Praso - A Design Pattern Detection Tool

Automatically detect software design patterns by constraint satisfaction using an interactive shell.

This project depends on Scitools Understand for generating dependency matrices. There's also a free student licence

The interactive shell uses [Ammonite](http://www.lihaoyi.com/Ammonite/ m), which not only makes it possible to run the program interatively, but brings the capabilities of scala and bash into the mix.

Install & Run

• Clone repo: git clone https://github.com/justiceo/praso-dpd
• Install JDK, Scala, SBT (if not already installed): cd praso-dpd; sudo ./install.sh
• Run: sbt run or sbt "run-main DPD.ScalaREPL"
• Run (specify dsm): sbt "run-main DPD.ScalaREPL dsm/simpleObserverPattern.dsm"
• To run unit tests: sbt test

Todo

Real todo

• Inspect vetted design pattern implementations (jhotdraw, java-design-patterns, head-first, gof)
• Create rules for as many patterns as possible
• Add discriminatory rules to the patterns to reduce false positives
• Add print pocket method that prints the list in pockets
• Add the IgnoreTest flag to ignore test classes in the patterns
• Implement scoring system
• Install understandand
• Try the new patterns from p.c.

Fancy todo

• Add function dsm to the mix
• Use machine learning to detect observer pattern
• Generate dsm and func from source using Understand
• Parse source files for additional meta-data

optimizations

• string paddTo
• 0-range).indices instead of zipWithIndex
