NAME

AppConfig::Getopt - Perl5 module for processing command line arguments via delegation to Getopt::Long.

SYNOPSIS

use AppConfig::Getopt;

my $state  = AppConfig::State->new(\%cfg);
my $getopt = AppConfig::Getopt->new($state);

$getopt->parse(\@args);            # read args

OVERVIEW

AppConfig::Getopt is a Perl5 module which delegates to Johan Vroman's Getopt::Long module to parse command line arguments and update values in an AppConfig::State object accordingly.

AppConfig::Getopt is distributed as part of the AppConfig bundle.

DESCRIPTION

USING THE AppConfig::Getopt MODULE

To import and use the AppConfig::Getopt module the following line should appear in your Perl script:

use AppConfig::Getopt;

AppConfig::Getopt is used automatically if you use the AppConfig module and create an AppConfig::Getopt object through the getopt() method.

AppConfig::Getopt is implemented using object-oriented methods. A new AppConfig::Getopt is implemented using object-oriented methods. A new AppConfig::Getopt object is created and initialised using the new() method. This returns a reference to a new AppConfig::Getopt object. A reference to an AppConfig::State object should be passed in as the first parameter:

my $state  = AppConfig::State->new();
my $getopt = AppConfig::Getopt->new($state);

This will create and return a reference to a new AppConfig::Getopt object.

PARSING COMMAND LINE ARGUMENTS

The parse() method is used to read a list of command line arguments and update the state accordingly. A reference to the list of arguments should be passed in or @ARGV is used as the default.

$getopt->parse(\@ARGV);

A Getopt::Long specification string is constructed for each variable defined in the AppConfig::State. This consists of the name, any aliases and the ARGS value for the variable.

These specification string are then passed to Getopt::Long, the arguments are parsed and the values in the AppConfig::State updated.
