Passing font size to exported LaTeX table

Passing font size to exported LaTeX table

[John Hendy]

[-- Attachment #1: Type: text/plain, Size: 470 bytes --]

Hi,


I can control a table font size directly from the .tex file like so:

---
\scriptsize{
\begin{center}
\begin{tabular}{lllrr}

table entries here

\end{tabular}
\end{center}
}
---

Any way to pass this from org-mode? Otherwise, I keep changing the org file,
exporting, and then having to add this to the tex file and re-export.

I tried:
---
#+begin_latex
\scriptsize{
#+end_latex

|org|table|here|

#+begin_latex
}
#+end_latex
---

without success.


Thanks,
John

You put the things in the wrong order:

1. put a group around some LaTeX commands
2. add the macro \scriptsize in it

Hence:

#+begin_src org
  #+begin_latex
  {\scriptsize
  #+end_latex

  |org|table|here|

  #+begin_latex
  }
  #+end_latex
#+end_src

should do it (not tested).

Best regards,

I'm getting this error upon export (no PDF created):

I'm assuming something is not liking that dangling "}"...

Thoughts?

I didn't try Seb's workaround but your original solution almost works:
what stops it is YAB in the latex exporter, but having been bitten by
such a couple of times in the past, I applied my usual[fn:1] workaround
and presto! it works:

,----
| 
| * foo
| 
| #+begin_latex
| \scriptsize{ %}
| #+end_latex
| 
| #+tblname: foo
| | table | here |
| |-------+------|
| | table | here |
| 
| #+begin_latex
| }
| #+end_latex
`----

The opening brace on the \scriptsize line confuses the exporter and it
leaves the table alone. Adding a commented-out closing brace unconfuses
it.

Awesome!! And now I recall seeing it before on the list. Very cool.

Perhaps -- the tough things is that an issue with braces is not what I would
have expected the problem was. I thought I just wasn't combining things
right or that the org exporter was making something like this impossible
based on how it parsed the text. In any case, yes, it would be cool to have
in public written somewhere. Thanks!

Aloha all,

This appears to work for tabular environments only.  When I add a
caption the table is set normalsize and the text following it is set
scriptsize. Or, am I doing something wrong?

All the best,
Tom

Oy, vey: I don't think you are doing anything wrong - I get the same
thing.

Can \scriptsize be used as a macro with argument? I don't have
my references here.  If I do it the way Seb suggested, inside an
environment, it seems to work better, in the sense that it does not
change the thing after the table - but the table is unaffected
nevertheless. I guess the table environment sets a font size explicitly,
overriding outside settings.

table -> float -> xfloat -> floatboxreset -> normalsize

So you can redefine floatboreset to change the size:

scripttab.sty:
--8<---------------cut here---------------start------------->8---
\makeatletter
\def \@floatboxreset {%
        \reset@font
        \scriptsize
        \@setminipage
}
\makeatother
--8<---------------cut here---------------end--------------->8---

scripttab.org:

This was supposed to say that yes, indeed, the table environment sets

What's this?

What's this?

I think this works OK.

Although this is solved now, I found a very simple solution.

e.g. for footnotesize just add the line:

#+ATTR_LaTeX: placement=[<options>]\footnotesize

Of course you may. :) I came across a few very nicely written articles
by LF Mori in The Practex Journal. This particular solution was
discussed in section 3.1 of the following article:

Aloha Suvayu,

Thank you for the link to the Mori article.  It is nicely written.

My question was poorly written, though.  I'm interested to know where
you found the Org-mode line:

#+ATTR_LaTeX: placement=[<options>]\footnotesize

I haven't been able to find this solution anywhere else.

All the best,
Tom

I got the solution by reading between the lines and some
experimentation. The placement option is documented in the section
referenced below[1]. Note that this does not say anything about tables.
I think I found it by experimenting that this also works for tables.
When I saw the LaTeX solution in the article I mentioned earlier, I
tried out and found exporting as above works. :)

Aloha Suvayu,

I think #+ATTR_LaTeX: needs more documentation.  I worked very hard to
read between the lines of the Org-mode manual to arrive at your simple
solution but didn't manage to come close!

Are you able to summarize the possibilities of #+ATTR_LaTeX?  I'm
thinking that a general description somewhere in the Org-mode manual
might be useful.  It would probably also be good to augment the existing
descriptions of its use in the manual, as well.  Perhaps it would be
possible to propose a patch to the documentation?

All the best,
Tom

I am not very familiar with org-latex internals. Based on my limited
understanding I wrote the attached patch to the org manual. I hope it

Aloha Suvayu,

This looks like an improvement to me.  I'd be interested to hear what
Nick and Seb might have to say.  They often catch things I miss.

If you don't get other comments, I'd encourage you to submit this as a
patch (I think this requires [PATCH] in the subject line) to see what
Carsten and crew have to say about it.

Thanks again for finding this solution to specifying the font size for
floating tables on a table-by-table basis in LaTeX export.  I'd been
looking for your solution, and for Nick's solution that works on a
per-document or buffer basis, for many months without success.

All the best,
Tom

I think so too. The real test will be, though, the day I will search for
additional info about the tables. And the above text seems neat to me.

From what I understand the patchwork server queues messages based on
the MIME type and contents of the attachment. If that is correct this
should be picked up just fine.

Maybe I can contribute some commentary to the code and ask Suvayu to perhaps
amend the patch to clarify some things (but see my editorial comment at
the end of the email):

<code commentary>
There are two parts to the code: one is in org-exp.el,
org-export-attach-captions-and-attributes(), which matches caption,
label and attr_latex lines and adds text properties for later use by the
export backend. It figures out whether the following item is a table or
a link and it adds the appropriate text property (or properties - one or
more can be present for a given itme) to the item: either the whole
table[fn:1] or the line containing the link. There are three different
properties corresponding to the #+foo construct: 'org-caption,
'org-labeland and 'org-attributes.

The second part is in the specific backend - latex in this case (I did
not look at the others). There are two cases: tables and links.


The table case is handled by org-export-latex tables. It gets the
caption label and attributes from the corresponding text property. It
then further parses the string it gets from the 'org-attributes property
to figure out:

    - whether this is a longtable (a table spanning multiple pages)
      (syntax: the string "longtable" as a word)
    - whether it's a table or a table* (syntax: the string itself)
    - whether it's a tabular (syntax: the string "tabular" followed by a
      single char - that's to catch the tabular*, tabularx and tabulary
      cases I believe).
    - what the width is (syntax: "width=XXX" where XXX is a sequence of
      anything but white space and there is a word boundary before
      "width" - i.e. " width=foo" will set the width to foo but "
      linewidth=foo" will not).
    - what the alignment is (syntax: same as width but with "align"
      instead)
    - what the placement is (syntax: "placement=XXX" - where XXX is a
      string of one or more non-white-space characters.

Suvayu's method works by taking advantage of the fact that the placement
"value" (i.e. the string to the right of the equal sign) does not
contain white space and copies the whole thing as the placement value in
the correct place in the table environment. LaTeX then parses this and
breaks it up into placement and \scriptsize constructs. Since org adds
the placement info to the table environment, \scriptsize sneaks in by
the back door, so to speak.

In the case of a link (which presumably points to an image and handled by
org-export-latex-links and org-export-latex-format-image), the parsing
of the property figures out

   - whether to use wrapfigure (syntax: "wrap" as a word)
   - whether to use the figure env (syntax: "float" as a word)
   - whether to use the figure* env (syntax: "multicolumn" as a word)
   - what the placement is (syntax: same as above)

In addition, whether there is a caption or a label determines whether
the figure is floated or inlined.

</code commentary>

<soapbox> I've tried to keep a neutral tone in (most of) the rest of the
mail, but I have to say that I think clever hacks like this are too
clever for their own good - they are at best an accident of
implementation. The fact that the trick uses the placement option in
order to change the font testifies to that. They should certainly be
documented as hacks on Worg, but I'm not sure they should be documented
in the manual. Of course, it may happen that a really good hack (by some
definition of "really good") should be elevated to a standard and
documented in the manual, but IMO this one does not qualify.  </soapbox>

Comments, corrections, additions are more than welcome.

Nick

Footnotes:

[fn:1] BTW, the documentation of the function says that the property is
added to the first line of the table, but unless I misread the code,
that's wrong: it gets added to the whole table.

Hi Nick,

A very big thank you for that crystal clear code commentary.

After the very clear description above, I agree 100%. I will remove my
addition to the manual and instead try to improve the #+ATTR_LaTeX:
documentation based on your code commentary. At the moment I am facing a
very important deadline for the 8th of June, I will submit a revised
patch after that.

I have attached a patch removing the hack from the manual and making
some other small improvements to the latex export of images. However I
did leave in one sentence regarding the placement option which alludes
that a hack is possible.

Please let me know if this is an improvement.

I made an account with repo.or.cz. I will soon push the changes
documenting the hack on Worg.

The question here is: what does "compatible" mean? Compatible with what?
Now that you added the hack to Worg, it might be better to say: 

"One can also take advantage of this option to pass other, unrelated options
into the figure or table environment (see
[[http://orgmode.org/worg/org-hacks.html#sec-1_6_1][here]] for an example.)"

or something like that.

Thanks for the comment.

I modified the patch as per your suggestion. For the link however,
instead of a direct link to the section I linked to the org hacks page
and named the section, just in case the section ordering changes in
the future for some reason.

Here is my submission:
<http://thread.gmane.org/gmane.emacs.orgmode/42776>

Nick's got a good editorial eye: "compatible options" is probably not
correct.  In the example on Worg hacks, \footnotesize is not an optional
argument to the \table environment, it is a LaTeX command whose scope is
determined by the \table environment within which it is issued.  So,
instead of "One can also pass other compatible options" it would be good
to say "One can also pass LaTeX commands into the \table environment" or
something along those lines.

The entry in Worg hacks looks good to me.  Thanks for taking care of
this, Suvayu.

Many thanks to Nick and Suvayu for figuring out how to get inside the
table environment from Org-mode.  I can't remember how many times I
tried and failed to figure this out on my own ...

All the best,
Tom

Now that the Worg entry exists, I'd like to expand it a bit to add
essentially what Tom mentions in his first paragraph and also to add a
pointer to the "other" solution of this problem.

Suvauy, is that OK with you? Or would you rather I created a
separate hack?

I have modified the Worg entry like this

*** Specifying LaTeX commands to floating environments

The keyword ~placement~ can be used to specify placement options to
floating environments (like =\begin{figure}= and =\begin{table}=}) in
LaTeX export. Org passes along everything passed in options as long as
there are no spaces. One can take advantage of this to pass other
LaTeX commands limited within the scope of the floating environment.

For example one can set the fontsize of a table different from the
rest of the document by putting something like =\footnotesize= right
after the placement options. During LaTeX export using the
~#+ATTR_LaTeX:~ line below:

#+begin_src org
  ,#+ATTR_LaTeX: placement=[<options>]\footnotesize
#+end_src

exports the associated floating environment as shown in the following
block.

#+begin_src latex
\begin{table}[<options>]\footnotesize
...
\end{table}
#+end_src

If both of you agree and there is no important detail or subtlety
missing, I will commit this to Worg.

I'd rewrite this last line slightly - the scope belongs to the command and
the environment withing which the command is placed, limits the scope of the
command:

"...LaTeX commands and have their scope limited to the floating environment."

> For example one can set the fontsize of a table different from the

This is not quite right: the fontsize in the table is by default set to
normal size, but the rest of the document does not have to be normal
size. I suggest

"...For example one can set the fontsize of a table different from the
default normal size by putting something like =\footnotesize= right..."

But common courtesy dictates that I should at least ask :-) In any case,

The best debugging technique I can suggest here is to export to LaTeX
and then look at the .tex file. It's usually clear what broke, who is
responsible and, often, how to fix it.

In this case, the org table looked untouched by the exporter, but when I
got rid of the ``\scriptsize {'', the table was properly exported.

python sessions

[Gary Oberbrunner]

[-- Attachment #1: Type: text/plain, Size: 762 bytes --]

I must be failing to understand something.  I'm running Emacs 24.3 on
Windows, with latest trunk org-mode.  I can't get python functions to
persist across blocks in session mode.  Here's my foo.org:

===============

* My Document
#+BEGIN_SRC python :exports results :results output :session
def foo(x):
  return x+1
print "hi"
#+END_SRC

#+RESULTS:
: hi

#+BEGIN_SRC python :exports results :results output :session
print foo(100)
print "bye"
#+END_SRC

========================

In session mode, shouldn't foo be defined in the second python block?  When
I export this, I get "NameError: name 'foo' is not defined"

I may be doing something wrong, because if I name my python session, I
never see a buffer of that name, and I expected to.  Any help?

You should probably post your babel configuration from .emacs. This
works for me (mostly). I'm using python 3.3 and so the print function
has changed to requiring parentheses. I can switch to a buffer called
*Python*, however, and =print("hi")= works fine.

If I change to =print(foo(100))=, I get 101 in the #+RESULTS block.

It's probably got something to do with your setup; taking a look at
your config should help others help you out.

John

I don't - I get the same error as Gary.

And looking at the code of org-babel-python-initiate-session-by-key,
I don't understand how it's supposed to work: python-buffer is nil
to begin with; the cond takes the first branch and starts a python session.
When we come to

      (setq org-babel-python-buffers
	    (cons (cons session python-buffer)
		  (assq-delete-all session org-babel-python-buffers)))

python-buffer is still nil, so we are cooked.

Maybe python-buffer was set as a side-effect of run-python in earlier
versions of emacs? If so, it does not seem to be the case now.

AFAIU :session is broken, because Python shell as opened by run-python or py-shell isn't used by ob-babel.
Seems ob-babel sends it's code w/ an own shell command, thus opening a new python shell internally every time.

Did :session ever work? Then I might be wrong with this comment.

Not only did it work, it currently works for me. I seem to remember
bad interaction with python modes other than the one shipped with
emacs. In my .emacs I have

;; Python
;; there are several modes. Currently using
https://github.com/fgallina/python.el
;; hopefully oneday a glorious default python mode will be shipped
with emacs and we won't need this anymore.

;; (add-to-list 'load-path "~/.emacs.d/izahn")
;; (require 'python)

;; (setq
;;  python-shell-interpreter "ipython"
;;  python-shell-interpreter-args ""
;;  python-shell-prompt-regexp "In \\[[0-9]+\\]: "
;;  python-shell-prompt-output-regexp "Out\\[[0-9]+\\]: "
;;  python-shell-completion-setup-code
;;    "from IPython.core.completerlib import module_completion"
;;  python-shell-completion-module-string-code
;;    "';'.join(module_completion('''%s'''))\n"
;;  python-shell-completion-string-code
;;    "';'.join(get_ipython().Completer.all_completions('''%s'''))\n")

;; (require 'python-mode) ;;

;; python auto completion
(require 'ac-python)

All the python-mode and ipython mode stuff is commented out partly
because it did not play nice with org-mode. Using the default python
mode works for me. So, for those of you who are finding that this is
not working, what python mode are you using?

emacs-trunk-r112044-20130314-w32-i386.zip, which says it is GNU Emacs
24.3.50.1 (i386-mingw-nt6.1.7601) of 2013-03-14 on VBOX
on Windows 7/64.

My python-mode comes from the python.el shipped with the above emacs, which
says it is Version: 0.24.2.

Org-mode is from git trunk:

That's good news, so it might be fixed soon.

Shipping should not affect the code ;)
Well, if you feel disturbed by python-mode.el,
please file a bug-report at

https://bugs.launchpad.net/python-mode

python-mode.el prepares some keys and fontifying differently
but should not touch python.el commands.

In case it does, probably should change that...

True, which is why I clarified my version. The foo() command still
worked for me; I simply had issues due to print() syntax changes
between 2 -> 3. So... I've tried to eliminate this and retried today
with the following process (note setting the python command to
"python2"):

- Start emacs with `emacs -q`

- M-x load-file ~/Desktop/minimal-config

#+begin_src minimal-config

;; load path
(add-to-list 'load-path "~/.elisp/org.git/lisp/")

;; setup babel languages
(org-babel-do-load-languages
 'org-babel-load-languages
 '((python .t )))
(setq org-babel-python-command "python2")

#+end_src

- For reference
$ python2 --version
Python 2.7.3

On first I get a syntax error executing the first block:

#+RESULTS:
: first
: ... ... ...   File "<stdin>", line 4
:     print "end first"
:         ^
: SyntaxError: invalid syntax

On a whim, I simply inserted a newline, and it worked. Here is the
full file with my executed results (C-c C-c on each block):

#+begin_src orgmode file

* My Document

The first block says:
#+BEGIN_SRC python :exports results :results output :session *PyFoo*
print "first"
def foo(x):
  print "In foo(%s)"%x
  return x+1

print "end first"
#+END_SRC

#+RESULTS:
: first
: ... ... ... >>> end first

The result is:
#+BEGIN_SRC python :exports results :results output :session *PyFoo*
print "hello"
print foo(100)
print "bye"
#+END_SRC

#+RESULTS:
: hello
: In foo(100)
: 101
: bye

#+end_src orgmode file

*Note:* I do not get a *PyFoo* session, only a *Python* buffer. When I
got to kill emacs, here is the session info asking me if I want to
kill the running buffer process:

Python		run	*Python*	/dev/pts/2   python2 -i -c import sys; sys.path.remove('')


So, seems to work for me. This is on Arch Linux:

- uname -a
Linux hostname 3.8.3-2-ARCH #1 SMP PREEMPT Sun Mar 17 13:04:22 CET
2013 x86_64 GNU/Linux

Just caught this... I used -q accidentally instead of -Q. Re-did with
-Q and get same results (successful block execution).

That's pretty close to what I'm using. Can you do me a favor: start
emacs -Q and evaluate the variable org-babel-python-buffers before and
after executing a python block with a :session argument and post
the results?

After starting emacs -Q and loading my minimal setup (including require

 ((:default))
After loading the .org file and doing nothing else, it's the same.
After evaling one code block:
 ((*PyFoo*) (:default))

But note that there is no buffer named *PyFoo* (there is one named
*Python*).

Hi,

started from Emacs -Q checking the example given.

Seems `org-babel-execute':python doesn't get the session flag.

Sure it does:           ^^^^^^^^^^

What it does with it is another matter however. Am I missing something?

I was thinking the concern was over not having the session named
properly, but might be wrong (Andreas could confirm).

I've not used python prior to this, but I use R almost daily in Org
and if I do #+begin_src R :session R, I get a buffer actually named
=R=. In this case, I expected the buffer name would be *PyFoo*.
Checking if it was an issue with asterisks, I used =:session py= and
still just get the default *Python* buffer created.

I guessed Andreas tried with an unnamed session (but I agree it would be
best if he confirms): afaics, if I use a session name, it's passed
correctly in the params argument of org-babel-execute:python as
(:session . "foo"), but in the later processing,
org-babel-python-buffers is not set correctly.

Yes, I think it's ob-python's problem: but as I said before, I don't
understand why it works for you (and Ista Zahn).

I guess it depends on the definition of "works". I don't get python
buffers with the name of the :session variable. But I do get separate
python buffers (.e.g., *Python*, *Python*<2>) for each session, and
python blocks get executed in the right python process. To me that
equals "works", but if the issue is that the buffers don't get named
with the value of :session then no, that doesn't work for me either.

For me, it does not work at all: I don't get python buffers, period
(forget about what they are named :-) )

Reads as it works only with named sessions, but fails with unnamed

It fails to name the python process buffers. Everything else works as
expected. Consider this example:

8<---------cut here------------8<
#+BEGIN_SRC python :exports results :results output :session *foo*
  def foo(x):
    return(x+1)

#+END_SRC

#+RESULTS:


#+BEGIN_SRC python :exports results :results output :session *bar*
  def bar(x):
    return(x+2)

#+END_SRC

#+RESULTS:

#+BEGIN_SRC python :exports results :results output :session *foo*
  print(foo(100))
  print(bar(100))

#+END_SRC

#+RESULTS:
: 101
: Traceback (most recent call last):
:   File "<stdin>", line 1, in <module>
: NameError: name 'bar' is not defined

#+BEGIN_SRC python :exports results :results output :session *bar*
  print(foo(100))
  print(bar(100))

#+END_SRC

#+RESULTS:
: Traceback (most recent call last):
:   File "<stdin>", line 1, in <module>
: NameError: name 'foo' is not defined
: 102

8<---------cut here------------8<

the foo function exists when I use :session foo (and not with :session
bar), and the bar function exists when I uses :session bar (and not
with :session foo). That equals "works" in my book. The only thing
that doesn't "work" is that I have buffers

. * tmp.org               1657  Org		  ~/Desktop/tmp.org
  * *Python*<2>            332  Inferior Python:
  * *Python*               332  Inferior Python:

instead of

May you try still an unnamed session as sent by OP?

Unnamed sessions works as expected:


#+BEGIN_SRC python :exports results :results output :session
  def foo(x):
    return(x+1)

#+END_SRC

#+RESULTS:


#+BEGIN_SRC python :exports results :results output :session
  def bar(x):
    return(x+2)

#+END_SRC

#+RESULTS:

#+BEGIN_SRC python :exports results :results output :session
  print(foo(100))
  print(bar(100))

#+END_SRC

#+RESULTS:
: 101
: 102

At least for unnamed session it's set to nil here

later on it takes the wrong route:

(defun org-babel-python-evaluate

I've attached a patch which works for me, at least in simple tests.  It
should set the buffer name more correctly in session mode.  I also added a
new defcustom for the python command to use for session mode specifically;
that is required for Windows, and I don't think it hurts on other OSes.

Is this fixing *everything* for you, or just the named sessions? Just
wondering if your original issue is fixed, or if you're still having
issues.

If it was fixed... what was it (out of curiosity)? Sorry... still
haven't rebooted into Windows to see if I can replicate on Windows as
well.

Both of the issues in my patch were part of it.  The buffer naming and
using "python -i" in session mode.

And I'm still not sure default (nameless) sessions are working, and also in
my real testcase it still hangs sometimes.  So no, not everything is fine
yet.

I also haven't been following this thread.

Forgetting a patch for the moment, is it possible to conclusively state
that there is or isn't a bug in the current ob-python handling and
naming of sessions?  If there is, is there a recipe for reproducing this
bug?

From participating in evaluating code throughout the discussion and
catching the comments throughout, I'd say yes, at least in terms of
how other babel languages function. In other words =#+begin_src R
:session foo= creates an R session named "foo" whereas doing the same
with =python= instead of =R= does not yield a named session.

From what others experienced, however, the functionality was working
correctly (results were persistent across blocks and two differently
names blocks created two different sessions), just not named
correctly.

See the cond form starting at line 169 in ob-python.el.  Different
session functionality is used based on the `org-babel-python-mode'
variable, and on the version of Emacs in use (prior to 24.1 or not).

The branch taken when `org-babel-python-mode' equals 'python is
certainly broken, as it never saves the name of the newly created
buffer, so session re-use and use of multiple named sessions probably
works only when `org-babel-python-mode' equals 'python-mode.

It looks to have been years since any serious changes were made to this
portion of the code, so if the python-mode(s) have been changing in the
background this sort of bit-rot is not unexpected.

I never use python personally, so while I may be able to fix this at
some point it certainly will not be in the near future (I need to focus
on graduate school in the near term).  It would be great if someone who
uses Python code blocks could step forward to help with maintenance of
ob-python.el.

Sorry I can't be of more help.

That's me: org-babel-python-mode's value is python, so it's no wonder
it's broken given what Eric says. I'm on emacs 24.3.50 where there is
python.el but no python-mode.el. I tried the "cheap" workaround of
switching the value to python-mode, but that does a (require
'python-mode) somewhere, so that option is out as well.

I'm on Emacs 24.3.1 and have no python-mode.el, either (only
python.el). My setup is working correctly (again, with the caveat of
not having named sessions).

The python-mode(s) question should not be at stake, as in context it matters only for the choice,
which command should start the Python shell - run-python or py-shell.

All ob-python needs is a known buffer, commonly "*Python*", connected to a python-process. This seems done by both modes,
so don't expect the bug here.

It sounds like we have the same setup, and the following un-named
session example does not work for me.  The first code block evaluates
successfully, but it doesn't appear to be having any impact on the
default session (e.g., in the *Python* buffer).

    Returns the value of x as expected.

    #+begin_src python :session
      x = 1
      return x
    #+end_src

    #+RESULTS:
    : 1

    #+begin_src python :session
      return x
    #+end_src

    #+RESULTS:

The second code block /should/ have access to the x variable defined
previous, but instead it throws an error because x is undefined.

Currently I'd say session support for python is completely broken.

Have *any* changes been made related to python recently? See my
mailing list post with reproducible example:
- http://www.mail-archive.com/emacs-orgmode@gnu.org/msg68238.html

This was definitely working for me with a minimal config and starting
with `emacs -Q`. I cannot reproduce that example anymore. Sessions
don't work any longer, named or un-named for me, and we had two data
points (myself and Ista) for whom it worked (at least for named).

I think something was changed that broke it for my working setup.
Might be nice to figure out what that was.

Is there a way to see one's local git history? Not the git log, but
something like what git versions I've been hopping from/to with each
successive pull? I could try and see what I was at on 3/20 when I
posted that and when I last pulled? I see a change related to
ob-python from Bastien on 3/19... perhaps I could switch to a commit
prior to that and try again?

I certainly haven't touched this code.  The latest change I see to the
relevant portions of the code is commit 4a0afac6 from Bastien on
Feb. 23rd.

I don't know of a way to show what versions you have used recently.

There are tools to help find the commits causing a change in behavior.
See http://git-scm.com/book/en/Git-Tools-Debugging-with-Git for a pretty
good summary.

At least, we now all agree that it's broken ;-)

I think `git reflog' can do that, but it's kinda cryptic, so it might
be more trouble than it's worth.

As of this morning I've joined the "it does not work" crowd. Python
sessions worked for me last week, but are now completely broken for me
in the way Eric and others describe.

Interesting... checked out back to that commit
(eff59a15d76647ce8282626b9eb463dc3706d56e) and it still doesn't work.
On a whim, I checked my pacman log (Arch's install system) and
coincidentally on Mar 20 /after/ I wrote that post in which things
work, I ran a system package update.

$ grep -i emacs /var/log/pacman.log

[2013-03-20 12:51] upgraded emacs (24.2-4 -> 24.3-1)

Using the Arch Rollback Machine, I downloaded Emacs 24.2.4 and
downgraded (also required downgrading imageMagick from 6.8.3.10 ->
6.8.2.3). Now it works again (refer to the reproducible example from
the mailing list post):
- http://www.mail-archive.com/emacs-orgmode@gnu.org/msg68238.html

Eric, your example fails for me. I get:

>>> x = 1
>>> return x
  File "<stdin>", line 1
SyntaxError: 'return' outside function

This works, hoever:

#+begin_src python :session
      x = 1
      x
#+end_src

#+RESULTS:
: 1

#+begin_src python :session
      x
#+end_src

#+RESULTS:
: 1

So, with emacs 24.2.4 and current Org-mode (pulled just now) and clean
make, *both* named and un-named sessions work for me on Arch Linux.

Yes, because my example only works in external (non session) execution
with the current buggy code, where as your example works with session

Aha! Thanks for sleuthing this out.  So the problem lies in changes to
the python.el distributed with Emacs.  I don't suppose we can ask
whoever made these changes to python.el to fix the breakage they've
caused in Org-mode?

Please give me some time still to investigate. Still doubt it's python.el
But if yes, probably will be able to tell more.

Possibly, but know that for me it works with one Emacs version and not
another, both using the same git version of Org and same minimal
config/setup/test file. Perhaps those affected here should post their
Emacs versions?

Hi,

Ista proved it works for him.

This opens up a compose window in gmail for me. I think this is the
thread you might have wanted to point to:
- http://www.mail-archive.com/emacs-orgmode@gnu.org/msg68267.html

That only speaks to =:session name= argument <=> resultant python buffer names.

As Andreas pointed out, however, there *are* individuals having issues
with the actual code execution, and persistence across blocks with the
same :session names. That's another mystery I don't think we've
solved.

Ista and myself both get proper functionality, but session name
arguments don't create named buffers. Others are not getting proper
functionality.

Right - for my part, the python buffers are not even created, let alone
named correctly; i.e. sessions (named or unnamed) don't work at all.

Whether that's my setup or bugs in ob-python.el, I have no idea at this
point: I haven't had time to investigate.

My guess is that you have a mixed install.  You are mostly running the
Org-mode which ships with Emacs (in which `org-babel-result-cond' is not
defined), but you are running the version of ob-python.el from the
master branch (which expects `org-babel-result-cond' to be defined).

This is an increasingly common problem.  Maybe the following can help.

Hmm, don't see there anything to change wrt to the issue.

Have in my init

(defun ar-load-feature-org-mode ()
   (interactive)
   (add-to-list 'load-path "MY_PATH/feature-org-mode")
   (add-to-list 'load-path "MY_PATH/feature-org-mode/lisp")

   (org-babel-do-load-languages
    'org-babel-load-languages
    '(

      (python . t))))

Maybe should unload existing org-mode first.
Checking for existing features yields:

The key is timing, i.e., the path to the *newest* version of Org-mode
must be at the front of the load-path before the first time Org-mode is
required.  I believe this link is the one I should have sent in my
previous email http://orgmode.org/manual/Installation.html.

Especially important is that

  (add-to-list 'load-path "~/path/to/orgdir/lisp")

is at the top of your .emacs.

> Have in my init

I don't see where you (require 'org) below, but unless it is always done
interactively and always done after calling your load-feature function,
you're probably out of luck.

It is not about "unloading", rather the goal is to *only* load the
newest Org-mode.

Re: python sessions

[-- Attachment #1: Type: text/plain, Size: 1099 bytes --]

I did some further testing.  With my patch, my real org-mode python file is
now actually working.  There were a few gotchas I didn't understand about
session mode and python and matplotlib:

1. In session mode, you are essentially running an interactive python.
 (This is made explicit by my patch, which passes -i).
2. In interactive mode, blank lines are special: they indicate the end of
an indented block.  So you have to write your org-mode python a little
differently when using session mode.
3. matplotlib uses an "interactive" backend when started from an
interactive python (sensibly).  So you have to set the backend explicitly
when using session mode, or it hangs forever with no indication what's
wrong.
4. ob-python does not handle python errors at all in session mode: it
ignores them silently.  This makes it really hard to debug the python code.

I'd like to document #s 1-3; where should that go?
I'd like to work on a patch for #4; it seems like the only thing is to
search in the session buffer for likely error strings.  Is there any better
method anyone can think of?

You should probably create ob-doc-python:
- http://orgmode.org/tmp/worg/org-contrib/babel/languages.html

If you haven't contributed before:
- http://orgmode.org/worg/worg-git.html

Once you clone (after submitting ssh key) with =git clone
worg@orgmode.org:worg.git=, you'd create:

~/path/to/worg.git/org-contrib/babel/languages/ob-doc-python.org

There's a template at:

~/path/to/worg.git/org-contrib/babel/languages/ob-doc-template.org

Thanks for doing this! I can't believe there's no existing page for
Python on Worg. Maybe you can document more than just this, too :)

AFAIU the error string is missing, because it's sent the wrong path-to-interpreter,
i.e. using shell-command.
Shell returns 0 or 1, not the Python errors.

Also the interactive spec is related. Usually Python shell as started from py-shell or run-python include this already.
When send from a python-mode, also the empty lines you mentioned and related stuff is treated.

30min. I finally gave up with Ctrl + g. Out of curiosity, I copied my babel
block code (four simple lines in the form of `var <- read.csv("./file.csv",
header = T, sep = ",")` into the ESS session already started by my first
block execution, and it finished in less than 10 seconds.

Something seems seriously wrong with however org + babel is executing. I'm
suspicious of it printing the output to the minibuffer. I have about 200^2
- 400^2 lines in the csv files. Was shocked that I'd been waiting for org
this whole time and could have just run the code in the ESS R session
directly in a minuscule fraction of the time.

I could post a reproducible csv file if others would like to try this?

I tried the following to make sure it wasn't my setup:

1) from terminal: `emacs -Q --load=~/Desktop/basic-config`, where
basic-config contains:

;; set load paths
;; set load dirs and global config options
(add-to-list 'load-path "~/.elisp/site-lisp/")
(add-to-list 'load-path "~/.elisp/org.git/contrib/lisp/")
(add-to-list 'load-path "~/.elisp/org.git/lisp/")
(add-to-list 'load-path "~/.elisp/site-lisp/ess/lisp/")

;; setup org
(require 'org-install)

;; setup babel languages
(require 'ess-site)
(org-babel-do-load-languages
 'org-babel-load-languages
 '((R . t)))

2) Created a simple org file:

----------
* headline

#+begin_src R :session r :results silent
data <-
read.csv("/media/vault/misc/benefit-plan-analysis/2012/contour_table.csv")
#+end_src
----------

3) Run =C-c C-c YES RET= on block

4) Change to R session and enter the same line manually.

The results are unbelievably different. I didn't let the org session finish
as once it took longer than 30sec I figured I'd get the same results as
with my actual file in this example. Changing to the R session and it was
done in less than 5sec with a ~70mb csv.

Any suggestions on troubleshooting this?


Best regards,
John

You need an ECM. 

I cannot reproduce your issue.

This runs in the same amount of time, whether I execute the src block or
run the code from ESS:


#+begin_src R :session 
write.csv(diag(10)[rep(1:10,100000),],file="abc.csv")
#+end_src

#+begin_src R :session :results output
  system.time(read.csv("abc.csv"))
#+end_src


abc.csv is >25MB

If the behavior you describe only happens with some files, I suggest you
try to bisect them to find the issue.

HTH,

Chuck

I did my best to provide one, other than the file, which I offered to
provide if others requested that I upload it somewhere. Since you have done
so, so have I:
- https://docs.google.com/open?id=0BzQupOSnvw08WHdabHh5VVczRGM

Let me know if that doesn't work. I put it on Google docs and sometimes
have issues with the sharing settings...

You will find the rest needed for a complete ECM of my setup in the
original email:
- minimal config I used with `emacs -Q --load=file`
- org file with minimal babel R block

Let me know if you can reproduce with the linked file. I'm open to
suggestions on how to bisect a file, though it's a column of strings and
several columns of numbers, I'm not exactly sure what to look for.


Best regards,
John

Not an ECM in my book, but ...

On my 4 year old MacBook:

,----
| 
| #+PROPERTY: session *R*
| 
| #+name: bigcsv
| #+begin_src R 
| bigcsv <- Sys.glob("~/Downloads/*.csv")
| #+end_src
| 
| #+RESULTS: bigcsv

|

| 
| #+RESULTS: readbig
| :    user  system elapsed 
| :   5.679   0.306   6.002

`----

About the same as running from ESS.

What else would you like? I provided:
- the config
- the data
- how to [attempt to] reproduce
- the org-mode text

Not sure what to say. Looking for ways to troubleshoot or confirm. Since
you can't confirm, any suggestions on where I should look for my issue? I
can't explain it! All I know is that org chugs and chugs and the direct
execution in ESS session is lightning fast.

Re: Bug? R: Org babel block execution *drastically* slower than in ESS session directly

[Thomas S. Dye]

Hi John,

Have you tried wrapping your R read in system.time()?  If you are right
about :results silent eating up lots of time, then this should fix the
problem.  system.time yields just a bit of output, so shouldn't slow
things down if writing out the data is indeed the problem as you
suspect. 

hth,
Tom

I missed this in the thread so I thought I'd add one more thing to try:

o run iostat (or equivalent) to check how your disks are doing.
  on linux, iostat is part of a package usually called sysstat.

Smaller set of data I'd guess :-) But it does not seem to be the
size of the data that matters.

A few things to try in no particular order:

o run top (or whatever equivalent is available on your OS) and see
  whether the CPU (or one of the CPUs) gets pegged at 100% utilization
  and stays there. If yes, that's an indication of an infinite loop
  somewhere.

o run vmstat (or equivalent) and see if any of the counters are out of whack.
  That requires some experience though.

o use elp-instrument-package to instrument org and run the test, getting
  a profile. I'm not sure whether the results will be useful, since you
  are going to interrupt the test when you run out of patience, but it
  cannot hurt and it might tell you something useful.

o run your ECM on a different computer/OS/emacs installation. Being able
  to compare things side by side is often very useful.

o Halve your file and run the test on each half (but that's probably not
  the problem given Chuck's results).

o Reinstall org from scratch - you might have some corruption in one of
  the compiled files that's causing it to go into an infinite loop.

o Turn on debug-on-quit, start your test, wait a bit and then interrupt
  it. Check the backtrace.  Do it again and check whether the backtrace
  looks the same. That's often an indication of an infinite loop
  (inferring an infinite loop from a two element sample is statistically
  suspect of course, but surprisingly effective nevertheless). The point
  here is that the infinite loop is in emacs and the backtrace tells you
  something about the parties involved.

These are obviously not independent and the results of one experiment will
have to guide you in what you try next.

Good luck,
Nick

This was extremely helpful. Thanks for the suggestions.

Here's my attempt at an ECM, though I'm going to keep using the big file
since that's what's actually doing it an I've already uploaded it :)
- Using emacs config here: http://pastebin.com/raw.php?i=iTbRtCE9
- Using this org-mode file:

#+begin_src org

* headline

#+begin_src R :session r :results silent
# file here:
https://docs.google.com/uc?export=download&confirm=no_antivirus&id=0BzQupOSnvw08WHdabHh5VVczRGM
data <- read.csv("path/to/file.csv")
#+end_src

#+end_src org

- Execute block with C-c C-c after downloading and changing path

- quit any other instances of emacs/R
- start `top` in terminal
- execute block
- Use '<' '>' to sort back and forth between cpu and ram

Observations
- R is at 80-100% cpu for about 5sec
- Then emacs shifts to fairly constant ~100% cpu usage
- After about a minute, the minibuffer expands to ~1/3 of the window height
and fills with the csv data
- Finished after ~5min total time
- So, R took about 5sec, emacs took another 5min to finish

I'll skip for now; no experience with that.

Results:
- Didn't even see R flash on the screen this time; emacs just jumped to 100%
- After 1min 10sec, the minibuffer filled with data
- At that point I quit, as I think it will be a repeat of the above

Don't have experience with debugging. It brings me to a *Backtrace* buffer,
which is empty except for the line "Debugger entered--Lisp error: (quit)"

Thanks for the suggestions and help. That was quite above and beyond. Much
appreciated.

So not an infinite loop. That's progress ;-)

Perhaps emacs is thrashing? If you are on linux, use swapon -s
or (perhaps better) iostat, or (perhaps even better, at least if
you are on the Gnome 2.x desktop[fn:1]), run the system monitor
applet, click Properties, enable all the monitored resources
(cpu, mem, net, swap, load, disk) and watch it while you are
running the test: in particular, check memory and swap. If you
are swapping even a little bit, that's enough to cause severe
performacne problems[fn:2], which can be cured by using less memory
(so stop any memory hogs from running) or by adding memory.

Top can also show you memory and swap so maybe that's the quickest
way to check.

Nick

Footnotes:

[fn:1] You can pobably do this in other desktops but I have no
       experience with them, so no guidance to give.

[fn:2] My old laptop with 1GB of memory would swap whenever I ran mairix
       to index my mail: it would take 30 minutes or so to finish.  My
       new(er) laptop has 4GB and finishes in 30 seconds: memory usage
       peaks at about 2.5 GB.

Oh, and I'm conscious of R using RAM, so I tried to run this stuff without
browsers open, no other R sessions, etc. Prior to running R and without a
browser, I'm typically around 10-15% RAM utilized...

I have 4gb, so that should be enough to read this, especially per Chuck's
results! This is also an i7 work computer. It should fly (and in the ESS
session itself, it does).

Check /var/log/syslog (or thereabouts) to see if the kernel is seeing errors with
some blocks on the disk and keeps retrying. Assuming SMART is enabled, run smartctl -a
as well and look for problems.

Re: Bug? R: Org babel block execution *drastically* slower than in ESS session directly

[Aaron Ecay]

I just ran into this problem.  It is caused by the calls to
‘org-babel-import-elisp-from-file’ on lines 310 and 343 of ‘ob-R.el’
(for non-session and session code blocks respectively).  I determined
this by setting ‘debug-on-quit’ to t in Emacs, then hitting C-g when cpu
usage spiked, and examining the backtrace.

It seems like Emacs tries to read in the last value of the R command, to
print it in the minibuffer.  It gets bogged down doing so.  As a
stopgap, putting NULL as the last line of the source block fixes the
problem (the value “returned” by the block is just NULL).  I believe
setting “:results output” (as opposed to “value”) would also make the
bug disappear, since the output will be very small.  This is likely what
made cberry’s test differ from John’s.

I’m not sure what the right strategy would be for a fix.  Two ideas
would be:
1) adding a sanity check to o-b-import-elisp-from-file, which asks the
   user whether to really import very large files (or just ignores such
   files)
2) adding a new :results handling header arg “really-silent” (probably
   with a better name...) that discards the result entirely, not even
   printing it to the minibuffer.

Yes! I'm not crazy! I'm not very familiar with the debug options in emacs
and had a heck of a time setting it up right the last time. Thanks so much
for checking this out.

Crazy. I really wondered if it had something to do with trying to spit out
the results into the minibuffer. Why is that behavior included?

Are you sure it's only on file import? I was generating some large output
when I first experienced this. It was only to avoid running that code that
I wrote it to file once and decided to just read it once per session
afterward (thinking reading would be faster than generating the input on
demand). I was generating a grid of interactions with something akin to:

#+begin_src R
dat <- expand.grid(var1 = seq(0, 40000, by = 200), var2 = seq(0, 40000, by
= 200))

I can check this tomorrow if you'd like, but I remember it lagging as it
tried to print all of that into the minibuffer.

I like this, in addition to changing the minibuffer output as it is. It
would be fantastic to have the minibuffer say more than it does already
(something akin to "Block execution complete"). I have to change to the R
buffer to see if there were any errors. I like how the LaTeX exporter tells
you if PDF export failed. It'd be nice to see something like (in addition
to no results in the minibuffer), "Block execution complete but with
errors."

Thanks again, and I'm glad you were able to track this down.

“:results silent” just means “silent except for the minibuffer”; IDK
why.

Yes, that’s what I meant (and didn’t explain well).  Org writes R’s
output to a file, and then imports it into Emacs (to print in the
minibuffer).  But it also does an expensive transformation before
printing it – whence the slowdown.

I agree that this is sub-optimal.

I seem to remember that ob-R.el is unmaintained (or was at some point in
the past).  Once there is consensus on what a fix should look like, I
can attempt to produce a patch implementing it.  And I’ll take a crack
at error reporting in the minibuffer too.

I think "silent" has to do with the Org buffer that contains the source
code block.  Non-silent blocks do something in the buffer.  This was,
for me, one of the amazing things about babel when it was being
developed.  One could "speak" any language and have sensible results
written back to a plain text file.

Yes, ob-R.el is currently without a maintainer. My sense and experience
is that Eric S. is happy to entertain patches to the various ob language
files.  My experience is also that active maintainers welcome
patches--I don't think there is a barrier to patch proposals.

I can help with documentation if your patch results in some substantive
changes to R support in babel.  Please don't hesitate to ask if need be.

All the best,
Tom

Yes, the existing ":results silent" option still echos the results to
the minibuffer.  It was originally added in the case where one does not
want to change the Org-mode buffer (but would still like to see code
block output).

The attached patch adds a "really-silent" results header argument.  To
see the impact compare the running time of the following two code
blocks.

    #+begin_src sh :results really-silent
      seq 100000000
    #+end_src

    #+begin_src sh :results silent
      seq 100000000
    #+end_src

Before such a patch is applied it would need corresponding
documentation, and the "really-silent" moniker may need to be
reconsidered in favor of something more informative (the main purpose of
this header argument is not silence but is rather avoiding all post
processing), and ideally shorter as well.  These new header arguments
are of no value if they are not easily discover-able and easily
remember-able to help others avoid the same issue that launched this
thread.

Cheers,

Subject: [PATCH] "really-silent" header avoids result post-process

This patch introduces a new header argument which hide all code block
results from Emacs so that they are not processed into Emacs-lisp
objects; a process which may take a great deal of time for large
objects.

* lisp/ob.el (org-babel-common-header-args-w-values): Adding the new
  "really-silent" header argument.
  (org-babel-execute-src-block): Don't do *any* result processing if the
  "really-silent" header argument has been specified.
  (org-babel-sha1-hash): Remove the really-silent header argument from
  header arg lists when calculating cache sums.
  (org-babel-insert-result): Flesh out some documentation.

this is simply great!  Thank a lot.  I just tested and like it a lot!

With respect to the name: I think choosing a new name is hard because it
really should be "silent".  What is now "silent" would better be named
"minibuffer" or sth. similar.  But since changing that would break quite
some (of my) code, I would suggest simply "none" for the new
"really-silent".

Just my 2ct.

Thanks again.  I'll start using it right now.

Andreas

I like the "none" idea. Or another approach would be a variable/in-buffer
setting that defines the meaning of "silent"? Something like
=org-babel-echo-results-in-minibuffer= or something like that? Though
perhaps folks would like to mix and match silent and none within the same
document.

Thanks for creating the patch, Eric. I'll try shortly.

John

Yes please, especially since I tried ":results none" two days ago to
achieve that effect and wondered why it wouldn't work.  :-)

Great, since "none" seems like the obvious choice I just committed a
version of this patch which places this behavior behind ":results none".

At some point documentation should be added to the relevant portion of
the manual, but at least we now have this for those reading the mailing
list and for those who simply try "none" with this behavior in mind.

Unfortunately, the attached patch doesn’t work correctly.  This can be
seen by replacing the “seq” command in your examples with a command that
has side effects – notify-send, aplay, etc.  In the :results none” case,
the command is not run at all.

That’s because the “(funcall cmd body params)” call at l. 574 of ob.el
(patched version) has been put in a branch that is only run if :results
!= none.  That funcall is responsible for actually evaluating the code
block.

(The indentation of the patch as applied isn’t correct – the two
branches of the if on l. 565 are indented at the same depth as each
other, and as the if.  So it’s possible that the problem is due to a
paren in the wrong place.  But I cannot see a way to make this approach
work.)

The code generating the slowdown is in backend-specific files.  So, for
example, a new branch needs to be added to the case statements in
org-babel-R-evaluate(-session), to detect the :results none case and not
read the result.  I suspect that each backend will need this treatment
(unless some of them share code).

In the meantime, attached to this email is a patch that implements a
size check on reading results.  If the results file is over 10kb, it
asks the user whether to proceed.  You can test this by evaluating:

#+begin_src sh :results silent
  seq 10000
#+end_src

10kb of results actually doesn’t result in a very serious hang (~5sec on
my system).  But I chose the value as more of a sanity check – odds are
(?) that very few people want to see 10k of results in the (mini)buffer.
The value could be made customizable.

I also chose the polarity of the y-or-n-p so that picking the default
(yes) option does the sensible thing of not hanging emacs, although it
thus does discard data.  I’m not sure which is the worse problem.

Yes, sometimes I find this approach to be preferable to make the diffs

I may be outvoted, but I find this approach too be overly complicated.
Also, size may frequently not be the best proxy for the time which Emacs
will take to ingest the results.

Re: Bug? R: Org babel block execution *drastically* slower than in ESS session directly

This is no longer a (complete) fix for the original problem, though.  (A
large part of) the slowdown comes from reading the results from a temp
file and transforming them into an elispy format, which is handled by
the backends.  Your code only prevents them from being echoed to the
minibuffer.

You can see this by trying your original “seq” tests.  You should see
them taking the same (very long) amount of time.

If you set debug-on-quit to t (before evaluating the block) and
interrupt emacs with C-g when it hangs, you’ll see a backtrace that goes
through ‘org-babel-execute:sh’ and then
‘org-babel-import-elisp-from-file’.  The presence of the former in the
call stack is why I claim that per-backend fixes are ultimately needed.
The latter is where my patch addresses the problem in a temporary way.

I agree that my patch is a stopgap.  But until per-backend fixes are
available, this allows certain code to run that otherwise wouldn’t (at
least not without hacks, such as putting NULL at the end of an R source
block so that the “.Last.value” in the block is trivial).

I apologize for rushing through your previous email and missing
important portions of the content.

I'm attaching a new patch which should serve as a more permanent
solution, however, given that it touches almost every backend I want to
give the list a chance to try it out before committing it.  This patch
introduces a new macro (`org-babel-result-cond') which attempts to unify
the results processing.  Not only does this check for ":results none"
and ignore all results in that case, but it also checks whether the
results should be parsed as a scalar or a vector.  Hopefully this will
serve as useful refactoring and reduce the total amount of code as well
as provide for more uniform results processing across languages.

Please let me know if this looks like a good permanent solution.

I see that I'm now getting 5 test failures with this patch applied
locally, but I won't have time to look at this further until early next
week at the earliest, so I'm sharing the existing patch now.

Thanks,

Alright, I've now changed the above patch so that as many tests are
passing locally as were passing without the patch.  Given that, I've
applied this patch to the main git repository.  Everything which worked
previously should still be working, only now the ":results none" options
should have the desired effect.

Alternate format for datetree

[c b]

[-- Attachment #1: Type: text/plain, Size: 876 bytes --]

Hi,

I have been using org-mode for about 18 months now and love it. I recently
came across the org-capture file+datetree format and it is just what I am
looking for, except that I need a slightly different format described as
below

Currently format is

* 2012
** 2012-08
*** 2012-08-26 Sunday
**** [2012-08-26 Sun 13:00] My note for this Sunday afternoon

Needed format is

* 08
** 26
*** 2012 Sunday
**** [2012-08-26 Sun 13:00] My note for this Sunday afternoon

Basically, I need to have the "root" of the date tree on the month,
followed by date and then Year, so that for a particular date, I can see
all yearly activity.

Is there currently a way to alter this?

If not, how would I go about adding a file+monthtree format for org-capture?

Any suggestions would be appreciated

Kindly copy me on the response as I am not subscribed to this mailing list.

Thanks,
c.b.

I was looking for something similar and someone provided a custom
capture template that allowed for using inactive timestamps vs. the
default datetree format.

See the example provided here:
- http://osdir.com/ml/emacs-orgmode-gnu/2012-08/msg00396.html

I fiddled with this a bit, not really being familiar and learned a
good bit in the process to achieve your desired format. Give this a
try:

#+begin_src .emacs
(setq org-capture-templates
`(("t" "test" entry
(file+headline "~/file.org"
,(format "%s"
(format-time-string "%m")))
,(format "** %s \n*** %s-%s \n**** [%s-%s-%s %s %s:%s] "
(format-time-string "%d")
(format-time-string "%Y")
(format-time-string "%A")
(format-time-string "%Y")
(format-time-string "%m")
(format-time-string "%d")
(format-time-string "%a")
(format-time-string "%H")
(format-time-string "%M"))
)))
#+end_src

One thing I couldn't figure out was how to insert a %? after that
second long format option. If I just put in %?, loading .emacs caused
the error "Not enough arguments to format" or something like that. I'm
sure there's some secret elisp escape syntax I just don't know. I
tried various combinations of \ and '("") with no success.

That'd put the finishing touch on things so your cursor was where you wanted it.

Also, for those seeing this... is this how you would accomplish c.b's
goal? I just used the sample provided to me in the earlier mailing
list email to see if I was up for the challenge, but I have no basis
for knowing whether it's a good solution.


Hope that helps!
John

Try

--8<---------------cut here---------------start------------->8---
,(format "** %s \n*** %s-%s \n**** [%s-%s-%s %s %s:%s] %%?"
--8<---------------cut here---------------end--------------->8---

You basically need to escape the % from being interpreted by format.
C-h f format RET says

,----
| ...
| Use %% to put a single % into the output.
| ...
`----

I would like to use something like this. However, using a recent git 
checkout of org mode and the following simple template from the original 
list message:

("u"
          "Test"
          entry
          (file+headline "~/test.org"
                         ,(format "%s %s"
                                  (format-time-string "%B")
                                  (format-time-string "%Y"))))
I get the following error:

Debugger entered--Lisp error: (wrong-type-argument stringp (\, (format 
"%s %s" (format-time-string "%B") (format-time-string "%Y"))))
   regexp-quote((\, (format "%s %s" (format-time-string "%B") 
(format-time-string "%Y"))))
   org-capture-set-target-location()
   org-capture(nil)
   call-interactively(org-capture nil nil)

I also get the same error from John Hendy's template. Is this a bug in 
recent versions of org, or is there an error in the template lisp? I 
have tried doing a git bisect, but can only go back a few commits, as my 
config now includes  several things that have only recently been added 
to org.

You are missing the backquote:

--8<---------------cut here---------------start------------->8---
 `("u"
          "Test"
          entry
          (file+headline "~/test.org"
                         ,(format "%s %s"

Thanks Nick. Hwever with the following minimal template, from the OP, I 
still get the error:

;; org-capture settings.
(setq org-capture-templates
`(("t" "test" entry
(file+headline "~/file.org"
,(format "%s"
(format-time-string "%m")))
,(format "** %s \n*** %s-%s \n**** [%s-%s-%s %s %s:%s] "
(format-time-string "%d")
(format-time-string "%Y")
(format-time-string "%A")
(format-time-string "%Y")
(format-time-string "%m")
(format-time-string "%d")
(format-time-string "%a")
(format-time-string "%H")
(format-time-string "%M"))
)))

I put this in a minimal .emacs and I *do not* get an error. Please try
the appended minimal .emacs (change the pathnames appropriately) with

emacs -q -l /path/to/minimal/.emacs

M-x org-capture RET t
M-x org-capture RET u

and post the backtrace if any. Both of them work fine for me. You are
sure you used a backquote?

Odd. I just copied and pasted this into my .emacs and commented out my
actual capture templates section entirely, leaving only this and it
works as expected.

(Just saw Nick's response as well and was going to both try and
suggest similar with a minimal .emacs).

Thanks both. I'll try with a minimal emacs and post the results. 
However, it may be a day or two as I am currently in the far West of 
Ireland with very variable Internet connections

Now back with a reliable Internet connection. Thanks for the minimal 
example, which worked correctly. In my full setup, I have quite a lot of 
template definitions. It turned out that I had put the backquote the 
wrong side of a bracket.

Hi John and Nick,

Thank a lot for your suggestions. I finally got it working. It took a while
to figure out that the back-tick is different from the quote.
I am an elisp newbie. Is there an easy explanation of why we need a
back-tick vs. quote?

Also, I found that while the template works, it creates a new tree every
time I capture an entry as follows

* 09
** 05
*** 2012 - Wednesday
**** [2012-09-05 Wed 22:31] My first working month tree note

* 09
** 05
*** 2012 - Wednesday
**** [2012-09-05 Wed 22:31] My second month tree note

#1. Is there any way to consolidate this like the following?

* 09
** 05
*** 2012 - Wednesday
**** [2012-09-05 Wed 22:31] My first working month tree note
**** [2012-09-05 Wed 22:3*5*] My first working month tree note

#2 The time always is reported as 22:31 (I guess that's the time I launched
emacs). Is there a way for the time stamp to be corrected based on the
current time? I generally leave emacs running for days together, so the
time it's launched doesn't really work for me.

Once again, thanks a lot for your help!

quote says: take the next expression as is - do not evaluate anything in it.

backquote says: take the next expression as is - do not evaluate
	  anything in it, *except* do evaluate any subexpression
	  preceded by a comma and put the result back into the original
	  expression in place of the comma-ed subexpression.

E.g

'(a b c) -> (a b c)
`(a b c) -> (a b c)  ; because there is no comma

'(a (+ 2 3)) -> (a (+ 2 3))
`(a (+ 2 3)) -> (a (+ 2 3)) ; again no comma
`(a ,(+ 2 3)) -> (a 5)

Incidentally, if you switch to the *scratch* buffer (which is in Lisp
Interaction mode), you can type these expressions in and evaluate each
one by pressing C-j at the end of each expression.

So they both quote: the first one unconditionally, the second mostly but
allowing partial evaluation of subexpressions.

BTW, '(a b c) is shorthand for (quote (a b c)): internally, the lisp
reader translates the first to the second and then the evaluator
evaluates the quote form, returning its (unevaluated) argument: that's
why quote is a "special form" - by contrast, ordinary functions always
evaluate their arguments.

`(a b ,(+ 2 3)) is also shorthand for (backquote (a b ,(+ 2 3))) but the
implementation is necessarily more complicated: backquote is implemented
as a macro (because it is a special form, its argument is not evaluated,
so it cannot be implemented as a function; it has to be implemented as a
macro), but then backquote has to dig into the structure to look for ,
(and also for the somewhat different ,@ construct - see the docs) and do what's
necessary.

Another example is provided by the docstring of backquote itself: C-h f
backquote RET to see it.

For more info, see the elisp manual, chapter 9 on evaluation:

     (info "(elisp) Evaluation")

and two sections therein in particular, 9.3 Quoting, and 9.4 Backquote:

    (info "(elisp) Quoting")
    (info "(elisp) Backquote")

Two useful links in this respect.

    http://www.lisperati.com/syntax.html
    http://www.lisperati.com/looking.html

Just focus on the diagrams in the link - particularly the flip-flop
diagram in the second link.  Once you have the flip-flop image in mind,
you will realize that characters "`" and "," are also rotated 180
degrees and are actually flip-flops.

Now try mapping what flip to "don't evaluate" and flop to "evaluate".

Then you can move on to what Nick says or the doc says.

You might check out a question I asked that's quite similar.
Basically... no, not unless the headline already exists. Then you have
to use file+olp instead of file+headline. Check out my example:
-- http://lists.gnu.org/archive/html/emacs-orgmode/2012-08/msg01465.html

Orgmode can file to a headline passed in the capture template
immediately after the =(... file+headline
"headline-to-file-under-here")=, but the longer =`(format...= tells
Org to insert that text every time. Thus, our sub-headline evaluation
will always create that text anew. The workaround will be for you to
re-arrange the =`(format...= section and put it above. In other words,
this:

----------
(setq org-capture-templates
`(("t" "test" entry
(file+headline "~/file.org"
,(format "%s"
(format-time-string "%m")))
,(format "** %s \n*** %s-%s \n**** [%s-%s-%s %s %s:%s] "
(format-time-string "%d")
(format-time-string "%Y")
(format-time-string "%A")
(format-time-string "%Y")
(format-time-string "%m")
(format-time-string "%d")
(format-time-string "%a")
(format-time-string "%H")
(format-time-string "%M"))
)))
----------

Needs to become something like this:
----------
(setq org-capture-templates
`(("t" "test" entry
(file+olp "~/file.org"
,(format "%s" ;; first headline
(format-time-string "%m")
,(format "%s" ;; second headline
(format-time-string "%d")
,(format "%s - %s"
(format-time-string "%Y")
(format-time-string "%A")))
,(format "**** [%s-%s-%s %s %s:%s] "
(format-time-string "%Y")
(format-time-string "%m")
(format-time-string "%d")
(format-time-string "%a")
(format-time-string "%H")
(format-time-string "%M"))
)))
----------

Something like that (I wrote this in email and didn't check it). That
tells Org to look for a *pre-existing* headline structure in this
form:
----------
* Month (in ## format, like 09 for September)
** Day (in ## format, like 06 for the 6th)
*** Year - Day (in #### - Name format like 2012 - Thursday
----------

And under that, it will file:
----------
**** [timestamp] what you write
----------

But... this means you need to pre-create your daily headline structure.

I think a reasonable feature request would be to have something like a
=:use-existing-capture-headline t= option that would tell Org to
*either* create a new capture headline (as on the first time used that
day) or file into a pre-existing headline if one already exists in
that form. Something like a hybrid between file+headline and file+olp.

Hope that makes sense. I think my example in the link above should help as well.

Did you change the above to 21:35 or did it file like that? Not sure
why H:M wouldn't expand to the current date. One thing that just
occurred to me, however, is to replace that whole timestamp string
with "%%U% and Org will just expand it to a date+time stamp.

Good luck,
John

This is actually an issue with all of the backtick elements in the
capture template but it shows up most obviously in the timestamp
portion.  I only realized this after providing the solution that John
had referenced earlier in this thread.  Backticks are expanded on
evaluation and resolve to the specific value of their called portions.
 So for the headlines you will need to re-evaluate the template every
day to update it (or restart emacs).

For the timestamp itself you should be able to use the %U escape in
the capture template and it will insert the date and time on it's own.

Pass LaTeX exporter option prior to \documentclass

Hi,

I'm creating a beamer presentation and screencasting a walkthrough of
it for work. I wanted to use impress!ve, but was getting errors about
there being no pages in the document. [1] In looking this error up, it
seems that impressive requires pdf version 1.4, which can be passed
with this:

\pdfminorversion=4

Unfortunately, exporting via Orgmode causes this error with that command:

,---
| ! pdfTeX error (setup): \pdfminorversion cannot be changed after data is
| written to the PDF file.
`---

In searching that error, I found the 1.4 documentation, which states:[2]

,---
| it probably means that some package loaded before pdf14 did write
data to the PDF file.
| In case the document class is (indirectly) doing it, you’ll need to
load pdf14 even before the
| \documentclass command, using \RequirePackage{pdf14} as the first
line of your source file.
`---

Using this suggestion solves my problem.

There doesn't seem to be a way to get this as the first line via
Orgmode; I have to export and then go to the .tex file directly to
change it. Any suggestions? I realize this is a pretty fringe case. If
it's one where it's just not worth it to implement something if
nothing already exists, that's completely acceptable to me. I just
thought I'd bring it up! It's primarily a nuisance because impressive
hasn't been updated in about a year. I wouldn't normally use it, but
the ability to zoom, use a "spotlight" for the mouse, and so on are
just really neat for something like this.

Disclaimer: What follows is an extremely hacky untested solution using
some shell foo.

By default org-latex-to-pdf-process is bound to something like this:

pdflatex -interaction nonstopmode -output-directory %o %f

You could try replacing that with the following:

pdflatex -interaction nonstopmode -output-directory %o
\pdfminorversion=4 $(cat %f)

Hope this helps.

I did some testing. The following should work.

pdflatex -interaction nonstopmode -output-directory %o
\\pdfminorversion=4 \\input{%f}

Using tex commands is probably better than shell expansion.

Thanks for the workaround! So, to be clear, I'd type in what you wrote
when I'm prompted for the command to use after =C-c C-e p=?

No. I don't think org prompts for the command when exporting. You
should use customize to set the variable org-latex-to-pdf-process to
the above command.

Ah, sorry. You're right. I was thinking of =C-c C-c= from the .tex file buffer.

Thanks again! It was a fringe scenario for sure!

Alternatively, you can define a new entry in org-export-latex-classes
that does what you want - I just cribbed the existing beamer entry and
modified it a bit (I had called it "beamerpdf14" at first, but apparently
numerics are not allowed):

,----
| (require 'org-latex)
| (setq beamerpdf  '("beamerpdf" "\\pdfminorversion=4\\documentclass{beamer}" org-beamer-sectioning))
| (add-to-list 'org-export-latex-classes beamerpdf t)
`----

and then set

#+LATEX_CLASS: beamerpdf

in your org file.

Prompt for time when clocking in?

[Nathan Neff]

Is there a way to pull up a date/time prompt when clocking in to a task?

Sometimes, I started a task 15 minutes ago, and have to go through the following
steps:

1) clock in on the task,
2) Go to the CLOCK section for that header and press tab to open it
3) Fix the clock-in time

If it's not built in, does anyone have any slick functions that would accomplish
the same thing? :-)

Thanks,

Check out a thread I started a bit back on this exact topic:
--- http://www.mail-archive.com/emacs-orgmode@gnu.org/msg40498.html

It wasn't exactly what I expected, the suggestion by Bernt for `M-x
org-resolve-clocks` works reasonably well if you are trying to clock
back-to-back activities. Post back after you read that perhaps? Maybe
you'll find something helpful.

org-clock-in takes an optional start-time argument which is used instead
of the current time when non-nil. So I tried

(setq ct (current-time))
(setq start-time (cons (car ct) (list (- (cadr ct) 900) (caddr ct))))

and started a clock on a task with

ESC ESC : (org-clock-in nil start-time)

and it got clocked in 15 minutes before the current time.

Now I don't propose this as a good UI :-), but it would require just a
small wrapper for it to dtrt.

HTH,
Nick

Re: Prompt for time when clocking in?

[Nathan Neff]

Some progress --

I used Nick's suggestion combined with the org-read-date function.

This is my first attempt -- It will prompt you for a time, and clock
in to the headline that the cursor is on with that time.

(defun njn/clock-in-at-time()
       (interactive)
(setq start-time (org-read-date 't 't))
(org-clock-in nil start-time)
    )

It's a bit wonky if you clock in to a past time, and then you want to
resolve that clock, but my main use-case for now is this:

1) I start doing something
2) I forgot to clock in
3) I don't want to press 8 keys in order to clock in 15 minutes ago.

This solution should work for now.  Although, I could see it being a
handy way to
prompt for clock-in *and* clock-out times.

Thanks for the suggestions,

--Nate

Two minor nits: t is a constant so you don't need to quote it; emacs-lisp
mode helps with indentation (putting it in a code block - see below -
in an org file and using C-c ' to edit it works wonderfully).

I'm not sure whether 'tis better to specify relative or absolute times
("let's see: I should have clocked in 15 mins ago" vs "Let's see: I
should have clocked in at 12:20"), but just in case you want to try the
alternatives, here are two dummy function functions for the two
alternatives - they just print the result time in the echo area.

The rel time can use a prefix arg (ESC -15 M-x
rel/dummy-clock-in-at-time) or the minibuffer if no prefix arg is
specified (and you might want to bias it towards the past, so 15 = 15
mins ago and -15 = 15 mins from now, but that might be a bit
perverse).

FWIW, I think I would tend to prefer your implementation, but since I
clock nothing, I'm no expert :-)

Nick

#+begin_src elisp

(defun rel/dummy-clock-in-at-time (nmin)
  (interactive "N+/-minutes: ")
  (setq start-time (time-add (current-time) (seconds-to-time (* nmin 60))))
  (message (format-time-string "%H:%M:%S" start-time)))

(defun abs/dummy-clock-in-at-time()
  (interactive)
  (setq start-time (org-read-date t t))
  (message (format-time-string "%H:%M:%S" start-time)))

#+end_src

Thanks for your suggestions re: using Emacs to edit
lisp code and using the t in lieu of 't -- I appreciate these types
of style/coding comments immensely!

Nick, I like the ability to just type "15", but I also like the
ability to use the
familiar org-calendar in case I want to get fancier (for example, I
forgot to clock
something that I worked on yesterday)

It would be a cool feature of org-read-date to be able to type "-15M"
and have org-read-date go back 15 minutes from the current date/time.
I played around with org-read date for something like -"15m" and
"-15M", but the "-15m" went back 15 *months*, not minutes.

Does anyone know if there's a way to specify a relative *time* using
org-read-date?  For example, something like -15M would be "15 minutes
earlier"?

For editing clock times I use the agenda

C-c a a v c

and then visit the lines I want to edit from the agenda with RET.

Handling errors in command line exporting of agenda?

[John Hendy]

I have a custom view that I'm exporting to a text file and then
displaying on my wallpaper with conky. I noticed that if I actually
have emacs open and a file is autosaved but not saved "for real," then
the exported text file is blank. I use this command in cron:

,---
| emacs -batch -l ~/.emacs -eval '(org-batch-agenda "w")' >
~/org/aux/agenda-export.txt
`---

I ran this from the command line after noticing the cron job was
coming up empty, and saw the error:

,---
| ...file.org locked by jwhendy... (pid 27250): (s, q, p, ?)?
`---

If I saved the offending file, it re-ran fine. As soon as enough time
elapsed to generate an auto-save (I'm assuming), it failed again. Any
suggestions on how to proceed? For example, I though of:

1) writing a script that could handle the failure and leave the
current agenda exported text file if it happened
2) a way to respond to the emacs query (not sure what s, p, q, ? do)

Anything else that would work? If it's frozen and "not safe" to run
this command while a file is open/being modified, then just aborting
and leaving the status quot in the text file is what I'd like to do.


Thanks!
John

Do you run into the same problem if you one the file before hand in
read only mode? Something like this before the agenda command might
work.

(find-file-read-only "FILENAME")

How would I do this via the command line? Also, it's pulling from
about 10 project files, so I'm not sure if I'd have to do this for
every file or how that works since the org-batch-agenda command seems
to be pulling from all of them. Perhaps there's some way to trigger
emacs to think, "Everything is read-only from here out"?

If you can use wildcards to specify your files, it might be possible by
just one extra call to --eval. Something like this might work:

emacs --batch -l ~/.emacs --eval '(find-file-read-only "<wildcard>" t)' \
      --eval '(org-batch-agenda "w")' > ~/org/aux/agenda-export.txt

Hmm. That might work. Everything I pull from is in ~/org... could the
wildcard simply be "~/*.org"? Forgive my emacs wildcard ignorance. I
did some filename regexp magic *once* and it took me like two hours to
learn the syntax just to turn camera directory names from 10#_MMDD to
YYYY-MM-DD...

As far as I know, emacs accepts any wildcard that is valid in the shell.
Since all your files are in ~/org, I would say try "~/org/*.org". The
'~/org/' limits it to files within your org directory and the '*.org'[1]
limits it to all files with a .org extension.

I hope this helps. :)

Footnotes:

[1] The asterisk (*) stands for zero or more characters. You can find
    more details in `man bash` under the heading "Pattern Matching".

Bummer, this is not working:

,---
| emacs -batch -l ~/.emacs -eval '(find-file-read-only "~/org/*.org" t)' \
| -eval '(org-batch-agenda "e")' > ~/org/aux/agenda-export.txt
`---

Do you see anything wrong with that? I guess I wonder what that first
part will do as perhaps the org-batch-agenda command is not
necessarily going to follow suit with the read-only command. As in,
does the first eval command affect anything that the org-batch-agenda
command is going to do? Is it trying to do the equivalent of opening
up all *.org files in read-only buffers and then run the agenda
export?

Your problem is the long options are wrong. According to the manpages,
there should be 2 hyphens.

--eval and --batch.

Well, that might be *a* problem, but it's not *the* problem.

This produces the same results:
,---
| emacs --batch -l ~/.emacs --eval '(find-file-read-only "~/org/*.org" t)' \
| --eval '(org-batch-agenda "e")' > ~/org/aux/agenda-export.txt
`---

I get this from the command line:
,---
| ...~/org/rigor.org locked by jwhendy... (pid 10935): (s, q, p, ?)?
`---

Which means that when executed from cron, it won't proceed.

Also, good to know re. the man pages... however Worg is wrong, then.
Directly from Worg [1]:

| | emacs -batch -l ~/.emacs -eval '(org-batch-agenda "e")'
| `---
|
| or
|
| ,---
| |emacs -batch -l ~/.emacs -eval '(org-publish-all)'
| `---
`----------

The manual contains the same syntax. [2]

Nope - emacs recognizes both (presumably the single hyphen ones are deprecated
but they still work:

    emacs -batch -eval '(message "foo")'

works fine.

Not true - if you want wildcards expanded, you have to do it yourself.
E.g. C-h f file-expand-wildcards

Thanks. I tried with this based on this new information:

,---
|  emacs --batch -l ~/.emacs --eval '(find-file-read-only \
| (file-expand-wildcards "~/org/*.org") t)' \
| --eval '(org-batch-agenda "e")' > ~/org/aux/agenda-export.txt
`---

But I get this error:
,---
| Wrong type argument: stringp, ("~/org/file1.org" "~/org/file2.org"... etc.)
`---

I'm assuming something about how I used this is returning the wrong data type?

As another option, if I run this and just respond with "p" when I'm
asked about the lock (proceed), it works. I'm assuming that running
agenda won't mess up an unsaved file, but that it just accesses it for
todos and other information. If this is the case and an automatic
"proceed" is safe... is there a way to pass some sort of "--force"
option to emacs from the command line to override the lock when it's
encountered?

I'm running through cron and thus am not able to manually respond to the prompt.


Thanks,
John

Yes:

| This returns a list of file names which match the pattern.

so you have to loop over the list.

Nick

PS. BTW, don't take this as an endorsement of the course you are
following.  I don't have the time to think much about it, and I don't
have a better solution, but personally, I would try to find another
method: my knee-jerk reaction was to use emacsclient if emacs is running
(if not, fall back to emacs --batch: since no other instance is running,
you wouldn't have to deal with locking in that case).  But that may or
may not work - I just don't know.

Understood. I though the batch method would be great until all of this
happened. All I want is some kind of agenda "snapshot generator" so I
can have a visible reminder of that's going on always present, whether
emacs is running or not. I'm running equipment and out of my office
all the time. I don't live in emacs and don't even have it open unless
I'm taking notes actively. Thus, having it on my wallpaper would be my
ideal solution as a reminder of what I need to do.

I should have been more precise. I meant to say in the context of the
current function or other functions which _accept_ wildcards as valid
arguments. Of course internally they use file-expand-wildcards, easily
verified by looking at the source of find-file. :)

No, you were precise enough, but I was too careless to see it (and of
course *knew* that find-file does not expand wildcards, even though the
last time I looked at the code or its doc was probably 20 years ago: I
have an inherent bias to assume that things don't change after I learn
about them :-) ).

You are right about find-file and friends re wildcards. I don't know why
this does not work:

$ emacs --batch --eval '(progn (find-file-read-only "~/lib/org/*.org" t) (org-batch-agenda "t"))' 2>/dev/null
Global list of TODO items of type: ALL
Available with `N r': (0)ALL

and nothing after it, but when I evaluate (org-batch-agenda "t") in
the running emacs, I get everything.

As I understand, with the above command the wildcard works but the file
locking prevents you from running it as a cron job. I could not find a
solution from a cursory search in the emacs and elisp manual. However I
have an alternate solution.

If you already have an emacs instance running, you could run your agenda
export as a timer within emacs. I don't know about the exact
implementation details, but I think you can find enough hints in the
following Worg entry in org-hacks.

BUG: Newest org-mode interferes with desktop save

[Rainer M Krug]

[-- Attachment #1: Type: text/plain, Size: 790 bytes --]

Hi

when using the newest version of org-mode (Org-mode version 7.5
(release_7.5.391.gfacc)), I get the following warning when closing emacs,

"Current desktop was not loaded from a file. Overwrite this desktop file?"

although it has loaded the desktop file. When I use 7.5 (and te one from I
guess yesterday), the message did not occur.

I have (desktop-save-mode 1) on my emacs.org.


Cheers,

Rainer

Re: BUG: Newest org-mode interferes with desktop save

[Eric Schulte]

Hi Rainer,

I was able to reproduce this query-on-close behavior with the following
minimal config.

#+begin_src sh
  emacs -Q -l ~/.emacs.d/src/org/lisp/org.el --eval "(desktop-save-mode 1)"
#+end_src

however, I think this prompting behavior is expected, and when I
switched to the following alternative

#+begin_src sh
  emacs -Q -l ~/.emacs.d/src/org/lisp/org.el --eval '(desktop-read "~/Desktop/")'
#+end_src

I received no prompt on exit.  As far as I can tell there is not an
Org-mode bug here, however I could very well have missed something.

Cheers -- Eric

Maybe this will help?

| desktop-save is a variable defined in `desktop.el'.

|    nil           -- never save.
| The desktop is never saved when `desktop-save-mode' is nil.
| The variables `desktop-dirname' and `desktop-base-file-name'

Might be, but my point is, that the behaviour has changed in org-mode - and
that should not be.

I can not reproduce your example, as I am getting an "can not open
org-entities", but have you tried it with org-mode 7.5 as well as the newest
git? My point is, that up to a recent git version (probably yesterday), this
question was *not* there, but it is there at with the newest git version.

I agree, that emacs should ask where to save if there is no .emacs.desktop
 if where to save the desktop file, but the final question

"Current desktop was not loaded from a file. Overwrite this desktop file?"

(which I did not see in your example) should not be there as the desktop
file was definitely loaded. I attache my emacs.org file for reference.

Hope this clarifies the issue,
Rainer

;; I have defined a function, ess-R-object-tooltip, that when

;; the object at point.  The information returned is
;; determined by which R function is called.  This is controlled
;; by an alist, called ess-R-object-tooltip-alist.  The default is

;; use the associated function.  For example, when the function
;; is called while point is on a factor object, a table of that
;; factor will be shown in the tooltip.  The objects must of course
;; exist in the associated inferior R process for this to work.
;; The special key "other" in the alist defines which function
;; to call when the class is not mached in the alist.  By default,
;; the str function is called, which is actually a fairly useful
;; default for data.frame and function objects.

** COMMENT TODO Syntax highlighting for functions in R NOT WORKING
  based on https://mail.google.com/mail/#label/Lists%2FESS/125131ed24688970
  The following code needs to be run in R:
  
  obj <- do.call("c", sapply(c("package:base", "package:stats",
  "package:utils"), objects, all.names=TRUE))
  re <- "(^[^.[:alpha:][:digit:]]|<-|__)"  # to remove "weird" functions
  obj <- obj[-grep(re, obj)]
  fpath <- file.path(Sys.getenv("HOME"), ".emacs.d", "R-function-names.txt")
  write.table(obj, fpath, quote=FALSE, row.names=FALSE, col.names=FALSE)

I have only tried to reproduce this with the newest version of org-mode,
and with that minimal setup I posted in my previous email.  With that
setup there was *no* prompt when exiting Emacs if the desktop
configuration had been loaded from a file -- i.e., the correct behavior.

I'd suggest trying to run from a similar minimal configuration, and then
see if the problem persists?  If so, then it is due to something else on
your systems aside form the Org-mode version (e.g., OS or Emacs), and if
not then it is due to interaction with something else in your config.

Sorry, I can't be of more help without the ability to reproduce the
problem.

Cheers -- Eric

I completely understand.

I created the attached init.el file. In my setup, ~/.emacs.d/org-mode is a
symbolic link. If I set it to org-7.7, everything works as expected desktop
is loaded and saved without question), but when linking it to the git
version, the desktop is loaded, but when closing it giveas me the above
mentioned question:

"Current desktop was not loaded from a file. Overwrite this desktop file?"

As I said, the desktop *is* loaded.

Hope you can reproduce it with this setup,

Rainer

Here's a caution: when desktop.el is loaded, it adds to after-init-hook a
function that reads the desktop file. However, after-init-hook gets called
"at the end of initialization": if you try to reproduce using something like

    emacs -q -l init.el

it's not going to work - after-init-hook gets runs "between the -q and -l"
so to speak, whereas desktop.el does not get loaded until init.el is loaded:
that initializes the hook too late to do any good.

Probably the best way to do it is to create a dummy user "foo", copy init.el
to /home/foo/.emacs and then invoke emacs as

   emacs -u foo

Using this method, I cannot reproduce the problem with or without org in
the init file: here's the one that I used which also sets a couple of
desktop hooks that make some noise which is recorded in the *Messages*
buffer - that helps to verify that things work according to
expectations:

--8<---------------cut here---------------start------------->8---
;;; -*- mode: emacs-lisp -*-
(setq debug-on-error t)
(require 'desktop)
(desktop-save-mode 1)
(add-to-list 'desktop-after-read-hook (function (lambda () (message "got a desktop file"))))
(add-to-list 'desktop-no-desktop-file-hook (function (lambda () (message "no desktop file read"))))

;;; I tried with and without the following five lines
;;; I also tried with them placed *before* the desktop stuff
(add-to-list 'load-path (expand-file-name "~nick/src/emacs/org/org-mode/lisp"))
(add-to-list 'auto-mode-alist '("\\.\\(org\\|org_archive\\|txt\\)$" . org-mode))
(require 'org-install)
(global-set-key "\C-cl" 'org-store-link)
(global-set-key "\C-ca" 'org-agenda)

There seems to be a problem with my .emacs.desktop files in combination with
the new org - if I close all buffer, quit, answer the question with yes,
re-open emacs, open the same file again, close emacs (no questions asked),
open emacs again, desktop file is read, close, no questions asked.

So I know how to fix it. I attach one .emacs.desktop which shows this
behavior.

Cheers and thanks for your patience,

Rainer

It might help to try to narrow down the problem to one of the buffers -
starting with the org buffers to begin with.

Start nuking the buffers till you hit the problem or the problem
disappears.

It may not be buffers it could also be one of the other "states"
(whatever that means) that the desktop persists across sessions.

OK - I hope I did what you suggested. My setup now:

a) created user foo
b) changed ownership of /home/foo recursively to me (rkrug:rkrug)
c) copied the attached .emacs file into foo's home directory
d) created directory ~foo/tmp
e) copied test.org, .emacs.desktop.error .emacs.desktop.noerror
f)
cd ~/foo/tmp
cp -f .emacs.desktop.error .emacs.desktop
emacs -u foo
quit emacs -- question there
g)
cp -f .emacs.desktop.noerror .emacs.desktop
emacs -u foo
quit emacs -- question not there

In the .emacs file, the load paths are set to the git version of org-mode.
If I set them to 7.5, no question at all.

Hope you can reproduce it now and it helps to pinpoint the problem,

Cheers,

Rainer

Gnuplot unevenly spaced non-numeric data plot?

[John Hendy]

[-- Attachment #1.1: Type: text/plain, Size: 788 bytes --]

Hi,


I'm interested in plotting with non-numeric data for the x component of the
data points but don't want to have the gnuplot default of automatic spacing.
Does anyone know a way to have a word displayed instead of a number but have
the words unevenly spaced according to a "hidden value"?

Example:

| 1 | x: where it should be on the scale |  y |
|---+------------------------------------+----|
| a |                                  0 | 10 |
| b |                                 10 | 20 |
| c |                                 11 | 30 |
| d |                                 40 | 40 |

Does that make sense? If I just had the table minus the 2nd column, it would
space a->d evenly as if they were 0,1,2,3 or something like that. I'd like
control over their spacing.


Thanks,
John

It does make sense and gnuplot supports this perfectly fine. From the
gnuplot info manual (commands > set-show > xtics), an example is:

: set xtics ("low" 0, "medium" 50, "high" 100)

however, how to get this from org into gnuplot is something I cannot
help with.  Sorry.  Maybe babel is the way to go but I wouldn't have a
clue where to start...

Gnuplot can certainly do it, but whether you can convince org-plot/gnuplot
to emit the right incantation, I don't know.

Try the following in gnuplot

        plot 'foo.data' using 2:3:xticlabels(1)

with the data file containing

,----
| a                                  0  10 
| b                                 10  20 
| c                                 11  30 
| d                                 40  40

Nick,

That works from gnuplot. Not sure about orgmode... I tried

#+PLOT: using:"2:3:xticlabels(1)"

which is not working. There's no "using" option mentioned on worg:
http://orgmode.org/worg/org-tutorials/org-plot.php

<http://orgmode.org/worg/org-tutorials/org-plot.php>Perhaps it's not
possible?

I could try the org-babel method but there seems to be less documentation on
this?

John

Problem solved with babel. I was able to get everything I wanted by piecing
together some examples from the mailing list and gnuplot examples/manual
around the web.

Thanks!

Good! Maybe you should post the babel solution for future reference.
Here is an org-plot solution for future reference: there is a script
option that allows you to use an arbitrary gnuplot script.  The org
manual (http://orgmode.org/manual/Org_002dPlot.html#Org-Plot) describes
it very well:

,----
| script If you want total control, you can specify a script file (place
|        the file name between double-quotes) which will be used to
|        plot. Before plotting, every instance of $datafile in the
|        specified script will be replaced with the path to the generated
|        data file. Note: even if you set this option, you may still want
|        to specify the plot type, as that can impact the content of the
|        data file.
`----

foo.org:
--8<---------------cut here---------------start------------->8---
#+plot:  type:2d script:"myscript.gp"
| 1 | x: where it should be on the scale | y  |
|---+------------------------------------+----|
| a |                                  0 | 10 |
| b |                                 10 | 20 |
| c |                                 11 | 30 |
| d |                                 40 | 40 |
--8<---------------cut here---------------end--------------->8---

myscript.gp:
--8<---------------cut here---------------start------------->8---
plot '$datafile' using 2:3:xticlabels(1)

Re: [For Worg?] Gnuplot unevenly spaced non-numeric data plot?

Okay, bounced attempts with both .zip and tar. We'll try this instead... the
"attached file" mentioned below is here:

https://sites.google.com/site/jwhendytank/home/org-gnuplot-writeup.zip

Let me know if this can be useful for worg. There's really nothing new that
can't be found, but it's tricky if you don't know what you're looking for.
The attached is the result of lots of digging on my part and some excellent
help from the mailing list. Included are gnuplot methods for:

- Setting axis titles with the #+PLOT method

Again, this info exists elsewhere, but this might be very nice to have on
worg. Perhaps this would serve as a nice primer for the beginner? I
footnoted everywhere I could to the original sources of my information
(mostly the mailing list and gnuplot-tricks blog).

I Certainly agree!

This does look like Worg material.  We're trying to beef up example
heavy language specific pages for each language supported by Babel.

This material you've compiled sounds like an ideal base for the gnuplot
page.  If you're willing/able to integrate this information into such a
Worg page that would be fantastic, and I'd be very happy to help, I've
just stubbed out the beginning of a gnuplot page on Worg which could
hold your compiled instructions and examples.

it should propagate to
http://orgmode.org/worg/org-contrib/babel/languages/ob-doc-gnuplot.php
within the next two hours or so

Cheers -- Eric

Cool -- I'm game. What exactly is required? Can my generated html just be
plopped in or should I revise anything? If there's an example page we're
modeling after I can rearrange the pieces to match that? I'm up for pretty
much anything. I'm glad it will make it to a useful place! I've no
familiarity with how to add to word so I'll definitely need some assistance.

I see the stub page, btw.


Best regards,
John

Whatever you think is best.  Other language pages are linked to from the
table at http://orgmode.org/worg/org-contrib/babel/languages.php#langs,
so they could serve as a model.

Worg is a git repository of org-mode files which are exported to html to
generate the resulting Worg web page.  To contribute you clone the git
repository, edit the org-mode files, and commit your changes.  See
http://orgmode.org/worg/worg-about.php for more information about Worg,
and specific instructions about how to contribute.

Thanks -- waiting for push access after registering at the cz git repo. I'll
check some of the other language pages and try to model it after that --
both in tone and organization. It shouldn't take much to tweak it.

I'll post back if I have further questions. I kind of anticipate them. For
instance, how do I include my .png files? Do I need to put them on some
other personal server (google doc/site) and have them link to those? Or is
there a Worg pic repository?

You can place pictures in the images/babel/ directory -- or

Beamer specific setupfile?

[John Hendy]

I use beamer a lot for work and decided to create a beamer-specific
setupfile to clean up my org files a bit. My files typically contain a
header like so:

---
#+latex_class: beamer
#+startup: beamer
#+options: toc:nil latex:t tex:t
#+latex_class_options: [presentation,bigger]
#+beamer_frame_level: 1
#+beamer_header_extra:
\usetheme[alternativetitlepage=true,titleline=true,titlepagelogo=../pics/pic.jpg]{Torino}
#+beamer_header_extra: \usecolortheme{freewilly}

#+latex_header: \usepackage{tikz}
#+latex_header:
\usetikzlibrary{decorations,arrows,automata,positioning,backgrounds}

#+latex_header: \usepackage{setspace}
#+latex_header: \setstretch{1.3}

#+latex_header: \usepackage{lmodern}
#+latex_header: \usepackage{booktabs}
#+AUTHOR:    John Henderson
---

I tried inserting the above into a file called =beamer-setup.org= and
simply doing:
---
#+setupfile: ~/org/aux/beamer-setup.org
---

This doesn't seem to work, however. My theme doesn't get picked up,
for example. If I put the contents into the file directly, I'm all
set. Any suggestions on why this might be the case?

Thanks,
John

C-c C-c on the setupfile line? The doc says

,----
| `#+SETUPFILE: file'
|      This line defines a file that holds more in-buffer setup.
|      Normally this is entirely ignored.  Only when the buffer is parsed
|      for option-setting lines (i.e. when starting Org mode for a file,
|      when pressing `C-c C-c' in a settings line, or when exporting),
|      then the contents of this file are parsed as if they had been
|      included in the buffer.  In particular, the file can be any other
|      Org mode file with internal setup.  You can visit the file the
|      cursor is in the line with `C-c ''.
`----

and when I try the export, it fails to find "freewilly.sty" (no surprise
there), which seems to show that the file *is* processed.

Yeah, I should have just posted an example with an included theme
instead of the one I usually use. I think I tracked it down. First, I
added =t= to the list of class options:
---
#+latex_class_options: [t,presentation,bigger]
---

I saw an effect on my frame alignment, which told me things were,
indeed, being read. It seems the issue was with using
#+beamer_header_extra. I don't know what that's supposed to be for,
but it isn't picking up the theme option. Actually... in searching for
what it's supposed to be used for, I ran across a mailing list post of
the same problem:
-- http://lists.gnu.org/archive/html/emacs-orgmode/2010-09/msg01011.html

Indeed, ditching beamer_header_extra for the theme setting and just
using #+latex_header... works.

Thoughts on fixing this?

The beamer exporter is searching the original file for #+BEAMER_* stuff, not
the setup file (and of course it does not find anything interesting there).

The latex exporter seems to find everything in the setup file however, so there
must be some mechanism for searching the setup file. If so, it should be
possible to crib it and copy it into the beamer exporter. But the devil, as the
saying goes, is in the details...

I think the magic for latex headers happens in org-infile-export-plist:
but the function has not been told about #+BEAMER_* stuff, so it'll need
the addition of a few more cases to handle the beamer stuff.

Great. Thanks for checking into this. I don't know how to fix it, so
I'll simply stick to #+latex_header, as this is working fine at the
moment. It's interesting that #+beamer_ options work from the file
itself, but not from the setupfile, considering it sounds like all the
setupfile line does it treat the contents as if it's in the file
itself. Something's getting lost in there.


Thanks again,
John

org-infile-export-plist parses the current buffer and takes care of
#+SETUPFILE: options (even recursive ones). It constructs an options
property list and returns it. The latex exporter stashes it into
org-export-latex-options-plist which is then consulted by the exporter
(in all cases, including the beamer case). The trouble is that
org-infile-export-plist does not know about #+BEAMER_HEADER_EXTRA
or #+BEAMER_FRAME_LEVEL, so it does not put them in the plist it
returns.  It is a trivial thing to add them however: they are exactly
analogous to LATEX_HEADER and LATEX_CLASS options, both of which
org-infile-export-plist handles fine.

This thread has been interesting for the effects it has had on my mail
reading experience.  I use gnus and I have gnus configured to parse
*some* org syntax for fontifying messages.

Interestingly, for these messages, org has tried to load in setup files!
With the original email message, I got the following error message:

: Cannot read file "/home/xxx/org/aux/beamer-setup.org"

and with the last line I quoted above from Nick's email, I got:

: Cannot read file "/home/xxx/options (even recursive ones). It constructs an options"

Fun!

The question is: I believe that I have only configured gnus to do
fontification on source code blocks and a few other constructs.  None of
the patterns I have specified includes general #+ lines.  I cannot see
how these #+SETUPFILE lines are being interpreted.  Any ideas of where
to look?  It must (?) be an org issue, not gnus per se, I believe.

Thanks,
eric

Umm, it turns out that gnus does indeed catch lines that start with #+:

,----
|     (org-meta-line
|      "^[ \t]*#\\+[[:alpha:]]+: "
|      "$"
|      mm-uu-org-src-code-block-extract))
`----

I need to investigate mm-uu-org-src-code-block-extract why this leads to
setup file directives being followed.  I do worry a little about
security implications, although there probably aren't any.

Side note: that regex doesn't capture all org mode directives!

Apologies for the noise.

Actually all the #+BEAMER_* options are ignored (I fixed the line
breaks, so that's not it). Everything else makes it into the tex file.
Seems something is broke.
