Evening all,

Has anybody tried adding the functionality of %%(diary-sunrise-sunset)
(sunrise, sunset time and daylight hours) to the google weather code?

I just have something like:

#+CATEGORY: Day/Year
&%%(diary-day-of-year)
#+CATEGORY: Sunrise
&%%(diary-sunrise-sunset)

in one of my Agenda files. Sunrise then appears at sunrise time in my 
Agenda like:

   Sunrise:     6:53...... Sunrise (GMT), sunset 5:52pm (GMT) at 
Wilkesley (10:58 hours daylight)

You need to have some magic fu like:

#+BEGIN_SRC emacs-lisp
   (setq calendar-latitude 53)
   (setq calendar-longitude -2.6)
   (setq calendar-location-name "Wilkesley")
#+END_SRC

in your .emacs so Emacs knows where you are.

Do you have a way to get the sunset located on a line on its own (different
line from the sunrise one)?  That'd be even much nicer...

No, but I would like one:) If there were separate diary functions for 
sunrise and sunset it would be easy. Maybe I need to look at the diary 
elisp and write my own separate functions.

FWIW/YMMV I use RUBY: I like the "twilight" info too--not sure emacs does
twilight info too--maybe you can reuse some of the code and put into

emacs -l .bja-sunrise-sunset-twilight.el

(defun bja-sunrise ()
  "Display sunrise, sunset & twilight information."

Quick hack just parsing the output of diary-sunrise-sunset.

I added this early in my org-config file (which is sourced by .emacs)
- modify latitude, longitude to taste:

--8<---------------cut here---------------start------------->8---
;;; diary supplement - rich in Ca
(setq calendar-latitude 42.3)
(setq calendar-longitude -71.0)
(defun diary-sunrise ()
  (let ((dss (diary-sunrise-sunset)))
    (with-temp-buffer
      (insert dss)
      (goto-char (point-min))
      (search-forward ",")
      (buffer-substring (point-min) (match-beginning 0)))))

(defun diary-sunset ()
  (let ((dss (diary-sunrise-sunset))
        start end)
    (with-temp-buffer
      (insert dss)
      (goto-char (point-min))
      (search-forward ", ")
      (setq start (match-end 0))
      (search-forward " at")
      (setq end (match-beginning 0))
      (goto-char start)
      (capitalize-word 1)
      (buffer-substring start end))))
--8<---------------cut here---------------end--------------->8---

and this to one of my agenda files:

--8<---------------cut here---------------start------------->8---
#+CATEGORY: Weather
%%(diary-sunrise)
%%(diary-sunset)
--8<---------------cut here---------------end--------------->8---

and I get:

Nice!

Is there a way to get this inserted only into the day view, but not  
into the week view? In fact, I would like to have that choice for  
agenda items in general. It makes sense (to me at least) to have more  
information in the day view than in the week view.

Not that I know of, which means one of two things: it's there but I
don't know about it (something that has happened many times in the past
with org) or it's not there and Carsten will have it implemented by
tomorrow morning :-)

PS. FWIW, I'd like that feature too...

That's where I am at the moment, with the weather forecast, sunrise
and sunset times on different lines. I was wondering if the two could
be integrated to make a one line weather forecast, sunrise and sunset
times. ?

eg.
Location: (icon) Chance of Rain, [-1,6] ℃, Sunrise 0658 Sunset 1759 1101 hrs of daylight

Just write your own function to take the individual results and concatenate them, e.g.

--8<---------------cut here---------------start------------->8---
(defun full-catastrophe ()
  (format "%s :: %s" (org-google-weather) (diary-sunrise-sunset)))
--8<---------------cut here---------------end--------------->8---

and add 

--8<---------------cut here---------------start------------->8---
%%(full-catastrophe)
--8<---------------cut here---------------end--------------->8---

to some agenda file.

BTW, I noticed that semicolons followed by spaces cause trouble:

--8<---------------cut here---------------start------------->8---
(defun full-catastrophe ()
  (format "a; b"))
--8<---------------cut here---------------end--------------->8---

puts "a" on one agenda line and "b" in another. It does not happen
if there is no space after the semicolon. And in case you are wondering,
I saw it when trying Ian's (diary-day-of-year) example, which includes "; " in
its output.

Excellent hack, for at least 2 reasons: the feature itself, and showing us the
way how to enhance the agenda... Thanks a lot.

Because of this:

#+begin_src emacs-lisp
    (setq org-agenda-default-appointment-duration 60)
#+end_src

I get:

i.e, a not-that-clear indication of when the sunrise/sunset is supposed to
happen.

In this case, it's clearly a one-minute event. Is there, then, a way to avoid
the "+ 1 hour" range computation for it, while keeping the above variable for
other common tasks?

Not that I know of, but maybe a generalization of the feature that
Konrad was looking for might be what's needed: give properties to agenda
entry generators, so e.g. they cause the agenda entry to be only
displayed today, or to be of a given duration (0 in this case, 10 mins
in some other case, 1 hour by default), etc.  The difficult thing is to
make it general enough, concise enough and undestandable enough for mere
mortals to have a chance.

A clever combination of org-agenda-span and org-agenda-skip-function
(checking against this span) in a custom agenda command should do.

[-- Attachment #1: Type: text/plain, Size: 919 bytes --]

I put the diary-sunset and diary-sunrise functions in a file called
sunrisesunset.el in my elisp directory, it is part of my load path and put
'(require 'sunrisesunset)
in my .emacs
It only loads if I type
M-x load-library   RET   sunrisesunset RET
I am not sure why it isn't automatically loading like other files I have set
the same way, the same holds true for org-google-weather, I ran the git,
have it in my home directory and have it set up for require in my dotemacs
but i still have to
M-x load-library RET org-google-weather RET
to get it to work in my agenda.

I am running on cygwin with emacs 23.2 and with Org 7.4 (updated to make
sure), I ended up putting the diary-sunrise and diary-sunset functions in my
dot emacs and they work just fine but putting the contents of different .el
files in my dotemacs file isn't a good long term solution.  Any suggestions
as to what I might look at or for?

Did you put a

	(provide 'sunrisesunset)

at the end of sunrisesunset.el? That's what tells Emacs that the  
requirement is now fulfilled.

That sounds like a good plan. A property could be used to limit  
visibility to day or week views, and the skip-function would check for  
that property.

Konrad,

Being an elisp noob I had forgotten about the provide code in the .el file.
That fixed that problem, THANK YOU so much.   Now if I can figure out why I
have to
M-x load-library RET google-weather RET
M-x load-library RET org-google-weather RET
to get google weather to work with my agenda (though I am debating on
leaving it this way and having a function load these two files as I am not
always internet connected and it is annoying to wait for the network
connection attempt to timeout 4 times for each day it attempts to retrieve
the weather or maybe I should look and see if I can patch it to make it skip
the other attempts if the first fails? but then I need to figure out how to
get them to load automatically).  I should just need to use the code in my
dot emacs
'(require 'google-weather)
'(require 'org-google-weather)
for it to work but that doesn't seem to do the trick, maybe i need to look
in the code in those .el files.

Bastien,
to your question, I am trying to set some functions in other .el files so
that I can break up differnt parts of code for the different parts of my
.emacs file intsead of just adding more and more code.

You should omit the leading '. With it the lines are equivalent to

(list 'require 'google-weather)
(list 'require 'org-google-weather)

That should be

(require 'google-weather)
(require 'org-google-weather)

without a quote.

Sorry, not sure I was clear enough: my point was that you can *already*
select tasks you want to appear on the dayly agenda view and not on the
weekly agenda view. 

It's just a matter of writing an org-agenda-skip-function that react
differently depending on org-agenda-span.

I leave the homework to someone else :)

Thanks that worked, as I said Noob, somethings get the quote and some
don't.  Now if I can just get org-contacts to load correctly, void variable
value, life will be great.  I think I am starting to get the hang of this
language.

The main thing to remember is that quote inhibits evaluation: 'a gives
you the symbol a whereas a without the quote gives you the *value* of
a. Remember also that in lisp, you call a function func with arguments x
and y like this: (func x y) - this calls the function func on the
*values* of x and y and returns a function value (which of course
depends on how the function is defined). OTOH, '(func x y) is a list of
three elements: func, x and y. So

'(require 'google-weather)

does nothing whereas

(require 'google-weather) 

calls the function require with the symbol google-weather as its argument.

OTOH, the incorrect

(require google-weather)

would call the same function with the *value* of the symbol google-weather
as its argument. Since the symbol has no value, you'd get an error.
Hope this makes things a bit clearer, but there is nothing like getting an
elementary book on Lisp (or the Emacs Lisp introductory tutorial which
should be available in your emacs or online).

As for org-contacts, I just did a git pull (from
git://git.naquadah.org/org-contacts.git) and I was able to load it with
no problems. Also I don't see a variable named "value" in the file, so
either your report of the error is inaccurate or your version is
older. Try the latest version and if you still have problems, checkout
out section 1.4, "Feedback", of the Org manual to find out how to
produce a useful backtrace - then post that to the list.

Right, you "just" need to write a function ;-)

I guess I wasn't clear enough either, because that's what my proposal  
is about as well. My idea is

1) Use some property (or tag) to mark events in an org-file as "day  
view only".
2) Write an org-agenda-skip-function that checks for that property/tag  
AND checks the value of org-agenda-span.

What keeps me from writing that function right now is that I don't  
know the internals of org-mode well enough to know how to check for a  
propery or tag. I expect to spend an hour reading source code, and  
that's for another day :-)

Re: org google weather

The sunrise and sunset strings have been available in the diary
functions for EMACS for a long time; and, the new code above you've
made for inserting them into the weather strings in OrgMode agendas is
great too.  Thanks and I look forward to using it.

Now, is there any simple way, maybe with the (require 'google-weather)
that one can get the "twilight" times too--the 6 degrees of earth
rotation before sunrise and after sunset when there is still sunlight
outside but no sun to be seen? (I like to play soccer at that time
sometimes.)

(I think twilight depends on lat-lon location too though)

Before diving into the code, check out Appendix A, "Hacking", and in
particular section A.9, "Using the property API", in the Org manual.

Thanks for the useful hint! I am not used to code that comes with a  
hacker's manual.

BTW, I found a very simple solution to my original problem of having  
sunrise and sunset only in the day view:

%%(when (eq span 'day) (diary-sunrise))
%%(when (eq span 'day) (diary-sunset))

Fortunately, because apparently org-agenda-skip-function is not called  
for diary-style entries. But I'll continue exploring that approach for  
other types of entries.

That was relatively easy as well:

(defun org-agenda-day-view-only-filter ()
   (let ((subtree-end   (save-excursion (org-end-of-subtree t)))
         (day-view-only (org-entry-get nil "day-view-only" t)))
     (if day-view-only
         (if (eq span 'day)
             nil
             subtree-end)
          nil)))

(setq org-agenda-skip-function-global 'org-agenda-day-view-only-filter)

The agenda items eliminated from the week views are marked with:

:PROPERTIES:
:day-view-only: t
:END:

I put the filter on the global skip function, but others may prefer to  
use a custom agenda view.

Konrad.
