2015-03-07 Shiro Kawai <shiro@acm.org>
* gc/libatomic_ops/src/atomic_ops/sysdeps/gcc/mips.h:
mips64el support. Patch from James Cogwill.
* src/gauche/priv/portP.h: Fix race condition in PORT_UNLOCK
by adding a memory barrier. Patch from James Cogwill.
2015-03-06 Shiro Kawai <shiro@acm.org>
* ext/sparse/sparse.scm: Add sparse matrix.
2015-03-04 Shiro Kawai <shiro@acm.org>
* ext/sparse/spvec.c: Add default value to sparse vectors.
2015-02-24 Shiro Kawai <shiro@acm.org>
* lib/gauche/cgen/cise.scm: Renamed cgen-context to cgen-ambient,
for the term 'context' is also used in the local C context
(toplevel, stmt, expr) and confusing.
2015-02-22 Shiro Kawai <shiro@acm.org>
* lib/gauche/cgen/stub.scm: During expanding stub procedures
(define-cproc etc) we set up a custom cise context to override
"return" macro; so that we can say (return something) safely
in the stub procedures, instead of (result something), which
is somewhat awkward. The difference from C return is that
it can handle multiple return values.
Note that this 'return' macro really behaves like return---it
skips the rest of the procedure, unlike the 'result' macro that
merely assigns SCM_RESUT values. The code that relies the
'result' macro to continue execution (which is a bad habit)
can't just replace 'result' to 'return'.
2015-02-11 Shiro Kawai <shiro@acm.org>
* ext/net/netaux.scm (make-server-sockets): Handle the case when
port is 0. Also avoid using cond-expand, for this file can be
precompiled on different platform than the target.
2015-02-10 Shiro Kawai <shiro@acm.org>
* ext/net/netaux.scm (make-server-socket): Allow passing multiple
ports and let the function choose an available one.
2015-02-03 Shiro Kawai <shiro@acm.org>
* lib/gauche/common-macros.scm (and-let1): Allow multiple exprs
in body. Added doc (so it's official).
2015-02-01 Shiro Kawai <shiro@acm.org>
* lib/gauche/common-macros.scm (and-let1): Added experimentally.
I feel that I wrote single-binding and-let* enough times.
2015-01-31 Shiro Kawai <shiro@acm.org>
* ext/vport/vport.scm (open-input-char-list, open-input-byte-list):
Added list ports.
* src/liblazy.scm (port->char-lseq, port->byte-lseq, port->string-lseq)
(port->sexp-lseq): Added for the convenience.
2015-01-30 Shiro Kawai <shiro@acm.org>
* src/prof.c (Scm_ProfilerStart): Use Scm_TmpDir to get temporary
directory, instead of hardcoding "/tmp".
2015-01-29 Shiro Kawai <shiro@acm.org>
* src/portapi.c (Scm_UngottenChars, Scm_UngottenBytes): API
to retrieve bufferd chars/bytes. Note that the current getc-ungetc
API may be changed in future, so don't rely on these too much.
(The semantics of "ungetting" isn't well defined, especially when
binary i/o and character i/o are mixed.)
* src/libio.scm (%port-ungotten-chars, %port-ungotten-bytes):
Exposing above in gauche.internal module.
2015-01-24 Shiro Kawai <shiro@acm.org>
* lib/text/gap-buffer (text.gap-buffer): Added experimentally.
2015-01-17 Shiro Kawai <shiro@acm.org>
* src/number.c (Scm_GetIntegerUMod): Added - a convenience routine to
extract lower u_long bits from an exact integer.
2015-01-15 Shiro Kawai <shiro@acm.org>
* lib/srfi-69.scm, src/srfis.scm, test/srfi.scm, doc/modsrfi.texi:
Added srfi-69 support.
2015-01-14 Shiro Kawai <shiro@acm.org>
* lib/gauche/record.scm: Fix a bug when there's one argument
given to the custom constructor.
* src/libvec.scm (%uvector-ref), src/vector.c (Scm_VMUVectorRef):
Fixed a bug that leaked #<unbound>. Patch from wasao.
2015-01-09 Shiro Kawai <shiro@acm.org>
* src/compare.c (comparator_compare): Make equal? to compare
comparator's elements.
2015-01-08 Shiro Kawai <shiro@acm.org>
* lib/srfi-113.scm: Added srfi-113.
2015-01-07 Shiro Kawai <shiro@acm.org>
* src/error.c (Scm_ReportError), src/libexc.scm (report-error):
Added optional sink argument to specify where the message go.
We want to change C API Scm_ReportError accordingly; to keep
0.9 ABI compatibility, there's some transient code in place.
2015-01-06 Shiro Kawai <shiro@acm.org>
* src/compare.c (Scm_Compare): Handle comparison of different
type of objects even if their types are not the one mentioned
in srfi-114.
2015-01-02 Shiro Kawai <shiro@acm.org>
* doc/corelib.texi (report-error): Documented.
2014-12-31 Shiro Kawai <shiro@acm.org>
* ext/threads/threads.c (make-thread): Set custom-error-reporter
of newly created thread to suppress the default error message;
the unhandled error (which causes error message by default)
should be handled by the caller of thread-join!. If one wants
to report an error within the thread, use guard and report-error.
* src/libeval.scm (%vm-custom-error-reporter-set!): Renamed from
vm-set-custom-error-reporter, and moved to gauche.internal module.
This is something you don't need to touch daily, so no reason to
expose it by default.
* src/vm.c (Scm_VMDefaultExceptionHandler),
src/error.c (Scm_ReportError): Instead of calling
vm->customErrorHandler in Scm_ReportError, we lifted the check
to Scm_VMDefaultExceptionHandler; if vm->customErrorHandler is
set, it is called directly, and Scm_ReportError always print
the default message and stack trace. This seems the sane way
to do it - we don't remember why we chose to dispatch inside
Scm_ReportError initially.
* ext/threads/threads.c (Scm_MakeThread): Do not alter
customErrorReporter in the new thread. Instead, we just drop
call of Scm_ReportError in thread_entry. If the programmer
needs the thread to report error, she can call report-error
within guard clauses.
2014-12-30 Shiro Kawai <shiro@acm.org>
* src/gauche/vm.h: INCOMPATIBLE CHANGE: Renamed
ScmVM.defaultEscapeHandler for customErrorReporter. The name was
misleading as if it would handle escaping situation caused by
exceptions; in fact, we have totally separate mechanism to handle
exceptions, and the said slot is merely called by Scm_ReportError,
which is the default action when the exception isn't handled at
all.
ABI compatibility is kept, but any extension code that refers to
this slot would break. Since this is undocumented niche feature,
we hope this won't affect much.
* src/libeval.scm: vm-set-default-exception-handler becomes
vm-set-custom-error-reporter, as well.
2014-12-27 Shiro Kawai <shiro@acm.org>
* lib/Makefile.in: Don't forget to install srfi-18.scm
* ext/threads/threads.scm: Re-export current-thread
2014-12-23 Shiro Kawai <shiro@acm.org>
* src/module.c: Introduced gauche.keyword module to allow R7RS
modules to use keyword default bindings. See the comment.
2014-12-21 Shiro Kawai <shiro@acm.org>
* src/load.c: Support '.sld' suffix by default.
2014-12-18 Shiro Kawai <shiro@acm.org>
* configure.ac, ext/*/*.ac, src/Makefile/in, src/genconfig.in:
Add --static-libs option to gauche-config, which lists all
libraries needed for statically linked binary.
2014-12-17 Shiro Kawai <shiro@acm.org>
* lib/gauche/macroutil.scm (with-renaming): Experimentally added
a utility to construct the result form within er macro transformer.
NB: The old undocumented macros defined in macroutil.scm are removed,
for they aren't used much after all.
2014-12-14 Shiro Kawai <shiro@acm.org>
* lib/gauche/cgen/unit.scm (cgen-safe-name{-friendly}): Allow ':'
to be in C name, so that we can call C++ namespace-qualified
functions.
2014-12-13 Shiro Kawai <shiro@acm.org>
* lib/data/heap.scm (binary-heap-swap-{min|max}!): Added.
2014-12-12 Shiro Kawai <shiro@acm.org>
* lib/gauche/configure.scm (parse-command-line-arguments):
Made ./configure -V|version option output the package name and
the package version in the same format as autoconf-generated
configure scripts.
2014-12-09 Shiro Kawai <shiro@acm.org>
* libsrc/gauche/sequence.scm (break-list-by-sequence)
(break-list-by-sequence!): Added.
2014-12-07 Shiro Kawai <shiro@acm.org>
* ext/sparse/sparse.scm: Added missing generic ref and
call-with-iterator methods.
* libsrc/util/match.scm (in): Fixed a bug that emits incorrect
matching code. See addition in ext/util/test.scm for the
specific pattern to exhibit this bug.
2014-12-06 Shiro Kawai <shiro@acm.org>
* lib/gauche/dictionary.scm (dict-clear!): Added missing export.
2014-12-05 Shiro Kawai <shiro@acm.org>
* libsrc/gauche/sequence.scm (sequence-contains): Renamed for clarity.
(sequence->kmp-stepper): Expose KMP search element.
2014-12-01 Shiro Kawai <shiro@acm.org>
* src/gauche/vm.c (ScmIdentifier):
* src/compaux.scm (Scm_MakeIdentifier, Scm_OutermostIdentifier)
(Scm_UnwrapIdentifier, Scm_IdentifierGlobalBinding):
Allow nested identifier, that is, identifier to wrap another
identifier. Will be needed to support nested hygienic macros.
This changes the signature of Scm_MakeIdentifier, so
various files are touched to accomodate it.
2014-11-30 Shiro Kawai <shiro@acm.org>
* libsrc/gauche/sequence.scm (sequence-scan): Added.
2014-11-29 Shiro Kawai <shiro@acm.org>
* lib/data/trie.scm (trie-longest-match): Added.
2014-11-26 Shiro Kawai <shiro@acm.org>
* src/libcode.scm (compiled-code-push-info!): Added.
* src/compile.scm (pass5/lambda): Add 'definition debug info
to the compiled code created by $LAMBDA node.
(pass1/define): Attach original source code info to
the transformed lambda form.
* lib/gauche/procedure.scm (source-code, source-location): Added.
2014-11-25 Shiro Kawai <shiro@acm.org>
* src/error.c (Scm_Warn), src/libmisc.scm (warn): Allow suppressing
warning by environment variable GAUCHE_SUPPRESS_WARNING.
2014-11-18 Shiro Kawai <shiro@acm.org>
* gc/pthread_support.c (start_mark_threads): Experimantally added
code to set up signal masks for parallel marker threads. Eventually
this should be more generalized API and submitted to upstream,
but for the time being, let's see if this solves the "lost signal"
problem (the issue that delivered signal is discarded when it's
delivered to one of the marker threads instead of Gauche threads.)
2014-11-12 Shiro Kawai <shiro@acm.org>
* src/gauche/port.h (SCM_PORT_CASE_FOLDING): Renamed the macro name
from SCM_PORT_CASE_FOLD, which is the same name for the flag name
and could be confusing.
2014-11-11 Shiro Kawai <shiro@acm.org>
* src/main.c: Enable -fcase-fold in REPL mode, too (we only had it
work on scripts).
* src/port.c (Scm_GetPortCaseFolding, Scm_SetPortCaseFolding): APIs
to get/set port's case folding mode.
2014-11-10 Shiro Kawai <shiro@acm.org>
* lib/r7rs.scm (r7rs-import): Warn when a programmer say
(import (gauche)) in r7rs program. It's probably the first
attempt for her to use Gauche's builtin bindings in r7rs programs,
and it's better to guide her to (import (gauche base)).
* src/srfis.scm: For built-in srfi modules, make public symbols
exported so that r7rs programs can see them with (import (srfi N)).
From Gauche programs, those symbols are visible by default since
the module inherits the gauche module, so we haven't been careful
about exports. However, with r7rs programs we need to set them up
correctly.
2014-11-08 Shiro Kawai <shiro@acm.org>
* ext/tls: Upgraded to axTLS-1.5.0.
2014-11-07 Shiro Kawai <shiro@acm.org>
* src/gauche/char_utf_8.h (Scm__CharIsExtraWhiteSpace): Do not treat
U+180e as a whitespace char. It was changed from Zs to Cf in
Unicode 6.3.0. (NB: We also need update char_attr.[ch] for
char-general-category to reflect the change.)
2014-11-05 Shiro Kawai <shiro@acm.org>
* lib/gauche/test.scm (test*): Rewrote using er-macro so that
importing only 'test*' but not 'test' will still work.
* src/compile.scm (pass1/define): Rename toplevel identifier inserted
by a macro, to keep hygiene. RnRS does not specify this behavior
and implementations make different choices, but it seems that this
is the most straightforward way for Gauche to do the right thing.
Note that the code relying the (officially undefined) behavior,
that macro-injected toplevel binding appear in the macro calling
module, will break with this change.
2014-11-04 Shiro Kawai <shiro@acm.org>
* lib/gauche/test.scm (test-none-of): Added.
2014-11-02 Shiro Kawai <shiro@acm.org>
* src/compile.scm (%make-er-transormer),
lib/gauche/common-macros.scm (er-macro-transformer): Added to
give a shot.
* src/libmod.scm (global-identifier=?, free-identifier=?): Moved
from compile.scm
2014-10-30 Shiro Kawai <shiro@acm.org>
* src/number.c (Scm_MinMax): Return NaN if any of the arguments is NaN.
2014-10-28 Shiro Kawai <shiro@acm.org>
* lib/gauche/numerical.scm (encode-float): Added.
2014-10-27 Shiro Kawai <shiro@acm.org>
* lib/gauche/lazy.scm: Added linterweave.
2014-10-25 Shiro Kawai <shiro@acm.org>
* src/port.c: Experimentally allow access port information as
slots.
2014-10-23 Shiro Kawai <shiro@acm.org>
* src/libdict.scm (combine-hash-value): Expose internal COMBINE
to be used from other places. Not sure yet if this is general
enough, so for the time being this is EXPERIMENTAL.
2014-10-22 Shiro Kawai <shiro@acm.org>
* lib/data/trie.scm: Renamed util.trie -> data.trie.
2014-10-21 Shiro Kawai <shiro@acm.org>
* lib/data/heap.scm: Added find/remove!/delete! operations.
2014-10-20 Shiro Kawai <shiro@acm.org>
* lib/data/heap.scm: Using backing storage vector from element 0,
by offsetting the index. It is simpler in terms of API, and
in the long run it will win.
2014-10-19 Shiro Kawai <shiro@acm.org>
* lib/gauche/sortutil.scm (sorted?): Fixed a bug - the condition of
(sorted? (... x y ...)) should be (not (less? y x)) for every
consecutive pairs, instead of (less? x y). For example,
(sorted? '(1 1) <) should be #t.
* lib/gauche/sortutil.scm, lib/gauche/generic-sortutil.scm:
Accept comparators as well as less-than procedure.
2014-10-18 Shiro Kawai <shiro@acm.org>
* lib/gauche/vecutil.scm (vector-tabluate): Made it restart-safe.
(reverse-list->vector): Implement in core instead of srfi-43.
* test/vector.scm: Added.
2014-10-17 Shiro Kawai <shiro@acm.org>
* lib/gauche/computil.scm: Changed make-field-comparator to
make-key-comparator, for the consistency.
2014-10-16 Shiro Kawai <shiro@acm.org>
* lib/gauche/computil.scm: Added make-reverse-comparator,
make-field-comparator, make-car-comparator and make-cdr-comparator.
2014-10-13 Shiro Kawai <shiro@acm.org>
* lib/data/heap.scm: EXPERIMENTAL: Added binary min-max heap.
2014-10-11 Shiro Kawai <shiro@acm.org>
* ext/sparse/*: Renamed util.sparse -> data.sparse.
2014-10-10 Shiro Kawai <shiro@acm.org>
* src/libcmp.scm: Add srfi-114 primitive applicators as SUBR,
for the performance.
* lib/gauche/cgen/cise.scm: Make logand, logior and logxor n-ary.
2014-10-09 Shiro Kawai <shiro@acm.org>
* ext/sparse/sparse.scm: Allow make-sparse-table to take comparator.
Add sparse-table-comparator and sparse-vector-comparator to
conform new dictionary protocol.
2014-10-08 Shiro Kawai <shiro@acm.org>
* lib/gauche/dictionary.scm (dict-comparator): A new dictionary
protocol API to retrieve a comparator. It is useful to implement
generic meta-operations on dictionaries.
2014-10-07 Shiro Kawai <shiro@acm.org>
* src/libdict.scm (%make-tree-map),
lib/gauche/treeutil.scm (make-tree-map): Save a comparator
instead of closure in core->data field.
* src/libdict.scm (tree-map-comparator): Added to retrieve
the comparator.
2014-10-06 Shiro Kawai <shiro@acm.org>
* lib/gauche/treeutil.scm (make-tree-map): Allow to take a
comparator.
2014-10-05 Shiro Kawai <shiro@acm.org>
* src/hash.c, src/libdict.scm: Support general hash table
using comparators.
2014-10-04 Shiro Kawai <shiro@acm.org>
* src/libproc.scm (applicable?): Moved from lib/gauche/procedure.scm.
Needed in core in order to construct built-in comparators.
* src/libalpha.scm (case-lambda-info): Encapsulate interpretation
of case-lambda dispatch vector in this procedure, so that other
parts won't depend on the structure of the dispatch vector.
* lib/gauche/procedure.scm (disasm): Changed accordingly.
2014-10-03 Shiro Kawai <shiro@acm.org>
* src/libsys.scm (sys-sleep, sys-nanosleep): Changed to retry
sleep/nanosleep by default if it is interrupted by as signal.
They can be interrupted very often, for GC may use signals
to synchronize threads. We assume it's very unlikely that
there are programs that relies on the previous behavior,
but if you do need those procedures to return by signals,
give #t to the optional argument.
2014-10-02 Shiro Kawai <shiro@acm.org>
* src/cross-compile-ios.scm: A script to compile Gauche as an iOS
framework. This is kind of old---tested on 2013/07 with iOS6
and haven't updated since then. Just put it in repo for
a reference.
2014-10-01 Shiro Kawai <shiro@acm.org>
* lib/gauche/computil.scm : Added. Provides some basic comparators.
* src/autoload.scm: Autolaod computil.scm
2014-09-29 Shiro Kawai <shiro@acm.org>
* src/compare.c (Scm_Compare): Handle complex number ordering.
2014-09-28 Shiro Kawai <shiro@acm.org>
* src/compare.c (Scm_Compare): Implement ordering of different types,
according to srfi-114.
2014-09-27 Shiro Kawai <shiro@acm.org>
* src/compile.scm (define-syntax): Fix the case when toplevel
macro is inserted by another hygienic macro. We may need to
revisit interpretation of toplevel identifier renaming; see
the comment in pass1/define.
2014-09-26 Shiro Kawai <shiro@acm.org>
* src/compare.c (Scm_Compare), src/vector.c, src/symbol.c: Enhanced
domain of Scm_Compare to support srfi-114. Now booleans, lists,
symbols, vectors and uvectors can be compared each other.
* src/libcmp.scm (comparator-*): Added some srfi-114 comparator API.
2014-09-25 Shiro Kawai <shiro@acm.org>
* src/libvec.scm: Added uvector?
2014-09-24 Shiro Kawai <shiro@acm.org>
* ext/util/queue.scm, ext/data/queue.scm: util.queue -> data.queue.
2014-09-23 Shiro Kawai <shiro@acm.org>
* ext/math/mt-lib.stub: Merged to mt-random.scm
2014-09-22 Shiro Kawai <shiro@acm.org>
* ext/gauche/fcntlib.stub: Merged to fcntl.scm
2014-09-21 Shiro Kawai <shiro@acm.org>
* ext/zlib/zliblib.stub: Merged to zlib.scm
2014-09-20 Shiro Kawai <shiro@acm.org>
* lib/gauche/cgen/precomp.scm (without-precompiling): Added a special
directive to put the forms into *.sci file, without precompiling them.
If we want to cond-expand at load time, we can't precompile it.
* ext/termios/termiolib.stub: Merged to termios.scm
* ext/binary/binarylib.stub: Merged to io.scm
2014-09-19 Shiro Kawai <shiro@acm.org>
* examples/snake.scm: Added a sample of text.console.
2014-09-18 Shiro Kawai <shiro@acm.org>
* lib/text/console.scm: Added. Still unofficial & experimental.
2014-09-16 Shiro Kawai <shiro@acm.org>
* ext/termios/termios.scm (with-terminal-mode): Experimentally added.
2014-09-15 Shiro Kawai <shiro@acm.org>
* lib/gauche/interactive.scm (describe): Improve output of
(describe <generic>).
2014-09-13 Shiro Kawai <shiro@acm.org>
* src/gauche.h (SCM_FOREIGN_POINTER_REF): Calls Scm_ForeignPointerRef.
* src/class.c (Scm_ForeignPointerRef, Scm_ForeignPointerInvalidP)
(Scm_ForeignPointerInvalidate): Added. When the object pointed
by a foreign pointer became obsoleted (e.g. freed), you can mark
the foreign pointer "invalid", so that the subsequent dereference
of the pointer raises an error.
* src/libmisc.scm (foreign-pointer-invalid?, foreign-pointer-invalidate!):
Scheme interface for the above.
* ext/windows/console.stub (sys-set-screen-buffer-size): Fixed a bug.
* ext/vport/vport.scm (open-output-uvector):
Allow option to make the output buffer extendable.
(get-output-uvector): Added to enable retrieving the accumulated
result, needed when the buffer is extendable.
* lib/r7rs.scm (open-output-bytevector, get-output-bytevector):
Rewritten using above.
2014-09-12 Shiro Kawai <shiro@acm.org>
* lib/gauche/cgen/stub.scm (define-cptr): Fix a bug that passes
unboxer and boxer names in reverse (thanks to KOGURO Naoki).
* ext/uvector/uvector.scm (uvector-class-element-size)
(uvector-copy): Added.
2014-09-11 Shiro Kawai <shiro@acm.org>
* ext/uvector/uvector.scm (make-uvector): Added generic uvector
constructor.
* ext/template.configure: FIX: Added missing default_prefix setup.
* src/error.c (Scm_Raise), src/libexc.scm (raise),
src/vm.c (Scm_VMThrowException): The last fix of r7rs#raise
wasn't enough, for it invoked the second error with the same
exception handler as the first raise.
2014-09-10 Shiro Kawai <shiro@acm.org>
* lib/r7rs.scm (raise): Adjust r7rs#raise to be compatible with r7rs,
instead of using gauche#raise (srfi-19 compatible).
2014-09-09 Shiro Kawai <shiro@acm.org>
* lib/gauche/vecutil.scm (vector-for-each, vector-for-each-with-index):
Fix bugs when more than one vectors are given.
* lib/gauche/common-macros.scm (dotimes): Return #<undef> unless
the result clause is provided. It doesn't really matter, but better
to make it explicit that the return value is undefined.
2014-09-07 Shiro Kawai <shiro@acm.org>
* src/module.c (Scm_ImportModule): Fix a bug in dupe elimination
of imported modules. We should allow modules that have the same
origin, for they may have different qualifications; in such a case,
eliminating one will change the semantics.
2014-09-06 Shiro Kawai <shiro@acm.org>
* lib/Makefile.in: Don't forget to install gauche/base.scm.
* ext/util/queue.scm (dequeue-int): Clear the slots of dequeued
pair, to ensure weak-GC safety.
* lib/text/html-lite.scm: Support HTML5 elements and doctype
(patch from Takashi Fujita).
2014-09-04 Shiro Kawai <shiro@acm.org>
* src/number.c (Scm_StringToNumber): Allow '_' to be inserted between
digits when a number is explicitly prefixed. This is for the
readability, e.g. #b1101_1000_0001_1101 etc. We don't allow
unprefixed numbers, though, for the possible incompatibility
(e.g. 3_2 may be interpreted as a symbol.)
2014-09-03 Shiro Kawai <shiro@acm.org>
* lib/gauche/interactive.scm (describe): When object is char or integer,
print alternative representation / useful info if relevant.
2014-08-28 Shiro Kawai <shiro@acm.org>
* lib/gauche/cgen/precomp.scm (handle-define-syntax): Allow
Scheme-defined low-level macro transformer to be compiled
into *.c file, instead of emitting it to *.sci file.
* src/libmod.scm (%insert-syntax-binding): Added. Currently our
runtime don't distinguish toplevel value binding and syntax binding,
so %insert-binding can do both, but in future we may treat syntactic
binidng specially.
* src/compile.scm: Changed accordingly.
2014-08-24 Shiro Kawai <shiro@acm.org>
* src/gauche/macro.h -> src/gauche/priv/macroP.h: Moved macro
implementation details to private header. ScmSyntax and
ScmMacro should be treated as opaque objects. Various files
adjusted.
* src/macro.c (Scm_MakeMacro): Changed ScmMacro structure and
the signature of Scm_MakeMacro. Now ScmMacro is simply a wrapper
of macro transformer (Sexpr, Env -> Sexpr), with an optional
name. Technically this is an incompatible change, but we
expect nobody was directly using this interface.
We also change the way the macro expander is called; we pass
CENV, instead of a list frames, to the expander procedure.
This was never specified explicitly, and actually we had it wrong---
tye synrule expander expected frames, and the primitive expander
expected cenv. It happened to work because we hadn't used env
argument of primitive-expander yet.
* src/libeval.scm (macro-transformer): Added.
(call-macro-expander): Pass CENV to the third arg.
2014-08-23 Shiro Kawai <shiro@acm.org>
* src/macro.c (Scm_VMMacroExpand): Obsoleted. Implement it in
compile.c (%internal-macro-expand).
* src/libeval.scm (macroexpand, macroexpand-1): Changed accordingly.
2014-08-21 Shiro Kawai <shiro@acm.org>
* src/error.c (Scm_PrintDefaultErrorHeading),
src/libexc.scm (print-default-error-heading): Implement this in
Scheme for the better maintainability.
* src/libomega.scm (report-mixin-condition): Generalized handling
mixin conditions.
Note: The above two changes may be a dangerous move, which
can make it difficult to diagnose when we mess up then runtime
in a way that error reporting can't be carried out. Especially,
now we rely on working method dispatch to display mixin condition
messages. If this becomes an issue, we may replace the mixin
condition mechanism to more primitive ones, like manual dispatch.
* src/libexc.scm (<compile-error-mixin>),
src/compile.scm (compile): Handle compile error using mixin
condition.
2014-08-20 Shiro Kawai <shiro@acm.org>
* lib/gauche/exception.h, src/error.c (<load-condition-mixin>):
Added a mixin condition type to attach load context to
errors occurred during loading.
(Scm_PrintDefaultErrorHeading): Add load context information
when available.
(Scm_ExtractSimpleCondition): Added.
* src/libeval.scm (load-from-port): Intercept a thrown condition to
attach <load-condition-mixin>.
* lib/gauche/test.scm (<test-error>, test-check): Checks the
result condition considering compound conditions. In order to
use condition-has-type?, now <test-error> instance holds
the actual condition object.
* lib/gauche/condutil.scm, src/libomega.scm: Moved
definition of (slot-missing <condition-meta> <compound-condition>
<top>) from the former to the latter; Slots of compound conditions
may be referred without condutil being autoloaded.
2014-08-19 Shiro Kawai <shiro@acm.org>
* lib/binary/pack.scm (make-packer): Made cached? argument :optional
for the consistency with the doc.
2014-08-18 Shiro Kawai <shiro@acm.org>
* src/compile.scm (primitive-macro-transformer): Added experimentally;
the plan is to build all other macro system on top of this. See
if it's feasible.
(cenv-lookup-variable, cenv-lookup-syntax, env-lookup): Split
cenv-lookup into these APIs; mainly to avoid construction of
temporary cenv when we already have module and frames separately.
* src/libmod.scm (id->bound-gloc): Moved from compile.scm.
* src/macro.c (Scm_MakeMacroTransformer): Changed signature of
the transformer - now it takes form and macro-use environment.
2014-08-16 Shiro Kawai <shiro@acm.org>
* src/compile.scm (ensure-identifier): Properly capture the environment
into the created identifier.
(%bind-inline-er-transformer): Fix incorrect initialization of
cenv.
(%attach-inline-er-transformer): Make compare closure work.
(free-identifier=?): Added.
2014-08-14 Shiro Kawai <shiro@acm.org>
* src/system.c (Scm_AvailableProcessors),
src/syslib.scm (sys-available-processors): Added to query # of
available processors.
2014-08-13 Shiro Kawai <shiro@acm.org>
* lib/gauche/vm/debugger.scm (debug-funcall), src/read.c (#?,):
Experimentally added a new debug form, #?,(proc arg ...). Unlike
debug-print (#?=), this displays the value of arg ....
2014-08-11 Shiro Kawai <shiro@acm.org>
* src/load.c, src/libeval.scm (load-from-port): Rewrote load-from-port
in Scheme. Scm_VMLoadFromPort is no longer used. An internal
procedure Scm__RecordLoadStart is also obsoleted.
Also dropped LOAD_MAIN_SCRIPT flag. This flag is introduced on
2011-01-02, but has never been used, and never been officially
announced.
2014-08-10 Shiro Kawai <shiro@acm.org>
* src/gauche.h etc.: Removed pre-0.9 compatibility macro definitions.
It's been almost 5 years since 0.9 release and it's about time.
The compatibility routines (*Compat()) are kept in *.c file so
that the old compiled binaries keep working until 1.0 release.
However, newly compiled binaries should adopt 0.9 API.
* libsrc/util/match.c: Fixed a bug that doesn't handle match
expressions generated by hygienic macros. The `quote' in
patterns may become an identifier in the macro output.
2014-08-09 Shiro Kawai <shiro@acm.org>
* src/symbol.c: Enabled support of symbol-keyword unification,
though it's off by default for the backward compatibility.
Setting environment variable GAUCHE_KEYWORD_IS_SYMBOL turns on
the feature. At some point in future we flip the default,
so the feature will be on by default, and setting enviornment
variable GAUCHE_KEYWORD_DISJOINT turns off.
2014-08-07 Shiro Kawai <shiro@acm.org>
* src/write.c (Scm_Write): Avoid using srfi-38 notation if
(display <string>) is called within write-shared. It doesn't
contribute readability at all (since you can't know what the
label refers), and sometimes interferes with user-defined
object writer.
2014-08-04 Shiro Kawai <shiro@acm.org>
* ext/termios/termiolib.stub (sys-termios-copy): Added.
2014-08-02 Shiro Kawai <shiro@acm.org>
* ext/uvector/*, src/vector.c: Restructured the sources.
Now we name the resulting DSO as gauche--uvector.so, consistent
to other extension modules. IMPORTANT: This means we no longer
allow other extension modules to link with -lgauche-uvector.
We used to need it for extension modules to access uvector features,
but now the basic uvector support is in the core and we no longer
need it. Besides, building one SO for both dlopen and -l linking
doesn't work on OSX. Some legacy extension modules may still
referring -lgauche-uvector; they should be updated.
Since gauche--uvector.so is now purely accessed through Scheme,
it doesn't make sense to provide full line of C API; so some of
them are folded into define-cproc.
The uvector reader is moved to src/vector.c as well, so that
reading uvector literals won't cause autoloading gauche.uvector.
2014-07-31 Shiro Kawai <shiro@acm.org>
* ext/uvector/uvlib.stub.tmpl (string->[us]32vector!): Added.
* src/load.c, src/gauche/load.h: Turn dlobj record to ScmObj. This
is for better introspection, and for preparation of exposing dlopen
to Scheme.
2014-07-29 Shiro Kawai <shiro@acm.org>
* src/srfis.scm: Consolidate info of supporting srfis in one file,
to generate files that need to reflect the info.
* ext/srfi/generate-srfi.scm: Superseded by src/srfis.scm
2014-07-28 Shiro Kawai <shiro@acm.org>
* src/libmisc.scm (box etc.): srfi-111 support. This is merely to
expose internal box object to the Scheme world. We still use
srfi-111 namespace, though.
* src/box.c (box_compare): compare contents.
2014-07-27 Shiro Kawai <shiro@acm.org>
* src/libomega.scm, src/load.c: Mark all built-in modules as provided,
so that (use <built-in-module>) won't complain. This used to be
done in load.c, but we kept the module list separately which had
gone out-of-sync.
2014-07-24 Shiro Kawai <shiro@acm.org>
* lib/gauche/configure.scm (parse-command-line-arguments): Fix
handling --enable-*, --disable-*, --with-* and --without-* options.
2014-07-23 Shiro Kawai <shiro@acm.org>
* lib/gauche/base.scm: Split gauche.base form r7rs.scm, for it may
be used from Gauche code by (use gauche.base); see the document
for the use case.
2014-07-22 Shiro Kawai <shiro@acm.org>
* src/module.c (search_binding): Fixed a bug - when a module exports
an inherited binding with renaming, it wasn't searched properly.
Another bug fix - if phantom binding is exported with renaming,
and then renamed on import, this bug sufraces.
2014-07-20 Shiro Kawai <shiro@acm.org>
* lib/gauche/configure (cf-make-gpd): A cf api to generate gpd file.
(cf-echo): Fix a bug that drops last two arg if the output is not
redirected (thanks to KOGURO Naoki). Also made it appear in
config.log.
* ext/template.configure: Added call to cf-make-gpd.
* ext/template.Makefile.in (maintainer-clean),
src/gauche-package.in (generate): Do not delete
configure in maintainer-clean if we create skeletons to use
gauche.configure.
2014-07-19 Shiro Kawai <shiro@acm.org>
* release 0.9.4
* lib/gauche/configure.scm (check-for-program): Fixed a bug that refer
to the variable 'paths' that's being defined, i.e.
(define paths (... paths ...)).
2014-07-18 Shiro Kawai <shiro@acm.org>
* src/libio.scm, lib/r7rs.scm (read-string): Support R7RS-compatible
read-string in the core.
* ext/text/parse.scm (read-string): Redefined on top of built-in
read-string.
2014-07-16 Shiro Kawai <shiro@acm.org>
* src/macro.c (compile_rules): Allow syntax-rules to have no rules,
as the spec permits.
* lib/scheme/*.scm: Placed dummy modules to use R7RS stdlibs
from Gauche
2014-07-14 Shiro Kawai <shiro@acm.org>
* lib/r7rs.scm, src/libvec.scm: Moved vector->string and string->vector
from r7rs to core, for less confusion.
2014-06-25 Shiro Kawai <shiro@acm.org>
* src/read.c (read_internal): In strict-r7 reader mode, read :foo
as a symbol. This would be unnecessary once we make keywords
a subtype of symbols, but for now, it would help using third-party
r7rs libraries.
2014-06-22 Shiro Kawai <shiro@acm.org>
* ext/windows/console.stub (sys-fill-console-output-attribute)
(sys-fill-console-ouptut-character, sys-flush-console-input-buffer):
Added.
(<win:input-record>): Made key.virtural-key-code return
VirtualKeyCode, and let key.virtual-scan-code return
VirtualScanCode.
(sys-read-console-input): Fix.
Patch from https://github.com/Hamayama.
2014-06-21 Shiro Kawai <shiro@acm.org>
* src/read.c: Split reader-lexical-mode from <read-context> and made
it an individual parameter. The mode can be changed during Scm_Read()
if we encoundter #!r7rs etc., so it doesn't work to carry the info
inside read-context.
* src/load.c, src/libio.scm: Changed accordingly.
2014-06-20 Shiro Kawai <shiro@acm.org>
* lib/srfi-42.scm: Incorporated bug fixes in srfi-42 reference
implementation.
2014-06-18 Shiro Kawai <shiro@acm.org>
* gc/*: Updated to gc-7.4.2 (libatomic_ops stays 7.4.2)
2014-06-05 Shiro Kawai <shiro@acm.org>
* src/number.c (Scm_GetDouble): exact->inexact conversion didn't
work in denormalized range.
(Scm_EncodeFlonum): Added as an inverse of Scm_DecodeFlonum;
not made public in the header yet.
2014-05-25 Shiro Kawai <shiro@acm.org>
* configure.ac: Add -static-libgcc flag when building DLLs on MinGW,
in ordre to avoid dependency on libgcc_s_dw2-1.dll.
2014-05-21 Shiro Kawai <shiro@acm.org>
* gc/*: Updated to gc-7.4.0 and libatomic_ops-7.4.2
2014-05-16 Shiro Kawai <shiro@acm.org>
* src/gauche.h, src/string.c (SCM_STRDUP, SCM_STRDUP_PARTIAL): Added
these, for I felt I wrote SCM_MALLOC+memcpy too many times.
* src/dl_win.c, src/port.c, src/system.c: Changed accordingly.
2014-05-15 Shiro Kawai <shiro@acm.org>
* src/system.c (Scm_GetEnv): Provide a wrapper so that we can mutex
getenv/putenv properly.
2014-05-09 Shiro Kawai <shiro@acm.org>
* src/win-compat.c (mbs2wcs, wcs2mbs): Allow libgauche version of
those functions to choose allocator; we need to malloc (instead
of GC_alloc) if we pass the resulting string to OS.
2014-05-07 Shiro Kawai <shiro@acm.org>
* src/main.c (main): Changed handling of command-line args on Windows
so that it can get wide characters properly. Based on a patch
from SAITO Atsushi.
2014-05-05 Shiro Kawai <shiro@acm.org>
* ext/text/unicode.scm (%foldcase): Fixed string-foldcase behavior.
See the discussion in R7RS mailing list:
http://lists.scheme-reports.org/pipermail/scheme-reports/2014-May/004055.html
* test/r7rs-tests.scm: The test for string-foldcase was incorrect.
Fixed along above.
2014-05-01 Shiro Kawai <shiro@acm.org>
* ext/uvector/uvlib.stub.tmpl (u8vector->string, s8vector->string):
Avoid copying the content when the source vector is immutable and
certain conditions are met. See the comment in bytevector->string
for the details.
2014-04-29 Shiro Kawai <shiro@acm.org>
* ext/uvector/uvlib.stub.tmpl (string->u8vector, string->s8vector):
Added optional immutable? flag; if #t, the result vector becomes
immutable, and we avoid copying the string body.
2014-04-28 Shiro Kawai <shiro@acm.org>
* lib/gauche/common-macros.scm (unwind-protect): Fixed the bug that
cleanup clause wasn't called when applications exit within the body.
2014-04-27 Shiro Kawai <shiro@acm.org>
* src/libio.scm (close-port, call-with-port): Support these r7rs procs
natively. They're useful. (Actually, we didn't have call-with-port
even in r7rs module; it was an oversight.)
2014-04-17 Shiro Kawai <shiro@acm.org>
* lib/rfc/json.scm (%unicode, print-string): Properly support
unicode surrogate pairs.
