Scx is a graphical user interface library for scsh and Scheme 48. Scx already provides a direct binding to Xlib. The next step will be a binding to Xt, after this we will turn to a popular widget set.

Scx is currently maintained by David Frese and Norbert Freudemann. Scx 0.2 is available as scx-0.2.tar.gz @ ftp.scsh.net.

Public CVS access is available at SourceForge, where you can browse the scx repository.

FreeBSD maintains a port of scx.

For the current version of Scheme 48, there's s48-scx (mercurial repo).

Orion is a window manager for the X11 windowing system. Orion is written in Scheme and accesses Xlib via the scx library for scsh. Orion is in fact a family of window managers that can be nested. This enables great flexibility and efficient handling of X11 applications. Orion currently comes with four child window managers:

• a conventional moving window manager
• a window manager for stacking windows in a frame
• a window manager for splitting windows horizontally and vertically
• a work space manager

Orion also supports saving the window manager layout and programmatic configuration.

The Orion distribution (orion-0.2.tar.gz) uses the scx library for scsh.

Some screenshots of Orion in action:

• Ion like (switch-wm and spilt-wm)
• switch-wm only
• move-wm only
• a move-wm above a switch-wm
• a move-wm within a (splitted) switch-wm
• a switch-wm within a move-wm

There is also a FreeBSD port of Orion.

Check out the orion-wm module in the scsh SF repository for further mation.

Scheme-XP implements the client-side X library from the socket layer up. Release 0.1 implements much of the underlying structure as well as 29 X protocol calls. There are a few example programs, and it should be relatively straightforward to add remaining calls and write your own cool little toys. Written by Mike Wilson.

a drawing package à la Carbon contributed by Johan Ceuppens to sunterlib. It is based on Xlib for scsh and thus needs scx-0.2.

Extract vital stats from images in the formats used on the web: gif, jpeg, png, e.g. when generating web pages with inline images. (You don't want to determine the width and height attribute values of img elements by hand.) Ports loosely a small part of Marco Schmidt's ImageInfo 1.3, a public domain Java program. Hosted by the Scheme Untergrund Library.

Read entries from the (first) image directory of TIFF files: width, height, etc. Ports Oleg Kiselyov's tiff reader. Hosted by the Scheme Untergrund Library.
