* 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.
scm_struct_i_n_words to get the number of fields, not
-scm_struct_n_extra_words.
On the route to fancier struct printing:
* struct.c (scm_print_struct): New function to print a structure.
Include "genio.h" to support it. This function doesn't do
anything interesting right now, but I think it should be here
anyway.
* struct.h: Include "print.h" and add prototype for
scm_print_struct.
* print.c (scm_iprin1): Call scm_print_struct instead of trying to
print structures ourself.
required by the tagging system.
* struct.c (alloc_struct): New function.
(scm_make_struct, scm_make_vtable_vtable): Call it.
* struct.h (scm_struct_n_extra_words): Bump to 3.
(scm_struct_i_ptr): New "field".
* gc.c (scm_gc_sweep): When we need to free the data, use the
information stored by alloc_struct to find the beginning of the
block allocated to the structure, so we can free it.
scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
Lord's implementation of structs, allowing for tail arrays as
described in the manual. Also fixed some bugs. (Both the interface
and the implementation should be improved.)
main #include path; put most of them in a subdirectory called
'libguile'. This avoids naming conflicts between Guile header
files and system header files (of which there were a few).
* Makefile.in (pkgincludedir): Deleted.
(innerincludedir): New variable; this and $(includedir) are enough.
(INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
(installed_h_files): Divide this up. Now this variable lists
those header files which should go into $(includedir) (i.e. appear
directly in the #include path), and ...
(inner_h_files): ... this new variable says which files appear in
a subdirectory, and are referred to as <libguile/mumble.h>.
(h_files): List them both.
(install): Create innerincludedir, not pkgincludedir. Put
the installed_h_files and inner_h_files in their proper places.
(uninstall): Corresponding changes.
