In an ideal world, I would spend more time on this and add --edit-sparse, which opens up $EDITOR, lets you edit the patterns and reapplies the patterns after $EDITOR exits (catching faults if possible). Unfortunately I don't use sparse checkout as much as before and therefore have little motivation to do it. I would really like narrow clone to replace sparse checkout, but I haven't made much progress on that front either. I'll try to get back on that once pathspec-magics topic is settled. > This patch isn't about tweaking the sparse-checkout pattern; instead, > it's about how "git checkout" interacts with the skip-worktree bit. > Maybe a good name would be --respect-skip-worktree? I'm bad at naming.

There may be scripts that expect "git checkout -- foo" to reset everything in "foo". Or maybe you just want to check out a single file and do not bother to edit sparse patterns as you won't need it for long. -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
