var Analyzer = &analysis.Analyzer{

Analyzer defines the linter for `emptynil` check

This linter avoids calling `fmt.Println(expr)` or `fmt.Printf(\"%s\", expr)` directly, because `Expression` doesn't implement `String()` method, so it will print the address or internal state of the expression. It handles the following function call: 1. `fmt.Println(expr)` 2. `fmt.Printf(\"%s\", expr)` 4. `fmt.Sprintf(\"%s\", expr)` 5. `(*Error).GenWithStack/GenWithStackByArgs/FastGen/FastGenByArgs`

Every struct which implemented `StringWithCtx` but not implemented `String` cannot be used as an argument.
