rflgo

rflgo composes new value into destination type based on the source data value. It will reflects all values from the source, but keeps the structure, types and the properties of the destination. Both must have the same kind of type, for example, if dest int then the source must be source int.

Getting started

Installation

You can use the go get method:

go get github.com/dalikewara/rflgo

Todos

• Add support for this kind of type: map, chan, array, func

Usage

Imagine you have source s []*userSource data like this:

type roleSource struct {
    Permission string
    CreatedAt  time.Time
}
type userSource struct {
    Id        int
    Name      string
    Roles     *[]roleSource
    CreatedAt time.Time
}
r := &[]roleSource{
    {
        Permission: "create",
        CreatedAt:  time.Now(),
    },
}
s := []*userSource{
    {
        Id:        1,
        Name:      "johndoe",
        Roles:     r,
        CreatedAt: time.Now(),
    },
    {
        Id:        2,
        Name:      "dalikewara",
        Roles:     r,
        CreatedAt: time.Now(),
    },
}

[{"Id":1,"Name":"johndoe","Roles":[{"Permission":"create","CreatedAt":"2022-09-06T18:14:33.620313918+07:00"}],"CreatedAt":"2022-09-06T18:14:33.620314256+07:00"},{"Id":2,"Name":"dalikewara","Roles":[{"Permission":"create","CreatedAt":"2022-09-06T18:14:33.620313918+07:00"}],"CreatedAt":"2022-09-06T18:14:33.620314303+07:00"}]

and you want to compose the source data into this d []*userDest:

type roleDest struct {
    Permission string
}
type userDest struct {
    Name  string
    Roles *[]roleDest
}
var d []*userDest

you can compose it with rflgo.Compose():

err := rflgo.Compose(&d, s)
if err != nil {
    panic(err)
}

then the d will be the same as shown bellow:

type roleDest struct {
    Permission string
}
type userDest struct {
    Name  string
    Roles *[]roleDest
}
d := []*userDest{
    {
        Name: "johndoe",
        Roles: &[]roleDest{
            {
                Permission: "create",
            },
        },
    },
    {
        Name: "dalikewara",
        Roles: &[]roleDest{
            {
                Permission: "create",
            },
        },
    },
}

[{"Name":"johndoe","Roles":[{"Permission":"create"}]},{"Name":"dalikewara","Roles":[{"Permission":"create"}]}]
