[Chicken-users] Chicken 1.89 has been released.
Mon, 10 Jan 2005 23:53:30 +0100
The CHICKEN Scheme-to-C compiler, Version 1, Build 89 is now
available at <http://www.call-with-current-continuation.org>.
Things changed since the last release (1.66):
- Countless bugfixes
* Added `-csc-option', `-dont-ask' and `-no-install' options
* chicken-setup and eggs are now basically usable on Windows systems
(for those extensions
that are portable)
- Runtime system:
* The assembly language hack required for calling procedures with
more than 126
arguments on x86 systems has been removed due to portability issues (so the
argument count limit also applies to x86 platforms)
* finalizer handling is much more efficient now
* Threads are not blocked in the REPL [using a neat hack originally
by Chris Double]
* `usual-integrations' is now the default; the `-usual-integrations'
been removed and `-no-usual-integrations' has been added (pass
this option to
the compiler or use declarations to enable redefinition of standard and/or
core library procedures)
* Declaration specifier `post-process'
- library unit:
* fxand fxior fxxor fxnot fxshr fxshl
* `bitwise-...' and `arithmetic-shift' operations now accept inexact
integers when in
machine word range
- utils unit:
* shift! unshift!
- posix unit:
* memory-mapped-file? set-root-directory!
* The posix unit is now partially available on native Windows (MSVC) platforms
[many thanks to Sergey Khorev!]
- regex unit:
* `regexp' accepts optional arguments for case-insensitivity and
(not fully supported on all systems) [Kindly contributed by Alex Shinn]
* The C parser now supports in/out/in-out arguments with multiple
values and basic support
for structs and unions
* `#\xXX' character syntax
* added SRFI-55
* removed last remnants of SRFI-22
- Numerous small improvements and corrections

for their helpful contributions, suggestions and bug reports!
- Generates tail-recursive C with full support for first-class
continuations and multiple values (Using the translation
scheme as described in Henry Baker's paper "Cheney on the M.T.A.").
- Fairly R5RS compliant.
- Support for SRFIs 0, 1, 2, 4, 6, 8, 9, 10, 13, 14, 16, 18, 23, 25,
26, 28, 30, 37, 39 and 55.
- Record structures, hash-tables, queues, custom I/O ports, extended string
operations, regular expressions, Common LISP style `format', TCP sockets and
- Provides an object system with multiple inheritance, multimethods and a
Meta-Object-Protocol (based on Gregor Kiczales' TinyCLOS).
- Lightweight threads (based on call/cc).
- High portability (known to work on Windows, Linux, Free/Net/Open BSD,
Solaris, SunOS, MAC OS X, HP-UX, IRIX and probably many more. Supported
processors include x86, AMD64, Sparc, PA-RISC, Alpha, ARM, IA64, S/390, MIPS
- Freely available under the BSD license.
- A POSIX interface.
- Powerful pattern matching macros.
- `syntax-case' macros and module system
- Generation of profiling information.
- A extensive Foreign Function Interface with callbacks, finalization,
user defined foreign type converters, locatives, embedding of C code inside
Scheme programs, statically allocated (non GC'd) Scheme data and the
possibility of embedding compiled Scheme code into other applications.
- On many systems compiled code can be loaded dynamically into a running
- The compiler can be customized in various ways.
- Support for writing interpreted or compiled UNIX shell scripts or
Windows batch files.
- No unlimited-precision integers (bignums), rationals or complex numbers.
- No support for unicode.
- Procedures can not have more than 126 arguments.
- Compilation of large files is quite slow.
