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.
