continue and break for loops in activity diagrams beta.

Question

Hello,

This has already been been proposed for activity diagrams in a previous year.

Implement break in repeat and while in activity diagrams

asked Aug 27, 2013 in Wanted features by anonymous

I suppose that it needs some considerable thinking and modifications of the activity diagrams beta. However, I think that it would be very beneficial when trying to simulate flowcharts of computer languages such as C++. It would render PlantUML even more comprehensive.

Other aspect to potentially consider are Switch-case statements, in C++ codes for example. Are there flowchart diagrams that PlantUML could not display?

Best regards,

Those have been implemented on recent versions.

How do you use continue in a repeat loop?

I have tried this:

@startuml
repeat
:action1;
if (is big?) then (yes)
:action55;
:action66;
continue
endif
:action2;
repeat while (is Big?)
@enduml

But the continue produces a syntax error.

I have looked at the source code and there is no string that looks up continue in the commands classes (the regex lookups). I dont know if we are meant to use goto? 

Is there another keyword to use?
