  • Heroku CLI sub-commands
    • E.g: heroku domains:add www.myapp.com

    • Colons are preferable to help delineate the command between the arguments passed to the command. The user quickly learns that argument 1 is the command and how to get help for it.
      
      Getting into the weeds a little bit, there is another technical reason why we prefer colons. For topic-level commands like $ heroku domains we list all the domains of an app. If we used spaces to separate commands from subcommands and wanted this topic-level command to accept an argument, the parser could have no way to determine if the argument was a subcommand or argument to the topic command. Therefore, using spaces to separate makes it so you cannot have topic-commands also accept an argument.
