What did you do?
I have written a simple program. It contains variables that are defined but not used. It can be successfully compiled to executable program, but when I load the package with golang analysis tool, I get the error that it is defined but not used.
package main
import (
"fmt"
"golang.org/x/tools/go/packages"
)
func main() {
rootDir := "/tmp/example"
cfg := &packages.Config{
Mode: packages.LoadAllSyntax,
Tests: false,
Dir: rootDir,
}
packageArr, _ := packages.Load(cfg)
fmt.Printf("pkg err : %+v", packageArr[0].Errors)
}err output
pkg err : [/tmp/example/main.go:11:4: vv declared but not used]
What did you expect to see?
I would like to see a consistent behavior of the compilation tools, either fail or both succeed.
What did you see instead?
inconsistent results
