Raw Blame History

Thu Sep 26 19:38:42 1996 Erick Gallesio <eg@unice.fr>
* STk-3.1.1 Release
* Demos/amib.stklos: Accessing help is now stk:show-help-file (the
change was not reported)
Wed Sep 25 14:40:21 1996 Erick Gallesio <eg@unice.fr>
* Src/slib.c (STk_delete_Tcl_child_Interp): new function which must
called by a child process just after a fork. This function is
necessary to allow the dynamic loading of posix.so in snow
(otherwise some Tk symbols are undefined).
* Extensions/posix.c (posix_fork): Use now STk_delete_Tcl_child_Interp.
* Src/number.c: Interface has been added for the Frank Schmuelling
complex-number package. Don't rely on it, since rationnal and
complex numbers will be present in a future release. As soon as the
full tower will be implemented in STk, this door will be closed.
Tue Sep 24 18:26:06 1996 Erick Gallesio <eg@unice.fr>
* Lib/dialog.stk: The text of the dialog was reset to a message,
instead of a label (when was the change done?)
Mon Sep 23 22:52:10 1996 Erick Gallesio <eg@unice.fr>
* Src/signal.c: A lot of modifications in signal handling. Major
rewrite of some procedures. The '^Z' signal works again. BTW, I
was unable to correctly catch a SEGV on linux (which is necessary to
find that no more memory is available on Linux, since malloc never
returns NULL this OS. Need more work.
Sun Sep 22 23:54:44 1996 Erick Gallesio <eg@unice.fr>
* Src/toplevel.c (finish_initialisation): replaced the hard-coded
call to signal when using -f option to a call to the
STk_set_signal_handler.
* Src/slib.c (cannot_allocate): new private procedure called when
there is no more memory during a must_malloc or a must_realloc (the
old behaviour was incorrecte since it uses cons whereas there was no
more memory, conducting to a buggy report-error message). However,
the copy on write schem used by Linux cannot be detected by this
procedure. It seems that we have to wait a SIGSGV signal.
Tue Sep 17 10:03:49 1996 Erick Gallesio <eg@unice.fr>
* Src/toplevel.c: Bug correction: only create the stdin handler when
the process is interactive (Otherwise, STk interpreters launched in
backgound by system keep locked -- heavily used in the
Doc/README.html demo)
* STklos/Tk/Composite/Multipaned.stklos: Orientation of Multi-paned
didn't work since it was done with differents keywords (:orientation
and :position) in some places (thanks to MIZUSHIMA Kazunori
<mizkaz@keiou.trad.pfu.co.jp>)
Fri Sep 13 08:22:41 1996 Erick Gallesio <eg@unice.fr>
* STklos/Tk/Tk-methods.stklos: Bug correction in a method of focus
(Erik Ostrom <eostrom@research.att.com>)
* Src/io.c:
* Src/port.c: char-ready? was incorrect when used on stdin
(thanks to Erick Ostrom)
* STklos/Tk/Text.stklos: Correction of the value field of text
widgets. Tk always add a newline at end of buffer.
* Lib/tk-init.stk (%redefine-Tk-command): After STklos was loaded,
each call to focus implies the loafing of file focus.stk !!
* Extensions/socket.c: Added support for sockets on Win32 (thanks to
Caleb Deupree <cdeupree@erinet.com>)
* Src/unix.c: Added the VC++ support for file globbing (thanks to
Caleb Deupree <cdeupree@erinet.com>)
Wed Sep 11 23:05:32 1996 Erick Gallesio <eg@unice.fr>
* Src/tk-main.c: command line argument handling for -geometry was
broken. Thanks to Harvey J. Stein <abel@netvision.net.il>
Fri Sep 6 18:20:28 1996 Erick Gallesio <eg@unice.fr>
* Extensions/stack.c: Replaced FILEPTR by PORT_FILE in the stack
demo. Thanks to Jean-Marie Kubek <kubek@gmm.insa-tlse.fr>
* configure.in: Get rid of '-n' on echo commands. This option is not
supported under Solaris 2.x
Wed Sep 4 13:16:38 1996 Erick Gallesio <eg@unice.fr>
* configure.in: X11 libs/includes in non standard place were not taken
into account even when a --x-libraries or a --x-includes was given
to the configure script.
Mon Sep 2 10:46:06 1996 Erick Gallesio <eg@unice.fr>
* Tk: updraded to Tk4.1p1
* Src/eval.c: Bug correction in eval.c: arguments were not evaluated
when the generic function is implemented in Scheme rather than in C.
(Thanks to Jean-Christophe Pazzaglia <pazzagli@arsenic.unice.fr>)
* Lib/dialog.stk: Added a binding to the dialog window that sets the
result to -1; this is needed in case something happens that destroys
the window, such as its parent window being destroyed.
Thu Aug 29 13:43:13 1996 Erick Gallesio <eg@unice.fr>
* Src/slib.c (STk_quit_interpreter): replaced Tcl_DeleteInterp by a
call to delete the command ".". Otherwise, when the interpreter
delete all the commands and find ".", the process becomes
recursive. This yield problems when the interpreter has already
allocated images.
Sat Aug 24 15:48:40 1996 Erick Gallesio <eg@unice.fr>
* Src/io.c (STk_getc): Bug correction: when a handler was set on
stdin, and the process was interactive, the system loops
indefinitely.
* Lib/text.stk: Typo on *tk-strict-motif* for <ButtonRelease-2>
Fri Aug 23 22:24:33 1996 Erick Gallesio <eg@unice.fr>
* Src/toplevel.c (finish_initialisation): Modifications to allow
using stdin when using the "-f" option. Signaled by Erik Ostrom
<eostrom@research.att.com>
Sat Aug 17 11:21:30 1996 Erick Gallesio <eg@unice.fr>
* Src/io.c: Tcl_DoOneEvent parameter was "TK_DONT_WAIT", which is no
more necessary and which greatly increase cpu usage when used
interactively. Tcl_DoOneEvent is now 0
Tue Aug 13 18:00:10 1996 Erick Gallesio <eg@unice.fr>
* STklos/Tk/Composite/*.stklos: Avoid to use a (require
"Tk-classes") since it can condut to problem if normal widget have
been loaded by hand before (i.e. without using Tk-classes)
* Lib/posix.stk: The definition of posix-access? was inverted.
* Src/posix.c (posix_access): corrected error messages typos.
* Mp/Makefile: replaced make by $(MAKE)
* New directory: Doc/LaTeX-packages: This dictory contains packages
which ares used in documentation but which are absent from some
Latex distributions.
* Lib/process.stk: mispelling in string-append. Grrr.
* Tk/configure: Bug correction: Not everybody has "." in its PATH.
* Tk/unix/Makefile.in: Bug correction signalled by
Matthew.R.Wette@jpl.nasa.gov for X11 include files placed in non
standard place
* Lib/Makefile: Bug correction signalled by
Matthew.R.Wette@jpl.nasa.gov when installing Lib files
* configure.in: Changed Linux 2.x namimg scheme (I forgot that Linux
is now in 2.0!)
Wed Jul 24 00:04:49 1996 Erick Gallesio <eg@unice.fr>
* STk-3.1 Release
* Src/stklos.c: The slot "name" in methods (which was always (buggyly)
set to "???") is gone. A new slot replace it:
"generic-function". The value of this slot is the generic function
to which the method belongs.
Anonymous function have a "generic-function" set to #f.
Potential problem: an anonymous method can be added to two different
GFs. In this case, the slot "generic-function" will be incorrect.
However, this should not be a problem since
1. anonymous method are rare
2. this is only used by STklos to find the class of the gf
(and not the gf itself) of a method when there is no
next-method when we applying a next-method....
* Tk/unix/tkUnixWm.c: A lot of adaptation to Scheme (empty lists
replaced by #f, mainly). This modificcations were needed for amib
whose save/restore didn't work in 3.0.
* Tk/generic/tkPlace.c: Bug correction in the info suboption
Tue Jul 23 10:11:28 1996 Erick Gallesio <eg@unice.fr>
* Src/argv.c (STk_process_argc_argv): has been rewritten and is
table driven now. Parameters are processed analysed
differently now: the "--" option has been added to allow a clear
separation between interpreter arguments and scripts arguments
(as in Tcl). However, interpreter arguments must precede scripts
arguments (this is different from Tcl, but more Unixish).
* Src/tk-main.c: Bug correction: if visual was incorrect the program
enter in an infinite loop.
* Doc/Makefile: Tk Manuals pages are now prefixed by "stk_"
to avoid confusion with original Tk ones. They are always placed
in a subtree of the STk tree installation since it eases
the distribution of binary releases.
* New demo: mc-server a multiple-client server. This is a first
version, because this demo should be graphical to see connections
and deconnection as they arrive. (Next release)
Mon Jul 22 15:53:44 1996 Erick Gallesio <eg@unice.fr>
* BINARY_DISTRIB: description of the way to make binary releases.
Binary release will be stored in ftp://kaolin.unice.fr/Binary
* Lib/init.stk:
Lib/Makefile.in: Adding a site-scheme directory. This is
the standard directory for non standard stuff. Local scheme
files or extensions can be put in this directory.
Sun Jul 21 17:53:35 1996 Erick Gallesio <eg@unice.fr>
* Lib/init.stk: added the variable *shared-suffix*. It is equal to
"so", except on HP-UX whers it is set to "sl". All the Lib/*.stk*
files haves been modified to use this variable rather than hardcode
the usual ".so". I hope it will be OK for HP users.
* Src/port.c (STk_open_file): new mode accepted "a" (for append).
Fri Jul 19 14:36:04 1996 Erick Gallesio <eg@unice.fr>
* Src/posix.c:
- Renamed posix-access to posix-access? (old name exists
for compatibility but will be garbaged in afuture version)
- Added the constant X_OK which was missing
Thu Jul 11 22:21:30 1996 Erick Gallesio <eg@unice.fr>
* Src/posix.c: New primitives: posix_host_name and posix_domain_name
based on gethostname and getdomainname (POSIX.1 does not define
these functions, but ISO/IEC 9945-1:1990 mentions them in B.4.4.1.,
according to the Linux documentation.
* Src/posix.c: New primitive: posix-uname
Fri Jul 5 19:41:38 1996 Erick Gallesio <eg@unice.fr>
* Lib/html.stk: Addition of the <FONT> tag with SIZE and COLOR
sub-tags. This must be compatible with the HTML spec. The <COLOR>
tag which was STk-specific is deleted
Mon Jun 10 00:05:16 1996 Erick Gallesio <eg@unice.fr>
* Port implementation is different: A port contains now its
input and output handler. String ports have been changed accordingly.
Sat Jun 1 21:23:01 1996 Erick Gallesio <eg@unice.fr>
* STk works on Win32: However, there are a lot of minor
things which are not correct (fonts, cursors). It seems that
most of this small problems are already resolved with Tk 4.1
(the official one). OK, start to port from Tk4.1a2 to Tk 4.1.
The main probleme will very probably be with the event loop.
Mon May 27 10:42:58 1996 Erick Gallesio <eg@unice.fr>
* Renaming files in STklos/Tk and STklos/Tk/Composite: they have now
a .stklos suffix (rather than .stk), because Win32 filenames are not
really case sensitives.
Sat May 11 08:33:22 1996 Erick Gallesio <eg@unice.fr>
* Integration of code modification for WIN32 port (snow only)
Fri Apr 26 09:26:10 1996 Erick Gallesio <eg@unice.fr>
* Src/primitives.c:
* Src/gc.c:
* Src/tcl-lib.c: Widgets don't capture anymore the environment. This
was necessary before release 3.0, but useless now. As a matter of
fact, widget-environment primitive has also been suppressed. Since it
was never documented, I doubt that someone will cry for it.
* Src/cont.c: Bug: Changed "#ifdef sun" by "#ifdef sparc" for
flushing the registers window Useful for Sun3 (bug signaled
by Michael A. Patton <MAP@BBN.com>)
* Lib/menu.stk: Tk:option-menu: function added (identical to the
Tcl one)
Thu Apr 25 23:10:37 1996 Erick Gallesio <eg@unice.fr>
* Tk/generic/tkMenu.c: Bug correction: tearoffmenucommand was not
defined as a closure.
Wed Apr 24 16:21:42 1996 Erick Gallesio <eg@unice.fr>
* Src/stklos.c: New protocol around gf: the following methods are now
called when an error occur with a gf call:
* no-next-method ((gf <generic>) args) as CLOS
* no-applicable-method ((gf <generic>) args) as CLOS
* no-method ((gf <generic>) args) when calling gf
without method
Tue Apr 23 23:02:26 1996 Erick Gallesio <eg@unice.fr>
* STklos/stklos.stk: New protocol for calling standard generic
functions. This protocol is not used for real <generic> function (in
this case we use a completly C hard-coded protocol). When a subclass
of <generic> is applied, the interpreter uses the new protocol instead
of the C one. This "opens" the generic function mechanism:
- special generic function can easily coded in Scheme (but
they will be slow)
- standard generic functions are as fast as possible.
This protocol provides the following generic functions:
* apply-generic ((gf <generic>) args)
* sort-applicable-methods ((gf <generic>) methods args)
* method-more-specific? ((m1 <method>) (m2 <method>) targs)
Mon Apr 22 23:50:18 1996 Erick Gallesio <eg@unice.fr>
* Src/boolean.c:
* Src/proc.c:
* Src/print.c:
* Src/gc.c:
* Src/stklos.c:
* Src/eval.c: STklos integration. Generic functions are recognized now
by the interpreter as standard STk objects (i.e. stklos is no more a
dynamically loadable extension). This integration provides:
- faster gf (the old way to implement gf is very general and
is not efficient (each call to a generic function implied
to search the way to apply the generic function in a table).
- gf are now properly tail recursive.
Fri Apr 19 23:53:32 1996 Erick Gallesio <eg@unice.fr>
* Src/print.c: Change -- address printing: the "#p" is no more used
when displaying an address. The #p is kept for Tk (of course) and
when using write.
Sun Apr 14 19:05:50 1996 Erick Gallesio <eg@unice.fr>
* Demos/compo-demo.stklos: New compo-demo for <Multiple-window>
* STklos/Tk/Composite/Multiwin.stk: 2 new composite widgets:
<Multiple-window>: a window which can contain several windows
<Inner-window> : a window embedded in a <Multiple-window>
The look is very similar to the Windows 95 explorer.
Sat Apr 13 21:58:18 1996 Erick Gallesio <eg@unice.fr>
* Tk/generic/tkEvent.c (Tk_AfterCmd): Bug correction for after idle
Sun Mar 31 22:38:54 1996 Erick Gallesio <eg@unice.fr>
* Src/unix.c: New primitive: setenv!
Fri Mar 29 15:06:46 1996 Erick Gallesio <eg@unice.fr>
* Src/gc.c (allocate_new_heap): Don't use must_malloc here since it
can conduct to call GC when allocating large heaps (typically with
large -cells xxx).
Mon Mar 25 14:20:21 1996 Erick Gallesio <eg@unice.fr>
* STklos/Tk/Canvas.stk: bind-for-dragging: bug correction end
enhancement. You can now specify a :before-motion and :after-motion
scripts. The old :motion is always accepted
(it's equivalent to :after-motion). If the :before-motion closure
returns #f, the object is not displaced and the :after-motion closure
is not applied.
Mon Feb 26 16:11:30 1996 Erick Gallesio <eg@unice.fr>
* STklos/stklos.stk: Two new methods are defined in STklos:
object-eqv? and object-equal?. They are called when doing an eqv? or
an equal? on STklos instance. These methods, which can of course be
specialized, return #f.
* Src/boolean.c: Extended types can now have a compare function which
is called when eqv? or equal? is called. This function is called when
one of the arguments of eq*? is of an extended type. See the document
on Extending STk for details.
Sat Feb 24 01:47:06 1996 Erick Gallesio <eg@unice.fr>
* Port of STk on Tk4.1a2.
This should simplify the port on Windows.
Mon Feb 19 17:19:49 1996 Erick Gallesio <eg@unice.fr>
* Src/toplevel.c (repl_driver): STk_interactivep was not correctly
initialized. This seem to be a regression (or a quirk in the home &
work files)
Fri Feb 16 14:49:48 1996 Erick Gallesio <eg@unice.fr>
* Src/number.c (do_integer_division): Correction of a bug signalled by
Raymond Toy <toy@rtp.ericsson.se>. Integer division of bignums was
buggy (aka Pentium symptom (except that it was always erroneous)).
Mon Feb 12 00:03:55 1996 Erick Gallesio <eg@unice.fr>
* Extensions/pixmap.c: Pixmap implementation uses now the file
tixImgXpm.c from the Tix Library (Author: Ioi Kim Lam). This
implementation doesn't need the Xpm library (which is difficult to
locate automatically with configure script and which has several
version with compatibily problems).
Wed Jan 24 11:52:49 1996 Erick Gallesio <eg@unice.fr>
* Src/print.c (STk_print): Bug correction. Print of special char in
Strings was buggy. Thanks Drew.Whitehouse@anu.edu.au for signalling
it. have also added \v and \a that I have forgot.
* STklos/Tk/Composite/Scrollcanvas.stk: Correcting a small typo error
signaled by Ralf Berger <Ralf.Berger@ipk.fhg.de>.
Sun Jan 21 23:57:37 1996 Erick Gallesio <eg@unice.fr>
* STk-3.0 (official) release (aka known as 3.0b2 since I have forgot to
set the correct version name.
Sun Dec 10 21:37:17 1995 Erick Gallesio <eg@biot.unice.fr (Erick Gallesio)>
* Src/promise.c (STk_force):
Bug correction for recursive expression in a force. It is now conform
to R4RS.
(define c #f)
(define p (delay (if c 100 (begin (set! c #t) (+ (force p) 1)))))
returns now the value 100 (and not 101).
This bug was raised with test.scm.
*******************
Changelog was not maintained for a while. I will try to update
it later. Sorry.

Sun Jul 16 10:30:26 1995 Erick Gallesio <eg@unice.fr>
* Snow/run-snow.in:
* Src/run-stk.in: I have changed the machine determination scheme
to avoid problems on Sun (sun4m sun4 sun4c... are all the same, at
least for STk). For Linux, there is no more differerence between
the Intel rocessor used for compiling STk (i{345}86 are all the same).
* Src/dynload.c:
* Src/configure.in:
* Src/Makefile.in:
* configure.in:
* Makefile.in: Support for ELF format under Linux. Thanks to
Johann Friedrich Heinrichmeyer and <jsc2mit.edu>

stdin.
* Src/stk.h:
* Src/toplevel.c:
* Src/argv.c: New option: -interactive to force the
interpreter to be interactive, even if it doesn't seem to
be. This is useful when using STk under Emacs.
When STk is interactive, stdout and stderr are now unbuffered.
* Src/port.c (STk_init_standard_ports): line buffering of Stderr has been
deleted. Everything is done now in toplevel.c (depends on the
-interactive flag
* Lib/regexp.stk: Bug correction in regexp-replace-all when replacing
string appears in the string to replace. Correction is due to
Sean Slattery <jslttery@GS148.SP.CS.CMU.EDU>
Wed Jul 12 09:57:10 1995 Erick Gallesio <eg@unice.fr (Erick Gallesio)>
* Src/syntax.c (syntax_let_family): Don't signal an error if a
symbol is defined twice in a let*. Formal semantics given in R4RS
allows it (whereas textual explanation seems to forbid it.
Problem was found by Brent Knight <knight@CS.Cornell.EDU>.
* Src/port.c: New definition of macro READ_DATA_PENDING for
ELF compiling. Thanks to Jin S. Choi <jsc@tabitha.atype.com>
for the bug correction.
* Lib/init.stk: Macros are now defined in the global environment.
This avoids problems when some primitives procedure are redefined.
All the primitive should be protected for those redefinitions.
* Lib/Makefile (install): prolog.ps is now placed in the good directory
* Tk/tkCanvas.c (CanvasWidgetCmd): Correction of a bug signaled by
Johann Friedrich Heinrichmeyer. The result of the poscript command
must be "stringified".
Tue Jul 11 21:16:17 1995 Erick Gallesio <eg@unice.fr (Erick Gallesio)>
* STklos/Tk/Canvitem.stk (initialize-item): INCOMPATIBLE CHANGE
<Text> in canvas has been renamed in <Canvas-text> to avoid a conflict
when using both cnavases and texts widgets.
Demos have been modified to take this modification into account
* STklos/Tk/Composite/Scrollcanvas.stk (<Scroll-canvas>):
* STklos/Tk/Composite/Scrollbox.stk (<Scroll-listbox>): Bug correction in
background propagation. (Bug signaled by H. J. Stein)
Tue Jul 11 16:31:44 1995 Erick Gallesio <eg@kaolin.unice.fr (Erick Gallesio)>
* Correction of several bugs signaled by Eric Ostrom on text widget
Fri Jul 7 23:27:17 1995 Erick Gallesio <eg@unice.fr (Erick Gallesio)>
* Tk/tkWindow.c (Tk_CreateMainWindow):
* Src/toplevel.c (init_interpreter): Init system path from
STK_LIBRARY shell variable. This variable MUST be initialized now
(this is done in the stk or snow scripts). This allows us to make
binaries which are independant of their location. This will permit
to distribute binaries on kaolin.
* Src/hash.c: Modification of the hash table module to take into
account an optional parameter which specifies the comparison function.
This permits to have equal? eqv? eq? or string? hash tables for instance
Tue Jul 4 14:04:49 1995 Erick Gallesio <eg@unice.fr (Erick Gallesio)>
* Src/port.c:
* Src/sport.c: Minor code cleaning (using STk_is_thunk)
Fri Jun 23 22:27:26 1995 Erick Gallesio (eg@unice.fr)
* STklos/Tk/Composite/Scrolltext.stk (<Scroll-text>): bug correction
in background propagation
Mon Jun 5 18:03:47 1995 Erick Gallesio (eg@kaolin.unice.fr)
* STk-2.1.7 release
* Extensions/posix.c: An extension for using Posix primitives in
Scheme. Far from complete. This is just a start. Any help on this
point would be appreciated.
* Doc/Extension/Extending.tex: A new version which is more (but not
totally :-<) complete.
* Extensions/stack.c: a new file used for illustating the document
"Extending the STk interpreter"
* Demos/amib.stklos: A new version of the interfac builder which
is usable now. This version handle the packer and the placer.
* STklos/Tk/Composite/Multipaned.stk (initialize-composite-widget):
Addition of the Multipaned composite widget. Thanks to Harvey J. Stein,
for his modifications.
Sat Jun 3 00:44:53 1995 Erick Gallesio (eg@unice.fr)
* Lib/init.stk:
* Src/syntax.c: Rewritting of "while" and "unless" in C
* A new type: tc_ssubr. This type is temporary and will change in
the next release. This type correspond to all n-ary functions of
number.c. Correction of an ENNORMEOUS bug: There was a double
evaluation when fsubr where called by apply!!!. Fsubr cannot be
applyed now (ssubr are the only procedure with non evaluated
parameter which can be appyed.
* Src/proc.c (STk_procedurep): (Procedure? a-tk-command) => #t now
* Lib/inspect-misc.stk (inspect::typeof obj): correction of a bug
introcuced in the inspector by previous modification
Fri Jun 2 00:07:20 1995 Erick Gallesio (eg@unice.fr)
* Src/gf.c (find_method): Code cleaning.
Thu Jun 1 19:29:39 1995 Erick Gallesio (eg@unice.fr)
* Src/port.c (do_load): I have added a comment when a file has
finished to be loaded, as suggested by David Fox.
* Src/gc.c (gc_sweep): GC calls now Tcl_DeleteCommand when a new
command is deleted. See below ...
* Src/tcl-lib.c: Modifications of {Create,Delete}Interp and
{Create,Delete}Command to really execute the detete code of a
Tk-command. This seems to be useful only for the send command
annd "." command (but would also be probably useful for future
tcl extensions). The "send" associated delete proc permits to
unregister the interpreter from the X server (bug signalled by
Sean Slattery slttery@GS148.SP.CS.CMU.EDU and that I have never
seen !!!!).
Mon May 29 17:04:53 1995 Erick Gallesio (eg@unice.fr)
* STklos/Tk/Message.stk (<Message>): Deleteing the class
<Tk-sizeable> from <Message> class. This was erroneous.
Fri May 26 23:52:40 1995 Erick Gallesio (eg@unice.fr)
* STklos/Tk/Toplevel.stk (<Toplevel>): Adding the :init-keyword
for class and display slots. This modification was necessary for
the new AMIB. Min-size and max-size slots contain now a string
and class and display slots contain a string (it was a symbol)
* STklos/Tk/Frame.stk (<Frame>): Adding the :init-keyword for
class slot Class slot contains a string (it was a symbol)
Fri May 19 22:44:59 1995 Erick Gallesio (eg@unice.fr)
* Src/sport.c (STk_get_output_string): Correction of a bug
signalled by Fritz.Heinrichmeyer@fernuni-hagen.de
Wed May 3 12:59:24 1995 Erick Gallesio (eg@unice.fr)
* STklos/Tk/Composite/Paned.stk (motion-grip): Applying the patch
of Harvey J. Stein <hjstein@MATH.HUJI.AC.IL> which constraints
the grip ]0..1[ This permits to avoid its disappearance.
Tue May 2 00:05:55 1995 Erick Gallesio (eg@unice.fr)
* STklos/Tk/Tk-methods.stk: This file is always loaded now (it was
loaded only when Tk was initialized before). Read the comment in
this file when re-using STk images. *top-root* initialization is
in Tk-methods.stk rather than Toplevel.stk now.
* Lib/tk-init.stk (Tk:initialized?): a new variable which is set
to #t when Tk is fully initialized
Mon May 1 16:55:18 1995 Erick Gallesio (eg@unice.fr)
* Src/stklos.c (display_instance):
* Src/error.c (STk_err):
* Src/eval.c (STk_show_eval_stack):
* Src/port.c (STk_write):
* Src/tk-glue.c (STk_convert_for_tk):
* Src/toplevel.c (repl_loop):
* Src/extend.c (internal_display):
* Src/print.c (STk_print): All those files have been modified for
giving the port (a SCM object) to the procedure which do a print
rather than a FILE *, which is more general. This modification is
necessary for permitting a real display_object in extension. STklos
uses this for the {write,display,tk-write}-object methods.
Tue Apr 25 14:57:48 1995 Erick Gallesio (eg@kaolin.unice.fr)
* Src/number.c (STk_gcd): Bug correction in lcm, gcd, min and max (arguments
were evaluated several times!!!!).
Tue Apr 18 14:55:23 1995 Erick Gallesio (eg@kaolin.unice.fr)
* STklos/Tk/Composite/Scrolltext.stk: New file. It implements what
you think it should!!
* STklos/Tk/Composite/Scrollcanvas.stk: New file. It implements
what you think it should!!
* STklos/Tk/Composite/Scrollbox.stk (<Scroll-listbox>): Scroll
listbox accept now horizontal scrollbar.
Sat Apr 15 15:40:40 1995 Erick Gallesio (eg@unice.fr)
* Tk/tkListbox.c (ListboxWidgetCmd): Correction of an old old bug:
Getting an element of listbox always retusrns a string. However,
this modification breaks down the inspector.... (it is time to
rewrite it....)
Fri Apr 14 23:32:42 1995 Erick Gallesio (eg@unice.fr)
* Src/number.c (STk_round): Bug correction. (Round x) must returns
the closest integer to x, rounding to even when x is halfway
between two integers.
Fri Mar 31 00:15:36 1995 Erick Gallesio (eg@unice.fr)
* Src/configure.in: Adding test for the existence of the pid_t
type. This is needed for porting STk on Sony WS (Sony NEWS,
NEWSOS 4.2R) Thanks to Nobuyuki Hikichi <hikichi@sra.co.jp>
* Lib/init.stk (random): have been extended to allow the result to
be a bignum. Here again, thanks to Nobuyuki Hikichi
<hikichi@sra.co.jp>
Sat Mar 25 23:33:54 1995 Erick Gallesio (eg@unice.fr)
* STk/read.c: Modification of the reader to remember current
filename and line counters. This eases debugging since error
messages can display those informations.
Thu Mar 16 15:32:59 1995 Erick Gallesio (eg@kaolin.unice.fr)
* Src/extend.c (STk_define_C_variable): New function. This
function permit to establish a link between a C variable and a
Scheme one. Once this link is established, every reading of the
variable will call a getter function and every write will call the
setter function. No data is used in the Scheme space, variable
value is a C data.
Wed Mar 15 17:21:40 1995 Erick Gallesio (eg@kaolin.unice.fr)
* New primitive type: C-pointer. This is a Scheme type to wrap a C
pointer. It greatly eases communication with C.
* Src/extend.c: New file. This file contains all the code for
extensions and C pointers. It contains a ot of code from old
dynload.c. File dynload.c contains now only the function which do
dynamic loadind (and which is very sytem dependant.
Tue Mar 14 13:30:11 1995 Erick Gallesio (eg@kaolin.unice.fr)
* Src/slib.c (STk_internal_eval_string): Bug correction. The error
context was false.
Fri Mar 10 15:55:47 1995 Erick Gallesio (eg@kaolin.unice.fr)
* Src/userinit.c (STk_user_cleanup): STk_user_cleanup has been added.
* Src/port.c (STk_init_standard_ports): Error file is now line
buffered. This gives better performances when used under emacs.
Thu Mar 9 12:49:43 1995 Erick Gallesio (eg@kaolin.unice.fr)
* Added support for dynamic loading under Linux (with DLD). Code
is inspired from a contribution of Patrick Nguyen
(pnguyen@elde.epfl.ch)
Sun Mar 5 16:06:11 1995 Erick Gallesio (eg@unice.fr)
* Src/port.c (STk_char_readyp): Added support for char-ready. Code
should not be very portable...
Sat Feb 25 11:51:45 1995 Erick Gallesio (eg@unice.fr)
* Src/slib.c (STk_get_internal_info): Bug correction: the result
was completely erroneous. Is it possible that I have tested this
function without having seen this????
* Dynamic loading should work for OSF1 (Thanks to Erik Ostrom
<eostrom@radon.ccs.neu.edu>)
Sun Feb 12 18:00:15 1995 Erick Gallesio (eg@unice.fr)
* 2.1.6 release
Sat Feb 11 23:23:15 1995 Erick Gallesio (eg@unice.fr)
* Src/env.c (STk_parent_environment): New function. It was time to
write it...
* Src/port.c (STk_error): Set context to ERR_OK but keep the bit
indicating if error must be caught or not.
* New version of blt for STk. Some minor changes for compiling it
with new C conventions.
Thu Feb 9 23:21:52 1995 Erick Gallesio (eg@unice.fr)
* STklos/Tk/Basics.stk: Tk::find-option is defined as autoload to
permit image creation.
* STklos/Tk/Toplevel.stk: Definition of *top-root* is deferred
until first <Toplevel> creation (to allow image creation)
* STklos/Tk/Tk-methods.stk: New file. This file contains the
redefinition of Tk commands as methods. This file is loaded when
the first Tk object is really created. Deferring the loading of
this file permits to make images of interpreters containing Tk
classes.
Thu Feb 2 23:15:15 1995 Erick Gallesio (eg@biot)
* Src/unix.c (absolute): Bug correction for file name with mutiple
dots such as "...1../2" which were improperly expanded
* Src: Yeaaah. All the symbols defined by STk are now prefixed by
"STk_". It tooks me some days to obtain this. I take this
occasion to pass through the code and try to ameliorate things
rather than using brute force.
Wed Feb 1 02:17:12 1995 Erick Gallesio (eg@biot)
* Socket support has been rewritten. It is now configured by
default. New model seems more simple (at least for me) and more
coherent with the process extension.
Tue Jan 31 10:30:29 1995 Erick Gallesio (eg@kaolin.unice.fr)
* Modification of all Makefile to use $(MAKE) rather than make as
suggested by Christian Lynbech <lynbech@daimi.aau.dk>
Mon Jan 30 15:22:06 1995 Erick Gallesio (eg@kaolin.unice.fr)
* Tk/tkConfig.h: Modifications for HPUX.
Sun Jan 29 15:11:06 1995 Erick Gallesio (eg@biot)
* Src/process.c: Completely cleaned up. Table of processes is
managed by the SIGCHLD signal if it exists. On machines without
job control, process management is done by hand. Some new function
have been added (suggested on the mailing list by Giorgio Cesana
<cesana@venus.agcis.st.it>): process-exit-status, process-stop,
process-continue, process-send-signal.
(run_process): A new option: ":host" which permits to execute the command
on a distant host.
Mon Jan 23 12:07:23 1995 Erick Gallesio (eg@kaolin.unice.fr)
* Src/tk-main.c (Tk_main): adding code for managing argument line
-geometry option. It was missing....
* Src/stklos.c (make_primitive_classes): Adding the new primitive
class <list> which is the ancestor of <pair> and <null>. Suggested
by Harvey J. Stein (hjstein@math.huji.ac.il)
Sun Jan 22 18:12:02 1995 Erick Gallesio (eg@biot)
* Demos/inspector.stk: A small demo, for showing usage of the
inspector with Tk object. A very simple thing but this seems to be
rather unknown.
Sat Jan 21 23:01:15 1995 Erick Gallesio (eg@biot)
* Src/read.c (lreadr): Cosmetic changes. Using the sym_XXX
variables instead of interning them at each time.
* Src/gc.c (allocate_new_heap): Setting of the field gc_mark to 0
for all new allocated cell. Thanks to Chet Murphy
<murthy@CS.Cornell.EDU> for this bug correction.
* Src/toplevel.c (init_interpreter): Bug correction: sym_unquote
was gc protected twice whereas sym_unquote_splicing was not. A
cut/paste error which took 2 days to debug :-(
Mon Jan 9 12:06:08 1995 Erick Gallesio (eg@kaolin.unice.fr)
* Configure and Mafefile files modifications to allow dynamic
loading under Irix 5.3. Thanks to Michael Tiemann
<tiemann@cygnus.com> for the patches.
Sun Jan 1 21:10:45 1995 Erick Gallesio (eg@biot)
* One important thing :-) Adding 1995 in all the files which
contains a copyright notice. This is the good day for doing that
(an only that!).
Fri Dec 30 17:56:40 1994 Erick Gallesio (eg@biot)
* New organization of Tcl files. All The Tcl files have been
updated to release 7.4b1 (the Tcl release that comes with Tk
4.0b1). The file Src/tcl-util.c has shrink a lot and most of it
is now in Tcl/tlUtil.c (in fact a copy of the original file with
some #ifdefs). This last change is break the previous philosophy
of libtcl.a (a library of Tcl file *unmodified*) but changes are
minor and I hope that it will ease the port to new version of
Tcl/Tk which semble very instable at this time.
Wed Dec 28 18:14:22 1994 Erick Gallesio (eg@biot)
* Lib/error.stk (report-error): Modification of error message format
* Src/primitives.c: Deleting the definition of the "lindex"
primitive which doesn't serve anymore.
Tue Dec 20 12:02:00 1994 Erick Gallesio (eg@kaolin.unice.fr)
* Src/syntax.c (syntax_define): "Bug" correction: When using a
local "define", There was a duplication of the binding if the
symbol was already defined in the out most environment. Since the
new binding was placed before the older one, good value was
found. However, it makes environment bigger than necessary
(and strange result when using environment->list).
* Src/env.c (value_in_env): New function. It returns the value of
var in given env. Search is done only at out most level. This
function is an utility function for local "define".
Mon Dec 19 12:08:31 1994 Erick Gallesio (eg@kaolin.unice.fr)
* Src/stk.h (MAX_CHAR_CODE): Correct value is 255 (it was 256)
Fri Dec 16 16:06:57 1994 Erick Gallesio (eg@kaolin.unice.fr)
* STk 2.1.5 release
Fri Dec 16 13:56:25 1994 Erick Gallesio (eg@kaolin.unice.fr)
* Src/dynload.c: Adding support for HPUX (thanks to ipankar Gupta
<dg@hplb.hpl.hp.com>)
Fri Dec 9 22:15:34 1994 Erick Gallesio (eg@biot)
* Snow/run-snow.in: There is now a new interpreter, called snow
(for Scheme NO Window), which is the STk interpreter without Tk
support. This interpreter is an independant executable. It can be
called with the snow shell-script or by unsetting the DISPLAY
variable.
Thu Dec 8 22:47:44 1994 Erick Gallesio (eg@biot)
* Makefile.in: Modifications of all configure.in and Makefile.in.
Now we can
- share versions of STk between different architectures
- have several versions of STk installed on the same machine
Wed Dec 7 21:46:44 1994 Erick Gallesio (eg@biot)
* Src/dynload.c (load_object_file): Adding dynamic loading support
for NetBSD-1.0 (i386-port). Thanks to Franke Ruediger
(Ruediger.Franke@rz.tu-ilmenau.de) for the patch.
Tue Dec 6 00:26:48 1994 Erick Gallesio (eg@biot)
* Src/tk-glue.c (execute_Tk_lib_cmd): GC bug correction. There was a
bug when a GC occured during the creation of the argv array of a Tk
command. This bug occured on Linux with -O2; Correcting it doesn't arrange
things==> Usage of an equivalent code. Thanks to H. Stein for signaling this bug.
Sat Nov 26 10:46:58 1994 Erick Gallesio (eg@biot)
* Src/stklos.c: Changing all the "class" variables by "clath" for
C++ users
* Src/port.c (loadfile): All the code for loading file is now
written in C and things are more "orthogonal". New variable
defined: *load-suffixes*.
* Src/toplevel.c (repl_driver): Move of user init initialisation
so taht they are taken into account in case of a "stk -f" (thanks
to Brian Webb webbb@aies.tucson.saic.com)
Wed Nov 9 13:54:34 1994 Erick Gallesio (eg@kaolin.unice.fr)
* STk-2.1.4 release
Thu Nov 3 23:20:06 1994 Erick Gallesio (eg@biot)
* A New datatype: regular expressions. They are defined in a
dynamic loadable file (for the regexp compiler and the apply
function) and in a Scheme file
(mainly for the regexp-replace[-all] procedures
Wed Nov 2 16:49:07 1994 Erick Gallesio (eg@kaolin.unice.fr)
* file-is-xxx? and file-exists? are now written in C
* Elimination of %file and %string Tcl command. Those commands
were used behind the scene to avoid some rewriting. No code in the
distribution should use them. This conduct to the defineition of
two new primitives string-index and file-is-executable? (which was
forgotten in previous releases).
Mon Oct 31 11:04:27 1994 Erick Gallesio (eg@biot)
* Src/hash.c (hash_table_stats): Circumvent a bug in Tcl code on
empty hash tables (see comment in source file)
Fri Oct 28 14:23:36 1994 Erick Gallesio (eg@biot)
* STklos/Tk/Toplevel.stk (<Toplevel>): All the "wm" Tk-command
options are now available through Toplevel slot accesses (Idea
from Rob Deline) A New global variable: *top-root*: This is a
toplevel which contains the *root* window. Changing the name of
the root window can now be done by
(set! (title *top-root*) "New title")
Tue Oct 18 14:42:55 1994 Erick Gallesio (eg@kaolin.unice.fr)
* Src/number.c (lround): Rewritten to avoid the use of the rint(3)
function which does'nt seems to exist on some systems (SCO and
some HP at least)
Mon Oct 17 18:29:31 1994 Erick Gallesio (eg@biot)
* Lib/editor.stk (stk:all-fonts): Various font specifications
changes (those which where used in all the Lib directory where not
portable.
Mon Oct 17 11:38:17 1994 Erick Gallesio (eg@kaolin.unice.fr)
* Src/slib.c (lrandom): Bug correction (bignum where not allowed
as parameter => (random(random 10)) was invalid since result of
random is always a bignum
(bug signaled by Markus Armbruster <armbru@pond.sub.org>)
Fri Oct 14 09:02:12 1994 Erick Gallesio (eg@kaolin.unice.fr)
* New procedure: run-process which permit to run a process with
redirection off the stdin, stdout and stderr. The code is a
rewriting of the Alexander Taranov, Grygory Niconov and David
Tolpin contribution.
Thu Oct 13 14:56:05 1994 Erick Gallesio (eg@kaolin.unice.fr)
* Src/number.c: Add a rint compatible function for systems which
desn't provide one (SCO apparently -- signaled by
markd@grizzly.com)
Wed Oct 12 15:12:51 1994 Erick Gallesio (eg@kaolin.unice.fr)
* New functions for port manipulation (port->string
port->string-list ....) With those function, it is easy to
write a Tcl-like exec. All those function are written in
Scheme.
Tue Oct 11 15:53:49 1994 Erick Gallesio (eg@kaolin.unice.fr)
* Src/slib.c (set_random_seed): modified to allow bignums for the seed.
Mon Oct 10 14:16:52 1994 Erick Gallesio (eg@kaolin.unice.fr)
* Minor modifications to allow a better compilation on some C and C++
compilers.
Sun Oct 9 18:19:01 1994 Erick Gallesio (eg@biot)
* Bug correction: the eval_stack (which serves ONLY for displaying
context upon error was not corectly managed on "tail recursion
elimination". This leads to memory consumption on infinites loops.
Tue Sep 27 11:46:01 1994 Erick Gallesio (eg@kaolin.unice.fr)
* STklos/tk-classes.stk: Creation of a new file which define a set
of autoloads. Those autoload permits to avoid to use a long list
of require at the beginning of programs
* Src/port.c (do_autoload): Adding support for autoload in C. Now,
any kind of symbol can be autoloaded.
Thu Sep 15 16:36:01 1994 Erick Gallesio (eg@kaolin.unice.fr)
* 2.1.3 Release
Wed Sep 14 18:52:14 1994 Erick Gallesio (eg@kaolin.unice.fr)
* Src/stklos.c (make_instance): GC bug correction in a critical
section of code.
* Src/macros.c (lmacro): GC bug correction in a critical section
of code.
* Src/symbol.c (intern): modification of a critical section of
code a GC could occur between the hash table entry creation and
the end of its initialization. Correction of the same kind of
problem in keyword.c. Bug discovered by Rob Deline.
* Src/stklos.c (modify_instance): Bug correction (change-class
make a twist between old and new instance) ==> following GC free
the bad instance data !!
Fri Sep 9 13:40:12 1994 Erick Gallesio (eg@kaolin.unice.fr)
* Packing of the STk2.1.2 release
Thu Sep 8 09:27:16 1994 Erick Gallesio (eg@kaolin.unice.fr)
* STklos/stklos.c: Definition of a slot_set_if_unbound which only
affect a slot if needed. This function is used in the slots
initialization process. Now, things are corrects when a slot
:initform is overloaded by inheritance or when initialization is
done in an initialize followed by a next-method
(i.e. it's the user value which is taken instead of the default one).
* Src/gc.h: re-integretate gc_protect (can be useful for extension
writers)
* After 3 days continuations are tail recursive..... I thought I
will become crazy before I found the little typing mistake (a
lsubr instaed of a tsubr in primitives.c) which makes things
weird.
Mon Sep 5 18:37:16 1994 Erick Gallesio (eg@kaolin.unice.fr)
* Symbols and keywords use now Tcl Hash table (which grow
dynamically). Keywords share now memory. This reduces drastically
space occupation. (Old symbol table uses conses, and keywords
where not shared). Unused symbols can be GCed now.
* Change class bug correction (Thanks to Rob Deline).
Fri Sep 2 11:41:04 1994 Erick Gallesio (eg@kaolin.unice.fr)
* -image can be specified needs not anymore to be the first
argument of the command line.
* Src/argv.c: "-cells" can be specified when calling stk. This
give the amount of cells created upon init.
Wed Aug 31 14:17:44 1994 Erick Gallesio (eg@kaolin.unice.fr)
* Src/argv.h (save_unix_args_and_environment): moved to
argv.c. This new file contains all the argc/argv/env stuff. STk
doesn't rely anymore on Tk code for parsing command line
arguments. This permits to have a arguments processing even if not
compiled with -DUSE_TK.
Tue Aug 30 13:39:53 1994 Erick Gallesio (eg@kaolin.unice.fr)
* Tk/tkArgv.c (Tk_ParseArgv):
* Src/gc.c (init_gc): GC complete revision: Now we have a set of
heaps and a new heap is allocated as soon as the global space is
"nearly" filled (I have fixed nearly to 75%). User can maually
grow the heap by using extend-heap. There are time statitics now
indicating how much time is spent in GC.
Mon Aug 29 12:35:05 1994 Erick Gallesio (eg@kaolin.unice.fr)
* Src/cont.c (throw): bug correction in
continuations. Specifically, the gc_mark phase for the
continuation blocks may fail because the stack starting and ending
addresses used in the code are both (char *), not (SCM *),
aligned, and the stack is copied in bytes, not in SCMs. on char *
rather than SCM. This bug was discoverred by Felix Wu
(wu@cadence.com)
* Adding SLIB support (i.e. I have written the STk.init
file). Some modifications in stk.init were needed (accepting the
".scm" suffix mainly)
* Src/macros.c (expand): Cleanup in macros. We have now
macro-expand and macro-expand-1
Thu Aug 25 15:59:33 1994 Erick Gallesio (eg@kaolin.unice.fr)
* Src/number.c (do_integer_division): bug correction for
modulo. The fix is due to kerch@parc.xerox.com.
Wed Aug 24 12:02:41 1994 Erick Gallesio (eg@kaolin.unice.fr)
* Src/number.c (integerp): Bug correction. integer? must returns
#t even if the value is an inexact integer.
* port.c: - modification to allow close-port on string-port
- if the first char of a filename is a pipe ("|") character,
usage of popen instead of fopen. This permits to define
"pipe ports" very easily as in Tcl.
* Integration of the Suresh Srinivas STk-wtour demo to the
Contrib. Some minor bugs have been fixed and some new lessons have
been added. Hierarchy was modified to fit to the contrib
directory.
Tue Aug 23 17:16:34 1994 Erick Gallesio (eg@kaolin.unice.fr)
* Definition of a file compatibility file which assume compatibily
among versions. When this file is loaded, a message will be
printed, saying that you have to upgrade your source.
* Adding support for Text in STklos Definition of a new version of
the STF format (0.2) which permits to load and save files with
their enhancment (font, color, ...). Now, tags can be dynamically
created (instead of choosen in a fixed list). A compatibility
mode is provided (see above)
