| Summary : use both positional and named arguments in a subroutine
|
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.
Usage is as follows:
sub my_sub {
%vals = Params( AATTtemplate )->args( AATTargs );
...
}
The C< AATTtemplate> specifies the names of parameters in the order that they
should be given in subroutine calls, and C< AATTargs> is the list of argument
to be parsed: usually you just specify the void list C< AATT_>.
The keys in the returned hash C< %vals> are assigned to the appropriate
arguments, irrespective of calling style.
Names may be called with an optional initial dash, as with
L< Getargs::Mixed>:
my_sub( -first => 1, -second => 2 );
Smart parameters can be used for method calls:
sub my_method {
my $self = shift;
%vals = Params( AATTtemplate )->args( AATTargs );
...
}
The values may also contain additional keys which begin with an underscore.
These are internal/diagnostic values:
* _named
True if the parameters were treated as named, false if positional. See
L< /CAVEATS> below.
To improve performance, C< Params> memoizes parameter templates when they
are parsed, based on where the call to C< Params> was made.
This may be problematic if templates are changed dynamically. To override
memoization, use ParamsNC function:
%vals = ParamsNC( AATTtemplate )->args( AATT_ );
There are two styles of templates, L< /Simple Parameter Templates> with a
Perl6-like syntax, and L< /Complex Parameter Templates> which allow more
options to be specified using hashes.
