* boot-9.scm (struct-layout): Use `vtable-index-layout' instead of
`0'.
1997-10-02 Mikael Djurfeldt <mdj@nada.kth.se>
* boot-9.scm (struct-printer, make-struct-printer,
set-struct-printer-in-vtable!, *struct-printer*): Removed.
(record-type-vtable, make-record-type): Don't use make-struct-printer.
(record-type-vtable): User fields "prpr" (printer is no longer a
user field).
(record-type-name, record-type-fields): Decreased slot index by
one; Use `vtable-offset-user'.
* 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.
* boot-9.scm: Split off modules into separate, autoloadable files.
This reduces startup time from 10.5s to 5.5s (user cpu).
* calling.scm, common-list.scm, ls.scm, q.scm, runq.scm,
string-fun.scm: New files, containing stuff that used to be in
boot-9.scm.
* Makefile.am (ice9_sources): List new files here, for
distribution and installation.
* Makefile.in: Regenerated.
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.
separate-fields-after-char, separate-fields-before-char): Call
continuation function, RET, as advertised: with each separated
field a separate argument.
* 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.
