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.
initialization of c[ad]+r functions.
* Remove structs scm_subr and scm_dsubr and access the function cell words
directly instead of casting a cell to a C struct.
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.)
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).
* 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_PROC1. Build guile-procedures.txt, and add that file to
pkgdata_DATA.
* load.c: Added `pkgdata-dir', `site-dir', `library-dir'
primitives.
* guile-doc-snarf.awk: Drop trailing space when no arguments:
e.g., "(foo )" is now "(foo)".
* *.c: moved all the documentation for primitives from
guile-doc/ref/{appendices,posix,scheme}.texi into the source code.
This leaves about half of the primitives undocumented. Also, all
the markup is currently still texinfo. I don't have a problem
with texinfo per se, but the markup is not very descriptive or
accurate.
function headers and argument checking. Switched SCM_PROC,
SCM_PROC1 macros to be GUILE_PROC, GUILE_PROC1 (may change names
later, but was useful to keep old versions around while migrate)
that has docstrings and argument lists embedded in the GUILE_PROC
macro invocations that expand into a function header. Use lots of
new SCM_VALIDATE_* macros to simplify error checking and reduce
tons of redundancy. This is very similar to what I did for Scwm.
Note that none of the extraction of the docstrings, nor software
engineering checks of Scwm is yet added to Guile. I'll work on
that tomorrow, I expect.
* Makefile.am: Added scm_validate.h to modinclude_HEADERS.
* chars.c: Added docstrings for the primitives defined in here.
* snarf.h: Added GUILE_PROC, GUILE_PROC1. Added
SCM_REGISTER_PROC to be like old SCM_PROC, though old SCM_PROC
still remains for now. Changed naming convention for the s_foo
string name of the primitive to be s_scm_foo for ease of use with
the macro.
* scm_validate.h: Lots of new SCM_VALIDATE macros to simplify
argument checking through guile. Maybe some of these should be
folded into the header file for the types they check, but for now
it was easiest to just stick them all in one place.
associated with subrs.
(SCM_SUBRNUM, SCM_SUBR_ENTRY, SCM_SUBR_GENERIC, SCM_SUBR_PROPS,
SCM_SUBR_DOC): New macros.
(scm_subr_table): New variable.
(scm_mark_subr_table): New function.
* init.c (scm_boot_guile_1): Call scm_init_subr_table.
* gc.c (scm_gc_mark): Don't mark subr names here.
(scm_igc): Call scm_mark_subr_table.
* snarf.h (SCM_GPROC, SCM_GPROC1): New macros.
* procs.c, procs.h (scm_subr_p): New function (used internally).
* gsubr.c, gsubr.h (scm_make_gsubr_with_generic): New function.
* objects.c, objects.h (scm_primitive_generic): New class.
* objects.h (SCM_CMETHOD_CODE, SCM_CMETHOD_ENV): New macros.
* print.c (scm_iprin1): Print primitive-generics.
* __scm.h (SCM_WTA_DISPATCH_1, SCM_GASSERT1,
SCM_WTA_DISPATCH_2, SCM_GASSERT2): New macros.
* eval.c (SCM_CEVAL, SCM_APPLY): Replace scm_wta -->
SCM_WTA_DISPATCH_1 for scm_cxr's (unary floating point
primitives). NOTE: This means that it is now *required* to use
SCM_GPROC1 when creating float scm_cxr's (float scm_cxr's is an
obscured representation that will be removed in the future anyway,
so backward compatibility is no problem here).
* numbers.c: Converted most numeric primitives (all but bit
comparison operations and bit operations) to dispatch on generic
if args don't match.
* eval.c, eval.h (scm_eval_body): New function.
* objects.c (scm_call_generic_0, scm_call_generic_1,
scm_call_generic_2, scm_call_generic_3, scm_apply_generic): New
functions.
* eval.c (SCM_CEVAL): Apply the cmethod directly after having
called scm_memoize_method instead of doing a second lookup.
* objects.h (scm_memoize_method): Now returns the memoized cmethod.
* procs.c (scm_make_subr_opt): Use scm_sysintern0 instead of
scm_sysintern so that the binding connected with the subr name
isn't cleared when we give set = 0.
* gsubr.c: New global symbol scm_i_inner_name.
* debug.c (scm_procedure_name): Try procedure property
`inner-name' if `name' fails.
* print.c (scm_iprin1): Use scm_macro_name.
* eval.c (scm_m_define): Give names to macros as well; Only the
first top-level definition gives a procedure/macro a name.
Otherwise confusing names can turn up in backtraces.
(SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
`name'; Give names to macros as well.
* procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
(scm_macro_transformer): Use SCM_CLOSUREP instead of
scm_closure_p.
