29.0.60; [PATCH] save-place-mode cannot restore saved position |
Date: |
Fri, 24 Mar 2023 10:19:07 +0800 |
Hi,
save-place-mode cannot restore last saved position when
`save-place-abbreviate-file-names' is non-nil:
- emacs -Q
- M-x save-place-mode, and set save-place-abbreviate-file-names to t
- open a file, scroll to some position, and kill buffer
- reopen the file, the position is not restored
The reason is it uses abbreviated file names when saving positions to
`save-place-alist', but uses full file names to find position in
`save-place-alist'.
Best,
Liu Hui

Thanks, I installed this on the master branch, and I'm therefore
closing this bug.
