4901 | PLEASE FOLLOW THESE PROCEDURES | |
4902 | ------------------------------ | |
4903 | ||
4904 | Before reporting a bug, please verify that it is related to Viper, and is | |
4905 | not cause by other packages you are using. | |
4906 | ||
4907 | Don't report compilation warnings, unless you are certain that there is a | |
3af0304a | 4908 | problem. These warnings are normal and unavoidable. |
d5e52f99 MK |
4909 | |
4910 | Please note that users should not modify variables and keymaps other than | |
3af0304a | 4911 | those advertised in the manual. Such `customization' is likely to crash |
d5e52f99 MK |
4912 | Viper, as it would any other improperly customized Emacs package. |
4913 | ||
4914 | If you are reporting an error message received while executing one of the | |
4915 | Viper commands, type: | |
4916 | ||
4917 | M-x set-variable <Return> debug-on-error <Return> t <Return> | |
f1097063 | 4918 | |
3af0304a MK |
4919 | Then reproduce the error. The above command will cause Emacs to produce a |
4920 | back trace of the execution that leads to the error. Please include this | |
d5e52f99 MK |
4921 | trace in your bug report. |
4922 | ||
4923 | If you believe that one of Viper's commands goes into an infinite loop | |
4924 | \(e.g., Emacs freezes\), type: | |
4925 | ||
4926 | M-x set-variable <Return> debug-on-quit <Return> t <Return> | |
f1097063 | 4927 | |
3af0304a MK |
4928 | Then reproduce the problem. Wait for a few seconds, then type C-g to abort |
4929 | the current command. Include the resulting back trace in the bug report. | |
