* Possibly Weird Behavior Regarding First Lines Which are Invisible?

And I have a function which runs (previous-line) (beginning-of-line 1) and said function is bound to a key (let's say <up>). So I apply a text-property of 'invisible using (pos-bol) of the first line and (1+ (pos-eol)) in order to get the first line to disappear, like it's not even there. If I'm on line 3 and M-: my function, it does what I'd expect and (point) will return the (pos-bol) of the second line. But, if I execute my function by pressing <up> from line 3, (point) keeps returning back 1, the point of the beginning of line 1 rather than the point at the beginning of line 2. Is this expected behavior? I'd be less weirded out if running code through M-: gave back similar results but I get what I'd expect to happen no matter what code I run and only the unexpected behavior when running the exact same code via a key binding. I'm running version 29.1 (GTK+ version 3.24.37 but through the terminal; I wouldn't expect these to affect anything as much as the Emacs version, though. On Guix). ^ permalink raw reply [flat|nested] 2+ messages in thread

Yes, it is. After you press <UP>, the automatic point-adjustment moves point to before the invisible text. If you want to disable that, set global-disable-point-adjustment to a non-nil value. ^ permalink raw reply [flat|nested] 2+ messages in thread
