xml indenting again (sgml-mode broken???)

xml indenting again (sgml-mode broken???)

[Bjoern]

*SIGH* - now that I've upgraded to emacs 21.3 (Win32) from 21.2, 
html/xml-indenting appears to be broken again (not indenting, just 
inserting LOADS of whitespace everywhere). I searched the ng archives 
and found old answers to a similiar request of mine. I think back then I 
downloaded a new version of sgml-mode and replaced the one that comes 
with emacs. However, now sgml-mode doesn't recognise comments in my 
xml-files anymore, and it complains about unmatched tags, because I have 
something like

   <!-- servlet>
	...
	</servlet>
         ...
  </servlet-mapping -->

in my file.

I tried copying the sgml-mode.el from my old emacs installation, but it 
didn't work, either (I also byte-compiled it).

What can I do now? I don't want to use psgml because of the pestering 
for DTDs.

I also need to look for a mode that can handle jsp-Files well, so 
recommendations for that would be much appreciated.

Many thanks in advance!

Get mmm-mode.  Look in the mmm-sample.el.  This has the example needed
to get you started.  From there, you should be able to make it so you
have html-helper-mode as the main mode and jde for the java sections.

Of course, you'd need to download the jde for that as well.

Thanks, I was going to check it out, but it appears that there is an
open bug saying that 'indenting sometimes doesn't work in JDE-mode' :-(

I might try it at a later time, but now I need a break (spent countless 
hours trying to configure emacs)...

I just tested HTML-HELPER-MODE, but it doesn't work, either (JDE
indenting does nothing, everything is aligned to the left). Besides, I 
don't understand the html-indenting policy of html-helper mode.

I don't use such things, so I'm not sure what sgml-mode.el should do there.
Could describe to a non-web-hacker what things can look like and how
sgml-mode.el should ideally treat them ?

It's just a section that is commented out (<!-- comment --> being the 
xml syntax for comments). I'm not sure what would be the best way to 
indent it. Perhaps the whole

	<!--
	....
	-->

block should be treated like any tag that stretches over several lines like

	<
	...
	/>

Even if you're not sure, it seems you know enough to consider the behavior
of the sgml-mode.el that you got from the CVS repository to be incorrect,
so could you describe in what way it's incorrect ?

If for example I indent the following document with M-x indent-region:

<tagxy>
     <!--
          </sometag>
-->
</tagxy>

I get the error "unmatched tags <tagxy> and </sometag>. So it seems the 
mode doesn't recognise the comments.

I hope it even is sgml-mode? It says (XML) in the Mode Bar (or what it's 
called), and is also the mode I am in after typing 'M-x sgml-mode'.

Thank you for your interest!

Could you please be more precise ?  E.g. when do you get this error ?
I can guess it's when you hit TAB, but where do you hit it ?
Does it work when you hit TAB on the last line (the one with </tagxy>) ?
Does the error lead to a bad behavior, if so which one ?
After all, just complaining about an unmatched tag is not a problem:
you can always ignore the message if you know it's groundless.
Or is it just that the message annoys you ?

[..time passes..]

I think I see what you're talking about.  If I hit TAB on the -->
line I also get the message (and it wrongly indents to column 0).
I'll see what I can do about it.  It should be able to notice the
<!-- when working its way backwards and infer that it was inside a
comment.

Sounds like we're talking about the same mode: it tries to automatically
detect whether you're using XML or SGML.

Have you ever tried xml-lite-mode?
I provides simple intending feature and a little more.
Look here for a little more description:
http://wttools.sourceforge.net/emacs-stuff/emacsandxml.html

what is wrong with psgml and DTD? Haven't you DTD for your
documents? It seems to me you still should be able to use psgml.

Yes, I've been looking for it, but I found some page saying that it has 
merged with sgml-mode now. But your link says it hasn't been merged yet?

I think the author of xml-lite has been answering in this very thread, 
so I hope there will be an easy fix for sgml-mode ;-)

I don't always have DTDs, ie for ant build.xml files, or for xml-format 
that I make up on my own and can't be bothered to also write a DTD for.

I guess there should be a way to switch off that bloody error message of 
psgml, but who knows how long it would take to find it...

What happens if you use a marked section instead:


<![IGNORE [

...

I get the same error message about unmatched tags.

sgml-mode in GNU Emacs 21.3.50 has supported indent.

You may either check it out from the CVS or download from my site:
http://61.70.221.93/stuff/sgml-mode.el

Please try the sgml-mode.el in Emacs CVS.  I've just installed a change
that should help in such cases.  I'd be happy to hear whether it works well
or not for you.

PS: In case you can't remember, the location is
http://savannah.gnu.org/cgi-bin/viewcvs/emacs/emacs/lisp/textmodes/sgml-mode.el?rev=HEAD
and you can get there by following links from savannah.gnu.org/projects/emacs.

Many thanks for your efforts! It still complains about ummatched tags. 
However, you are right, it still indents properly. The error message can 
be ignored, although it would be nice as a sort of basic validator if 
unmatched tags were detected correctly.

Maybe something else was wrong when I first got the impression that 
indenting doesn't work, though, because now also html-mode seems to 
indent correctly, which definitely wasn't the case at first.

Yes, I haven't tried to address this issue.  I think the error-reporting
is a bit too simplistic to be able to eliminate those messages (we've
already sent them out by the time we notice what's going on).
But it shouldn't be too hard to fix it and would bring more benefits (such
as better messages when they're relevant).

html-mode is also a derivative of sgml-mode and uses the same
indentation code.
