[bpt/guile.git] / srfi / ChangeLog

2001-08-04  Gary Houston  <ghouston@arglist.com>

	* srfi-1.scm (filter): replaced with a tail-recursive version.
	(remove): implement using filter, to make it tail-recursive.

2001-07-31  Gary Houston  <ghouston@arglist.com>

	* srfi-14.c (scm_char_set_diff_plus_intersection): wasn't correctly
	accounting for the (char-set-union cs2...) in the spec.  i.e.,
	(char-set-diff+intersection a) -> copy-of-a, empty-set
	and the following are equivalent:
	(char-set-diff+intersection a (char-set #\a) (char-set #\b))
	(char-set-diff+intersection a (char-set #\a #\b))

	(scm_char_set_xor_x): disabled the side-effecting code, since it
	gives inconsistent results to scm_char_set_xor for the case
	(char-set-xor! a a a).
	
	(scm_char_set_diff_plus_intersection_x): added cs2 argument, since
	two arguments are compulsory in final spec.  also similar changes
	as for scm_char_set_diff_plus_intersection.
	* srfi-14.h (scm_char_set_diff_plus_intersection_x): added cs2.

2001-07-22  Gary Houston  <ghouston@arglist.com>

	* srfi-14.c (scm_char_set_intersection, scm_char_set_xor): remove
	the compulsory cs1 arguments: all args are optional in final spec.

	* srfi-14.h: declarations updated.

2001-07-18  Martin Grabmueller  <mgrabmue@cs.tu-berlin.de>

	* srfi-11.scm, srfi-8.scm: Update copyright notice.

2001-07-17  Martin Grabmueller  <mgrabmue@cs.tu-berlin.de>

	* srfi-14.c: Okay.  Now I got it.  Really.  This time it's fixed.
	Guaranteed. (Maybe)
	
	* srfi-19.scm: Define `current-time' before exporting it.

2001-07-17  Martin Grabmueller  <mgrabmue@cs.tu-berlin.de>

	* srfi-14.c: Fix for bug caused by brain-malfunctioning on my
	side.  Bit sets were handled wrong because I couldn't tell bit
	counts from byte counts.  Also, the bit array should be 256 / 8
	bytes long.  Thank you, Gary!	

	Removed unnecessary protoype for scm_char_set_copy.

2001-07-16  Gary Houston  <ghouston@arglist.com>

	* srfi-14.scm: export string->char-set!, not string-char-set!.

	* srfi-14.c (scm_char_set_ref, scm_char_set_cursor_next,
	scm_end_of_char_set_p): reject negative	cursor values.
	(scm_list_to_char_set, scm_list_to_char_set_x): when reporting
	type error in list component, omit the position (was always 1).

2001-07-16  Martin Grabmueller  <mgrabmue@cs.tu-berlin.de>

	(scm_char_set_map): Bug-fix: char-set-map was modifying the
	argument instead of the return value.

2001-07-16  Martin Grabmueller  <mgrabmue@cs.tu-berlin.de>

	* srfi-14.c: Allocate correct memory size for charsets (32 bytes),
	use this value for initializing and comparing charsets.
	(scm_char_set_hash): Use ``better'' hash algorithm which produces
	more values.

2001-07-15  Gary Houston  <ghouston@arglist.com>
	
	* srfi-14.c (scm_char_set_hash): recognise 0 instead of #f in the
	opt arg to give default bound, as in final spec.  don't allow
	negative bounds.
	(scm_char_set_hash): bug fix: was overrunning the buffer and
	calculating based on garbage.
	(scm_char_set_eq, scm_char_set_leq): fix argument number in error
	reporting: wasn't incremented due to macro coding.
	(scm_char_set): report argument number in error reporting: was
	hard coded to 1.  remove a couple of local variables.

2001-07-13  Marius Vollmer  <mvo@zagadka.ping.de>

	* srfi-2.scm (and-let*): Use `re-export-syntax' instead of
	`export-syntax'.

2001-07-11  Gary Houston  <ghouston@arglist.com>

	* srfi-14.c (s_scm_char_set_eq): bug fix: (char-set=) should
	return #t instead of giving wrong-number-of-arguments . take a
	single "rest" argument.  use memcmp instead of a loop to compare
	the values.
	(s_scm_char_set_leq): similarly, (char-set<=) should return #t.
	take a single "rest" argument.
	srfi-14.h: update the declarations.

2001-07-09  Martin Grabmueller  <mgrabmue@cs.tu-berlin.de>

	* README: Cleanup.

2001-07-06  Gary Houston  <ghouston@arglist.com>

	* srfi-1.scm (iota, map, for-each, list-index, member, delete,
	delete!, assoc): roll back the previous change.  instead place
	dummy definitions in a deprecated block at the beginning as in
	srfi-13.scm.
	
2001-07-06  Rob Browning  <rlb@defaultvalue.org>

	* srfi-19.scm (priv:locale-reader): don't need open-output-string.

2001-07-03  Gary Houston  <ghouston@arglist.com>

	* srfi-1.scm (iota, map, for-each, list-index, member, delete,
	delete!, assoc): don't export until the new bindings have been
	created.  otherwise "export" thinks they are being re-exported and
	a deprecation warning is produced.
	(map-in-order): defined and exported, to support lists of unequal
	length.

2001-07-03  Martin Grabmueller  <mgrabmue@cs.tu-berlin.de>

	* srfi-1.scm (list-tabulate): Do not go into infinite loop for
	invalid arguments.  Same fix for several other procedures (do not
	use zero?, use <= 0).

2001-07-02  Martin Grabmueller  <mgrabmue@cs.tu-berlin.de>

	* srfi-1.scm: Replaced calls to `map' in several procedures to
	calls to `map1'.
	(map, for-each): New procedures, extended from R5RS.

	(scm_char_set_unfold_x, scm_char_set_for_each)
	(scm_char_set_map, scm_char_set_filter)
	(scm_char_set_filter_x, scm_char_set_count)
	(scm_char_set_every, scm_char_set_any): Replace calls to
	scm_apply() with the corresponding scm_call_N() functions.

	(scm_char_set_diff_plus_intersection_x): Replace deprecated macros
	SCM_LISTN with calls to scm_list_N().

	* srfi-13.c (scm_string_tabulate, scm_string_map)
	(scm_string_map_x, scm_string_unfold)
	(scm_string_unfold_right): Replace deprecated macros SCM_LISTN
	with calls to scm_list_N().

	* srfi-13.c (scm_string_any, scm_string_every),
	(scm_string_tabulate, scm_string_trim),
	(scm_string_trim_right, scm_string_trim_both),
	(scm_string_compare, scm_string_compare_ci),
	(scm_string_indexS, scm_string_index_right),
	(scm_string_skip, scm_string_skip_right, scm_string_count),
	(scm_string_map, scm_string_map_x, scm_string_fold),
	(scm_string_fold_right, scm_string_unfold),
	(scm_string_unfold_right, scm_string_for_each),
	(scm_string_filter, scm_string_delete): Replace calls to
	scm_apply() with the corresponding scm_call_N() functions.

2001-06-27  Martin Grabmueller  <mgrabmue@cs.tu-berlin.de>

	* Makefile.am: Added SRFI-4 files in various places.

	* srfi-4.c, srfi-4.h, srfi-4.scm: New files implementing SRFI-4.

2001-06-26  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* srfi-13.c (scm_string_copyS, scm_string_take, scm_string_drop,
	scm_string_take_right, scm_string_drop_right, scm_string_trim,
	scm_string_trim_right, scm_string_trim_both, scm_string_tokenize):
	Use scm_mem2string instead of scm_makfromstr.

	(scm_reverse_list_to_string, string_titlecase_x):  Prefer

2001-06-25  Marius Vollmer  <mvo@zagadka.ping.de>

	* srfi-8.scm: Use `re-export-syntax' to correctly re-export
	`receive'.

2001-06-18  Matthias Koeppe  <mkoeppe@mail.math.uni-magdeburg.de>

        The SRFI-19 implementation was completely broken.  Already the
	reference implementation did not handle DST and time zones
	properly and relied on non-R5RS-isms like passing reals to
	`quotient'.  For Guile, some additional fixes were needed because
	of the incomplete numeric tower implementation.  See also
	srfi-19.test. 
	
	* srfi-19.scm (date-zone-offset): Fixed typo in export clause.
	(add-duration): Renamed from priv:add-duration. 
	(priv:time-normalize!): Handle fractional nanoseconds; remove
	duplicate definition.
	(priv:current-time-tai): Fixed typo.
	(time=?, time<=?): Fixed typos.
	(time-tai->time-utc, time-utc->time-tai,
	time-utc->time-monotonic): Use make-time-unnormalized instead of
	make-time when uninitialized time fields are used.
	(set-date-nanosecond!, set-date-second!, set-date-minute!,
	set-date-hour!, set-date-day!, set-date-month!, set-date-year!,
	set-date-zone-offset!): Define.
	(priv:local-tz-offset): Take an extra argument in order to handle
	DST effects.
	(time-utc->date, time-tai->date, time-monotonic->date): Handle the
	changed signature of priv:local-tz-offset. Don't pass non-integer
	arguments to quotient (non-R5RS, not supported by Guile). 
	(date->time-utc): Ensure that seconds in a date structure are
	always exact integers.  Handle DST properly.
	(current-date, julian-day->date, modified-julian-day->date):
	Handle the changed signature of priv:local-tz-offset.  
	(julian-day->time-utc): Reverted earlier inexact->exact hack;
	make-time now handles inexact arguments.
	(priv:locale-print-time-zone): At least print the numerical time
	zone. 
	(priv:integer-reader): Fixed named let iteration.
	(priv:read-directives): Use set-date-month! instead of
	priv:set-date-month! etc.
	(string->date): Handle DST properly.

2001-06-07  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* srfi-14.c (charset_print): Mark unused parameters with
	SCM_UNUSED.

2001-06-07  Martin Grabmueller  <mgrabmue@cs.tu-berlin.de>

	* srfi-1.scm (fold, fold-pair): Fixed a buggy call to apply.
	(delete-duplicates): Now the first occurrence of an element is
	retained, as required.
	(member, assoc): Fixed wrong order of equality predicate
	application.

	* README: Update.

	* srfi-1.scm: New file.

2001-06-04  Marius Vollmer  <mvo@zagadka.ping.de>

	Added exception notice to all files.

2001-05-31  Martin Grabmueller  <mgrabmue@cs.tu-berlin.de>

	* srfi-14.scm, srfi-13.scm: Use `load-extension' for loading the
	shared library.

2001-05-31  Michael Livshin  <mlivshin@bigfoot.com>

	* Makefile.am (MKDEP): copied from libguile/Makefile.am, just in
	case.
