Parrot 1.4 expands dynamic integrations

The Parrot project has attempted to do the unlikely many times before. This open-source platform for dynamic languages includes the facilities for running existing dynamic languages, such as Perl, Python and Ruby, but also includes the tools for building new languages and providing them with the infrastructure needed to function in almost any environment. This week, the Parrot project will release version 1.4, a major update that achieves many of the interoperability goals initially set by the Parrot team.

The Parrot project has created both a runtime for dynamic languages, like Python and Ruby, and a set of tools for adding new languages. Since the version 1.0 release in May, outside contributors have begun adding languages, such as APL, Lua and SNOBOL. Parrot is also designed to be embedded in other applications and environments as a standalone generic language runtime.

The initial goal of Parrot 1.0 was to give developers a platform on top of which to build languages, without regard to production environments just yet. Patrick Michaud, a contributor to Parrot and the lead developer of Rakudo, the Perl 6 engine based on Parrot, said that the overall goals of Parrot are broader than just having a unified runtime.

“The goal was to provide a platform for dynamic languages and dynamic language development. Perl, Python, Ruby—they all tend to create their own implementation or reinvent each others' wheels, internally," said Michaud. "It was felt we could build a virtual machine that could provide a common layer for all of these for people, so they could focus on language issues.

“These languages would be able to have libraries that could communicate and work together. Let's say I am a Perl programmer, and there's a Python library I can take advantage of. Parrot gives me a common substrate to get those to work together.”

At the head of the project is Allison Randal, chief architect and lead developer for Parrot. She joined the project eight years ago when she became interested in Perl 6, a language that is heavily intertwined with the Parrot project. Today, she's passed from Perl into the actual guts of Parrot, which is written in C.
