Hello,
As explained in its commit message, the following patch is an attempt at
simplifying `org-show-context' configuration by offering a set of
5 predefined views to choose from instead of setting 4 different
variables (`org-show-following-heading', `org-show-siblings',
`org-show-entry-below' and `org-show-hierarchy-above'). These views are
minimal show current headline, and entry below if needed
local show current headline, entry below and next headline
lineage show direct ancestors and all siblings of current headline;
show entry only if required
canonical show direct ancestors and all of their siblings; show entry
only if required
full show direct ancestors, all their siblings and entry
To sum it up, if original buffer is
* H1
* H2
** Sub 1
** Sub 2
*** Sub sub 1
*** Sub sub 2
Text
*** Sub sub 3
*** Sub sub 4
** Sub 3
and match is on "Text", minimal is
* H1
* H2
* Sub sub 2
Text
`local' is
* H1
* H2
*** Sub sub 2
Text
*** Sub sub 3
`lineage' is
* H1
* H2
** Sub 2
*** Sub sub 1
*** Sub sub 2
Text
*** Sub sub 3
*** Sub sub 4
`canonical' and `full' are
* H1
* H2
** Sub 1
** Sub 2
*** Sub sub 1
*** Sub sub 2
Text
*** Sub sub 3
*** Sub sub 4
** Sub 3
Note that neither `canonical' nor `full' are possible to obtain with the
4 original variables.
"if required"/"if needed" means the entry will only be shown if point is
within the entry (i.e., not on the headline). Thus, for example,
`canonical' and `full' only differ when match is on a headline, since
only latter will show the entry.
I think this is enough, but I can add more views if needed.
WDYT?
Regards,

Subject: [PATCH] Simplify `org-show-context' configuration
* lisp/org.el (org-show-context-detail): New variable.
(org-context-choice, org-show-following-heading, org-show-siblings,
org-show-entry-below, org-show-hierarchy-above): Remove variables.
(org-show-set-visibility): New function.
(org-get-location, org-show-context, org-reveal): Use new function.
(org-link-search): Update docstring.
* lisp/org-agenda.el (org-agenda-cycle-show): Use new function.
Configuration of `org-show-context' is done with a single variable
offering five different views, instead of four variables for a total
of 16 configurations.

I prefer this to the old setup. From a configuration standpoint, it's
much nicer to have all the relevant information in one variable.

Minor: It took me some extra effort to parse this sentence because I'm
not used to seeing 'respectively' used in this way. I think something
like below is more common.
As special cases, a nil or t value means show all contexts in
`minimal' or `full' view, respectively.

Does a single C-u serve a purpose anymore?

Without it, it is `lineage' view. With it, it is `canonical' (but
I forgot to update it). I'm not sure we need the distinction however.
Also, I'm not sure how useful double C-u is.

Question: are the level-1 headlines always visible, all of them I mean?
I know that's the case as of now, but wondered if it'd be good to hide
the ones which are not significant. Not a very sharp advice on this,
though.

My /personal/ preference is to see the ancestors, so that I can know
which path lead to the entry, and avoid confusion in case some "sub sub
sections" are repeated in many different "sub sections".
With your proposal, I then only have the choice between `lineage',
`full' and `canonical', while I'd like something which would give me:
--8<---------------cut here---------------start------------->8---
* H1
* H2
** Sub 2
*** Sub sub 2
Text
--8<---------------cut here---------------end--------------->8---
WDYT?
Best regards,
Seb

I have no strong opinion about this, but I think it would be odd if they
were invisible. After all, this is the basic structure of the document.

I can add `ancestors' view, which would basically be `lineage' without
siblings.

Yes, that's why I'm not so pushy about it. OTOH, it's nice to hide them
when you have a lot of level-1 sections -- I remember that being asked
here by someone.
But, once again, for me, it's not that important.

That'd certainly be good -- and match my current Org config.
And, if I may, to be sure we are somehow "symmetrical", it'd be good to
have as well:
--8<---------------cut here---------------start------------->8---
* H1
* H2
** Sub 2
*** Sub sub 1
*** Sub sub 2
Text
*** Sub sub 3
*** Sub sub 4
--8<---------------cut here---------------end--------------->8---
That is "ancestors" + the siblings of the leaf entry.
Best regards,
Seb

I'd prefer not to do that -- it's easy to get confused, and we've got
narrowing when we need to really focus.

This is the view I'd be interested in having, as well.

Well, I never said it had to be the only (or default) behavior... Just
mentioning that some people express that wish, from time to time.
But I won't push for it.

Actually, the first patch didn't pay attention to children, if any, of
the current headline. Here is a new patch, including feedback from Kyle
and Sébastien.
Considering the following buffer, "Text" being the matched location
* Grandmother
** Uncle
*** Heir
** Father
*** Sister
*** Self
Text
**** First born
Other text
**** The other child
*** Brother
** Aunt
`minimal' is
* Grandmother
*** Self
Text
`local' is
* Grandmother
*** Self
Text
**** First born
`ancestors' is
* Grandmother
** Father
*** Self
Text
`lineage' is
* Grandmother
** Father
*** Sister
*** Self
Text
**** First born
*** Brother
`canonical' is
* Grandmother
** Uncle
** Father
*** Sister
*** Self
Text
**** First born
**** The other child
*** Brother
** Aunt
`full' is
* Grandmother
** Uncle
** Father
*** Sister
*** Self
Text
**** First born
Other text

Subject: [PATCH] Simplify `org-show-context' configuration
* lisp/org.el (org-show-context-detail): New variable.
(org-context-choice, org-show-following-heading, org-show-siblings,
org-show-entry-below, org-show-hierarchy-above): Remove variables.
(org-show-set-visibility): New function.
(org-get-location, org-show-context, org-reveal): Use new function.
(org-link-search): Update docstring.
* lisp/org-agenda.el (org-agenda-cycle-show): Use new function.
Configuration of `org-show-context' is done with a single variable
offering six different views, instead of four variables for a total
of 16 configurations.

i use maint, but looks good. i'd use canonical most of the time.
it would be good to also have semi-canonical [i.e.
canonical-without-ancestor-body-text], where ancestor nodes do not
show body text. text can obscure structure. i use this view for
blogs. otherwise i'd have to make fake headlines just to hide text.
does full show the entry below the headline that point is on? i
wouldn't use this view if it is not canonical [i.e. does not show
children also].
do we presume that the entire buffer's visibility is changed for
showing context, or are things that already shown left showing?

I don't understand. Body text is not shown in ancestors. Considering the
following buffer:
* Grandmother
** Uncle
*** Heir
** Father
Ancestor text
*** Sister
Sibling text
*** Self
Match
**** First born
Child text
**** The other child
*** Brother
** Aunt
`canonical' view is
* Grandmother
** Uncle
** Father
*** Sister
*** Self
Match
**** First born
**** The other child
*** Brother
** Aunt

`full', as its name suggests, shows complete subtree: all children and
their contents.
> do we presume that the entire buffer's visibility is changed for
> showing context, or are things that already shown left showing?
`canonical' change visibilty in subtree, so some parts of it could be
hidden in the process. Other views only augment current visibility.

thanks for showing a complete example.
that is not canonical. i thought we were working from my previous
posts over the years where i used the term "canonical".
you cannot create the visibility state you show from a fully-folded
buffer using only arrow keys and tab.
there are exactly two types of visibility. each type has many
variants in principle, but we only need a few for each.
1] can be created using arrows and tab from a fully-folded buffer
2] cannot
this is a critical distinction.
org so far is not capable of doing any of the [1] states when going to
a location. that's the problem that needs solving imo.
i actually don't care about any of the [2] states until [1] is possible.
within [1], there is a minimal state. let's call it
minimal-canonical. /that/ is the state that is most needed. it's
roughly like what you show except with the body text for all
ancestors.
what you show is [2]. it is a great view, and needed, but it is not
minimal-canonical.
i don't want the term canonical to be used for any of the [2] states,
because then we will be back to missing the need for the
minimal-canonical view and the need for preserving an org buffer's [1]
status.
hope that clarifies.

You are right. Time for a third round, I guess. This patch removes
`full', which is useless, makes `canonical' really canonical, and adds
`tree' view, which is basically old wrong `canonical'.

Subject: [PATCH] Simplify `org-show-context' configuration
* lisp/org.el (org-show-context-detail): New variable.
(org-context-choice, org-show-following-heading, org-show-siblings,
org-show-entry-below, org-show-hierarchy-above): Remove variables.
(org-show-set-visibility): New function.
(org-get-location, org-show-context, org-reveal): Use new function.
(org-link-search): Update docstring.
* lisp/org-agenda.el (org-agenda-cycle-show): Use new function.
Configuration of `org-show-context' is done with a single variable
offering six different views, instead of four variables for a total
of 16 configurations.
