Agreed. Grok's big. It has a lot of features (good), and a lot of code (a liability). It makes choices about the defaults more than BFG does. Due to its Zope 3 heritage it doesn't tend to lock you into defaults very much, but they're there and that might be trouble enough for some. Grok and Zope 3 are extremely similar systems and are (mostly) mutually compatible. Grok is definitely a far easier way to get started with Zope 3 than Zope 3 itself is, as Zope 3 has traditionally had sucky documentation (with some exceptions, in particular Philipp von Weitershausen book on it). Grok has reasonable documentation in reasonable quantity, though could always be better. BFG is small. It has less features (so more to write yourself), and less code (so easier to understand and hack on). It makes fewer choices and also simply does less. BFG has excellent documentation from what I've seen. BFG is a lot faster, though Grok's not exactly a slow-poke either, and probably more than fast enough for most projects. Grok has more legacy cruft due to it being built on a huge amount of the Zope Toolkit stack, though Zope Toolkit legacy cruft is probably like other people's non-cruft. But it's still cruft and we still need to get rid of it. As a lead developer on Grok, I obviously would recommend Grok for its features (and a wide selection of extensions in the Zope Toolkit and Grok world which you can use), and its ability to deliver those features "out of the box". That said, I also see the great attraction in something lighter and simpler, and I'm jealous of BFG for that reason. So we're trying to fix Grok (and the underlying code) so it's going to be more simple underneath. But it will be a very long time coming, and BFG will very likely be simpler forever. And do less forever. :) Regards, Martijn _______________________________________________ Repoze-dev mailing list Repoze-dev@lists.repoze.org http://lists.repoze.org/listinfo/repoze-dev
