10. Some knick-knacks using emacs-w3m

Here are some handy tips to use emacs-w3m with other Emacs facilities.

• browse-url

  You can use emacs-w3m with the browse-url feature. For instance, put the following lines in your `~/.emacs' file:

  (setq browse-url-browser-function 'w3m-browse-url) (global-set-key "\C-xm" 'browse-url-at-point)

  Emacs-w3m will now be invoked when you type the C-x m key on a string which looks like a URL in any Emacs buffer. In addition, you can use emacs-w3m to preview an HTML file that you are just editing by typing the C-c C-v key (note that you need to use Emacs and the html-mode major mode to edit the HTML file).

  If you'd like to use another web browser than emacs-w3m when using the C-x m key when you are in an emacs-w3m buffer (who wants to do so?), add the following advice to `~/.emacs' file:

  (defadvice browse-url-at-point (around change-browse-url-browser-function activate) "Use Netscape only when it is invoked in an emacs-w3m buffer." (let ((browse-url-browser-function (if (eq major-mode 'w3m-mode) 'browse-url-netscape 'w3m-browse-url))) ad-do-it))

• dired

  You can use emacs-w3m to browse an HTML file in a dired buffer by typing the C-x m key. Use the following settings in your `~/.emacs' file:

  (eval-after-load "dired" '(define-key dired-mode-map "\C-xm" 'dired-w3m-find-file)) (defun dired-w3m-find-file () (interactive) (require 'w3m) (let ((file (dired-get-filename))) (if (y-or-n-p (format "Use emacs-w3m to browse %s? " (file-name-nondirectory file))) (w3m-find-file file))))

• hnf-mode

  You can see the newest diary using emacs-w3m and the hyper nikki system. Put the following lines in your `~/.emacs' file and type the C-c C-b key in an hnf-mode buffer:

  (defun w3m-hnf-browse-url-w3m (url &optional new-window) (interactive (browse-url-interactive-arg "URL: ")) (save-selected-window (pop-to-buffer (get-buffer-create "*w3m*")) (w3m-browse-url url new-window))) (setq hnf-browse-url-browser-function #'w3m-hnf-browse-url-w3m)

• Gnus

  You've mistaken the entrance if you are a Gnus user and this section is the first page you read in this Info. See 6. Hooking emacs-w3m into mail/newsreaders first.

  By default, Gnus will not apply the treatment variables, for instance gnus-treat-strip-banner, to `text/html' parts. To have them applied to `text/html' parts automatically, there are two ways to do that:

  ;; Apply all the treatments to text/html parts. (eval-after-load "gnus-art" '(add-to-list 'gnus-article-treat-types "text/html"))

  ;; Apply a certain treatment to text/html parts. (setq gnus-treat-strip-banner '(or t (typep "text/html")))

  Also See section `Customizing Articles' in The Gnus Manual, for details.

  In addition, the experimental code below is used to display `multipart/related' pictures. The place might be something wrong.

  (eval-after-load "gnus-art" '(or (assoc "multipart/related" gnus-mime-multipart-functions) (setq gnus-mime-multipart-functions (cons (cons "multipart/related" (byte-compile (lambda (handle) (gnus-mime-display-mixed (cdr handle))))) gnus-mime-multipart-functions))))

• yahtml-mode

  You can use emacs-w3m to preview an HTML file that just you are editing with the yahtml-mode. Here is an example:

  (defadvice yahtml-browse-html (around w3m-yahtml-browse-html activate compile) (w3m-goto-url (ad-get-arg 0) t))

• jisx0213

  You can use JIS X 0213 character set in Emacs using the jis0213 module which is bundled in the Mule-UCS package. Although the decode-char function in Emacs 21 and later is overridden by mucs (jis0213 loads mucs) and it stops working properly for the ucs coded character set, it has been reported that also to load the unicode module seems to solve the problem. The reason has not been made clear yet. Here is an example for the `~/.emacs' file:

  (require 'unicode) (require 'un-define) (require 'jisx0213)
