The boolcmp tool is a static analysis tool for Go that detects variables with bool values that use comparison operators, and reports them as potentially simplifiable.
$ go install github.com/kyosu-1/boolcmp
$ go vet -vettool=$(which boolcmp) path/to/your/package
Consider the following Go code:
package main
func main() {
var a bool = true
if a == true {
// do something
}
}The boolcmp tool will detect the comparison a == true and report it as a warning. The output might look something like this:
main.go:5:10: bool value used in comparison
The warning indicates that the comparison a == true can be simplified to just a. This can make the code more concise and easier to read, since the comparison with true is unnecessary.
