* print.h (SCM_PRINT_STATE_P): Removed SCM_NIMP test. (NIMP
macros should by convention not test for NIMPness.)
(SCM_COERCE_OPORT): Adjust indentation.
* print.c (scm_valid_oport_value_p): Adjusted indentation; Added
SCM_NIMP test before SCM_PRINT_STATE_P.
* struct.c, struct.h, gc.c: Renamed:
scm_struct_i_layout --> scm_vtable_index_layout
scm_struct_i_vcell --> scm_vtable_index_vcell
scm_struct_i_vtable --> scm_vtable_index_vtable
scm_struct_i_printer --> scm_vtable_index_printer
scm_struct_i_vtable_offset --> scm_vtable_offset_user
* struct.c (scm_print_struct): Use new printer slot; Default
printing: Also output hex code of vtable so that type identity
will be indicated as well.
(scm_init_struct): Updated required_vtable_fields to "pruosrpw";
Removed struct_printer_var; Removed struct-vtable-offset;
(vtable-index-layout, vtable-index-vtable, vtable-index-printer,
vtable-offset-user): New constants.
* struct.h (scm_struct_i_vtable_offset): Bumped from 3 to 4.
(scm_struct_i_printer, SCM_STRUCT_PRINTER): New slot in vtables.
If this slot contains a procedure, use that to print structures of
the type represented by this vtable.
* print.c (scm_iprin1): Don't print arguments of macro
transformers. (They are always: exp env.); Bugfix: Unmemoize
transformer source with correct environment.
there is now only one catch.
(cwdr_outer_body): Removed.
(cwdr_handler): New function.
(scm_internal_cwdr): New function to perform the function of cwdr
but take args that are more useful to C code. Also, the handler
is now invoked *outside* of the new dynamic root, like the docs
say. We no longer have to catch absolutely all errors, the caller
is responsible for using a handler that does not throw, if he
wants that.
(cwdr): Reimplemented in terms of scm_internal_cwdr.
* root.h (scm_internal_cwdr): New prototype.
* root.c (USE_STACKJMPBUF): New define to activate a stack-based
allocation of the jumpbuf of a root continuation. The changes
below are controlled by it. They are now deactivated.
(scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
the JMPBUF of the scm_rootcont to NULL before returning.
(struct scm_print_state) [revealed]: New field.
(scm_print_state_vtable): Make visible to the outside world for
type checking purposes.
(scm_valid_oport_value_p): New prototype.
* print.c (scm_valid_oport_value_p): New function to check whether
a certain value is acceptable as a port argument.
(scm_print_state_vtable): New variable.
(scm_free_print_state): Set `revealed' field to false.
(scm_iprin1): Call user supplied closure printer with
scm_printer_apply. Print in the traditional way when there isn't
one or when it returns #f.
(scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
Accept a port/print-state pair in addition to just a port.
(scm_prin1): Don't return the print_state to the pool when it has
been `revealed'.
(scm_printer_apply): Set `revealed' field of print_state to true.
(scm_init_print): Set scm_print_state_vtable.
(print_state_fluid, print_state_fluid_num): Removed.
when they are non-NULL.
(scm_gc_mark): Likewise, mark only when non-NULL.
* gc.c (scm_done_malloc): New function.
gc.h (scm_done_malloc): New prototype.
arguments, don't set the car of (command-line) to scm_usage_name,
the prettified name of the guile executable; give it the full
path, the way shells usually handle $0.
makefile variable as a build parameter called LIBS. The
build-guile program will use this, for the time being.
* Makefile.in: Regenerated.
* Makefile.in: Regenerated with automake 1.2a.
`display-error' and `display-backtrace' so that error reporting
won't get into infinite loops if an error occurs during displaying
of the error. This can very easily happen with user supplied
print call-back routines.
Added #include "objects.h"
* eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
Add #include "feature.h".
* ports.h (SCM_EOF_OBJECT_P): New macro predicate.
This test is needed at many places in the code and should be
abstracted. (Motivated by the need of this test in libguiletk.)
* ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
(scm_eval_string), load.c (scm_primitive_load,
scm_read_and_eval_x), gh_eval.c (gh_eval_str):
Use SCM_EOF_OBJECT_P.
* eval.c (scm_init_eval): Add feature `delay'.
* 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.
procedures;
(prinmacro): Removed. The code has been moved/merged into print.c
in order to decrease code redundancy. We want macros to print in
a way equivalent to procedures, and it would be silly to duplicate
the required code. (We don't want to maintain two places.)
(macrosmob): Print field is now a NULL pointer.
* eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
scm_macro_transformer): New prototypes.
(scm_tc16_macro): Declared.
* * print.c (scm_iprin1): Added code for printing of macros. Macros
are now printed in a way equivalent to procedures.
gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
gh_equal_p): Use SCM_NFALSEP, instead of testing against
SCM_BOOL_T. Any non-false value is true.
scm_gensym): Added prototypes.
* symbols.c (scm_gensym): New function. This will speed up
certain types of applications (such as macro systems) which
generate lots of symbols.
