If a functions want to elide trigger the modification hooks it should
bind: inhibit-modification-hooks.

 From
http://www.gnu.org/software/emacs/elisp/html_node/Special-Properties.html:


modification-hooks
If a character has the property modification-hooks, then its
value should be a list of functions; modifying that character
calls all of those functions. Each function receives two
arguments: the beginning and end of the part of the buffer being
modified. Note that if a particular modification hook function
appears on several characters being modified by a single
primitive, you can't predict how many times the function will be
called.

If these functions modify the buffer, they should bind
inhibit-modification-hooks to t around doing so, to avoid
confusing the internal mechanism that calls these hooks.

Overlays also support the modification-hooks property, but the
details are somewhat different (see Overlay Properties).


Could you try to find out the path from where these modifications
occur, insert a relevant bind there, and see if this helps?


I will try to track this down, yes.

[Orgmode] [babel] lob evaluation : a bug ?

Hi,

I try to evaluate function already defined in library-of-babel. 
But whatever the function I try to evaluate I have the following
error output get from buffer *Messages* :

setf: Wrong type argument: consp, nil

For example I use the following :

#+tblname: R-plot-example-data
| 1 |  2 |
| 2 |  4 |
| 3 |  9 |
| 4 | 16 |
| 5 | 25 |

#+srcname: R-plot(data=R-plot-example-data)
#+begin_src R :session *test*
plot(data)
#+end_src

When I evaluate block it works (with C-c C-c).

Then when I try to evaluate the following line :
#+lob: R-plot(data=R-plot-example-data)

With C-c C-c on this line I have the following answer :
Local setup has been refreshed

With C-c C-v e, emacs asks me : Evaluate this code on your system ?
I answer yes and I have the message :

[Orgmode] How do you use call and lob in org-babel?

2010-08-05 Thread Inquisitive Scientist
Dear Experts,

I am confused about how to use lob and call in org-babel. First I
define a simple function like square:
#+srcname: square(x)
#+begin_src python
return x*x
#+end_src

A line like
: #+lob: square(x=2)
does not seem to produce any result either in the buffer or on export:
#+lob: square(x=2)

The same seems to happen with call:
: #+call: square(x=2)
#+call: square(x=2)

Instead, to get things to work I need to do something like:
: | 4 |
: #+TBLFM: @1$1='(sbe square (x 2))
to get:
| 4 |
#+TBLFM: @1$1='(sbe square (x 2))

Thanks,

 I'm on the fence about that one. I would definitely love an easier way

I don't see why typing

How about a function like this (just a quick hack):




binUlvhFRjRaT.bin
Description: application/emacs-lisp


and bind it to a sensible key, e.g

   `C-c M-l'


This avoids any problems with camel case syntax and is easy to use.

The function does not use the default link method yet (i.e. ID
locations) but I couldn't make that work yet.

The manual says of %i that The entire text will be indented like %i

[Orgmode] debugging sbe calls

2010-08-05 Thread Inquisitive Scientist
Dear Experts,

I *love* org-babel. In trying to switch a bunch of things to using it, I
have run into the problem that if I get the syntax slightly wrong, either
nothing happens (no output) or I just get something like ERROR. Is there a
way to understand what is causing the error? So far, I have resorted to
creating a checklist of common mistakes which I run through whenever
something doesn't work. I think many of these look like things which could
in theory be detected and warned or complained about. Any suggestions on
debugging would be much appreciated.

Below is a list of some common mistakes.

** common mistakes

*** forgetting colon on srcname

If you do the following (note the missing colon on srcname)

#+srcname Cube(x=3)
#+begin_src python :results value :export code
return x*x*x
#+end_src

then things won't work (e.g., you may get an error about global name
'x' is not defined which is pretty confusing).

Instead, make sure you have the colons and do

#+srcname: Cube(x=3)
#+begin_src python :results value :export both
return x*x*x
#+end_src

which gives

#+results: Cube
: 27

*** forgetting = in chained sbe call

Make sure you include the = sign in a chained sbe call like the
following:

| 512 |
#+TBLFM: @1$1='(sbe Cube (x Cube(x=2)))

If you forget the = as in
| 19683 |
#+TBLFM: @1$1='(sbe Cube (x Cube(x 1)))

or if you forget a quote as in
| #ERROR |
#+TBLFM: @1$1='(sbe Cube (x Cube(x=2)))
it won't work.

*** getting confused on sbe call

It's common to forget that the sbe syntax uses pairs *without* the
equal sign. Consequently, something like
| #ERROR |
#+TBLFM: @1$1='(sbe Cube (x=2))

won't work but something like

| 8 |
#+TBLFM: @1$1='(sbe Cube (x 2))

will do what you want.

Failure of lob and call on C-c C-c has been fixed (ec034ba) since the
release of the version you are using. I hope it's not too inconvenient

So #+lob and #+call are working correctly with C-c C-c in the current

 setf: Wrong type argument: consp, nil

they are not currently working with C-c C-v e / C-c C-v C-e.

I have made a patch to fix that but it will need to be discussed /

 For example I use the following :

 #+tblname: R-plot-example-data

[Orgmode] Export: Using LaTeX \timestamp and or customising title header

2010-08-05 Thread 'Mash
Afternoon,

I have started experimenting with publishing outlines to PDF, and have been 
trying to sort out basic styling, mainly because the default export looks 
terrible.

I disabled the title header as I want my first outline to be the first thing at 
the top of the page. The problem is that I would like to either customise the 
real header i.e. not have it centred; or be able to use \timestamp under my 
first outline which would display the file timestamp.

Is this possible because I can't get it to generate a timestamp on export? I 
have tried enabling timestamp:t but this also has no affect. I use #+TITLE: 
to prevent the title header from being displayed.

-
#+LATEX_HEADER: \documentclass[10pt,a4paper]{article}
#+LATEX_HEADER:

Hi Bastien, I've posted the backtrace, it should be in the thread, a
few messages earlier.

Thanks,

 Do you still have this error?
 Can you send a backtrace?

 I've implemented this.

 You can define the :html-resolution in `org-format-latex-options'.

 Please test and report any problem.

Am I right in understanding that if we increase html-resolution the
resulting images will come out larger in a web browser; i.e that there
is no way to maintain the images the same size while making them appear
sharper in a web browser?

 You can control the font size directly in the header but there doesn't seem 
 to be a way to use org-mode to control the resolution...

 BTW, I'm not exporting to LaTeX directly because I'm using PrinceXML to 
 convert the HTML file to a PDF.

Hi Uriel,

Could you tell us a bit about what the advantages of PrinceXML are? One
question I have is: is it possible to get vector graphics (ps, pdf)
incorporated into the resulting pdf? Is there an open source
alternative? (I've been doing this with print to file in the print
dialog box in a web browser in linux).

htmldoc (see http://www.htmldoc.org/)

It comes with a GUI and is free enough to be in Debian.

Not sure if it is that perfect, but when ever I tried it it worked.
Didn't use it for ages.  I use Org mode and LaTeX2e instead ;)

[Orgmode] text color + highlight

2010-08-05 Thread Vinh Nguyen
Dear list,

I was wondering if there is an easy way to markup the color of the
text for html output (and highlight as well).  When I prepare meeting
minutes I'd like to color some things and highlight certain things.
Right now, I am using emphasizing a major portion of the text.  It
would be great to have colors and highlights to draw attention to
certain items.

Thanks.
Vinh

That is supposed to work with the `listings' package.  I havent tried
that yet.

I still use my old LaTeX headers and write verbatim LaTeX code.  I'd
like to switch though, since it's a lot to type.

Here is an example:

  \begin{codeblock}
  \keyword{public function}~\func{\_\_construct}~(\increaseindent[15]\doindent
  \variable{\$instance}~=~\konstante{MAP\_STANDARD\_JS\_INSTANCE},\doindent
  \variable{\$z}~=~\konstante{MAP\_STANDARD\_ZOOM},\doindent
  \variable{\$centerX}~=~-1,\doindent
  \variable{\$centerY}~=~-1,\doindent
  \variable{\$highlights}~=~\keyword{true},\doindent
  \variable{\$spots}~=~\keyword{false}\doindent
  )\resetindent
  \end{codeblock}


Looks horrible, does it?

You can find the listings.pdf documentation here:

   http://www.ctan.org/tex-archive/macros/latex/contrib/listings/






Best wishes

 I do have my own WebDav server (Apache mod) but I'm a security guy so I
 only allow https.  Bad http, bad. :)

Even in your own private network? 

My setup was to have the webdav server only visible in my home wlan and
then sync the phone against that.

In case anyone has any enlightenment, a quick try suggests that htmldoc
doesn't work out-of-the-box on html produced by org-mode (error below).

/tmp htmldoc --webpage -f x.pdf x.html

Re: [Orgmode] Bug: inline image display not working when org-indent-mode active, follow-up

Hi,

In the past few weeks, I found that the overlays of inline images in

I believe I've tracked this down to the following patch,

http://www.mail-archive.com/emacs-orgmode@gnu.org/msg25738.html


snip


If a functions want to elide trigger the modification hooks it should
bind: inhibit-modification-hooks.

Could you try to find out the path from where these modifications
occur, insert a relevant bind there, and see if this helps?


OK, seems like I got it!

Issue 1:

The overlays would disappear when org-indent-mode was turned on.

Solution:

Simply bind inhibit-modification-hooks in org-indent-refresh-section. Do other 
functions in org-indent.el need this?  Possibly, but it seems like this worked 
in my basic testing.

This was actually tracked down to using pabbrev.el [2] in my org buffers.  Ugh. 
Since this isn't org related, there's nothing in org to fix, but on the very 
small chance someone else ever has their inline images disappearing in org-mode, 
and uses pabbrev mode, I fixed it by simply binding inhibit-modification-hooks 
in the let block in pabbrev-mark-add-word.
