Can \n, \t, etc. be handled within note texts?

Question

For ex

!define NOTE_TEXT Note:\nnew line text\n\tnew line tabulated text

note right

NOTE_TEXT

end note

Hi! Are there any suggestions on this?

Answer 1

When a note is defined on several lines (like your example), \n is not interpreted as carriage return.

When a note is defined on a single line (like in the following example), \n is interpreted as carriage return

@startuml
!define NOTE_TEXT Note:\nnew line text\n\tnew line tabulated text
note right: NOTE_TEXT
@enduml

Does it help you ?

Hi!
Thank you. However, I want to have an ability to indicate \n by passing an argument to the note while the note itself is already multiline

!definelong explain(arg)
   note right
      The explanation is:
      arg
   end note
!enddefinelong

explain(Explanation line 1\nExplanation line 2)

A workaround could be to have:

!definelong explain(arg)
note right: \nThe explanation is:\n<U+FEFF>arg
!enddefinelong

We have to use a ZERO WIDTH NO-BREAK SPACE U+FEFF to separate \n and arg. This solution is really ugly, but maybe it will work for you ?

Ok. Will try. Thank you!
Is there a way to ignore \n in the arg (that is, display nothing where the "\n" is) when rendering note?
