Confirmed.
This is caused by ol-docview's assumption (see org-docview-open) that
org-open-file does not open non-existing file, as it is stated in
org-open-file docstring:
>> If the file does not exist, throw an error.
However, the docstring is not quite correct. Below is code in
org-open-file that is repronsible for throwing the error:
(when (and (not (eq cmd 'emacs)) ; Emacs has no problems with non-ex files
(not (file-exists-p file))
(not org-open-non-existing-files))
(user-error "No such file: %s" file))
Clearly, throwing or not throwing error is controlled by
org-open-non-existing-files and org-open-file never throws an error with
non-nil first optional argument (IN-EMACS).
This code has been introduced years ago by Carsten.
We have several options to fix the issue:
1. Only fix the reported issue in ol-docview.el and extend org-open-file
documention
2. In addition, make org-open-file throw an error when opening non-existing
files in
emacs (unless org-open-non-existing-files is non-nil)
The second option poses a risk of breaking existing configs.
WDYT?
Best,
Ihor
