A new AppConfig::Getopt object is created and initialised using the \fBnew()\fR 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: .PP .Vb 2 \& my $state = AppConfig::State\->new(); \& my $getopt = AppConfig::Getopt\->new($state); .Ve .PP This will create and return a reference to a new AppConfig::Getopt object. .SS "\s-1PARSING COMMAND LINE ARGUMENTS\s0" .IX Subsection "PARSING COMMAND LINE ARGUMENTS" The \f(CW\*(C`parse()\*(C'\fR method is used to read a list of command line arguments and update the state accordingly. .PP 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 \f(CW@ARGV\fR is used by default. .PP .Vb 4 \& $getopt\->parse(); # uses @ARGV \& $getopt\->parse(\e@myargs); \& $getopt\->parse(qw(auto_abbrev debug)); # uses @ARGV \& $getopt\->parse(qw(debug), \e@myargs); .Ve .PP See Getopt::Long for details of the configuartion options available. .PP A Getopt::Long specification string is constructed for each variable defined in the AppConfig::State. This consists of the name, any aliases and the \s-1ARGS\s0 value for the variable. .PP These specification string are then passed to Getopt::Long, the arguments are parsed and the values in the AppConfig::State updated. .PP See AppConfig for information about using the AppConfig::Getopt module via the \fBgetopt()\fR method. .SH "AUTHOR" .IX Header "AUTHOR" Andy Wardley, <abw@wardley.org> .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright (C) 1997\-2007 Andy Wardley.
