VisB

VisB is a plugin for ProB2-UI, the new user interface of ProB based on JavaFX and the ProB2-Java-API . It is included in the latest Snapshot Download#ProB2_UI_using_Java_FX builds of ProB2-UI, but can be downloaded at https://www3.hhu.de/stups/downloads/prob2/plugins/ for older version of ProB2-UI.

An article about VisB has been published in the ABZ'2020 proceedings.

Installing VisB Plugin

To install VisB in the JavaFX-based ProB2-UI you need to:

1. Choose "Plugin Menu" in the Advanced menu 2. Click on the "Add Plugin..." button. 3. Select the VisB JAR file you have downloaded from https://www3.hhu.de/stups/downloads/prob2/plugins/ 4. Choose the "Open VisB" command in the Advanced menu

You can now choose a JSON file which builds on top of a SVG graphics file. The JSON file contains a reference to a SVG file, along with entries to modify attributes based on the current state of a B model and entries which specify how VisB should react to clicks on the SVG. The SVG file should contain object ids which are referenced in the JSON file.

Here is a sample file:

{
  "svg":"Train2.svg",
  "items":[
    {
      "id":"Train1_rect",
      "attr":"visibility",
      "value":"IF 1:TRAIN THEN \"visible\" ELSE \"hidden\" END"
    },
    {
      "id":"Train1_rect",
      "attr":"fill",
      "value":"IF train_speed(1)>0 THEN \"blue\" ELSE \"orange\" END"
    },
    {
      "id":"Train1_rect",
      "attr":"x",
      "value":"train_back_loc(1)*10+20"
    },
    {
      "id":"Train1_rect",
      "attr":"width",
      "value":"train_length(1)*10"
    }
    ],
  "events":[
    {
      "id":"Train1_rect",
      "event":"Train_Move1",
      "predicates":[
        "1=1"
      ]
    }
    ]
}
