|
|
4652 Before reporting a bug, please verify that it is related to Viper, and is
|
|
|
4653 not cause by other packages you are using.
|
|
|
4654
|
|
|
4655 Don't report compilation warnings, unless you are certain that there is a
|
|
|
4656 problem. These warnings are normal and unavoidable.
|
|
|
4657
|
|
|
4658 Please note that users should not modify variables and keymaps other than
|
|
|
4659 those advertised in the manual. Such `customization' is likely to crash
|
|
|
4660 Viper, as it would any other improperly customized Emacs package.
|
|
|
4661
|
|
|
4662 If you are reporting an error message received while executing one of the
|
|
|
4663 Viper commands, type:
|
|
|
4664
|
|
|
4665 M-x set-variable <Return> debug-on-error <Return> t <Return>
|
|
|
4666
|
|
|
4667 Then reproduce the error. The above command will cause Emacs to produce a
|
|
|
4668 back trace of the execution that leads to the error. Please include this
|
|
|
4669 trace in your bug report.
|
|
|
4670
|
|
|
4671 If you believe that one of Viper's commands goes into an infinite loop
|
|
|
4672 \(e.g., Emacs freezes\), type:
|
|
|
4673
|
|
|
4674 M-x set-variable <Return> debug-on-quit <Return> t <Return>
|
|
|
4675
|
|
|
4676 Then reproduce the problem. Wait for a few seconds, then type C-g to abort
|
|
|
4677 the current command. Include the resulting back trace in the bug report.
