Package: emacs Version: 23.0.50 In the newest Emacs HEAD source, font-lock in cperl-mode is broken. Here are the steps to reproduce the problem: 1. Start emacs: $ emacs -Q 2. Visit an empty perl file and switch to cperl-mode: C-x C-f x.pl M-x cperl-mode 3. Type `print' (no any characters follow the character `t'): print| The vertical bar `|' here indicates the cursor. Now the word `print' is highlighted with face `cperl-nonoverridable-face'. 4. Now that the cursor is after the character `t', type SPC to append a whitespace character. print | This time, the word `print' gets unhighlighted. There is no property `face' for that word now: ;; Point is in between `print'. (text-properties-at (point)) ==> (fontified t) Appending more whitespace characters will not call the highlight back. However, deleting all of the whitespace characters highlights it again. print | ;; Type DEL print| ;; `print' gets highlighted again And the face property is added back: ;; Point is in between `print'. (text-properties-at (point)) ==> (face cperl-nonoverridable-face font-lock-multiline t fontified t) The same problem exists for larger Perl programs. This is only a simple case.
