08/02/12 22:21, Deniz DoganHi, I've been trying to "fix" the behavior of ERC's scroll-to-bottom module by hooking into erc-insert-post-hook. I thought that the state when that hook is executed would be that point is back in the input area, but it does not seem like it.Hi, What's your plan for scroll-to-bottom in ERC? Why do you need this hook in addition to the existing one? scroll-to-bottom in its current state is clearly suboptimal, and it has a pretty excessive CPU consumption when repeating characters.
I don't really have a fully thought-out plan yet, but I believe the new hook is necessary, because the other hooks are run when the point has moved away from its original position. At least I couldn't figure out how to write code that worked with those hooks.
Having looked at the code for scroll-to-bottom just now, I see that it uses post-command-hook, which is obviously not an acceptable solution for the reason that you mention.
A good compromise, in my opinion, would be to basically _not_ "scroll to bottom" on every single character insertion. With the addition of the post-display hook, when the user hits RET, the message will be sent, ERC will display that message, the new hook will run, and it will be recentered to the bottom again. This method is something I've personally used in rcirc for quite some time and I'm very happy with it.
(I've also been looking for an emacs-wide replacement, without much success. This would be something that says : emacs is not allowed to display anything past the end of a buffer, period - except when the buffer is not long enough. Just like every other software does. This is one of the things that bother me the most about emacs.)
I agree with you very much on this point!
