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

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

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";
 }

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.

Returns the list of original command-line arguments.
Returns the Getopt::Complete::Options object which was used to parse the command-line.
Returns the value for a given option name after parsing.
Returns the bare arguments. The same as ->value('<>')
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.

Returns the GetOptions specification for the parameter in question.
Returns the arrayref or code ref which handles resolving valid completions.
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.
