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, 23, XEmacs 19.1x, 20.x and 21.x. Byte compiling EIEIO is VERY IMPORTANT for performance.

Tools using EIEIO

Semantic

Parser Generator. The Database which tracks tags between sessions uses EIEIO persistent data classes.

EDE

Emacs Development Environment uses EIEIO to track project information, and uses persistend data classes, instance inheritors, and instance trackers. It also uses speedbar classes to provide a project overview.

SRecode

Semantic Recoder template manager uses EIEIO to handle template tables.

COGRE

COnnected GRaph Editor uses EIEIO to track graph elements.

JDE

Java Development Environment for Emacs uses EIEIO to manage the debugger, dialogs, and more.

ECB

Emacs Code Browser. Browse your files and source code.

XAE

XML Authoring tool.

jomtool

Java code generator.

Notes:

EIEIO should work with Emacs 19.3x, 20.x, and 21.x. It should also work (and is usually included with) XEmacs 20.x, and 21.x.

Downloading CEDET

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

CEDET 1.0.1 is available! Send in bug reports on the build process, or anything else to the mailing list.

Try out cedet-1.0.1tar.gz.

Please Note:
CEDET 1.0 has a security issue related to loading project files with EDE. If you are using CEDET 1.0, please upgrade to CEDET 1.0.1 to recover from this issue. If you use Emacs 23.3 with built-in CEDET, please upgrade to Emacs 23.4 or later, apply the patch, or upgraded to CEDET 1.0.1.

After building CEDET, consider posting to the mailing list to let us know how it went!

Please Note:

If you encounter build problems with a CEDET release, those issues may have already been fixed in Bazaar! 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 Bazaar version directly.

Emacs Version Support:

CEDET 1.0.1 has two automated build processes, one via Make, and the other via starting Emacs, and executing a build command. These have been tested on Linux with Emacs 22 and 23.1. CEDET will also build and work for Emacs 23.2, though the version of CEDET that comes with Emacs 23.2 has been reported to conflict for some.

Neither build process works with XEmacs 21.4. It is possible to build parts of it by hand it so it works however. If anyone knows how to fix the build, please let us know.

In Emacs 21, CEDET's test suite will fail, but most parts still work.

On windows, you will likely need to use the cedet-build.el script to build CEDET.
