Elisp: html6-mode

By Xah Lee. Date: . Last updated: .

This page shows a very simple example of writing a major mode for emacs.

Suppose you are designing HTML6, and it looks like this:

?xml 「version “1.0” encoding “utf-8”」〕
〔feed 「xmlns “http://www.w3.org/2005/Atom” xml:base “http://ergoemacs.org/emacs/”」

  〔title Xah's Emacs Blog〕

  〔link 「rel “self” href “http://ergoemacs.org/emacs/blog.xml”」〕
  〔link 「rel “alternate” href “http://ergoemacs.org/emacs/blog.html”」〕

You want to write a emacs major mode to syntax color it.

Here's the code.

;;; xah-html6-mode.el --- Major mode for editing html6. -*- coding: utf-8 -*-

;; http://xahlee.info/comp/html6.html

;;; HISTORY
;; version 0.3, 2016-09-08
;; version 0.1, 2010-12-17

(defvar xah-html6-font-lock-defaults nil "Value for font-lock-defaults.")

(setq xah-html6-font-lock-defaults
      '(("〔\\([^ ]+?\\) " . (1 font-lock-function-name-face))
        ("“\\([^ ]+?\\)”" . (1 font-lock-string-face))
        ("「\\([^」]+\\)」" . (1 font-lock-variable-name-face))
        ) )

(define-derived-mode xah-html6-mode fundamental-mode "HTML6"
  "sample simple mode for html6"
  (setq font-lock-defaults '(xah-html6-font-lock-defaults)))

(provide 'xah-html6)
