Reference participants using aliases in procedures

Question

Using the legacy !define allowed you to use aliases in macros. How do you do this with !procedure and !function?

Working:

Comments

I was able to do this by encapsulating the aliases in double quotes, like this:

Is this the intended way of using it?

Answer 1

The 2 defined types for arguments are int and string. So add "alice" and it is working well:

or use !unquoted procedure

Answer 2

Hello L.,

With !procedure or !function, we must use double or simple quote for arguments.

@startuml
!procedure note_over($target, $note)
  note over $target: $note
!endprocedure

participant "Alice" as alice
note_over("alice", "some note")
@enduml

Or explicitly mention '!unquoted':

@startuml
!unquoted procedure note_over($target, $note)
  note over $target: $note
!endprocedure

participant "Alice" as alice
note_over(alice, "some note")
note_over(alice, other note)
@enduml

If that can help,
