Yo! Version 4.0.0 of CHICKEN, the portable and practical Scheme system has been released. In addition to many bugfixes and cleaning up, it provides the following significant changes:
- PCRE has been replaced by Alex Shinn's excellent "IrRegex" regular expression package (while still being API compatible to the old regular expression subsystem) - New implementations of tools to download, build and install extension libraries, which are easier to use and provide more flexibility (like download extensions via Subversion or installation from a local tree) - The macro system has been completely rewritten and is now fully hygienic with highlevel R5RS "syntax-rules" macros and low level "explicit renaming" macros that allow full control over hygiene; "define-macro" is not available anymore - A module system has been implemented that fully supports hygienic macros, and still integrates with separate and cross compilation; module- and syntax meta-information is not retained in compiled run-time code, unless explicitly enabled by the user - A new optimization mode "local" enables inlining of definitions that are visible from other compilation units but not globally modified - Better support for building and using CHICKEN on Windows (mingw and MSYS) - Experimental support for cross-module inlining CHICKEN 4.0.0 can be downloaded from: http://www.call-with-current-continuation.org/chicken-4.0.0.tar.gz CHICKEN-related mailing lists can be found here: http://mail.nongnu.org/mailman/listinfo/chicken-users http://mail.nongnu.org/mailman/listinfo/chicken-hackers To follow the latest development, check out https://galinha.ucpel.tche.br/svn/chicken-eggs Special thanks to Alaric for providing this read-only svn mirror (updated daily): http://chicken.kitten-technologies.co.uk/svn Send bug reports to to <chicken-janit...@nongnu.org> or use the `chicken-bug' program.
