EIEIO is an Emacs lisp program which implements a controlled object-oriented programming methodology following the CLOS standard. EIEIO also has object browsing functions, and custom widget types. It has a fairly complete manual describing how to use it.

EIEIO also supports the byte compiler for Emacs and XEmacs. Because of the nature of byte compiling, EIEIO is picky about the version of Emacs you are running. It supports Emacs 19.2x+, 20, 21, 22, and CVS, XEmacs 19.1x, 20.x and 21.x. Byte compiling EIEIO is VERY IMPORTANT for performance.

Downloading CEDET

All the CEDET tools are available from a single distribution file.

CEDET is currently driving toward a 1.0 release. Try out a pre-release and send in bug reports on the build process, or anything else to the mailing list.

Try out cedet-1.0pre6.tar.gz.

After building CEDET, consider adding your results to the prerelease tested configuration page by adding your own platform information.

Please Note:

If you encounter build problems with a CEDET release, those issues may have already been fixed in CVS! CEDET has an active community of users that help identify and fix these issues quickly. You can check the mailing list archives or just try the CVS version directly.
