custom tc7 type. This will make it easier to support R5RS
multiple value continuations, without the use of a Scheme-level
wrapper.
* continuations.c (scm_tc16_continuation, continuation_mark,
continuation_free, continuation_print, continuation_apply):
new SMOB support.
(scm_make_continuation): new procedure, replaces scm_make_cont
with a different interface.
(copy_stack_and_call, scm_dynthrow, scm_init_continuations): rewritten.
(CHEAP_CONTINUATIONS): removed non-working code completely.
(scm_call_continuation): removed.
* continuations.h (struct scm_contregs): add num_stack_items and
stack fields. previously stack was stored following this struct:
use a tail array instead.
(SCM_CONTINUATIONP): new macro.
(SCM_CONTINUATION_LENGTH, SCM_SET_CONTINUATION_LENGTH):
rewritten.
(SCM_SET_CONTREGS): removed.
* tags.h: removed scm_tc7_contin (was tag 61).
* debug.c, gc.c, hash.c, print.c, procprop.c, procs.c:
removed scm_tc7_contin support.
* eval.c: use scm_make_continuation instead of scm_make_cont.
don't set jump buffers here. remove scm_tc7_contin support.
* init.c, root.c: create SMOB continuation for rootcont instead
of scm_tc7_contin. call scm_init_continuations before
scm_init_root.
* root.c: remove support for static jmpbuf. It's not used by
default and I broke it. create SMOB continuation for rootcont.
* stacks.c: use SCM_CONTINUATIONP.
* Fix some string/symbol output problems with regards to substrings.
* Fix error output to prefer procedure name parameters over stack data.
* Use SCM_(SET_)?FILENAME where appropriate.
* Prefer calling scm_remember over scm_protect/unprotect_object calls.
(scm_init_struct): First arg to scm_make_vtable_vtable should be a
string, not a symbol. (`make-vtable-vtable' needs to append this
string to another string and then pass it through
`make-struct-layout'.)
and we don't want that.
(INCLUDES): Removed all -I options except for the root source
directory and the root build directory.
* *.*: Change includes so that they always use the "prefixes"
libguile/, qt/, guile-readline/, or libltdl/.
(Thanks to Tim Mooney.)
eliminating some warnings.
* unif.c, strports.c, print.c, options.c: Fix some warnings on
mis-use of SCM/long
* gc.c, gc.h: Added scm_return_first_int(), and added comment re:
what the scm_return_first* functions do.
name for a Scheme object (now a void*), and SCM as 32 bit word for
storing tags and immediates (now a long int). Introduced
SCM_ASWORD and SCM_ASSCM for conversion. Fixed various dubious
code in the process: arbiter.c (use macros), unif.c (scm_array_p),
displaying the expected type. Use SCM_LISTn in a couple places
instead of scm_cons-ing by hand.
* __scm.h: Added SCM_ASSERT_TYPE macro.
* validate.h, scm_validate.h: Added the former, as a renamed
version of the latter with SCM_ASSERT_TYPE used in
SCM_MAKE_VALIDATE (instead of just SCM_ASSERT)
* Makefile.am: Rename scm_validate.h to validate.h.
* *.c, *.h: Include validate.h, not scm_validate.h (old name's
prefix was superfluous).
added append docs from R4RS.
* strings.c: Docstring typo fix, + eliminate unneeded IMP tests.
Thanks Dirk Hermann!
* chars.h: Provide SCM_CHARP, SCM_CHAR, SCM_MAKE_CHAR and
deprecate SCM_ICHRP, SCM_ICHR, SCM_MAKICHR. Thanks Dirk Hermann!
* *.h, *.c: Use SCM_CHARP, SCM_CHAR, SCM_MAKE_CHAR throughout.
Drop use of SCM_P for function prototypes... assume an ANSI C
compiler. Thanks Dirk Hermann!
regex-posix.c, scmsigs.c, stime.c, strings.c, variable.c, stime.c,
strings.c, variable.c: Added lots of documentation, cleaned up
some existing documentation. Occasionally changed formal params
to match docs. Also folded an #ifdef into the inners of a
primitive instead of having two copies of the primitive
(`get-internal-real-time', from stime.c)
net_db.c, sort.c, stacks.c, unif.c: Use SCM_WTA, SCM_MISC_ERROR
where possible.
* symbols.c (scm_sysintern0): Fixed the function name in a
scm_misc_error invocation.
* print.c (scm_simple_format): Do not need SCM_COERCE_SUBSTR, and
use scm_return_first to ward off latent GC bug that Mikael caught.
* async.c: Use SCM_VALIDATE_ASYNC_COPY one place where it wasn't
used before but should've been.
strop.c: Use SCM_VALIDATE_ICHR, SCM_VALIDATE_ICHR_COPY instead of
SCM_VALIDATE_CHAR, SCM_VALIDATE_CHAR_COPY. Change made for
consistency with the other macros dealing with immediate
characters. (Similar to INT -> INUM change a week or so ago).
net_db.c, read.c, socket.c: Update error messages to use ~A for
%s, ~S for %S to work with new `simple-format' format and be
standardized better.
* print.h, print.c (scm_simple_format): Added `simple-format'
primitive. It's the old scm_display_error, with ARGS now a rest
parameter, and the destination first instead of last (and a couple
new capabilities inspired by `format' -- #t as destination means
current-output-port, #f means return the formatted text as a
string.
* gh.h, gh_data.c, ports.h, ports.c: Added some missing const specifications.
* backtrace.c (scm_display_error_message): Rewrote to use
scm_simple_format() procedure.
* __scm.h: Added commented-out #define of GUILE_DEBUG_FREELIST
posix.c: Eliminated a bunch of SCM_NIMP(..)s that are now
redundant with the safer macros. Patch from Dirk Hermann applied
by hand. Thanks Dirk!
* scm_validate.h: Added SCM_VALIDATE_VECTOR_OR_DVECTOR for some
uses in random.c.
* ramap.c: whitespace change.
* scm_validate.h: Added SCM_VALIDATE_THREAD.
* *.c: Remove SCM_NIMP(X) when it is an extraneous pre-test given
that SCM_FOOP macros all now include SCM_NIMP in their expansion.
This simplifies lots of code, making it far more readable.
* guile-doc-snarf.awk.in: Added.
* ports.c (s_scm_pt_member): Fixed validation.
* guile-doc-snarf.in (filename): Use basename in order to strip
away path.
* debug.c (scm_make_iloc, s_scm_proc_to_mem): Added missing
semicolon.
(scm_memcons, scm_memcons, mem_to_proc): Renamed function name
strings to new form.
* backtrace.c (set_print_params_x): Fixed GUILE_PROC macro.
* tags.h (SCM_UNBOUND): New iflag which is needed for some time to
mark the unboundness of a GOOPS slot. (Added now in order to
correct a oversight. Should probably be removed again and
replaced with SCM_UNDEFINED when the corresponding code in GOOPS
is rewritten.)
* print.c (scm_isymnames): Added printed representation for
SCM_UNBOUND.
* eval.c (SCM_CEVAL): Bugfix: Added check for unbound slot in
SCM_IM_SLOT_REF.
