Duplicate variable

Last modified: 03 December 2024

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 unpredicatable issues.

Example:

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