I think the hidden drawers info is useful for users, this should be
shown when org-cycle on headlines.

Here is the patch.

Doesn't this defeat the whole purpose of drawers? What problem do you
want to solve?

Hmm, you're right, my patch seems against the purpose of drawers.

I try to record into under headline. For example, I use "org-contacts.el" which
record people personalized info. I want to see all properties drawer under a
headline when I press [Tab] (org-cycle) to expand it. It's more intuitive.

I agree your opinion. I wonder is it possible to define a buffer local variable
so that user can control this behavior. WDYT?

I think that drawers and headlines are unrelated, and `org-cycle' should
not handle drawers, even through a variable.

However, using `org-show-all' function, you could write a function that
expands properties drawers, and add it to `org-cycle-hook'.

I recall seeing something similar in stackoverflow.
Here it is:
https://stackoverflow.com/questions/17478260/completely-hide-the-properties-drawer-in-org-mode

The accepted answer has a hint how to achieve what your want.

I see. I will add a custom hook config in my personal init.

Yes, my patch added a similar function like `org-show-all' which I borrowed code
from it to `org-cycle-hook'.

Thanks Ihor, I indeed found related code in Org Mode source. I implemented a
similar functionality in my patch.

Oh. I somehow missed your first message...

Now, actually adding something to the discussion.

FYI, there is org-cycle-include-plain-lists variable. If it is set to
'integrate, plain lists will be included into cycling with point at
headline. This is against the logic that org-cycle only needs to be
dealing with headlines. So, I don't see your patch breaking the present
conventions in org.

Yes, this `integrate' value is not great, IMO. However, plain lists have
much more in common with headlines than with drawers.

I still think basic cycling should not include drawers whatsoever. This
is even more true for properties drawers.

Note that you can already display drawers with `org-cycle', using three
prefix arguments.

i wonder if as a companion to such [perhaps hook-based user]

I agree. I use drawers precisely because they contain information I
don't want to see when cycling. Drawers contain 'meta', which is often
tangential to the main content.

I tend to agree about the properties drawers. Cannot come up with a
reasonable use-case for such kind of behaviour.
However, I have some use-case for cycling user-defined property drawers.

In some of my entries, I have long tables storing historical data.
These tables tend to be extremely long and I sometimes hide them inside
a drawer. Opening these drawers (or a customised list of drawers) on
<TAB> would actually make sense for me.

I agree. As I described in my given example "org-contacts", which include person
info in properties drawer. That's why I want to expand when I press "Tab" on
expanding headline. If I see a contact's info with "C-u C-u C-u Tab" is not
convenient.

As for this negation, I can accept.

Is it possible to change "org-cycle-hide-drawers" to "org-cycle-toggle-drawers".
Make it more extendable. Because that function only changed one argument of
"org-flag-drawer". If so some user like me will be easy to toggle hide/show
drawers. (Of course, I don't want to add redundant code in my Emacs init.) If
this is fine, I will re-edit my patch. Remove defcustom option, and hook on
cycle. Only keep changes in "org-cycle-hide-drawers".

I think something is wrong with `org-cycle-hide-drawers' at the moment.
This function was initially meant to be added to `org-cycle-hook' to
re-hide drawers. It should only re-hide properties drawers. In any case,
it is not needed to expand this function, it should be trimmed down to
only take care of property drawers.

What is needed, though, it a tooling similar to block visibility
functions, i.e., `org-hide-block-toggle', `org-hide-block-hall', and,
maybe, `org-hide-block-toggle-maybe'. Regular drawers should get the
same treatment as blocks.

If you look at `org-cycle' code, there is a comment

     ;; Drawers: delegate to `org-flag-drawer'.

This part should be extracted into a new function.

It makes sense if point is on the drawer, and Org does this already.

If point is on a headline, possibly a zillion lines above, it doesn't,
at least not as a common operation.

Well. It's hard to judge for me if my use case is common or not. Since
there are no many other replies in the thread, I have to agree that it
is indeed uncommon.

This sounds reasonable. (I deleted my patch on my local fork, I think your solution is better.)

I found another solution:

Add file-local variable to eval to the Contacts.org file:

#+begin_src org
# Local Variables:
# eval: (let ((current-prefix-arg '(64))) (call-interactively 'org-cycle))
# End:
#+end_src

This is just a workaround. Not very close to my requirement which expand drawers
when press Tab on a single headline. Because this situation only need in
org-contacts or similar things. So I use file-local variables to do it. Maybe I
can define buffer local keybindings to do it better.

Hello,

I pushed the changes. Now drawers folding is on par with blocks. You can
hide or show a drawer with `org-hide-drawer-toggle', which is similar to
`org-hide-block-toggle'. You may want to use it.

Now, visibility behaviour of drawers might be discussed. Currently, all
drawers are "mostly folded", which means that Org tries to fold them
whenever it can. OTOH, blocks are "mostly expanded", i.e., most
operations of the structure of the document opens the blocks. An
alternative would be to have property drawers "mostly folded" and
regular drawers "mostly expanded", i.e., like regular blocks. But that
would partly defeat the "tuck stuff away" feature from drawers.

Another (better?) option would be: "don't mess with folding state" for
regular drawers and blocks, i.e., what is open stays open, what is
closed stays closed. But that's more difficult to achieve. Any taker?

In any case, I think property drawers need to be "mostly folded".

I thought intuitively that property drawers "mostly expanded" and regular
drawers like :LOGBOOK: drawer "mostly folded".

This indeed will be more difficult. I agree. It's not worth to be more complicated.

>
> In any case, I think property drawers need to be "mostly folded".

In my opinion, this design is decided by the usage of properties drawers and
other regular drawers. For now, I only used this two drawers.

For properties drawer, I use them to store meta data. Like org-contacts info,
and URL, Git path, Magit revision link, Author, Email, IMDb, DATE, TIME,
CUSTOM_ID etc. I record those info for review in case of I want to know related
info about current headline's content. For examples:

- - the "DATE" property :: I want to know when I record this headline and content.
- - the "AUTHOR", "EMAIL" property :: I want to know the author name and email.
- - the "URL" property :: I might want to open it if I only record a part of original web page content.
- - the Magit revision link :: I might want to open it when I read the Org content.

About the "LOGBOOK" drawer, I usually record one log entry, or many log entries.
The log entry can be multiple lines, so I can be very long. This long drawer
"should be folder". Instead, the properties drawer is strict to one line as
value, It will not be very long, so should "keep it expanded". This is one
reason too.

I just checked out insert regular drawer keybinding [C-c C-x d]. I think this
should be hidden. Because it is user defined drawers, no one will know how long
it is, and what purpose it is used for. And it's format similar with LOGBOOK.
Not like properties drawer which has property key and value.

On the other side, this properties drawer might be used by some Org related
extensions, like org-contacts, org-drill etc. For org-contacts, the properties
drawer should be expanded, for org-drill, this properties drawer should be
hidden.

At the end, I know this is just my usage experience, this should consider most
Org user's habit of how to use those drawers.

There is no such thing as ":LOGBOOK:" drawers. There are property
drawers, and regular drawers. "LOGBOOK" belongs to the latter.

I think it is worth it, because it is a sane way to handle different
needs.

Property drawers are _internal_ to Org, which means the contents are to
be hidden. You can use property drawers, but think of them as
a database. Seeing the guts of a database is hardly useful. However, Org
provides tooling to read and write it, and even display it (e.g., Org
Colview) without having to expand them.

You may want to expand them to edit them, or simply retrieve
information, it is all text after all, but that's not the intended use
case, so there is no incentive to expand them automatically.

Yes, I use it as a very tiny database. :)

Sure. I have already got the new added functions. I can define a custom advice
