[O] Bug in table export for latex? (underscore and ampersand)
I'm trying to export a table with the following cell:
BAT_30_CCR01_OUV_ZONE_PCE_30_2A_102__30_2A_101
The ampersand seems to be messing everything... I obtain this when I export:
BAT\_{}30\_{}CCR01\_{}OUV\_{}ZONE\_{}PCE\_{}30\_{}2A\_{}102_\_30\_{}2A\_{}101
For this to export normally, I would expect this:
BAT\_{}30\_{}CCR01\_{}OUV\_{}ZONE\_{}PCE\_{}30\_{}2A\_{}102\_{}\\_{}30\_{}2A\_{}101
Here is the difference:
102_\_30
102\_{}\\_{}30
The underscore isn't escaped, which results in an unwanted subscript in the
exported table.
Is this a bug?
Any quick fix?
Thanks in advance!
[O] [BUG] ORG-LIST-END-MARKER when exporting from within a babel block with an exclude or include tag
Ok, I know this a very specific application. Perhaps it's not even a bug and I'm using it the wrong way. Here is a minimum working example: #+TITLE: Test org file #+EXPORT_INCLUDE_TAGS: test2 * First heading :test1: Testing, 1-2, 1-2. * Second heading :test2: Because we can. ** Now a list - First item - Second item #+BEGIN_SRC emacs-lisp :results raw :exports results :var buffer-file-name=(buffer-file-name) (let ((org-export-babel-evaluate nil)); don't evaluate in 'recursive' exports (org-export-as-ascii org-export-headline-levels)) #+END_SRC If you export this file to PDF (C-c C-e d), babel will evaluate and export the file as ascii. However, the ascii file will have the undesirable ORG-LIST-END-MARKER in it. Here is the resulting ascii export: Test org file = Author: Date: 2012-01-15 23:51:47 Table of Contents = 1 First heading 2 Second heading 2.1 Now a list 1 First heading :test1: --- Testing, 1-2, 1-2. 2 Second heading :test2: Because we can. 2.1 Now a list === - First item - Second item ORG-LIST-END-MARKER Any idea on how to fix this?
Re: [O] Including source when exporting in PDF
This babel block should do the following:
- When exporting, automatically tangle the babel blocks.
- Then take the resulting files and add them to a zip file, along with
the original .org file.
- Add the necessary \usepackage and latex commands to insert the zipfile.
Let me know if something isn't like you want.
Here is the babel block to add to your source (org) file:
#+BEGIN_SRC emacs-lisp :results org :exports results :var
buffer-file-name=(buffer-file-name)
(let ((filename (file-name-nondirectory (file-name-sans-extension
buffer-file-name
(shell-command
(concat zip -j filename .zip filename.org
(mapconcat '(lambda (arg)
(convert-standard-filename
(expand-file-name arg)))
(org-babel-tangle)
)))
(concat #+LATEX_HEADER:\\usepackage{attachfile2}\n
#+LATEX: \\vfill \\textattachfile[print=false,color=0.5
0.5 0.5]{filename.zip}{Source (.org) \\ other files...}\n))
#+END_SRC
==
On a related note, I've added some improvements to my own way to
export in multiple format and add the files along with the source. The
latex commands and usepackage are included, so no need to add them
elswhere in the org file:
==
# Make sure this babel block is the last one in the buffer;
# block after this one won't be evaluated before the txt and html export.
#+BEGIN_SRC emacs-lisp :results org :exports results :var
buffer-file-name=(buffer-file-name)
(let ((org-export-babel-evaluate nil)); don't evaluate in 'recursive' exports
(save-window-excursion ;; avoid leakage when more than one org export in block
(org-export-as-ascii org-export-headline-levels))
(save-window-excursion (org-export-as-html org-export-headline-levels))
(let ((filename (file-name-nondirectory (file-name-sans-extension
buffer-file-name)))
(to-include-files (directory-files (file-name-directory
buffer-file-name
(shell-command
(concat zip -j filename .zip
(mapconcat '(lambda (arg) arg)
(remove-if
'(lambda (file)
(string-match
\\.$\\|\\.pdf$\\|\\.atfi$\\|\\.tex$\\|# file))
;; don't include useless files
to-include-files)
)))
(concat #+LATEX_HEADER:\\usepackage{attachfile2}\n
#+LATEX: \\vfill \\textattachfile[print=false,color=0.5 0.5
0.5]{filename.zip}{Source (.org) html, txt...}\n)))
#+END_SRC
==
Enjoy!

Yes - and the files do have different extensions (e.g. .R, .sh, .sub,
none) and are not tangled necessarily in a specific directory.
and the original org file, but that is not a problem.

Hope this helps!
By the way, I can't get the code block to be evaluated

I assume, it is caused by the :exports none - so no evaluation is done
on export. Try changing it to :exports result and then generate an
empty result, or a list of files included in the zip file.

I think this practice may not actually require any changes to

[O] Org exports leaking into each other?
I'm trying to do simultaneous exports of an org document by doing the following: #+begin_src emacs-lisp (org-export-as-ascii org-export-headline-levels) (org-export-as-html org-export-headline-levels) #+end_src Each export done manually is fine, but when done like my code, the .txt file seems to be leaking into the .html file. Any suggestion to fix this? Also, when I export a babel latex code, it asks me if I want to evaluate. When I I export a babel /emasc-lisp/ code however, it doesn't ask me for anything and goes straight by. I would like it to be executed at each export, if it's possible. Thank you in advance!

[O] Exclude column from table when exporting
Is there a way to exclude columns when exporting a document containing tables? I know it is somewhat possible by using radio tables and :skipcols, but that would be a problem. I have _many_ tables and duplicate each of them, in addition of naming all of them, would be really complicated. I'm searching for a solution similar to the exclude row method /. Thanks in advance!

Re: Re: [O] Why does a column's name need to start with a letter? Changed source with no perceivable
Yes, it's very well explained, thank you. I'll try to encode my names by removing any - and by adding a dummy letter at the beginning. Is there another way of doing simple database in org-mode? By putting a component's name in a cell, I would like if the other columns could fill them-self with the component's characteristics.

In you example $10K-AN-D8, D8 is already a field reference, so Org does not know if you mean $10K-AN - @8$4. Furthermore, you could easily arrive at variables like $10-AN-D8, and then what should the $10 mean? Of cause one could disambiguate heuristically by checking which names have been defined. In fact, name replacement happens first, and this is why your patch appears to work. But the side effect would be that introducing new names could change the interpretation of an existing equation. All this is unstable and unpredictable. Hope this makes it clear. - Carsten
[O] Why does a column's name need to start with a letter? Changed source with no perceivable side-effects

However, I'm reluctant to use this feature; surely there was a reason for this limitation. Could someone point it out for me? If there's no reason not to name columns as we want, perhaps it could be modified in future versions? Thank you very much in advance! Christian
