This doesn't answer your general question, but for getting Firefox to
reload the page you're editing, what about setting the browser tab to
reload every few seconds? There are a number of Firefox extensions that
do that (e.g. Tab Mix Plus).

Embedding external application in emacs (or using emacs to control exeternal application)

Is there a way to embed external application (such as
firefox) inside an Emacs buffer and use Emacs to control them? If not, would it be possible to simply send an external application (again like firefox) a command from within emacs without it being embedded. For example, say I was working on an HTML page in emacs and wanted to preview my changes by refreshing the page in firefox. I would just like to be able to say something like M-x refresh-firefox, and not have to click over to the firefox window to his refresh myself. What
would be required to add this feature?

 Is there a way to embed external application (such as firefox)
 inside an Emacs buffer and use Emacs to control them? If not,
 would it be possible to simply send an external application
 (again like firefox) a command from within emacs without it
 being embedded. For example, say I was working on an HTML page
 in emacs and wanted to preview my changes by refreshing the
 page in firefox. I would just like to be able to say something

Hi,

I don't think your first scenario is possible, but here I'm way out of my
depth. Just guessing because I don't know of any other "embedded" app.

Case two is possible.

You could look up "browse-url" in the emacs manual: Commands for interaction
with a browser.

But Emacs is able to start (a)synchronous subprocesses with or without a shell,
so calling another app with the current file-name as option should be
possible. All this is documented in the GNU Emacs Lisp Reference Manual. Search
for `start-process'.

Hope this helps

I should have read the manual myself: There is `browse-url-of-file' which
defaults to browsing the url of the current buffer's file.

Yes, but all these seem to load the file into another tab, not refresh
the current version.

What modifications to Emacs would be necessary to make it possible? (I'm guessing this would have to be done in C.)

Yes, but---I checked for Firefox and Epiphany---this is because the browsers
don't have a "refresh tab/window" command line option. Emacs can't do anything
about it.

It would be nice to now if one can trick a browser to refresh a page; Adobe
Acrobat can be tricked to refresh a file, too. Anyone?

But maybe it should be a feature request.

Uh oh, big ones, I guess ;-)

The (upcoming?) Emacs 23 supports the XEmbed specification. I'm quoting from the
"News file:

      "You can embed Emacs in another application on X11.  The new command line
      option --parent-id is used to pass the parent window id to Emacs.  See
      http://standards.freedesktop.org/xembed-spec/xembed-spec-latest.html for
      details about XEmbed."

But I don't think that this implies the other way round, the case that you want.

This is out of my league, maybe you should post this on the developer mailing
list.

There is a firefox package called mozlab that has an emacs
interface. This allows you to interact with firefox via a REPL where
you can perform various operations. may be of use for what you want.
