json (mfjson)

The mfjson package provides marshal/unmarshal for objects containing interface fields
mfjson generates <file>.mfjson.go file. The file contains proxy structs for marshaling struct.

Attributes

//mfjson:interface some_name - Marks struct for add to generator with name some_name

//mfjson:add //easyjson:json - Add additional comment to proxy class

//mfjson:marshal - Mark struct as marshable with mfjson

mfjson:"true" - Marks fiels as interfacable. The field will marshal with generator

Usage

Run code gen

# install
go get -u github.com/myfantasy/json/
go install github.com/myfantasy/json/mfjson

# run
mfjson <file>.go

Code

Example for generate:

type TestInt1 interface {
	BlaName() string
}

// Generate registaration struct in generator
//mfjson:interface b_test_struct
type B struct {
	A string
	B float64
}

func (b *B) BlaName() string {
	return "B_BlaName"
}

//mfjson:add //easyjson:json
//mfjson:marshal
type Example struct {
	A int `json:"id"`
	B int64
	C TestInt1                    `json:"c" mfjson:"true"`
}

//mfjson:marshal
type AasList []TestInt1

//mfjson:add //easyjson:json
//mfjson:marshal
type AasMap map[string]TestInt1
