Defined in:

Overview

This class parses a command name out of the yard CLI command and calls that command in the form:

$ yard command_name [options]

If no command or arguments are specified, or if the arguments immediately begin with a --opt (not --help), the CommandParser.default_command will be used (which itself defaults to :doc).

Adding a Command

To add a custom command via plugin, create a mapping in CommandParser.commands from the Symbolic command name to the Command class that implements the command. To implement a command, see the documentation for the Command class.
