=head1 NAME

MouseX::Getopt - A Mouse role for processing command line options

=head1 SYNOPSIS

  ## In your class
  package My::App;
  use Mouse;

  with 'MouseX::Getopt';

  has 'out' => (is => 'rw', isa => 'Str', required => 1);
  has 'in'  => (is => 'rw', isa => 'Str', required => 1);

  # ... rest of the class here

  ## in your script
  #!/usr/bin/perl

  use My::App;

  my $app = My::App->new_with_options();
  # ... rest of the script here

  ## on the command line
  % perl my_app_script.pl -in file.input -out file.dump

=head1 DESCRIPTION

This is a role which provides an alternate constructor for creating
objects using parameters passed in from the command line.

This module attempts to DWIM as much as possible with the command line
params by introspecting your class's attributes. It will use the name
of your attribute as the command line option, and if there is a type
constraint defined, it will configure Getopt::Long to handle the option
accordingly.

You can use the trait L<MouseX::Getopt::Meta::Attribute::Trait> or the
attribute metaclass L<MouseX::Getopt::Meta::Attribute> to get non-default
commandline option names and aliases.

You can use the trait L<MouseX::Getopt::Meta::Attribute::Trait::NoGetopt>
or the attribute metaclass L<MouseX::Getopt::Meta::Attribute::NoGetopt>
to have C<MouseX::Getopt> ignore your attribute in the commandline options.

By default, attributes which start with an underscore are not given
commandline argument support, unless the attribute's metaclass is set
to L<MouseX::Getopt::Meta::Attribute>. If you don't want your accessors
to have the leading underscore in their name, you can do this:

  # for read/write attributes
  has '_foo' => (accessor => 'foo', ...);

  # or for read-only attributes
  has '_bar' => (reader => 'bar', ...);

This will mean that Getopt will not handle a --foo param, but your
code can still call the C<foo> method.

If your class also uses a configfile-loading role based on
L<MouseX::ConfigFromFile>, such as L<MouseX::SimpleConfig>,
L<MouseX::Getopt>'s C<new_with_options> will load the configfile
specified by the C<--configfile> option (or the default you've
given for the configfile attribute) for you.

Options specified in multiple places follow the following
precedence order: commandline overrides configfile, which
overrides explicit new_with_options parameters.

=head2 Supported Type Constraints

=over 4

=item I<Bool>

A I<Bool> type constraint is set up as a boolean option with
Getopt::Long. So that this attribute description:

  has 'verbose' => (is => 'rw', isa => 'Bool');

would translate into C<verbose!> as a Getopt::Long option descriptor,
which would enable the following command line options:

  % my_script.pl --verbose
  % my_script.pl --noverbose

=item I<Int>, I<Float>, I<Str>

These type constraints are set up as properly typed options with
Getopt::Long, using the C<=i>, C<=f> and C<=s> modifiers as appropriate.

=item I<ArrayRef>

An I<ArrayRef> type constraint is set up as a multiple value option
in Getopt::Long. So that this attribute description:

  has 'include' => (
      is      => 'rw',
      isa     => 'ArrayRef',
      default => sub { [] }
  );

would translate into C<includes=s@> as a Getopt::Long option descriptor,
which would enable the following command line options:

  % my_script.pl --include /usr/lib --include /usr/local/lib

=item I<HashRef>

A I<HashRef> type constraint is set up as a hash value option
in Getopt::Long. So that this attribute description:

  has 'define' => (
      is      => 'rw',
      isa     => 'HashRef',
      default => sub { {} }
  );

would translate into C<define=s%> as a Getopt::Long option descriptor,
which would enable the following command line options:

  % my_script.pl --define os=linux --define vendor=debian

=head2 Custom Type Constraints

It is possible to create custom type constraint to option spec
mappings if you need them. The process is fairly simple (but a
little verbose maybe). First you create a custom subtype, like
so:

  subtype 'ArrayOfInts'
      => as 'ArrayRef'
      => where { scalar (grep { looks_like_number($_) } @$_)  };

Then you register the mapping, like so:

  MouseX::Getopt::OptionTypeMap->add_option_type_to_map(
      'ArrayOfInts' => '=i@'
  );

Now any attribute declarations using this type constraint will
get the custom option spec. So that, this:

  has 'nums' => (
      is      => 'ro',
      isa     => 'ArrayOfInts',
      default => sub { [0] }
  );

Will translate to the following on the command line:

  % my_script.pl --nums 5 --nums 88 --nums 199

This example is fairly trivial, but more complex validations are
easily possible with a little creativity. The trick is balancing
the type constraint validations with the Getopt::Long validations.

Better examples are certainly welcome :)

=head2 Inferred Type Constraints

If you define a custom subtype which is a subtype of one of the
standard L</Supported Type Constraints> above, and do not explicitly
provide custom support as in L</Custom Type Constraints> above,
MouseX::Getopt will treat it like the parent type for Getopt
purposes.

For example, if you had the same custom C<ArrayOfInts> subtype
from the examples above, but did not add a new custom option
type for it to the C<OptionTypeMap>, it would be treated just
like a normal C<ArrayRef> type for Getopt purposes (that is,
C<=s@>).

=head1 METHODS

=head2 B<new_with_options (%params)>

This method will take a set of default C<%params> and then collect
params from the command line (possibly overriding those in C<%params>)
and then return a newly constructed object.

The special parameter C<argv>, if specified should point to an array
reference with an array to use instead of C<@ARGV>.

If L<Getopt::Long/GetOptions> fails (due to invalid arguments),
C<new_with_options> will throw an exception.

If L<Getopt::Long::Descriptive> is installed and any of the following
command line params are passed, the program will exit with usage
information (and the option's state will be stored in the help_flag
attribute). You can add descriptions for each option by including a
B<documentation> option for each attribute to document.

  --?
  --help
  --usage

If you have L<Getopt::Long::Descriptive> the C<usage> param is also passed to
C<new> as the usage option.

=head2 B<ARGV>

This accessor contains a reference to a copy of the C<@ARGV> array
as it originally existed at the time of C<new_with_options>.

=head2 B<extra_argv>

This accessor contains an arrayref of leftover C<@ARGV> elements that
L<Getopt::Long> did not parse.  Note that the real C<@ARGV> is left
un-mangled.

=head2 B<usage>

This accessor contains the L<Getopt::Long::Descriptive::Usage> object (if
L<Getopt::Long::Descriptive> is used).

=head2 B<help_flag>

This accessor contains the boolean state of the --help, --usage and --?
options (true if any of these options were passed on the command line).

=head2 B<meta>

This returns the role meta object.
