Question

How to add a snippet of code inside a state in a statechart?

Answer 1

Hi M., and all,

Here is a proposal, according that state allows only mono-lines:

@startuml

[*] --> State1
State1 --> [*]
State1 : this is a string
State1 : adding **some code**:\n\
main() {\n\
  printf("Hello world");\n\
}

State1 -> State2
State2 --> [*]

• https://forum.plantuml.net/13071/newline-in-state-diagrams-is-inconsistent

@PlantUML: similar to:

• https://forum.plantuml.net/13945/extend-wbs-syntax-to-allow-multiline-nodes

Here is a wanted feature:

• Extend State syntax to allow multiline state

With this proposal:

@startuml

[*] --> State1
State1 --> [*]
State1 : this is a string
this is another string on multi-line;

State1 -> State2
State2 --> [*]

If that make sense...

If that can help,
Regards.
