+# Deepcopier
+
+[![Build Status](https://secure.travis-ci.org/ulule/deepcopier.png?branch=master)](http://travis-ci.org/ulule/deepcopier)
+
+This package is meant to make copying of structs to/from others structs a bit easier.
+
+## Installation
+
+```bash
+go get -u github.com/ulule/deepcopier
+```
+
+## Usage
+
+```golang
+// Deep copy instance1 into instance2
+Copy(instance1).To(instance2)
+
+// Deep copy instance1 into instance2 and passes the following context (which
+// is basically a map[string]interface{}) as first argument
+// to methods of instance2 that defined the struct tag "context".
+Copy(instance1).WithContext(map[string]interface{}{"foo": "bar"}).To(instance2)
+
+// Deep copy instance2 into instance1
+Copy(instance1).From(instance2)
+
+// Deep copy instance2 into instance1 and passes the following context (which
+// is basically a map[string]interface{}) as first argument
+// to methods of instance1 that defined the struct tag "context".
+Copy(instance1).WithContext(map[string]interface{}{"foo": "bar"}).From(instance2)
+```
+
+Available options for `deepcopier` struct tag:
+
+| Option    | Description                                                          |
+| --------- | -------------------------------------------------------------------- |
+| `field`   | Field or method name in source instance                              |
+| `skip`    | Ignores the field                                                    |
+| `context` | Takes a `map[string]interface{}` as first argument (for methods)     |
+| `force`   | Set the value of a `sql.Null*` field (instead of copying the struct) |
+
+**Options example:**
+
+```golang
+type Source struct {
+    Name                         string
+    SkipMe                       string
+    SQLNullStringToSQLNullString sql.NullString
+    SQLNullStringToString        sql.NullString
+
+}
+
+func (Source) MethodThatTakesContext(c map[string]interface{}) string {
+    return "whatever"
+}
+
+type Destination struct {
+    FieldWithAnotherNameInSource      string         `deepcopier:"field:Name"`
+    SkipMe                            string         `deepcopier:"skip"`
+    MethodThatTakesContext            string         `deepcopier:"context"`
+    SQLNullStringToSQLNullString      sql.NullString 
+    SQLNullStringToString             string         `deepcopier:"force"`
+}
+
+```
+
+Example:
+
+```golang
+package main
+
+import (
+    "fmt"
+ 
+    "github.com/ulule/deepcopier"
+)
+
+// Model
+type User struct {
+    // Basic string field
+    Name  string
+    // Deepcopier supports https://golang.org/pkg/database/sql/driver/#Valuer
+    Email sql.NullString
+}
+
+func (u *User) MethodThatTakesContext(ctx map[string]interface{}) string {
+    // do whatever you want
+    return "hello from this method"
+}
+
+// Resource
+type UserResource struct {
+    DisplayName            string `deepcopier:"field:Name"`
+    SkipMe                 string `deepcopier:"skip"`
+    MethodThatTakesContext string `deepcopier:"context"`
+    Email                  string `deepcopier:"force"`
+
+}
+
+func main() {
+    user := &User{
+        Name: "gilles",
+        Email: sql.NullString{
+            Valid: true,
+            String: "gilles@example.com",
+        },
+    }
+
+    resource := &UserResource{}
+
+    deepcopier.Copy(user).To(resource)
+
+    fmt.Println(resource.DisplayName)
+    fmt.Println(resource.Email)
+}
+```
