Problems with relative indicator (scroll bar)

[mrcnski]

I'm using the indicator from the readme to show the current position in a buffer.

It generally works pretty well but messes up when the point is at the end of a buffer. The indicator no longer shows the position in the buffer accurately and sometimes (I can't reproduce this consistently) I am not able to scroll the buffer away from the point.

Let me know if I can provide any more info (can take a screencast if you'd find it helpful). Thanks!

The problem is that emacs can only show things on the side of existing lines in the buffer. When you get to the end of the buffer the "empty space" after the last line is not addressable so the indicator jumps around to some possible position (where it ends up is quite random at the moment).

There's no easy fix currently as this is pretty much baked in into Emacs's display engine.

Thanks for the quick response! Hmm, is it possible for indicators to be disabled in this situation?

And is it possible to at least fix the scrolling issue? When I'm at the end of a buffer I (sometimes) can't scroll away unless I move the point up first, which is a bit annoying. I just doublechecked and confirmed that this is caused by indicators-mode.

What Emacs version are you using? I've been using this for quite some time with flycheck and it never happened to me that I couldn't scroll. Also, what exactly do you mean by scrolling?

Can you paste your config?

Hey, sorry for the delayed answer. Emacs version:

GNU Emacs 26.1 (build 1, x86_64-apple-darwin14.5.0, NS appkit-1348.17 Version 10.10.5 (Build 14F2511)) of 2018-05-31

Also, what exactly do you mean by scrolling?

I like to scroll using (scroll-down-line 6) (bound to a hotkey, of course). Sometimes when the point is at the end of a buffer, scrolling gets "stuck" and I can't scroll away.

Can you paste your config
