AppConfig::Getopt - Perl5 module for processing command line arguments via delegation to Getopt::Long. use AppConfig::Getopt; my $state = AppConfig::State->new(\%cfg); my $getopt = AppConfig::Getopt->new($state); $getopt->parse(\@args); # read args 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.

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. Andy Wardley, <abw@wardley.org> $Revision: 1.60 $ Copyright (C) 1997-2003 Andy Wardley.
