type Test interface { T(a int) (int64, []*int, error) }

// +ioc:autowire=true // +ioc:autowire:type=singleton type TestImpl1 struct { }

func (t *TestImpl1) T(a int) (int64, []*int, error) { return 0, nil, nil }

使用 iocli gen后的zz_generated.ioc.go文件，如下：

//go:build !ignore_autogenerated // +build !ignore_autogenerated

// Code generated by iocli, run 'iocli gen' to re-generate

问题： TestImpl3未正确生成对应函数签名，结果为空结构体。

@T-Manson 方法名需要写成一行才能识别到，这是个问题，后面会修

👌

@photowey How is going on with ast analysis of iocli ? I want to refactor codes and structure of iocli recently, and I'm worry about conflicts with your contribution.

解析占据多行的函数，如果覆盖全部写法，需要引入语法分析，这个能力可能要暂时被搁置了。目前只支持单行方法名解析，合法的方法签名所在行例如：

valid line is like
func (s *ServiceStruct) GetString(name string, param *substruct.Param) string {
func (s *ServiceStruct) GetString(param *substruct.Param) string {
func (s *ServiceStruct) GetString(name, param *substruct.Param) (string, error) {
func (s *ServiceStruct) GetString() string {
func (s *ServiceStruct) GetString()  {
