4766 | ||
4767 | Before reporting a bug, please verify that it is related to Viper, and is | |
4768 | not cause by other packages you are using. | |
4769 | ||
4770 | Don't report compilation warnings, unless you are certain that there is a | |
3af0304a | 4771 | problem. These warnings are normal and unavoidable. |
d5e52f99 MK |
4772 | |
4773 | Please note that users should not modify variables and keymaps other than | |
3af0304a | 4774 | those advertised in the manual. Such `customization' is likely to crash |
d5e52f99 MK |
4775 | Viper, as it would any other improperly customized Emacs package. |
4776 | ||
4777 | If you are reporting an error message received while executing one of the | |
4778 | Viper commands, type: | |
4779 | ||
4780 | M-x set-variable <Return> debug-on-error <Return> t <Return> | |
f1097063 | 4781 | |
3af0304a MK |
4782 | Then reproduce the error. The above command will cause Emacs to produce a |
4783 | back trace of the execution that leads to the error. Please include this | |
d5e52f99 MK |
4784 | trace in your bug report. |
4785 | ||
4786 | If you believe that one of Viper's commands goes into an infinite loop | |
4787 | \(e.g., Emacs freezes\), type: | |
4788 | ||
4789 | M-x set-variable <Return> debug-on-quit <Return> t <Return> | |
f1097063 | 4790 | |
3af0304a MK |
4791 | Then reproduce the problem. Wait for a few seconds, then type C-g to abort |
4792 | the current command. Include the resulting back trace in the bug report. | |
