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.

PAST Optimization

One of the advantages of a common virtual machine for various languages is the ability to apply the same optimizations to all of those languages. For example, LLVM includes optimization passes to propagate constants, eliminate dead arguments, code, and globals, inline functions, and eliminate recursive tail calls, among others. Any language with a compiler to LLVM can easily take advantage of these optimizations without any additional work by the compiler writer.

What is NFG and why you want Parrot to have it.

The Grapheme Normal Form for Unicode (or NFG as we like to call it) has been specified as a feature parrot wants for a long time, it's been in the Parrot Design Document for strings since before I had a commit bit, or any involvement in the project come to that. Something that has gone that long unimplemented can't be that important, right? I mean, we clearly have survived without it. Turns out it is important, but it takes some background to realize why.

2009 Members' Meeting Minutes

The Parrot Foundation held its annual members' meeting on August 25th, 2009 at 2pm Pacific time in Seattle, Washington, USA. Jerry Gay presided over the meeting. Allison Randal prepared these minutes.

How to Get Involved

Discussion about Parrot development normally takes place in two places:

  1. The parrot-dev mailing list:

    Subscribe to the list through the web interface, or go to the Google Group for a searchable archive and RSS/Atom feed.

  2. And on IRC in #parrot at irc.parrot.org.

There is documentation in the docs subdirectory of the Parrot source from the latest release.
