By using the customisation interface of AUCTeX. See LaTeX menu ->  
Customize AUCTeX.

Consider to use a personalised copy of texdoc as viewer for  
everything TeX related.

Do you use AUCTeX?  Then this will do the trick.  (Replace okular with
kdvi and kpdf.)

  ;; PDFs per default mit okular öffnen
  (add-to-list 'TeX-output-view-style
               '("^pdf$" "." "okular %o"))

  ;; DVIs per default mit okular öffnen
  (add-to-list 'TeX-output-view-style
               '("^dvi$" "." "okular %o"))

I added those two to TeX-mode-hook.

Did you extend the menu? If you just were browsing, there is nothing  
obvious – and I doubt that there is a way to customise viewer options  
from this. From the expanded menu via TeX Command you can see at  
least a "TeX Output View Style" ...

Is this ease of use one of the reasons it has't yet become part of  
GNU Emacs?

Wow, my first reaction on seeing the multitude of options in the
customise auctex menu is that it's pretty user unfriendly. I have read
slowly through what was there but really nothing obvious jumped out
relating to dvi file and I can't loose a whole afternoon trying to
find that. Thanks Pete for the pointer, I'll save this one for a rainy

Thanks Peter, at least I now know what my (practical) options are. So
it looks like there's no one-liner I can just slip into my .emacs
file. Finally C-c C-c followed by replacing the x of xdvi with a k
each time doesn't seem like such a bad stratergy.

This is my impression of recent AUCTeX (11.84), too.

Once you've customised and saved, you'll be done.

Again, think of using a customised texdoc as viewer not only for TeX  
documents, but also TXT, PS, PDF, DVI – *one* tool name instead of  
four. And once your taste changes, you won't need to customise AUCTeX  
again!

OK, so finally I get it!! I have added these lines to my .bashrc

## Set defaults for texdoc
export TEXDOCVIEW_html="mozilla %s"
export TEXDOCVIEW_pdf="xpdf %s"
export TEXDOCVIEW_ps="gv %s"
export TEXDOCVIEW_dvi="kdvi %s"
export TEXDOCVIEW_txt="emacs %s"

## Create alias for texdoc. I wanted "view" as my alias name, but that
## alrady existed. So I thought about "vyew" instead. This made me
## think "vitual sheep". So the alias name is now "vs".
alias vs='texdoc -v'



Now at the shell prompt I can just type

funkyPrompt$ vs someFileName.dvi &

or 

funkyPrompt$ vs someFileName.ps &

or 

funkyPrompt$ vs someFileName.pdf &

and the right program is chosen for the job. Pretty cool. There are a
few points I still need to straighten out.

1) C-c C-c doesn't refer to texdoc. I'll have to find how to redirect
it. No no no, I got it!!! I just need to edit the entries in "tex
output view style" from the customise autex library (and hit the
"state" button). Horrah! Ah now the funny thing is I changed one of
the lines in the raised button customisation buffer to "%(o?)texdoc
%dS %d ## %(o?)xdvi %dS %d" but the environmental variable
TEXDOCVIEW_dvi as specified in .bashrc is not being used and a default
xdvi has been used instead. Doooh! Of course .bashrc has no effect on
emacs behaviour, I should think about .emacs instead right. Now with
(setenv "TEXDOCVIEW_dvi" "kdvi %s") added to .emacs C-c C-c is calling
texdoc which redirects it to kdvi!  Wola wola wola!


2) M-x *eshell* doesn't appear to read my .bashrc so the aliases and
environmental variables don't work in that shell. Well of course this
is the emacs shell and not a bash shell, but I cannot find online how
to set aliases for the eshell.


3) With M-x shell, say I forget the & I cannot use C-z followed by bg
to background the process as I could in M-x term. For a reader this
isn't a big issue, but for other applications it might be. So ...


3a) How do I get something like a terminal's C-z within *shell*?

3b) Is it possible to edit the alias I have in .bashrc such that the &
is added automatically - I tried a few things but nothing I came up
with worked.

Or just put a copy of texdoc in ~/bin and set there the preferred  
viewers.

To add an alias to eshell, you just have to set it in eshell like that:

alias ls 'ls -all'

to unset it:

alias ls

Re: Changing default dvi viewer.

[David]

Thanks for the suggestion. I was thinking of something more permanent
such as putting your lines in an initiation file, so far I haven't
managed to find how to configure the eshell such that an initiation
file is executed each time the shell is started up.

Did you try, instead of creting an alias, writing a function in .bashrc:
Some thing like that (not tested, not sure it work)

function vs
{
texdoc -v $PWD/$1
}

Yeah cool, just add the & to your function and it works great.

Re: Changing default dvi viewer.

By the way, having this above line in .bashrc is a bit strange when
texdoc is called from inside emacs becasue the txt file is opened in a
new emacs and not the current emacs.

So I am thinking to do this you nead to be able to call emacs commands
from a shell command line. Is that possible? Perhaps something like
(based on my experience with R not emacs)

aShellPrompt$ EMACS CMD Find-File %s

Use emacsclient! It needs that you first run server-start (can be  
part of ~/.emacs). Up-to-date emacsclient has many options. Be sure  
to check them (for example making it not wait for the server)! You

Once again Peter that's great. My .emacs_bash now contains

## An initialisation file just for bash inside emacs. 
## See also ~/.bashrc

export TEXDOCVIEW_txt="emacsclient %s"

This is a very bad idea since you will have to check if something
changed in texdoc every time the TeX distribution is updated unless you
don't mind missing new features and bug fixes or dealing with potential
incompatibilities.

In addition you lose the capability of passing the paper size to the
viewer.  So this is an exceptionally bad suggestion for the case at hand
where a DVI viewer is being dealt with.

It's not like there is no reason for all the options
`TeX-output-view-style'.

This isn't such a big issue. TeX Live updates happen once in two  
years, before 2006 it was once per year. We're already in the middle  
of February and no TeX Live 2008 DVD has been announced yet. I had to  
update my texdoc copy in four years once (I have saved the elder  
version in ~/bin, last change: a few days before summer 2007 began).

The latter is true, and I did not emphasise enough that David should  
only change one xdvi entry with texdoc (it is so obvious to me), the  
one that uses his default paper size. This is my fault! Next time  
I'll try to do a better job.

This xdvi incapability can be a much smaller problem when TeX users  
would understand that they are using pdfTeX, and that the DVI output  
is necessary only in just a few cases with use of special packages,  
mostly related with PostScript graphics. When TeX users would allow  
pdfTeX to directly create PDF, then the PDF viewer would not need to  
be told the paper size or its direction, because this is recorded in  
the PDF file, and then a dozen of different xdvi calls would not be  
necessary.

Anyway, once the error of changing too much was done, the original  
setup can easily be re-established by just commenting the  
customisation. Now one is offered another chance to make just the  
necessary changes, and after saving this, one can look at both  
customisation expressions and try to find an optimum. And for this  
one can "expand" the one-liners to multi-liners to see which  
expression matches which case.

What you are suggesting is just plain unnecessary because there are
other ways of achieving the goal of abusing `texdoc' as a replacement
for `run-mailcap' (aka `see'), namely setting the environment variables
used by `texdoc' or adapting the mailcap configuration.  Please, inform
yourself before making suggestions.

And how would that help?  Then he still gets `xdvi' for the other cases.
Just do `M-x customize-variable <RET> TeX-output-view-style <RET>',
search for instances of "xdvi" and replace them with "kdvi", assuming
`kdvi' takes the same command line options as `xdvi'.  Big deal!
