I have no idea what is the size of your repo. About a year ago I had to convert a repo with about 30k patches. I had to do it fast, so I did not do proper solutions, but hacks. It's available here: http://vmiklos.hu/project/tailor/ During the last year I submitted back most of the changes to tailor, but the performance issue is still there. I broke the possibility of an incremental conversion, but this way I was able to convert such a big repo, too. NOTE: IIRC there were a few differences when I replaced _darcs with .git, but they were really minor, so I would not worry about it. > The GitHub URL for my converter: > http://github.com/freshtonic/darcs-fast-export/tree/master > > The clone URL: > git://github.com/freshtonic/darcs-fast-export.git > > Thanks in advance for any advice/code/time. If you use fast-import... http://repo.or.cz/w/darcs2git.git did you try this one? It properly parses the darcs patch format and maps darcs conflict resolutions to git merges. My problem with it was it did not handle special authors names, like empty author and other small problems. I also did a lot of work on tailor when I found darcs2git. But I think if you want to work on something, darcs2git would worth at least a look. Ah and sorry for not commenting your code, but I don't know Ruby at all. ;-)
