-
-Iris project has been acquired by a Dubai-based startup.
-
-Both sides agree that every related public data should remain open for at least 30 days.
-
-After the period of 30 days, company has the proprietary rights to delete or transfer this repository and all its related public data forever without any warnings.
-
-The company may or may not reveal its true identity to the public.
-
-Transaction of the public domains still in-progress:
-
-- http://iris-go.com
-- https://kataras.rocket.chat/channel/iris
-
-View-accessed users can clone the current state of the project's public repositories and use without any warranties.
-
-From now on, Original Author owns a high position to the company's table.
-
-At any circumstances,
-
-Original Author keeps the creation rights.
-
-### About the future of Iris
-
-Clone the repository today because if I can't find a new lead maintainer for the [v7.2](https://github.com/kataras/iris-v7-29d) you, as community, will have to find a way to communicate about its future, the name "iris go" was taken by the company too, so it will be nice if the future main contributor change its name too, if you don't do it I will not beat you but I don't know the full company's law-plan for this, yet.
-
-All donators, without any exception, will have my support for at least 6 months (for all iris versions), we have a private room at the [chat](https://kataras.rocket.chat/channel/iris).
-
-Don't worry **I will not let you down**, we're trying to find a decent open-source contributor to continue the Iris' open-source codebase. I'm already in touch with some good gophers but **If you're willing to maintain this project** please [send](#contact) me details about your experience, general bio and your github username.
-
-**I am really thankful for all of your support to me and the community, all donations, all bug reports, all comments without any exception. I did proceeded with all my physical abilities so far but unfortunately there weren't enough for my survivor. I'm really sorry if the latest news made iris open-source community disappointed but you have to see things from my point view, I was one step before bankruptcy, I had no other choice but accept the offer.**

+# Fr, 18 August 2017 | v8.3.0
+
+Good news for devs that are used to write their web apps using the `MVC` architecture pattern.
+
+Implement a whole new `mvc` package with additional support for models and easy binding.
+
+@kataras started to develop that feature by version 8.2.5, back then it didn't seem
+to be a large feature and maybe a game-changer, so it lived inside the `kataras/iris/core/router/controller.go` file.
+However with this version, so many things are implemented for the MVC and we needed a new whole package,
+this new package is the `kataras/iris/mvc`, but if you used go 1.9 to build then you don't have to do any refactor, you could use the `iris.Controller` type alias.
+
+People who used the mvc from its baby steps(v8.2.5) the only syntactic change you'll have to do is to rename the `router.Controller` to `mvc.Controller`:
+
+Before:
+```go
+import "github.com/kataras/iris/core/router"
+type MyController struct {
+ router.Controller
+}
+```
+Now:
+```go
+import "github.com/kataras/iris/mvc"
+type MyController struct {
+ mvc.Controller
+ // if you build with go1.9 you can omit the import of mvc package
+ // and just use `iris.Controller` instead.
+}
+```
+
+### MVC (Model View Controller)
+
+
+
+From version 8.3 and after Iris has **first-class support for the MVC pattern**, you'll not find
+these stuff anywhere else in the Go world.
+
+
+Example Code
+
+
+```go
+package main
+
+import (
+ "sync"
+
+ "github.com/kataras/iris"
+ "github.com/kataras/iris/mvc"
+)
+
+func main() {
+ app := iris.New()
+ app.RegisterView(iris.HTML("./views", ".html"))
+
+ // when we have a path separated by spaces
+ // then the Controller is registered to all of them one by one.
+ //
+ // myDB is binded to the controller's `*DB` field: use only structs and pointers.
+ app.Controller("/profile /profile/browse /profile/{id:int} /profile/me",
+ new(ProfileController), myDB) // IMPORTANT
+
+ app.Run(iris.Addr(":8080"))
+}
+
+// UserModel our example model which will render on the template.
+type UserModel struct {
+ ID int64
+ Username string
+}
+
+// DB is our example database.
+type DB struct {
+ usersTable map[int64]UserModel
+ mu sync.RWMutex
+}
+
+// GetUserByID imaginary database lookup based on user id.
+func (db *DB) GetUserByID(id int64) (u UserModel, found bool) {
+ db.mu.RLock()
+ u, found = db.usersTable[id]
+ db.mu.RUnlock()
+ return
+}
+
+var myDB = &DB{
+ usersTable: map[int64]UserModel{
+ 1: {1, "kataras"},
+ 2: {2, "makis"},
+ 42: {42, "jdoe"},
+ },
+}
+
+// ProfileController our example user controller which controls
+// the paths of "/profile" "/profile/{id:int}" and "/profile/me".
+type ProfileController struct {
+ mvc.Controller // IMPORTANT
+
+ User UserModel `iris:"model"`
+ // we will bind it but you can also tag it with`iris:"persistence"`
+ // and init the controller with manual &PorifleController{DB: myDB}.
+ DB *DB
+}
+
+// Get method handles all "GET" HTTP Method requests of the controller's paths.
+func (pc *ProfileController) Get() { // IMPORTANT
+ path := pc.Path
+
+ // requested: /profile path
+ if path == "/profile" {
+ pc.Tmpl = "profile/index.html"
+ return
+ }
+ // requested: /profile/browse
+ // this exists only to proof the concept of changing the path:
+ // it will result to a redirection.
+ if path == "/profile/browse" {
+ pc.Path = "/profile"
+ return
+ }
+
+ // requested: /profile/me path
+ if path == "/profile/me" {
+ pc.Tmpl = "profile/me.html"
+ return
+ }
+
+ // requested: /profile/$ID
+ id, _ := pc.Params.GetInt64("id")
+
+ user, found := pc.DB.GetUserByID(id)
+ if !found {
+ pc.Status = iris.StatusNotFound
+ pc.Tmpl = "profile/notfound.html"
+ pc.Data["ID"] = id
+ return
+ }
+
+ pc.Tmpl = "profile/profile.html"
+ pc.User = user
+}
+
+
+/*
+func (pc *ProfileController) Post() {}
+func (pc *ProfileController) Put() {}
+func (pc *ProfileController) Delete() {}
+func (pc *ProfileController) Connect() {}
+func (pc *ProfileController) Head() {}
+func (pc *ProfileController) Patch() {}
+func (pc *ProfileController) Options() {}
+func (pc *ProfileController) Trace() {}
+*/
+
+/*
+func (pc *ProfileController) All() {}
+// OR
+func (pc *ProfileController) Any() {}
+*/
+```
+
+Iris web framework supports Request data, Models, Persistence Data and Binding
+with the fastest possible execution.
+
+**Characteristics**
+
+All HTTP Methods are supported, for example if want to serve `GET`
+then the controller should have a function named `Get()`,
+you can define more than one method function to serve in the same Controller struct.
+
+Persistence data inside your Controller struct (share data between requests)
+via `iris:"persistence"` tag right to the field or Bind using `app.Controller("/" , new(myController), theBindValue)`.
+
+Models inside your Controller struct (set-ed at the Method function and rendered by the View)
+via `iris:"model"` tag right to the field, i.e ```User UserModel `iris:"model" name:"user"` ``` view will recognise it as `{{.user}}`.
+If `name` tag is missing then it takes the field's name, in this case the `"User"`.
+
+Access to the request path and its parameters via the `Path and Params` fields.
+
+Access to the template file that should be rendered via the `Tmpl` field.
+
+Access to the template data that should be rendered inside
+the template file via `Data` field.
+
+Access to the template layout via the `Layout` field.
+
+Access to the low-level `context.Context` via the `Ctx` field.
+
+Flow as you used to, `Controllers` can be registered to any `Party`,
+including Subdomains, the Party's begin and done handlers work as expected.
+
+Optional `BeginRequest(ctx)` function to perform any initialization before the method execution,
+useful to call middlewares or when many methods use the same collection of data.
+
+Optional `EndRequest(ctx)` function to perform any finalization after any method executed.
+
+Inheritance, see for example our `mvc.SessionController`, it has the `mvc.Controller` as an embedded field
+and it adds its logic to its `BeginRequest`, [here](https://github.com/kataras/iris/blob/master/mvc/session_controller.go).
+
+**Using Iris MVC for code reuse**
+
+By creating components that are independent of one another, developers are able to reuse components quickly and easily in other applications. The same (or similar) view for one application can be refactored for another application with different data because the view is simply handling how the data is being displayed to the user.
+
+If you're new to back-end web development read about the MVC architectural pattern first, a good start is that [wikipedia article](https://en.wikipedia.org/wiki/Model%E2%80%93view%E2%80%93controller).

+### MVC
+
+
+
+Iris has **first-class support for the MVC (Model View Controller) pattern**, you'll not find
+these stuff anywhere else in the Go world.
+
+Iris web framework supports Request data, Models, Persistence Data and Binding
+with the fastest possible execution.
+
+**Characteristics**
+
+All HTTP Methods are supported, for example if want to serve `GET`
+then the controller should have a function named `Get()`,
+you can define more than one method function to serve in the same Controller struct.
+
+Persistence data inside your Controller struct (share data between requests)
+via `iris:"persistence"` tag right to the field or Bind using `app.Controller("/" , new(myController), theBindValue)`.
+
+Models inside your Controller struct (set-ed at the Method function and rendered by the View)
+via `iris:"model"` tag right to the field, i.e ```User UserModel `iris:"model" name:"user"` ``` view will recognise it as `{{.user}}`.
+If `name` tag is missing then it takes the field's name, in this case the `"User"`.
+
+Access to the request path and its parameters via the `Path and Params` fields.
+
+Access to the template file that should be rendered via the `Tmpl` field.
+
+Access to the template data that should be rendered inside
+the template file via `Data` field.
+
+Access to the template layout via the `Layout` field.
+
+Access to the low-level `context.Context` via the `Ctx` field.
+
+Flow as you used to, `Controllers` can be registered to any `Party`,
+including Subdomains, the Party's begin and done handlers work as expected.
+
+Optional `BeginRequest(ctx)` function to perform any initialization before the method execution,
+useful to call middlewares or when many methods use the same collection of data.
+
+Optional `EndRequest(ctx)` function to perform any finalization after any method executed.
+
+Inheritance, see for example our `mvc.SessionController`, it has the `mvc.Controller` as an embedded field
+and it adds its logic to its `BeginRequest`, [here](https://github.com/kataras/iris/blob/master/mvc/session_controller.go).
+
+**Using Iris MVC for code reuse**
+
+By creating components that are independent of one another, developers are able to reuse components quickly and easily in other applications. The same (or similar) view for one application can be refactored for another application with different data because the view is simply handling how the data is being displayed to the user.
+
+If you're new to back-end web development read about the MVC architectural pattern first, a good start is that [wikipedia article](https://en.wikipedia.org/wiki/Model%E2%80%93view%E2%80%93controller).
+

+- [Session Controller](mvc/session-controller/main.go)

-// Controller is the base controller for the high level controllers instances.
-//
-// This base controller is used as an alternative way of building
-// APIs, the controller can register all type of http methods.
-//
-// Keep note that controllers are bit slow
-// because of the reflection use however it's as fast as possible because
-// it does preparation before the serve-time handler but still
-// remains slower than the low-level handlers
-// such as `Handle, Get, Post, Put, Delete, Connect, Head, Trace, Patch`.
-//
-//
-// All fields that are tagged with iris:"persistence"`
-// are being persistence and kept between the different requests,
-// meaning that these data will not be reset-ed on each new request,
-// they will be the same for all requests.
-//
-// An Example Controller can be:
-//
-// type IndexController struct {
-// Controller
-// }
-//
-// func (c *IndexController) Get() {
-// c.Tmpl = "index.html"
-// c.Data["title"] = "Index page"
-// c.Data["message"] = "Hello world!"
-// }
-//
-// Usage: app.Controller("/", new(IndexController))
-//
-//
-// Another example with persistence data:
-//
-// type UserController struct {
-// Controller
-//
-// CreatedAt time.Time `iris:"persistence"`
-// Title string `iris:"persistence"`
-// DB *DB `iris:"persistence"`
-// }

-// // Get serves using the User controller when HTTP Method is "GET".
-// func (c *UserController) Get() {
-// c.Tmpl = "user/index.html"
-// c.Data["title"] = c.Title
-// c.Data["username"] = "kataras " + c.Params.Get("userid")
-// c.Data["connstring"] = c.DB.Connstring
-// c.Data["uptime"] = time.Now().Sub(c.CreatedAt).Seconds()
-// }
-//
-// Usage: app.Controller("/user/{id:int}", &UserController{

-// Title: "User page",
-// DB: yourDB,
