RE: [gentoo-dev] An Offering: the EMerge Interface

["Will Rogers" <wjr@wam.umd.edu>]

Karl,

I rewrote the entire thing in Python (partly to see if I could).  I
haven't tested it as much as the original because it's 2am and I have to
be at work in seven hours, but I was able to merge and unmerge joe, as
well as query a bunch of stuff, without any trouble on my system.  It is
at present a lot slower than the Perl version because I used
os.path.walk instead of opening a pipe from find, but I'll probably
change that given the horrid performance it causes.

I send this directly to you because I get the faint impression that
gentoo-dev is not the correct place to send this sort of thing and I
didn't want to nag anyone without some guidance ;)

The new version is posted at http://www.wam.umd.edu/~wjr, but as you can
see I consider it a beta (more because of performance than stability--it
takes several seconds to execute a dependency check with around 8
dependencies).

Will Rogers, going to sleep.
