Parrot is a virtual machine designed to efficiently compile and execute bytecode for dynamic languages. Parrot currently hosts a variety of language implementations in various stages of completion, including Tcl, Javascript, Ruby, Lua, Scheme, PHP, Python, Perl 6, APL, and a .NET bytecode translator. Parrot is not about parrots, though we are rather fond of them for obvious reasons.

Hello Parrot

Hello everybody,
Let me introduce myself. I'm Bart Wiegmans, brrt on irc, and I will be implementing a new mod_parrot this summer, courtesy of google and whiteknight. Which will make it possible to serve parrot-powered web applications once again.

So, who am I? I'm 24 years old and I study biology in Groningen, the Netherlands where I live together with my girlfriend. Aside from that, I work as a programmer for As for hobbies, I play mario kart and pikmin. I used to say I had four pet rats, but unfortunately one of them died just Last weekend.

Parrot 4.0.0 "Hyperstasis" Released!

At one extreme, it is possible to approach the subject on a high mathematical
epsilon-delta level, which generally results in many undergraduate students not
knowing what's going on. At the other extreme, it is possible to wave away all
the subtleties until neither the student nor the teacher knows what's going on.

-Stanley J. Farlow, Preface to Partial Differential Equations for Scientists and

On behalf of the Parrot team, I'm proud to announce Parrot 4.0.0,
also known as "Hyperstasis". Parrot

Parrot 3.11.0 "Duct Tape" Released

"If I had some duct tape, I could fix that."

On behalf of the Parrot team, I'm proud to announce Parrot 3.11.0, also known as "Duct tape". Parrot is a virtual machine aimed at running all dynamic languages.


Guitor Hero

I've created a new project: Guitor, a GUI creaTOR module written in winxed using Xlib via NCI.

It's not much feature complete yet, but has enough funcionality to provide some nice examples, including a viewer for R->R functions and a drawing board.

I've tested only in linux amd64 and i386, so the StructView used may be not appropiate in some platforms, feedback will be appreciated.

Install: winxed setup.winxed install

Run an example: winxed examples/pizarra.winxed


Parrot Documentation Revision Effort (Blog deux)

All and Everyone:

Parrot's current set of documentation is now up on github. Hopefully, this will aid in the documentation revision effort.

To view the html documents, simply navigate your favorite browser to To edit the documentation, simply navigate your browser to, clone the repo, and make your edits (or provide a pull request).

Thank you.


PACT - Disassembler

The first step in generating a packfile is understanding the packfile. So I've been writing a Winxed disassembler. It's pretty fully featured at this point. It's showing constants, annotations, and symbolic instructions. Despite my fears, it turned out that PCC wasn't all that difficult to deal with.

Parrot Documentation Revision Effort (Blog un)

Finally! I have managed to find enough time -- in the wee hours of the morning no less -- and a stable current of electricity -- meaning the power company has finished its little poll-replacement project -- to push a new 'documentation_revisions' branch to the parrot repo. This is the branch from which anyone involved with the documentation revision effort will work. Hopefully, that is, if I've gotten everything correct. (I make no pretensions here to knowing or to understanding, well, how git works.

Parrot for Dummies (which means me! :-)

This is just a quick, first blog post to ensure everything is working correctly.
