No way to wait for non-blocking logging

[deadmoose]

It's (somewhat) not a problem for a long-lived things, but the checked-in example demonstrates it:

• It logs a message, this fires off a goroutine to post to slack
• End of main() is reached & the program terminates

The goroutine never gets a chance to do anything, so nothing makes it to slack.

Tossing a time.Sleep() in obviously let me prove the handler does work when given the opportunity to, but I don't have any brilliant suggestions around a more general solution.

I made it async because blocking the main thread for logging seems dangerous.

We can either add a defer slogslack.Close() or a async handler option. Do you have any other idea ?

I'm running into the same problem. I would add a Sync method like zap logger does.
