[bpt/guile.git] / ice-9 / ChangeLog

2004-09-02  Kevin Ryde  <user42@zip.com.au>

	* format.scm (format:out): Ignore excess arguments, per common lisp.

	* format.scm (format:out-num-padded): Print "+" on 0 under @ modifier.

2004-08-27  Kevin Ryde  <user42@zip.com.au>

	* regex.scm (regexp-quote): [ and | must be quoted.  Quote ( ) { + ?
	using char class [(] etc since \( in fact makes them become special in
	regexp/basic.

2004-08-25  Kevin Ryde  <user42@zip.com.au>

	* and-let-star.scm (and-let*): Give #t for an empty body, per srfi-2
	spec, previously came out as an empty (begin).

2004-08-25  Marius Vollmer  <mvo@zagadka.de>

	* boot-9.scm (%cond-expand-features): Added srfi-13 and srfi-14.

2004-08-20  Marius Vollmer  <marius.vollmer@uni-dortmund.de>

	* debugger/utils.scm (display-source): Use unmemoize-expr instead
	of unmemoize.
	(write-frame-short/expression): Likewise.

2004-08-18  Kevin Ryde  <user42@zip.com.au>

	* and-let-star.scm: Add cond-expand-provide srfi-2, since this module
	provides that feature.
	* receive.scm: Add cond-expand-provide srfi-8, since this module
	provides that feature.

2004-08-09  Marius Vollmer  <mvo@zagadka.de>

	From Matthias Koeppe.  Thanks!
	
	* pretty-print.scm (generic-write): In the local procedure `wr', use
	object->string to print all data (except for the reader macros),
	rather than implementing an own printer.  The user-visible
	difference is that procedures and control characters like #\tab
        are now printed in the same way as by `write'.

2004-08-09  Kevin Ryde  <user42@zip.com.au>

	* slib.scm (*features*): Remove array and array-for-each, core
	definitions are insufficient for latest slib.
	(t, nil): New constants slib says are supposed to exist.
	(call-with-open-ports, browse-url): New functions for latest slib.
	Implementations taken from Template.scm (public domain).
	(open-file): Extend core definition to accept symbols for the mode,
	required by latest slib.
	(delete-file): Replace core definition with version returning #t/#f as
	per slib spec.
	(system): Mark as #:replace to suppress override warning, use new
	style "(@ (guile) system)" to call core function.

2004-05-25  Matthias Koeppe  <mkoeppe@mail.math.uni-magdeburg.de>

	* format.scm: Remove the arbitrary limit of 100 iterations for the
	~{...~} control structure.

2004-07-10  Kevin Ryde  <user42@zip.com.au>

	* and-let-star.scm (and-let*): Remove unused variable "val".
	* pretty-print.scm (read-macro-prefix): Remove unused variable "tail".

	* boot-9.scm (%cond-expand-features): Add srfi-6 which is in the core.

	* safe-r5rs.scm (re-export): Uncomment numerator, denominator,
	rationalize, since they now exist.
	
2004-07-05  Kevin Ryde  <user42@zip.com.au>

	* slib.scm (system): Correction to redefinition, now guile is stricter
	about when a define binding comes into existance.

2004-05-29  Dirk Herrmann  <dirk@dirk-herrmanns-seiten.de>

	* boot-9.scm: Reordered definitions such that macro definitions
	preceed their first usage.  Include and define deprecated stuff
	late in the file to have a better change of detecting accidental
	uses of deprecated definitions. Further, unified the layout a
	little and grouped definitions more cleanly into topics.

2004-05-24  Marius Vollmer  <mvo@zagadka.de>

	* history.scm (use-value-history): Use resolve-interface instead
	of resolve-module so that only the exported bindings are searched.
	(save-value-history): Export the newly defined variable.  Reported
	by Wolfgang Jaehrling.
	
2004-05-04  Dirk Herrmann  <dirk@dirk-herrmanns-seiten.de>

	* boot-9.scm (resolve-module): Always start searching from the
	root module.  This will allow the C equivalent scm_resolve_module
	to work, independent of what the current module is.

2004-02-18  Marius Vollmer  <mvo@zagadka.de>

	* boot-9.scm (top-repl): Make the (guile-user) module use the
	(ice-9 r5rs) module.

2004-02-12  Mikael Djurfeldt  <djurfeldt@nada.kth.se>

	* boot-9.scm (module-map): Renamed hash-map -> hash-map->list.

2004-02-09  Neil Jerram  <neil@ossau.uklinux.net>

	* debugger/trap-hooks.scm (debug-hook-membership): New, exported.

	* debugger/commands.scm (debug-trap-hooks): New, exported.

2004-02-08  Mikael Djurfeldt  <djurfeldt@nada.kth.se>

	* debugger/breakpoints/Makefile.am (TAGS_FILES),
	debugger/Makefile.am (TAGS_FILES), Makefile.am (TAGS_FILES): Use
	this variable instead of ETAGS_ARGS so that TAGS can be built
	using separate build directory.

2004-01-20  Neil Jerram  <neil@ossau.uklinux.net>

	* boot-9.scm (error-catching-loop): Back out 2003-11-19 change to
	lazy-handler-dispatch lookup.

2004-01-12  Marius Vollmer  <mvo@zagadka.de>

2004-01-11  Kevin Ryde  <user42@zip.com.au>

	* slib.scm (system): New function, giving an exit code return in
	accordance with slib spec.
	
	Revert this, it breaks test-suite/tests/r5rs_pitfalls.test where
	false-if-exception is used within syntax-rules.  (Suspect syntax-rules
	ought to support this sort of thing, but it doesn't right now.)
	* boot-9.scm (false-if-exception): Unquote catch and lambda, so as not
	to depend on expansion environment.

2004-01-07  Marius Vollmer  <marius.vollmer@uni-dortmund.de>

	* boot-9.scm (with-fluids): Use with-fluid* when only one fluid is
	being set.

2004-01-07  Kevin Ryde  <user42@zip.com.au>

	* q.scm (q-pop!): Should be "null?" not "not" for end-of-list.
	Reported by Richard Todd.

2004-01-04  Kevin Ryde  <user42@zip.com.au>

	* boot-9.scm (false-if-exception): Unquote catch and lambda, so as not
	to depend on expansion environment.

	* slib.scm (-1+, <?, <=?, =?, >?, >=?): Define as aliases for 1-, <,
	<=, =, >, >= respectively, required by slib 'rev2-procedures but no
	longer in the guile core.

2003-11-19  Neil Jerram  <neil@ossau.uklinux.net>

	* debugger.scm: Change ui-* calls to gds-*.
	(debug-on-error): Debug if throw key is in specified syms, not if
	it isn't!  Also throw 'abort after debugging, so as to skip the
	REPL's backtrace.

	* debugger/behaviour.scm (*trap*): New variable, stores trap type.
	(before-enter-frame-hook, before-apply-frame-hook,
	before-exit-frame-hook): Set here.
	(debug-if-flag-set): Passed into flags on debug-stack call.
	(at-step, at-next): Changed to debug at frame exit points as well.

	handler.

2003-10-12  Marius Vollmer  <mvo@zagadka.de>

	* ftw.scm (directory-files): Close dir-stream when done.  Thanks
	to Paul Jarc!

2003-10-09  Kevin Ryde  <user42@zip.com.au>

	* poe.scm (funcq-assoc): Rewrite, don't assume '() is false, and

	(ui-command-loop): Call ui-disable-async-thread and
	ui-continue-async-thread.

	progress on new debugging front end).

2003-09-24  Neil Jerram  <neil@ossau.uklinux.net>

	New.

	* debugger/behaviour.scm (debug-if-flag-set): Display debug entry

	change, need to watch out for stdin==stderr or stdout==stderr.

2003-09-15  Marius Vollmer  <mvo@zagadka.de>

	* format.scm (format): Rewritten as a big letrec to make it
	reentrant.  No mutex is necessary.  Thanks to Clinton Ebadi!

2003-09-13  Kevin Ryde  <user42@zip.com.au>

	* boot-9.scm (file-exists?): Use stat rather than access?, so as to
	follow the effective UID/GID not the real ID.  file-exists? is
	normally used as a prelude to opening or some other operation, and
	it's the effective ID which will apply there.  Emacs file-exists-p
	uses stat, presumably for the the same reason.

2003-09-12  Marius Vollmer  <mvo@zagadka.de>

	* boot-9.scm (make-autoload-interface): Use a proper hashtable as
	the obarray, not an empty vector.
	(make-module): Always construct a hashtable for the obarray, even
	for empty ones.

	* format.scm (format:error): Use 'format:format' instead of
	'format' since the latter will lock the mutex again that we have

	* boot-9.scm (while): Rewrite, continue as proper escape, break
	without return value, break and continue new for each while form,
	don't depend on bindings in expansion environment.

	* popen.scm (open-process): Close input-fdes, output-fdes and
	error-fdes after duping them to 0, 1 and 2.

2003-06-19  Kevin Ryde  <user42@zip.com.au>

	* threads.scm (parallel): For no forms, use `(values)' not `(begin)'.

	vector constant.

	New.

	* boot-9.scm (display-usage-report): Use keyword->symbol instead
	of keyword-symbol, which doesn't exist.  Thanks to Kevin Ryde.

	* hcons.scm (hashq-cons-get-handle): Pass only the expected four
	arguments to hashx-get-handle.  Thanks to Kevin Ryde!

	* lineio.scm (make-line-buffering-input-port) Pass 0 as second
	argument to string-ref.  Thanks to Kevin Ryde!

2003-04-25  Mikael Djurfeldt  <mdj@kvast.blakulla.net>

	* serialize.scm: New file.

2003-04-24  Mikael Djurfeldt  <djurfeldt@nada.kth.se>

	* boot-9.scm (duplicate-handlers): Make sure the merge-generics

2003-01-20  Mikael Djurfeldt  <djurfeldt@nada.kth.se>

	* occam-channel.scm (alt): New syntax.

2003-01-19  Mikael Djurfeldt  <djurfeldt@nada.kth.se>

2003-01-16  Mikael Djurfeldt  <djurfeldt@nada.kth.se>

	* psyntax.ss (build-data): Don't quote self-evaluating expressions
	in output.  (We normally *would* like also these expressions to be

	self-evaluating).
	(sc-chi): Export chi as sc-chi.
	(external-macro): New syntax type.

	* boot-9.scm (define-private): Undid my changes from 2002-11-16
	until Guile supports hygienic macros.

2002-11-17  Neil Jerram  <neil@ossau.uklinux.net>

	* emacs.scm (emacs-load): Locally define `read-and-eval!', as it
	has been removed from the core.

2002-11-16  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* syncase.scm (define-syntax, eval-when, fluid-let-syntax,
	identifier-syntax, let-syntax, letrec-syntax, syntax, syntax-case,

	* format.scm (format): Use 'monitor' properly.  Not the definition
	needs to be restricted, the actual function needs to be.

2002-11-05  Neil Jerram  <neil@ossau.uklinux.net>

	* boot-9.scm (define-option-interface): Fix to "simplification"
	change below.

	* debugger/breakpoints/source.scm: Enable source property
	recording when module is loaded.
	(##): Cope with ports whose `filename' is not a string.

2002-11-04  Neil Jerram  <neil@ossau.uklinux.net>

	* boot-9.scm (define-option-interface): Simplify code-generation
	code.

	* debugger/command-loop.scm (read-and-dispatch-command): Import
	set-readline-prompt dynamically if we need to.  (Previous
	arrangement didn't work if this module was loaded before (ice-9
	readline).)

2002-11-03  Marius Vollmer  <mvo@zagadka.ping.de>

	* format.scm (format): Wrap a monitor around format:format since
	it is not thread-safe.

2002-10-27  Marius Vollmer  <mvo@zagadka.ping.de>

	* threads.scm (%thread-handler): Explicitely return '#f'.  This
	value will be returned by join-thread.

2002-10-26  Neil Jerram  <neil@ossau.uklinux.net>

	Merging debugger enhancements previously in separate
	`guile-debugger' package ...
	
	* debugger.scm: Factored out into the following constituent parts

	debugger when entering it from breakpoints).
	(debug-stack): New.
	(debug): Rewrite to use more general `debug-stack'.

	* debugger/commands.scm, debugger/command-loop.scm,
	debugger/state.scm, debugger/utils.scm: New files containing bits
	of old (ice-9 debugger), plus some rewriting and enhancements for

	(make-state): Extend to optionally take flags.
	(state-flags): New, accessor for flags field.

	location in a way that is more easily trackable by Emacs.
	
	* debugger/commands.scm (assert-continuable, continue, finish,
	trace-finish, step, next): New debugger commands for continuing
	execution from a breakpoint.

	* debugger/behaviour.scm, debugger/breakpoints.scm,
	debugger/breakpoints/procedural.scm,

2002-10-21  Marius Vollmer  <mvo@zagadka.ping.de>

	* threads.scm (%thread-handler): Do not call unmask-signals, that
	should be unnecessary now.

2002-10-20  Mikael Djurfeldt  <mdj@linnaeus>

	* boot-9.scm (top-repl): Look for use-emacs-interface in
	guile-user-module (should it be there?) instead of
	the-root-module.

	* boot-9.scm (top-repl): Use 2 as the limit when saving the stack.

2002-10-09  Neil Jerram  <neil@ossau.uklinux.net>

	* buffered-input.scm (make-buffered-input-port): Build an
	input-waiting thunk for just extended version of make-soft-port.
