I'm not too fond of it, and IDE2 does not need it.

On the IDE2 side, the gRPC log files preference should be a path to a folder. IDE2 should create a new log file per app session.

I've never seen an app/tool updating log files by erasing the content from the previous session.

@kittaakos it depends on what we want to achieve on the IDE. I believe a single file being overwritten every time is enough because otherwise, the CLI would log tons of lines and as a user, I wouldn't want to find a folder with a 10GB log file.

But this is only my opinion. In any case, with the change made in this PR we can still achieve what you are saying (that is: having a log file per session), we'd just need to name every file differently.

Let's discuss this in a separate thread because whether or not we'll have multiple log files in the IDE, it's not a CLI matter.

I wouldn't want to find a folder with a 10GB log file.

Then don't enable it.
