As a follow-up, the design document on static name remapping will need an update as well. |

So this is back :D. We should figure out what we're doing here and be consistent. Unless I missed it this wasn't a constraint mentioned above. I think we may have wanted to keep it to allow us to have a "safe" delimiter to use in the future, but it looks like the code doesn't check this, at least for topics.

Made this constraint explicit everywhere else in 7680627. Do you think we shouldn't?

Hmm, not sure. I think we only needed it for the alternative we're no longer using. I don't think the code enforces it at the moment. Maybe it should be removed. @sloretz or anyone on the @ros2/team do you have an opinion here?

I don't have a strong preference. But it seems okay to remove the constraint if there's no reason to have it. If we really need it in the future, we could start using repeated . as a delimiter since it's already disallowed.

@hidmic What is the status on this? Can it be merged or does it need to move forward to the Foxy board? |
|
It has yet to be implemented, so if anything it has to go to the Foxy board. It was brought up during our brainstorming for Foxy, but AFAIK it has a rather low priority. |
