How can I exclude child-nodes from instantiation?

[sanyakamra]

Hello @erikbosch
I am trying to exclude few child node. And I tried

Cabin.vspec

Door:
type: branch
instances:
- Row[1,2]
- ["DriverSide","PassengerSide"]
description: All doors, including windows and switches
#include SingleDoor.vspec Door

Door.SomeSignal:
datatype: uint8
type: attribute
instantiate: false
description: A door signal that should not be instantiated.
But this is still not excluding the child node. Can you please guide in it if I am missing anything else?
Thanks!
VSS_TOOLS_VERSION = 4.1

It depends a bit on what you want to do. The instantiate: false keyword is intended to exclude a signal from instantiation. Taking IsChildLockActive as example. If you (in a fork or in an overlay) specify instantiate: false you will get one signal entry as result:

erik@debian6:~/vehicle_signal_specification$ egrep -ni ischildlock *.csv
580:"Vehicle.Cabin.Door.IsChildLockActive","sensor","boolean","","","","","Is door child lock active. True = Door cannot be opened from inside. False = Door can be opened from inside.","","",""

... rather than 4 ...

erik@debian6:~/vehicle_signal_specification$ egrep -ni ischildlock *.csv
590:"Vehicle.Cabin.Door.Row1.DriverSide.IsChildLockActive","sensor","boolean","","","","","Is door child lock active. True = Door cannot be opened from inside. False = Door can be opened from inside.","","",""
604:"Vehicle.Cabin.Door.Row1.PassengerSide.IsChildLockActive","sensor","boolean","","","","","Is door child lock active. True = Door cannot be opened from inside. False = Door can be opened from inside.","","",""
619:"Vehicle.Cabin.Door.Row2.DriverSide.IsChildLockActive","sensor","boolean","","","","","Is door child lock active. True = Door cannot be opened from inside. False = Door can be opened from inside.","","",""
633:"Vehicle.Cabin.Door.Row2.PassengerSide.IsChildLockActive","sensor","boolean","","","","","Is door child lock active. True = Door cannot be opened from inside. False = Door can be opened from inside.","","",""

VSS-tools 4.2 introduced the ability to delete nodes. It was not well documented in VSS documentation, so I added some more documentation in #763

That can be used to delete a single instance/signal combination like this:

Vehicle.Cabin.Door.Row2.DriverSide.IsChildLockActive:
  datatype: boolean
  type: sensor
  delete: true

or deleting all instances of it:

Vehicle.Cabin.Door.IsChildLockActive:
  delete: true
