Accept hexagon with smetana [Deployment diagram]

Hello PlantUML,

- Now: combinatorial is more and more -

  • Could you accept hexagon element with smetana (the internal Java port of GraphViz/Dot embedded in PlantUML sources)?

Here is the result of the test:

elementnodehexagon
code
@startuml
!pragma graphviz_dot smetana
node h [
more
and
more
combinatorial
]
@enduml
@startuml
!pragma graphviz_dot smetana
hexagon h [
more
and
more
combinatorial
]
@enduml
output
resultOK with nodeKO (NullPointerException) with hexagon

Thanks for your support,
Regards,
Th.

Hello PlantUML,

Idem (NullPointerException) with:

!pragma layout smetana

Hello PlantUML team,

  • Could you have a look on this 'NullPointerException'?

For the theme gallery, I wanted to use 'smetana' to avoid installing GraphViz, but I keep getting this error... (in the diagrams that contains a hexagon...)

Thanks for yours works,
Th.

I had a quick look but do not understand that part of the code enough.

This one is hard to fix, because it has an impact on the portage C-to-Java of graphviz library (portage which is not finished...)

A first and quick fix could to be to simply ignore the hexagon (and draw a rectangle instead).

Ok, no problem...

In C4-Stdlib a rectangle based "octagon" (via skinparam DiagonalCorner 18)  is used instead of the hexagon (I think it has the better text layout at all).

@startuml
skinparam DiagonalCorner 18
!pragma layout smetana
rectangle h [
more
and
more
combinatorial
]
@enduml

Thats very nice yes

commented Nov 2, 2021 by The-Lu (46,280 points)

Thanks a lot @Kirchsth,

But DiagonalCorner also affects agent...wink

@startuml
skinparam DiagonalCorner 18
!pragma layout smetana

agent agent
rectangle rectangle
@enduml

Then:

  • either I install Graphviz,
  • either I wait for the correction in Smetana...
    and in the meantime I do not use the hexagon.

Ok, no problem...

OK, my description was too short wink

@startuml
!pragma layout smetana

skinparam rectangle<<octagon>> {
    DiagonalCorner 18
}

agent agent
rectangle rectangle
rectangle service <<octagon>>
@enduml

Ah! OK. Thank a lot. yes

But with style and new [beta] style, I no longer use skinparam and I forgot all about skinparam...

Regards.
