Toothpick is a scope tree based Dependency Injection (DI) library for Java.

It is a full-featured, runtime based, but reflection free, implementation of JSR 330.

//a typical Toothpick scope tree during the execution of an Android app.

       @ApplicationSingleton 
         /              |    \  
        /               |     \
       /                |      \
   @PresenterSingleton  |   Service 2
         /              | 
        /            Service 1  
       /            
Activity 1
    /   \
   /   Fragment 2
  /
Fragment 1

Toothpick is :

• pure java (and Android helped is provided: "Smoothie")
• fast, it doesn't use reflection but annotation processing
• simple, flexible, extensible & powerful, robust & tested
• thread safe
• documented & Open Source
• scope safe : it enforces leak free apps
• test oriented : it makes tests easier
• it works very well with Android or any other context based framework (such as web containers)

Hey, Android Devs, you can use TP to create MVP apps so easily !

Currently Toothpick has 2 sets of examples :

• one in pure Java
• one for Android

For Android :

#android setup using gradle 2.2.3
buildscript {
  repositories {
    jcenter()
  }
  dependencies {
    classpath 'com.android.tools.build:gradle:2.2.3'
  }
}

...

dependencies {
  compile 'com.github.stephanenicolas.toothpick:toothpick-runtime:1.1.1'
  // and for android -> compile 'com.github.stephanenicolas.toothpick:smoothie:1.1.1'
  annotationProcessor 'com.github.stephanenicolas.toothpick:toothpick-compiler:1.1.1'

  //highly recommended
  testCompile 'com.github.stephanenicolas.toothpick:toothpick-testing:1.1.1'
  testCompile 'mockito or easymock'
}

For java:

<!--java setup with maven -->
  <dependencies>
    <dependency>
      <groupId>com.github.stephanenicolas.toothpick</groupId>
      <artifactId>toothpick-compiler</artifactId>
      <version>1.1.1</version>
      <scope>compile</scope>
    </dependency>
    <dependency>
      <groupId>com.github.stephanenicolas.toothpick</groupId>
      <artifactId>toothpick-runtime</artifactId>
      <version>1.1.1</version>
      <scope>compile</scope>
    </dependency>
    
    <!-- highly recommended-->
    <dependency> 
      <groupId>com.github.stephanenicolas.toothpick</groupId>
      <artifactId>toothpick-testing</artifactId>
      <version>1.1.1</version>
      <scope>test</scope>
    </dependency>
    <dependency>
    <easymock or mockito>
    </dependency>
  </dependencies>
