This repository aims to implement the formalization, automatic generation, and rendering of UML state diagrams.

It currently contains the following functionalities:

• Under the folder alloy, it provides the formalization of UML state diagrams in Alloy. User can run uml_state_diagram.als to generate different Alloy sd instances and play around.
• Under the folder app, it provides the following executables:
  • draw.hs: draws Alloy sd instances via Haskell diagrams library.
  • drawing.hs: draws Haskell sd instances via diagrams library.
  • enumeratedArrowsDirectDemo.hs: generates a demo of sd "flatten" tasks, but currently not supporting concurrent states and history nodes.
  • enumeratedArrowsQuizDemo.hs: a quiz task corresponding to the "flatten" demo.
  • sampling.hs: generates random Haskell sd instances and draws them via diagrams library.
  • transformAlloy.hs: transforms Haskell sd instances into Alloy code that describes exactly those instances.
  • transformPlantUML.hs: transforms Haskell sd instances into plantUML code and then renders them. There are some constraints that can be found in plantUML/document.txt and issue 25.

• Alloy Analyzer
• Haskell GHC & Stack
• Java JDK/JRE (> 8)
• Graphviz
• PlantUML
