What's this? 
Most language implementations that target parrot are listed here. At least the implementations that live in the 'languages' directory of the parrot repository should be covered.
No author information is given here. This is because maintainers should be tracked in the respective languages/*/MAINTAINER files, and we don't want to repeat ourselves.
For current status of some languages see also http://smoke.parrotcode.org/smoke/
Languages that work with the unified languages test suite will have their test results listed under the smokes marked 'languages'.

and I am discussing these issues on the
chicken-users and parrot-internals mailing lists.

Jako
- Description
- C/Perl like language, first compiler for Parrot. The intent is to have a block-structured language that is higher level than IMC, but still exposes the underlying virtual machine rather directly, in the hope that this will eventually be useful for coding extensions to the VM in a language more natural than IMC.
- See also http://en.wikipedia.org/wiki/Jako_(programming).
- Status
- The compiler Works, and the language and examples include subroutines and global constants and variables. NCI also works. The Jako examples are tested during smoke testing. The 'queens' example currently has problems and is therefore not tested.
- Has a low-tech hand-coded lexer and parser, and the ability to spit out the parse tree as XML for debugging. Syntax is a bit rigid, but includes forms that will be familiar to Perl programmers.
- Part of languages smoke testing.

Kea Common Lisp
- Description
- Kea Common Lisp is an implementation of ANSI Common Lisp that is based on CMU Common Lisp (see http://www.cons.org/cmucl/). The chief goal of the Kea Common Lisp project is to provide easy interoperability between Lisp and the other dynamic languages hosted on Parrot.
- Status
- The runtime is incomplete, being at the level of a simple desk calculator with an eccentric syntax, but the cross-compiler already supports most of the core semantic repertoire. The cross-compiler is almost capable of compiling itself; when that happens, EVAL will become suddenly much more powerful, and Kea will be able to grow rapidly.

Defunct languages
This section will eventually be removed, for now serves as a pointer to some older implementations.
Parakeet
Parakeet was a Forth that was extremely machine specific to the Parrot VM. Parakeet also had a lot of features not found in standard Forth, like local variables, nested words and classes and (as a result) nested compile-time and run-time lexical word, class and variable scopes.
Removed from the repository (languages/parakeet) prior to 0.4.10, after having been broken since 0.0.11.
BASIC/interpreter
BASIC interpreter was written in PASM, and used the global stack. It was last verified working in 0.0.11 before it was removed from languages/BASIC/interpreter prior to 0.5.1.
Cardinal
The version at http://rubyforge.org/projects/cardinal/ has been superseded by the one in the repository. (See above)
Perl 5
From r16836 up to r25231 languages/perl5 served as a repository for some Perl 5 - specific functionality that was heavily used in early parrot development.
Pint
An experimental implementation of PHP. Described at http://www.akbkhome.com/blog.php/View/44/Latest_in_Vapourware_PintCompiler__dbdo.html, but no updates since August 2004, and the link to source is a 404.
Ruby
Removed from trunk of Parrot subversion repository. Up to revision 12805, located in languages/ruby.
SFL
Simple functional language. A quickly abandoned attempt. See http://www.acooke.org/andrew/writing/parrot/sfl.html
Span
Span can be most concisely described as Smalltalk for C++, C#, and Java programmers. It features an object system modeled on the Smalltalk object system and a language syntax designed to be easy to learn for developers of C-like languages. Last verified against parrot 0.1.11. http://homepage.mac.com/matt.kennedy/Span
