NAME

Perl6::Interpolators - Use Perl 6 function-interpolation syntax

SYNOPSIS

        use Perl6::Interpolators;
        sub Foo { 1 }
        sub Bar { 1..5 }
        sub Baz { @_ }
        sub Context { wantarray ? 'list' : 'scalar' }

        print "Foo: $(Foo)\n";                  #prints Foo: 1
        print "Bar: @(Bar)\n";                  #prints Bar: 1 2 3 4 5

        print "Baz: $(Baz('a', 'b'))";          #prints Baz: b
        print "Baz: @(Baz('a', 'b'))";          #prints Baz: a b

        print "$(Context)";                             #prints scalar
        print "@(Context)";                             #prints list

DESCRIPTION

Perl6::Interpolate allows you to interpolate function calls into strings. Because of Perl's contexts, Perl6::Interpolate requires a sigil (a funny character--$ or @ in this case) to tell the function being called which context to use; thus, the syntax is $(call) for scalar context or @(call) for list context. (This syntax is expected to be used for the same thing in Perl 6, too.)

Perl6::Interpolate will work on both fuction and method calls. It will work on parenthesized calls. It even works outside quotes, where it can be used to control context. (This may be the only way to get a list context in some cases, for example.)

BUGS

• Using this module precludes use of $(. However, you can temporarily disable the module while you munge with $(:

          no Perl6::Interpolators;
          #now mess with $(
          use Perl6::Interpolators

• Currently this module will make changes inside single-quoted strings. It won't interpolate a call--it'll just look funny.
