 |
|
I have always wanted a more visual representation of the portage dependency graph, so I put together a little script:
| Code: |
#!/bin/bash
cd /var/db/pkg
pkglist=$(find . -maxdepth 2 -type d | cut -c3- | grep /)
{
echo "// gentoo package dependency graph"
echo "// machine: $(hostname)"
echo "// started at: $(date)"
echo 'digraph depgraph {'
echo ' ranksep=1'
echo ' nodesep=1'
echo ' overlap=false'
for pkg in ${pkglist} ; do
equery depends =${pkg} | cut -d'(' -f1 | sed -e 's%\(.*\)% "\0" -> "'${pkg}'"%g'
done
echo '}'
}
#| tee depgraph.dot | twopi -Tps
|
Just pipe the output of this script into depgraph.dot and feed that into twopi (media-gfx/graphviz).
The only problem left now is finding an image viewer that can actually handle such a huge graph.. 
Yours, Florian
P.S. I know very well that this is entirely unelegant and slow. So please improve it!

Did you find an image viewer for the dot file?
