* bug#5000: 23.1.50; empty string not allowed as line-prefix @ 2009-11-21 11:01 ` Carsten Dominik 2009-11-23 3:49 ` Stefan Monnier 2009-12-05 22:55 ` bug#5000: marked as done (23.1.50; empty string not allowed as line-prefix) Emacs bug Tracking System 0 siblings, 2 replies; 4+ messages in thread From: Carsten Dominik @ 2009-11-21 11:01 UTC (permalink / raw To: emacs-pretest-bug It seems that an empty string as a line prefix makes the redisplay engine choke. Test case: - open a new buffer in fundamental mode, no auto-fill-mode - insert a long line that will be wrapped for display into two or more lines. - insert the following form into the buffer, after the long line (add-text-properties (point-min) (point) '(line-prefix "")) - evaluate this form Expected result: No change in display Actual result: The formerly wrapped line is no longer wrapped but displayed as if truncate-lines had been set (it is not set) I suspect that the empty string causes the problem. A nil line-prefix property, or a non-empty string both work fine. It is possible (likely?) that the same error also occurs with wrap-prefix, but I have not tested this.

Test case: - open a new buffer in fundamental mode, no auto-fill-mode - insert a long line that will be wrapped for display into two or more lines. - insert the following form into the buffer, after the long line (add-text-properties (point-min) (point) '(line-prefix "")) - evaluate this form Expected result: No change in display Actual result: The formerly wrapped line is no longer wrapped but displayed as if truncate-lines had been set (it is not set) I suspect that the empty string causes the problem. A nil line-prefix property, or a non-empty string both work fine. It is possible (likely?) that the same error also occurs with wrap-prefix, but I have not tested this.
