Regardless of whether your command is called with named parameters, positional parameters or boolean flags, you'll access them the same way: via the standard CFML arguments scope. The user will be prompted for required parameters if they haven't provided them, and the defaults you configured will also work just like you expect.

If the parameters were escaped when typed into the command line, you will receive the final unescaped version in your command.

Dynamic Parameters

Users can pass named or positional parameters that aren't declared, and they will come through the arguments scope. Named parameters will be accessable as arguments.name, and positional parameters as arguments[ 1 ], arguments.[ 2 ], etc.

This can allow for powerful commands like package set that allows users to set any box.json property they want.

package set foo=bar

File System Paths As Parameters

If your command accepts a file or folder path from the user, you'll want to resolve that path before you use it. To do this, use the resolvePath() method that is available to all commands via the BaseCommand class. (This method wraps the resolvePath() method of the fileSystemUtil object that is injected into all commands.) The method resolvePath() will make the file system path canonical and absolute. This ensures you have a fully qualified path to work with even if a user might passed a folder relative to their current working directory passed something like ../../.

component extends="commandbox.system.BaseCommand" {
​
    function run( String directory )  {
        // This will make each directory canonical and absolute
        arguments.directory = resolvePath( arguments.directory );
        return arguments.directory;
    }
}

If you run that command and pass a full file path such as C:\sandbox\testSite, you would get that exact same path back as the output.

However, if you changed the interactive shell to the C:\sandbox directory and then ran the command with testsite as the input, the relative path would now still resolve to C:\sandbox\testSite.

If, from the same directory, you passed testsite/foo/bar/../../, you would still get C:\sandbox\testSite as the path.
