83 | =head1 NAME |
84 | |
85 | MooseX::Getopt::Parser::Long - A Getopt::Long parser for MooseX::Getopt |
86 | |
87 | =head1 SYNOPSIS |
88 | |
89 | use MooseX::Getopt::Parser::Long; |
90 | |
91 | my $parser = MooseX::Getopt::Parser::Long->new( config => ['pass_through'] ); |
92 | my $getopt = MooseX::Getopt::Session->new( parser => $parser ); |
93 | my $app = My::App->new( getopt => $getopt ); |
94 | |
95 | =head1 DESCRIPTION |
96 | |
97 | This class does L<MooseX::Getopt::Parser> for L<MooseX::Getopt>. This |
98 | class is used by default if L<Getopt::Long::Descriptive> module is |
99 | missing. |
100 | |
101 | =head1 METHODS |

103 | =over 4 |
104 | |
105 | =item B<build_options ($getopt, @attrs)> |
106 | |
107 | This method parses the CLI options with L<Getopt::Long> and returns a hashref to options list. |
108 | |
109 | The first argument have to be L<MooseX::Getopt::Session> object and |
110 | second argument is a list of attributes which contains options. |
111 | |
112 | =item B<config> |
113 | |
114 | This accessor contains the arrayref to list with special configuration |
115 | keywords for L<Getopt::Long>. |
