[Activity][Style] Allow full style on diamond (e.g. internal label and external label)

Question

Hello PlantUML team,

• Could you allow full style on diamond (e.g. internal label and external label), on Activity Diagram?

Question:

• What is the stylename (SName) for the external diamond label?

Here are some examples:

1/ With Simple Conditional:

@startuml
<style>
activityDiagram {
  MaximumWidth 100
  diamond {
    FontColor green
  }
}
</style>
if (Long long long long long long long long long condition?) then (Long long long long long long long long long yes)
  :Long long long long long long long long long action yes;
else (Long long long long long long long long long no)
  :Long long long long long long long long long action no;
endif
@enduml

→ `MaximumWidth 100` seems to not take in account for internal diamond label and external diamond label

2/ With switch/cases

@startuml

<style>
activityDiagram {
  MaximumWidth 100
  diamond {
    FontColor green
  }
}
</style>
switch (Long long long long condition? )
case ( Long long long long long long long long long case 1)
   :Long long long long long long long long long  1;
case ( Long long long long long long long long long case 2 )
   :Long long long long long long long long long  2;
endswitch
@enduml

→ `MaximumWidth 100` seems to be ignored  for internal diamond label and external diamond label
And also the color `FontColor green` is not taken in account.

Regards.

In last release V1.2021.12 we have improved support for style and diamond in activity diagram beta.

However, we are interested if you find other issues concerning this topic.

Thanks for your tests!

Hello PlantUML,

Thanks for the improvement... Then...

• Could you add some margin or padding between arrow and label?

See little overlapping:

@startuml
scale 2
<style>
activityDiagram {
  MaximumWidth 100
}
</style>
switch (Long long long long condition?)
case (Long long long long long long long long long case 1)
   :Action  1;
case (Long long long long long long long long long case 2)
   :Action  2;
endswitch
@enduml

Another remark, with Simple Conditional, we observed always the defect...

@startuml
<style>
activityDiagram {
  MaximumWidth 100
  diamond {
    FontColor red
    MaximumWidth 100
  }
}
</style>
if (Long long long long long long long long long condition?) then (Long long long long long long long long long yes)
  :Action yes;
else (Long long long long long long long long long no)
  :Action no;
endif

Thanks for your works...
Another remark (sorry ):

• Could PlantUML manage also 'elseif' Conditional, here is the test...

@startuml
<style>
activityDiagram {
  MaximumWidth 100
  diamond {
    FontColor red
    MaximumWidth 100
  }
}
</style>
start
if (Long long long long long long long long long condition?) then (Long long long long long long long long long yes)
  :Action yes;
elseif (Long long long long long long long long long another condition?)
->Long long long long long long long long long elseif;
  :Action elseif;
else (Long long long long long long long long long no)
  :Action no;
endif
@enduml

Regards.

Another remarks: 

• See little overlapping (on red), observed on even switch-case label:

@startuml
scale 1.5
<style>
activityDiagram {
  MaximumWidth 100
  diamond {
    FontColor green
  }
}
</style>
switch (Long long long long condition? )
case (Long long long long long long long long long case 1)
   :Long long long long long long long long long  1;
case (<b><color:red>Long long long\nlong long long long long long case 2)
   :Long long long long long long long long long  2;
case (Long long long long long long long long long case 3)
   :Long long long long long long long long long  3;
case (Long long long long long long long long long case 4)
   :Long long long long long long long long long  4;
endswitch

Hello PlantUML team,

Here is old example, with overlapping of arrow:

@startuml
switch (Long long long Long long <b><color:red>long condition?)
case (Long long long long long long long long long case 1)
   :Action  1;
case (<b><color:red>Arrow Error\nLong long long long long long long long long case 2)
   :Action  2;
endswitch

This case seems fixed.
