How to render html buffer in emacs?

How to render html buffer in emacs?

[Hallvard B Furuseth]

How do I get Emacs to render a HTML buffer (as a web page, not as html
source)?  I've been looking a bit at the w3m doc, but it has hopeless
chapter names and only lists how to use it with some specific apps
(gnus, mail readers, etc).

The easiest way to do this is to use the browse-url package. 

,----[ C-h f browse-url-of-file RET ]
| browse-url-of-file is an interactive compiled Lisp function in `browse-url.el'.
| (browse-url-of-file &optional FILE)
| 
| Ask a WWW browser to display FILE.
| Display the current buffer's file if FILE is nil or if called
| interactively.  Turn the filename into a URL with function
| `browse-url-file-url'.  Pass the URL to a browser using the
| `browse-url' function then run `browse-url-of-file-hook'.
| 
| [back]
`----

,----[ C-h f browse-url-of-dired-file RET ]
| browse-url-of-dired-file is an interactive compiled Lisp function in `browse-url.el'.
| (browse-url-of-dired-file)
| 
| In Dired, ask a WWW browser to display the file named on this line.
| 
| [back]
`----

etc.

Or, browse-url-of-buffer

Sorry to butt in but: 
browse-url-of-file doesn't work here.. it gives this error
   browse-url: Wrong type argument: listp, w3m-browse-url

Which appears to mean my settings for w3m are interfering but not sure
what to do about it.  I'm not sure what all they are even but
I see:
  browse-url-browser-function is a variable defined in `browse-url.el'.
Its value is browse-url-firefox

So what do I need to do to have browse-url-of-file call firefox?

It looks like your configuration wants to use w3m and it is not loaded:

  (setq browse-url-browser-function 'w3m-browse-url)
  (autoload 'w3m-browse-url "w3m" "Ask emacs-w3m to show a URL." t)

Or if you want to use firefox instead:

  (setq browse-url-browser-function 'browse-url-firefox)

HTH,

Maybe I ought to mention that in nXhtml there is are several menu 
entries for viewing the file you are editing (for local file, for 
uploaded file etc).

This can actually be used to view also uploaded php/eruby/django etc 
files with your web browser.

You need to configure browse-url and tell it your preferred/default browser
is firefox. Best way to to this is through the customize mechanism. Do a

M-x customize-group <ret> browse-url

to get a list of what can be customized - its pretty straight-forward. 

Note that the error you get is telling you that emacs was expecting a list
and got instead a symbol/function name. Not sure where you have set that,
but you probably need to remove it and just use customize. One of the
advantages of customize is that it will often protect you from simple
errors like this by only allowing you to set things in the correct
format. Not sure where you have something ot of place without seeing a
backtrace, but check the variable browse-url-browser-function as a
start. Mine has 

,----[ C-h v browse-url-browser-function RET ]
| browse-url-browser-function is a variable defined in `browse-url.el'.
| Its value is w3m-browse-url
| 
| 
| Documentation:
| Function to display the current buffer in a WWW browser.
| This is used by the `browse-url-at-point', `browse-url-at-mouse', and
| `browse-url-of-file' commands.
| 
| If the value is not a function it should be a list of pairs
| (REGEXP . FUNCTION).  In this case the function called will be the one
| associated with the first REGEXP which matches the current URL.  The
| function is passed the URL and any other args of `browse-url'.  The last
| regexp should probably be "." to specify a default browser.
| 
| You can customize this variable.
| 
| [back]
`----

My relevant lines from the customize section in my .emacs are

 '(browse-url-browser-function (quote w3m-browse-url))
