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.
options.c): Rename RECKLESS -> SCM_RECKLESS, CAUTIOUS ->
SCM_CAUTIOUS; this way, 1) there's only one version of each flag
to define (we used to have both RECKLESS and SCM_RECKLESS), and 2)
if we want to use them in a header file some day, we can. (Thanks
to Michael Livshin.)
warning.
* eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
to avoid compiler warnings.
* dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
* 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.
<shouman@zianet.com>: "The switch in scm_gsubr_apply that
dispatches on the number of actual args has a default case
reporting an internal error. This is a vestige from a version
that mallocated a SCM vector to hold the arguments. In the
current version this check is too late: if it ever happens we will
have already overstepped the bounds of the array.
Also, the patch [...] adds a check for too many actual arguments."
mdj: Removed check for "internal programming error".

mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
(Among other things, this change makes it easier to build Guile
with certain compilers which have problems with casted lvalues.)
(scm_m_define): Record names of all kinds of procedure
objects. (Earlier, only closures were recorded.)
* gsubr.c: Added global scm_i_name. Added #include "procprop.h".
(scm_make_gsubr): Record names of compiled closures.
integer (assuming for now accepting an integer is a good thing).
* error.c, fports.c: replace use of %S in lgh_error args with %s.
%S will be used instead for write'ing arguments.
* unif.c (scm_transpose_array): change arguments in the SCM_WNA
asserts. fix a few other asserts.
(scm_aind, scm_enclose_array, scm_array_in_bounds_p,
scm_uniform_vector_ref, scm_array_set_x,
scm_dimensions_to_unform_array): change args in
SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
scm_substring_fill_x): likewise.
gsubr.c (scm_gsubr_apply): likewise.
eval.c (SCM_APPLY): likewise.
* eval.c (4 places): replace scm_everr with lgh_error or
scm_wrong_num_args.
* error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
scm_memory_error): new procedures.
* scm_everr: deleted. can use scm_wta, dropping first two args.
scm_error: convert NULL subr to SCM_BOOL_F.
* __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
SCM_ARGERR.
* stackchk.c (scm_report_stack_overflow): use lgh_error instead
of scm_wta.
* error.c, error.h: new error keys: scm_arg_type_key,
scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
scm_misc_error_key.
scm_wta: reimplement using lgh_error instead of scm_everr.
