1.39.0 Update

Welcome to the new DeepScan updates! We hope that you are doing well in the current public health crisis.

Please kindly go ahead with the highlights for the latest release.

The following Vue.js rules are introduced:

VUE_DUPLICATE_SLOT - Do not use duplicate names in Vue slots
VUE_MISMATCHED_COUNT_OF_ARGS - Do not call Vue APIs with the wrong number of arguments
VUE_MISUSED_V_SLOT - Do not use an improper v-slot directive

The following plugins which are quite common in Vue projects are supported:

Support Vue v-slot directive
Support Vue dynamic directive argument
Detect VUE_BAD_DIRECTIVE_FORMAT alarm when v-on without an argument has modifiers
Detect VUE_BAD_PROP_DECL alarm when an object is directly used as a default value
Detect VUE_DUPLICATE_PROPERTY_IN_OPTION alarm for duplicate elements inside array-style props option
Detect VUE_MISMATCHED_TYPE_OF_ARG alarm for non-object first argument of Vue.observable()
Detect VUE_MISSING_CLEANUP_IN_LIFECYCLE alarm when handlers added at activated() lifecycle are not removed
Detect SYNTAX_ERROR alarm when multiple JS expressions connected with comma are used inside Vue template

Do not detect VUE_BAD_COMPONENT_NAME alarm for Unicode letters
Do not detect VUE_MISMATCHED_TYPE_OF_ARG alarm for null values if the argument is optional
Do not detect VUE_MISMATCHED_TYPE_OF_ARG alarm for the undefined value caused by a missing argument because it is now detected by VUE_MISMATCHED_COUNT_OF_ARGS rule

A false alarm for VUE_DUPLICATE_PROPERTY_IN_OPTION may occur for options specified with arrays
A false alarm for VUE_UNUSED_LOCAL_COMPONENT may occur if the root <template> has an src attribute
Alarm location is incorrect for attribute values without quotes inside Vue template
Alarm location and impact for VUE_DUPLICATE_ATTRIBUTE may be incorrect for v-bind directives with the same LHS parts
Analyzer may abnormally terminate when the overwriting assignments appear before UNUSED_VAR_ASSIGN alarms
