[O] Useful interactive functions for clock logs, and workarounds for large agenda files

2016-07-12 Thread Christoph LANGE
Dear Org-mode community,

I have recently developed a few functions related to clocking and the
agenda, which are highly useful for me.  So far I haven't found the time
to add them to worg, but as I have meanwhile open-sourced my Emacs
configuration, I thought I'd point you there for now.

There is:

1. org-clock-split-current-interval
(stable link to current revision:

This function splits the CLOCK time interval in the current line in two.
 Use case: you logged time on some task but afterwards realise that part
of the time was spent on some other task.  See
for the original description, but meanwhile I have improved the function.

2. org-clock-change-hh-mm
(stable link to current revision:

This function changes the HH:MM parts of the CLOCK time interval in the
current line.  My main use case for this: adding time logged outside of
org-mode to one's org file.  When not at my computer, I log time in an
unstructured way on my phone, e.g. like this:

Tue 12
Taskname 22:00-22:11, 23:31-23:45

(This is mainly because the VimTouch trick explained in
no longer works for me, as on a non-rooted device one can't edit .vimrc
any more.)

I add such logs to my org file by first creating a CLOCK line for the
right day, e.g. copied from somewhere else and possibly changed to the
right day using org-shiftcontrolup, and then modifying the HH:MM parts.
This has so far been quite cumbersome to do manually, as it required me
to jump around a lot in the line.

3. a variant of org-calendar-goto-agenda that does not display an agenda
with the default timespan but always just for one day, bound to the key
"C" in the calendar.  I need this because I'm lazy and keep all my
history in one large org file (5.5 MB, grown over 6.5 years), which
slows down the agenda.
(stable link to current revision:

BTW, I have more workarounds for coping with large agenda files; see
for how to export the agenda of the next month to an external file.  I
also have code for extracting from an org file only those tasks on which
time was logged in a given interval, which is useful e.g. for
(re-)generating clocktables for these intervals.  Please let me know if
you are interested.  This is implemented as a Makefile plus shell and
Perl scripts and is currently hosted in the same private repository in
which I have my org files, but in principle I'm happy to open it.

Hello Philip,

thanks for the answer, but that did not help me, i believe.
I went trough the org-mobile-push with the edebug, but i believe that i 
have to understand how another function that is in there works, maybe these:

(let ((inhibit-redisplay t)
  (org-agenda-files (mapcar 'car org-mobile-files-alist)))

and i cannot start the debugger in the same way on them, as they are not 
startable via M-x.

Does anybody have a clue, what could be the reason, why my agenda is 
normally created but the agendas.org is containing all my agenda view 
but without any headline (todo) in it?

Eval this in your scratch buffer:

(info "(elisp) Edebug")

Then use C-h f org-mobile-push -- the function help buffer contains a
link to the function's source code definition, which you can then
instrument for the debugger by typing C-u C-M-x with point anywhere in
the function definition.

Re: [O] Can I quote/ref value in the output table?

2016-07-12 Thread John Kitchin
Do you mean something like this (I used an elisp block instead of a sql
block, but hopefully you get the idea):

#+name: src-block1
#+BEGIN_SRC emacs-lisp
'((1 2) (3 4))

#+RESULTS: src-block1
| 1 | 2 |
| 3 | 4 |

#+BEGIN_SRC python :var data=src-block1
print data

: [[1, 2], [3, 4]]

If so, give your sql block a name, and use it as a variable in some other

Re: [O] how to speed up an org-mode file?

2016-07-12 Thread Eric S Fraga
My experience is that (non-trivially sized) tables really slow down org
mode, especially if there is more than one in a "section".  I am not
sure why this is, however.

2016-07-12 Thread Leslie Watter
IMHO if you can split the file in more than one .org file you'll get a
better experience.

I've been working on machines with less than 8Gb of ram in files that are
bigger than yours ( 1.2Mb org with lots of latex, R and other things )
and haven't got a trouble.

One thing that 've noticed is that, if I start the whole text shown,
manipulating the file is much slower than if I got only the section I'll
work on at that time. You'll probably should give it a try, e.g. opening
only the section you'll work on.

Thanks, that is a solution but  a bit cumbersome because of the
additional latex file. John sent me a hack which seems a bit more

It seems that the easiest solution is the following

-  run iso-unaccentuate (which runs on regions) on the table, which
   will change Álvarez to 'Alvarez,

-  sort. The sorting is ok

-  reconvert via iso-accentuate the table.

I don't understand much of the org-table sort code. My naive approach would be 

org-table-iso-accentuate and org-table-iso-unaccentuate and then add
that via defadvice to the original function, but that seems a bad
approach since defacvice makes it difficult to debug.

Any suggestions?
