[gentoo-dev] dependency graph

[Nils Decker]

I have written a small tool that creates a dependency graph to be
rendered using graphviz.

I will submit it to bugzilla when i have written some docs and made
it a little bit smoother.

I am hoping for your suggestions.

Things i want to do:
  - draw installed packages boldface
  - draw enables USE-flags boldface
  - fix multiple constraints to one package.
    I don't know yet how to do this. It treats 
      ( >=foo-1.2.3 <=foo-2.0.0 ) like two seperate dependencies.

Preview at

Examples:

dependencies for dev-lang/ghc
http://www.ndecker.de/gentoo/depgraph/ghc-5.02.3.dot ( 14k )
http://www.ndecker.de/gentoo/depgraph/ghc-5.02.3.gif ( 912k, 4878x2345 )

dependencies for dev-php/mod_php
http://www.ndecker.de/gentoo/depgraph/mod_php-4.2.2.dot ( 22k )
http://www.ndecker.de/gentoo/depgraph/mod_php-4.2.2.gif ( 1.6m, 7200x2590 )

rendering a graph for all packages in portage has already taken 2 CPU-hours.
Maybe it will finish this week ;-)

  Nils
