NAME

Getopt::Complete::Args - a set of option/value pairs

VERSION

This document describes Getopt::Complete::Args 0.26.

SYNOPSIS

This is used internally by Getopt::Complete during compile.

A hand-built implementation might use the objects directly, and look like this:

 # process @ARGV...
 
 my $args = Getopt::Complete::Args->new(
    options => [                            # or pass a Getopt::Complete::Options directly                          
        'myfiles=s@' => 'f',
        'name'       => 'u',
        'age=n'      => undef,
        'fast!'      => undef,
        'color'      => ['red','blue','yellow'],
    ]
    argv => \@ARGV
 );
 $args->options->handle_shell_completion;   # support 'complete -F _getopt_complete myprogram'
 if (my @e = $args->errors) {
    for my $e (@e) {
        warn $e;
    }
    exit 1; 
 }
 # on to normal running of the program...
 for my $name ($args->option_names) {
    my $spec = $args->option_spec($name);
    my $value = $args->value($name);
    print "option $name has specification $spec and value $value\n";
 }

DESCRIPTION

An object of this class describes a set of option/value pairs, built from a Getopt::Complete::Options object and a list of command-line arguments (@ARGV).

This is the class of the $Getopt::Complete::ARGS object, and $ARGS alias created at compile time. It is also the source of the %ARGS hash injected into both of those namepaces at compile time.

METHODS

argv

Returns the list of original command-line arguments.

options

Returns the Getopt::Complete::Options object which was used to parse the command-line.

value($option_name)

Returns the value for a given option name after parsing.

bare_args

Returns the bare arguments. The same as ->value('<>')

parent_sub_commands

When using a tree of sub-commands, gives the list of sub-commands selected, in order to get to this point. The options and option/value pairs apply to just this particular sub-command.

The same as ->value('>').

Distinct from ->sub_commands(), which returns the list of next possible choices when drilling down.

option_spec($name)

Returns the GetOptions specification for the parameter in question.

completion_handler($name)

Returns the arrayref or code ref which handles resolving valid completions.

sub_commands

The list of sub-commands which are options at this level of a command tree.

This is distinct from sub_command_path, which are the sub-commands which were chosen to get to this level in the tree.
