Could I display the transitions names in the PlantUML state-machine chart ?

My ThingML code

       statechart ChatBot init start_conversation {

             state start_conversation {
                    transition -> start_new_topic
             }

             state start_new_topic{
                    transition should_start_small_talk -> small_talk
                    transition should_ask_for_category -> ask_for_category
                    transition user_wants_to_leave_conversation -> goodbye
             }

             state small_talk{
                    transition should_continue_small_talk -> small_talk
                    transition should_ask_for_category -> ask_for_category
                    transition should_continue_ingoing_conversation -> talk_about_topic
             }

             state ask_for_category{
                    transition vague_category -> start_new_topic
                    transition has_identified_category_correctly -> talk_about_topic
             }

             state talk_about_topic{
                    transition should_continue_conversation -> talk_about_topic
                    transition shouldnot_continue_conversation -> start_new_topic
                    transition user_wants_small_talk -> small_talk
                    transition user_wants_to_leave_conversation -> goodbye
             }

             state goodbye{}     
       }

Yes, should be quite easy...

[brice-morin]

which version of ThingML are you using? The one based on EMFText, or the one based on XText (ThingML v2)?

[fungiboletus]

EMFText because I followed the documentation, but I will compile the XText version very soon. So assume it's XText.

[brice-morin]

OK, should be fixed in XText branch

Some wild \n appeared.

But when I removed them, I got something strange. I guess something is messing between the next state and the transition's name.

[brice-morin]

Hmmmm, those \n, \\n, etc is quite a pain in plantUML :-) But I will try to fix that

[brice-morin]

this time, it should work :-)
