[Orgmode] org-babel: [PATCH] allow emacs-lisp results to be pretty-printed
Hey there, on irc (#org-mode) someone asked how one would go about to insert the result of a emacs-lisp function without it being transformed into a org-mode table. I didn't see any other way, so I wrote a small patch that allows the parameter :results to accept 'pp'. Is this the right way? And where should this special parameter be documented? diff --git a/contrib/babel/lisp/langs/org-babel-emacs-lisp.el b/contrib/babel/lisp/langs/org-babel-emacs-lisp.el index 39f5cc7..60671ac 100644 --- a/contrib/babel/lisp/langs/org-babel-emacs-lisp.el +++ b/contrib/babel/lisp/langs/org-babel-emacs-lisp.el @@ -39,10 +39,14 @@ "Execute a block of emacs-lisp code with org-babel.

OK, I have now modified image placement in LaTeX.
1. Image in text
[[./img/x.png]]
2. Floating image with caption and modified size and placement
#+CAPTION: My caption
#+ATTR_LATEX: placement=[H] width=0.6\textwidth
[[./img/x.png]]
3. Wrapping text around the image
#+ATTR_LaTeX: wrap
#+ATTR_HTML: align="left"
[[./img/x.png]]
4. Wrapping text around the image with modified size and wrapfigure
placement
#+ATTR_LaTeX: wrap width=0.38\textwidth placement={r}{0.4\textwidth
#+ATTR_HTML: align="right" width="250"
[[./img/x.png]]
Even if there is a caption, wrap will work and force the
image to be non-floating with text wrapped around.
Comments?

P.S. if you have customized org-export-latex-classes, you might have
to undo, then redo this customization, or add the float and wrapfigure
environments by hand
to all classes you want to use.

I assumed it would appear untimed in the 2009-09-30 agenda and possibly 9:00-10:00 in the 2009-10-01 agenda. Reading the documentation I kind of guess why this happens: In the headline of the entry itself, a time(range) may also appear as plain text (like ‘12:45’ or a ‘8:30-1pm’). But it's surprising that the time of day of the timestamp in the headline is connected to the scheduled date. I also tried this: * TODO Confirm meeting with Alice tomorrow at 09:00-10:00 SCHEDULED: <2009-09-30 Wed> In this case I still get the entry in the time grid for 2009-09-30 but nothing on 2009-10-01.

Re: [Orgmode] newline at start of buffer
Hi Dan, this was a stupid hack to get the headline away from the first buffer line which can cause problems in Org under some circumstances which are hard to consistently remove. It looks a the empty buffer case because this is what will happen when people open a new buffer and immediately create a headline in this way. When there is already something in the buffer, even a space, I am assuming the user wants to be in control. If it is not bothering you a lot, I'd like to keep it this way. - Carsten On Oct 3, 2009, at 5:33 AM, Dan Davison wrote: In a completely empty buffer, org-insert-heading inserts a newline before the first heading. However, if there is (e.g.) a single space character in the buffer (after point), the heading goes on the first line.

[Orgmode] Problems using org-babel
I enabled org-babel according to the instructions on worg, but am running into a number of issues which I am guessing are a function of my configuration. For example, enabling org-babel completely breaks remember mode, giving me a "wrong ..." argument (sorry - don't have it in front of me) error. Adding a python source block still allows exporting, but adding a ruby block causes a "wrong..." error as well when I try to export. I guess the real question is how do I debug this? I am relatively new to emacs, and not familiar really with how to track some of these issues down.

(The load path, require the org and org-babel). That way you can guarantee the problem is with org-mode/org-babel and not with some other part of your setup. emacs -Q -l newfile.el If you've done so, incrementally add parts of your old init.el to the new file and see if something breaks. That way you find the step that doesn't work. If you experience problems with the initial step of getting org-mode to run with an empty init.el file, tell us what versions you're using (M-x org-version RET) and what exactly you did to cause the error message. (Alternatively you could also do M-x toggle-debug-on-error RET and post that.) br, benny ___ Emacs-orgmode mailing list Remember: use `Reply All' to send replies to the list.

Hi Keith,
In general, a good approach is to replace your personal configuration
file with an absolutely bare-bones file -- which only contains the
"official" recommended configuration for org-mode and
org-babel:
http://orgmode.org/manual/Installation.html#Installation
http://orgmode.org/manual/Activation.html#Activation
http://orgmode.org/worg/org-contrib/babel/org-babel.php#getting-started
Presumably you have installed org-mode yourself, rather than using the
version that comes with emacs (otherwise you would not have org-babel),
so minimally that would be something like this:
--8<---cut here---start->8---
(add-to-list 'load-path "/your/location/of/org-mode/lisp")
(require 'org-install)
(add-to-list 'auto-mode-alist '("\\.org\\'" . org-mode))
(global-set-key "\C-cl" 'org-store-link)
(global-set-key "\C-ca" 'org-agenda)
(global-set-key "\C-cb" 'org-iswitchb)
(add-to-list 'load-path "/your/location/of/org-mode/contrib/lisp")
(require 'org-babel-init)
(require 'org-babel-ruby) ;; requires ruby, irb, ruby-mode, and inf-ruby
(require 'org-babel-python);; requires python, and python-mode
--8<---cut here---end--->8---
With a configuration like this, org-babel should not interact badly with
remember mode. So if you're still seeing this problem, please report
back, telling us *exactly* what steps you did, in addition to operating
system, org-mode version, emacs version. Error messages in emacs tend to
get copied to a buffer called *Messages*, so that's a convenient place
to retrieve the exact error message from -- perhaps you could send the
last few lines from there. If you don't see the problem then you can add
your personal config back in incrementally until something breaks.
For the problem with ruby, could you send a minimal file containing a
ruby block with which you have a problem? Have you definitely got the
various ruby dependencies installed (ruby, irb, inf-ruby.el,
ruby-mode.el). What operating system and version of org?
