While condition in several lines

Question

In the activity diagram (beta), is it possible to allow the while condition in several lines?

In the if/else condition, it is possible to have several lines by adding a \n like this:

if( condition\n
on several lines) then (yes)

    :my activity;

endif

For the while, it could be the same:

while(condition\n
on several lines) is (yes)

    :my activity;

endwhile(no)

But actually, it generates an error.

Comments

I'm not sure if you realise that the "\n" in your 'if' example is not allowing you to run over multiple lines, it is actually adding an extra line feed into the text.

You could have alternatively written (note the blank line in place of the \n):

@startuml
if( condition

 on several lines) then (yes)
     :my activity;
 endif
@enduml

to achieve the same effect.

But I agree that it is inconsistent that 'if' text can run over multiple lines, but 'while' text can't.

(As pointed out below, you can use the single line "\n" notation instead.)

This is not very logical, but you can use:

Answer 2

Hello A.,

For more precision, in fact that generates on error only if that is on several line.

But if we use '\n' on one line that is good:

One-line: OK

@startuml
while (condition\non several lines) is (yes)
    :my activity;
endwhile (no)
@enduml

Multi-line: KO

@startuml
while (condition
on several lines) is (yes)
    :my activity;
endwhile (no)
@enduml

If that can help,

Regards,
Th.
