Hi, I am trying to create a sequence diagram with imported entities. I have several questions on this subject below.
I am using section "25.11 Including files or URL [!include, !include_many, !include_once]" as a guide here.
I start the sequence diagram with:
@startuml
'https://plantuml.com/sequence-diagram
!include base/base_system_entities.puml!
The first question is about the format of the `!` after the import. The only form that (seems) to work is using a `!` alone. Without a `!` I get an error, with a `!0` I also get an error. That *seems* to be inconsistent with the language reference guide. What have I misunderstood please?
Given that I have an import that *seems* to work, in that it doesn't have a syntax error, I now need to test whether the import *is* working.
The sequence diagrams, though, anyway implicitly create participants when they are declared, such that:
Alice -> Bob: Authentication Request
Bob --> Alice: Authentication Response
Will create the participants Alice and Bob.
If I want to declare Alice and Bob in my base_system_entities.puml file instead, though, and include that base into the sequence diagram, how could I know whether the included entity was being used? To ask that question another way, how could I change the declarations in the base such that the change would be reflected in the sequence diagram, and so I would know that the include was working?
In other UML systems, a message in a sequence diagram could be constrained to be a method on a class. Such that, for example, adding a message in a sequence diagram could create the corresponding method on the class. Conversely, the sequence diagram editor might require that a message can only be a method defined on a class. Do/can either of these types of constraints, or similar, be applied with PlantUML?
Many thanks
Nathan
