-## Module annotations
+## Annotations
-* `app_version` specifies the version of the generated APK file.
-It takes 3 arguments: the major, minor and revision version numbers.
-The special function `git_revision` will use the prefix of the hash of the
-latest git commit. The default version is 1.0.
+* All _app.nit_ annotations are applied to Android projects:
+ `app_name`, `app_namespace` and `app_version`.
- Example: `app_version(1, 0, git_revision)`
-
-* `app_name` takes a single argument, the visible name of the Android
-application. By default, the compiler would use the name of the target
-module. This name will be used as the name of the main activity and
-as the launcher name.
-
- Example: `app_name "My App"`
-
-* `app_namespace` specifies the package used by the generated Java
-classes and the APK file. Once the application is published, this
-value should not be changed. By default, the compiler will use
-the package `org.nitlanguage.{module_name}`.
+ See: `../app/README.md`
* Custom information can be added to the Android manifest file
using the annotations `android_manifest`, `android_manifest_application`
android_manifest """<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>"""

+_app.nit_ is a framework to create cross-platform applications
+
+The framework provides services to manage common needs of modern mobile applications:
+
+* Life-cycle
+* User interface
+* Persistence
+* Package metadata
+* Compilation and packaging
+
+The features offered by _app.nit_ are common to all platforms, but
+may not be available on all devices.
+
+## Application Life-Cycle
+
+The _app.nit_ application life-cycle is compatible with all target platforms.
+It relies on the following sequence of events, represented here by their callback method name:
+
+1. `on_create`: The application is being created.
+ You should build the UI at this time.
+
+2. `on_start`: The app is starting or restarting, background activities may
+
+3. `on_resume`: The app enters the active state, it is in the foreground.
+
+4. `on_pause`: The app leaves the active state and the foreground.
+ It may still be visible in the background.
+ It may then go back to `on_resume` or `on_stop`.
+
+5. `on_stop`: The app is completely hidden.
+ It may then be destroyed (`on_destroy`) or go back to `on_start`.
+
+6. `on_destroy`: The app is being destroyed.
+
+Life-cycle events related to saving and restoring the application state are provided by two special callback methods:
+
+* `on_save_state`: The app may be destroyed soon, save its state for a future `on_restore_state`.
+ More on how it can be done in the `app::data_store` section.
+
+* `on_restore_state`: The app is launching, restore its state from a previous `on_save_state`.
+
+These events are synchronized to the native platforms applications
+The `App` instance is the first to be notified of these events.
+Other UI elements, from the `ui` submodule, are notified of the same events using a simple depth first visit.
+So all UI elements can react separately to live-cycle events.
+
+## User Interface
+
+The `app::ui` module defines an abstract API to build a portable graphical application.
+The API is composed of interactive `Control`s, visible `View`s and an active `Window`.
+
+Here is a subset of the most useful controls and views:
+
+* The classic pushable `Button` with text (usually rectangular).
+
+* `TextInput` is a field for the user to enter text.
+
+* `HorizontalLayout` and `VerticalLayout` organize other controls in order.
+
+Each control is notified of input events by callbacks to `on_event`.
+All controls have observers that are also notified of the events.
+So there is two ways to customize the behavior on a given event:
+
+* Create a subclass of the wanted `Control`, let's say `Button`, and specialize `on_event`.
+
+* Add an observer to a `Button` instance, and implement `on_event` in the observer.
+
+### Usage Example
+
+The calculator example (at `../../examples/calculator/src/calculator.nit`) is a concrete,
+simple and complete use of the _app.nit_ portable UI.
+
+### Platform-specific UI
+
+You can go beyond the portable UI API of _app.nit_ by using the natives services of a platform.
+
+The suggested approach is to use platform specific modules to customize the application on a precise platform.
+This module redefine `Window::on_start` to call the native language of the platform and setup a native UI.
+
+_TODO complete description and add concrete examples_
+
+## Persistent State with data\_store
+
+_app.nit_ offers the submodule `app::data_store` to easily save the application state and user preferences.
+The service is accessible by the method `App::data_store`. The `DataStore` itself defines 2 methods:
+
+* `DataStore::[]=` saves and associates any serializable instances to a `String` key.
+Pass `null` to clear the value associated to a key.
+
+* `DataStore::[]` returns the object associated to a `String` key.
+It returns `null` if nothing is associated to the key.
+
+### Usage Example
+
+~~~
+import app::data_store
+
+redef class App
+ var user_name: String
+
+ redef fun on_save_state
+ do
+ app.data_store["first run"] = false
+ app.data_store["user name"] = user_name
+
+ super # call `on_save_state` on all attached instances of `AppComponent`
+ end
+
+ redef fun on_restore_state
+ do
+ var first_run = app.data_store["first run"]
+ if first_run != true then
+ print "It's the first run of this application"
+ end
+
+ var user_name = app.data_store["user name"]
+ if user_name isa String then
+ self.user_name = user_name
+ else self.user_name = "Undefined"
+
+ super
+ end
+end
+~~~
+
+## Metadata annotations
+
+The _app.nit_ framework defines three annotations to customize the application package.
+
+* `app_name` takes a single argument, the visible name of the application.
+ This name is used for launchers and window title.
+ By default, the name of the target module.
+
+* `app_namespace` specifies the full namespace (or package name) of the application package.
+ This value usually identify the application uniquely on application stores.
+ It should not change once the application has benn published.
+ By default, the namespace is `org.nitlanguage.{module_name}`.
+
+* `app_version` specifies the version of the application package.
+ This annotation expects at least one argument, usually we use three version numbers:
+ the major, minor and revision.
+ The special function `git_revision` will use the prefix of the hash of the latest git commit.
+ By default, the version is 0.1.
+
+### Usage Example
+
+~~~
+module my_module is
+ app_name "My App"
+ app_namespace "org.example.my_app"
+ app_version(1, 0, git_revision)
+end
+~~~
+
+## Compiling and Packaging an Application
+
+The Nit compiler detects the target platform from the importations and generates the appropriate application format and package.
+
+Applications using only the portable services of _app.nit_ require some special care at compilation.
+Such an application, let's say `calculator.nit`, does not depend on a specific platform and use the portable UI.
+The target platform must be specifed to the compiler for it to produce the correct application package.
+There is two main ways to achieve this goal:
+
+* The the mixin option (`-m path`) loads an additionnal module before compiling.
+ It can be used to load platform specific implementations of the _app.nit_ portable UI.
+
+ ~~~
+ # GNU/Linux version, using GTK
+ nitc calculator.nit -m NIT_DIR/lib/linux/ui.nit
+
+ # Android version
+ nitc calculator.nit -m NIT_DIR/lib/android/ui/
+ ~~~
+
+* A common alternative for larger projects is to use platform specific modules.
+ Continuing with the `calculator.nit` example, it can be accompagnied by the module `calculator_linux.nit`.
+ This module imports both `calculator` and `linux::ui`, and can also use other GNU/Linux specific code.
+
+ ~~~
+ module calculator_linux
+
+ import calculator
+ import linux::ui
+ ~~~
