Node link placement differ between simple and composite Node

Question

Hello,

I use plantuml.8033.jar

 

The link direction between a single node and a node with a component are different (D1)

I am happy with the sample on first page, but not on second one.

 

@startuml

node  "P1" as P1{

[P2] as P2

}

node  "switch" as switch

switch -- P2 

 

node  "C1" as C2 {

[C3] as C3

}

C3 -- switch

 

node  "D1" as D1 {

'REMOVE THIS COMMENT [D2] as D2

}

switch - D1

newpage

node  "P1" as P1{

[P2] as P2

}

node  "switch" as switch

switch -- P2 

 

node  "C1" as C2 {

[C3] as C3

}

C3 -- switch

 

node  "D1" as D1 {

[D2] as D2

}

switch -right- D1

Could you please help me?

 

Thanks for this great software

 

Answer 1

The is an undocumented feature that will help you.

You can add a special command to enable this:
!pragma horizontalLineBetweenDifferentPackageAllowed

The reason why it's disabled by default is that Graphviz is sometimes crashing with this feature.
BTW, tell us if you find some crashes.

Example:

 

@startuml
!pragma horizontalLineBetweenDifferentPackageAllowed
node  "P1" as P1{
[P2] as P2
}
node  "switch" as switch
switch -- P2
 
node  "C1" as C2 {
[C3] as C3
}
C3 -- switch
 
node  "D1" as D1 {
[D2] as D2
}
switch -right- D1
