xml indenting, possibly with psgml?

xml indenting, possibly with psgml?

[Bjoern]

Hello,

I can't figure out how to make psgml indent my xml-files. It just 
doesn't do anything when I press 'tab' or do 'indent-region'.

I also get an error message because it doesn't find the dtd, can't I get 
rid of that. I guess I really only need indenting and possibly syntax 
highlighting.

Perhaps there is a simpler mode for achieving this?

Many thanks in advance for any help!

M-x customize-variable RET sgml-indent-data

You'll only get that error once (the first time it attempts to
parse).  You can live with it (and still derive benefit from
indentation, etc) or you can create a local CATALOG file that contains
the DTD references you commonly use.  I highly recommend this article:

Not really.

Hm, my emacs doesn't seem to know that variable :-(

The problem is that there isn't really a DTD for ant build.xml files. 
ALthough I think there now is a target to create one from a build file, 
but I am not sure if it's practical if it's constantly changing.

What does C-h v say about it?  Maybe it's a variable but not a Custom
option.

I know next to nothing about build files, but I always thought the
DTD was rather fixed.  You might wish to try the Ant command on two
different build files to see if the DTD is different.  (ant -projecthelp?)

The newer version of sgml-mode (the one bundled with Emacs) will do
just that.  You can try it out from the CVS directory.  It reportedly
works under Emacs-21.[12] as well.

That seems to work great, thanks! Apparently the version that came with 
my emacs (21.2 for win32) was buggy, which was probably why I installed 
psgml to begin with.

Now onwards trying to figure out how to make emacs indent with spaces 
only (no tabs) and how to compile the .el file (the latter should be easy).

Managed both, somehow things are working better this time than last time 
I tried.

Self-documentation adjustment

[David Forrest]

Is there a way to modify/advise the documentation strings in functions and
variables after they have been defined?

What I would be looking for would be something like the scenario:

C-h a mouse

;;; notice apropos-mouse-follow is not documented
;;; research it and then execute something like:

(document apropos-mouse-follow "Use the mouse to follow an apropos link.")

;;; and then have C-h a apropos-mouse-follow show the new documentation


apropos-mouse-follow	      <mouse-2>
  Use the mouse to follow an apropos link.


-------------------

I know I could redefine the function and edit my copy of the original
file, but I would like to be able to extend the documentation without
ham-handedly corrupting the underlying files, functions, or variables.

Thanks for your time,
Dave

Please report such missing docstrings with M-x report-emacs-bug.

PS: The above function has disappeared from Emacs so there's no need to
    report it.

Moving a symbol from one obarray to another

[Greg Hill]

My objective is to move a symbol from one obarray to another.  The 
following routine seems to do that ok.

(defun move-symbol (sym-name from-obarray to-obarray)
   "Move symbol named SYM-NAME from FROM-OBARRAY to TO-OBARRAY"
   (let ((old-sym (intern-soft sym-name from-obarray))
           (new-sym (intern sym-name to-obarray)) )
     (set new-sym (symbol-value old-sym))
     (fset new-sym (symbol-function old-sym))
     (setplist new-sym (symbol-plist old-sym))
     (unintern sym-name from-obarray) ))

My question is, is there a more efficient way to do that, e.g. 
without creating a whole new symbol and destroying the old one?

I downloaded this guy and loaded it up, but when I C-x h and C-M \ it 
doesn't seem to indent logically.  It basically indents every line 
increasingly so that they form a backwards stair-step pattern.  Any hints???

I loaded up psgml also and got nuthin' for indent-region, even after the 
set variable tricks mentioned.  I am running NTEmacs 20.7.

Didn't like the way I had to force psgml to parse the buffer b4 
font-locking either, or the way it seemed to be parsing on keystroke and 
    taking a bunch of processor overhead while just navigating the file

Of course, it is entirely possible that I do not know what I am doing. :)

Thanks,
Greg

Just like with most auto-indenting modes (well, maybe more so ;-), you have
to be careful where you break your lines.  Try to insert newlines at
various places to see what helps.  In any case, send a problematic sample to
emacs-pretest-bug@gnu.org so we can see what to do with it.

xml-lite is a minor mode which does this.
