问题


I need to get into and make some modifications to a software component written in C++. I am fantasizing about generating some map of the code, that would show relationships between classes and walk me through the flow / call graph of methods. Is there a tool for this?

Years ago I worked with Rational Rose modeling tool with had a feature of reverse-engineering the code and building a class diagram for it. However what's important for such project exploration is also some dynamic information like sequence diagram (ideally) or call graph. Not mentioning that Rose is too big for such one off task and actually I don't know if it exists at all still.


回答1:


I personally use Doxygen https://github.com/doxygen/doxygen and its truly among the easiest program to configure in a way that makes output like what you describe.

To generate call graphs you would also need dot which you can get in graphviz http://www.graphviz.org/. There might be some other dependency's but in those cases it should say so in the configuration file which by the way is rather well commented.

The configuration file of Doxygen might seem extensive at first, but the end result is worth it.

Warning, Douml was made from an old free version of BoUML (unfortunately not the last of them), when porting it in Qt4 the team introduced a lot of bugs, and at least because of that the result is unusable. Furthermore the team didn't worked on the plug-outs mechanism, so you aren't able to define you own plug-out etc. So it is better to get BoUML, it is not free but the price is very low compared to other UML tools. Zeks, BoUML has an automatic layout in the class diagrams. My two cents.

Take a look at BOUML, I think that's exactly what you're looking for:

If doxygen is not enough, I'd look into Enterprise Architect for the task. It's not free but it will generate your diagrams and code model. Although, tbh, I think doxygen is exactly what you need, and it's free to boot.

Btw, If you do decide to go Bouml way (generate code model, then make diagrams by hand), consider picking Douml from sourcefoge. Unlike Bouml, it's still free.
