I did try: #+ATTR_LaTeX: :multicolumn :options [htb] #+BEGIN_figure ... #+END_figure ... and :multicolumn had no effect on the output LaTeX code (either with or without the preceding ":" -- I tried both): \begin{figure}[htb] \lstset{language={},label=code1,caption={Some code},numbers=none} \begin{lstlisting} // SuperCollider code here . \end{lstlisting} \end{figure} Nor does this make a difference: #+ATTR_LaTeX: :float multicolumn :options [htb] #+BEGIN_figure And if I omit BEGIN_figure altogether, and try to apply :float directly to the source code block, then the floating environment doesn't appear in the LaTeX code at all. The other reference to multicolumn is for table export, and this isn't a table either. So I think, as currently designed, :multicolumn simply doesn't apply. I'm aware that BEGIN_figure delimits a "special block" which translates into LaTeX as an arbitrary environment, and not all environments can be floated safely... but perhaps one approach for the future would be to consider BEGIN_figure to be an extra-special "special block" where we know that the properties of LaTeX floating bodies are valid. Or relax the restriction so that BEGIN_figure* no longer tries to treat _ as a subscript marker. hjh

I.e., why don't you apply caption to src block? You can tweak the position of the caption with "captionpos" option in listings environment. Caption are not supported in special blocks because these could contain more than one object, and it wouldn't be clear which of them would have the caption. > 2.

BEGIN_figure is a "special block", i.e. a generic environment. "[htb]" does not always make sense in every environment. Also, figure environment is created automatically in some cases (e.g., when `org-latex-listings' is nil and source block is captioned), so you generally don't need to write it explicitly. Anyway, you can easily add "[htb]" options to all figure environments in the output with a filter. Regards, -- Nicolas Goaziou
[O] Exporting source code blocks as LaTeX figures
Couple of questions about exporting LaTeX figures that are neither tables nor images -- specifically, source code blocks using the listings package. 1. Is there any way to use #+CAPTION with a #+BEGIN_figure block, so that the caption will be rendered underneath the text in the figure? It seems (from reading the org manual and some experimentation on my own) that the answer is no. That's rather inconvenient; the journal specifies that captions should appear below their respective figures, but as it is: #+CAPTION: Some code #+NAME: code1 #+BEGIN_figure #+BEGIN_SRC {} // blah blah --> \begin{figure} \caption{\label{code1}Some code} \lstset{language={},numbers=none} \begin{lstlisting} // blah blah --> Figure 1. Some code. // blah blah . I can work around it by not using #+CAPTION, and writing \caption{...}\label{...}. That shouldn't be a problem for this project, unless for some reason I should have to re-export as, say, ODT or HTML. 2. Is the customize variable "Org Latex Default Figure Position" only used for tables and images? It would be nice if it applied to BEGIN_figure as well (unless :options override that). "#+ATTR_LaTeX: :options [htb]" is a mite inconvenient to replicate for every code example. Certainly possible, but it would save a little effort if the default were used here too. hjh
