#Tabbels

A crazy idea about bringing functional programming to Java, in an elegant way

Highly inspired by LUA tables, hence the play on the word Table to Tabbel; this is an attempt to represent this LUA Tables filled with pure functions, which can interact with the ecosystem without having to leave Java.

###GRADLE:

 repositories {

 ...

 maven {
 url 'https://github.com/FireZenk/maven-repo/raw/master/'
}
  
}
  dependencies {

 ...
 compile 'org.firezenk:tabbels-core:{
last_version
}
' // for java projects

 compile 'org.firezenk:tabbels-android:{
last_version
}
@aar' // for android projects  
}

###USAGE:

The simplest example in pure Java would be to create a function in a new table:

 final Tabbels ?? = create(
  ).a?(

"helloWorld", (self) -> {

 System.out.println("Hello world!");

  
}
.build();

Here is another simple case for Android based projects:

 // In your Application in order to observe the Activity lifecycle
  Tabbels.register(this);
 final Tabbels ?? = create(
  ).a?(

"onCreate", (self, bundle) -> {

 setContentView(R.layout.main_activity);

  final TextView tv = (TextView) findViewById(R.id.textView);

 tv.setText("Hello world!");

}

  ).build();

Like a functional language, you can embed and combine functions using the variable self:

 ...
  ).f?(

"sum", (self, i1, i2) -> (Integer) i1 + (Integer) i2
  ).f?(

"sum2", (self, i1, i2) -> self.f?("sum", self.f?("sum", 2, 4), 6)
  ).build();

###COMPOSITION:

Since version 1.3.0, Tabbels provides the possibility to compose tables from other tables. This is especially useful for applying design patterns in the presentation layer and enhance the functionality of our classes from other, simulating multiple inheritance :

...  ).inject(

new SomePresenter().??, new ColorHelper().??
  ).build();

###SOME IMPORTANT THINGS:

  • Note the use of or , is a function that returns something while has no return value
  • Remember to call build() at the end of the declaration
  • The implementation of Android is coupled with the life cycle of the activities ( Activity only for now)

###MORE INFO:

Go to sample module 

###NEW ON LAST VERSION (1.3.0):

  • Interconnect Tabbels using inject(Tabbels... dependency)

PeekAndPop is an open source Android library, inspired by Instagram's latest 3D touch feature. As 3D touch is not available for android, this library uses long hold.

Peek and pop allows you to long click on a view to "peek" and see a larger view in the centre of the screen. The pop feature can be imitated using fling to action gestures or from a hold and release event.

Steppers view library for Android, based on Google Material design guidelines.

Road Runner is a library for android which allow you to make your own loading animation using a SVG image.
