Welche Programmiersprache ist das?
Hallo,
in welche Programmiersprache wurde Emacs geschrieben? Ich dachte früher C oder C++, aber wie ich nach kurzer Betrachtung einer Quelldatei festgestellt habe, handelt es sich hier nicht um C/C++.

;;; Commentary:
;; Provides tool-bar-mode' to control display of the tool -bar and ;; bindings for the global tool bar with convenience functions ;; tool-bar-add-item' and `tool-bar-add-item-from-menu'.
;; The normal global binding for [tool-bar] (below) uses the value of
;; tool-bar-map' as the actual keymap to define the tool bar. Modes ;; may either bind items under the [tool-bar] prefix key of the local ;; map to add to the global bar or may set tool-bar-map'
;; buffer-locally to override it. (Some items are removed from the
;; global bar in modes which have special' as their mode-class'
;; properlty.)
;; Todo: Somehow make tool bars easily customizable by the naive?
;;; Code:
;;;###autoload (define-minor-mode tool-bar-mode "Toggle use of the tool bar. With numeric ARG, display the tool bar if and only if ARG is positive.
See tool-bar-add-item' and tool-bar-add-item-from-menu' for
conveniently adding tool bar items."

Hi,
"Fnord is why lisp has so many parentheses" ;)
http://www.fnord.org/occult/discordia/text/what.is.fnordIch glaube der Text ist nur was für Insider. Was _genau_ ist fnord?

Was Fnord ist? Fnord ist Fnord! ;)
Genau das ist der "Knackpunkt" - es ist unmöglich, diese Frage zu stellen und noch unmöglicher, eine präzise Antwort zu geben, denn es gibt keine ansolute - die dutzenden Definitionen geben dennoch hilfreiche Anhaltspunke. Es ist nicht möglich, Fnord mit einem menschlichen Geist zu begreifen, es übersteigt schlichtweg jede Vorstellungskraft... ;) Fnord ist die Farbe, die nur Blinde sehen...Don't see the fnords and they won't eat you... ;)

Ach! Jetzt verstehe ich es! Den Text habe ich mir gleich zu den Lesezeichen hinzugefügt.
