emacs-elisp-programming's Issues

Good work

Good work :)
But, no updates?

I tried to convert Elisp_Programming.org to pdf,
But could not succeed :(

(position) not defined

Does (position) need to be defined by some library?

ELISP> (position 2 '(5 6 7 8))
*** Eval error ***  Symbol's function definition is void: position

I'm using emacs version 24.4.90.1

Alist example not quite right

Hi,

Yr function plist->alist creates a list of lists rather than a list of cons cells. Should be something like:

(defun plist->alist (plist)
  (if (null plist)
      '()
      (cons
       (cons (car plist) (cadr plist))
      (plist->alist (cddr plist)))))

How to edit and return string in Emacs Lisp?

(defun buffer-out ()
  (interactive)
  (let ((buffer (current-buffer))
	(value (buffer-string)))
    (kill-buffer buffer)))

(defun buffer-string-out ()
  (interactive)
  (buffer-string))

(defun edit-string (string)
  (interactive)
  (let ((buffer "*edit-string*"))
    (get-buffer-create buffer)
    (switch-to-buffer buffer)
    (set-buffer buffer)
    (let ((inhibit-read-only nil))
      (insert string)
      (fundamental-mode)
      (local-set-key (kbd "C-c C-c") 'buffer-out))))

;;      (add-hook 'kill-buffer-hook 'buffer-string-out))))

(setq ok (edit-string "OK"))

I am trying to get this work, could you point me to a solution to edit string, and return the string back?

get-value doesn't appear to be defined

In the assoc list segment get-value is called, but it's not a built-in that I can find?

Example of "1.6.6 Functions with Property List argument" need to be corrected

(defun make-shell-interface (&rest params)
 
 ;;<snip>
  (let
       ((name   (plist-get params :name ))
        (type   (plist-get params :type))
        (path   (plist-get params :path))
        (buffer (plist-get params :buffer)))
    (list
     (cons 'name buffer) ;; <== should be (cons 'name name)
     (cons 'type type)
     (cons 'path path)
     (cons 'buffer buffer))))

Change the following line from

(cons 'name buffer)

to

(cons 'name name)

Will it be updated?
