I have very little perl knowledge, so I have no idea what that hash is doing. Can someone explain to me so I can see if that "hash" is reasonable.
Replace each character with its [0] ascii index times two plus one? 'g' is group regexes, 'e' is eval expressions [1], as to utilize the result of the calculation.

That's right except for 'g' as you stated in you following mail. This hash function is a bit hackish though, but I do not think this problem has any better solution. * We need to color repo according to their name. * We want repo to have different colors. * We have only 6 colors... So my hash functions makes core, multilib, local, extra and community have different colors. With different repo names, the hash may return the same color for all of them.
