<B>STk</B> 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package where the Tcl language has been replaced by Scheme.
|
|
|
|
<P>
|
|
<B>STk</B> also provides an efficient object oriented system called <B>STklos</B>.
|
|
<B>STklos</B> is an extensive OO system with multiple inheritance, generic
|
|
functions, multi-methods and a Meta Object Protocol).
|
|
|
|
<P>
|
|
This release runs on majors Unix versions (Linux, Solaris, OSF, ...)
|
|
Starting with Release 3.99.4, <B>STk</B> also runs on Microsoft Win32 systems.
|
|
|
|
|
|
<P>
|
|
Version 3.99 uses the Tk 8.0 package for the graphical part (actually Tk 8.0.3).

|
<H2>Features of STk</H2>
|
|
|
|
<ul>
|
|
|
|
<li> Interpreter is conform to R4RS, with some additions of R5RS (e.g.
|
|
multiple values and dynamic-wind)
|
|
|
|
<li> <B>STklos</B> is an extensive OO system with multiple inheritance,
|
|
generic functions, multi methods, a Meta
|
|
Object Protocol.
|
|
|
|
<li> Interpreter can be easily extended by adding new C modules.
|
|
|
|
<li> All the commands defined by the Tk toolkit are available to the <B>STk</B>
|
|
interpreter (Tk commands are seen as a special type of objects by the
|
|
interpreter).
|
|
|
|
<li> Callbacks in a GUI are Scheme closures
|
|
|
|
<li> Supports Tk 8.0
|
|
|
|
<li> Doesn't use the Tcl interpreter when using Tk widgets
|
|
|
|
<li> Tk variables (such as "-textvariable") are reflected back into Scheme
|
|
as Scheme variables.
|
|
|
|
<li> A set of <B>STklos</B> classes have been defined to manipulate Tk commands
|
|
(menu, buttons, scales, canvas, canvas items) as <B>STklos</B> objects.
|
|
|
|
<li> New widgets can easily be built in Scheme by composition of existing
|
|
widgets. Some of the more common composite widgets (file-box, color chooser,
|
|
gauges, ...) are provided with the package.
|
|
|
|
</ul>
|
|
|
|
|
|
<H2>Main Changes since Release 3.1.1</H2>
|
|
|
|
<ul>
|
|
<li> A module system has been added
|
|
|
|
<li> Integration of the Bigloo MATCH-CASE and MATCH-LAMBDA
|
|
primitives. Furthermore, the file bigloo.stk provide
|
|
some compatibility between <B>STk</B> and bigloo modules.
|
|
|
|
<li> 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).
|
|
|
|
<li> Integration of the Tk8.0 toolkit
|
|
|
|
<li> The MOP of <B>STklos</B> is now very similar to the CLOS one.
|
|
|
|
|
|
<li> When a class is redefined, the instances and methods which uses it
|
|
are redefined accordingly, as in CLOS.
|
|
|
|
<li> Generic functions can be now traced with the standard TRACE
|
|
function.
|
|
|
|
<li> Some new composite widgets: Gauge, Valued-Gauge, Balloon-help, ...
|
|
|
|
<li> 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.
|
|
|
|
<li> Works on Windows too (need some more testing, since this is
|
|
far form perfect)
|
|
|
|
<li> A console mode (which is used by default on Windows, but can
|
|
be used with the -console option on Unix)
|
|
|
|
<li> A new editor with Scheme fontification and indentation is provided
|
|
|
|
<li> New kind of ports: virtual ports
|
|
|
|
<li> Numerous bug corrections
|
|
|
|
<li> ...
|
|
</ul>
