Passing --output /dev/stdout results in an error

[gridbugs]

Describe the bug

Passing /dev/stdout to --output gives the error:

bear: failed with: Events db open failed (file /dev/stdout.events.json): Permission denied

To Reproduce

$ bear --append --output /dev/stdout -- echo
bear: failed with: Events db open failed (file /dev/stdout.events.json): Permission denied

Expected behavior

I would expect setting the output to /dev/stdout would cause bear to write the compilation database to its standard output. Running the command above should print out an empty database ([]).

Environment:

• OS name: Linux
• OS version: NixOS (rolling, kernel is Linux 6.3.0)
• OS architecture: x86_64
• Bear version: 3.1.2
• Bear install method: Installed from nixpkgs using nix-shell

Hey @gridbugs , thanks for this report.

I think you are right, the tool should support IO redirects... Will work on this when I have free time.
