Go linter that checks if your code uses short syntax for if-statements whenever possible.
For example, it will suggest changing this code:
func someFunc(k string, m map[string]interface{}) {
_, ok := m[k]
if !ok {
return
}
err := otherFunc1()
if err != nil {
otherFunc2(err)
}
}to this:
func someFunc(k string, m map[string]interface{}) {
if _, ok := m[k]; !ok {
return
}
if err := otherFunc1(); err != nil {
otherFunc2(err)
}
}At the same time, it won't suggest any changes if a variable referenced in the if-statement also occurs in other places. E.g, linter won't complain about either of the snippents below:
func someFunc() {
err := otherFunc1()
if err != nil {
otherFunc2(err)
}
otherFunc3(err) // Variable referenced in a call outside the if-statement.
}func someFunc() {
sliceOfStrings := getSliceOfStrings()
if sliceOfStrings == 1 && sliceOfStrings[0] == "" {
return
}
for _, s := range sliceOfStrings { // Variable referenced in a loop.
// do stuff
}
}etc.
