I created my own function though... actually two of them: one to open the current (html) buffer in a new tab (for displaying the html file the first time) and another function to open that same current buffer in the same tab (for displaying the html file subsequent times). You don't say which browser you want to do this with and, of course, the emacs function is going to need to know this (unless you use an environmental variable to designate it, in which case you'll need to determine what that is). In addition, you'll need to know which version of that browser (whichever it is) you have. I've been using firefox for quite a time and often, when I upgrade it, the command for loading a url into an existing tab or into a new tab changes; of course this means I have to alter my emacs/html-helper-mode function. In short, the first thing to do is to find out what the commands work from your shell to open a new- or a current-tab (or window, if that's what you prefer) in your browser and give it a url. Then, after you've successfully done these from the cli, then plug these into an emacs function. The cli input which works for me to open a file in a new tab is: /usr/bin/firefox -new-tab [url] Other commands work also. Much depends on what your firefox defaults are. One configuration I have is to "open new urls in a new tab"; this (for some silly reason) prevents me from opening a url in the current firefox tab. It didn't always do this; earlier Firefox versions had an option to open a url in a current tab. The lesson from this is that what cli command you use is going to depend upon, not just which browser you use, but also which *version* of that browser as well as what preferences you've set for that browser/version. You also didn't say which OS you're using and that can of course play a role in which command you'll plug into your emacs function. Anyway, once you figure out what command(s) do(es) what you want, plug it into: ;;Works for opening a file in a new firefox tab (defun browse-file-url-firefox-new-tab (url &optional new-window) "Open the current file, the file associated with the current buffer, in a new Firefox tab." (interactive "i") (unless (string= "" (shell-command-to-string (concat "firefox -a firefox -remote 'openURL(file://" buffer-file-name ", new-tab)'"))) (message "Opening in Firefox new tab: " buffer-file-name))) (setq browse-url-browser-function 'browse-file-url-firefox-new-tab) Just change the "(concat ..." line to reflect the cli command which works for you. Since firefox (nonsensically) did away with a command-line option for opening a url in a current tab, I now have to change focus to firefox and reload the tab to show any editing I've done (in emacs) since previously displaying it in firefox. (If anyone here has the ear of a firefox developer, tell them to gives us back the "-current-tab" option.) hth, ken -- War is a failure of the imagination. --William Blake On 09/03/2009 06:47 AM rpd wrote: > Hi > Just encountered this problem previewing html editing in emacs. > When I edit html (I have html-helper-mode file loaded) I want to preview it > in my browser but cannot yet do so.
