[Orgmode] Re: Org-special-blocks for code chunks
Hi Chris, Chris Gray wrote: Sébastien Vauban wrote: I have a problem exporting code chunks to LaTeX (beamer, in fact -- but that does not change anything to the problem) that contain underscores. I can't get a properly outputted underscore in my slide. Any idea or workaround? Is lstlisting like a verbatim environment? Yes, it is. What's extra is the highlight of keywords, contextual for every programming language. I think you might be able to just use \begin{lstlisting} and \end{lstlisting} in that case. Org does not interpret anything inside such blocks, which is why org-special-blocks was created in the first place. OK. That works. Though, I'm lost about choosing the best representation for code chunks (I don't even speak here of literate programming) to be shown in slides or documents. Look, I've done an ECM with the different ways I currently see for Org-mode: --8---cut here---start-8--- * Org *** A. To escape the \_ * 1.

[Orgmode] Re: Org-special-blocks for code chunks
Hi Seb, Thanks for testing things so extensively. Look, I've done an ECM with the different ways I currently see for Org-mode: I've never seen the term ECM before. What does it mean? Conclusions? - Org-special-blocks seems to misbehave in cases A3/B3 (adding an unsound environment) and A4 (letting the underscore being converted); I would argue that it is only misbehaving in A3 and B3, since the whole point of org-special-blocks is that org-style interpretation of your text is happening inside the blocks. In this sense, it was never really meant to be used with verbatim-type environments. (I use it mainly for things like lemma and proof environments). I think that A3/B3 show a bug, though, so that should be fixed. (Either with a special case in org-special-blocks or by moving the hook around in org-exp-latex). I will try to have a look at this later. - Though, case A1 is not very friendly: nothing tells I'm inline LaTeX code (what about other exports, as HTML and the like?) I'm not sure, but I think it sends the whole thing to latex and then renders the output as an image.
