cabal run sends bluid info and "Up to date" to stdout, should send to stderr

[alpha-bit]

Describe the bug

On cabal run ... 2> /dev/null the build processed is sent to stdout, even when has already built it sends "Up to date" to stdout.

I use this to test a command line program, i need to be able to use the output of the program.

To Reproduce
try cabal run ... 2> /dev/null

Expected behavior
Expected to all output from cabal run to go to stderr.

System information

• nix-shell @ Debian
• cabal-install version 3.6.2.0, ghc version 9.0.2

Would cabal run --verbose=0 my-program suit your workflow?

I am not sure sending stuff to stderr is the correct choice.

Thanks for the report! It's a dup of #7790, so I suggest we close.

@ffaf1 ::: Option --verbose 0 just works great, as needed... :)

( O.o ... i should have checked that. )

I am not sure sending stuff to stderr is the correct choice.

I do think everything not-data (for natural piping) should go to stderr.

[ty], Closing as suggested
