CPANPLUS::Shell::Default::Plugins::HOWTO(3pm) Perl Programmers Reference Guide CPANPLUS::Shell::Default::Plugins::HOWTO(3pm) NAME
CPANPLUS::Shell::Default::Plugins::HOWTO -- documentation on how to write your own plugins SYNOPSIS
package CPANPLUS::Shell::Default::Plugins::MyPlugin; ### return command => method mapping sub plugins { ( myplugin1 => 'mp1', myplugin2 => 'mp2' ) } ### method called when the command '/myplugin1' is issued sub mp1 { .... } ### method called when the command '/? myplugin1' is issued sub mp1_help { return "Help Text" } DESCRIPTION
This pod text explains how to write your own plugins for "CPANPLUS::Shell::Default". HOWTO
Registering Plugin Modules Plugins are detected by using "Module::Pluggable". Every module in the "CPANPLUS::Shell::Default::Plugins::*" namespace is considered a plugin, and is attempted to be loaded. Therefor, any plugin must be declared in that namespace, in a corresponding ".pm" file. Registering Plugin Commands To register any plugin commands, a list of key value pairs must be returned by a "plugins" method in your package. The keys are the commands you wish to register, the values are the methods in the plugin package you wish to have called when the command is issued. For example, a simple 'Hello, World!' plugin: package CPANPLUS::Shell::Default::Plugins::HW; sub plugins { return ( helloworld => 'hw' ) }; sub hw { print "Hello, world! " } When the user in the default shell now issues the "/helloworld" command, this command will be dispatched to the plugin, and its "hw" method will be called Registering Plugin Help To provide usage information for your plugin, the user of the default shell can type "/? PLUGIN_COMMAND". In that case, the function "PLUGIN_COMMAND_help" will be called in your plugin package. For example, extending the above example, when a user calls "/? helloworld", the function "hw_help" will be called, which might look like this: sub hw_help { " /helloworld # prints "Hello, world! " } If you dont provide a corresponding _help function to your commands, the default shell will handle it gracefully, but the user will be stuck without usage information on your commands, so it's considered undesirable to omit the help functions. Arguments to Plugin Commands Any plugin function will receive the following arguments when called, which are all positional: Classname -- The name of your plugin class Shell -- The CPANPLUS::Shell::Default object Backend -- The CPANPLUS::Backend object Command -- The command issued by the user Input -- The input string from the user Options -- A hashref of options provided by the user For example, the following command: /helloworld bob --nofoo --bar=2 joe Would yield the following arguments: sub hw { my $class = shift; # CPANPLUS::Shell::Default::Plugins::HW my $shell = shift; # CPANPLUS::Shell::Default object my $cb = shift; # CPANPLUS::Backend object my $cmd = shift; # 'helloworld' my $input = shift; # 'bob joe' my $opts = shift; # { foo => 0, bar => 2 } .... } BUG REPORTS
