App::Cmd::Command::help(3pm)				User Contributed Perl Documentation			      App::Cmd::Command::help(3pm)

NAME
App::Cmd::Command::help - display a command's help screen VERSION
version 0.318 DESCRIPTION
This command plugin implements a "help" command. This command will either list all of an App::Cmd's commands and their abstracts, or display the usage screen for a subcommand with its description. USAGE
The help text is generated from three sources: o The "usage_desc" method o The "description" method o The "opt_spec" data structure The "usage_desc" method provides the opening usage line, following the specification described in Getopt::Long::Descriptive. In some cases, the default "usage_desc" in App::Cmd::Command may be sufficient and you will only need to override it to provide additional command line usage information. The "opt_spec" data structure is used with Getopt::Long::Descriptive to generate the description of the optons. Subcommand classes should override the "discription" method to provide additional information that is prepended before the option descriptions. For example, consider the following subcommand module: package YourApp::Command::initialize; # This is the default from App::Cmd::Command sub usage_desc { my ($self) = @_; my $desc = $self->SUPER::usage_desc; # "%c COMMAND %o" return "$desc [DIRECTORY]"; } sub description { return "The initialize command prepares the application..."; } sub opt_spec { return ( [ "skip-refs|R", "skip reference checks during init", ], [ "values|v=s@", "starting values", { default => [ 0, 1, 3 ] } ], ); } ... That module would generate help output like this: $ yourapp help initialize yourapp initialize [-Rv] [long options...] [DIRECTORY] The initialize command prepares the application... --help This usage screen -R --skip-refs skip reference checks during init -v --values starting values AUTHOR
