Make swift-format default behavior friendlier when passed no arguments

[janniksam]

Environment:

• WSL2 Ubuntu 20.04
• Swift 6.0.2

I saw #861 and created a .swift-format file in the project dir (also tried on layer above), but I'm still having issues with a hanging swift-format.

is there a way to enable verbose diagnostics for swift-format or is there any other method to find out, where its getting stuck?
Do I maybe just have to wait for 6.0.3?

Running swift-format without any arguments will wait for input from stdin. You need to pass a few flags to have it format files in place. What you might want is something like swift-format -r -i ..

There's some good discussion about the default behavior being less-than-intuitive here: https://forums.swift.org/t/default-behavior-of-swift-format/74314. It's something we'd like to improve in the future.

Thank you, working like a charm when you do it right. I feel dumb now. :)

You shouldn't! It's good signal that we can do more to smooth out the on-boarding process.

I'll go ahead and close this since it's resolved.

Let’s keep this issue open to consider a potential default behavior change of swift-format without any arguments.

That's fine. I've updated the title to better reflect what we want to do.
