NAME

    Params::Smart - use both positional and named arguments in a subroutine
    (deprecated)

REQUIREMENTS

    The following non-core modules are required:

      Regexp::Common

INSTALLATION

    Installation can be done using the traditional Makefile.PL method:

      perl Makefile.PL
      make test
      make install

SYNOPSIS

      use Params::Smart 0.04;
    
      sub my_sub {
        %args = Params(qw( foo bar ?bo ?baz ))->args(@_);
        ...
      }
    
      my_sub( foo=> 1, bar=>2, bo=>3 );  # call with named arguments
    
      my_sub(1, 2, 3);                   # same, with positional args

STATUS

    This module is deprecated.

    It has had no significant updates since 2007.

DESCRIPTION

    This module provides "smart" parameter handling for subroutines without
    having to use a changed syntax or source filters. Features include:

      * Mixed use of named and positional parameters.

      * Type checking and coercion through callbacks.

      * Dyanmic parameters configured from callbacks.

      * Memoization of parameter templates.

 Compatability with Previous Versions

    Note that the formatting for simple parameter templates has changed
    since version 0.03, and the complex parameter templates were not
    implemented until version 0.04, so it is best to specify a minimum
    version in use statements

      use Params::Smart 0.04;
    
    
      0.08  Wed Mar 21 2007
    
            - added case where undef value used in positional parameter
    
                (thanks to Rick Westerman)
    
            - minor reorganization of POD
    
      

SEE ALSO

    This module is superficially similar in function to Getargs::Mixed but
    does not require named parameters to have an initial dash ('-').

    Class::NamedParams provides a framework for implementing named
    parameters in classes.

    Sub::NamedParams will create a named-parameter wrapper around
    subroutines which use positional parameters.

    The syntax of the parameter templates is inspired by Perl6::Subs,
    though not necessarily compatible. (See also Apocalypse 6 in
    Perl6::Bible).

    Sub::Usage inspired the error-messages returned by calls to arg().

    Params::Validate is useful for (additional) parameter validation beyond
    what this module is capable of.

    Class::ParmList provides a framework for parameter validation as well.
