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 from ftp://ftp.scsh.net/pub/scsh/packages/scx/scx-0.2.tar.gz.

Public CVS access is available at SourceForge. Here you can browse the repository.

FreeBSD maintains a port of scx.

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 <ftp://ftp.scsh.net/pub/scsh/packages/orion-wm/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 Wiki for further information.

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.

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.
