iocli gen问题

[T-Manson]

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
}

// +ioc:autowire=true
// +ioc:autowire:type=singleton
type TestImpl2 struct {
}

func (t *TestImpl2) T(a int) (int64, []*int, error) {
return 0, nil, nil
}

// +ioc:autowire=true
// +ioc:autowire:type=singleton
type TestImpl3 struct {
}

func (t *TestImpl3) 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

package main

if err != nil {

return impl, nil
}

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()  {
