Feature Request: loglevel output control

[jasonkarns]

I would like to silence the output of non-modified files.

I first tried silencing STDOUT, but that also silenced the output of files that are modified. (Would be nice if these were on different streams.)

Then, acknowledging that prettier-standard uses prettierx under the hood, I started throwing prettier's CLI flags. --loglevel warn|silent|error etc.

Then I just started guessing with --silent, --quiet, -q, etc.

Ideally what I'd like is for the output of non modified files to go to a different stream than the names of files that are modified. I don't have strong opinions on which goes where. On one hand, printing files that aren't modified on STDERR could make sense (that would be considered diagnostic output since prettier-standard's primary purpose is to format files). OTOH, files that need modifying are/were in an "error" state prior the invocation.

A stretch goal would be to accept the same CLI flags as prettier for the loglevel. That would allow more fine grained control. Again, I don't have a strong opinion on what levels apply to what. As long as I can quiet the output to only print modified files.
