp-intro)

`m' matches your input against the title of the manual

`m int RET' does what you want.

Hi Heime,

In Info mode `c' runs `Info-copy-current-node-name',
whose docstring is:

  "Put the name of the current Info node into the kill ring.
  The name of the Info file is prepended to the node name in parentheses.
  With a zero prefix arg, put the name inside a function call to `info'."

Try to run this with your favorite variant of `C-x C-e':

  (info "(eintr) Top")

then navigate to another section, and type `M-0 c'. This will put a
sexp like (for example) this one in the kill ring:

  (info "(eintr) Kill Ring")

Then you can copy that sexp to your notes and use it as a hyperlink.
Do that for all the pages that you find relevant.
Good fortune will follow.

  Cheers,

P.S.: one can use this to access the eintr with just `M-x ei':

  (defun ei () (interactive) (info "(eintr) Top"))

but many people hate functions with very short names like that one.
