;; OLD DOCS:
;; Thanks for erbot's/erbot's behavior and their data go to a lot
;; of people on #emacs, like:
;; kensanata (Alex Schroeder)
;; resolve (Damien Elmes)
;; bpt  (Brian P. Templeton)
;; forcer (Jorgen "forcer" Schaefer)
;; and many others

;; and also to bot(s):
;; apt on debian, for english syntax examples.

;; Thanks for code go to:
;; David Edmonsdon (who wrote erc-robot.el which is what this started
;; out from).
;; Nick Hober (who wrote google.el)






;;; David E's Commentary:

;; erbot is a derivative of David's erc-robot.el --- that code was
;; copied over on 2002-09-02 into erbot.el.  Erbot seeks to make the
;; bot similar to apt on #debian.. viz: English style.. yet allowing
;; access to commands via the "cmd" command.  Erbot shall seek to
;; save all its information periodically, and publicly...


;; Erc-robot implements a simple robot for ERC.

;; Installation:

;; The robot uses hooks to gain access to ERC.  The following need to
;; be executed after ERC has loaded:

;;     (load-library "erbot")


;; It is particularly important that the remote robot function is added
;; to the tail of the PRIVMSG hook.

;; Robot commands are declared using the list "erbot-commands".
;; XXX better description of the functions.
;; An example might be:

;; (setq erbot-commands
;;       '(
;; 	("cmds" t (lambda (args)
;; 		  (concat "commands available: "
;; 			  (mapconcat
;; 			   (lambda (e)
;; 			     (car e))
;; 			   erbot-commands " "))))
;; 	("hello" t (lambda (args) "hello to you too !"))
;; 	("zippy" t (lambda (args) (erc-replace-regexp-in-string "\n" " " (yow))))
;; 	("music" t (lambda (args) (concat "now playing: "
;; 					(let ((track (dme:now-playing)))
;; 					  (if track
;; 					      track
;; 					    "nothing.")))))
;; 	("echo" t (lambda (args) args))
;;	; only i'm allowed to talk to my doctor !
;; 	("doctor" nil erc-doctor)
;; 	("version" t (lambda (args) (erc-version)))
;;       ))

(defvar erbot-paranoid-p t
  " Meant as a CATCHALL for security. Setting this variable to non-nil
should disable most features. When non-nil, all potentially funny
functions are disabled.  We think these functions are safe, but we
disable them in any case.  We also disable all functions that we can
that may potentially freeze the bot or severly slow it down upon
receiving weird requests.


t by default.  No enablings like erbot-setf-p, etc. will work
unless this is non-nil. If this is non-nil, erbot is paranoid, it will
not allow apply, setf, funcall, sregex, etc. even if the corresponding
variables are turned on.

NOTE: Making this variable nil and later non-nil in the middle of a
running emacs session will NOT make your bot completely paranoid.  You
need to have this function non-nil BEFORE you load erbot. See, for
example, how we define fs-kbd.
