I don't know where you got the notion of "nested" in the above comment, but I think you are actually wrong and that it is irrelevant here. When you define an autocommand (call as parent), adding nested keyword allows other autocommands (call as children) to be triggered from the actions performed by the parent autocommand. If BufReadPost got triggered, it means it either triggered as a parent autocommand (as a direct user action), or as a child autocommand of another parent autocommand that allowed nesting. Given the above explanation, I still don't understand the comment. Is there a different autocommand that gets triggered while dnding files? If so which one is it? If that autocommand allows nesting, how are we detecting that BufReadPost is being nested (or a child, in my terms) here (I don't see any special condition). Last but not least, why is setting a position in such a situation wrong? In any case, I actually tried doing dnd of files on gvim with this autocommand, and it seems to just work fine, preserving cursor positions. Is the comment not relevant anymore? Would you care to elaborate your earlier explanation? Sorry for being so finicky, I just want to understand that's all. -- Thanks, Hari __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
