Feature request: Support `nix flake` subcommands

[x10an14]

Especially nix flake check, out of the box =)

So that nix flake check --log-format internal-json -v |& nom --json can be just nom flake check =)

+1 for this. I'd love to have nom flake check

It‘s on the road map.

A quick workaround for this that I'm using, and which could be extended to other commands, is adding the below function to my .bashrc; I expect something similar would work in other shells.

nom () {
    if (( $# >= 2 )) && [[ "$1" = flake && "$2" = check ]]; then
        shift 2
        nix flake check --log-format internal-json -v "$@" |& command nom --json
    else
        command nom "$@"
    fi
}

If you add the above and restart your Bash shell, then running nom flake check will call nix flake check with appropriate arguments and pipe the output into the real nom, while running nom with any other arguments will call it normally.

It's a bit of a hack and it's not as good as first-class support for this function, but it does the job well enough for my purposes!

(In fact the version I'm actually using is in my bashrc.d's nom file, which relies on my bashwrap Bash function, since this sort of wrapping another command is a trick I pull often enough that I wanted a standard implementation…)

Thx so much!
