Format to stdout

[DamienCassou]

Some general-purpose formatting tools prefer language-specific formatting tools to write to stdout:

By default, reformatter.el expects programs to read from stdin and write to stdout, and you should prefer this mode of operation where possible

Would it be possible for nixfmt to have a mode of operation writing to stdout?

On my phone right now so I can't test, but I'm pretty sure that works by default!

@infinisil I think only when formatting stdin, not when formatting a file on disk. Not sure if that's what's needed here though since the quote above expects that exact behavior

I think only when formatting stdin

this is good enough for me. Thank you. Maybe the --help could mention that?
