09/26/96 Release 3.1.1
|
|
----------------------
|
|
|
|
This release is a bug correction release. It corrects a lot bugs.
|
|
A lot of theses bugs prevent to install it on some architectures.
|
|
Apart bugs:
|
|
|
|
- Version of Tk is now at Tk4.1p1 level (last stable version)
|
|
|
|
- a MS VC makefile is now provided for Win 32 thanks to
|
|
Caleb Deupree <cdeupree@erinet.com> (I have changed some things
|
|
from the Caleb file but cannot test them, I hope this is correct)
|
|
|
|
- Support for sockets on Win32 was done by Caleb Deupree on MS
|
|
VC. This should also work on BC++ but I'm not able to test it.
|
|
|
|
|
|
07/24/96 Release 3.1
|
|
--------------------
|
|
|
|
- Version of Tk is now at Tk4.1 level.
|
|
|
|
- STk run now on Win32!!!
|
|
Some details need a little more work (some oddities on file names
|
|
due to difference conventions between Unix and DOS, and things like
|
|
that). No socket support and no dynamic loading on Win32
|
|
|
|
- A complete documentation of STk widgets pages (both in nroff
|
|
and HTML format). The help command really allow you to browse
|
|
man pages now. Man pages are prefixed by "stk_" now to avoid confusion
|
|
with original Tk manual pages.
|
|
|
|
- STklos is now integrated to STk (it was dynamically loaded before).
|
|
This simplify its implementation and speed up generic functions:
|
|
o gf are now 2-4 time faster
|
|
o gf are now tail recursive
|
|
o the MOP for gf is now "public" (i.e. you can change the way
|
|
gf are called in Scheme -- it was not possible with previous
|
|
versions without using C).
|
|
|
|
- Port implementation is different: A port contains now its
|
|
input and output handler. New primitives to access the handler:
|
|
when-port-readable and when-port-writable.
|
|
BTW, The Tk function fileevent function is no more useful
|
|
(it is written in Scheme now for compatibility, but its usage
|
|
is deprecated). It may not be supported in a future release.
|
|
|
|
- New composite widgets: <Multiple-window> and <Inner-window>
|
|
which allow to have embedded windows. A multiple window
|
|
has a task bar below and allow to iconify inner-windows.
|
|
Some people think it looks like Win95 desktop ;-)
|
|
|
|
- pixmap extension doesn't require anymore the Xpm library. Code
|
|
is stolen from the Tix Library.
|
|
|
|
- New socket code which allow multiple concurrent connection
|
|
|
|
- Extended types can now have a compare function which is called
|
|
when eqv? or equal? is called. This modification should be
|
|
compatible with the previous extensions (I hope so)
|
|
|
|
- STklos: Two new methods: object-eqv? and object-equal? which are
|
|
called when applying eqv? or equal? to instances.
|
|
|
|
- A rewriting of bind-for-dragging canvas method. You can now specify
|
|
a :before-motion, which if it returns #f, forbid to move the selected
|
|
canvas item.
|
|
|
|
- New primitives:setenv!, posix-host-name, posix-domain-name,
|
|
posix-uname
|
|
|
|
- Option separator "--" allows to pass reserved keyword (sush as -help)
|
|
to a script. Option and parameter cannot be mixed anymore
|
|
(i.e. calling stk xyz -help ==> *argv* = ("xyz" "-help")
|
|
|
|
- HTML browser enhancement (support of the <FONT> tag with SIZE
|
|
and COLOR sub-tags. This must be compatible with the HTML spec.
|
|
|
|
- and of course many many bug corrections.
|
|
|
|
|
|
01/22/96 Release 3.0 (also called 3.0b2 by error)
|
|
~~~~~~~~~~~~~~~~~~~~
|
|
- Version of Tk is now at Tk4.0p2 level
|
|
|
|
- Support Pixmap images
|
|
|
|
- Strings can now contain null charters (printing of strings is more
|
|
friendly now in write mode
|
|
|
|
- Executable is now position independant(i.e. no path coded in hard in
|
|
the interpreter). STK_LIBRARY shell variable is no more necessary. We
|
|
can now make binary distributions.
|
|
|
|
- Signal can now be redirected to Scheme closures. The end of a GC
|
|
is seen as a signal.
|
|
|
|
- Trace on variable are changed (and re-work now): the associated trace
|
|
must be a thunk now.
|
|
|
|
- New option for buttons, checkbuttons, radiobuttons and entries:
|
|
:stringvalue.
|
|
This options tells if the value must be stringified or not.
|
|
For instance, with
|
|
(radiobutton '.c :text "Try" :variable 'x :stringvalue #f :value 100)
|
|
will set the "x" var to "100" whereas with
|
|
(radiobutton '.c :text "Try" :variable 'x :stringvalue #t :value 100)
|
|
value is set to the integer value 100
|
|
Default value for :stringvalue is #t for entries and #f for check and
|
|
radio buttons.
|
|
|
|
- stk-wtour demo is updated for STk 3.0
|
|
|
|
- In STklos, if a method M is defined and if it is already bound to
|
|
a procedure, the old procedure is called when no method is applicable.
|
|
Example:
|
|
(define-method car ((x <integer>)) (- x 1))
|
|
(car 10) ==> 9
|
|
(car (cons 'a 'b)) ==> a
|
|
As a consequence, this kind of method cannot call no-applicable-method
|
|
if parameters are not valid:
|
|
(car (vector 1 2)) ==> error car: wrong type of argument: #(1 2)
|
|
|
|
- Small change in the STklos hierarchy. <widget> is now a subclass of
|
|
<procedure> and its meta class is <procedure-metaclass>.
|
|
|
|
|
|
10/07/95 Release 3.0b1
|
|
~~~~~~~~~~~~~~~~~~~~~~
|
|
A lot of modifications. Briefly,
|
|
- Support of Tk4.0
|
|
- Closures are fully supported by Tk. That means that a callback can be
|
|
now a Scheme closure with its environment. GC problems with closures
|
|
and usage of the dirty "address-of" are definitively gone.
|
|
- HTML support (a browser is provided, should be extended to support
|
|
all HTML2.0)
|
|
- Documentation is now in HTML for the Tk commands (only a few commands
|
|
are ready for now, but they will be all defined in a near future).
|
|
- ....
|
|
|
|
|
|
07/15/95 Release 2.2
|
|
~~~~~~~~~~~~~~~~~~~~
|
|
|
|
This is the last release with Tk 3.6. Next release will integrate Tk 4.0
|
|
|
|
- Bug corrections
|
|
- Changing Makefiles and configure files for better dynamic loading
|
|
integration.
|
|
- Adding support for BLT-1.7. This library can be loaded dynamically
|
|
on system which support it
|
|
- New option which permit to change the initial amount of cells
|
|
- Uses really LESS memory.
|
|
- New GC. Now we have a set of heaps and a new heap is allocated as
|
|
soon as the global space is "nearly" filled.
|
|
- SLIB support (just type (require "slib") and after that process as
|
|
indicated in SLIB documentation
|
|

|
|
- Adding support for Text in STklos: Definition of the <Text> class
|
|
(and companion <Text-tag> class).
|
|
- call/cc is now tail recursive. (Alas, methods and dynamic-wind are
|
|
not yet tail recursive).
|
|
- Better support for autoloading files
|
|
- Adding support for an exec function a` la Tcl (i.e. execute of a
|
|
unix process and keep its output in a Scheme string)
|
|
- General run-process for running Unix process were std{in,out,err}
|
|
can be redirected in files or in pipes.
|
|
- Some code has been rewritten to ease STk porting
|
|
- Adding support for regular expression pattern matching and
|
|
replacement
|
|
- There is now a light interpreter, called snow (for Scheme
|
|
NO Window); this is in fact 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.
|
|
- New organisation of intalled file to permit co-existence of
|
|
several version of STk or multi-architecture file sharing
|
|
- Dynamic loading support for NetBSD-1.0
|
|
- Dynamic loading support for HP
|
|
- Dynamic loading and dump support for FreeBsd.
|
|
- Dynamic loading for Linux (using ELF format or the DLD package)
|
|
- A mini interface builder (very simplistic, but usable)
|
|
- New contributions: A true Tetris game, a 8 queens simulation and
|
|
a demo of composite widgets.
|
|
- Every exported identifier now starts with the string "STk_" to
|
|
avoid name clashes when embedding the interpreter in an application.
|
|
- BSD sockets support
|

==============================================================================
|
|
??/??/?? Release 2.1
|
|
~~~~~~~~~~~~~~~~~~~~
|
|
|
|
This is a major release version.
|
|
|
|
- STklos (the object layer) is now written in C. It is more than 150
|
|
times faster than before and it uses less memory (~ 1/100)!!!!
|
|
- Improvement of STklos
|
|
- STklos classes have been written for all the Tk library widgets
|
|
- Composites widgets can be easily defined in STklos. Access to those
|
|
widgets is identical to C written one.
|
|
- bindings can be now true lambda expression with their own
|
|
environment (rather than list which are evaluated in the global
|
|
environment).
|
|
- Hash tables have been added.
|
|
- Small constants are coded on a pointer rather than a cell
|
|
- Support for dynamic loading on SunOs (4 and 5). Dynamic loading
|
|
uses shared objects (it should work also on OSF1)
|
|
- Dump creates now smaller images.
|
|
- Modification of configure and Makefiles to correct of a lot
|
|
of installation problems.
|
|
- Runs on Solaris 2.3
|
|
- Bugs corrections
|
|
- Some modification to the error notifier
|
|
- Support of dynamic loading of shared objects on Solaris 1 & 2 (it
|
|
should work also on OSF1).
|
|

|
|
|
|
94/01/03 Release 2.0
|
|
~~~~~~~~~~~~~~~~~~~~
|
|
|
|
STk 2.0 contains a completly rewritten Scheme interpreter. This new
|
|
interpreter is
|
|
- R4RS
|
|
- faster than previous release (~ 3 or 4 times)
|
|
- less bugged (I hope :-) )
|
|
- implements integers (32 bits and bignum) and floats
|
|
- cleaner with macros
|
|
|
|
This version contains also a prototype of a graphical inspector which
|
|
permits to see/modify a variable value. For widgets variables it permits
|
|
to modify interactively their behaviour. However, it doesn't yet contain
|
|
a C rewritting of the object layer as it was planned. This will be done
|
|
in a (probably the) next release.
|
|
|
|
93/09/02 Release 1.00 (first public release)
