Class Diagrams

[Nicholas Van Weerdenburg]

Hi,

Is there a popular cross-platform way to generate UML diagrams from ruby code?

Thanks,
Nick

Not quite what you're looking for, but you can take a look at
ObjectGraph (objectgraph.rubyforge.org) at how to dymanically evaluate
classes and generate a png graph using GraphViz. You can set some
graphviz options to make the output *look* a bit more UMLish, but it's
not proper UML.

I am not aware of any tool that reads ruby to generate UML (and would
love to hear if there are!). You might have to follow the same process
as ObjectGraph, but generating an XMI document to load into an existing
tool.

There is just one more question that need to be asked: are you sure
that is what you need? I find that because of ruby compactness of code
and duck-typing arguments you rarely use much of inheritance etc. As
for activity diagrams, you can not normally get them from static code
analysis so you'd have to do them by hand anyway.

Cheers,
Assaph

ParseTree will get you started on such a tool.

I might be happy with objectgraph. I like UML, but hate UML tools. So,
I figure I could write Ruby and use a tool to visualize the code for
insight and creating documentation.

I'd also find it interesting to apply it to existing Ruby libraries to
get a sense of their structure.

Whether it is really useful, I won't know until I try .

Thanks,
Nick

I've meaning to look at it, but haven't had the time to-date.

Glom your orbs on this:

http://blog.zenspider.com/archives/2005/01/parse_tree_visu_1.html

(be sure to look at the "ginormous" link as well)

Not quite what you are asking for, but a good start and very very easy
to move in the direction you'd like. The code is only 66 lines for the
graph class, 61 lines for the sexp processor, and 86 lines to process
command line options and snoop classes. Not bad, eh?

Very nice. And nice sql table diagrams as well for your book web app.

metoo!

just a thing: there is rdoc --diagram that may help. Very little, but
better than nothing

I didn't even know there was such a thing. I'll check it out.

Thanks,
