Dear Cedet Developers, I am pretty interested in cogre and I am eager to see how it would perform. But I personally cannot find any useful resources or tutorials related with this tool and the html documentation is UNREACHABLE: http://cedet.sourceforge.net/info/cogre.html Could you please give me some hint that how can I find useful resources. Thanks. |

Hi, There is a doc file cogre/cogre.info created when you build CEDET. I need to fixup the website with the published doc but haven't gotten around to it.

Hi, Sorry about the slow response. It's been catapult season for me. On 10/09/2011 12:41 PM, Philipp Haselwarter wrote: > "Eric M.

Not as complete as it could be. > Cogre sounds like such a good idea, but it is indeed not obvious how to > actually use it, some real world tutorial could be quite helpful! Part of the reason is that some of the workflows are incomplete in COGRE. It is ok to create diagrams, move nodes, and do lots of stuff, but much of the framework is set up to accomplish a core round-trip solution, and there is no good way to add key details to your UML for code gen. It is actually easier to generate the simple code, edit the code, and ask cogre to refresh it's diagram from your code than create a UI to let you type in attributes for your class. Also, I can't really work on enhancing cogre anymore for some random non-technical reasons. If a volunteer who can sign over changes to the FSF would like to take over aspects of COGRE, I would be happy to assist any way I can. > Eg when I use `cogre-uml-quick-class' and save the output buffer to a > file, after reopening the file I can't see the graph anymore, just > text. And the *.dot files…how do you actually use those? If you save a cogre diagram, it should load back in. Of course, you need to add a .cgr extension to the save file. While poking around, I just noticed that is never enforced. No wonder it was confusing. dot files are for the dot program, which is a utility that draws connected graphs. COGRE uses .dot files as a way to export your graph to DOT so that you can use dot to create nicer looking print diagrams, or so cogre can directly export to png and other output types. Cogre also uses the dot layout engine if you select the Layout menu option. > Can cogre generate a class diagram for a whole project?

I did make that work once, but it depended on a tool that was deprecated from CEDET as it was unmaintainable. Unfortunately, I had no layout engine, so needless to say, it was rather unpleasant. There is no code I know of to do what you want, but a quick call to semanticdb-find-tags-by-class for 'type could get you a list of everything making repeated calls to the quick-class function on anything that doesn't inherit from anything and then call the dot layout engine. Might not be too bad to do. Eric |
