5055 | ------------------------------ | |
5056 | ||
5057 | Before reporting a bug, please verify that it is related to Viper, and is | |
5058 | not cause by other packages you are using. | |
5059 | ||
5060 | Don't report compilation warnings, unless you are certain that there is a | |
3af0304a | 5061 | problem. These warnings are normal and unavoidable. |
d5e52f99 MK |
5062 | |
5063 | Please note that users should not modify variables and keymaps other than | |
3af0304a | 5064 | those advertised in the manual. Such `customization' is likely to crash |
d5e52f99 MK |
5065 | Viper, as it would any other improperly customized Emacs package. |
5066 | ||
5067 | If you are reporting an error message received while executing one of the | |
5068 | Viper commands, type: | |
5069 | ||
5070 | M-x set-variable <Return> debug-on-error <Return> t <Return> | |
f1097063 | 5071 | |
3af0304a MK |
5072 | Then reproduce the error. The above command will cause Emacs to produce a |
5073 | back trace of the execution that leads to the error. Please include this | |
d5e52f99 MK |
5074 | trace in your bug report. |
5075 | ||
5076 | If you believe that one of Viper's commands goes into an infinite loop | |
5077 | \(e.g., Emacs freezes\), type: | |
5078 | ||
5079 | M-x set-variable <Return> debug-on-quit <Return> t <Return> | |
f1097063 | 5080 | |
3af0304a MK |
5081 | Then reproduce the problem. Wait for a few seconds, then type C-g to abort |
5082 | the current command. Include the resulting back trace in the bug report. | |
