Plugin for IntelliJ IDEA that provides on the fly implementation of various design patterns.

Design Patterns IntelliJ IDEA Plugin

This plugin is meant to provide on the fly implementation of various design patterns.
You can download it directly from IntelliJ IDEA or from https://plugins.jetbrains.com/plugin/10856-design-patterns-plugin

Currently supported design patterns

• Behavioral
  • Strategy
• Creational
  • Builder (Inner)
  • Factory
  • Singleton
• Structural

How to use

Assuming you have already installed the plugin, you can use it just by right-clicking inside a .java file while your mouse is inside a code block that defines a class. This will bring up the editor menu and the first option will be Design Patterns, where you can choose which one should be implemented.

Getting started

In order to avoid some common importing errors (when it comes to intellij plugin development), please follow the steps listed below.

• Open the project using IntelliJ IDEA (Community or Ultimate)
• In Project Structure -> Project Settings -> Project -> Project SDK create a new IntellJ Platform Plugin SDK
  
  • When asked for directory, use your IntelliJ IDEA installation directory.
  • Note that you will need IntelliJ IDEA Community in order to be able to properly debug the SDK's core code. If no debug is required though, Ultimate will work just fine as well.
• In Project Language Level choose 8 - Lambdas, type annotations etc
• In Project compiler output choose the out folder (for example C:\Users\design-patterns\out
• Use gradlew runIde to run the plugin
