Free tool to generate all paths from a diagram

Question

Good afternoon everyone,

Dispite a lot of research on the web I didn't found a solution that meets my need.

I need to find a free tool to modelize process (like BPMN, UML activity diagram) and generate all possible paths/combinations from the diagram.

Do you have any idea what tool can help me do that? Thank you a lot.

I am not sure that such tool on the shell exists. My advise would be to choose one modelling tool which

1. supports your modelisation (BPMN, Activity, etc.),
2. can be extended with a language you are confortable with (Python, Java, C#, etc.).

In this case, you will find several tools for sure. For fun, I picked Modelio (https://www.modelio.org/), made a small activity example, and a Jython script for it.

## return first initial node in the selected activity
def getInitialPoint(act):
   for  node in act.getOwnedNode():
      if isinstance(node, InitialNode):
         return node

## parcours activity nodes
def getPaths(currentPath, currentNode): 
  for outgoing in currentNode.getOutgoing():
    node = outgoing.getTarget()
    if isinstance(node, ActivityFinalNode):
       paths.append(currentPath)
       return;
    elif  isinstance(node, DecisionMergeNode):
       getPaths(currentPath, node)  
    else:           
       getPaths(currentPath + " - "  + node.getName(), node) 

 ##Init
 init = getInitialPoint(elt)
 currentPath = init.getName()
 global paths
 paths = []
 getPaths(currentPath, init)

 ##Print founded paths
 for p in paths:
   print p 

Hoping it helps, EBR
