Team

there is a library I load in a parallel execution process that prints something into REPL once succesfully loaded.

The problem is that when I run 100 parallel process I get a pretty much unusable REPL.

Is there a way to deactivate printing into the REPL and then activate it back?

Thanks

Maybe. Are we talking about a Julia library or an external C library? It would be better to file an issue with the library — I don’t think this is good behavior by default for libraries. (Imagine if every library did this.)

I’d say: teach the library not to do it. Better that way, IMO.
