Summary0003372: Diagnostics messages are written to stdout (instead of stderr)
DescriptionDoomseeker's startup logs (etc) are like diagnostics messages, but treated as normal output from the program. This goes against POSIX' description of stderr:

Quote
At program start-up, three streams shall be predefined: [...] standard output (for writing conventional output), and standard error (for writing diagnostic output).


stdout makes sense for --version-json as conventional JSON output, but the diagnostics messages should really be changed from stdout to stderr.
Steps To ReproduceOn Unix-like machines:

doomseeker 1>/tmp/stdout.log 2>/tmp/stderr.log


See /tmp/stdout.log and /tmp/stderr.log for messages of the appropriate standard stream.

This was fixed:https://bitbucket.org/Doomseeker/doomseeker/commits/87122ce09493fbad5fe718acf64ef2950167fd13 [^]

I thought of submitting a bug for the bug tracker for future reference, anyway.

Interestingly enough, I would like to reopen this issue for more discussion.

One of the answers in the linked Unix & Linux Stack Exchange thread argues whether POSIX-like programs should be quiet by default (that's an Unix-y thing to do), and only output to stderr if the exit status was non-zero. To quote:

Quote from POSIX.1-2008, 1.4 Utility Description Defaults
Default Behavior: When this section is listed as "The standard error shall be used only for diagnostic messages.", it means that, unless otherwise stated, the diagnostic messages shall be sent to the standard error only when the exit status indicates that an error occurred and the utility is used as described by this volume of POSIX.1-2008.


Do we need to introduce a command line flag for --quiet or --verbose? I'd keep them to stderr, though.

Haha disregard that, stdout probably makes more sense with a --verbose (or -v) flag with quiet by default behavior. Anyone agree?

stderr for real diagnostics errors, though.

--version-json could indeed benefit from not being spammed with stderr logs by default
