posewithcovariance array? #110

Closed protobits closed 6 years ago

protobits commented 7 years ago

Would it be possible to add an array message definition for PoseWithCovariance? This would be useful to publish history of poses with covariance in a single message, which is not currently possible.

Generally I'd rather not just add an Array datatype. There are a few left over that are kept around for backwards compatibility. A container with an array takes the same number of lines to define as using the array synatax and doesn't improve sematnic meaning.

It sounds like you have a specific use case with semantic meaning. I'd recommend making a custom msg with exactly what you want and a sematically meaningful name as well as possibly some other relevant metadata that would be relevant to making the contents of the message self contained.
