Where am I going wrong in defining emacs major mode?
1
I am trying to define a new mode which inherits everything from Org mode, called web mode.
Here is a preliminary amateur stab at this.
(defvar web-mode-syntax-table
org-mode-syntax-table
"Syntax table used while in `web-mode'.")
;; Create the keymap for this mode.
(defvar web-mode-map
org-mode-map
"Keymap for `web-mode'.")
(setq web-highlights
'(("Sin\|Cos\|Sum" . font-lock-function-name-face)
("Pi\|Infinity" . font-lock-warning-face)))
;; set files ending in .web to open in web mode.
(add-to-list 'auto-mode-alist '("\.web\'" . web-mode))
(define-derived-mode web-mode org-mode "web-mode"
"Major mode based on Org-mode"
(kill-all-local-variables)
(setq major-mode 'web-mode)
(setq mode-name "Web Mode")
;; Tell font-lock mode about some things which
;; need to be highlighted.
(setq font-lock-defaults '(web-highlights))
)
However, when web-mode is loaded in a text file it seems identical to the plain-vanilla text mode. The key-words Sin, Cos and Sum get highlighted in blue correctly and the Pi and Infinity in bold red font, but otherwise nothing seems to have been inherited from Org mode, and seems indistinguishable from text mode.
Why is this?

I don't have the answer, but I have various comments:the"web-mode"arg is the mode-name, so remove the(setq mode-name "Web Mode"). Similarly, remove the setq ofmajor-modeand the call tokill-all-local-variablessince they're already performed bydefine-derived-modefor you. Along the same lines: defineweb-mode-mapas(make-sparse-keymap)andweb-mode-syntax-tableas(make-syntax-table):define-derived-modewill make sure they inherit from the corresponding org-mode table. One more thing: your setting offont-lock-defaultsoverrides org-mode's font-lock setup.
