|
|
4452 Before reporting a bug, please verify that it is related to Viper, and is
|
|
|
4453 not cause by other packages you are using.
|
|
|
4454
|
|
|
4455 Don't report compilation warnings, unless you are certain that there is a
|
|
|
4456 problem. These warnings are normal and unavoidable.
|
|
|
4457
|
|
|
4458 Please note that users should not modify variables and keymaps other than
|
|
|
4459 those advertised in the manual. Such `customization' is likely to crash
|
|
|
4460 Viper, as it would any other improperly customized Emacs package.
|
|
|
4461
|
|
|
4462 If you are reporting an error message received while executing one of the
|
|
|
4463 Viper commands, type:
|
|
|
4464
|
|
|
4465 M-x set-variable <Return> debug-on-error <Return> t <Return>
|
|
|
4466
|
|
|
4467 Then reproduce the error. The above command will cause Emacs to produce a
|
|
|
4468 back trace of the execution that leads to the error. Please include this
|
|
|
4469 trace in your bug report.
|
|
|
4470
|
|
|
4471 If you believe that one of Viper's commands goes into an infinite loop
|
|
|
4472 \(e.g., Emacs freezes\), type:
|
|
|
4473
|
|
|
4474 M-x set-variable <Return> debug-on-quit <Return> t <Return>
|
|
|
4475
|
|
|
4476 Then reproduce the problem. Wait for a few seconds, then type C-g to abort
|
|
|
4477 the current command. Include the resulting back trace in the bug report.
