- csc.in: `-embedded' wasn't recognized
- library.scm: `get-keyword' accepts any object as keys
- runtime.c: `C_callback' doesn't do a minor GC at entry [Thanks to Bruce Hoult]
- `(. ...)' segfaulted instead of giving an error message [Thanks to Category 5]
- `(receive X)' is allowed and returns the list of the result-values
2003-08-17 flw <flw@gurke>
* /cvsroot/chicken/chicken/eval.scm, /cvsroot/chicken/chicken/runtime.c:
- fixed big performance leak in minor GC handling: GC-timing stuff for `time'
macro caused way too many kernel calls [Thanks to Bruce Hoult]
- `dump_trace()' didn't initialize output buffer properly

- `csc' added `-s' option to linker, when linking with optimization (won't
work when building shared object)
- fixed countless typos in manual.tex [Thanks to Bruce Mitchener]
- `csc' uses `-bundle' instead of `-shared' under Mac OS X

- fixed compiler bug that caused repeated explicit rest-argument list consing
[Thanks to Sven Hartrumpf]

might turn out useful)
- lolevel.scm: `unbound-variable-value'

- extras.scm: `write-string'
- csi doesn't use the lolevel unit anymore
- `chicken-setup.c' was not up to date
- added BOOTSTRAP_PATH to Makefile.am, this simplifies the invocation
of make when bootstrapping the system from CVS sources

- `##sys#thread-block-for-i/o!' for output (or mixed?) mode doesn't work properly (deactived,
does simple polling)

other threads are ready [Thanks to Chris Double]

* /cvsroot/chicken/chicken/Makefile.am:
Undid change that made both MORE_LIBS and MORE_STATIC_LIBS be the same thing.
* /cvsroot/chicken/chicken/Makefile.am:
Made both MORE_LIBS and MORE_STATIC_LIBS be the same thing.
* /cvsroot/chicken/chicken/Makefile.am:
-all-static replaced by -static. On Solaris, need libdl.so and
libnsl.so since no libdl.a nor libnsl.a.
* /cvsroot/chicken/chicken/Makefile.am:
"make doc" and "make testsuites" now use CHICKEN=../chicken
* /cvsroot/chicken/chicken/Makefile.am:
Uses MORE_STATIC_LIBS instead of MORE_LIBS for
lib[xxx_]chicken_la_LDFLAGS so that libtool does not add "-ldl"
whenever something links with lib[xxx-]chicken.la.
* /cvsroot/chicken/chicken/chicken-config.in, /cvsroot/chicken/chicken/configure.in, /cvsroot/chicken/chicken/csc.in, /cvsroot/chicken/chicken/Makefile.am, /cvsroot/chicken/chicken/runtime.c:
configure.in: Made new variable SHLIBS which has -ldl or -ldld, which will only be used in non -all-static code.
Makefile.am: Use SHLIBS to differentiate MORE_LIBS from MORE_STATIC_LIBS.
runtime.c: Do not even try to use dl.h/dlfcn.h/dlopen/shlopen when in all-static mode.
chicken-config.in, csc.in: Use MORE_STATIC_LIBS (%morestaticlibs%) in static mode.
Package changes:
Put documentation in the canonical pkgsrc directories.
Add test target support.
Gmake is not needed anymore.
Things changed in release 1.0:
- Many bugfixes
- Declaration specifier `compress-literals' and compiler-option
`-compress-literals N'
- Chicken now compiles on OpenBSD [Thanks to Steve Elkins]
- `library' unit:
(chicken-version)
- A new version of the portable syntax-case macro system is now used, which
provides `identifier-syntax', `fluid-let-syntax' and `datum->syntax-object',
allows low-level macros (`define-macro') in combination with hygienic
macros and supports the module system used in Chez Scheme (but does not
handle separate compilation)
- The syntax `(define-syntax (name var) ...)' is allowed
- Chicken supports now SRFI-37 officially (A new library unit named `srfi-37'
has been added)
- The old module system has been removed. It was rather hackishly implemented
and didn't integrate well with the highlevel macro system
- The scheduler and the threading system have been massively overhauled
and scale a little better
- The pattern-matcher is now available in combination with the highlevel
macro system, enter `(include "match")' or `(require-for-syntax 'match)'
to make it available
- SRFI-22 script interpreters `scheme-chicken' and `scheme-chicken-hygienic'
have been added
- Compiled `#!' scheme scripts with an invocation line of `csi -script' or
`scheme-chicken'/`scheme-chicken-hygienic' automagically link with all
libraries which would normally be available under the interpreter.
- Type-checks of fixed size objects are slightly more efficient
- Extension-libraries can now be stored alternatively in a directory given
by the CHICKEN_REGISTRY environment variable or in `$HOME/.chicken-registry'
- The new library unit `tcp' provides a PLTish socket interface,
`tcp-accept' and I/O from socket ports do not block other running threads
- The new compiler/interpreter option `-strict-letrec' enables a fully R5RS
compliant expansion of `letrec'
- Chicken should now pass all tests of Scott G. Millers `r5rs_pitfalls.scm'
- Jonah Beckford ported SWIG (<http://www.swig.org>) to Chicken!
Check out a preliminary version at
<http://beckford.netfirms.com/hobbies/swig/>
- On Windows (Cygwin, Mingw32 and MSVC), CHICKEN now supports shared libraries
and dynamic loading. Many thanks to Jonah Beckford for his tremendous work!
Things changed in release 0.1082:
- Bugfixes.
- Support for SRFI's 26 (cut) and 30 (block comments).
- Peter Keller translated the manual into LaTeX. Pdf and html
documentation is available.
- Peter Keller has contributed a comprehensive testing framework
(fully R5RS compliant).
- Declaration specifiers:
export
compile-time-macros-only
- Library unit `extras':
hash-table-remove!
->string
- Library unit `posix':
sleep
- Library unit `lolevel':
pointer-offset
pointer-u8-ref pointer-u8-set!
pointer-s8-ref pointer-s8-set!
pointer-u16-ref pointer-u16-set!
pointer-s16-ref pointer-s16-set!
pointer-u32-ref pointer-u32-set!
pointer-s32-ref pointer-s32-set!
pointer-f32-ref pointer-f32-set!
pointer-f64-ref pointer-f64-set!
- Dynamic loading is now supported on older HP-UX systems that
provide `shl_load()' instead of `dlopen()'
(Thanks to Tony Garnock-Jones)
- Error messages have been (slightly) improved.
- A system for simplified packaging, building and installation
of extension-libraries (based on shared libraries) is now provided.
- New data type `locatives' allow to create pointers into arbitrary
sections of various kinds of Scheme data objects.
- So called `locations' simplify passing pointers to local or global
Scheme variables to foreign procedures.
- FFI-generated code is a little bit more compact and efficient.
- Chicken supports alternative keyword syntaxes (CL/DSSSL) via the
compiler/interpreter option `-keyword-style' and the parameter
`keyword-style'
- `define-record-printer' now handles SRFI-9 record types.
- The regex-libraries now allow the creation of precompiled regular
expressions (new procedures `regexp' and `regexp?').
CHICKEN is a Scheme-to-C compiler supporting most of the language
features as defined in the Revised^5 Report on Scheme. CHICKEN
generates quite portable C code, and files compiled by it (including
itself) should work without any changes on most platforms.
The whole package is distributed under a BSD license and as such free
to use and modify as long as you adhere to its terms (see the manual).
Linkage to C modules and C-library functions is straightforward, so
it's easy to access C from Scheme. Compiled code can be embedded into
existing C programs without problems. The generated code supports
full tail-recursion, first-class continuations, multiple values and
dynamic-wind.
