NAME

       MooseX::Param - Simple role to provide a standard param method

SYNOPSIS

	 package My::Template::System;
	 use Moose;

	 with 'MooseX::Param';

	 # ...

	 my $template = My::Template::System->new(
	     params => {
		 foo => 10,
		 bar => 20,
		 baz => 30,
	     }
	 );

	 # fetching params
	 $template->param('foo'); # 10

	 # getting list of params
	 $template->param(); # foo, bar, baz

	 # setting params
	 $template->param(foo => 30, bar => 100);

DESCRIPTION

       This is a very simple Moose role which provides a CGI like "param" method.

       I found that I had written this code over and over and over and over again, and each time it was the same. So I thought, why not put it in
       a role?

ATTRIBUTES

       params
	   This role provides a "params" attribute which has a read-only accessor, and a HashRef type constraint. It also adds a builder method
	   (see "init_params" method below) to properly initialize it.

METHODS

       params
	   Return the HASH ref in which the parameters are stored.

       param
	   This is your standard CGI style "param" method. If passed no arguments, it will return a list of param names. If passed a single name
	   argument it will return the param associated with that name. If passed a key value pair (or set of key value pairs) it will assign them
	   into the params.

       init_params
	   This is the params attribute "builder" option, so it is called the params are initialized.

	   NOTE: You can override this by defining your own version in your class, because local class methods beat role methods in composition.

       meta
	   Returns the role metaclass.

SIMILAR MODULES

       The "param" method can be found in several other modules, such as CGI, CGI::Application and HTML::Template to name a few. This is such a
       common Perl idiom that I felt it really deserved it's own role (if for nothing more than I was sick of re-writing and copy-pasting it all
       the time).

       There are also a few modules which attempt to solve the same problem as this module. Those are:

       Class::Param
	   This module is much more ambitious than mine, and provides much deeper functionality. For most of my purposes, this module would have
	   been overkill, but if you need really sophisticated param handling and the ability to provide several different APIs (tied, etc), this
	   module is probably the way to go.

       Mixin::ExtraFields::Param
	   This module is very similar to mine, but for a different framework. It works with the Mixin::ExtraFields framework.

BUGS

       All complex software has bugs lurking in it, and this module is no exception. If you find a bug please either email me, or add the bug to
       cpan-RT.

NAME

       MooseX::Getopt::Meta::Attribute::NoGetopt - Optional meta attribute for ignoring parameters

VERSION

       version 0.59

SYNOPSIS

	 package App;
	 use Moose;

	 with 'MooseX::Getopt';

	 has 'data' => (
	     metaclass => 'NoGetopt',  # do not attempt to capture this param
	     is        => 'ro',
	     isa       => 'Str',
	     default   => 'file.dat',
	 );

DESCRIPTION

       This is a custom attribute metaclass which can be used to specify that a specific attribute should not be processed by "MooseX::Getopt".
       All you need to do is specify the "NoGetopt" metaclass.

	 has 'foo' => (metaclass => 'MooseX::Getopt::Meta::Attribute::NoGetopt', ... );

   Use 'traits' instead of 'metaclass'
       You should rarely need to explicitly set the attribute metaclass. It is much preferred to simply provide a trait (a role applied to the
       attribute metaclass), which allows other code to further modify the attribute by applying additional roles.

       Therefore, you should first try to do this:

	 has 'foo' => (traits => ['NoGetopt', ...], ...);

   Custom Metaclass alias
       This now takes advantage of the Moose 0.19 feature to support custom attribute metaclass. This means you can also use this as the NoGetopt
       alias, like so:

	 has 'foo' => (metaclass => 'NoGetopt', cmd_flag => 'f');
