Hi!

Using Emacs 21.3.1, the following two lines in my .emacs worked fine:

(autoload 'xsl-mode "xslide" "Major mode for XSL stylesheets." t)
(setq auto-mode-alist (cons '("\\.xsl$" . xsl-mode) auto-mode-alist))

Using Emacs 22.0.50.1, xsl-mode is only loaded automatically when 
I create a new xsl file. When I open an existing xsl file, xml 
mode is loaded instead.

Anybody an idea what's wrong?

Thanks in advance,
Markus

From the documentation of auto-mode-alist:

    See also `interpreter-mode-alist', which detects executable script modes
    based on the interpreters they specify to run,
    and `magic-mode-alist', which determines modes based on file contents.
    
I suppose you should take a look at magic-mode-alist

The only "intuitive" interface is the nipple.
After that, it's all learned

Thank you very much for your information. I now see where the 
different behaviour comes from.

By far, I'm no Emacs expert ... so, can you give me a hint in 
which way I have to modify magic-mode-alist so that xsl-mode is 
being started whenever a file with the extension ".xsl" is loaded?

In 21.x, it was a breeze for an elisp novice to copy those two 
lines and to adjust them to my needs.

Thank you very much in advance,
Markus

A question to the rest of the list: I have seen this being asked a
couple of time recently... maybe it would make sense to change default
value of magic-mode-alist to not include "xml-mode" and "html-mode" ?

It seems to me that magic-mode-alist makes sense if there is only one
mode for visiting certain type of files... and there seems to be a
couple different modes commonly used for xml and html.

Well, try this (not tested):

(push magic-mode-alist '("<\\?xml " . nil))

I am sure those better versed in elisp can suggest a nicer solution :)

I agree, auto-mode-alist is much easier to customise.

Yeap, could make sense ... the problem is that an xsl file starts
the very same way an xml file does ...

Looks fine to me, but nope, this line results into the following
error:

Wrong type argument: symbolp, (quote (<\?xml ))

But I simply altered the line a bit using "setq" instead of "push":

(autoload 'xsl-mode "xslide" "Major mode for XSL stylesheets." t)
(setq auto-mode-alist (cons '("\\.xsl$" . xsl-mode) auto-mode-alist))
(setq magic-mode-alist (cons '("<\\?xml " . nil) magic-mode-alist))

Well, I'm fine with the solution above. Elisp is pretty weird to
code if you come from C++ or Java ...

Yeap, although magic-mode-alist is certainly a nice
"intelli-sense" feature ;-)

Thanks a bunch for your help,
Markus
