about

Use this mode for editing files in the dot-language (www.graphviz.org and
http://www.research.att.com/sw/tools/graphviz/).

To use graphviz-dot-mode, add 
(load-file "PATH_TO_FILE/graphviz-dot-mode.el") 
to your ~/.emacs(.el) or ~/.xemacs/init.el

The graphviz-dot-mode will do font locking, indentation, preview of graphs
and eases compilation/error location. There is support for both GNU Emacs
and XEmacs.

Font locking is automatic, indentation uses the same commands as
other modes, tab, M-j and C-M-q.  Insertion of comments uses the
same commands as other modes, M-; .  You can compile a file using
M-x compile or C-c c, after that M-x next-error will also work.
There is support for viewing an generated image with C-c p.

Todo:
* cleanup the mess of graphviz-dot-compilation-parse-errors.
* electric indentation is fundamentally broken, because 
{...} are also used for record nodes. You could argue, I suppose, that 
many diagrams don't need those, but it would be worth having a note (and 
it makes sense that the default is now for electric indentation to be 
off).
* lines that start with # are comments, lines that start with one or more
whitespaces and then a # should give an error.

History:

Version 0.3.7 Tim Allen
09/03/2011: * fix spaces in file names when compiling
Version 0.3.6 maintenance
19/02/2011: * .gv is the new extension  (Pander)
* comments can start with # (Pander)
* highlight of new keywords (Pander)
Version 0.3.5 bug (or at least feature I dislike) fix             
11/11/2010:  Eric Anderson http://www.ece.cmu.edu/~andersoe/
* Preserve indentation across blank (whitespace-only) lines
Version 0.3.4 bug fixes
24/02/2005: * fixed a bug in graphviz-dot-preview
Version 0.3.3 bug fixes
13/02/2005: Reuben Thomas &lt;rrt AT sc3d.org&gt;
* add graphviz-dot-indent-width
Version 0.3.2 bug fixes
25/03/2004: Rubens Ramos &lt;rubensr AT users.sourceforge.net&gt;
* semi-colons and brackets are added when electric
behaviour is disabled.
* electric characters do not behave electrically inside
comments or strings.
* default for electric-braces is disabled now (makes more
sense I guess).
* using read-from-minibuffer instead of read-shell-command
for emacs.
* Fixed test for easymenu, so that it works on older
versions of XEmacs.
* Fixed indentation error when trying to indent last brace
of an empty graph.
* region-active-p does not exist in emacs (21.2 at least),
so removed from code
* Added uncomment menu option
Version 0.3.1 bug fixes
03/03/2004: * backward-word needs argument for older emacs
Version 0.3 added features and fixed bugs
10/01/2004: fixed a bug in graphviz-dot-indent-graph
08/01/2004: Rubens Ramos &lt;rubensr AT users.sourceforge.net&gt;
* added customization support
* Now it works on XEmacs and Emacs
* Added support to use an external Viewer
* Now things do not break when dot mode is entered
when there is no buffer name, but the side effect is
that in this case, the compilation command is not
correct.
* Preview works on XEmacs and emacs.
* Electric indentation on newline
* Minor changes to indentation
* Added keyword completion (but could be A LOT better)
* There are still a couple of ugly hacks. Look for 'RR'.

11/11/2002: added preview support.
10/11/2002: indent a graph or subgraph at once with C-M-q.
