5041 | ------------------------------ | |
5042 | ||
5043 | Before reporting a bug, please verify that it is related to Viper, and is | |
5044 | not cause by other packages you are using. | |
5045 | ||
5046 | Don't report compilation warnings, unless you are certain that there is a | |
3af0304a | 5047 | problem. These warnings are normal and unavoidable. |
d5e52f99 MK |
5048 | |
5049 | Please note that users should not modify variables and keymaps other than | |
3af0304a | 5050 | those advertised in the manual. Such `customization' is likely to crash |
d5e52f99 MK |
5051 | Viper, as it would any other improperly customized Emacs package. |
5052 | ||
5053 | If you are reporting an error message received while executing one of the | |
5054 | Viper commands, type: | |
5055 | ||
5056 | M-x set-variable <Return> debug-on-error <Return> t <Return> | |
f1097063 | 5057 | |
3af0304a MK |
5058 | Then reproduce the error. The above command will cause Emacs to produce a |
5059 | back trace of the execution that leads to the error. Please include this | |
d5e52f99 MK |
5060 | trace in your bug report. |
5061 | ||
5062 | If you believe that one of Viper's commands goes into an infinite loop | |
5063 | \(e.g., Emacs freezes\), type: | |
5064 | ||
5065 | M-x set-variable <Return> debug-on-quit <Return> t <Return> | |
f1097063 | 5066 | |
3af0304a MK |
5067 | Then reproduce the problem. Wait for a few seconds, then type C-g to abort |
5068 | the current command. Include the resulting back trace in the bug report. | |
