# rflgo
[](https://pkg.go.dev/github.com/dalikewara/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:
```bash
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:
```go
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(),
},
}
```
```json
[{"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`:
```go
type roleDest struct {
Permission string
}
type userDest struct {
Name string
Roles *[]roleDest
}
var d []*userDest
```
you can compose it with `rflgo.Compose()`:
```go
err := rflgo.Compose(&d, s)
if err != nil {
panic(err)
}
```
then the `d` will be the same as shown bellow:
```go
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",
},
},
},
}
```
```json
[{"Name":"johndoe","Roles":[{"Permission":"create"}]},{"Name":"dalikewara","Roles":[{"Permission":"create"}]}]
```
