160bb34a53 * Removed unused object parameter from SCM_ASSYNT. 2001-03-15 09:50:20 +00:00
Martin Grabmüller
67e8151b65 * load.c (scm_primitive_load, scm_primitive_load_path), 
(scm_sys_search_load_path): Corrected docstrings (file ->
	filename).

	* eval.c (scm_force): Added texinfo markup to docstring.
	(scm_promise_p): Renamed parameter to `obj' to match docstring.

	* debug-malloc.c: Reinserted #include <stdio.h>.

586d7da237 * eval.c (scm_m_letstar): Removed check for duplicate bindings. 
Duplicate bindings are OK in a let* since a let* is semantically
equivalent to a nested set of let:s.

db4b4ca64f * Eliminate some calls to scm_wta. 2001-03-04 17:09:34 +00:00
Marius Vollmer
185ab0ef10 * eval.c (scm_s_duplicate_bindings): New error message. 
(scm_m_letrec1, scm_m_letstar): Check for duplicate bindings.

5280aacabc * eval.h (SCM_EVALIM2): New macro. Use it when a 
immediate, literal constant should be evaluated.
* eval.c (scm_s_duplicate_formals): New error message string.
(scm_c_improper_memq): New function.
(scm_m_lambda): Check for duplicate arguments.
(scm_ceval, scm_deval): When executing a body: only cons a new
toplevel environment frame when it is different from the
existing one; use EVALCAR instead of SIDEVAL so that we can properly
check for empty combinations; use SCM_EVALIM2 for the same reason
in the non-toplevel loop.
(nontoplevel_cdrxnoap, nontoplevel_cdrxbegin, nontoplevel_begin):
New labels with the meaning of their non-"nontoplevel" partners,
but they are used when it is known that the body is not evaluated at
top-level.
(scm_apply, scm_dapply): use SCM_EVALIM2 to get proper error
reporting for empty combinations.

2069af3835 * Minor docstring updates. 2001-02-23 20:24:15 +00:00
Marius Vollmer
23c46fa69a * eval.c (scm_ceval, scm_deval): When evaluating expressions on 
top level, create a fresh top-level environment for each
expression instead of mutating the exisint frame.  This is
important when that frame is closed over.
 2001-02-22 20:54:12 +00:00
Marius Vollmer
a820af98a7 Only check number of arguments for closures, see last change. 
I just love this evaluator, man.
 2001-02-21 22:52:59 +00:00
Marius Vollmer
e37a4fbae1 * eval.c (scm_ceval, scm_deval): Check for wrong number of args 
before applying arrow procedure in `cond' and before applying
receiver procedure in call-with-current-continuation.
(scm_i_eval): Do not invoke scm_copy_tree in argument in SCM_XEVAL
macro.  The argument is expanded more than one time.
 2001-02-21 20:14:47 +00:00
Martin Grabmüller
b3f26b140b (scm_eval_options_interface, scm_evaluator_traps, s_scm_nconc2last): 
Added docstrings.

018008c17f Do not use "//" comment syntax. It's not ANSI. 2001-02-15 15:39:32 +00:00
Marius Vollmer
a2abcb5823 * eval.c (scm_ceval, scm_deval): use `SIDEVAL' instead of 
SCM_CEVAL when evaluating subforms of `begin' forms.  SCM_CEVAL
can not deal with immediates.
 2001-02-13 01:09:00 +00:00
Marius Vollmer
4163eb7236 * eval.c (scm_ceval, scm_deval): Recognize when `begin' is being 
evaluated at top-level and synronize lookup closure before
executing every subform.
(scm_primitve_eval_x, scm_primitive_eval): New functions.
(scm_eval_x, scm_eval): Reimplement in terms of
scm_primitive_eval_x and scm_primitive_eval, respectively.
 2001-02-11 18:13:07 +00:00
Marius Vollmer
aa767bc58f * modules.h (scm_selected_module, scm_current_module): Renamed 
scm_selected_module to scm_current_module to synchronize Scheme
and C names.
(scm_select_module, scm_set_current_module): Likewise.  Changed
all uses.
 2001-02-08 18:49:52 +00:00

41ee56dde3 * eval.c (SCM_APPLY): Check that primitives which take 1 arg 
really get that arg.

Dirk Herrmann
5d2b97cd07 * Fixed the changelog entry regarding re-introduction of struct member 
properties (I continuously talked of member 'documentation' instead)

 2000-12-28 16:49:09 +00:00
Dirk Herrmann
2e9c835db9 * Make sure, re-entering the dynamic scope of an eval statement will 
restore the latest selected module.

* remove uses of older GC marking and cell accessing macros
 2000-12-06 15:16:59 +00:00
Gary Houston
5f144b105d * use an applicable SMOB to represent continuations, instead of a 
custom tc7 type.  This will make it easier to support R5RS
	multiple value continuations, without the use of a Scheme-level
	wrapper.

	* continuations.c (scm_tc16_continuation, continuation_mark,
	continuation_free, continuation_print, continuation_apply):
	new SMOB support.
	(scm_make_continuation): new procedure, replaces scm_make_cont
	with a different interface.
	(copy_stack_and_call, scm_dynthrow, scm_init_continuations): rewritten.
	(CHEAP_CONTINUATIONS): removed non-working code completely.
	(scm_call_continuation): removed.
	* continuations.h (struct scm_contregs): add num_stack_items and
	stack fields.  previously stack was stored following this struct:
	use a tail array instead.
	(SCM_CONTINUATIONP): new macro.
	(SCM_CONTINUATION_LENGTH, SCM_SET_CONTINUATION_LENGTH):
	rewritten.
	(SCM_SET_CONTREGS): removed.
	* tags.h: removed scm_tc7_contin (was tag 61).
	* debug.c, gc.c, hash.c, print.c, procprop.c, procs.c:
	removed scm_tc7_contin support.
	* eval.c: use scm_make_continuation instead of scm_make_cont.
	don't set jump buffers here.  remove scm_tc7_contin support.
	* init.c, root.c: create SMOB continuation for rootcont instead
	of scm_tc7_contin.  call scm_init_continuations before
	scm_init_root.
	* root.c: remove support for static jmpbuf.  It's not used by
	default and I broke it.  create SMOB continuation for rootcont.
	* stacks.c: use SCM_CONTINUATIONP.
