golang自動生成setter和getter

做了一個簡單的go generate工具，從go官方工具stringer修改而來，為結構體生成setter和getter。

結構體中欄位首字母大寫預設可讀可寫，小寫則預設只讀。

可以新增access的tag，控制訪問屬性r表示讀，w表示寫，用逗號分隔。

go get gitee.com/dwdcth/accessor
新增 go:generate accessor -type=Type1,Type2
Type1,Type2表示需要生成的型別，用逗號分隔

//go:generate  accessor -type=Foo,Bar

package foobar

type Foo struct {
    ReadWrite int  `access:"r,w"`
    Write int `access:"w"`
}

type Bar struct {
    ReadWrite int
    read int
}

會生成兩個檔案，foo_accessor.go 和 bar_accessor.go
foo_accessor.go

// Code generated by "accessor -type=Foo,Bar"; DO NOT EDIT.

package foobar

func (f *Foo) SetReadWrite(param int) {
    f.ReadWrite = param
}
func (f *Foo) GetReadWrite() int {
    return f.ReadWrite
}
func (f *Foo) SetWrite(param int) {
    f.Write = param
}

bar_accessor.go

// Code generated by "accessor -type=Foo,Bar"; DO NOT EDIT.

package foobar

func (b *Bar) GetReadWrite() int {
    return b.ReadWrite
}
func (b *Bar) SetReadWrite(param int) {
    b.ReadWrite = param
}
func (b *Bar) Getread() int {
    return b.read
}
