A Connected Graph

A UML Diagram

An Auto Generated UML Diagram with source browser

COGRE is pronounced similarly to cougar. It is a base library for editing and manipulating connected graphs. Additional tools will be available using COGRE for managing diagrams for UML flavors, such as a class hierarchy diagrams.

The short term goal of COGRE is just to be able to create and manipulate a few boxes linked together with lines in an Emacs buffer (or in an external graphical editor, if an appropriate solution can be found.)

The long term goal of COGRE is to provide round-trip design to code development. Semantic will parse a code in a project, and COGRE will either generate, or associate those tags with a UML diagram. Editing the diagram will then allow COGRE to save those changes back into code using SRecode.

This pie in the sky will not be possible without help. Consider creating and maintaining a language definition for Semantic, or helping define the proper blocks and link routing code for COGRE, the base graph editor. If coding is not your thing, consider making a spiffy graphic cougar for a logo, testing, or helping to document COGRE.

Downloading CEDET

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

Latest Stable Release: CEDET 1.1

Try out cedet-1.1.tar.gz.

CEDET 1.1 includes all the security fixes from 1.0.1, a long list of bug fixes, and additional new features to support Java, Android and Arduino programming!

Our goal for CEDET 1.1 is that this will be the LAST release using the current install and file organization schemes. This will also be the last release to support Emacs 22! Future released versions will use a new file system scheme compatible with Emacs 24.<

After building CEDET 1.1, consider joining the mailing list and help make CEDET better.

Previous Stable Release: CEDET 1.0.1

The previous stable release is cedet-1.0.1.tar.gz. You will need CEDET 1.0.1 for older versions of Emacs, such as Emacs 21 or 22.1.

About this Security Release:
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.

CEDET Development

Did you find a bug?

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

When using CEDET from Git, please note that we are transitioning to a new file and install scheme to be more compatible with Emacs 24. Changes will be required in your .emacs.

Emacs Version Support:

CEDET 1.0.1, and 1.1* has TWO automated build processes, one via Make, and the other via starting Emacs, and executing a build command.

This table shows the automated testing done for the release of CEDET 1.1:

Emacs 21 CEDET's test suite will fail, but most parts still work for CEDET 1.0.1.

XEmacs Neither build process works with XEmacs 21.4. It is possible to build parts of it by hand it so it works however.

SXEmacs We have integrated patches to support SXEmacs, but we haven't tested it ourselves. Parts of CEDET have been reported to install and work.

Windows XP/7 If you do not have cygwin, you will need to use the cedet-build.el script to build CEDET.
