cmd/netwatch-server/main.go parsed the command line, ran the check-cidr and prepare-data-dir subcommands and built the fx application itself; the Go style guide puts all of that in internal/ or pkg/. The new package internal/cli does it, with the same arguments, messages and exit codes. main() is now os.Exit(cli.Main(os.Stderr, Appname, Version, os.Args[1:], cli.RunServer)): Main takes the writer for errors and the function that runs the server, so its tests give it a buffer and a function that fails them. Appname and Version stay in main, where the build sets Version. The function behind prepare-data-dir also takes the volume and the user's name, so its own tests give it a temporary directory and the user they run as. Model: opus-5-5
