Suppress numbering in selected messages in a sequence diagram

Question

Hi,

just came across PlantUML and like it very much.

I have a use case for which I did not find in the documentation how to solve it: When autonumber is switched on, I need to suppress numbering for selected messages.

Is there a command / syntax for it?

If there isn't, would it be possible to add it as a new feature?

Thanks Uwe

I too am after this.
Telling plantuml to discard this message/interaction, w r t autonumbering.

Related possibilities: 

• Using the %autonumber% feature could work but does , since there is no way to store it in a variable.
  See https://forum.plantuml.net/11918/use-an-autonumber-reference-in-another-location
• Another idea was:

Actually, this is possible but the syntax is not super-concise.

For each signal/message that you want to not have autonumbered, you need to surround it in autonumber stop / autonumber resume. Like so:

@startuml
autonumber
a -> b: hi
autonumber stop
b -> c: extra
autonumber resume
b -->> a: hello

This is not possible to do so, but we will think about adding this new feature.

Thanks for the suggestion,

Hi from 2021. This is possible now. Using autonumber stop / autonumber resume

Adding this to clarify, repeating my comment from above:

Possible but the syntax is not super-concise: For each signal/message that you want to not have autonumbered, you need to surround it in autonumber stop / autonumber resume:

@startuml
autonumber
a -> b: hi
autonumber stop
b -> c: extra
autonumber resume
b -->> a: hello
@enduml
