This is the release 4.0 of STk
|
|
-------------------------------
|
|
|
|
|
|
(Latest release is always available from <ftp://kaolin.unice.fr/pub/STk> )
|
|
|
|
STk is a R4RS Scheme interpreter which can access the Tk graphical
|
|
package. Concretely it can be seen as the John Ousterhout's Tk
|
|
package where the Tcl language has been replaced by Scheme.
|
|
|
|
STk also provides an efficient object oriented system called STklos.
|
|
STklos is an extensive OO system with multiple inheritance, generic
|
|
functions, multi-methods and a Meta Object Protocol).
|
|
|
|
This release runs on majors Unix versions (Linux, Solaris, OSF, ...)
|
|
|
|
This version also runs on Win32. Consider this port as beta.
|
|
|
|
Version 4.0 uses the Tk 8.0.3 package for the graphical widgets.
|
|
|
|
|
|
DIFFERENCE PREVIOUS RELEASE
|
|
---------------------------
|
|
|
|
Only major changes are listed here. See the file 'CHANGES' in the
|
|
distribution main directory for more informations.
|
|
|
|
|
|
* A module system has been added
|
|
* Integration of the Bigloo MATCH-CASE and MATCH-LAMBDA
|
|
primitives. Furthermore, the file bigloo.stk provide
|
|
some compatibility between STk and bigloo modules.
|
|
* A simple FFI has been added. It allows to access C
|
|
functions without writing C code (works only on a
|
|
limited set of architectures for now).
|
|
* Integration of the Tk 8.0.3 toolkit
|
|
* The MOP of STklos is now very similar to the CLOS one.
|
|
* When a class is redefined, the instances and methods
|
|
which uses it are redefined accordingly, as in CLOS.
|
|
* Generic functions can be now traced with the standard
|
|
TRACE function.
|
|
* Some new composite widgets: Gauge, Valued-Gauge,
|
|
Balloon-help, Notespad, Hierarchies, ...
|
|
* The HTML-browser has been enhanced to access now the
|
|
web (i.e. you can grab distant texts or images). The
|
|
Web browser admit now applets written in Scheme.
|
|
* Numerous bug corrections
|
|
* Runs on Win32 platforms
|
|
* New option -console to run STk in a windowed environment
|
|
(with indentation and fontification).
|
|
* define-syntax
|
|
* SRFI-{0,2,6,8,9}
|
|
* New License Policy (request for commercial apps no more needed).
|
|
* ...

SCHEME WITHOUT TK (for Unix Only)
|
|
-----------------
|
|
|
|
Standard make build a light version of STk which does not provide support for
|
|
the Tk toolkit. This interpreter, called Snow (Scheme with NO Window), can be
|
|
called directly with the 'snow' shell script. It is implicitly called if
|
|
your DISPLAY variable is not set.
|
|
|
|
LEARNING STk
|
|
------------
|
|
|
|
In Contrib/STk-wtour, you'll find a program (called stk-wtour) which is a kind
|
|
of tutorial for programming widgets in STk. This program, which is a
|
|
contribution of Suresh Srinivas (ssriniva@cs.indiana.edu), is an excellent
|
|
starting point for learning basics of STk widgets programming.

|
|
Stk
|
|
|___ Contrib The contributors directory
|
|
|___ Demos some original Tk demos rewritten for stk plus some other
|
|
| stuff found on the net.
|
|
|___ Extensions This directory contains extensions of the core interpreter

|
|___ Doc Documentation of STk.
|
|
|___ Help Various (HTML) help files for STk.
|
|
|___ Lib a set of Scheme files used by the interpreter
|
|
|___ Stack files (very architecture dependant) for pushing args on

|
| the C stack. Used by the FFI of STk.
|
|
|___ Src contains source files of stk (i.e. the sources files of the
|
|
| interpreter + some glue files between Tk and Scheme).
|
|
|___ Snow contains (mostly) links over Src files. This directory
|
|
| is used to build snow the Scheme interpreter without Tk
|
|
| support
|
