Well, you still have to parse/check the input regardless of if you directly parse @ARGV or use the module. There is no reinvention there. That module is to extend the command line options so you can use POSIX syntax with GNU extensions. That being said, I would urge the OP to use the module just to learn the interface for future programs that can really take advantage of it.

Hi,
I would like to parse command line arguments.
The problem I am facing is that I cannot get it right when an option has a optional value.
Example:

# ./ej.pl --remove all
And the script may allow only one option.
So this is wrong:

appconfig::getopt
AppConfig::Getopt(3pm) User Contributed Perl Documentation AppConfig::Getopt(3pm)
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.
