bdc88419bd * procs.c: #include "objects.h" 
(scm_procedure_p): Return #t also on structs which are operators.
 1998-11-21 17:01:48 +00:00
Mikael Djurfeldt
af3645c52b * objects.c (scm_init_objects): Renamed <standard-metaclass>, 
<operator-metaclass> and <entity-class> to <standard-class>,
<operator-class> and <entity> in order to conform with STKlos
naming conventions.

9b07e212d5 * eval.c (SCM_CEVAL): Jump to badfun if trying to apply a struct 
which isn't an operator.
(SCM_APPLY): Ditto, but jump to badproc.

b325a6c8ac * evalext.c (scm_definedp): Removed check for isyms; Added a 
second optional argument: It is now possible to supply an
evaluation environment in which to look for the symbol.

aa00bd1e54 * eval.c (SCM_CEVAL): Allow structs implanted in code. 
Previously, structs implanted in code were interpreted as forms
the operator of which was a gloc.  We solve this by checking for
the zero in the emulated vcell in the struct vtable.  Since
implanted structs always will look like forms with a gloc
operator, execution will only be slowed down by maximally one
extra test-and-branch per application.

b322f09ab8 * coop.c (coop_condition_variable_wait): Removed 
(coop_condition_variable_wait_mutex): Folded logic of
coop_mutex_unlock into coop_condition_variable_wait_mutex to
prevent condvar signal lossage.  Previously, another thread could
start to run after unlocking the mutex but before putting the
current thread on the wait queue.  If that thread then would
signal the first, the signal would be lost.  (Thanks to Christian
Lynbech.)
 1998-11-19 08:15:22 +00:00

3b2ee8bcdf * readline.c (scm_init_readline): Set 
rl_basic_word_break_characters.  (Thanks to Ian Grant.)
 1998-11-19 04:48:50 +00:00
Mikael Djurfeldt
224822be69 * eval.c (SCM_CEVAL): Added missing case for cclo. (Thanks to 
Christian Lynbech.)
 1998-11-17 08:03:18 +00:00
Mikael Djurfeldt
036737fce8 * objects.c (scm_i_make_class_object): Renamed from 
make_class_object; exported; error checking moved to
scm_make_class_object and scm_make_subclass_object.
(scm_make_class_object, scm_make_subclass_object): Use
scm_i_make_class_object.
(scm_make_subclass_object): Let the subclass have same metaclass
as the superclass.

a6e350ddef * debug.c (scm_debug_options): Bugfix: Set the value of 
scm_stack_checking_enabled_p after setting debug options;
#include "stackchk.h".  (Thanks to Richard Polton.)

067affe319 * eval.c (scm_copy_tree): Copy source properties if existent. 1998-11-10 14:17:24 +00:00
Mikael Djurfeldt
cb412265a7 * debug.c (scm_start_stack): Copy source when evaluating. (If we 
don't, we may end up passing memoized source to a transformer.)

26e1985495 Removed last change. (Replaced by a better change.) 1998-11-10 07:58:32 +00:00
Mikael Djurfeldt
7a13c3ae7b * stacks.c (read_frame): Bugfix: Removed lingering `else' 
statement.
(read_frames): Use SCM_MACROEXPP.
 1998-11-10 07:57:51 +00:00
Mikael Djurfeldt
e40a5fc8ce * backtrace.c (get_applybody): Help function which lookups the 
first body form of the apply closure.
(display_error_body): Prevent the source of the first form of the
apply closure from being printed in error messages.

 1998-11-10 06:10:33 +00:00
Mikael Djurfeldt
7c3540523f * eval.c (SCM_CEVAL): Use SCM_SET/CLEAR_MACROEXP. 1998-11-10 06:10:11 +00:00
Mikael Djurfeldt
77debe3c6b * debug.h (SCM_SET_MACROEXP, SCM_CLEAR_MACROEXP, SCM_MACROEXPP): 
Replaces SCM_MACROFRAME, SCM_MACROFRAMEP.
 1998-11-10 06:09:55 +00:00
Mikael Djurfeldt
7c9398015e * stacks.c (read_frames): Skip gsubr frames in backtraces. (They 
don't contain interesting information since all arguments are
present in the frame which applies the compiled closure anyway.);
Skip the transformer application frames.
 1998-11-09 16:46:08 +00:00
Mikael Djurfeldt
56977059e4 * print.c (scm_iprin1): Print gsubrs as primitives. 1998-11-09 15:52:29 +00:00

358785a62e * readline.c, readline.h (scm_readline_options, 
scm_readline_opts): Moved readline options here.
 1998-11-09 14:15:30 +00:00
Mikael Djurfeldt
3f2f0599c3 * read.c, read.h (scm_read_options, scm_read_opts): Removed 
readline options.  They should reside in their own options array.
 1998-11-09 14:14:49 +00:00
Mikael Djurfeldt
368bf056f9 * eval.c (SCM_CEVAL): Mark macro frames at `handle_a_macro' so 
that we can identify these in a backtrace.  (This change doesn't
introduce any significant speed penalty.)
* eval.c: Added note about `serial-map' using scm_map.
 1998-11-09 14:13:31 +00:00
Mikael Djurfeldt
e28748e4f0 * debug.h (SCM_MACROFRAME, SCM_MACROFRAMEP): New frame type. 1998-11-09 14:13:06 +00:00

9fdba2fee5 * readline.c (scm_read_history, scm_write_history): Bugfix: Use 
SCM_ROCHARS instead of SCM_CHARS.
 1998-11-06 18:15:40 +00:00
Mikael Djurfeldt
d1c90db5d6 * ports.c (scm_unread_string): Bugfixes: Check for SCM_STRINGP, 
not SCM_ROSTRINGP; use SCM_ROUCHARS instead of SCM_UCHARS.
 1998-11-06 18:15:12 +00:00
Mikael Djurfeldt
44e0a162a2 * ports.h (SCM_CUC): #define as ~SCM_CRDY instead of 0x001fffffL. 
This is quite important since the latter clears the
FPORT_READ_SAFE and FPORT_WRITE_SAFE flags causing flushes at
every single character read...

77c25af7d1 * print.c (scm_iprin1): Removed suspect looking (and indeed 
malevolent) semicolon after test for user supplied closure print
procedure.  (Thanks to Telford Tendys.)
 1998-11-03 16:09:29 +00:00
Mikael Djurfeldt
263a691f04 * options.c (scm_options, scm_init_options): GC-protect option

element.

Mikael Djurfeldt
82dc9f574f * list.c (scm_sloppy_memq): Removed sloppy_mem_check. 
(scm_memq, scm_memv, scm_member): Do argument checking *before*
starting to search the list.  Removed call to sloppy_mem_check.
* list.c, list.h (scm_delq1_x, scm_delv1_x, scm_delete1_x): New
procedures: Same as scm_delq_x et al, but delete maximally one
element.

83336ffd60 Removed some #if 0 which slipped through in previous change 1998-11-01 16:57:40 +00:00
Mikael Djurfeldt
d0b7bad785 * eval.c: Don't #define scm_lookupcar to scm_lookupcar1. Instead 
make sure that there always is a "real" scm_lookupcar.
