Hi All,

AppConfig::Getopt(3) User Contributed Perl Documentation AppConfig::Getopt(3)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 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.
The first (non-list reference) parameters may contain a number of configuration strings to pass to Getopt::Long::Configure. A reference to
a list of arguments may additionally be passed or @ARGV is used by default.
$getopt->parse(); # uses @ARGV
$getopt->parse(@myargs);
$getopt->parse(qw(auto_abbrev debug)); # uses @ARGV
$getopt->parse(qw(debug), @myargs);
See Getopt::Long for details of the configuartion options available.
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.
See AppConfig for information about using the AppConfig::Getopt module via the getopt() method.
