Re: [O] Using different image format given the export backend
Hello, #+CAPTION: Toto figure #+NAME: fig::toto #+ATTR_LATEX: :width 0.38\textwidth #+BEGIN_SRC emacs-lisp :exports results :results value raw (case (and (boundp 'backend) backend) (nil ) (latex [[file:./toto.pdf]] (html [[file:./toto.png]])) #+END_SRC I do it like this: (defun vb-massage-includegraphics (str backend opts) (replace-regexp-in-string .png} .pdf} str)) (add-hook 'org-export-filter-final-output-functions 'vb-massage-includegraphics) And then, simply refer to the png file in the .org file. Then nothing happens for the html output, but on latex export, the regexp matches the '}' and includes the .pdf file instead. That is extremely ugly, and makes plenty of assumptions, most of all that the .pdf file exists. And it should probably test for the value of 'backend'. But for personal use, it is convenient ... /v -- Vincent Beffara
Re: [O] Blank lines in date-trees
Hi Bastien,
Very (very!) minor question: when capturing into a date-tree, is it
possible to have a blank line inserted before created day-headings?
C-h v org-capture-templates RET
[...]
:empty-lines-before Set this to the number of lines the should be inserted
before the new item. Overrides :empty-lines for the
number lines inserted before.
Hope that helps.. and works :)
Thanks - but it doesn't ... More precisely, it does insert a blank line
before the new entry itself, but not before the higher-level month and
day entries that possibly need to be created. Like this:
a question raised in \citet*{BenArous}.

Re: [O] One more question on bibliographies in Org
The main question is: what would be a convenient way to store the references in the .org file, to allow for easy editing and exporting ? What I have done so far is to use some bibtex blocks, which tangle to an external bib files. It is sometime useful to have the bibliography divided in separate sections inside the org file. That sounds good for purely LaTeX/PDF exports, thanks for the suggestion. Now, how to do it for HTML ? Is it possible to choose the tangle format / destination depending on the current export backend ? -- Vincent Beffara
[O] One more question on bibliographies in Org
Hi,
Following the recent trend on the list, although this is not a question
about BibTeX as such, nor about the syntax to use for references within
the text, but rather about how to integrate references in an Org file to
be easily exportable. For now, a central database is not part of the
question, copy-and-paste is ok. The target would be mainly HTML and TeX
export. Here is a sketch:
For HTML: \cite{ABC09} would be mapped to a link to the bibliography,
something like a href=#ABC09[ABC09]/a (regardless of whether there
is such a reference). The bibliography itself would be part of the HTML
page, typically like footnotes right at the end, with some structure
kept (but styling would be done by ad-hoc CSS so nothing much needed
here).
For TeX: AMSRefs sounds good because it makes the .tex file
self-contained. \cite{ABC09} kept as it is, and the bibliography would
be a \begin{bibdiv}/\end{bibdiv} generated from the .org file.
The main question is: what would be a convenient way to store the
references in the .org file, to allow for easy editing and exporting ?
Idea 1: A new block type #+begin_biblio containing the data in whatever
form (but amsrefs makes sense, easily parsable for html export and
nothing to be done for tex export). While we're at it, maybe also
#+begin_bibentry if it helps cross-backend support.
Idea 2: #+begin_src amsrefs, and leverage babel for the output. But I'm
not sure if babel can act differently according to the export backend
being used?
Idea 3: A heading with tag :biblio:, which would be treated as a special
case at some point in the export, and containing one sub-heading per bib
entry, with properties storing the database like in org-bibtex (and
possibly unexported contents for notes). This gives access to structure
manipulation, refile, column view ... which would be awesome, but I'm
not sure how it would fit the export framework.
Which one would be best? Which one would be easiest to implement?
I'm willing to try a bit of coding, but the first step is the hardest
...
Cheers,
/vincent

[O] Choosing image format according to export backend
Dear list, I would like to have the same org file export to both PDF (through LaTeX) and HTML. The problem I have is images: for printing, PDF images would be best but for display in a browser, it is much better to have a PNG file rather than a link to the PDF. So what I need is for the exporter to choose the image differently according to the backend. I found this piece of code on stackoverflow: #+begin_src emacs-lisp :exports results :results value raw (case (and (boundp 'backend) backend) (nil ) (latex [[file:traps.pdf]]) (html [[file:traps.png]])) #+end_src That works, but I was not able to make it recognize captions and such (except by pasting them in both options or otherwise modifying the lisp code above). Plus the markup is a bit heavy. Is there a simpler way? [One thing I thought about was to keep only one of them in the markup, and modifying the output for the other backend. I kind of know how to do that within LaTeX by redefining the \includegraphics command but it feels ... well ... not elegant. Maybe using a hook during one of the exports?] Cheers, -- Vincent

Re: [O] OT: Annotating PDF Org
Given the emacs and Org oriented nature of this group, I'd like to know if anyone has found a good Orgish (ie: portable, text, etc) to annotate PDFs? Features would be items like highlighting blocks, adding notes (margins or sticky notes), and saving to either a sidecar file in a text format (ala Org) or directly appending the PDF. Not portable probably, but Skim (a very nice PDF viewer for Mac OS X) supports notes in an xml file next to the PDF, and something like this would make sense in a more general setting. Maybe using the same spec to be compatible? (Skim can then reexport everything as a single PDF file if needed, but a nice use-case for what you suggest would be something like personal org-mode reading notes on an article for which keeping them separate would make more sense.) /v -- Vincent Beffara

Re: [O] Org as a static site generator
Hi, I am using o-blog for that, it is pretty great. One Org file for everything, and it actually splits it into one page per marked headline. You can use one of the headlines as a template for the nav section of the page, shared across all pages. (As you can tell from the name, it is intended as a blogging tool, but you don't have to use it that way ...) The default template might not be to your taste (I don't like it at all, personally, so I made my own essentially from scratch) but you can customize it easily enough. And it might actually be close to what you are looking for.

I'd like Org to include the different exported files into the article section, and the rest to remain the same. The nav would contain a global navigation menu, also highlighting the current active section (though CSS, no JS please). I never quite managed to do that ... but it should definitely be doable. /v

The nav would contain a global navigation menu, also highlighting the current active section (though CSS, no JS please). I never quite managed to do that ... but it should definitely be doable. It's really simple to do. You just have to include some 'id' in the body which indicates to which section it belongs to. Yes, I mean, I know which html you need for that, simply within o-blog you need to manage between relative paths, absolute paths, canonical paths and so on in the template, to match the right section, - mainly it should be a matter of let-ing the right variable to the right value at the right point in the template and catching it when generating the toc, but I never took the time to get it right ... I've also just found this, which uses Org only as a markup tool and Jekyll to generate the site: http://orgmode.org/worg/org-tutorials/org-jekyll.html I had a look at the too, but it felt just a little bit too convoluted compared to managing everything from Org.

Re: [O] org-caldav will cease to work with Google Calendar
Hi, Supporting the Google Calendar API in org-caldav wouldn't be hard. It's actually a very clean, RESTful service; much better than CalDAV, in fact. Just what you would expect from Google. However, this is not a technical issue. This is also why I said that anyone who wants to implement support for the Google Calendar API in org-caldav should fork it; I won't accept pull requests which implement that. Actually I had a look at the API. It is indeed very clean, but there _is_ a technical issue, namely they limit access to a certain number of connections per day, and this is accounted per application rather than per user. Right now it is 10.000 a day, but just listing all events in a single calendar involves paging: for 200 or so events, I had to connect 7 times, and this counts as 7 connections. I have no idea how many org users would actually sync with google using their proprietary API (given there is support), but reaching the limit would be very quick, and very problematic. [Admittedly it is not a technical issue on their side, but it would be on ours, somehow.] If Google decides to discontinue a well established, IETF-standardized API in favor of a proprietary one for which there exist no free server implementations, I will not support that. I think the best solution for anyone using Google Calendar is to migrate away from that service. Agreed. Now to look for a replacement ... /v PS: In the mean time, for those who sync only from org to gcal, the option of exporting an ics file and hosting it somewhere for google to subscribe to is still available, but it is far from being as good.
Re: [O] org-caldav will cease to work with Google Calendar
Hi, First Reader, then this ... that was a bad press release :-( OTOH there is already some support for google APIs via the g-client package. One drawback of the package is that it doesn't work very well, at least on my machine many commands fail. Another one is that it seems not to have moved a lot for years. But it _can_ list my calendars, meaning that it can authenticate and have some sort of interaction with google's servers. Maybe interfacing with that would not be too hard?

Re: [O] org-caldav can't find org-prepare-agenda-buffers
Hi, Agreed ... I believe the only problem will occur when one of a multiply occurring event is edited / deleted on the cal side. I have nothing more constructive to propose than just don't do that ... My use-case is just as a way to push org changes to cal and nothing more, and for bidirectional people who would create events on cal and sync, not much bad would happen I believe. But you're right, conflict resolution (which is what that would be) will be a problem. Would have to manage reference counts etc, for little benefit. Who is using multiply occurring events anyway? Attached is what I am proposing: absent multiply occurring events, the org and cal IDs are the same (which is as it was except for the missing 1 in a regexp). For the second occurrence, the TS2- prefix is conserved, and so on - but it is trimmed when fed to org-id etc. As you say, it is not correct and will lead to problems down the road, but I really wanted all occurrences to appear in iCal ;-) Cheers, /v I appreciate your work, of course, but let me add a word of warning. I think if you give up the one-to-one correspondence that one Org event has exactly *one* event in the remote calendar, you are entering a world of pain. Remember that there are three things: new items, changed items and deleted items. Since these can happen on both sides, you have to figure out six different cases which must be handled properly. As you've already experienced, the changes on the calendar side are more difficult. What happens if you delete one of the events that stems from one Org entry? You would first have to figure out which timestamp created it, but how? Timestamps don't have UIDs, only the full entry has one. So you would have to somehow add this information to the event database which gets stored to disk. You might get this to work, but I have a gut feeling that you'll loose robustness. For example, the Google calendar CalDAV interface is pretty slow and not very reliable, so a robust resume functionality is essential. Also, I deliberately shoved conflict handling at the side for the moment, but this is a feature which will have to be added one day, and will complicate things much more. -David org-caldav-multi.patch Description: Binary data

Hi, Yes, I had the very same problem, I had to restart org-caldav from scratch a few times (org-caldav-delete-everything, wait a bit for caches to empty, and then eventually it worked). In the meantime I also tweaked the way org-caldav manages UIDs to exploit the fact that multiply occurring events are now exported multiple times in ox-icalendar, everything works out well if only org-ical is used. One thing remaining, on ical-org sync, there is an issue that makes the next sync erase the event on ical and upload it again, under another id (and with the info not generated by org-caldav missing, of course). I think I know how to fix it, just need to find some time ... I will send what works to the list.

Re: [O] Bug: New HTML exporter incorrect attributes
#+ATTR_HTML: :options width=\400px\ This is heavier but will be consistent with other back-ends. Otherwise, there is also: #+ATTR_HTML: :width 400px But this requires to have a list of all properties supported. How about both? I.e. a short-list of common options (class, title, id for links typically) plus a generic options as a back up to put whatever is not in the short-list ? /v, big fan of the ugliest solutions imaginable If we take that route, here is a suggested list of such properties for a tag: - rel - target - type - accesskey - class - style - title and for img - alt - height - width What do you think about it? The HTML exporter should produce valid HTML regardless of the input. We cannot remove the ability to shoot oneself in the foot. The HTML back-end cannot be responsible for undefined syntax. Think about: @@html:foo@@ The Org manual describes ATTR_HTML as a feature that applies to the following image or link. It makes no mention of restrictions to following content in the paragraph, and neither does it say it will apply to all following images or links. The manual could be amended to say that ATTR_HTML applies to just the next image or link. To fit the current situation, it might say, In cases where ATTR_HTML is applied to an image in a paragraph, following links will not be made invalid. But why would anyone be expecting invalid HTML in the first place? Incidentally, I always thought that simply using another HTML_ATTR would handle multiple images or links in the old exporter. In other words, this: #+ATTR_HTML: width=10 alt= [Cool thing] [[file:cool_thing.jpg]] This is a paragraph about cool things. #+ATTR_HTML: class=bar Cool thing found here [[http://example.com/][example.com]]. Would become this: p img src=cool_thing.jpg width=10 alt= [Cool thing] /This is a paragraph about cool things. Cool thing found here a href=http://example.com/; class=barexample.com (http://example.com)/a. /p I don't remember using that in the old exporter, but I thought it would work. It almost works in the new exporter, but it begins a new paragraph before the second #+ATTR_HTML. I'm not sure this is the intended behavior, though, because it isn't formatted like other new paragraphs. This is the intended behaviour. Affiliated keywords can only exist at the beginning of the element they refer to. So, in the previous example, you start two paragraphs. Alternatively, having ATTR_HTML (or something more general) apply to the next thing, and having that work within paragraphs, is another possibility. However, this may not fit within the limitations of the new parser. Plus it's kind of ugly. The parser won't support it. It goes against the definition of an affiliated keyword. Moreover, it's merely a hack (what about links in tables?). And it's ugly, indeed. Until there is a proper solution, however, could we please modify the exporter to apply ATTR_HTML to only the next image or link? I am very sure that was the spirit of the old exporter, and it would be nice if I could maintain my documents in Org without resorting to (even more) hacks. Done. Regards, -- Nicolas Goaziou

Hi, #+begin_theorem :options [Him] slkdfj #+end_theorem This isn't future-proof. If, for example, we need to add options for the HTML back-end, there will be a syntax conflict.

thanks for reporting this and for the patch, I've push a slightly different fix. Please test and let me know. Sounds good to me, thanks! ... well it did sound good to me, but it still fails. Put this in *scratch*, (org-html-format-latex x 'mathjax) and C-x C-e. Within org-format-latex, file-name-nondirectory is still called on the first argument (prefix) which your patch sets to nil. The error occurs one layer deeper in the tree but still does. My patch kind of fixed that by accident, but it should be safe at least in the case of mathjax which AFAICT will never create files anywhere - so simply testing on the value of processing-type would work better, maybe? /v /v Best, -- Bastien
Re: [O] New exporter, beamer confusion
Hi,
LaTeX class is never unspecified because `beamer' back-end is
a derivative of `latex', and, as such, `org-latex-default-class' will be
used. `beamer' could specify its own default class, but that class would
still need to be defined in `org-latex-classes'.
Sure, it should be in the default list. What is the drawback?
'(beamer
\\documentclass[presentation]{beamer}
\[DEFAULT-PACKAGES]
\[PACKAGES]
\[EXTRA]
(\\section{%s} . \\section*{%s})
(\\subsection{%s} . \\subsection*{%s})
(\\subsubsection{%s} . \\subsubsection*{%s}))
Looks reasonable.
Plain latex export is more problematic because several options are
reasonable, but I can't see beamer export with an article class ...
But it exists, and is documented in the Beamer User Guide. See section
21.2. Creating Handouts Using the Article Mode.
Yes, I know that, but the thing is, from a given org-file, I would expect
beamer export to make the slides and 'plain' latex export to create the
handout. Maybe it is difficult to achieve but it feels like the most useable
setup. Is it at all doable?

[O] LaTeX export: Theorem with an author
Hi,
How to generate latex code for a theorem with an author, like this:
\begin{theorem}[Newton]
Blah.
\end{theorem}
With the old exporter, you could do this:
#+BEGIN_theorem Newton
Blah.
#+END_theorem
(possibly with brackets, not sure) but now the rest of the #+BEGIN_ line is
ignored ... This works:
#+BEGIN_theorem
[Newton]
Blah.
#+END_theorem
but it is more by accident than anything else. What would be the right way?
Thanks,

[O] Archiving workflow suggestion?
Dear list, I am using org-mode to track various tasks, organized chronologically, like this: * 2013 ** January *** Task 1 *** Task 2 ** February *** Task 3 Once a task is completed I want to archive it, but I find it convenient to keep it within the same file for further reference. Optimally, using the archive sibling feature to save display space. So far so good, everything if fine. Once all tasks in a month are completed, I want to archive the month itself (so that the CONTENTS view is as clean as possible). But using the default methods builds an archive-within-an-archive situation. I realize it's not exactly a big deal (and the correct default behavior), but I would like to unarchive the children of a newly archived month automatically to make later traversal easier. Any suggestion how to do that? Or hints at a better workflow to achieve the same thing? Thanks, /v -- Vincent Beffara
[O] Bug in org-agenda.el (Was: Bad time display in agenda view)
Ha, I got it ! When displaying the end time of an interval in agenda view, org-agenda transforms the initial time stamp to minutes, adds the default length to that and maps back to a time stamp using org-minutes-to-clocksum-string. The problem being that this functions checks org-time-clocksum-use-effort-durations and if set to t, uses that in the formatting. Meaning that 8:00 is displayed as 1d 0:00 instead, and 17:30 as 2d 1:30 and so on. I am afraid to change the code, so I just customized org-time-clocksum-use-effort-durations to nil and everything works for now. But presumably this should be fixed by letting it be nil while formatting the end timestamp, somewhere near line 6404 of org-agenda.el ?

[O] Exporting to HTML without IDs
Hi, I want to manage my web page using org-mode, and to have a navigation bar also encoded in org. The problem is that the org-to-html conversion function adds IDs to all headers, and the same ids occur on the nav bar and the main content. Things link sec-1, outline-2 and so on. The words 'sec' and 'outline' seem to be hardcoded. Of course this makes html validators a bit nervous ... Is there a simple way to either remove those ids, or make them start at say 1001 for one part?

Re: [O] Exporting to HTML without IDs
Hi, Maybe adding CUSTOM-ID in your navigation bar would solve the problem. You don't say whether you use the old (current) or the new (in the to-be Org 8) HTML exporter?? Don't know, meaning probably the old one ... a CUSTOM-ID property is ignored, but it sounds like what I am looking for. Right now I fixed it by using (replace-gegexp-in-string id=\ id=\nav- navbar) in the template, but that implies having a template in the first place, which is not always the case. /v

Re: [O] Create preamble from an .org file ?
Hi, How do I do that? Maybe a dedicated .org file for the navigation bar is not the right way to do, is there a better one? Since you only need to export your preamble in HTML once, I'd rather use `org-export-html-preamble' and set it to the HTML string you want. Thanks for the tip. In terms of time spent to build a web page, that would have been the wise thing to do. However, I wanted something more modular, say being able to add a few pages without having to tweak the variable each time, and so on. So in the mean time I cobbled something together, which works for me and feels a bit more flexible if I want to modify the navigation bar in the page: (defun my-org-publish-org-to-html (plist filename pubdir) (org-pop-to-buffer-same-window (find-file ~/Boulot/org/web/preamble.org)) (let* ((preamble (org-export-as-html 3 nil nil 'string t)) (plist (plist-put plist :html-preamble preamble))) (org-publish-org-to-html plist filename pubdir))) (Everything is hard-coded, it should use the :base-directory and test whether :html-preamble is equal to 'file or something, and it does not feel optimal at all, if only because it exports the preamble once for every file - that's more like a proof-of-concept ...) The file .../preamble.org contains a few links and contact info, and the line to #+INCLUDE: the sitemap. Works reasonably well :-) and it could be something that others would find useful.

Hi, To manage my personal website I would like to use the publish function of org-mode. For the contents of pages, there is no problem, and the auto-sitemap feature is promising. however, I would like to have some common contents to all the individual pages, and they would best fit in the preamble part. Essentially, I would have a preamble.org file containing this: #+IMPORT: sitemap.org * A few links - link 1 - link 2 * Contact info - address - email and the contents of the preamble would be an html version of that (of course without all the head section and so on).

[O] Exported html structure
Hi, I would like to use jQuery to make the html exported by Org (un)foldable by clicking around, mimicking what tabbing does within emacs [except, I would like it if folding-and-unfolding-again kept open subtree as they were, which is a bit different from what org-mode does and is the root of my worry ...]. The structure of the HTML exported by Org is not optimal for that. Assume my org file looks like this, * Header 1 Some contents ** Header 1.1 Contents 1.1 ** Header 1.2 Contents 1.2 The HTML output looks like that (some details omitted): div class=outline-2 h2Header 1/h2 div class=outline-text-2Some contents/div div class=outline-3 h3Header 1.1/h3 div class=outline-text-3Contents 1.1/div /div div class=outline-3 h3Header 1.2/h3 div class=outline-text-3Contents 1.2/div /div /div There is a wrapper around each subtree, but within it things are a little too linear for what I want to do: it would be very useful to have a div containing the contents of each subtree, everything except the title, in addition to what there already is (so that one could hide it, unfold it on click to show the headers below, and so on). Something like this maybe: div class=outline-2 h2Header 1/h2 div class=contents-2 div class=outline-text-2Some contents/div div class=outline-3 h3Header 1.1/h3 div class=outline-text-3Contents 1.1/div /div div class=outline-3 h3Header 1.2/h3 div class=outline-text-3Contents 1.2/div /div /div /div Is that doable ? If so, how can I do it ? Is that a good idea ? I _can_ exploit jQuery with the current structure to hide/show all the children of a div.outline-2 that are not an h2, and that is my backup plan. I can also probably add the div I want by manipulating the DOM in jQuery but it sounds very sub-optimal. So I wanted to ask here for advice first ... What do you think ? Thanks for your help ! /vincent
[Orgmode] Re: Coding systems in Babel
Hello, So, the instance of python spawned by C-c C-c receives the text as latin-1 encoded. Somewhere a conversion from UTF8 to latin-1 happens. But I don't want that, I want everything to stay in UTF8 from the beginning to the end. I guess I have two questions: At what point in the process is the convertion performed ? How do I prevent it / how do I specify UTF8 as the exchange format between Org-Babel and outside processes spawned by C-c C-c ? Mmmmkay, answering to myself (you never know, maybe it will be useful to someone else later ...): the answer to that is in the general interprocess comunication in Emacs.

Hi, (and it would be excellent to allow for a code block as a preamble, instead of a string in the header or as an alternative, because preambles once they are allowed tend to grow uncontrollably ;-) This is currently possible using the `sbe' function. Arbitrary emacs lisp can be placed inside of header arguments, and the `sbe' take the name of a code block and returns its result. Very cool ! That does all I want, thanks for the info. For multi-line it is a bit heavy to write, with lots of \n and preamble .= lskjd, but I can live with that. Unless there is a way already to write something like this ? --8---cut here---start-8--- #+source: my-preamble #+begin_src python :return preamble # -*- coding: utf-8 -*- import os,sys,whatever #+end_src #+begin_src python :preamble (org-babel-get-and-expand-source-code-body my-preamble) :return s s = é #+end_src --8---cut here---end---8--- There is org-babel-get-src-block-info but it looks at the block around (point), not by name ... so I guess it would not be too hard to write the extraction method, but it might be somewhere in the code already. One naive question : why is the code path different for tangling and evaluation ? One would think that a natural way for evaluation would be to tangle the current block (plus included noweb stuff etc) into a temporary file and eval that file ... and that would enable shebang for evaluation as well. There must be something I am missing here. Tangling works for *any* programming language, even those which have yet to be created and have no explicit Emacs or Org-mode support, this is because on tangling the code block is simply treated as text. As far as I understood from testing, tangling does adapt to the language (at least to implement :var in a suitable way), so I was under the impression that evaluating could be implemented as some kind of wrapping around the tangled output - and obviously the wrapping would have to be language-specific even if for the most part the tanglong is not. I am just discovering all of this, sorry if I have horrible misconceptions about the thing ... Regards, /v ___ Emacs-orgmode mailing list Please use `Reply All' to send replies to the list.

[Orgmode] Re: Babel, Python and UTF-8
#+begin_src python # -*- coding: utf-8 -*- s = é #+end_src I'm not sure to understand your problem. In fact, the problem is not about inserting a prefix to the block, it's about the coding system itself, I guess. Your é in your Org buffer, how is it encoded? Is your Org buffer an UTF-8 one, or a Latin-1? Doesn't really matter, in fact ... Whenever a python file contains a non-ascii character (utf-8 or latin-1) it insists on finding an indication of the encoding within the file. If latin-1, it finds \xe9, if utf-8, it finds \xc3, but in both cases it raises this: # SyntaxError: Non-ASCII character '\xe9' in file /Users/vincent/toto.py # on line 1, but no encoding declared; see # http://www.python.org/peps/pep-0263.html for details That's even if the character in question lies within a string. That makes a lot of sense in terms of portability, but it makes on-the-fly evaluation a bit more complicated. In the second, you want an ISO Latin 1 block of text to be tangled or executed as UTF-8. Is this right? No, I want everything in utf-8, there is no converting to do anywhere, just telling python that it is utf-8. Isn't such a prefix already available through the shebang option: can't it be multiline? Anyway, I don't think it's the problem here... Hmm, didn't know about :shebang, but it seems to be ignored (at least for python) because this works without a syntax error: --8---cut here---start-8--- #+begin_src python :shebang sldfkj return 1 #+end_src --8---cut here---end---8--- Anyway, :prefix cannot hurt I guess ... /v ___ Emacs-orgmode mailing list Please use `Reply All' to send replies to the list.

[Orgmode] Re: Babel, Python and UTF-8
Hi, I've just pushed up a new prefix header argument. Fantastic ! It works exactly as needed. Thanks a lot ! This header argument only has meaning for python code blocks (since it is tied into evaluation each language would have to handle it separately). That's fine, most cases can probably be handled using something like prefix anyway. It is just Python insisting to find the coding instruction in the first 2 lines that causes trouble, so a specific implementation makes sense.

[Orgmode] Babel, Python and UTF-8
Hi, I am discovering org-mode and org-babel, and wanted to try it out with python code blocks. My use case would involve text processing, encoded as UTF-8. Usually a python file has to contain a line to that effect, saying sth like # -*- coding: utf-8 -*-(without which an error is raised). Is there a way to manage that during org-babel block evaluation ? Thanks for your help ! /v ___ Emacs-orgmode mailing list Please use `Reply All' to send replies to the list.

[Orgmode] Re: Babel, Python and UTF-8
Hi, I would suggest just trying it out first and seeing if you get an error without such a line. Well, I do, that's why I'm asking ;-) Also, you could try adding the line to the beginning of your code block. I tried like this : --8---cut here---start-8--- #+begin_src python # -*- coding: utf-8 -*- s = é #+end_src --8---cut here---end---8--- The error message tells me that the error happens on line 4, hence the coding line ends up on line 3, and python only takes it into account if it is one of the first two ... so it almost works, but it doesn't. If there is definitely a problem please reply to this thread and we could easily add a header argument for this case, possibly named :prefix which could be used to specify such a code-block-prefix for code evaluation. This header argument could then be set globally or on the file, heading, or code block level. That would be fantastic ! (And possibly useful in other cases as well ...)
