90 | =head1 NAME |
91 | |
92 | MooseX::Getopt::Parser::Long - A Getopt::Long parser for MooseX::Getopt |
93 | |
94 | =head1 SYNOPSIS |
95 | |
96 | use MooseX::Getopt::Parser::Long; |
97 | |
98 | my $parser = MooseX::Getopt::Parser::Long->new( config => ['pass_through'] ); |
99 | my $getopt = MooseX::Getopt::Session->new( parser => $parser ); |
100 | my $app = My::App->new( getopt => $getopt ); |
101 | |
102 | =head1 DESCRIPTION |
103 | |
104 | This class does L<MooseX::Getopt::Parser> for L<MooseX::Getopt>. This |
105 | class is used by default if L<Getopt::Long::Descriptive> module is |
106 | missing. |
107 | |
108 | =head1 METHODS |

110 | =over 4 |
111 | |
112 | =item B<build_options ($getopt, @attrs)> |
113 | |
114 | This method parses the CLI options with L<Getopt::Long> and returns a hashref to options list. |
115 | |
116 | The first argument have to be L<MooseX::Getopt::Session> object and |
117 | second argument is a list of attributes which contains options. |
118 | |
119 | =item B<config> |
120 | |
121 | This accessor contains the arrayref to list with special configuration |
122 | keywords for L<Getopt::Long>. |
