Re: font-lock and ruby mode

As Norbert reported in the message: http://list-archive.xemacs.org/xemacs-beta/200104/msg00301.html font-lock doesn't work well with ruby-mode because it uses a special form of keyword in `font-lock-syntactic-keywords' (setq font-lock-syntactic-keywords '(("\\$\\([#\"'`$\\]\\)" 1 (1 . nil)) ("\\(#\\)[{$＠]" 1 (1 . nil)) ("\\(/\\)\\([^/\n]\\|\\\\/\\)*\\(/\\)" (1 (7 . ?')) (3 (7 . ?'))))) `font-lock-apply-highlight' function chokes on the last keyword: ("\\(/\\)\\([^/\n]\\|\\\\/\\)*\\(/\\)" (1 (7 . ?')) (3 (7 . ?'))) Please describe exactly what actions triggered the bug and the precise symptoms of the bug: - open a new file, say ~/tmp/sample.rb - load ruby-mode and enable it - start editing ~/tmp/sample.rb: '/test/' As long as the second forward slash is entered XEmacs popups an error message: "(warning/warning) Error caught in `font-lock-pre-idle-hook': (malformed-list ?\')" However, if I disable font-lock and then enable it again, problem goes away for this buffer.
