Thank you for the fix of the function org-shifttab in org-version 6.31a.

I wonder how the function org-outline-level is intended to work. Should it show the outline level or count the stars like in org-version 6.31a and one has to take into account `odd' himself to get the outline level when implementing own stuff which use e. g. the function org-shifttab?

org-outline-level shows the number of stars, independently of org-odd- 
levels

Use

    (org-reduced-level (org-outline-level))

to get normalized levels.

Inside org, you need to check which function works with what kind
of level, this is unfortunately not entirely abstracted.

Thank you, exactly what I have missed. Allow me to mention that I would like this hint to be added to the Help documentation of org-outline-level where I looked before.

There is something more with org-outline-level in org-version 6.31a which I still don't understand because I am not aware of some functions used in its implementation. I drilled down the quite special situation to the following file content. I hope that the indentation of x by three spaces does not get lost in the mailing list archive:

-*- eval: (org-mode) -*-
   x

After opening this file and confirming `eval', org-outline-level reports `3' (changes when changing the indentation of x) but I expect it to report someting like `0', `1000' or `1001' or similar like it does with variations like e. g.

-*- mode: org -*-
   x

The function assumes that the cursor is located at the beginning
of an outline heading.  If it is not, it will return garbage.

Ok. I found out that (save-excursion (beginning-of-line) (org-outline-level)) can compensate.

Here I am lost and would like some help. I was not able to find out how to determine if the cursor is on a line with an outline heading or not.

I think you can use the function org-on-heading-p to determine if you
are on a heading or not.

I have troube understanding what you mean.

An outline heading looks like this

*** heading

If the cursor is at the first character of that line, org-outline- 
level will return
3.  If the line looks different, the return value will be badly  
determined (governed by the most recent match of a regular expression  
anywhere in Emacs, might be anything).

If you need to find out, in a lisp program, if you are at the  
beginning of a headline, use

  (and (org-at-heading-p t) (bolp))

I want `3' _independently_ of on which column the cursor is on that line and therefore use (save-excursion (beginning-of-line) (org-outline-level)).

To cover this I use (outline-on-heading-p), without the optional parameter in my case.

The matter is that within any one line I rather want to _ignore_ the column than to _know_ on which column the cursor is.

With all discussed here in this thread combined together I use
(if (outline-on-heading-p)
    (org-reduced-level
     (save-excursion (beginning-of-line) (org-outline-level)))
  '0)))
for my suggestion of heading visibility depth stepping described here

`C-u 2 S-Tab' with `#+STARTUP: odd'

[Michael Brand]

I like the org-indent-mode with the soft-indentation but even more I
like the hard-indentation with `#+STARTUP: odd hidestars' instead for
which I have a question.

This is the content of the example file oddeven:
-*- mode: org -*-
#+STARTUP: oddeven hidestars content
* 1 Org Mode
** 1.1 Introduction
*** 1.1.1 Installation

This is the content of the example file odd:
-*- mode: org -*-
#+STARTUP: odd hidestars content
* 1 Org Mode
*** 1.1 Introduction
***** 1.1.1 Installation

The different _Emacs-faces_ (colors) for the heading levels are the same
when comparing the two files. This Emacs-internal adaptation I
appreciate a lot.

C-u 2 S-Tab shows _two_ levels with the file oddeven but only _one_ with
the file odd. Is this how it is intended to work for the file odd?


org-version is 6.30e.

Re: `C-u 2 S-Tab' with `#+STARTUP: odd'

[Carsten Dominik]

Hi Michael,

yes, I agree it would be consistent to adapt the interpretation
of the prefix arg when using odd-levels.

I have fixed this, it is available in git now, and will be in
the next release (6.31).

Thanks!

Actually, I tested this now, and it works correctly in 6.31.  I don't  
quite
remember when his was changed, but this is implemented already - sorry  
for
nor earlier looking what this really was about.
