CPANPLUS::Shell::Default::Plugins::HOWTO(3) User Contributed Perl Documentation CPANPLUS::Shell::Default::Plugins::HOWTO(3)
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 don't 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 }
....
}
