Activation shorthand for sequence diagrams

asked Aug 12, 2016 in Wanted features by onovotny (120 points)
It would be very convenient to have a shorthand notation for activation/deactivation with sequence diagrams instead of having to have a seperate line for 'activate' and 'deactivate'

The syntax I've seen with other text sequence diagram tools is to have a +/- on the end of the arrow:


Alice ->+ Bob: Hi (with activation)

Bob -->- Alice: How are you (deactivate)


Is there any chance for this? Thanks!

Thanks for the suggestion.

Note that we have a similar feature (see )

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

Is this what you are looking for ?

Hello plantuml,

this is a great feature.

Unfortunately, it doesn`t seem to be possible, to combine deactivation of source and activation of target. (Suggestion "-+" as indicator or please tell me how it is supposed to work if it already does.)

Thanks for the great work.
