- This is the release 3.1 of STk
- --------------------------------
-
-
- (Last release is always available from kaolin.unice.fr [193.48.229.225])
-
- 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- package where the Tcl language has been replaced by Scheme.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 several Unix boxes (see below) and on Microsoft
- Win32. It uses the Tk 4.1 package for the graphical part.
-
- DIFFERENCE PREVIOUS RELEASE
- ---------------------------
-
- - 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
- (such as -help) to a script. Option and parameter cannot
- be mixed anymore:
- 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.
-
- See file 'CHANGES' in the distribution main directory for more informations.
-
- SCHEME WITHOUT TK
- -----------------
-
- 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.

- |___ 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
- | (hash tables, POSIX.1 support). See the README file for more
- | details
