Sincerely, I don't see any major utility to this tool, but the result |
| 11 |
is really nice and fun... Just as the photo on your webpage, |
| 12 |
which I really like ;) |
| 13 |
If you really want some ideas of improvements, then what about |
| 14 |
3-coloring your graph? |
| 15 |
More seriously, you can try to highlight dependency cycles, but their |
| 16 |
is probably no such thing between official ebuilds (but it may be |
| 17 |
useful when developing a new ones). |
| 18 |
And what about a "max-depth" option? |
| 19 |
You could also emphaze a little bit more the ordering of the graph: |
| 20 |
I think that your graphs are ordered bottom-up, but it's sometimes |
| 21 |
quite hard to see (there are some nearly horizontal edges). You could |
| 22 |
try to group nodes by horizontal layers, with the possibility for the |
| 23 |
user to choose between the "as soon as possible" and "as late as |
| 24 |
possible" orders. |
| 25 |
And a last idea (the hardest one) would be an SVG output (you know, |
| 26 |
the xml stuff for vector graphics); think of it on the gentoo.org |
| 27 |
packages list: Ask the depency graph of a package, look at it carefully, |
| 28 |
then wonder what is this "libfoo" your package depends on, and click on |
| 29 |
the corresponding node to see the answer, etc. |
| 30 |
|
| 31 |
That's all, keep up the good work. |
