NAME

       App::Cmd::Command - a base class for App::Cmd commands

VERSION

       version 0.323

METHODS

   prepare
         my ($cmd, $opt, $args) = $class->prepare($app, @args);

       This method is the primary way in which App::Cmd::Command objects are built.  Given the
       remaining command line arguments meant for the command, it returns the Command object,
       parsed options (as a hashref), and remaining arguments (as an arrayref).

       In the usage above, $app is the App::Cmd object that is invoking the command.

   new
       This returns a new instance of the command plugin.  Probably only "prepare" should use
       this.

   execute
         $command_plugin->execute(\%opt, \@args);

       This method does whatever it is the command should do!  It is passed a hash reference of
       the parsed command-line options and an array reference of left over arguments.

       If no "execute" method is defined, it will try to call "run" -- but it will warn about
       this behavior during testing, to remind you to fix the method name!

   app
       This method returns the App::Cmd object into which this command is plugged.

   usage
       This method returns the usage object for this command.  (See Getopt::Long::Descriptive).

   command_names
       This method returns a list of command names handled by this plugin. The first item
       returned is the 'canonical' name of the command.

       If this method is not overridden by an App::Cmd::Command subclass, it will return the last
       part of the plugin's package name, converted to lowercase.  For example,
       YourApp::Cmd::Command::Init will, by default, handle the command "init".

       Subclasses should generally get the superclass value of "command_names" and then append
       aliases.

   usage_desc
       This method should be overridden to provide a usage string.  (This is the first argument
       passed to "describe_options" from Getopt::Long::Descriptive.)

       If not overridden, it returns "%c COMMAND %o";  COMMAND is the first item in the result of
       the "command_names" method.

   opt_spec
       This method should be overridden to provide option specifications.  (This is list of
       arguments passed to "describe_options" from Getopt::Long::Descriptive, after the first.)

       If not overridden, it returns an empty list.

   validate_args
         $command_plugin->validate_args(\%opt, \@args);

       This method is passed a hashref of command line options (as processed by
       Getopt::Long::Descriptive) and an arrayref of leftover arguments.  It may throw an
       exception (preferably by calling "usage_error", below) if they are invalid, or it may do
       nothing to allow processing to continue.

   usage_error
         $self->usage_error("This command must not be run by root!");

       This method should be called to die with human-friendly usage output, during
       "validate_args".

   abstract
       This method returns a short description of the command's purpose.  If this method is not
       overridden, it will return the abstract from the module's Pod.  If it can't find the
       abstract, it will look for a comment starting with "ABSTRACT:" like the ones used by
       Pod::Weaver::Section::Name.

   description
       This method should be overridden to provide full option description. It is used by the
       built-in help command.

       If not overridden, it returns an empty string.
