Hi,

I'm new with Scheme and new with org babel so excuse me if I am missing
something obvious.
I have this bit of (simplified) Scheme code to generate a list of lists:

    #+name: chromatic
    #+begin_src scheme :noweb yes
      (map (lambda (x)
     (cond ((< x 4) (list 0 1))
   ((equal? x 4) (list 2 0))
   ((> x 4) (list 1 1))))
   (list 0 1 2 3 4 5 6 7 8 9 10 11))
    #+end_src

It appears to be working fine outputting a table such as

    #+RESULTS:
    | 0 | 1 |
    | 0 | 1 |
    | 0 | 1 |
 ...

For another function in Lilypond, also in scheme I need it to be a (list
(list 0 1) (list 0 1)...) as in the variable seq below:

 #+begin_src scheme :noweb yes
 $(let ((random-state (seed->random-state (current-time)))
       (seq (list (list 0 0) (list 0 1/2) (list 1 0) (list 1 1/2) (list 2
0) (list 3 0) (list 3 1/2) (list 4 0) (list 4 1/2) (list 5 0) (list 5 1/2)
(list 6 0))))
   (make-sequential-music
    (map (lambda (x p)
   (let ((idx (random 12 random-state)))
     (make-music 'NoteEvent
'duration (ly:make-duration 2 0 1/1)
'pitch (ly:make-pitch 0 (car p) (car (cdr p))))))
   (make-list (length seq)) seq)))
     #+end_src

I can do:

(seq <<alist>>)

if alist is:

    #+name: alist
    #+begin_src scheme
      (list (list 0 0) (list 0 1/2) (list 1 0) (list 1 1/2) (list 2 0)
(list 3 0) (list 3 1/2) (list 4 0) (list 4 1/2) (list 5 0) (list 5 1/2)
(list 6 0))
    #+end_src

but what I would like to be able to do is to have have the noweb reference
be to the 'chromatic' function above as in:

(seq <<chromatic()>>)

but that doesn't work. Maybe what I am trying to do is not possible, maybe
there is a limitation on ob-lilypond, but it seems to me that the result of
my function chromatic above spits out ((0 1) (0 1)... ) and that this is
the cause it doesn't work.

Again, I am really new to this...

The workaround I am doing is to format the output of chromatic into a
proper list och lists and then add it by noweb reference.

Any hints welcome.

Newbie question

[Ken]

Hello all,

I am a relative newbie to org-mode. Right now I use it for todo lists, I
use it in conjunction with the diary, and I use it for
journaling/note-taking. I am sure I am only using it fo a quarter or
less of what it can be used for. Anyway, my question is rather simple.
<CTRL-.> will allow you to insert a date. However, in my journal I use a
full timestamp. Is there any way using a defined set of keys to insert a
current TIMESTAMP on an entry (say as in a journal entry)?

Thank you
Ken

Hi Ken,

If you do  <C-u C-c .> you will get an active timestamp with date and 
time. <C-u C-c !> will give you an inactive timestamp with date and time.
I also have this code in my .emacs file, so whenever I create a headline 
I get an inactive timestamp automatically.  It should be easy to change 
to get an active timestamp if you want.

;------------------------------------------------------------------------------
;Creating new headlines insert inactive timestamps automatically

(defun bh/insert-inactive-timestamp ()
(interactive)
(org-insert-time-stamp nil t t nil nil nil))

(defun bh/insert-heading-inactive-timestamp ()
(save-excursion
(org-return)
(org-cycle)
(bh/insert-inactive-timestamp)))

(add-hook 'org-insert-heading-hook 'bh/insert-heading-inactive-timestamp)
;-------------------------------------------------------------------------

Enjoy!

Thanks, Julian. I much appreciate this.

This (and many other questions) is answered in the manual: for this one,
see section 8.2, "Creating timestamps". The manual is available online
e.g.

	http://orgmode.org/org.html#Dates-and-Times

but I generally prefer to look up things locally, using emacs's info
system. For example, evaluate the following in emacs:

    (info "(org) Creating timestamps")

Hi,

I used CUA mode, so my "C-c" is taken up by the "Copy" function.  Is there
some way I can replace "C-c" for org mode with, say, "C-Alt-C" ?

Thanks,
-T
