[Feature] Add `--silent` back

Describe the user story

IMO, this was an important feature, heavily requested for the original yarn. Not sure why it was taken out. Really useful for CI environments and a no-brainer for most CLI tools out there. As an example, this is how a fairly typical CI log would look for us, making it really hard to mentally parse and navigate.

As far as I could gather, --silent was added as a “hidden” flag for compatibility purposes - but doesn’t really do anything. This is bound to trip people up.

Describe the solution you’d like

yarn --silent should not print anything at all and return the appropriate status code.

Describe alternatives you’ve considered

Right now, we are adding a bunch of general exclusions in .yarnrc.yml as logFilters for each project. Maybe those could be exposed as CLI flags?

[nfantone]

Agree with @davwheat here. Environments such as Docker and CI/CD were the main use cases for the addition of --silent in v1.

@arcanis I’ve been thinking about this:

The --silent flag was a blanket flag that couldn’t be controlled;

Isn’t that the exact reason why it was useful in the first place? When applying this kind of logging control flags, like --quiet, --verbose or --silent, having a dedicated, aptly named option for quickly altering the output is the right way to think about them. Giving users finer controls on that is great, but it should not come at the detriment of what is arguably the most common scenario you’d want to apply those controls in, anyway.

[nfantone]

Yeah - I’m aware of what the logs are saying. Thanks for pointing that out, but this is not what this issue is about, really.

Like I mentioned before, the pattern: * solution doesn’t work (requires at least one character that is not a wildcard). And also yarn config set logFilters --json '[{"pattern": "*", "level": "discard"}]' seems awfully verbose and awkward when all we’d like is --silent.
