Just a normal heading with TODO keyword.


I'm not sure that page really covers the question of how to 
present tasks about

the document within the same document.

Using a normal heading for a task would "commandeer" the 
structure of the

document, which I think is a real problem.

ISTM that there are a few potential solutions:

a. Using inline tasks.  Although not enabled by default, they 
seem to

   solve the problem pretty well.

b. Using commented lines, i.e.

 # TODO: Improve this information.

   Potentially we could even comment Org syntax within the file, 
   like:


 # * TODO Improve this information  :research_needed:

   Which encodes a normal Org heading but as a commented line, 
   so it 	
   wouldn't affect the structure of the document itself.  Of 
   course,
   that would not appear in the exported content, which is 
   probably not
   what we want; but those headings could still be collected, 
   e.g. by

   something like magit-todos.

c. Keeping tasks in a separate file.  We do already have the 
/todo.org
   file, so maybe this is what we should standardize on, i.e. 
   never
   putting tasks in the documents themselves but only in this 
   file.


Here's another potential solution that I find useful.

d. Keeping tasks under a heading held back from export.
I have a capture template that saves tasks about the document 
under a * Tasks :no-export: heading.  To keep the agenda sane, I 
don't add the file.  Instead, I show buffer local tasks with 
org-sidebar.

 The kaobook.cls defines non-standard LaTeX commands for some of 
 its features.  Org mode doesn't know about these, so you'll 
 have 
 to figure out how Org mode can recognize and export them.




I haven't used kaobook, so I can't offer specific pointers.  I 
have used Tufte LaTeX with Org mode, so I can give general 
pointers.


A LaTeX class, such as kaobook, typically redefines standard LaTeX 
commands and environments, and also defines non-standard commands 
and environments.  So, you should first check if your system 
correctly compiles a pdf from the LaTeX examples supplied with 
kaobook.  When the LaTeX side is working correctly, then you'll 
want to identify non-standard commands and environments defined by 
the kaobook class.  In the style and class files you might search 
for \newcommand and \newenvironment, or the documentation might 
identify the user facing non-standard commands and environments. 
These are the ones you'll need to configure specially.


I typically use Org mode macros to insert non-standard LaTeX 
commands.  Here are some I use with non-standard commands from 
Tufte LaTex:


#+MACRO: newthought \newthought{$1}
#+MACRO: sidenote \sidenote[$2][$3]{$1}
#+MACRO: marginnote \marginnote[$2]{$1}
#+MACRO: urlnote \sidenote[$2][$3]{​\url{$1}​}

Non-standard environments are a bit trickier.

First, you might be able to wrap the non-standard environment like 
this in your Org mode file:


#+begin_<>
Something that should be wrapped in <>.
#+end_<>

For figures and tables, you can pass an arbitrary argument to 
:float.  I do this for the Tufte LaTeX marginfigure environment:


#+attr_latex: :float marginfigure :height 1.2in

#+attr_latex: :float marginfigure :options angle=90

#+attr_latex: :placement [ht!] \setfloatalignment{b}

The last example abuses attr_latex to pass a non-standard LaTeX 
command that Tufte LaTeX uses to tweak the vertical alignment of 
the figure.  


Good luck!

Tom

It is actually slightly awkward that built-in babel backends are

Agreed, but the two differ.  With export, the goal is to produce 
code recognized as correct by the target software.  With babel, 
the general goal is to provide language agnostic literate 
programming, which often produces something that meets standards 
of correctness not implemented in software.  The idea of built-in 
babel backends, as distinct from contributed backends, or backends 
distributed by package archive is a function of maintenance burden 
and distribution channel, rather than something intrinsic to the 
backend itself and how it contributes to literate programming.  

However, unless my memory deceives me, Bastien or Nicolas 
previously
voiced against adding babel documentation. Though I cannot find 
the
relevant discussion now and cannot recall the arguments (if

I've found that I can work around the bug by moving the headline

I move it back to its original position, it still unfolds 
properly.  For me, this is easier than my first workaround, which

Possibly related, I intermittently get bits of text following the

this happens when the bug has bitten a folded headline, but if I

+0800/-0800 is

clear enough.

P.S. Last +08/-08 are really time zone abbreviations, not 
offset, however

unlike "BST" & Co. they are acceptable to specify offset
unambiguously.


That is different use case Max. 

For this use case I am in full agreement, that is what is used

worldwide.

What Ihor proposed is time stamp like:

 2023-02-14 Tue 12:00:00 +0800 @UTC

be

zero.

UTC offset exists without time zone.  UTC is absolute time and

They refer to local *solar time* at a particular place.  


Read from:
https://en.wikipedia.org/wiki/UTC_offset

,

Your wikipedia citation puts it like this: "The UTC offset (or 
time offset) is an amount of time subtracted from or added to 
Coordinated Universal Time (UTC) time to specify the local solar 
time (which may not be the current civil time, whether it is 
standard time or daylight saving time)."


Note that the quote distinguishes UTC offset from standard time 
and daylight saving time, which refer to time zones.


This distinction between absolute time (solar time) and space/time

Thomas, I mostly agree with the set of event kinds your 
suggested. Perhaps names
should be justified to have precise and concise terms in UI. 
From my point of
view their value is association with appropriate storage format 
for particular

timestamp.

Agreed.  Another idea for the mobile event is "variably situated 
event".  I don't doubt that better terms might be proposed.


An additional parameter (or sometimes first one to choose) is if 
explicit or
implicit time zone should be used in the file. In the latter 
case the same kinds
of events are possible, particular one is determined from a 
parent scope. User
should be just aware what is actual time zone if it is implicit 
one.


I was trying to capture this in the timestamp, where an explicit 
time zone is indicated and an implicit time zone is simply a date 
and time.


The following concept is aside from event kinds, but might (or 
might not) be
useful to present agenda, to schedule events, to implement the 
feature. Perhaps
a trip may be considered as an ad hoc timezone that follows 
offsets of time in
locations to visit. (Several such ad hoc time zones may allow to 
track schedule
of several people, but it may be too complex to use.) It may be 
considered close
to "mobile" event, but the purpose is not to ensure correct time 
of particular
event. It may facilitate presentation of timeline during the 
trip.


An alternative would be to have headlines for each stop on the 
trip, each of which has a #+TIMEZONE property.  Under each 
headline would be subheads for events, each with a timestamp for a 
"mobile event".  Org would let me toggle the times of these events 
relative to my current location, the event location, and UTC.




Perhaps it is more correct to talk about how events are 
scheduled, not of event
kinds. Consider Christmas and similar events. It is personal and 
local for each
user. If you share your .org file (with specified file-local 
time zone) with
other persons they celebrate accordingly to their local time. In 
addition they
may decide that it should be pleasant for you to receive a 
greeting close to

your local time.


In the first case, "Open Christmas presents at 8:00 AM", the event 
would be variably situated because I want to do this on the years 
I celebrate at home and also the years when I celebrate with 
friends and family in other parts of the world.  A timestamp for a 
variably situated event shares well--the recipient user needs to 
ensure that the event is stored within user's local time zone 
scope.


In the second case, "Send Christmas greetings to Max when he opens 
presents at 8:00 AM" would be an event situated at the place Max 
is celebrating--it is separate from the first case.  If I know 
where Max will celebrate Christmas, then I could use a timestamp 
for a situated event.  Otherwise, I would use a timestamp for a 
mobile event and make certain to ensure that the time zone scope 
for the event tracks Max's whereabouts.


It seems during discussion we use terms in slightly different 
meaning, so I will

try to clarify my point of view.

I had a course on general relativity theory, so "absolute time" 
does make much
sense for me. UTC is just a widely accepted agreement. I was 
bound to Earth
rotation and accumulated some offset from more precise atomic 
clocks. UTC
however currently is easiest way to perform time related 
calculations.


Yes, UTC is the sign we've widely agreed to interpret as absolute 
time.  A key property is that UTC is a continuum, absent the 
potential discontinuities that characterize space/time units like 
time zones.


My perception is still that UTC is one of timezones that may be 
used to specify
event time. It is a bit special since it is used as a reference 
for other time
zones, so it may be preferable for global events. If

It is not ambiguous if the user is familiar with standard time

The representation above is derived from
https://en.wikipedia.org/wiki/ISO_8601, which allows the 
following:


Z

If the time is in UTC, add a Z directly after the time 
without a space.
Z is the zone designator for the zero UTC offset. "09:30 
UTC" is
therefore represented as "09:30Z" or "T0930Z". "14:45:15 
UTC" would be

"14:45:15Z" or "T144515Z".

±hh:mm
±hhmm
±hh

The UTC offset is appended to the time in the same way that 
'Z' was

above, in the form ±[hh]:[mm], ±[hh][mm], or ±[hh].

Negative UTC offsets describe a time zone west of UTC±00:00, 
where the
civil time is behind (or earlier) than UTC so the zone 
designator will

look like "−03:00","−0300", or "−03".

Positive UTC offsets describe a time zone at or east of 
UTC±00:00, where
the civil time is the same as or ahead (or later) than UTC 
so the zone

designator will look like "+02:00","+0200", or "+02".

Not for a casual programmer like me. The timestamp alone might 
easily be read as 11 hours ahead of local time. Nevertheless, Org 
is certainly free to interpret it as relative to UTC.


Are there local references that may confuse users? I mean 
something like 9 hours

ahead of Moscow (Asia/Kamchatka) used in USSR.


I think 9 hours ahead of a timezone with a potentially variable

That is assumption by poster. I do not find it easier.

Right.  The difficulty with scheduling is that it has to take into 
account two time zones in some cases.


Here is a proposal for a terminology of events that honors 
Ramsey's distinction between events and occurrences and hopes to 
cover all of Org's use cases.


* Kinds of event
- No-host event :: An event that takes place at an absolute time. 
Participants must know their local timezone offset from UTC. 
Example [2023-01-23 06:00@UTC].
- Situated event :: An event that takes place at a time local to 
the event site.  Participants must know their local timezone 
offset from UTC and the event site timezone offset from UTC at 
the time of the event.  Example [2023-01-22 Sun 
08:29@Australia/Sydney].
- [Itinerant | Traveling | Mobile] event :: An event that takes 
place at a time local to the event site, which might change after 
the event has been scheduled.  Participants must know their local 
timezone offset from UTC and the event site timezone offset from 
UTC at the time of the event.  Examples might be a regular staff 
meeting that takes place at 9:00 AM wherever the boss happens to 
be, or a proposal to meet with a traveler when it is noon on 
Sunday for the traveler. Example [2023-01-23 06:00].  In this 
case timezone is set according to user timezone preference in 
scope.


The Org user should be able to toggle timestamp representation. 
In the case of a no-host event, user might toggle between UTC and 
local time.  In the case of situated or itinerant event, user 
might toggle among UTC, local time, and local time at the event 
site.

I do not see any point to consider UTC too special.

It is independent of the legislative tampering (DST, etc.) that 
makes timezones difficult to work with.


Both timestamps [2023-01-21 Sat 21:29@UTC] and [2023-01-22 Sun 
08:29@+1100]
specify absolute time. "+1100" means 11 hours, not particular 
location. Do you

have an example of a case where I am wrong?


No, not if +1100 is relative to UTC.

I use the term "time zone" as a set of rules how to calculate 
offset at
particular time moment. UTC is a degenerate case of fixed zero 
offset. 
In this sense "+11:00" is not a timezone, it is time offset. 
Several time zones
(as set of rules) may have such offset at some specific time 
moments including

"Etc/GMT-11" that is a timezone.

This confuses me.  Calculating offset relative to a timezone, such 
as HST, refers to space/time and yields an event.  Calculating 
offset relative to UTC does not refer to space/time and yields 
absolute time.  IMO, using "time zone", which typically refers to 
a region of space/time, to refer to a set of rules that might 
yield absolute time invites the confusion Ramsey was hoping to 
avoid.


A side note. In my opinion, *by default* timestamps should be 
created in

local
time with no offset or timezone. There are should be some 
preferences to

enable
absolute timestamps and a function to fix offsets or timezone 
identifiers for
existing timestamp when the user realizes that they become 
necessary (e.g.

before a trip).

I don't think there should be a default.


Unfortunately hard choice of default value or behavior is

Is there some way for Org to identify when it is likely that user 
has not specified time zone?  If so, a query might be useful.


So I do not see any advantages of UTC in comparison to time 
offset specific

to
particular time zone, usually user's local one. My vote is 
[2023-01-22 Sun
08:29@+1100] and not [2023-01-21 Sat 21:29@UTC] (of course, 
only in cases

when
identifiers like Australia/Sydney do not matter) with a 
configuration option

with timezone used fix offsets in stored timestamps.
The disadvantage of time offset specific to a particular 
timezone is 
that the timezone offset wrt UTC can change arbitrarily. This 
is a potential
problem if the arbitrary change takes place between the 
creation of the
timestamp and the happening it identifies.  In contrast, UTC is 
guaranteed not
to change.  It is not a timezone, it is absolute time, a pure 
continuum.  It

is a requirement of occurrences.


I consider the case when offset is already known because it is a 
time moment in
the past. Besides rare corner cases offset can be considered as 
a part of
authoritative data. Timestamps like [2023-01-22 Sun 08:29@+1100] 
can be

unambiguously mapped to UTC.

Yes, if +1100 is relative to UTC.  If not, then it assumes a 
timezone library that correctly includes the past time.


I'm not sure offset is necessary for events, given that offset 
can change
arbitrarily.  WDYT?  It seems to me that once an event has been 
tied to a
particular time in a particular time zone that Org's job is to 
take into
account changes to that timezone, such as DST and arbitrary 
legislation. 
These changes in the event's timezone need to be propagated 
through the
schedule for each user, so it is possible to synchronize local 
timestamps

around the globe.


For timestamp in the past offsets simplifies calculation of 
duration. Offsets
may be used to fix absolute time before changing location when 
time zone was

omitted. Perhaps I will add more in another part of this thread.

After all, for a person in Berlin [2023-01-22 Sun 08:29@+1100] 
may tell more

than [2023-01-22 Sun 08:29@Australia/Sydney].

For timestamps in the past "absolute" time is almost always

beside timezone identifiers like Australia/Sydney it is possible 
to use
UTC or fixed offset 2023-01-21 Sat 05:55:54 -1000. If a 
timestamp in
future is bound to specific timezone then its identifier must be 
used
since the government may change time offset. Of course there are 
cases
when UTC or timestamps with fixed offsets are used as well: e.g. 
Lunar

eclipse or participants with multiple locations are expected.


Yes, of course!

FYI, lunar eclipse was Ramsey's example of an occurrence, which 
has to do with changes in the relations of things at a time.




So it is "feature" of some timestamps in future that attempt to 
store

them in UTC may lead to their invalidation later.


Yes, these are events, which are relative to a timezone, either 
implicit or explicit.





As to format for storage timestamps in Org files, particular
timestamps may have
or not explicitly specified timezones, but it is unrelated to 
these 3

cases.


I'm curious to learn the classification unrelated to these 
three cases

used to determine when to store UTC and timezone.

...
From my point of view these, 3 cases might be relevant to 
date-time

picker UI,
but not for storage format. While parsing, interpretation of 
each

timestamp
without explicit timezone depends on preferences chosen at 
higher scope.


I'm curious what these preferences are, or might be.


Is the following timestamp is in user local timezone or in UTC?

<2023-02-01 Wed 15:00>

If features like the following is implemented then it will not 
be in

local time zone:
- file-local

   #+TIMEZONE: UTC
   or

   #+TIMEZONE: Australia/Sydney
- subtree-local

   * H1
   :PROPERTIES:
   :TIMEZONE: Australia/Sydney
   :END:

So looking at such timestamp it would be hard to choose 
particular case

from the set you proposed.

This might be a feature, not a bug.  A timestamp that does not 
indicate absolute time (UTC or fixed offset) and does not include 
a timezone relies on the timezone set by user.  So user changes 
timezone preference during trips and these timestamps become 
relative to user's local time.


A timestamp with absolute time or with a timezone would ignore 
user's timezone preference.


Of course it leads to tricky cases when some timestamp is copied 
to a
scope with another time zone. It requires some yank handler and 
text
properties. When timezone is added to a subtree, perhaps, all 
timestamps

inside may need to be changed from implicit timezone.

Perhaps the solution here is to consider this a feature, not a 
bug.  When displaying an event timestamp, the timezone should 
always be indicated.  For an event relative to user, this would be 
the preference currently in scope.  For an event not relative to 
user, the timezone will be part of the timestamp.



For storage format I would use another types
- explicit/implicit time zone
Yes, explicit for events not relative to user, implicit for events 
relative to user.


- Specific timezone/fixed offset. UTC and Etc/GMT-11 zones are 
identical

to + and +1100 offsets accordingly.


Here, absolute time is best, either UTC or fixed offset from UTC 
(don't underestimate legislators' folly changing timezones).


For UI it is better to choose some terms to make the manual and 
UI

dialogues more clear.


Agreed, though I don't have suggestions atm.

I am not a native English speaker and terms "event", 
"occurrence" sounds
confusing for me. E.g. a conference is an event. A regular 
meeting (even
when scheduled in another time zone) or "brush teeth" are more 
close to
occurrence. As soon as you have to split "event" category into 2 
parts
perhaps it is better to pick 3 different names. I may ask for 
fourth
that is absolute, but not UTC, but I would prefer to not insist 
on

namely UTC and use fixed offset instead.

Yes, UTC and fixed offset (from UTC) are two ways of specifying 
absolute time.  Neither one refers to a timezone.



For UI it is meaningful to name
- default time zone for this scope (with a hint if it is 
currently

system-wide, file-local, or specific to subtree), so no explicit
timezone will be set.
- absolute (UTC or fixed offset) preferred for global event
- bound to location (e.g. Australia/Sydney)
- ad-hoc timezone that follows user in their trips (close to 
Ramsey's

"occurrence").


I think the first and last can be considered identical (see 
above).

UTC is not a timezone.  It is absolute time.

Postgres has a reason to insist on UTC since timestamps are 
stored in binary
format as microseconds since epoch. It is important for 
performance and there is
no room to specify offset. Org has to parse timestamps from 
strings anyway, so

it is better to use format more convenient for humans.


Agreed.

A side note. In my opinion, *by default* timestamps should be 
created in local
time with no offset or timezone. There are should be some 
preferences to enable
absolute timestamps and a function to fix offsets or timezone 
identifiers for
existing timestamp when the user realizes that they become 
necessary (e.g.

before a trip).


I don't think there should be a default.  If I'm correct that 
occurrences, events relative to user, and events not relative to 
user exhaustively classify the possibilities, then Org should 
insist that timestamps conform to one of these three 
possibilities.  If the classification is complete, then there is 
no need for a catch-all default.

Yes, to store the time stamp, Org must take it from the event 
time of the
user and translate it to UTC.  When reporting an occurrence to 
the user,
then Org must translate from UTC to the user's space/time. 
User might have
a toggle, like pretty entities, that either shows UTC or 
translation to

user's space/time.


That is right. I have stated same.

How do you want Org to know that user's time is in X time zone? 

It means, that new settings, variables, functions, must be 
introduced
to handle it properly. Timestamp like this one: <2023-01-21 Sat 
09:55>
at HTML export will be from 95% and upwards incorrect. To be 
correct,
time zone designation shall be placed in HTML export. User could 
be in
South America, not in London, that exports it. Time zone UTC 
does not

apply for South America. Representation is wrong.

When you say that Org must take it from the event time of the 
user,
that means that Org must take some parameter to understand what 
time

zone user was.

That means involving functions for export, or sharing of Org 
files.


In general, we speak about representation.

You may start making distinctions between "events" and 
"occurences",
but technically we speak of time stamps which lack relation to 
time

zone in Org. Whatever you "time stamp" without time zone,
representation of it in other time zone becomes difficult, as it 
lacks
the fundamental designation of time zone where it was recorded. 

And it does not matter if user records time zones in UTC, or 
other

time zones.

Here is a distinction that I think is important based on Ramsey's 
distinction between event and occurrence: UTC is absolute time and 
not a timezone.  UTC doesn't occupy a region of space/time, as 
does a timezone.  This is why UTC can be used to generate 
synchronous times for occurrences, but timezones are required to 
generate synchronous times for events.

I understand you got your context specific terminology, from the
mentioned book, where you are making philosophically different
distinction between occurence and event as opposed to 
distinction by

its ordinary meaning in English.
Ordinary meanings are often polysemous, so context is important. 
A big part of philosophy is limiting the confusion caused by 
polysemy. Ramsey was specifically concerned to distinguish two 
senses of the word event because he was certain that using event 
with this polysemy would sow confusion.   


What really matters
---

What matters is aid to users' life.

When arguing, try to make a checklist and TEST it:

- [ ] can user easily understand the time displayed?

- [ ] can user relate the displayed time to his local time 
without

  hesitation?

- [ ] is that program that programmer creates beneficial to user 
or to

  programmer, or theoretician of absolutes, rights and wrongs?

How to test it?

Usability Testing 101:
https://www.nngroup.com/articles/usability-testing-101/

I'm hopeful that Ramsey's distinction between event and occurrence 
contributes to what really matters.  How that distinction is 
communicated to the user most effectively is an open question, 
IMO.




Today there is in computing pretty much agreement that:
---

- All computer time should be stored to UTC, UTC being basis for 
any

  other computations

- System libraries have (or should have) various configurations

- Computer users should be shown their local time

I was thinking that Org timestamps should record the information 
needed to let Org calculate user's local time so it is synchronous 
with other users' local times. This ought to make it possible to 
take into account unforeseen, arbitrary changes in timezone (as 
when a legislative body imposes or rescinds DST) that take place 
between the time an event is scheduled and when it takes place. 
Using absolute time (UTC) stored before the arbitrary change in 
timezone will cause problems.  Of course, arbitrary changes in 
timezone do not affect an occurrence, so storing UTC in this 
instance is correct.




* Overview of noun occurrence
-


The noun occurrence has 2 senses (first 2 from tagged texts)
1. (29) happening, occurrence, occurrent, natural event -- (an 
event that happens)
2. (3) occurrence -- (an instance of something occurring; "a 
disease of frequent occurrence"; "the occurrence (or presence) 
of life on other planets")


* Overview of noun event

The noun event has 4 senses (first 2 from tagged texts)
1. (62) event -- (something that happens at a given place and 
time)
2. (6) event, case -- (a special set of circumstances; "in that 
event, the first possibility is excluded"; "it may rain in which 
case the picnic will be canceled")
3. event -- (a phenomenon located at a single point in 
space-time; the fundamental observational entity in relativity 
theory)
4. consequence, effect, outcome, result, event, issue, upshot -- 
(a phenomenon
that follows and is caused by some previous phenomenon; "the 
magnetic effect was
greater when the rod was lengthwise"; "his decision had 
depressing consequences

for business"; "he acted very wise after the event")


Yes, you can see all the polysemy.  Also, you can see why Ramsey 
was happy with event, and less so with occurrence.  The important 
point is the distinction he proposed, not the words used to 
express it.  I think the distinction is germane to understanding 
what information is needed to let Org calculate user's local time 
so it is synchronous with other users' local times.  To my mind, 
it helps bring order out of complexity.

Or, it might be a recurring virtual meeting that the boss wants

I believe that some manual action is required in this case 
anyway. You almost
certainly already have 9:00 AM in your agenda as a reoccurring 
timestamp either
with implicit or explicit timezone of usual presence. For the 
period of the trip
it is necessary to add series of meetings with explicitly 
specified timezones
(UTC or locations during the trip). Another approach is to 
define ad hoc "boss"

timezone and update it to reflect all trips.


Agreed.  The boss needs to inform you what her local time will be 
for the meeting by sending you a timestamp with a time zone. 
Ideally, Org would know how to associate the timestamp with a 
recurring item stored locally.




At the Org side it might be support of multiple ad hoc 
"timezones": a one for
you personal trips and several ones for people you frequently 
communicate with.
It is a nice option, but might be too complicated for usage. It 
may be easier to
suspend regular entry and to add custom ones with no 
requirements related to the

code. Anyway it assumes some communication between participants.


Nowadays, I am frequently asked by applications to give permission 
for using my location.  When I give it, the application reports 
back with my local postal code, etc.  I'm assuming Org can use 
location to determine my current timezone.

Event not relative to user, where the timestamp includes the

I would argue case 2 is really just a specialisation of case 3 
i.e. it
has an implicit time zone which is the user's local time zone. 

Case 2 covers things the user wants to do at a particular time, 
regardless of where they are and the time zone they are in.  For a 
repeating task the time zone might change from one instance to the 
next.  It needs to follow the user around and can presumably rely 
on software to keep track of that.


For completeness, Case 3 might benefit from a procedure to 
change the relevant time zone.
For instance, when the boss has scheduled time for you at 9:00 
AM her time, but doesn't

know where she will be on that day.



If it is to be a fact-to-face meeting (event), implying it 
therefore has
a location, you would assume your local time zone. If not 
face-to-face
(occurrence), it needs a UTC offset in order to ensure same 
point in
time for all participants. The boss either needs to specify the 
time
zone they are referencing the 9am to or the user will need to 
make a

guess, which may or may not be correct.


Or, it might be a recurring virtual meeting that the boss wants to 
initiate at 9:00 AM her time, regardless of the time zone she 
happens to inhabit, as might happen on a business trip.  Here, the 
virtual meeting is an event because the boss relates it to her own 
space/time.  Inconvenient for employees, but some bosses are like 
that.  Here, the time zone needs to follow the boss around.


My current hypothesis is that the three cases are exhaustive.

Good example!  Thanks for the link.

cases for timestamps associated with meetings.
1. A meeting timestamp for a meeting where all the participants 
are in

the same time zone.
...> 2. A meeting timestamp for a meeting where all the 
participants are in

different time zones


Tim, every scheduled meeting event is associated with some 
particular time zone,

often implicitly. So it is single use case.

It is up to participants to negotiate which timezone is the 
primary one for each
event. It is matter of people communication, not technical 
issue.


First Monday 15:00 is (almost) equally precise for
- Australia/Canberra having DST
- Australia/Darwin where currently no DST
- +1000 (the highest chance of improper use unfortunately)
- UTC

Aside from time transition intervals, it is possible to take any 
of this variant
and to present time local for other participant across the 
globe.


Storage timezone may differ from the current user preference 
which time zone

should be used to display timestamp or to export it.

The problem arises when several participants believe that their 
timezones are
primary ones and they do not sync their schedules through a 
shared file or a DB
entry. An application can not solve this problem, but it might 
try to help to
identify it. Some efforts are necessary from user side. 
Timestamp should contain
list of timezones of other participants and cached local time. 
In such case an
application may warn users that local time values become 
inconsistent due to DST
transitions or due to update of time zone database. Unsure to 
what degree it

should be implemented in Org.

So
- It is participants fault if a meeting is not associated with 
particular

 timezone
- Having a fair time handling library, it does not matter what 
time zone is used

 to schedule the meeting.


Or, one can recognize that the meeting is an occurrence that 
requires absolute time and a timestamp with UTC.  Each participant 
will resolve UTC to the local time where they happen to be when 
the meeting takes place.  The user might toggle between UTC and 
the local time translation using overlays, like pretty entities. 
This avoids the problem of negotiating a timezone caused by 
forcing an occurrence to be represented as an event relative to a 
fictitious space/time.

Agreed.  It does seem irrelevant for time zone libraries.

requires absolute time.  Meetings,
which involve a change in relation among participants, are 
occurrences.  IMO, this
indicates Org should give occurrences a UTC timestamp, then 
translate that for each of the

user's space/time.  Time here
is relative to the user.  IMO, this means that Org should give 
events a timestamp without
reference to either absolute time or a particular time zone, 
like the one it uses now.




Just checking if I understand. I think we are coming from the 
same

position and with the same conclusion.


Thanks!

In the situation where the meeting involves people from 
different time
zones, the time of the meeting as reported by org needs to be 
adjusted
after a daylight savings transition so that the time maintains 
the same

relative to UTC. i.e. meeting time reported in local time goes
forward/backward 1 hour depending on the daylight savings 
transition
(in/out). I guess this is what you call an occurrence? 

When all participants in a meeting are in the same time zone, 
you do not
want the time changed as the result of the daylight savings 
transition.

This is what you call an event?


Every meeting is an occurrence because it involves changes in 
relations of things at time; in this case meeting participants 
relate to one another via Jitsi, regardless of whether they are 
all in one time zone or spread over the globe.


An event's time is relative to the user's location, or space/time. 
So, the example I gave earlier "Brush teeth before bed" set to 
10:00 PM, which works whether I am home in Honolulu or enjoying 
the hustle and bustle of Manhattan, is a simple event.  It happens 
at that time in the timezone I happen to inhabit at the moment, 
because I intend to go to sleep shortly after 10:00 PM regardless 
of where I am.




So, using your terminology, what we now need is convenience 
functions
for setting an occurrence timestamp and an event timestamp. I'm 
not sure
if occurrence/event are the best terms, but I cannot think of 
better
ones. Just slightly concerned people will have trouble grasping 
the
difference and undersanding why some meetings are an occurrence 
while
others are an event. FOr the user, they are just meetings.


Yes, both meetings are occurrences.

I agree that the terms take some getting used to.  I got them from 
Frank Ramsey, who seemed to be happy with event, but not so happy 
with occurrence.


The difference is this: Will the happening being scheduled involve 
other people, who will share the Org timestamp, or will it take 
place at the same absolute time, regardless of where you are when 
it happens?  If so, then the timestamp should be stored as UTC (it 
is an occurrence that requires absolute time).


Or, is it something you want to do at a time, regardless of where 
you are.  If so, then the usual Org timestamp without UTC is what 
should be stored (it is an event that requires time local to the 
user).


In the case of a meeting, where the one who calls the meeting 
sends an Org file with a meeting agenda and a UTC timestamp to 
each of the participants, Org will translate the UTC timestamp 
into local time for each participant.  Similarly, when you are 
traveling, Org will translate the UTC timestamp to the timezone 
you happen to inhabit.  Here, I'm assuming that the timezone 
machinery is capable of determining local time relative to UTC.

User in Grece needs appointment at 9 o'clock, and writes it as:
<2023-01-20 Fri 09:00> He also has TIMEZONE (either system or 
Org file
based) set to "EET". That way the time has been recorded in UTC 
for
Org purposes, and UTC has been solved. For Greek user it is 
completely
solved. Org calculates UTC based on configured time zone. But 
when it

is 16:00 o'clock in Greece, it is 06:00 in Seattle.

Online appointment is sent to user in Seattle, with the time 
zone
PST. He receives the Org file from Greece, at 8:00 o'clock, 
which has
settings inside TIMEZONE="EET". At first user thinks that 
appointment
is in just 1 hour, because he can see "08:00", but Org 
gracefully
notifies user that appointment is (probably) in a different time 
zone,
and asks user if user would like to have it displayed in PST 
time
zone. User answers with "Yes" and on his screen appears that 
meeting
is actually at <2023-01-20 Fri 23:00>, he prepares himself for 
longer

evening, and waits for his Greek partner on Jitsi Meet:
https://meet.jit.si/ to get online.

It confirms your hypothesis, yes, all times are calculated as 
UTC, but
all time stamps at export, sharing, or change of time zone, 
shall be

displayable in understandable manner to human user.

Only occurrences require absolute time, UTC.  Events do not.  They 
follow the user's space/time.



> Org in this state can't handle such things.

Org can do the useful thing: translate the UTC timestamp into 
local time and
report both UTC and local time.  User will be able quickly to 
determine if

local time is incorrect for some reason, such as DST or travel.


Other way around, it has to translate time stamp into UTC time 
in the first place. 


Yes, to store the time stamp, Org must take it from the event time 
of the user and translate it to UTC.  When reporting an occurrence 
to the user, then Org must translate from UTC to the user's 
space/time.  User might have a toggle, like pretty entities, that 
either shows UTC or translation to user's space/time.


Expecting that all user among so many various time zones write 
their
time stamps in UTC is not reasonable. Org users are advanced, I 
know,
but majority of note takers with other applications will not 
even
think of different time zones, it is surprise they get when 
dealing
internationally. People are not ready for calculating or even 
viewing
their own time in UTC time zone, unless they are English or 
Icelandic,

Portuguese, or Africans in parts of the West Africa.

Org should translate from the user's space/time to absolute time, 
UTC.  The user has to tell Org what is the space/time relationship 
to absolute time.  Org might use the timezone machinery to suggest 
a space/time relationship to absolute time, and it might warn the 
user when the user's suggested relationship differs from the value 
reported by the timezone machinery.



Storing timestamps in UTC solves the interval problem Ihor
raised. Intervals always make sense in absolute time.  Moving 
them

to event time leads to the insanity Ihor mentioned.


The other way around. Assuming that time stamps are UTC raises
problems for all other people:
https://upload.wikimedia.org/wikipedia/commons/8/88/World_Time_Zones_Map.png

Org now does not support time stamps, right?

So people write timestamps in their own time zone! Is it right?


IIUC, Org currently stores events, which are relative to the 
user's space/time.  This works for events, but breaks for 
occurrences, which require absolute time, UTC.




My time stamp here is <2023-01-19 Thu 17:12> now, what is yours?


<2023-01-19 Thu 06:08>  This is an event, specified relative to my 
space/time.




Forcing users to write time stamps in UTC would cause havoc.


Agreed, Org should help.



Thus time stamps already have their time zones, it is just not
recorded in Org file. 


Events don't need a time zone, only occurrences need absolute 
time.




Options can be created so that:

- user always and automatically record time zone in Org file, 
for
  example from system time zone, so that when first time 
  property is

  invoked that it stays there:

#+TIMEZONE: EET

Or like this

* TODO Appointment on Jitsy Meet with Greek investor
  DEADLINE: <2023-01-20 Fri 09:00>
  :PROPERTIES:
  :TIMEZONE: EET
  :END:

or inside of the time zone.

When such heading is read in Seattle, Washington, Org will tell 
to

user or ask to translate it to PST time.

In such translations, EET time is first converted to UTC, for 
reason

of using system libraries, and not complicating Org, and then
converted to PST time zone.


The Org user in Seattle would either see UTC or toggle to see UTC

Re: [FEATURE REQUEST] Timezone support in org-mode datestamps and org-agenda

2023-01-15 Thread Thomas S. Dye

Aloha all,

IIUC, timestamps in Org might be used to track two things: events 
and occurrences.


An event refers to a particular region of space/time, in Org's 
case the space/time occupied by the user, regardless of which time 
zone the user occupies.  An event might be "Brush teeth before 
bed" set for 10:00 PM, which the user would want to make happen at 
that time, regardless of the time of day in the timezone in which 
the timestamp was applied to the event.


An occurrence refers to changes in the nature and relations of 
substances at a time.  It takes place in absolute time in order to 
avoid circularity.  An occurrence might be "Attend virtual 
meeting" set for 9:00 AM on a certain day, which the user would 
want to make happen at 9:00 AM on that day in the time zone where 
the timestamp was applied to the occurrence, regardless of the 
time zone where the user happened to be.


I found this distinction in a book called On Truth by Frank 
Ramsey, that was unfinished at his untimely death at age 26. 
"Event" and "occurrence" were Ramsey's suggestions.  He seemed to 
like "event", but thought "occurrence" would work, though it might 
be improved.


I enjoy having terms for these two kinds of happenings and I'm 
hopeful you'll find them useful, too.

It's not odd at all.  As we see various activities pushed into 
unjust
computing, which requires nonfree software and online 
dis-services,
remaining free sometimes becomes difficult.  You may have to 
refuse to
do certsin things "everyone" does.  If one of those things 
happens to
be useful for working on GNU, that's not surprising as tyranny 
marches

on.


In this case, I'm having to refuse to contribute to Org mode 
development in the convenient way I contribute monthly to FSF.


I'm hoping this is an odd situation that can be remedied 
reasonably in favor of my convenience, rather than a tyrannical 
situation that defies reason.


Nevertheless, it is good to know that I'm free to give up freedoms 
to contribute to Org mode development.  @Ihor, will Paypal work 
for you?

Thanks for the offer!
I afraid that sending a check to me specifically is not a good

especially from a person based in USA.

I know little about depositing received checks, so I had to 
search
through my bank website in China (I have no access to my

close to

200USD [1] for collecting checks.

As you can see, there is little point sending me checks.

Probably, USA->China is a bit extreme case, but, as I can see, 
bank fees
are not uncommon for checks. Thus, small donations are likely 
impossible
via check. Now, I feel like even the available free donation

not really suitable in practice for reasons unrelated to free 
software.


Yes, your Chinese bank charges exorbitant fees for cashing US 
checks.  That won't work.


It seems odd that our embrace of software freedom should keep us

Keep up the good work in any case!

Neat!  Converting Word documents is no fun at all.

Haskell code blocks

2022-01-02 Thread Thomas S. Dye

Aloha all,

Happy New Year!

I'm struggling to write a minimal ob-doc-haskell.org for Worg.

I installed Haskell via Spacemacs (development branch) and the 
Haskell installation appears to be functioning correctly.


The obligatory Hello World! example yields bad results.

#+name: haskell-hello-world
#+begin_src haskell 
main :: IO () 
main = putStrLn  "Hello, World!"

main
#+end_src

#+RESULTS: haskell-hello-world
: Prelude> Hello, World!

I'm guessing the "Prelude>" part of the output is the prompt from 
the interpreter.


I found this in ob-haskell.el:

 (setq-local comint-prompt-regexp
 (concat haskell-prompt-regexp "\\|^λ?> 
 "
 
But I couldn't find a way to modify haskell-prompt-regexp without 
changing the source.


Advice welcome.

This is probably the path of least resistance for users who want to use 
biblatex-chicago out of the box, rather than as a basis for deriving a specific 
style.

Here is the relevant section 4.51 of the biblatex-chicago manual:

 With the addition of the author-date styles to the package, I 
 have provided three keys for choosing which style to load, 
 notes, authordate, and authordate-trad , one of which you put in 
 the options to the \usepackage command. The default way of 
 loading the notes + bibliography style has therefore slightly 
 changed. With early versions of biblatex-chicago-notes , the 
 standard way of loading the package was via a call to biblatex , 
 e.g.:


 \usepackage[style=chicago-notes,strict,backend=bibtex8,%
 babel=other,bibencoding=inputenc]{biblatex}

 Now, the default way to load the style, and one that will in the 
 vast majority of standard cases produce the same results as the 
 old invocation, will look like this:


 \usepackage[notes,strict,backend=biber,autolang=other,%
 bibencoding=inputenc]{biblatex-chicago}

 (In point of fact, the previous biblatex-chicago loading method 
 without the notes option will still work, but only because I’ve 
 made the notes & bibliography style the default if no style is 
 explicitly requested.) If you read through biblatex-chicago.sty, 
 you’ll see that it sets a number of biblatex options aimed at 
 following the Chicago specification, as well as setting a few 
 formatting variables intended as reasonable defaults (see 
 section 4.4.1, above). Some parts of this specification, 
 however, are plainly more “suggested” than “required,” and 
 indeed many publishers, while adopting the main skeleton of the 
 Chicago style in citations, nonetheless maintain their own house 
 styles to which the defaults I have provided do not conform.


 If you only need to change one or two parameters, this can 
 easily be done by putting different options in the call to 
 biblatex-chicago or redefining other formatting variables in the 
 preamble, thereby overriding the package defaults. If, however, 
 you wish more substantially to alter the output of the package, 
 perhaps to use it as a base for constructing another style 
 altogether, then you may want to revert to the old style of 
 invocation above. You’ll lose all the definitions in 
 biblatex-chicago.sty, including those to which I’ve already 
 alluded and also the code that sets the note number in-line 
 rather than superscript in endnotes or footnotes. Also in this 
 file is the code that calls cmsamerican.lbx , which means that 
 you’ll lose all the Chicago-specific bibstrings I’ve defined 
 unless you provide, in your preamble, a \DeclareLanguageMapping 
 command adapted for your setup, on which see section 7 below and 
 also §§ 4.9.1 and 4.11.8 in biblatex.pdf .


 What you will not lose is the ability to call the package 
 options annotation, strict, short, and noibid (section 4.4.3, 
 above), in case these continue to be useful to you when 
 constructing your own modifications. There’s very little code, 
 therefore, actually in biblatex-chicago.sty , but I hope that 
 even this minimal separation will make the package somewhat more 
 adaptable. Any suggestions on this score are, of course, 
 welcome.

After some thought, it occurs to me that it is likely a bad idea

source code blocks that might prove useful to Babel users.


Perhaps there is some way to indicate that this file just needs to 
be copied "as is" when Worg is published?  Or, if not, then 
perhaps the patch with the ungainly, working URL might be applied 
to the manual?

them to be enough.  Here's where I might have spent more time in

that I can dance around a page of text, in a manner that the

the way
one can move back and forth over characters and words.  I never 
learned Vi,

except to be able to edit a simple config file if need be.

I know I am over my head, and I have been so for the 30-ish 
years I have
been using Emacs and for the time I have used Org-mode.  It is 
more than I
can do to keep up with the newer complexities that are cropping 
up.  Yet,

just like the plain text files, and the LaTeX source for my one

through all
the changes, my little utilities for editing things that only I

still work today.  I love it!


FYI, from another old-timer in over his head, Spacemacs has a simple option to 
enable Emacs key bindings.  You don't need to use the modal bindings.

It is great that the problem is solved. I do not think however

If I export both, then all is well.
#+begin_src emacs-lisp :results value none :exports both

   'org-babel-load-languages

I feel that I have missed something. I do not see the purpose to

source block in user docs. I expect that for accidental usage it 
is more
convenient to type (require 'ob-org), while as a permanent 
settings it is
possible to do customize-variable org-babel-load-languages or to 
use

`add-to-list'.


The source block is included to show the user how to modify their 
.emacs.


I was surprised that changing its :results header argument had an 
effect on export.


Do you have an explanation why the header argument makes this 
difference on Worg?

#+begin_src emacs-lisp :results value none :exports results

#+begin_src emacs-lisp :results value none :exports results

  Hello, $hello!

support for ":dbconnection". I can set up an entry in

give the name of the entry to the sql block via :dbconnection.

Re: [BUG] Source code of type 'conf' disappears in LaTeX export [N/A (N/A @ /usr/share/emacs/site-lisp/org-mode/)]

2021-10-29 Thread Thomas S. Dye

Aloha,

Marc van der Sluys  writes:

Remember to cover the basics, that is, what you expected to

what in fact did happen.  You don't know how to make a good 
report?  See


 https://orgmode.org/manual/Feedback.html#Feedback

Your bug report will be posted to the Org mailing list.

Thank you for the incredible orgmode software!

I ran into this issue.  When I have a block of 'code' from a 
configuration file, e.g.


#+begin_src conf
  Host server
   HostName servername.domainname.org
   User username
#+end_src

it shows up nicely in emacs.  However, when exporting to LaTeX 
and pdf using the Minted package, the code blocks go missing 
completely.  The code is converted in LaTeX to


\begin{minted}[]{conf}
Host server
 HostName servername.domainname.org
 User username
\end{minted}

which disappears upon compilation because 'conf' is not one of 
the lexers recognised by Minted.


Replacing 'conf' with 'aconf' (for Apache config) has the 
opposite result: no syntax highlighting in emacs orgmode, but 
acceptable output in LaTeX, because it is supported by Minted.


A 'quick fix' could therefore be to either:
  1) rename conf -> aconf when exporting orgmode to LaTeX,
or
  2) adding the syntax highlighting that is used for conf to 
  source blocks of type aconf.



Expected behaviour:
+ conf code block shows up in LaTeX/pdf with syntax highlighting 
after converting from orgmode to LaTeX/PDF.


Actual behaviour:
+ conf code block completely disappears in PDF after converting 
from orgmode to LaTeX/PDF.



Sincerely,

Marc van der Sluys.

Similar past for me as well. I used vi from early/mid 80x until

and then switched to Emacs and used standard Emacs bindings

I realised when I did I had very much missed the vi modal

approach. I know it isn't for everyone, but I find using it 
pushes my
productivity through the roof. I always tried to use keyboard 
navigation
and avoid the mouse. Being able to use simple keys rather than 
complex
bindings involving ctl, alt, shift, is just so much faster and 
easier on
my aging and stiffining fingers, I think I'm now a devout member 
of the

evil-mode cult.


Same here, though Spacemacs introduced me to modal editing.

Spacemacs also helped eliminate many of my rookie errors 
configuring Emacs.
