4959 | ||
4960 | Before reporting a bug, please verify that it is related to Viper, and is | |
db9e401b | 4961 | not caused by other packages you are using. |
d5e52f99 MK |
4962 | |
4963 | Don't report compilation warnings, unless you are certain that there is a | |
3af0304a | 4964 | problem. These warnings are normal and unavoidable. |
d5e52f99 MK |
4965 | |
4966 | Please note that users should not modify variables and keymaps other than | |
3af0304a | 4967 | those advertised in the manual. Such `customization' is likely to crash |
d5e52f99 MK |
4968 | Viper, as it would any other improperly customized Emacs package. |
4969 | ||
4970 | If you are reporting an error message received while executing one of the | |
4971 | Viper commands, type: | |
4972 | ||
4973 | M-x set-variable <Return> debug-on-error <Return> t <Return> | |
f1097063 | 4974 | |
3af0304a MK |
4975 | Then reproduce the error. The above command will cause Emacs to produce a |
4976 | back trace of the execution that leads to the error. Please include this | |
d5e52f99 MK |
4977 | trace in your bug report. |
4978 | ||
4979 | If you believe that one of Viper's commands goes into an infinite loop | |
4980 | \(e.g., Emacs freezes\), type: | |
4981 | ||
4982 | M-x set-variable <Return> debug-on-quit <Return> t <Return> | |
f1097063 | 4983 | |
3af0304a MK |
4984 | Then reproduce the problem. Wait for a few seconds, then type C-g to abort |
4985 | the current command. Include the resulting back trace in the bug report. | |
