    * 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  <[e-mail]>

    * 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  <[e-mail]>

    * 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  <[e-mail]>

    * 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  <[e-mail]>

    * 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  <[e-mail]>

    * 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  <[e-mail]>

    * 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  <[e-mail]>

    * 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  <[e-mail]>

    * 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  <[e-mail]>

    * 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  <[e-mail]>

    * Integration of code modification for WIN32 port (snow only)

Fri Apr 26 09:26:10 1996  Erick Gallesio  <[e-mail]>

    * 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 <[e-mail]>)

    * Lib/menu.stk: Tk:option-menu: function added (identical to the
    Tcl one)

Thu Apr 25 23:10:37 1996  Erick Gallesio  <[e-mail]>

    * Tk/generic/tkMenu.c: Bug correction: tearoffmenucommand was not
    defined as a closure.

Wed Apr 24 16:21:42 1996  Erick Gallesio  <[e-mail]>

      * 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  <[e-mail]>

    * 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  <[e-mail]>

    * 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  <[e-mail]>

    * 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  <[e-mail]>

    * 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  <[e-mail]>

    * Tk/generic/tkEvent.c (Tk_AfterCmd): Bug correction for after idle

Sun Mar 31 22:38:54 1996  Erick Gallesio  <[e-mail]>

    * Src/unix.c: New primitive: setenv!

Fri Mar 29 15:06:46 1996  Erick Gallesio  <[e-mail]>

    * 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  <[e-mail]>

    * 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  <[e-mail]>

    * 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  <[e-mail]>

    * Port of STk on Tk4.1a2.
    This should simplify the port on Windows.

Mon Feb 19 17:19:49 1996  Erick Gallesio  <[e-mail]>

    * 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  <[e-mail]>

    * Src/number.c (do_integer_division): Correction of a bug signalled by
    Raymond Toy <[e-mail]>. Integer division of bignums was
    buggy (aka Pentium symptom (except that it was always erroneous)).

Mon Feb 12 00:03:55 1996  Erick Gallesio  <[e-mail]>

    * 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  <[e-mail]>

    * Src/print.c (STk_print): Bug correction. Print of special char in
    Strings was buggy.  Thanks [e-mail] 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 <[e-mail]>.

Sun Jan 21 23:57:37 1996 Erick Gallesio  <[e-mail]>

    * 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  <[e-mail] (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.

    * Starting STk 3.0 ....

Mon Jul 17 20:55:27 1995  Erick Gallesio  <[e-mail] (Erick Gallesio)>

    * 2.2 Release
    * Src/syntax.c (STk_syntax_begin): begin, and & or were not always
    tail recursives. This bug was detected (and corrected) by  Lars Thomas
    Hansen <[e-mail]>

Sun Jul 16 10:30:26 1995  Erick Gallesio  <[e-mail]>

    * 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>

    * Src/slib.c (STk_machine_type):
    * Src/toplevel.c (print_banner): MACH define has been changed by MACHINE
    to avoid problems with Mach systems.

    * Doc/Extension/Extending.tex: Adding documentation for Tcl widget
    integration

Thu Jul 13 09:04:54 1995  Erick Gallesio  <[e-mail]>

    * Doc/Reference/Appendix-D.tex: Description of Ilisp, CMU Scheme packages
    * Doc/Manual/stk.txt: New manual page. Manual page is now installed in
    $(prefix)/man/man1/stk.1

    * Src/error.c (STk_err): Don't print a line number when error comes from
    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 <[e-mail]>

Wed Jul 12 09:57:10 1995  Erick Gallesio  <[e-mail] (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 <[e-mail]>.

    * Src/port.c: New definition of macro READ_DATA_PENDING for
    ELF compiling. Thanks to Jin S. Choi <[e-mail]>
    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  <[e-mail] (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  <[e-mail] (Erick Gallesio)>

    * Correction of several bugs signaled by Eric Ostrom on text widget

Fri Jul  7 23:27:17 1995  Erick Gallesio  <[e-mail] (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  <[e-mail] (Erick Gallesio)>

    * Src/port.c:
    * Src/sport.c: Minor code cleaning (using STk_is_thunk)

Fri Jun 23 22:27:26 1995  Erick Gallesio  ([e-mail])

    * STklos/Tk/Composite/Scrolltext.stk (<Scroll-text>): bug correction
    in background propagation

Mon Jun  5 18:03:47 1995  Erick Gallesio  ([e-mail])

    * 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  ([e-mail])

    * 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  ([e-mail])

    * Src/gf.c (find_method): Code cleaning.

Thu Jun  1 19:29:39 1995  Erick Gallesio  ([e-mail])

    * 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 [e-mail] and that I have never
      seen !!!!).

Mon May 29 17:04:53 1995  Erick Gallesio  ([e-mail])

    * 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  ([e-mail])

    * 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  ([e-mail])

    * Src/sport.c (STk_get_output_string): Correction of a bug
      signalled by [e-mail]

Wed May  3 12:59:24 1995  Erick Gallesio  ([e-mail])

    * STklos/Tk/Composite/Paned.stk (motion-grip): Applying the patch
      of Harvey J. Stein <[e-mail]> which constraints
      the grip ]0..1[ This permits to avoid its disappearance.

Tue May  2 00:05:55 1995  Erick Gallesio  ([e-mail])

    * 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  ([e-mail])

    * 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  ([e-mail])

    * 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  ([e-mail])

    * 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  ([e-mail])

    * 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  ([e-mail])

    * 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  ([e-mail])

    * 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 <[e-mail]>

    * Lib/init.stk (random): have been extended to allow the result to
    be a bignum. Here again, thanks to Nobuyuki Hikichi
    <[e-mail]>

Sat Mar 25 23:33:54 1995  Erick Gallesio  ([e-mail])

    * 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  ([e-mail])

    * 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  ([e-mail])

    * 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  ([e-mail])

    * Src/slib.c (STk_internal_eval_string): Bug correction. The error
    context was false.

Fri Mar 10 15:55:47 1995  Erick Gallesio  ([e-mail])

    * 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  ([e-mail])

    * Added support for dynamic loading under Linux (with DLD). Code
    is inspired from a contribution of Patrick Nguyen
    ([e-mail])

Sun Mar  5 16:06:11 1995  Erick Gallesio  ([e-mail])

    * 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  ([e-mail])

    * 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
    <[e-mail]>)

Sun Feb 12 18:00:15 1995  Erick Gallesio  ([e-mail])

    * 2.1.6 release

Sat Feb 11 23:23:15 1995  Erick Gallesio  ([e-mail])

    * 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  ([e-mail])

    * 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  ([e-mail])

    * Modification of all Makefile to use $(MAKE) rather than make as
    suggested by Christian Lynbech <[e-mail]>

Mon Jan 30 15:22:06 1995  Erick Gallesio  ([e-mail])

    * 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
    <[e-mail]>): 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  ([e-mail])

    * 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 ([e-mail])

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
    <[e-mail]> 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  ([e-mail])

    * Configure and Mafefile files modifications to allow dynamic
    loading under Irix 5.3. Thanks to Michael Tiemann
    <[e-mail]> 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  ([e-mail])

    * 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  ([e-mail])

    * Src/stk.h (MAX_CHAR_CODE): Correct value is 255 (it was 256)

Fri Dec 16 16:06:57 1994  Erick Gallesio  ([e-mail])

    * STk 2.1.5 release

Fri Dec 16 13:56:25 1994  Erick Gallesio  ([e-mail])

    * Src/dynload.c: Adding support for HPUX (thanks to ipankar Gupta
    <[e-mail]>)


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
    ([e-mail]) 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 [e-mail])

Wed Nov  9 13:54:34 1994  Erick Gallesio  ([e-mail])

    * 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  ([e-mail])

    * 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  ([e-mail])

    * 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  ([e-mail])

    * 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 <[e-mail]>)

Fri Oct 14 09:02:12 1994  Erick Gallesio  ([e-mail])

    * 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  ([e-mail])

    * Src/number.c: Add a rint compatible function for systems which
    desn't provide one (SCO apparently -- signaled by
    [e-mail])

Wed Oct 12 15:12:51 1994  Erick Gallesio  ([e-mail])

    * 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  ([e-mail])

    * Src/slib.c (set_random_seed): modified to allow bignums for the seed.

Mon Oct 10 14:16:52 1994  Erick Gallesio  ([e-mail])

    * 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  ([e-mail])

    * 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  ([e-mail])

    * 2.1.3 Release

Wed Sep 14 18:52:14 1994  Erick Gallesio  ([e-mail])

    * 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  ([e-mail])

    * Packing of the STk2.1.2 release

Thu Sep  8 09:27:16 1994  Erick Gallesio  ([e-mail])

    * 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  ([e-mail])

    * 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  ([e-mail])

    * -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  ([e-mail])

    * 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  ([e-mail])

    * 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  ([e-mail])

    * 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
    ([e-mail])

    * 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  ([e-mail])

    * Src/number.c (do_integer_division): bug correction for
    modulo. The fix is due to [e-mail].

Wed Aug 24 12:02:41 1994  Erick Gallesio  ([e-mail])

    * 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  ([e-mail])

    * 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)
