CLI: Only print changed files

[nex3]

Right now, when running the formatter from the command-line on a large package, it prints a line for each file it looks at, whether or not that file was changed. This produces a lot of noise for very little information, and makes it very hard to see which files actually did change—or worse, whether a file had a syntax error. It would be much easier to understand if it only printed files that were reformatted or failed to parse.

Yeah, I'd like to do this too.

Similar to #715

Maybe -q for "only changed files" and -qq for "completely silent"?

Is this issue fixed?

Yes, the new CLI you get using dart format (as opposed to dartfmt) only prints changed files by default.

Is there a way to access that CLI for a specific version of the formatter? In Dart Sass, we run the formatter both from the CLI and from dart_style's Dart API, and we need to make sure we're using the same version of each of these so we get the same formatting.

No, the new CLI isn't directly exposed by dart_style, only through dart format. It wouldn't be too much trouble to add another entrypoint to do that, but I was trying to avoid increasing the surface area I need to support so didn't. So that means you always get whatever version of dart_style was bundled with the version of the Dart SDK you run dart format from.

I'm guessing you used pub run to run it? If you want to run the formatter from a dependency on dart_style, you're probably better off still using the old CLI, which is still supported.
