Things changed :
- Insert menus are now read interactively : You can put whatever you 
want in the Insert directory. You can edit it the way you want.

- fixed a bug with the editor background

- added right-click menu ( for copy, cut, paste, insert). -> If you have 
any other ideas of what to add there .... Let me know. There is still 
plenty of room

- added a popup that shows up when the user attempts to save a file in a 
folder where (s)he has no writing permissions.

Hi Fabien, 

I havn't got round to trying this or the last versions yet, but will make
some time over the next few days and have a go.  

The new changes sound interesting, can we change the editor background 
colour now?  

But dont' get any ideas, I'm still going to use emacs forever:-)

Yes there can be way to go around this, but when I use POV I don't want 
to spend half a day learning how emacs work.

I might start flames, but the way I see it, emacs may do many things, 
but it does not mean that all those things are done right.

Well, of course no one is forcing you to use emacs but your arguments are
mostly not correct:

- controlling the render options from the editor is not really an argument
for most people, using the command line is often more convenient and there
are also tools like:

http://www.zeropps.uklinux.net/linstuff.html#POVMENU

- Auto completition works (and is context sensitive, much more
sophisticated than in WinPOV!) Just use something like:

(define-key pov-mode-map "\M-\r" 'pov-complete-word)

(by default it's "\M-\t" IIRC which might not work because used by the
system)

- syntax highlighting works too (just needs to be activated probably)

- the render stats (as well as the image) can be accessed too of course
when the internal render function is used, a new buffer is created
containing the text output.

And more important than all this is of course that emacs has a lot of
standard editing functions some other editors (and pyvon) lack like:

- customizable auto indention
- sophisticated search function
- standard navigation functions (move forward/backward word, line,
paragraph, ...)
- standard deletion functions (delete word, line, ...)
- find matching braces.

I use PovMenu as my POV command line manager, and as for emacs, well as
Christof has explained, you probably don't have it set up correctly, 
have it use PC keys for selecting, copying and pasting etc with:

(pc-selection-mode)

in your .emacs file, and when it comes to altering the colours of the 
syntax highlighting I go to the xxxx.el file such as pov-mode.el or 
perl.el or html.el or whatever it is that I want to change.   I use 
emacs for all source editing, POV, perl, HTML, C and Bash, and for any
large editing jobs like utility documentation and that kind of thing. 

The only thing I don't use emacs for is writing news and mail messages,
and for that I use Pico because it loads so fast, (actually emacs run 
with -nw opens just as fast, I may consider switching). 

And I don't like Xemacs, though I do run a copy of gnu emacs that opens
it's own window (but this is not Xemacs).  I tryed Xemacs in a previous
life, I don't even have it on this machine.  

The emacs FAQ is very useful:

     http://www.lerner.co.il/emacs/
    and
      ftp://ftp.lerner.co.il/pub/emacs/
    and
      ftp://rtfm.mit.edu/pub/usenet/comp.emacs/
      ftp://ftp.uni-paderborn.de/pub/doc/FAQ/comp/emacs/

Also I like to look into the usenet group gnu.emacs.help now and again. 

I am currently using version:

GNU Emacs 20.5.1

Which is about four years old but still does the bizz. 

I can also write macros in my .emacs file, for example there's a project
I've been working on which requires me to delete the first three 
characters of the first line of a paragra, delete the first two characters
of the second line of the paragraph and then block justify tha paragraph and
move the cursor to the beginning of the next paragraph, so I can do that with 
one button press:

(global-set-key [f8] "\C-d\C-d\C-d\C-n\C-d\C-d\M-1\M-q\C-a\M-}\C-n")

It also works nicely with RCS and CVS, can work accross networks and the 
net without any problems, can act as an ftp client, telnet client or even
as a shell.  It's directory management tools can be quite nice, and it's 
got a built in calandar and diary. 

If you want any help with the .emacs file let me know and I can post mine,
or have a look at some examples and pinch some ideas for emacs from:

http://www.dotfiles.com/index.php3?app_id=6   

and for Xemacs:

http://www.dotfiles.com/index.php3?app_id=7

There's just a few reasons why I like emacs:-)

Ok, I'll try these settings, but why isn't it written in the 
installation instructions ?

Yet I followed the instructions.

This feature will be added in a future version of Pyvon

What more than (find), (find next), (replace) and (replace all) do you 
want in a search window ?

Do you mean goto line ....
When POV-RAY outputs an error, Pyvon reads the error file, goes to the 
faulty line of the script and highlights it

??? Could you tell me with which combination of keys I can have that.

This feature is already implemented by default in Pyvon

You can use regular expressions in emacs for searching and replacing.

  That's actually quite handy and I use it regularly.
  The most common search&replace which I do is to replace " +$" with "".
(If you don't know what it does, then I'll leave it as homework... :) )

  Emacs is quite ascetic by default, with really obfuscated key combination.
Also configuring it to work in a more "windows-editor-like" way requires lots
of complicated and obfuscated elisp code.
  However, once you have succeeded in configuring it the way you like, it's
really excellent.

  This is the .emacs I have configured for myself over the years. It will
work with GNU Emacs 21.* (currently I use 21.2.1). It has a couple of things
which won't work in Emacs 20.* (and there really isn't any reason to use
the older version anyways).
  I *don't* guarantee it will work with xemacs (most probably it won't), so
I suggest that you install emacs 21.* (IMHO it's better anyways). (And yes,
it will work in X and will open an X window where all colorings, key
combinations etc will work, has graphical menus, etc etc.)

  By using this .emacs file you will get lots of key combinations typical
to windows editors, automatic syntax highlighting, etc. Here is a short list
of some typical key combinations I use regularly:

  shift + cursor movement: Paint text (for copying). ("Cursor movement" means
*any* key or key combination that moves the cursor around, such as the ones
listed below.)

  Page up and page down: Move the cursor one screenful of lines up or down
(which is how it really *should* work and not how it works in emacs by
default, where it leaves the cursor in the last/first line).

  ctrl+up and ctrl+down: Scroll the screen up and down by one line.

  ctrl+left and ctrl+right: Move one word to the left and right.

  ctrl+backspace: Delete the word at the left of the cursor.

  ctrl+y: Kill the current line (which is different from ctrl+k)

  home and end: Move to the beginning and end of the line (instead of the
default emacs behaviour, which is to move to the beginning or end of the
whole file).

  ctrl+home and ctrol+end: Move to the beginning and end of the whole file.

  ctrl+ins: copy (painted text)
  shift+ins: paste
  shift+del: delete painted text

  And of course remember ctrl+_ (ie. undo) which is extremely handy.

  There are more features as well. Most of them are commented in the .emacs
itself, which is below. You should look through it and at least configure
the path to pov-mode.elc:
