Using the ':results output' work around won't work on most of my code
blocks as these are typically longer and more verbose.  So, that really
is just a work-around.

I've tested your patch and it seems to work.  But it does seem to need
an analogous change in org-babel-R-evaluate-session to also cure blocks
with ':session'.

[O] [babel] return file from R

2015-12-17 Thread Andreas Leha
Hi all,

I think there is a bug in the handling of results of R src blocks.  What
is the suggested way to make an R block return a link to a file?  The
obvious way appends a newline character to the file link (which is
broken because of that).

Here is an example:
--8<---cut here---start->8---
#+NAME: TESTSRC
#+BEGIN_SRC R :results file
  a <- file.path("junk", "test.org")
  a
#+END_SRC

#+RESULTS: TESTSRC
[[file:junk/test.org
]]

[O] cache and lint

Hi all,

I just had an error (something including "search" and "wrong side" ...)

`org-element-cache-reset'.  Hence my question: Would it make sense to
include running `org-element-cache-reset' into `org-lint'?

Thanks a lot!

I am not sure about the possible values, though.  babel header arguments
usually take 'yes' and 'no' as values for TRUE and FALSE.  Examples are
:tangle, :comments, etc.
So, I have been using ':imagemagick yes' until now.

But on the other hand ':imagemagick no' is not doing the expected thing.

I know next to nothing about all the internals here, so I guess you are
right.  My motivation to write here was just to minimize the chance that
org-lint reports errors that are not caused by the document itself.

Exactly.  I guess my implicit question was, whether we should aim to
make :imagemagick accept 'no' as nil to be consistent with the general
org babel conventions.

As I get it, you would say: no.

(The next question would be whether we live with inconsistency or
whether we should switch the other header arguments backward
incompatibly use t and nil as well...)

Yes.  But usually my source blocks are more noisy and produce some

I think the problem is in the exported latex file rather than in the org
document.  While the org document indeed has one paragraph the exported
latex file does not.  I can reproduce this.

With this org document:

--8<---cut here---start->8---
* Test

I've long used the following construction for displayed equations in org
#
\[
u_i(c)=p_i\lambda
\]
#
which (i) gives nice space for reading equations in the org-source, and
(ii) nicely protects the display equation from (fill-paragraph) and
friends.
--8<---cut here---end--->8---


I get this latex doc (relevant part only):

--8<---cut here---start->8---
\section{Test}
\label{sec:orgheadline1}

I've long used the following construction for displayed equations in org

\[
u_i(c)=p_i\lambda
\]

which (i) gives nice space for reading equations in the org-source, and
(ii) nicely protects the display equation from (fill-paragraph) and
friends.
--8<---cut here---end--->8---

I agree that the paragraph should not be broken in the exported
document.  There are also other use cases for comments inside
paragraphs.

Andreas

I do not really follow the footnote problem (not using footnotes much)
with this.  But if removing the line following the comment works, then
I'd suggest to simply also comment that newline.

In my opinion comments are not newlines.  Exporting comment lines as
newlines makes it impossible to comment newlines, which might be
desirable -- see this thread.

But I might be missing the point here.

That is handy.  I would not have thought of that.

[O] [babel] noweb reference with default values

2015-12-14 Thread Andreas Leha
Hi all,

I'd like to hear your ideas on how to include noweb references to code
blocks in a way that the default values are used as parameter values.

Here is a little example:

#+PROPERTY: header-args:R :session *testR*

The background is that I like to use Org mode table to record small data.

#+name: datatable
| A |  B |
|---+|
| 1 | 10 |
| 2 | 20 |

Usually I want to pre-process and/or convert such data.

#+name: read_datatable
#+header: :var datatable=datatable
#+begin_src R :results none
  datatable$B <- 10 * datatable$B 
#+end_src

Later I would like to use that data in larger (R-) code blocks.  I'd
like such code blocks to DWIM:

#+name: some_code
#+begin_src R :noweb yes :results graphics :file testplot.png
  <>
  plot(datatable$A, datatable$B)
#+end_src

But they do not: They are not stand alone and do not execute -- unless I
executed `read_datatable' manually/by chance upfront.



My current solution is to export the table to csv and read that csv in
`read_datatable'.

If the result of `read_datatable' is a single table again (as in this
MWE) I usually return that to Org mode which works ok.  But often the
result is more complex than that.

I see two ways to go:
- I could serialize more complex objects to disk and return a file name.
  But I'd prefer to not go through disk.
- I could pass the same arguments as to `read_datatable' also to
  `some_code'.  But that is duplication and becomes quite convoluted in
  the case of several noweb references with several arguments each.

Any ideas how to do that better?

Thanks,
Andreas

Thanks!  I am aware of that possibility.  Should have posted a more
involved example.  This works if I only return a table.  Or something
else, that can be passed through Org.  But it fails for instance if the
result is a function (or more functions...).

Andreas

Try to run `org-export-dispatch' with a prefix from the second time
onwards (so, do C-u C-c C-e).

That is what it does for me.  As I said, you have to do the first export
the normal way.

And if you do not mind the todonote in the caption (should work, I
guess) this might work as well:

I am not aware of a central place for this.  But it is mentioned in
the backend specific manual pages of section 12.  For instance
[[http://orgmode.org/manual/Quoting-LaTeX-code.html#Quoting-LaTeX-code][Section
12.7.4 Quoting LaTeX code]] for the latex case.

Thanks for following up on this.  I also ran some tests now and confirm
what you see.  Test code below [2].

I'd say it is a bug if the results from evaluation differ between
manual evaluation and during export.

And even if it is not explicitely contradicting the manual [1] (which
does not say anything about finding references), I'd prefer if
references in COMMENT'ed sections are not found -- neither during export
nor during evaluation.  This would be more inline with my intuition of
COMMENT is equivalent to # (which is also suggested by the fact that
COMMENT is described in the section on #).

There are two ways to exclude subtrees from export: the COMMENT keyword
and the :noexport: tag.  I think what you want to use here is the
:noexport: tag.

Here is the difference:

- COMMENTing a subtree is meant to be (roughly?) the same as putting '# '
  at the beginning of all the lines from that region.

- The :noexport: tag will simply skip the region from export.

So, to me it is more surprising that the manual execution works.  For
instance, I might have two tables with the same name.  Then, COMMENTing
one of them should ensure that the other one is used.

HTH,
Andreas




Re: [O] problems with export and :cache

2015-10-30 Thread Andreas Leha
Hi all,

As a follow-up.  The caching produces un-expected results for call lines
'in the other direction' as well: Changes in the arguments to the called
code block do not invalidate the cache.

--8<---cut here---start->8---
* Test Cached Export

** A long running code block.
#+name: foo
#+begin_src emacs-lisp :var bar="baz"

** Cached Calls
Execute these calls one after the other.

For me, the last one does not call foo, but I expect it to do so.

Thanks a lot.  I applied your patch but it seems that your patch does
not solve the problem in this specific situation.  Or do I miss
something?

I agree and avoid the caching mechanism generally.  But all alternative
approaches do involve more work, so I am regularly tempted to use it
again.

Generally, I think that caching is a sensitive area.  And if we think
that it is unpredictable and advise people to stay off of it, we are
better off removing it than offering it in this state.  At least until
it behaves (more) predictable.

True.  But can you explain to me why it is not possible to disable the
evaluation of a call line?  If the evaluation of a code block is
disabled (:eval never) there is no evaluation and no results.  If I
specify ':eval never' at the end of the #+call line I do not get any
results either but the called source block is unnecessarily and
unexpectedly evaluated.

So, basically I would argue that

  #+call: foo("qux") :eval never

should do what it says an evaluate never, i.e. it should behave as

  #+call: foo[:eval never]("qux") :eval never

Just to add (maybe that belongs to point 4 anyway): And the caching

[O] [babel] :eval and #+call lines

2015-10-29 Thread Andreas Leha
Hi all,

Since this is not related to caching, I post this as a separate question
from [1].

I want to argue that specifying ':eval never' as argument to a #+call
line should transitively apply to the called block as well.

Here is the example:

--8<---cut here---start->8---
* Test
** A long running code block.
#+name: foo
#+begin_src emacs-lisp :var bar="baz"
  (sit-for 15)
  (message "bar=%S" bar)
#+end_src

** Calling

This should not execute anything IMO.
#+call: foo("qux") :eval never

I.e. it should behave as this:
#+call: foo[:eval never]("qux") :eval never
--8<---cut here---end--->8---

Andreas

[O] problems with export and :cache

2015-10-28 Thread Andreas Leha
Hi all,

babel's :cache seems to be ignored during export.  At least on #+call
lines.

In the example below the caching works fine for interactive evaluation,
i.e. C-c C-c on the #+call line returns immediately.

If I export the subtree with the #+call line, however, the code block
gets executed and the export is slow.

I'd expect no evaluation even during export.

Is this a bug or am I missing something?

Regards,
Andreas

Exporting this subtree will demonstrate my problem.  I expect the call

It seems that to get close to how you want your slides to look, you need
to customize the theme in either of beamer and reveal.

Depending on whether you prefer to do that in css/js or latex, you might
arrive there quicker.

This seems to a problem with your setup of preview latex.  It
should work just fine.

For me the following org file works as expected -- also with
previewing the equation.

--8<---cut here---start->8---
#+LaTeX_header: \usepackage{amsmath} %% needed explicitely for org-preview-latex


* Test align

\begin{align}
(x+y)^3&=(x+y)(x+y)^2\\
   &=(x+y)(x^2+2xy+y^2)\\
   &=x^3+3x^2y+3xy^3+x^3.\qedhere
\end{align}
--8<---cut here---end--->8---

I do not seem to have any special setup for previewing latex,
though...

Sorry to be of no further help.

(Untested!)

I suspect that this is due to org-latex-prefer-user-labels being
nil.  This will make Org mode inserting auto-generated labels.
Setting this to sth non-nil might work here.

As far as I can see, the difference is that some of the code blocks have
the header argument `:noweb yes', while others do not.

I do not know how to achieve working noweb extension during evaluation
but omitting noweb extension during export, though.

That is a very relevant question and I'd be interested in the answer as
well.  But I am not aware of any support by Org mode for this.

I guess calling `org-babel-expand-src-block' prior to tangling would
answer your needs?

This would be desirable not only for plotting code blocks, also data
passed to code block is 'lost' during tangling.

I think it would be good to have a source block header argument, say
`:tangleexpanded', controlling such functionality.

WDYT?

Andreas

That's what I feared.  So, you better go for the other suggestions in
this thread, the hook or calling the export from that same source block
-- now making sure not to evaluate the block again.

if all of this is for a single block, you can get away quite cheaply

#+begin_src emacs-lisp :results silent

Thanks for this!  One reason less not to upgrade Org mode.

Seems to work fine!

Just note, that it works for me only after exporting
 (when tested under emacs -Q).

What about including that into org?

The same protection as in the previous version seems to take effect
here:

  (defmacro by-backend ( body)
`(case (if (boundp 'org-export-current-backend) org-export-current-backend 
nil) ,@body))

Could you elaborate why that might be better?  Including it as a macro
like this has the up-side to be more general.n

I think that also other header arguments would benefit from such a
(org-)by-backend switch.

In former versions (pre-dating the handling of *.tikz 'images' by
ox-latex) of the tikz code in this thread, for example, the :results
argument needed to be set according to the backend as well

I see.  Another reason for me not to upgrade?   My org is quite old.

Good to know!  Thanks for the confirmation.  I missed that.

Note also that it might be necessary to include

 #+header: :headers '("\\usepackage{tikz}")

to the latex block.  This I only need when testing with emacs -Q.  Not
sure why, though.  I was under the impression that global
#+latex_headers should apply in latex source blocks as well?

This macro is from Eric Schulte initially.  And I guess I would be out
of luck adapting it to new Org mode versions as well.

I'd vote for a macro like this to be included in Org mode.  I think it
is quite useful to have and somehow extends the @@latex: ...@ constructs
to babel.  That way updates to org breaking this would be less probable.

Unfortunately, I don't have the time right now to even upgrade Org mode.
So, I cannot offer any testing/bisecting, I am afraid.

Best,
Andreas

[O] export (to gfm) with file local variables

2015-08-21 Thread Andreas Leha
Hi all,

How can I make my toy sample file below export properly to github
flavoured markdown (using ox-gfm)?

(Of course including the file local variables in exported *.md file...)

If I try I get

 Unless you've restored sanity by setting org-export-babel-evaluate to

 evaluation and export are distinct actions, and I don't see why they
 should be linked by default.

 Wild guess:

 Principle of least surprise: setting it to nil means results from Babel
 code are not refreshed before export, without user realizing about it.
 I think most users would like them to be up-to-date before export. It
 seems sane to me.

 The problem is that if the code blocks are non-trivial it slows down
 the export. Changing one line of documentation and exporting
 re-evaluates all the code blocks, which for me often takes several
 minutes. The defaults work for trivial examples, but not my real-world
 use. Since it's easy to make it work how I want it to via
 org-export-babel-evaluate I don't mean to complain too much. I posted
 mostly to make sure the OP knows about org-export-babel-evaluate, in
 case disabling code block evaluation on export makes sense for them.


I know that problem...

Decoupling code block evaluation and export has the problem of
decoupling code block evaluation and export ;-), though.  If you export
your document without evaluating first, how can you be sure that the
resulting document is based on the latest version of the code contained
in the code blocks?  So, from my point of view the default is the safe
option and, thus, fine.

 That seems to be caused by the empty lines in the Local Variables:
 section of the md file:

 If I get rid of them manually, I think it goes away (although I don't

 That seems to be an ox-md (or perhaps ox-html) issue however and I'm not
 equipped to wade into those waters. Assuming this is correct, maybe you
 can add a filter to get rid of the empty lines?


Thanks for following that up!  That is interesting.  How did you see
that file with the empty lines?  I do not get anything exported --
neither md nor gfm.

2015-08-21 Thread Andreas Leha
Hi,

Just a small comment.

[ ... discussion of :caching of evaluation results ... ]

 For purely R-based work, Charles Berry’s ox-ravel package
 https://github.com/chasberry/orgmode-accessories/blob/master/ox-ravel.org
 is a very interesting approach, since it relies on the cache feature of
 knitr, which is capable of automatically detecting cross-block
 dependencies like the example above under some circumstances
 http://yihui.name/knitr/demo/cache/.  It would be interesting to see
 if that approach could be used to override :cache handling for ob-R,
 while falling back on org-babel’s less intelligent features for other
 languages (or in R environments that don’t have knitr available). 

That would be just awesome!

Andreas

[O] ox-gfm and toc

2015-08-21 Thread Andreas Leha
Hi all,

I am confused about how tables of content are handled in ox-gfm.


If I let org-mode do the default toc (#+OPTIONS: toc:t) then the TOC
seems to work -- even without using the generated anchors for the
headlines.

Test file:

--8---cut here---start-8---
* Test File

With text.
--8---cut here---end---8---

exports to

--8---cut here---start-8---


- [Test File](#test-file)

# Test Filea id=orgheadline1/a

With text.
--8---cut here---end---8---

This does not even use orgheadline1.




If I disable the default TOC and include a TOC later via `#+TOC:
headlines 2` this toc is constructed in html and uses links to anchors.
But these anchors are not present in the md file anymore, so the TOC is
broken.

Test file:

--8---cut here---start-8---
#+OPTIONS: toc:nil

#+TOC: headlines 2

* Test File

With text.
--8---cut here---end---8---

exports to

--8---cut here---start-8---
div id=table-of-contents
h2Table of Contents/h2
div id=text-table-of-contents
ul
lia href=#orgheadline11. Test File/a/li
/ul
/div
/div

# Test File

With text.
--8---cut here---end---8---

which refers to non-existent orgheadline1.


Is this a bug in ox-gfm?

Best,
Andreas

 I don't. However, as explained already, what triggers the hang is

 What matters is the root of the corruption.

 I still get hangs from time to time, and `kill -12 $(pidof emacs)'
 always shows flyspell-mode in the mix. I never get hangs without
 flyspell-mode. I think this has been mentioned before, but I don't know
 if anyone went any farther with it. I still get hangs!

 I have set up my system so that Org asks for a buffer name every time

   -k.
  

 *** Custom Python Session Names

 https://github.com/jorgenschaefer/elpy/issues/383

 I want each python session to optionally have a unique name, so that I
 can run multiple sessions in multiple windows/buffers/directories and
 not have them interact/interfere.

 Here I've copied =elpy-shell-get-or-create-process= from =elpy.el= and
 modified it. I also have to modify =python-shell-get-process-name=.
 This all is fairly easy, except when executing from Org it gets more
 complicated, hence the special case if a function called from
 =org-ctrl-c-ctrl-c=. 

 #+BEGIN_SRC emacs-lisp :results none
   (defun elpy-shell-get-or-create-process ()
 Get or create an inferior Python process for current buffer and return 
 it.
 Customized by KDM to make dedicated sessions
 (let* ((bufname (format *%s* (python-shell-get-process-name t)))
(proc (get-buffer-process bufname)))
   (if proc
   proc
 (run-python (python-shell-parse-command) t nil) ;; DEDICATED!

 (if (equal this-command 'org-ctrl-c-ctrl-c)

   (defun kdm/orig-py-sh-get-proc-name (dedicated)
 Calculate the appropriate process name for inferior Python process.
If DEDICATED is t returns a string with the form
`python-shell-buffer-name'[variable `buffer-name'].
 (let ((process-name

   )))

 #+END_SRC

Thanks a lot for setting me on the right track!  I am quite surprised
(coming from ess as my interface to R) that multiple named sessions
aren't supported out of the box for python.

I use your code now, which in my use-case works great.  Only slight
variation: I set the default python process-name to the session name
using these two functions:

#+BEGIN_SRC emacs-lisp :results none
(defun al-org-babel-get-session (optional arg info)
  Return the :session of the current source-code block.
Will return
- nil if :session is given but not named
- \none\ if no :session argument is specified
- the session name otherwise
  (interactive)
  (if (org-src-edit-buffer-p)
  (let ((beg org-src--beg-marker))
(with-current-buffer (org-src--source-buffer)
  (goto-char beg)

(let* ((info (or info (org-babel-get-src-block-info)))

[O] named python session

2015-08-12 Thread Andreas Leha
Hi python users,

I have a simple question to all python users.  I have a source block
with a named python session, e.g. 
 #+begin_src python :results output :session mypy
   x = 1
   print x
 #+end_src

Now I
- execute that source block and then I
- edit that block in its own buffer via C-c '.

My question:
How do I associate that with the python process in *mypy*?

I am asked to start python when I run python-shell-send-region.

Thanks,

Re: [O] Block level specification for tex code html export method

2015-08-12 Thread Andreas Leha
Hi Haochen,

You can render svg from latex through org directly.  Here is a complete
example including a tikz diagram that that works on my system (once I
tackle a bug in PGF [1]).
It renders
- png by default (and for inlining the image into the org document)
- nothing for latex (directly include the tikz code into the tex document)
- svg for html


--8---cut here---start-8---
#+LATEX_HEADER: \usepackage{tikz}

First execute the second code block, to define the convenience macro
and to set the required new variables in ob-latex.el.  Then export to
HTML and to pdf to see the tree exported as an SVG image and as
embedded tikz respectively.

* Tikz test
Here's a tree, exported to both html and pdf.

#+header: :file (by-backend (html tree.svg) (latex tree.tikz) (t 
tree.png))

  Use dvisvgm instead of imagemagick to generate the svg file.

Re: [O] Block level specification for tex code html export method

2015-08-12 Thread Andreas Leha
Hi Haochen,

Sorry for not being clearer.  There is no imagemagick involved in the
svg generation if everything is setup correctly.  Instead the command
defined in org-babel-latex-htlatex is used.  My test file sets this to
to htlatex from tex4th [1].

At the time of the thread I linked to there was a bug in ob-latex,
though.  So, make sure to be on a recent version of org (containing at
least the commit 510e7037988d44151dea5b98631839fc8003dd57 from
2015-03-21)

Just for reference, here are the first lines of the svg that is produced
for me which look fine to me:
--8---cut here---start-8---
?xml version=1.0 encoding=iso-8859-1 standalone=no? 
?xml-stylesheet href=latex-28543ACk.css type=text/css?

 Hi Andreas,

 Thank you for your code example. I've tried almost the same code which
 I saw from the thread you referred (with the htlatex initialization,
 which I'm doing in my .emacs), and indeed got a svg file as
 expected. But the problem is that when I try to browse the HTML page
 in chrome, the image is shown as broken. I check the HTML source code,
 the image is presented in an img tag, pointing to the svg file. My
 first though was that the svg file isn't recognized because it's not
 served by a HTTP server instead of being a filesystem link. I then
 tried to use python SimpleHTTPServer, then python3 -m http.server (the
 python2 SimpleHTTPServer was serving svg with a wrong Content-Type)
 but without luck.

 Today, I tried svg again, and finally figured out the problem: the svg
 file generated doesn't contain a proper xmlns in the svg tag, so both
 chrome and internet explorer is interpreting it as a plain xml file
 instead of rendering it.

 I guess this is a bug with imagemagick, but when I tried to do some
 research on this problem I found nothing. Maybe I could find something
 with more researches, but I don't have time now, and PNG is fine for
 me.

 Still, Andreas, thank you very much for helping.

 Hi,

 I'm trying to include a diagram drawn with tikz in a document, but
 couldn't find an elegant way to conditionally export it as png when
 generating HTML output and raw TeX code when generating PDF. It is
 possible to use

 #+OPTIONS: tex:imagemagick

 to have tex blocks in the document exported as PNG in HTML, but since
 I have other formulas which will render much better with MathJAX other
 than embedded PNGs, i really don't want to do it. What I'm currently
 doing is to use something like

 #+BEGIN_SRC latex :file diagram.png :results value raw
 \begin{tikzpicture}
 \draw (0,0) grid (7,5);
 \draw (0,0) node[below left] {$A$};
 \draw (7,5) node[above right] {$B$};
 \fill (0,0) circle (2pt);
 \fill (7,5) circle (2pt);
 \end{tikzpicture}
 #+END_SRC

 #+RESULTS[da59bc402ce2d1055b5ff471ea7e398c4e0488f5]:
 [[file:diagram.png]]

 so that the diagram will be include in the HTML file as a png image,
 and the pdf file will also include it as a raster image.

 But this method is rather a workaround. I'd like to see a vector
 diagram in the pdf file, which could be achieved if there is a way to
 specify how a block of TeX source code should be handled when exported
 to HTML regardless to the global settings. So I propose an extension
 to #+BEGIN_LaTeX block so that a new header :html will control how the
 specific block will be handled when exporting to HTML. The possible
 values might be none, t, dvipng, or imagemagick. none will ignore
 the whole block when exporting to HTML, just like the current
 behavior; t will try to call MathJAX to interpret this block of TeX
 code; and dvipng and imagemagick will call dvipng or
 imagemagick to render a png file to be embedded in the HTML page.

 If that extension is supported, we could then left the global option
 tex:t while inline a tex powered figure with great convenience. For
 example, in my use case, I could then just used the following code to
 achieve what I want:

 #+BEGIN_LaTeX :html imagemagick
 \begin{tikzpicture}
 \draw (0,0) grid (7,5);
 \draw (0,0) node[below left] {$A$};
 \draw (7,5) node[above right] {$B$};
 \fill (0,0) circle (2pt);
 \fill (7,5) circle (2pt);
 \end{tikzpicture}
 #+END_LaTeX

 As I'm new to org-mode, I may missed something that I could use
 instead (although I searched the internet very hard). Please feel free
 to disagree on me and point alternative ways to achieve my goal.

 Thanks in advance.

Re: [O] org-html-use-unicode-chars breaks source code blocks

2015-08-08 Thread Andreas Leha
Hi,

[ deleted: discussion on beatification ]


 My initial reaction was to kill it as well.  But I might feel like this a
 bit to often (I feel the same way about headline keywords like COMMENT).

There has been repeated 'bashing' of the COMMENT keyword lately on this
list.  Let me just raise a voice in defence.  I do not mind the syntax
too much, but the functionality of commenting a whole subtree without
loosing the outline functionality is really handy.  Especially also in
distinction to the equally handy :noexport: tag.

So, even if there is probably not a high risk for the COMMENT keyword to
be dropped I just wanted to express my support for it.

Andreas




Re: [O] Babel and R: Call code block and output plot

Hi Stefan,

 Hi.

 I'm playing a little bit with R code blocks in babel and calling them
 in different parts of my document (e.g. showing output in the main
 part and the code in the appendix).

 With most code blocks (e.g. setting some variables or outputting a
 LaTeX table with xtable) this works as expected (thanks to all working
 on this; its really great).

 Now I wanted to show a plot, but the associated code should also be
 shown in the appendix. In this case CALL seems not to work (not plot
 file is created or its empty).

 Here is a small example of what I'm trying to achieve:

 #+TITLE: Plotting Test
 #+OPTIONS: author:nil date:nil email:nil toc:nil
 #+CREATOR: Emacs 24.5.1 (Org mode 8.2.10)
 #+STARTUP: showall
 #+PROPERTY: session *R*
 #+PROPERTY: exports results

 * Main Part

 Here I want to show some plot:

 #+CALL: myplot[:exports results]()

 * Appendix

 Here the code of the plot should be shown:

 #+NAME: myplot
 #+BEGIN_SRC R :results output graphics :exports code :file my-plot.pdf
 hist(rnorm(50))
 #+END_SRC

 Any ideas what I'm doing wrong or how to better achieve my goal?


You still have to specify the format of the results of the #+CALL line, as in
#+CALL: myplot[:exports results]() :results file

BTW, I also think the 'output' in :results is spurious.

This work for me:

 Not a bug IMO.

 Notwithstanding the R issue, I think trimming the output of a radio
 table is a bit aggressive. We cannot know if trailing (and leading)
 spaces are significant in the output format the user defined.

 I removed the trimming part in commit
 bf37cd09b128b4431e1dd1a538fbcc4be3615042.

 Let me know if you disagree with that change.

 I don't think the change broke anything that wasn't already broken.

 And my diagnosis was wrong - I was confused by a problem that remains:

 `org-babel-R-assign-elisp' is broken. Ragged rows in a table are filled 
 with  in each missing field; `org-table-to-lisp' returns a list of lists 
 of common length.

 `org-babel-R-assign-elisp' inspects that list to see if any element vary 
 in length. But they do not, and therefore `max' and `min' in the let* 
 varlist are equal and later on `ob-R-transfer-variable-table-with-header' 
 is always used.

 I think lom pik's example would not have failed had max and min differed 
 as `ob-R-transfer-variable-table-without-header' would have been used 
 instead.

 R src blocks ought to render missing elements due to ragged rows in a 
 table as NA, but this isnt the current behavior for this table:

 #+NAME: tbl-ragged
 | 1 | 2 | a |

 | 8 | 9 |   |

 It seems like the fix for this would be to prune any  at the ends of 
 lists in the value arg when beginning  `org-babel-R-assign-elisp'.

 But I am tired, so I'll defer trying this till another time.

 Best,

 Chuck

Thank you all for looking into this.  I have seen this as well and the
manual work-around (to put sth into the last cell) was getting really
annoying -- especially if the table was auto-generated by sth else.

While looking at handling tables, could I suggest to switch to csv
instead of tsv for the table passing?  I still see issues with tables
not separated.  (This happens only in preview (C-c C-v v) and not when
executing the block.)  I never had time to track this down, but I get
caught now and then.  Using csv should be more robust in this regard.

Thanks,

 And you (both) have `ess-eval-visibly' set to nil, right?

 I do statistical genomics, which can be compute intensive. Sometimes
 processes need to run for a while, and I get impatient having to wait.

 I wrote (and use) ox-ravel[1] to speed up my write-run-revise cycle in
 org-mode.

 Basically, ravel will export Org mode to a format that knitr (and the
 like) can run - turning src blocks into `code chunks'. That allows me
 to set the cache=TRUE chunk option, etc. I run knitr on the exported
 document to initialize objects for long running computations or to
 produce a finished report.

 When I start a session, I run knitr in the R session, then all the
 cached objects are loaded in and ready to use.

 If I write a src block I know will take a long time to export, I
 export from org mode to update the knitr document and re-knit it to
 refresh the cache.

 I have a similar workflow, only that I use a package like
 approach, i.e. I tangle function definitions in a folder ./R, data into
 ./data (which makes it possible to share org defined variables with R
 running outside org) and scripts, i.e. the things which do a analysis,
 import data, ... i.e. which might take long, into a folder ./scripts/. I
 then add the usual R package infrastructure files (DESCRIPTION,
 NAMESPACE, ...).
 Then I have one file tangled into ./scripts/init.R:

 #+begin_src R :tangle ./scripts/init.R  
 library(devtools)
 load_all()
 #+end_src


 and one for the analysis:

 #+begin_src R :tangle ./scripts/myAnalysis.R  
 ## Do some really time intensive and horribly complicated and important
 ## stuff here
 save(
 fileNames,
 bw,
 cols,
 labels,
 fit,
 dens,
 gof,
 gofPerProf,
 file = ./cache/results.myAnalysis.rds
 )
 #+end_src


 Now after tangling, I have my code easily available in a new R session:

 1) start R in the directory in which the DESCRIPTION file is, 
 2) run source(./scripts/init.R)

 and I have all my functions and data available.

 To run a analysis, I do

 3) source(./scripts/myAnalysis.R)

 and the results are saved in a file fn

 To analyse the data further, I can then simply use

 #+begin_src R :tangle ./scripts/myAnalysis.R
 fitSing - attach(./cache/results.myAnalysis.rds)
 #+end_src


 so they won't interfere with my environment in R.

 I can finally remove the attached environment by doing

 #+begin_src R :tangle ./scripts/myAnalysis.R  
 detach(
 name = attr(fitSing, name),
 character.only = TRUE
 )
 #+end_src

 Through these caching and compartmentalizing, I can easily do some
 things outside org and some inside, and easily combine all the data.

 Further advantage: I can actually create the package and send it to
 somebody for testing and review and it should run out of the box, as in
 the DESCRIPTION file all dependencies are defined.

 I am using this approach at the moment for a paper and which will also
 result in a paper. By executing all the scripts, one will be able to do
 import the raw data, do the analysis and create all graphs used in the
 paper.

 Hope this gives you another idea how one can handle long running
 analysis in R in org,

 Cheers,

 Rainer


 That is a cool workflow.  I especially like the fact that you end up
 with an R package.

 Thanks. Yes - the idea of having a package at the end was one main
 reason why I am using this approach.



 So, I'll try my again.   Is there there any chance to see working
 example of this?  I'd love to see that.

 Let's say I am working on it. I am working on a project which is using
 this workflow and when it is finished, the package will be available as
 an electronic appendix to the paper.

 But I will see if I can condense an example and blog it - I'll let you
 kow when it is done.


Thanks!  Either way, I am really looking forward to this.

 Andreas,

 It is now, or at least the relevant subset of it is at:

 https://github.com/chasberry/geneRx/blob/master/Rpackage.org

 It is best viewed in Org mode as there are internal links that github
 does not honor (so you get `404 This is not...' messages if you click
 on them).

 And it is best to use those internal links as the file was not
 designed to be read from top to bottom - it has lots of snippets I
 used to develop and check code along the way that are not in the
 actual package and I have left them in place.


That is awesome!  Really appreciated!  I will take a good look.

 3) source(./scripts/myAnalysis.R)

 and the results are saved in a file fn

 To analyse the data further, I can then simply use

 #+begin_src R :tangle ./scripts/myAnalysis.R
 fitSing - attach(./cache/results.myAnalysis.rds)
 #+end_src


 so they won't interfere with my environment in R.

 I can finally remove the attached environment by doing

 #+begin_src R :tangle ./scripts/myAnalysis.R  
 detach(
 name = attr(fitSing, name),
 character.only = TRUE
 )
 #+end_src

 Through these caching and compartmentalizing, I can easily do some
 things outside org and some inside, and easily combine all the data.

 Further advantage: I can actually create the package and send it to
 somebody for testing and review and it should run out of the box, as in
 the DESCRIPTION file all dependencies are defined.

 I am using this approach at the moment for a paper and which will also
 result in a paper. By executing all the scripts, one will be able to do
 import the raw data, do the analysis and create all graphs used in the
 paper.

 Hope this gives you another idea how one can handle long running
 analysis in R in org,

 Cheers,

 Rainer


That is a cool workflow.  I especially like the fact that you end up
with an R package.

So, I'll try my again.   Is there there any chance to see working
example of this?  I'd love to see that.

Re: [O] Emacs/ESS/org freezes/hangs on big data/ RAM(~256GB) processes when run in org/babel

2015-06-18 Thread Andreas Leha
Hi Chuck,

[snip: all context about workflows for R projects]

 For example, the bioConductor package geneRxCluster [1] comes from an
 Org mode document that contains the C and R code as src blocks and a
 subtree with the vignette (Using geneRxCluster) that analyzes data,
 produces graphics, etc. tangle-ing the src blocks and exporting the
 vignette creates the package.


I'd love to see that org document, but I do not seem to be able to find
it.  Is it available anywhere?

Thanks,
Andreas

 Sorry, this was the wrong diagnosis.  I get 'Before first heading' now

 I got myself into this by upgrading emacs [1].  I also upgraded Org
 mode [2] to no avail.

 What am I missing?

 Dunno. A backtrace with an uncompiled Org would help.


Sorry, I did not even test with emacs -q before reporting here.

I 'found' the problem.  The problem is outshine/outorg.  Disabling those
does solve the problem.

So, it is not really Org mode related.

 I thought this is a known problem which gets worse with the

I agree.  Although I do not actually experience this, as my custom LaTeX
classes all \use[ the ]package{grffile} (also in your Reference) by now.

I have not experienced any problem with that package and it appears to
handle more cases (especially spaces) than 'quoting'.  So, it might be
an alternative to use grffile by default?  Even with the downside of
more dependencies.  But maybe more experienced LaTeX users might have a
different opinion.

 Otherwise you could use e.g. imagemagick to stick together figures.


As an alternative you could use a table.
+ easy
+ orgmode only (should work across backends)
- no scaling of images
- it is a table for latex (i.e. will appear in list of tables, etc.)

Here is a short example for the table approach and an imagemagick-based
solution as proposed by Rasmus.


--8---cut here---start-8---

 The following library implements linting for Org syntax. The sole public

 calling the function `org-lint-NAME' with one mandatory argument,
 the parse tree describing the current Org buffer. Such function
 calls are wrapped within a `save-excursion' and point is always at
 `point-min'. Its return value has to be an alist (POSITION MESSAGE)
 when POSITION refer to the buffer position of the error, as an
 integer, and MESSAGE is a strings describing the error.

   - DESCRIPTION: Summary about the check, as a string.

   - CATEGORIES: Categories relative to the check, as a list of symbol.
 They are used for filtering when calling `org-lint'. Checkers not
 explicitly associated to a category are collected in the `default'
 one.

   - TRUST: The trust level one can have in the check. It is either `low'
 or `high', depending on the heuristics implemented and the nature of
 the check. This has an indicative value only and is displayed along
 reports.

 All checks have to be listed in `org-lint--checkers'.

 Results are displayed in a special *Org Lint* buffer with a dedicated
 major mode, derived from `tabulated-list-mode'. In addition to the usual
 key-bindings inherited from it, C-j displays problematic line reported
 under point and RET jumps to it.

 Checks currently implemented are:

   - duplicates CUSTOM_ID properties
   - duplicate NAME values
   - duplicate targets
   - duplicate footnote definitions
   - orphaned affiliated keywords
   - obsolete affiliated keywords
   - missing language in src blocks
   - NAME values with a colon
   - wrong header arguments in src blocks
   - misuse of CATEGORY keyword
   - coderef links with unknown destination
   - custom-id links with unknown destination
   - fuzzy links with unknown destination
   - id links with unknown destination
   - links to non-existent local files
   - special properties in properties drawer
   - obsolete syntax for PROPERTIES drawers
   - missing definition for footnote references
   - missing reference for footnote definitions
   - non-footnote definitions in footnote section
   - probable invalid keywords
   - invalid blocks
   - probable incomplete drawers
   - obsolete QUOTE section

 Since it relies on lexical binding, `pcase' and `string-prefix-p', it
 cannot be added to Org 8.3, but can make it into Org 8.4, if deemed
 useful enough.


 This sounds very interesting and I would like to try it out. I
 understand that it can't be put into master, but could it be put into a
 branch?

 This would make testing a bit easier.


 It is.  The branch is called `wip-lint'.

 Thanks (also to Nicolas) - I found it. Just expected the branch to be
 tracked automatically.

 This is really brilliant!

 But I now get a message in one .org file:

 ,
 | Org linting process starting...
 | Search failed: ^[]*#\\+NAME: +tab:sensVar
 `

 and no results.

 Works in other .org files.

 This one is rather long (11570 lines) and many code blocks.

 Just let me know how I can trace down where this is coming from and what
 the message tells me.

 It seems that the error comes from the fact that ~#+LABEL: sensVar~ was
 defined twice.

 Renaming these results in working linting.

 OK - please ignore this last comment.

 There is an example where I get the error:

 * Fitting the kernel to the data
 The parameter which will be fitted can be found in Table [[tab:fitInitial]]

 #+CAPTION: Variables used for the initial fit of the wind profile using the 
 function and the initial values.
 #+LABEL: tab:fitInitial
 | variable   | initial value | remark 
   |
 |+---+--|

 The cause is the link [[tab:initial]] If I remove everything below and
 including the line #+CAPTION the linting works.

 ,
 |  2 high  Unknown fuzzy location tab:fitInitial
 `


Untested - but should that not be
#+NAME: tab:fitInitial
rather than #+LABEL?

Hi Nicolas,

I have finally made some time to test this.  I get some
unexpected warnings:

   79 low   Unknown value myfile.R for header :tangle
  192 low   Unknown value none for header :results
22985 low   Unknown value never-export for header :eval

Thanks for this very useful tool!

Thanks,

[O] attachments in parent

2015-05-19 Thread Andreas Leha
Hi all,

As it seems, attachments are not found when they are attached to
a parental header.  Is that on purpose?

IMO, it would be nice if attachments would be searched for up the
hierarchy as well.  The attachment directory is not inherited, as
it seems.

Here is an example illustrating my question (you'll have to
attach something yourself to make it work, though):

--8---cut here---start-8---
* Example
** Test Attachments  :ATTACH:
:PROPERTIES:
:Attachments: sample_attachment.pdf
:ID:   B1024BF6-48F1-4300-9D0D-831A410BB40B
:END:

[[att:sample_attachment.pdf][This]] is found.

*** In Subsections

[[att:sample_attachment.pdf][This]] is not found.
--8---cut here---end---8---

Regards,
Andreas

PS: the relevant part of my setup:
--8---cut here---start-8---
(require 'org-attach)
(setq org-link-abbrev-alist '((att . org-attach-expand-link)))
--8---cut here---end---8---

 Nicolas Goaziou m...@nicolasgoaziou.fr writes:

 Hello,

 The following library implements linting for Org syntax. The sole public
 function is `org-lint', which see.

 Internally, the library defines a new structure: `org-lint-checker',
 with the following slots:

   - NAME: Unique check identifier, as a symbol. The check is done
 calling the function `org-lint-NAME' with one mandatory argument,
 the parse tree describing the current Org buffer. Such function
 calls are wrapped within a `save-excursion' and point is always at
 `point-min'. Its return value has to be an alist (POSITION MESSAGE)
 when POSITION refer to the buffer position of the error, as an
 integer, and MESSAGE is a strings describing the error.

   - DESCRIPTION: Summary about the check, as a string.

   - CATEGORIES: Categories relative to the check, as a list of symbol.
 They are used for filtering when calling `org-lint'. Checkers not
 explicitly associated to a category are collected in the `default'
 one.

   - TRUST: The trust level one can have in the check. It is either `low'
 or `high', depending on the heuristics implemented and the nature of
 the check. This has an indicative value only and is displayed along
 reports.

 All checks have to be listed in `org-lint--checkers'.

 Results are displayed in a special *Org Lint* buffer with a dedicated
 major mode, derived from `tabulated-list-mode'. In addition to the usual
 key-bindings inherited from it, C-j displays problematic line reported
 under point and RET jumps to it.

 Checks currently implemented are:

   - duplicates CUSTOM_ID properties
   - duplicate NAME values
   - duplicate targets
   - duplicate footnote definitions
   - orphaned affiliated keywords
   - obsolete affiliated keywords
   - missing language in src blocks
   - NAME values with a colon
   - wrong header arguments in src blocks
   - misuse of CATEGORY keyword
   - coderef links with unknown destination
   - custom-id links with unknown destination
   - fuzzy links with unknown destination
   - id links with unknown destination
   - links to non-existent local files
   - special properties in properties drawer
   - obsolete syntax for PROPERTIES drawers
   - missing definition for footnote references
   - missing reference for footnote definitions
   - non-footnote definitions in footnote section
   - probable invalid keywords
   - invalid blocks

 This sounds very interesting and I would like to try it out. I
 understand that it can't be put into master, but could it be put into a
 branch?

 This would make testing a bit easier.


It is.  The branch is called `wip-lint'.

Andreas

 Make sure you rebased the wip-lint branch on top of master.

 22985 low   Unknown value never-export for header :eval

 I added it to allowed value. You need to update Org.


I just pulled and rebased again.  The never-export issue is
gone, indeed. The others are still there.  What am I missing
here?

 Nothing. I overlooked a typo. It should be fixed in wip-lint.

Thanks.  Now the :tangle header argument does not produce a
warning.

But I still get

--8---cut here---start-8---
191 low Unknown value none for header :results
--8---cut here---end---8---


Ahh, and one more thing: The :tangle property in my test case was set
buffer wide through

--8---cut here---start-8---
#+PROPERTY: header-args:R :tangle myfile.R
--8---cut here---end---8---

But still, it produced a warning for each code block.  It would
be nicer if that warning was issued only once, IMO.  But that is
very minor.

 IMO, it would be nice if attachments would be searched for up the

I was reminded off-line that there is a
property (`ATTACH_DIR_INHERIT') controlling this behaviour.

I have even set that property in the past but only when I had
explicitly set the attachment directory as well.

Anyway, for future reference here is the MWE again, this time
working as expected:

** Test Attachments  :ATTACH:
