Re: [Matlab-emacs-discuss] Emacs hangs with a line

[Tak K. <tak...@gm...>]

I found that Emacs freezes on following block. Do you have idea?

matlab.el:1167: (defun matlab-mode ()
...
matlab.el:1275:   (setq font-lock-defaults '((matlab-font-lock-keywords
matlab.el:1276:                   matlab-gaudy-font-lock-keywords
matlab.el:1277:                   matlab-really-gaudy-font-lock-keywords
matlab.el:1278:                   )
matlab.el:1279:                  t ; do not do string/comment highlighting
matlab.el:1280:                  nil ; keywords are case sensitive.
matlab.el:1281:                  ;; This puts _ as a word constituent,
matlab.el:1282:                  ;; simplifying our keywords significantly
matlab.el:1283:                  ((?_ . "w"))))
