AFAIK, remove-from-invisibility-spec simply does (setq buffer-invisibility-spec ...) let-binding is less cumbersome and not limited to outline spec which is not even used by Org.

I understand. current-column even express it clearly in the docstring (unlike, current-indentation). However, as I tried to explain, display-independent versions can be useful during parsing.

A simpler version would be let-binding buffer-invisibility-spec.
Note that there is similar issue with current-column, though
current-column is much less likely to be used without considering
display properties.
Would it be possible to include the "text" versions of
current-indentation and current-column into Emacs?
Something like
(defmacro org-current-text-indentation ()
"Like `current-indentation', but ignore display/invisible properties."
`(let ((buffer-invisibility-spec nil))
(current-indentation)))
(defmacro org-current-text-column ()
"Like `current-column', but ignore display/invisible properties."
`(string-width (buffer-substring-no-properties
(line-beginning-position) (point))))
If not, could you at least mention the invisible text issues in
`current-indentation' docstring? The current undefined behaviour is very
hard to debug.
Best,
Ihor

I guess you should temporarily remove the invisible property? Like
this:
(let ((invis-spec buffer-invisibility-spec)
indent)
(remove-from-invisibility-spec '(outline . t))
(setq indent
(save-excursion (search-forward " a") (current-indentation)))
(setq buffer-invisibility-spec invis-spec) indent)

This is needed for parsing. In Org, indentation defines the list level.
Similarly, indentation is meaningful in Python.
Since parsed text can be hidden inside fold (using org-mode,
or outline-mode; the latter may also be used in Python buffers), getting
an accurate indentation is important even when text is invisible.

I do not understand how ellipsis can be meaningfully accounted for with
regard to indentation. AFAIU, they are not. Try
* something
a
* else
4. Move point to "* <point>something"
5. <TAB> to fold the outline
6. M-: (save-excursion (search-forward " a") (current-indentation))
;; => 10

Maybe. But then I'd like to be able to get the "hard" indentation
information for the underlying text in buffer, accounting for tab-width,
and disregarding overlays and other font-lock staff.
As I mentioned above, this is required for parsing.
Best,
Ihor
