It will work only with Emacs >= 21. ;;; The main features are fontification, line indentation (TAB) ;;; and inferior execution. The content of the the option file (by default ;;; the same name as the source but with extension .opt) will be automatically ;;; taken as NuSMV options in calling NuSMV. This feature can be turn off. ;;; As most of the features this can be customize. ;;; See the NuSMV menu -> Customize ;;; ;;; We also offer a nusmv-output-mode. In this mode you can complete ;;; NuSMV commands with the TAB key. If there is already a word on the command ;;; line TAB will complete to a file name. ;;; ;;; There is a nusmv-error-mode which use compilation-minor-mode. So a click ;;; with the middle button will lead you to the error in the source file. ;;; ;;; There is also a nusmv-m4-mode which offer only a new menu entry ;;; to expand the source file with m4. This can also be done in nusmv-mode ;;; with the command M-x nusmv-exp-with-m4 ;;; This is convenient if one use a version of NuSMV which support m4 ;;; (-m4 options). ;;; ;;; In the options file you just type in the options you would give ;;; on the command line. You can also add line-ends and comments beginning ;;; with # and they will be skipped. ;;; For more information, type C-h m in any NuSMV buffer. ;;; To use this library, place the following lines into your ~/.emacs file: ;;; ;;;; First if this file directory is not in your `load-path' ;;;; (C-h v load-path to see its value). Then add it with ;;(setq load-path (cons "THIS-FILE-PATH" load-path)) ;;;; Second make sure this NuSMV mode is loaded for any file with extension .smv ;;(autoload 'nusmv-mode "nusmv-mode" "Major mode for NuSMV specification files." t) ;;(setq auto-mode-alist ;; (append (list '("\\.smv$" . nusmv-mode)) ;; auto-mode-alist)) ;;;; load nusmv-m4-mode for any file with extension m4.smv ;;(autoload 'nusmv-m4-mode "nusmv-mode" " `nusmv-mode' with m4 support." t) ;;(setq auto-mode-alist ;; (append (list '("\\.m4.smv$" . nusmv-m4-mode)) ;; auto-mode-alist)) ;;; ;;; To load this file in any buffer type M-x load-file THIS-FILE ;;; To turn this mode on in any buffer type M-x nusmv-mode ;;; History: ;;; Sergey Berezin wrote in 1998 a major mode for writing SMV programs. ;; His mode was later modified by Marco Roveri to capture NuSMV ;;; language features (i.e. to fontify and indent NuSMV constructs). ;;; ;;; This file is a major rewrite and extension of ;;; this original SMV mode. This mode is for NuSMV and emacs 21, we ;;; don't have any specific features for SMV nor for xemacs. ;;; We kept smv-mode indentation method, for those who want to stay ;;; with it but give our own more involved method. ;;; ;;; Limitations: ;;; Compilation minor mode keeps a link only to one error for each line. ;;; So if we have a second error on a line a click on the second ;;; error message will give "No error to go to". This can happen ;;; if there is a NuSMV and m4 error on the same line. ;;; ;;; NuSMV usage message will go to the output buffer and not to the ;;; error buffer. ;;; We don't catch options errors for m4 like ;;;/usr/bin/m4: invalid option -- x ;;;Try `/usr/bin/m4 --help' for more information. ;;; They are send to the output buffer ;;; ;;; If indentation of complete file is too slow, we should define ;;; indent-region-function ;;; to be a fastest but equivalent method. ;;; ;;; The option buffer is edited in Fundamental mode. Maybe it would be ;;; more convenient to have something like customize to choose options ;;; from menus and buttons. This would help to find existing options and ;;; their meaning. ;;; ;;; Some NuSMV error messages span two lines like ;;;file bidon.smv: line 8: recursively defined: x ;;;in definition of init(x) at line 8 ;;; The first chunk will be sent to the error buffer but the second ;;; one will go to the output buffer. I don't see any simple solution. ;;; Something could be done in NuSMV. Either send only errors to standard ;;; errors (so the output of the help command would go to standard output) ;;; or make error messages formed of a single line or append something ;;; special at the beginning of the second and further errors lines. ;;; At first we developped the mode to send standard output to the ;;; output buffer and standard error to a temporary file and then to ;;; the error buffer. One cannot send both standard error and output ;;; to two different buffers in elisp. When NuSMV is interactive you ;;; must copy the errors from the file into the buffer periodically. ;;; This is not as nice as the actual implementation. ;;; ;;; Ideally in nusmv-output-mode it should be better instead of completing ;;; the first word to a command and additional words to file names, to ;;; complete additional words according to the command. This would be ;;; much more work since commands can be followed by options, numbers and ;;; file name depending of the command. ;;; ;;; With Emacs for Windows(TM) the output mode usually don't show NuSMV ;;; questions before reading the answer (examples: pick_state and simulate). ;;; This problem already arise in shell mode and seems to be due to the fact ;;; that under Windows(TM) a pipe instead of a PTTY is used to communicate ;;; with the process. ;;; See ;;; http://www.gnu.org/software/emacs/windows/faq7.html#subproc-buffer ;;; ;;; Indentation is not perfect.
