for free-function callbacks we've been capturing the logger in a callback and passing it to the handler: ros2/demos@52dbdac

I thought this was unnecessary complexity here for just passing a string around so I didnt do it on purpose.

Which string so you mean? If it's the logger name then the purpose is to have it reflect remapping on the node name (which isn't possible today but they'd be set up for when it's possible)

I meant the logger. I think that as it stands it doesnt deserve doubling the size of the main to propagate it. I integrated @wjwwood suggestion (#191) instead.

Yeah indeed that's important to leverage when this becomes available. I was just discussing this with wjwwood and we agreed that hopefully by then we will provide an easy way for user to pass additional argument to callbacks as logging from callback is something very common.
* possible simple solution to free function logging * typo

Segfaults since the global variable is never set.

Actually this example works fine. I think you're referring to the not composable subscriber. See #195 for a fix
I also changed the message printing from
Publishing: [%s]toPublishing: '%s'as[INFO] [publisher_node]: Publisher: [Hello, world! 0]was getting a bit full of[and harder to scope the user printed message.In Python it prints
Publishing: "%s"but I can change it if we want the messages to be identical in both languages
