another way of activating and de activating in sequence diagrams

Question

Currently starting and stopping an activation takes two extra lines:

User->Task: start
activate Task
Task->Task : do something
Task->User: done
deactivate Task

I used to work with websequencediagrams that use a different syntax:

User->+Task: start
Task->Task : do something
Task->-User: done
 

This makes reading a bit longer sequence diagrams a lot easier.

Thanks for the suggestion.

Actually, you can use also this: http://plantuml.sourceforge.net/incubation.html

@startuml
alice -> bob ++ : hello
bob -> bob ++ : self call
bob -> bib ++  #005500 : hello
bob -> geoge ** : create
return done
return rc
bob -> geoge !! : delete
return success
@enduml

It indeed makes diagrams shorter.

Hope it helps!

Spectacular, plantuml! Thank you! Looking forward to seeing it in production!

Actually, it is in production. It's just not very well documented.
