Bug report: org-preview-latex fails when using tramp

[Dov Grobgeld]

Hello,

Since the instructions say that bugs should be reported on the mailing
list, I do so here.

When visiting a file by tramp over ssh, doing latex preview fails.

* Version

Tag 9.4.6 (commit:652430128)

* To reproduce:

Create the following org file:

#+begin_example
* Testing formulas
\[\xi^2+\chi^2\]
#+end_example

and invoke =org-latex-preview=.

The result is that org-latex preview fails finding the temporary tex file
(which was saved on the remote server)

#+begin_example
This is pdfTeX, Version 3.14159265-2.6-1.40.18 (TeX Live 2017) (preloaded
format=latex)
 restricted \write18 enabled.

Please type another input file name

Re: Newline woes when exporting to mediawiki markup

[Dov Grobgeld]

Thanks for the help. I now updated the function `org-mw-item` to:

(defun org-mw-item (item contents info)
  "Transcode ITEM element into Mediawiki format.
CONTENTS is the item contents.  INFO is a plist used as
a communication channel."
  (let* ((type (org-element-property :type (org-export-get-parent item)))
 (bullet (if (eq type 'ordered) ?# ?*))
 (the-item (org-trim contents))
 (level (- (/
 (length (org-element-map (org-element-lineage
item) 'plain-list
  #'identity info)) 2) 3)))
(progn
  (org-element-put-property item :post-blank 0)
  (format "%s %s" (make-string level bullet) the-item

With this change the following org input:
```
* A section
Here is a list of things

- An item
- Another item
- A subitem
- Another subitem
- Back to first
```

Is output as:
```
= A section =
Here is a list of things

* An item
* Another item

** A subitem
** Another subitem
* Back to first

```

This is close to the required result though there is still a redundant
empty line before "A subitem". How can  I get rid of it?

I also have no idea why I had to do the expression $level/2-3$ to get
the correct number of asterisks.

Another complication that I am currently ignoring is how to nest 
and  lists. But that's ok for now.

Thanks again!

Newline woes when exporting to mediawiki markup

[Dov Grobgeld]

Hello,

I've been trying to use the ox-mediawiki.el export option to export from
org mode to mediawiki mode.

Unfortunately the exporting does a poor job of exporting lists. E.g. the
following org mode source:

```
* A section
  - An item
  - Another item
- A subitem
- Another subitem
  - Back to first
```

is exported as:
```

= A section =
* An item

* Another item

  * A subitem

  * Another subitem

* Back to first

```
The expected is:
```
= A section =

* An item
* Another item
** A subitem
** Another subitem
* Back to first
```
I tried to modify ox-mediawiki.el to solve the following two issues:

- Get rid of redundant newlines between exported list items
- Replicate the leading asterisk to reflect the indentation level of the
list.

To get of the newline I tried to rewrite the org-export "item" translation
function `org-mw-item` but I would either get no newlines at all between my
items, or an extra newline between two subsequent items.

I just noted that ox-mediawiki is derived from the html backend, so perhaps
the limitations are there.

I would appreciate any guidance of how to fix this.

Thanks!

[O] Quoting a REPL session in an org document

[Dov Grobgeld]

Hello,

I wonder if there is a "standard" way of quoting a REPL session in an org
document. Right now I'm using #example, but I wonder if there is something
richer. The ideal would be to get something that is syntax aware so that
anything after the "prompt" is syntax highlighted.

Here is an example of a session that I would like to include literally in
my document:

$ ipython
Python 2.7.14 (default, Mar 14 2018, 13:36:31)
Type "copyright", "credits" or "license" for more information.
IPython 5.3.0 -- An enhanced Interactive Python.
? -> Introduction and overview of IPython's features.
%quickref -> Quick reference.
help  -> Python's own help system.
object?   -> Details about 'object', use 'object??' for extra details.
In [1]: import pandas as pd
In [2]: df = pd.read_csv('/tmp/foo.csv')
In [3]: df
Out[3]:
  Animal  WeightColor
0   Bear 200Brown
1Cat   5   Orange
2Dog  10  Black
In [4]:

I would e.g. like this to look as follows in the exported document (but
with colored selectable text, not through an image!):

Thanks in advance!

[O] bug#11700: 24.1.50; Bad interaction between BiDi and org-tables

[Dov Grobgeld]

The correct Unicode≥6.3 way to do this would be with the unicode isolation
characters. I.e. you would wrap each of the columns with column
contents. Does emacs honor these? Should be easy to test.

[O] org-mode, file-link, tramp, and smb domain

[Dov Grobgeld]

Hello,

In tramp the syntax for specifying a domain in a smb link is by using a
percentage sign [1]

//smb:user%DOMAIN@host:D/path/

but when trying to use this together with the org-mode file: link the
result is that it changes %D to ^M (control-M). Similar results are gotten
with other characters after the percentage sign. (If the letter is not in
the hexadecimal range, ^@ (null) is received). Even %% does not escape the
percentage sign.

Is there any easy workaround?

Thanks!
Dov

Re: [O] Table with images export to LaTeX

[Dov Grobgeld]

Some further probing showed that it worked by me as well! But with one
LaTex related restriction that I missed. The included filename must *not*
include more than one period! In my original file I had part of the
experiment conditions encoded in the name, e..g. lc-p0.5.jpg . This works
fine in HTML but fails in LaTeX.

Running pdflatex on the tex file yields:

! LaTeX Error: Unknown graphics extension: .5.jpg .

The problem has nothing to do with the org exporting, and is a LaTeX
limitation that I can live with. Case closed. :-)

Dov​

 Works for me with recent org.  What version of org are you using?  What
 is a /big mess/ more precisely?  It could be useful to post the bit of
 LaTeX generated for the table.

 How big are the images? Maybe set org-latex-image-default-width, for
 instance?  I often have something like this in documents where I am
 going to change the default image size for LaTeX export frequently:

 #+begin_src org
   # -*- org-export-allow-bind-keywords: t; -*-
   ,#+bind: org-latex-image-default-width 2cm

Thanks. Indeed I am using an older version of org. Adding grffile to
org-latex-default-packages-alist solves the problem.

 This should not happen in a recent version of org 8.3 as grffile was added

[O] Table with images export to LaTeX

[Dov Grobgeld]

I tried to export a table with four images to LaTeX, but got a big mess as
a result. In contrast, the result in HTML export is fine. Has anyone had
better experience and can recommend some remedy?

Here is an example of an input org file:

 | Image type | Low contrast| High contrast   |
 |+-+-|
 | Gray   | file:lc.jpg | file:hc.jpg |
 |+-+-|
 | Binary | file:lc-bin.jpg | file:hc-bin.jpg |
 |+-+-|

All the images are 200x200 pixels.

Re: [O] [OT] djvu?

[Dov Grobgeld]

A number of years back I was very excited about DJVU and used it to
compress my scanned documents. But at a certain point did I realize that
scanned bitmaps (as well as TeX'd documents width pk fonts) in PDF were
just as small, and I stopped using it, as PDF is much more widely
available. I'm not sure if the almost equal sizes of djvu and postscript
were because bad djvu compressor or because the PDF compressors improved at
some point. I would be interested to hear if someone else has other
experience.

Re: [O] org-mode and python pandas

I returned to this issue recently and tried to get the ob-python to output
a table with a header, but didn't manage. Here is the code:

#+BEGIN_SRC python :colnames true
return [['','A','B','C'],
[0,0.628365,0.424279,0.619791],

Is there any way to do that besides using the :results raw option?

  It seems that the only way to get a table from python is by outputting
  a two dimensional python structure:
 
  #+BEGIN_SRC python
  return [[0,0.628365,0.424279,0.619791],
  [1,0.799666,0.527572,0.132928]]

  | 1 | 0.799666 | 0.527572 | 0.132928 |
 
  This seems quite limiting
 

 In most cases this is what one wants when returning data from python
 code.  The following elisp defined a panda code block, which is just
 like python, only it assumes that the results will be these sort of
 human readable strings instead of python code.

 ;; -*- emacs-lisp -*-
 (defun org-babel-execute:panda (body params)
   (let ((results
  (org-babel-execute:python
   body (org-babel-merge-params '((:results . scalar))
 params
 (org-babel-result-cond (cdr (assoc :result-params params))
   results
   (let ((tmp-file (org-babel-temp-file sh-)))
 (with-temp-file tmp-file (insert results))
 (org-babel-import-elisp-from-file tmp-file)

 With the above evaluated the following works

 #+BEGIN_SRC panda
 return ,A,B,C
 0,0.628365,0.424279,0.619791
 1,0.799666,0.527572,0.132928

  Another related question is if there is any support for header tables?

 Yup, you need to export as html5, and set the html5-fancy option to
 true. See the manual:

Re: [O] Most Recent Org Update

I had the same problem after pulling from git yesterday and worked around
it by doing:

; This is a bug work around
(defun org-element-cache-reset (optional all) (interactive))

before requiring org.

  You probably meant to type org-element-cache-reset... my guess is you

 No, that call was introduced in commit
 0cecf32a0ae559266555b96668dc305710366c96
 by Nicolas Goaziou.

 I faced with the same problem; I started a fresh session of Emacs with
 Org-mode from git but Emacs stuck showing me that message (Symbol's
 function ...).

 I don't know Emacs Lisp very well but according to the commit now
 'org-footnote-section' must call 'org-element-cache-reset' at
 initialization time (:set line in defcustom of 'org-footnote-section')
 and exactly that causes a problem.

 The workaround I found is to set 'org-section-footnote' to nil _before_
 (require 'org) in .emacs.

Re: [O] org-mode and python pandas

[Dov Grobgeld]

Thanks for the answers, but there is still something missing in order
to get it to work. Part of it seems to be connected to the python
parsing. E.g. the following translation of Eric's sh example doesn't
output correctly with python:


#+BEGIN_SRC python :results output
print ,A,B,C
0,0.628365,0.424279,0.619791
1,0.799666,0.527572,0.132928
2,0.837255,0.138906,0.408233
3,0.388080,0.146212,0.575346

#+END_SRC

#+RESULTS:

: 2,0.837255,0.138906,0.408233
: 3,0.388080,0.146212,0.575346


#+BEGIN_SRC python :results table

1,0.799666,0.527572,0.132928
2,0.837255,0.138906,0.408233
3,0.388080,0.146212,0.575346

#+END_SRC

#+RESULTS:

|

It seems that the only way to get a table from python is by outputting
a two dimensional python structure:

#+BEGIN_SRC python
return [[0,0.628365,0.424279,0.619791],
[1,0.799666,0.527572,0.132928]]
#+END_SRC

#+RESULTS:
| 0 | 0.628365 | 0.424279 | 0.619791 |
| 1 | 0.799666 | 0.527572 | 0.132928 |

This seems quite limiting

Another related question is if there is any support for header tables?
I.e. instead of this:

|   |A |B |C |
| 0 | 0.827817 | 0.664009 | 0.089161 |
| 1 | 0.170031 | 0.729214 | 0.110918 |
| 2 | 0.575918 | 0.863924 | 0.757536 |
| 3 | 0.682722 | 0.774445 | 0.992041 |

I want this:

|   |A |B |C |
|---+--+--+--|
| 0 | 0.827817 | 0.664009 | 0.089161 |
| 1 | 0.170031 | 0.729214 | 0.110918 |
| 2 | 0.575918 | 0.863924 | 0.757536 |
| 3 | 0.682722 | 0.774445 | 0.992041 |

I guess that if I start playing around with the python ob module, it
should be possible to get this working?

 This sounds promising, if pandas support csv output that will be
 correctly parsed by Org-mode.

 The package already has CSV export, so one could use that.  I don't know
 if you could echo the result directly to the output, all examples
 revolve around putting the CSV into a file.  For Org, TSV output would
 be more natural.

 Something like:

 from pandas import DataFrame
 from numpy.random import rand
 from sys import stdout
 df = DataFrame(rand(10,3), columns = list('abc'))
 df
 df.to_csv(stdout, sep=\t, header = True, cols=(1,2))

 I was completely unable to get ob-python working this morning, so I
 haven't tested it.  I'm using python3, build in python mode and elpy.

 In any case, the csv route might be better, as Pandas doesn't print
 the table if it's too big (try changing 10 to 1000 above).

Re: [O] Right-to-left text in org mode

 However, bidi-paragraph-direction is always buffer local when set. That
 explains why switching to other mode does not help.

 The solution is to set bidi-paragraph-direction to nil in org buffers with
 mixed LTR and RTL texts. This, however, might change the alignment of some
 headings to right-aligned. But the bidi markers now work just fine, so it's
 just a matter of placing them wisely.

 I appreciate the time you took for this little discussion. It helped me get

[O] org-mode and python pandas

[Dov Grobgeld]

Has anyone used org-mode with the python pandas package? Pandas is in
a certain way an alternative to R, but with the (for me) familiar
syntax of python. See: http://pandas.pydata.org/

Pandas is very much built to be used interactively, and it outputs its
data in space separated tabular format. E.g. in ipython:

In [1]: import pandas as pd
In [2]: import numpy as np

In [3]: pd.DataFrame(np.random.random((4,3)), columns=['A','B','C'])
Out[3]:
  A B C
0  0.628365  0.424279  0.619791
1  0.799666  0.527572  0.132928
2  0.837255  0.138906  0.408233
3  0.388080  0.146212  0.575346

Unfortunately this doesn't output as nicely when used from org-mode:

#+BEGIN_SRC python
import pandas as pd
import numpy as np

return pd.DataFrame(np.random.random((4,3)), columns=list('ABC'))
#+END_SRC

#+RESULTS:
: A B C
: 0  0.827817  0.664009  0.089161
: 1  0.170031  0.729214  0.110918
: 2  0.575918  0.863924  0.757536
: 3  0.682722  0.774445  0.992041

while I would like to have:

|   |A |B |C |
|---+--+--+--|
| 0 | 0.827817 | 0.664009 | 0.089161 |
| 1 | 0.170031 | 0.729214 | 0.110918 |
| 2 | 0.575918 | 0.863924 | 0.757536 |
| 3 | 0.682722 | 0.774445 | 0.992041 |

The question is how to get this? Here are a few ideas:

1. Write a general filter in the org-mode elisp than uses heuristics
to recognize ascii aligned tables and change these to org-tables.
2. Add to pandas the option of globally influencing the text
formatting so that it outputs something more parsable by org-mode.
3. Create a special language pandas that recognize the ascii aligned
tables and saves the need to import pandas and np?
4. And the obvious approach of writing a python function that writes a
org-mode parsable table and always call it as part of the return.

Which is the preferable approach? Any other ideas?

Dov

[O] Emacs completion on file:xyz links?

kill-visual-line to kill-line, as I didn't want to touch the org-mode

[O] org-src-notify-natively and variable-pitch-mode interaction

[Dov Grobgeld]

 I am typically using variable-pitch-mode=t when editing org-files. But
embedded source code I would like to have in a fixed-pitch font. This works
well when org-src-notify-natively is nil, but when turned on, part of the
source code syntax highlightening (in my case python) is also turned into
using variable pitch font. I realize this is because neither org-mode nor
the syntax highlightening engine have a full cover of the various semantic
parts, but both rely on the default font for part of their markup. Is there
any way to work around this?

Thanks!

 It does that already.  Use C-c C-l to insert a link, when prompted for
 the type, say file: RET.  Then you can use the usual emacs completeion
 interface to get filename completeion.

 What is missing though is completion when editing an existing link.
 IMO, that would be a worthy feature request.

[O] Different faces for different flavors of org-mode files

[Dov Grobgeld]

I wonder if anyone has written a solution for changing the face by some
kind of style-sheet that is set according to the type (or flavor) of the
org-mode file?

My main org-mode file is a journal where 1-star always is used to the
current date. I therefore like to have it small, e.g. 100% non-bold. 2-star
is 140% though.

On the other hand, when writing non-journal files, I would like to have
1-star as e.g. 160% to indicate a title.

Does someone have any idea of how to implement this?

Thanks!

[O] Making formatting of links in tables inheriting org-table

[Dov Grobgeld]

I like to use a variable font for my org-notebooks, which works very
nicely. But since tables are aligned by fixed number of characters, I use a
fixed font for tables. The problem is when I add a link within a table. The
link then gets the face 'org-link' and not 'org-table'. Is there any
posibility to apply the the attributes of the faces of both 'org-table' *and
* 'org-link' in that order to receive both properties, so that links
outside of tables are shown in variable fonts and links in tables in a
fixed font?

 Did you customize Emacs to dynamically determine the paragraph

 left-to-right.

Yes, I changed that. Org-mode appears to me to work fine in dynamic
Bidi mode, so I don't understand the reasoning that it was turned off
by default.

  [stuff deleted]
 To the Org maintainers: the resolved paragraph direction at character
 position N in the current buffer can be retrieved like this:

  (save-excursion
    (goto-char N)
    (current-bidi-paragraph-direction))

Ok, thanks. Perhaps I'll have a go at it on my own.

 I tried inserting tabs into the buffer before the vertical bars, but
 after reordering it still didn't come out right.

 ??? What exactly did you try?  You need to have a TAB before and after
 each '|' that's between the cells (the outer ones do not need a TAB).
 Like this (you should see this correctly in Emacs 24.1; move cursor
 with C-f to see the logical order):

 ‎|      אבגד    |       הוזחטי     |

 Isn't this what you wanted?

Yes. Great! This is indeed what I wanted. My mistake was that I tried
it with a tab character before OR after the vertical bar. This
solution should be really simple to implement in org-mode as it means
that instead of joining the table columns with spacevbarspace
as is currently done, you just need to use tabvbartab as well
as setting the tab width to 1.

But I just wonder, is there any other character (preferably white
space character) with the same end-of-segment-boundary properties as
tab, in case tab is used for something else in org-mode? Or is it
possible to take an arbitrary character, e.g. U+E0020, and bless it
with end-of-segment boundary properties and then use that in the
org-mode buffer?

As a side note, I really like the idea of end of segment separator,
and I wasn't aware of it when I wrote fribidi a long time ago. I
wonder if the semantics of the emacs segment separator follows the
Unicode Bidi Algorithm?

 Imagine you have a buffer with the following logical contents (using the
 convention that capitals are RTL characters).

 | abcdef | abc |
 | ABCDEF | ABC |

 I would like this to be displayed as:

 | abcdef | abc |
 | FEDCBA | CBA |

 The problem is that I want to each column of the table to be isolated
 (with regards to bidi influence) from other columns in the table. (Of
 course we also want to choose the table direction, but that is a
 different and solvable issue.) If there is no such separation, which
 is the behaviour currently get in emacs HEAD, then the resulting
 rendered buffer is:

 | abcdef | abc |
 | CBA | FEDCBA |

 Is this even solvable in the current emacs bidi model?

 Yes, it is.  The solution involves putting segment separators between
 the table columns.  These could be TAB characters or a display
 property whose value is (space . :width N) or (space . :align-to COL).

 Org maintainers, please ask if you need help in fixing this.

Re: [O] Inline LaTeX fragments in emacs buffer

[Dov Grobgeld]

Thanks for the help. It makes my coursera ml-class notes easier to read.

One issue I had when I tried exporting to HTML with the dvnpng option the
following equation:

\[
J(\theta) = - \frac{1}{m} \left[\sum_{i=1} ^m y^{(i)} \log
h_\theta(x^{(i)})+(1-y^{(i)})\log(1-h_\theta(x^{(i)}))\right]
  + \frac{\lambda}{2m}\sum_{j=1} ^n \theta_j ^2
\]

in the png output I got the following trailing text:ORG-LIST-END-MARKER .
Is this a known bug?

Dov

Re: [O] Inline LaTeX fragments in emacs buffer

I got it. Org-mode erroneously interpreted the + sign on the second row as
a list token. Rearranging the latex text so that it does not start with -
or + is a workaround.

Re: [O] Fast linking to files in private git repos through a hyperlink

[Dov Grobgeld]

Thanks for your suggestion Bastien, but unfortunately it does not directly
map to the shortcut that I implemented in my package. In my *old* syntax:

git:repo::file.txt

file.txt is a search pattern for a *file* with in the symbolic repo repo
which maps to a real repo through the hash variable my-org-repos. The whole
idea was that I wanted to be able to use the symbolic name as a shortcut.
In addition file.txt is not the path of a file in the repo, but a search
pattern for a file in the repo. In case of duplicates the user is prompted
to interactively resolve the file. In addition I would also like to add a
search pattern for a string in the file.

My problem is how to merge this syntax with the org-git-link.el which uses
the syntax

git:/home/user/repo/data/results.png::nobelprize

where /home/.../results.png is the name of the path to a file and
nobelprize is the name of a tag.

Both my linking and the org-git-linking are two different equally valid use
cases. My problem is how to merge both these use cases under a single
syntax.

Dov

 git:[user@?][repo-server]:[git-repo-itself]::[search-pattern]

 When user is set, the repo-server URL won't have a protocol
 (git will be used by default as a protocol.)

 When user is not set, the repo-server may contain git:// or
 http:// as the protocol.

 But I didn't test your packing, so I'm maybe shooting in the

Re: [O] Question about org-table

[Dov Grobgeld]

I assume that your problem is due the long names in the column named
protein. You can have org-table clip the columns to a more reasonable
length by adding a row that contains e.g. 20 in the column to clip. This
will clip the column to 20 characters. You can still edit the full column
contents by doing ~C-c `~.

Thus add the following new row in the beginning or the end of the table:

||| 20 |
||

move to 20 and press C-c C-c.

See: http://orgmode.org/manual/Column-width-and-alignment.html

Great! That must be a new addition that I missed. It is not perfect though,
as I use a variable font for org-mode, which is inherited by the embedded

way of preventing that so blocks are always in e.g. Inconsolata?

I found that the block background color may be changed by
org-block-background which is nice to make a visual distinction of source

But unfortunately not fully, because both source code (at least in python)
and org-mode make use of the default font. And since I change this at
org-mode startup to the variable-pitch the result is that I inherit this
in the source code blocks as well.

A solution would be that all org-mode faces would inherit a common
org-mode-face. You could then customize this font to a variable-pitch
without using the ~variable-pitch-mode~ command. Is this feasible?

Dov

 Great! That must be a new addition that I missed. It is not perfect
 though, as I use a variable font for org-mode, which is inherited by the
 embedded source code block when I turn on org-src-fontify-natively . Is
 there any way of preventing that so blocks are always in e.g. Inconsolata?

 I found that the block background color may be changed by
 org-block-background which is nice to make a visual distinction of source

   Most of the dependencies I already had or  installed them from

   not work because of permission issues, the command needs to run with

   The one dependency I could not solve was the 'dot' executable.  I

   One last remark; since this is an online publication, I think using

Re: [O] Different face for org-table fields with formulas

I had a look at the org-mode sources and found that this was quite trivial

changed to another couple of characters that may then be set in
org-emphasis-alist to whatever formatting I fancy.

[O] Idea, configurable markup

[Dov Grobgeld]

I got the following idea regarding the use of markup characters in org-mode.
Currently it is possible to use *bold*, /italic/ and ~verbose~ and a few
other markups. I would have liked to have this extended as follows:

   - Allow the toggling of the display of the formatting characters, *, ~,
   /, etc.
   - Allow a system that allows the user to invent his own formatting. E.g.
   «variable», 〈function〉, $math$, ⌞string⌟, or whatever the user fancies. All
   these modes should be defined in an org-mode variable and the display
   attributes should be configurable, just like any other custom org-mode font.
   If the user wants to expand beyond ASCII it should be up to him.
   - Alternately, use a system like varvariable/var where the tag var
   is user definable, just like the magic characters above. The display of the
   tags should be toggable. Just like for [file:foo.bar] where the [] character
   are hidden, should the tags be hidden until someone erases one of the two
   delimiters.

Note that this is nothing more than ideas at the moment, and I'll probably
never get around to implement any of it. Still I thought I'd share it if
someone would like to have a go.

Dov

Re: [O] org-edit-file ?

I'm not sure that emacs is the best tool to e.g. generate a template png

that any of the proposed solutions solves the file:foo.svg edit scenario,
where foo.svg does not exist yet. Also I would rather differentiate between
opening a few for viewing and opening a file for editing, as e.g. eog and
inkview are good for viewing, whereas gimp and inkscape are better for
editing.

[O] org-edit-file ?

[Dov Grobgeld]

I just thought of an idea that I wonder if someone has implemented.

While writing my journal I find myself wanting to insert a graphics file,
e.g. a svg file and I write *file:foo.svg* . After having written the name
I  enter inkscape to create the contents of the file. To do that I have to
run inkscape manually and eventually doing saveas and navigate to the
correct directory to save the file. So my idea is to have a a new command
org-edit-file that would:

   - If the file does not exist, copy a skeleton file to the filename or
   generate the skeleton file by an emacs-function or by calling an external
   application.
   - Call the configured editor application on the new file.

[Orgmode] Orgmode and Unicode characters

[Dov Grobgeld]

Even though this announcement looks very cool, this again reminded me of
something I've been thinking off when using orgmode. And that is the use of
unicode characters. With the latest versions of emacs that support unicode
and with rich fonts such as DejaVu Monospace, it is as easy to use unicode
characters as ascii. What I was thinking of is that the current ascii
graphics of e.g. tables could automatically be switched to box drawing
characters (http://en.wikipedia.org/wiki/Box-drawing_characters) when
pressing C-c or Tab. Other characters that could be used are automatic
replacement of leading asterisks to various bullets. Each indentation level
could be given a different bullets. E.g. *==▸, **==●, etc. I'm sure that
arrows and various brackets may also be useful for various contexts.

Of course the use of these characters would be configurable and would be
turned off automatically for buffers that are not UTF-8 encoded.

Perhaps I'll one day learn the inner workings of org-mode sufficiently to do
this myself, but if there is someone who meanwhile wants to pick up the
idea, you're welcome!

Dov

Re: [Orgmode] Orgmode and Unicode characters

[Dov Grobgeld]

The way I see it, within org-mode you wouldn't have to change anything in
your input, but C-c C-c or other hot keys would do the change automatically.
But I really don't mind if the underlying buffer stays the same, but only
the display changes.

Secondly, typing Unicode characters is pretty easy in emacs through its
input modes. I have recently working on a special input mode for the
key-starved N900 keyboard and it is really simple through quail. For box
characters, you may e.g. use input mode rfc1345 through C-\ rfc1345, and
then type:

drhhdl
vv vv
urhhul

which results in:
┌─┐
│ │
└─┘
Obviously the display of these fancy characters is only syntactic suger, but
so is the use of font colors in the buffer.

Dov

 I agree with Darlan that something using Emacs display functionality
 (like used by org-pretty-entities) could be preferable because it would
 preserve the underlying text.

I'm wondering over one thing though. When exporting to HTML, the ditaa

[Orgmode] Generated images in buffer

[Dov Grobgeld]

I'm still feel quite a newbie to org-mode and I've been looking for a way to
include dependent images within the emacs buffer, but I still haven't
found it.

As an example, assume that I have manully created a diagram with ditaa code,
and once I am finishede diting  I'd like to press a keystroke e.g. Ctrl-C
Ctrl-C and have the contents change to the generated output image, and the
ditaa code will be hidden. When subsequently navigating to the image there
should be some indicator that this is a generated image and some keystroke
should allow turning the image back to its source code.

The same idea could be used for any system generating images, e.g. LaTeX
formulas, asymptote, a python script using cairo, etc.

Similarly if the source code is svg I might not want to display the source
code at all (which might be large), but would like to invoke inkscape to
edit the svg data. This is better done by referencing the svg as an external
image, instead of having it inline, but I would still like to easily invoke
an editor application from within emacs with a simple keystroke.

So is this currently possible?

Dov

This can be taken care of by using the shell script that comes with ditaa,
i.e.:

ditaa  -r -S /tmp/org-ditaa27392h-V

But to do this from within emacs I need to patch org-exp-blocks.el as
follows:

-(unless (file-exists-p org-ditaa-jar-path)
- (error (format Could not find ditaa.jar at %s org-ditaa-jar-path)))
:
-(message (concat java -jar  org-ditaa-jar-path   args

-(shell-command (concat java -jar  org-ditaa-jar-path   args  
data-file   out-file)))
+(message (concat ditaa  args   data-file   out-file))
+(shell-command (concat ditaa  args   data-file   out-file)))

(You also need to erase the checking for the existance of dita.jar)

Wouldn't it make more sense to replace the variable org-ditaa-jar-path with
a new variable org-ditaa-command that by default contains java -jar
/old/value/of/org-ditaa-jar-path? This would allow replacing it with a
shell script. Would a patch be accepted, or do you prefer to remain backward
compatible?

On a related question. Since there is quite a lot of common code between
org-export-blocks-format-dot and org-export-blocks-format-ditaa (especially
if my patch is accepted), wouldn't it make sense to create a
org-export-blocks-format-meta that take all the differences between the
various export-blocks as parameters? This would simplify adding additional
org-export-blocks.

perl code on your system for the inline version, but not for the multiline
version. Is this a bug or did I miss something?

Re: [Orgmode] Why are src_perl{} immediately executed?

[Dov Grobgeld]

From the documentation I see now difference between inline and multi-line
behavior. Note that I did not wish to evaluate the code at all but just have
inline syntax highlighting in my html export. Is src_perl{foo()} for
evaluation only and not for source highlighting?

Thanks,
Dov

 You can customize this with the variable org-confirm-babel-evaluate

[Orgmode] org-htmlslidy

[Dov Grobgeld]

org-htmlslidy is an org-mode html export option that outputs the result in
HTML Slidy format, see: http://www.w3.org/Talks/Tools/Slidy2/#%281%29 .

The work in progress may be downloaded from:

https://github.com/dov/org-slidy

Note that the resulting output may be heavily modified by supplying
additional css setup. E.g. the following header to an org file may be used
to choose the color and icons used on the W3C pages (you have to download
them locally as well).

#+STYLE: link rel='stylesheet' href='blue.css' type='text/css'  / link
rel='stylesheet' href='dov.css' type='text/css'  /
#+BIND: org-htmlslidy-html-preamble-footer h1A perl test/h1
#+BIND: org-export-html-preamble div class='background slanty'img
src='graphics/w3c-logo-slanted.jpg' alt='slanted W3C logo' //divdiv
class='background'img alt='' id='head-icon' src='graphics/icon-blue.png'
//a/object/div

Thanks a lot to the author of org-s5, Yann Hodique! org-htmlslidy is just a
slight modification of his module.

  Do you have any idea of what wrong?

 After a quick look, it would seem that you're missing jquery.js and
 org-slides.js in your /~dov/s5test/ui directory

 Or maybe they're here, and there is a permission problem with those
 files ?

 In any case 
 http://imagic.weizmann.ac.il/~dov/s5test/ui/jquery.jshttp://imagic.weizmann.ac.il/%7Edov/s5test/ui/jquery.jsgives
 a 404 error. Same for org-slides.js

 The consequence is that S5 is activated, but the document is not
 transformed correctly to fit into the expected model (hence the garbage
 display)

 Hope this helps,

 Yann.

Re: [Orgmode] Re: s5 presentation

[Dov Grobgeld]

Thanks. Indeed after installing htmlize did the html export contain the
proper css formatting for keyword highlighting. But the generated html
(neither in s5 org mode nor in normal html mode) does not contain the
corresponding css for the syntax highllighted attributes (e.g. .org-string ,
.org-keyword, etc). But this is already outside the scope of s5-org and I'll
ask this in a separate question.

Dov

 Sure, but it's actually an org-mode question :)

  #+end_src

 Well, it just works for me. The HTML export takes care of highlighting
 code blocks (probably using htmlize or something similar). Then org-s5
 doesn't transform at all those parts of the document.

 In your case I'd say that probably the source code exporter might fail
 for whatever reason. Is it doing the right thing for regular HTML
 export ?

 Alternately, I might have configured something somewhere to have code
 highlighting enabled, but I can't remember :) (and definitely not
 anything specific to org-s5). Anyway I suspect the problem is more on
 the org-mode side this time, whatever it is.

 Yann.

[Orgmode] org-mode and htmlslidy

[Dov Grobgeld]

In looking for the perfect slide show generation from org-mode I have so far
checked the following and found that they have serious problems:

   - epresenter - Keyboard gets stuck, little control over display.
   - org-s5 - No support for pages overflowing, e.g. when showing a long
   slides I would like to scroll

Looking around the net I found the following javascript that seems that it
could do the job:

http://www.w3.org/Talks/Tools/Slidy2/#%283%29

How difficult would it be to connect it to org-mode? Am I right that it
would simply be a relatively small rewrite of org-s5.el?

Re: [Orgmode] org-mode and htmlslidy

Thanks. Didn't know that. But it seems like you are then placed in the
beginning of the html-page and have to search for the position of the slide
that you were at. Not something that you are likely to want to do in the
middle of a presentation. (This might make the audience long for
PowerPoint...)

 You can toggle s5 between slide view and ordinary web page view in the
 midst of a presentation.

 This also helps the audience realize that you're using something /way/
 cooler than Powerpoint...

Re: [Orgmode] org-mode and htmlslidy

Does beamer and impressive support scrolling? I assume not as beamer is
LaTeX based which also uses fixed paper size. The paradigm of fixed size
slides is imho a remnant from a time when slides were hardware and placed
on a overhead projector. I see no reason why shouldn't be able to scroll a
long slide during a presentation if you can't fit it all on a single screen
full.

Re: [Orgmode] org-mode and htmlslidy

[Dov Grobgeld]

In principle I agree with you 99percent of the time, as descrete slides define 
the pace of the lecture, but at the same time I'm against arbitrary 
limitations. And not being able to scroll is imho such a limitation. Here are a 
couple of examples that I believe justifies scrolling:

* A code listing. Splitting up a listing between two pages looses contents.
* A tall graph, e.g a flow chart.

In this sence I think that htmlslidy is better than s5.

 If you want scrolling, why don't you simply make a presentation using
 HTML with Org-mode? I mean, just show someone a webpage or two?
 
 Please understand I'm only curious, not hostile. To me, I just don't
 see why you'd want to combine presentations and scrolling... to me,
 the advantage of presentations is their fixed size. It forces me to
 focus on key points due to the limited real estate on each slide.
 
 Why not just make an outline in HTML (with all the pretty charts and
 graphs inserted) and project your talking points on a screen?

Re: [Orgmode] org-mode and htmlslidy

[Dov Grobgeld]

I tried warping s5-org this morning into slidy-org and I finally got it to
work with one small remaining problem. In the resulting HTML I have:

div id=outline-container-2 class=outline-2

which I want to change to:

div id=outline-container-2 class=class

What is the best way of changing that? I saw that s5-org is using some
jquery rewrites of the xml tree. Is that the best way of solving it? Is
there a possibility of doing this change directly in org-mode without
javascript?

Thanks!
Dov

 These are great examples of the point of being able to scroll. In
 fact, I haven't needed to do either of these yet in my lectures, so I
 didn't realize the value of scrolling.

 But if scrolling and zooming are essential... well, those are already
 built into the browser, so why not just use HTML (or org-mode
 translated to HTML)?

 You can always break up a slide by creating different pages and link
 them all together. I guess linking is the value added of something
 like slidy...

 Hi,

 I'm the author of this little hack, so first thanks for your interest :)
 You're right, the goal is to have it work by just exporting to html, so
 C-c C-e b should just work.

 I suspect that you might have not inserted the magic line
 ,
 | #+SETUPFILE: s5.org
 `
 at the beginning of the file you're trying to export as s5.

 Re-reading the README, I must admit it's far from being clear that the
 magic comes from there... (will fix that immediately)

 Does that help ?

 Yann.

[Orgmode] Migrating my current work flow to org-mode

[Dov Grobgeld]

Hello,

During the last few days I have learned about org-mode and I'm starting to
plan how to change my current work flow to org-mode. My current work flow is
as follows:

* At the beginning of every new day I create a horizontal line and a time
stamp.
* I use mediawiki == headers == for headers and * for bulleted items.

Here is the typical view for two days:

-
Monday 2010-11-08 09:49

Worked: 8:00-17:15

== Done/Todo ==

* Add parameter somewhere so that energy graphs take into account that only
part of the panel receives radiation. Do this in run_specific_site.py.
* Teach Alex about python.

== Meeting with Alex and Betty ==

* Todo: run simulation for Tumbaktu.
:
-
Tuesday 2010-11-09 8:31

Worked: 8:17-

== Engine changes ==

* All these will be changed to vectorMatrix  M[panel*2]
** ground_collect_matrix Ok
** sky_diffuse_matrix Ok
** sky_beam_matrix Ok
--

So now I am trying to figure out how to map this into org-mode. Here are
some observations and questions:

   - The horizontal rule is ok in paragraph mode.
   - The timestamp is ok by doing C-c .
   - But the worked line doesn't work if I try to use C-c C-x TAB as it
   complains Before first headline. I could turn the row into a header or
   just insert plain text. Is there a more elegant solution? I don't want to
   have the worked line indexed. Note that the worked line is used at the
   end of the month to summarize the amount of work hours.
   - Is there any way of separating headers from items? I like the
   non-symmetry of the == syntax for headers and * for items, but I guess I
   can get used to that.
   - At my previous work place I used the same notebook file for more than
   10years(!) of notes, and needless to say it got to be very big (around 100k
   lines). Can org-mode handle that size files?
   - How can I customize the exported HTML? E.g. I don't like the table of
   contents or the numbering of headers.

But alltogether org-mode looks great! I'm looking forward to use it both on
my desktop and in emacs on my N900.

Thanks,
Dov
