[State Diagram] junction pseudo-states

asked Dec 27, 2023 in Wanted features by Esperito (140 points)
In state diagrams, the choice pseudo-state is supported, but the junction pseudo-state is not supported.

By non-support of the junction pseudo-state, I could not design  state machine that is slightly complicated without increasing states or transition.

I want to append the 'junction' stereotype.
I know that the 'start' stereotype is simlular to the junction pseudo-state.
By using the 'start' stereotype,  the PlantUML generates the start pseudo-state symbol that is same appearance to the junction pseudo-state symbol.
I think that it is easy to support the 'junction' stereotype.

Please try to be constructive when considering this matter.

How about  this (use entryPoint in an invisible state as junction point)


state choice1 <<choice>>

state " " as X #white;line:white {

state " " as junction1 <<entryPoint>>


[*] --> Idle

Idle --> choice1 : CoffeeRequested

choice1 --> BeansGrinding : [isUngrindedBeans?]

choice1 --> junction1 : [else]

BeansGrinding --> junction1

junction1 --> BeansFilling : / UpdateRecipe()
