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 <rrt AT sc3d.org> -;; * add graphviz-dot-indent-width -;; Version 0.3.2 bug fixes -;; 25/03/2004: Rubens Ramos <rubensr AT users.sourceforge.net> -;; * 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 <rubensr AT users.sourceforge.net> -;; * 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.
