Hi,

The project's documentation refers to headings and headlines as
synonyms.  Relying on a single definition would be beneficial.  If I had
to choose between the two, I'd go with heading.

If the community finds this valuable, I could prepare a patch.

Thank you.

I agree that consistency would be good and I also think heading is a
better choice than headline.  The former's definition fits what it means
in org; the latter's is more equivalent to a title than anything else.

Agreed.  E.g. no more thinking waste about the question if it is
headline or heading?

There's a problem though.  Function names would have to be changed,
which would have to wait for version 10 otherwise we'd ruin backwards
compatibility.

I think there's little sense in changing the wording in the
documentation alone.

More feedback from the maintainers is welcome.

It doesn't have to break things drastically. When such changes are made,
you would define function aliases using `define-obsolete-function-alias'.
And then that obsoletion warning is removed after a few years.

I see 61 functions with "headline" and 49 with "heading".
So, a near even split. I think it would be a good idea to consolidate this.

We can always use `define-obsolete-function-alias' and give a few years
for people to shift over.

Agreed, we should be consistent across the board.

I feel the need to add that the strongest association with "headline" to
me is newspaper headlines, and I never think of an article having more
than one headline. On the other hand, I don't bat an eye at multiple
headings --- which pushes me towards supporting that as the canonical
term that Org should use.

Just for completeness, definitions of both terms from WordNet:

  heading
      n 1: a line of text serving to indicate what the passage below
           it is about; "the heading seemed to have little to do with
           the text" [syn: {heading}, {header}, {head}]
  headline
      n 1: the heading or caption of a newspaper article [syn:
           {headline}, {newspaper headline}]

I think heading is better than headline - to me headline is a line at
the top of the buffer (like a newpaper headline). Note that in addition
to changes in the manual, it will probably be necessary to make changes
to variable and function names in the code. This may require marking
some old names as obsolete and creating aliases to allow a transition to
the new names and avoid breakage etc.

I enthusiastically support changing the documentation to use heading.
I use heading in my formal grammar because I have found there are more
ways that it can be modified and remain grammatically correct when
used in english sentences. The internal implementation in elisp still
refers to headlines, but changing the docs would be a good first step.
Best!
Tom

I don't really have a strong preference for either but I would love to
remove the cognitive load of wondering whether the name is heading or
header!

Since org requires outline.el, org.el line 4793, why not follow and 
mirror outline.el conventions?

It appears that outline.el uses
`
	"header" for some early set-up(?) functions and

	"heading" for what appears to provide the outline itself.

Furthermore, "headline" shows up only in comments, and only four or five 
times, at that.

After all, org is an, "Outline-based notes management and organize."


Best,

Charlie Millar

I think at this point the community view is pretty clearly in favour of
consolidating "headlines" to "headings".

I think at this stage a patch would be warranted. Should you still be
happy to make one that would be great, otherwise I might try whipping
one up.

I've been looking into changing all the instances of "headline" to
"heading" and I ran into a serious issue: We use `headline' _symbol_ in
multiple places in the code.

Most importantly, org-element.el uses element type `headline' to parse
headings. We cannot easily change this symbol for backwards
compatibility reasons.

I'm afraid that a complete switch to use "heading" everywhere consistently
is not possible without backwards-incompatible change. I know for sure
that changing `headline' element to `heading' element type will break
important packages like org-roam. And there is no good way to work
around this. We cannot make symbol aliases in Elisp in scenarios like
(memq (org-element-type ...) '(headline inlinetask)).

I came to the conclusion that it will, in fact, be easier to change all
things to use "headline" -- all the instances of "heading" in Org code
are in function names, variable names, and docstrings. All can be
changed using obsolete aliases.

On the other hand, overwhelming feedback in this thread is the
opposite -- change "headline" to "heading".

Maybe others have better ideas how to deal with `headline' symbol issue?

And by "easier" you mean "possible", right?  :)

If Emacs Lisp cannot create aliases for symbols, well then it does not
matter what we all like.  Ha-ha!  Still, better to use a "less pretty"
(but precise) term than to have inconsistent naming across APIs.

P.S. We should also harmonize `evaluate' and `execute'; I can never tell
which one to look for when completing.

Please open a separate thread. I am not sure which one is better.
For "execute" vs. "evaluate" we just need to rename function/variable
names and replace in text/docstrings.

I think consistency is the highest priority. Most people preferred
heading, but that was based on the assumption adopting one or the other
was of roughly equal complexity.

Given we cannot change headline to heading without introducing backwards
and external compatibility issues, I would favour just changing to
headline and documenting what deadline defines/means.

FWIW, I'm fine with such a change.  I'm not a native english speaker,
but a "headline" sounds like it's a one-line heading, so it's okay.

I think, from a linguistic perspective, "heading" and "subheading" are more
appropriate than "headline" and "subheadline".

Hi Vikas,

> appropriate than “headline” and “subheadline”.

Unfortunately I’m completely with you (and previous comments here). The meaning
of “headline” is closer to “title” than “heading”. A document can have multiple
headings but only a single headline (which is specifically the line at the top,
e.g. “Newspaper headline”).

As Ihor points out though, from a compat perspective, a change to “heading” may
be intractable. This gives me rather mixed feelings, as I’m of a similar mind
regarding the org-element headline->heading change being too problematic, but
settling on the less accurate term seems quite undesirable too, and doesn’t sit
well with me.

All the best,
Timothy

We cannot make symbol aliases in Elisp but maybe we can support both
symbols for a transitory period during which we warn third-part devs
about replacing the deprecated 'headline symbol?

Given Vikas and Tim feedback, I would rather move forward by changing
"headline" to "heading" *where it does not break anything* then see if
the proposed scenario above is workable.

In this case, I believe it's better to be partially correct (heading
where possible) than to be consistently wrong (headline everywhere) :)

WDYT?

The best idea I can come up with is the following:

1. We replace headline -> heading where it is safe
2. We introduce a new constant: org-element-heading-type, defaulting to
   'headline
3. We use the new constant instead of 'headline element type symbol
4. We announce loudly that 'headline will be deprecated in favour of the
   new constant
5. Few years later, we change the org-element-heading-type value to
   'heading

I tried, but it will be confusing when we talk about Org elements.
Phrases like "Headline element" now make sense as they correspond to the
element type. Changing to "Heading element" while keeping the actual
element as (headline ...) sounds extremely confusing.

That said, we may do what I proposed above and then use
"`org-element-heading-type' element". Somewhat cumbersome, but at least
less confusing.

I think we are needlessly complicating this. We are talking about the
use of a term in an internal code base. While I would agree heading is
more correct, I don't think it is such a big issue to use headline if
that make the transition to a consistent usage easier. When it comes to
code, I think consistency trumps correctness.

If agreement is not possible, my second vote would be for the status
quo. Leave it as it is and focus on more important issues that have a
real impact on users.

I agree. I think the original post was about inconsistency in the
documentation. We should just correct the documentation, use the word
heading consistently throughout, and mention at a prominent place that the
headline symbol is used in the code to parse headings. There is nothing
wrong with that.

Changing documentation means changing function symbols.
Changing function symbols means changing the code.
Changing the code should not reduce code readability, which is of
paramount importance to keep new contributions coming.

That's why I also consider code consistency important.

I think this is okay too, though `org-element-heading-type' might not
be explicit enough: what about `org-element-heading-type-symbol'?

Agree. I was leaning towards having "symbol" in the name as well after
sleeping with the idea.

I looked into this further and I do not think that it is a good idea to
make this change in the coming release. Renaming some things is very too
easy to get wrong and cause failures.
