V6 (Perl)

From Wikipedia, the free encyclopedia

The correct title of this article is v6 (Perl). The initial letter is shown capitalized due to technical restrictions.

This article is about the Perl module. For other uses, see V6 (disambiguation).

v6 is a Perl module which runs under Perl version 5, and transforms Perl 6 code into Perl 5 code on the fly. To quote the release notes:

In summary: Perl 5 is now a first-class virtual machine for Pugs, and in this journey toward self-hosting, we will share as much common structure as possible between the Perl 5, Haskell, and the Parrot runtimes. ^[1]

[edit] Components

v6 is comprised of many parts, divided into a stack of services which can be used to write Perl 6 code directly, or to implement Perl 6 features in Perl 5 programs.

[edit] Moose

Moose and other modules such as Class::MOP provide a low-level emulation of Perl 6's object model and meta-object protocol. This object model can be used directly or through v6.

[edit] Pugs::Grammar::Rule

Pugs::Grammar::Rule provides access to Perl 6's "rules", which are a superset of classic regex functionality which allow the development of entire grammars.

[edit] Data::Bind

Data::Bind provides the parameter binding features of Perl 6, including named parameters.

[edit] Module::Compile

Module::Compile is like a source-filter, but is safer for real-world code development. It is this module which allows v6 to parse Perl 6 code and directly translate it into Perl 5 code which is then executed.
