Call Graph Generator

Call Graph Generator

Hi,

I've hacked some tcl code to generate graphviz files
for the call graph of a project. I don't know if such
a thing was available elsewhere but it works for me (TM)
Makes classes into clusters and places their methods in
them. Each arc represents function use.

The small hack is based on call-freq code...
Even the name is call-graph.tk although it doesn't
do GUI yet...

It's not even alpha, so I await your comments.

I've already used it to generate the call graph of a large C++
project and I expect that it will be very useful for others, too.
If you have requests for different kinds of graphs, feel free
to ask for them as they'll be probably useful for all of us!

Thanks!

I'm really interested to see some screen shots -- can you post a URL or two?

Yeah, why not? Here's the huge (I mean large...) ps file. gzipped.

and the dot input files,  (vanilla and edited)

I could show it on tk window if tcldot worked with the old tcl/tk version
that sourcenav uses. :( When you guys finish porting that to tcl8.3
we can make this into another navigator window!!!

Happy hacking,

Very nice!  I think this would be a nice contribution to S-N, even if it's
just a tool that emits the dot files.  As for how it could be included in
the product, I'll leave that up to the S-N team to contemplate.

Hi,

some other quick hacking (it was my first time in tcl ;-) ) on the Call
Graph Generator which makes it still more interesting to me, so maybe
also to others :
* the edges are drawn in different colors
* calls within the same class are drawn dashed
* constructors are trapeziums
* as third command line argument a file can be optionally given, which
must contain one line with all files (with full path as in the sn project)
separated with a space out of which the functions have to be drawn. This
was handy because otherwise if you have e.g. a server and client with each
a main function, it was drawn as one main function.

Still a problem : if a function of one class calls a function with the
same name on a pointer which refers to another class, then it is drawn as
a loopback, but this seems a problem with the parser of SN, I think.

It would be nice if the instance variables were also drawn for each class
(.iv database) and if optionally also references to these could be drawn.

best regards,
and some cool tools ;-)

quite good.. in fact, better than the actual ones
