Partitions (group of actions) in Activity Diagram Beta

Question

Hello,

I would like to have partitions that could represent groups of actions, or "activities".

Example:

partition ":go up the stairs;" {

 :go up first step;
 :go up second step;
 if (tired) then(yes)
   :stop a bit;
 endif
 :go up last steps
}

The idea of partition (which I want to distinguish from swimlane), is included in the old syntax of activity diagrams.

Is it also currently present in the syntax of activity diagrams BETA? Otherwise I'd like to ask that it be implemented.

Note: this "partition" feature could be used as well to embed the whole activity inside a partition frame, and not just a subgroup of actions.

Answer 1

Wow this is great!

One issue is that partitions are not independant

 

partition ":go up the stairs;" {

 

 :go up first step;

 :go up second step;

 if (tired) then(yes)

   :stop a bit;

 endif

 :go up last steps

}

 

partition ":go up the stairs;" {

 

 :go up first step;

 :go up second step;

 if (tired) then(yes)

   :stop a bit;

 endif

 :go up last steps

}

Actually, there is missing ";" on the ":go up last steps", which cause this strange & unexpected behaviour...

Corrected version:

@startuml
partition ":go up the stairs;" {

 :go up first step;
 :go up second step;
 if (tired) then(yes)
   :stop a bit;
 endif
 :go up last steps;
}


partition ":go up the stairs;" {

 :go up first step;
 :go up second step;
 if (tired) then(yes)
   :stop a bit;
 endif
 :go up last steps;
}

Nice. Thank you. Partitions work great.

Thanks!, still there's an arrow between both partitions. If it was possible to trigger the isKilled() method by using a special notation this would solve the problem

For example:
@startuml
partition ":go up the stairs;" {

 :go up first step;
 :go up second step;
 if (tired) then(yes)
   :stop a bit;
 endif
 :go up last steps)
}


partition ":go up the stairs;" {

 :go up first step;
 :go up second step;
 if (tired) then(yes)
   :stop a bit;
 endif
 :go up last steps)
}

Notice the ")" instead of ";" in " :go up last steps)". I've already hacked it, but I can't modify the activitycommand regex. My mental regex parser needs more training :)

Yes, some regex have been generated by random, and once they are working, we do not modify them any more :-)

Speaking about arrows, there is a working feature that we are going to document soon (this is already working):
@startuml
:foo1;
-> You can put text on arrows;
if (test) then
  -[#blue]->
  :foo2;
  -[#green]-> The text can
  also be on several lines
  and **very** long...;
  :foo3;
else
  -[#black]->
  :foo4;
endif
-[#gray]->
:foo5;

Rather than using ")" [this begins to be too cryptic somehow], we are thinking about extending the -[#color]-> notation to something like:

:foo1;
nolink
:foo2;

In this case "nolink" would mean that there are no arrow between foo1 and foo2.
What do you think about it ?

Sounds great!

Will it also be possible to position partitions? Something like top, left, right, or bottom?

Let me know if I can help.
