Of course, it is not just SCM's that are "blinded" by file orientation - every other tool (editors, compilters, etc) that we use has this orientation. An SCM really has to have some notion of file orientation, at least at the UI level, because every other tool we use has the same orientation. The ENVY/VisualAge environments tried to work with a pure class-level orientation and in some ways that was great, but most developers hated it precisely because it removed the file orientation and hence their ability to work with their favourite tools. IBM/OTI saw the light which is why Eclipse is avowedly a file-oriented platform. It seems to me that file-orientation is here to stay and it would be really cool to layer some kind of virtual filesystem over the git repository so that different trees become transparently accessible via different branches of a file system, e.g.: /mnt/gitfs/working # some kind of writeable virtual directory over the git cache /mnt/gitfs/c157067185209b50b350571fe762c2740ea13fc1 # read-only tree of commit c157... /mnt/gitfs/5b53d3a08d64198d26d4f2323f235790c04aeaab # read-only tree of comit 5b53... Given the purity of Linus' concept and his natural orientation towards file systems rather than SCMs, this seems like a rather natural thing to do. If anyone is planning to do this and wants a helper, count me in! jon. -- homepage: http://www.zeta.org.au/~jon/ blog: http://orwelliantremors.blogspot.com/ - To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
