Getting a lint warning ineffectual assignment to "cfg" at line cfg := &utils.Config{}. Why is that ?
cfg := &utils.Config{}
env := os.Getenv("TEST")
if strings.EqualFold(env, "INT") {
cfg = utils.GetIntConfig()
} else {
cfg = utils.GetConfig()
}
cgw.Cgw(cfg)
After the following if statement, cfg is written, thus the value assigned to cfg using cfg := &utils.Config{} is never used. You are using an assignment where a declaration would do.
var cfg *utils.Config
...
var cfg *utils.Config worked. Thanks. It was needed a declaration only.
var declaration; instead it hinted at that you might have a bug in your code—because the first assignment could be way more involved like assigning the return value of some function call which would return a value inintialized in a complicated way, and possibly depending on some input data.
ineffectual assignment to "cfg"means that the assignment to cfg has no effect, as you unconditionaly overwrite it later.
