Code Inspections in Go Template

This topic lists all GoLand code inspections available in Go Template.

You can toggle specific inspections or change their severity level on the Editor | Inspections page of the IDE settings Ctrl+Alt+S.

Inspection	Description	Default Severity
Duplicate variable	Reports duplicate Go Template variables that are declared in the same scope. Duplicating a variable reassigns the existing variable with the same name. This operation might lead to different unpredictable issues. Example: {{$v := 0}}{{$v := 1}}{{$v}} is 0. {{/* evaluates to '1 is 0' /}} {{$v := 0}}{{$w := 1}}{{$v}} is 0. {{/ works as expected */}}	Error
Unknown variable	Reports usages of unknown variables in Go Templates. Parsing of such templates will cause panic because variables must be declared before usage. Example: {{$v}} is zero. {{/* bad, $v is unknown /}} {{$v := 0}}{{$v}} is zero. {{/ good */}}	Error

{{$v := 0}}{{$w := 1}}{{$v}} is 0. {{/* works as expected */}}

Error
