[Lemon-user] Question for layout capabilities.

[Alpár Jüttner]

Hi,

> Does lemon library exports in .dot format?

Not yet, but it is easy to do by hand. For example if you need no extra
customization, this will do the job:

std::cout << "digraph G {" << std::endl;
for(ListGraph::ArcIt a(g);a!=INVALID;++a)
  std::cout << "n" << g.id(g.source(a))
            << " -> " << "n" << g.id(g.source(a))
            << std::endl;
std::cout << "}" << std::endl;


The dot language is described here:
http://www.graphviz.org/content/dot-language
This one is a nice (though a bit outdated) tutorial to the .dot
language: http://www.graphviz.org/pdf/dotguide.pdf

Of course, if anyone takes the hassle of developing a configurable
general purpose .dot exporter, we are very happy to add it to lemon.


Regards,
Alpar
