Hello,
some years ago I inspired to add the timing diagram. Meanwhile I used it a lot but I'm missing a feature since not all actions are time dependent but event driven. So it would be nice to give some text instead of a timestamp. To make drawing easier it could be a good idea to always give a timestamp but to give an optional text that should be printed instead.
Here a possible example for the language extension:
@startuml
robust "DNS Resolver" as DNS
robust "Web Browser" as WB
concise "Web User" as WU
@0
WU is Idle
WB is Idle
DNS is Idle
@+100 is "URL given"
WU -> WB : URL
WU is Waiting
WB is Processing
@+200 is "URL request"
WB is Waiting
WB -> DNS@+50 : Resolve URL
@+100 is "DNS processing started"
DNS is Processing
@+300
DNS is Idle
@enduml
And here what it should look like:
What do you think?
