MiniPerl6 (mp6) is a subset of Perl 6, which was designed as a light bootstrapping language. The initial bootstrap used v6.pm and was then self-hosted in Perl 5.
MiniPerl6 is now self-hosted both in SBCL Lisp and in Perl 5. A developer can modify the compiler source code (written in MiniPerl6) and recompile either with the Perl 5 or with the SBCL backend. The backends can cross-compile to each other. MiniPerl6 can be downloaded from the Pugs repository: $ svn checkout http://svn.pugscode.org/pugs pugs $ cd pugs/v6/v6-MiniPerl6 You can create an executable binary using these commands: $ sh lisp-util/create-core-image.sh $ sbcl --load mp6-lisp-create-core-image.lisp $ chmod +x mp6-lisp $ ./mp6-lisp -e ' class Main { say "hello, World!" } ' ... lisp compiler warnings hello, World! The bootstrapping procedure for both "perl" and "lisp" backends can be tested with: $ sh perl5-util/bootstrap-perl5.sh $ diff -r lib5 lib5-tmp # should show no differences $ sh lisp-util/bootstrap-lisp.sh ... lisp compiler warnings $ diff -r liblisp liblisp-tmp # should show no differences Links: 2006.11.04 MiniPerl6 compiler structure http://pugs.blogs.com/photos/visiolization/mp6bootstrap.html 2006.11.02 - MiniPerl6 design http://pugs.blogs.com/pugs/2006/11/miniperl6_and_u.html 2007.10.19 - KindaPerl6 in Lisp (KindaPerl6 is a Perl 6 compiler written in MiniPerl6) http://pugs.blogs.com/pugs/2007/10/kindaperl6-now-.html v6.pm (Perl 6 in Perl 5) http://search.cpan.org/dist/v6/lib/v6.pm - Flávio S.
