go-structbyname

source code generator to create a instance of struct by name in golang.

##Usage $ go run generate.go -pd [project root directory]

###Options

• -pd : project root directory (required)
• -pr : package root (optional)
• -o : output file (optional: ./mystructs/structs.go)
• -d : target directory to parse (optional: ./)
• -L : line separetor u: LF, w: CRLF, default: auto detect (optional)

If you run the generate command, mystructs/structs.go is created. You can get an instance of the structure by importing mystructs pacakge, and by executing mystruct.New function with the structure name.

###Simple Implementation

package main

import (
	"fmt"
	"reflect"

	"./mystructs"
)

func main() {
	structName := "github.com/taknb2nch/go-structbyname/sample/action.My1Action"
	methodName := "Index1"

	a1, ok := mystructs.New(structName)
	if !ok {
		fmt.Printf("%s is not found.", structName)
		return
	}

	v := reflect.ValueOf(a1)
	m := v.MethodByName(methodName)

	if !m.IsValid() || m.IsNil() {
		fmt.Printf("%s.%s is not found.", structName, methodName)
		return
	}

	vs := m.Call([]reflect.Value{
		reflect.ValueOf("aaa"),
	})

	for _, vss := range vs {
		fmt.Println(vss)
	}
}

##Sample There is a sample in sample directory. mystructs and structs.go are created by generator.
If you try,

1. delete mystructs directory
2. execute generator.
   $ go run generate.go -pd ./sample
3. execute main
   $ go run ./sample/main.go
