# nilerr
[![pkg.go.dev][gopkg-badge]][gopkg]
`nilerr` finds code which returns nil even though it checks that error is not nil.
```go
func f() error {
err := do()
if err != nil {
return nil // miss
}
}
```
`nilerr` also finds code which returns error even though it checks that error is nil.
```go
func f() error {
err := do()
if err == nil {
return err // miss
}
}
```
`nilerr` ignores code which has a miss with ignore comment.
```go
func f() error {
err := do()
if err != nil {
//lint:ignore nilerr reason
return nil // ignore
}
}
```
