Including non-R code and getting a reference about thesisdown HOT 6 CLOSED

I think I would try using a different engine for the chunks you are referring to in different languages: http://rmarkdown.rstudio.com/authoring_knitr_engines.html

Thank you for your quick answer. I might have poorly expressed my problem and what I wanted to achieve. I do not want to run the code, just display it with syntax highlighting. That's why eval = FALSE. But thank you for pointing out the bash engine. I'll use that. My problem is: When I use the code above, I see the script file in the PDF output as I want to, but it does not get a caption. It basically looks like that

The TeX output created by it looks like that

\begin{Shaded}
\begin{Highlighting}[]
\KeywordTok{for} \ExtensionTok{foo}\NormalTok{ in (ls bar)}
\KeywordTok{do}
  \BuiltInTok{echo} \VariableTok{$foo}
\KeywordTok{done}
\end{Highlighting}
\end{Shaded}

For example, when I use include_graphics - I am aware that this is an R function that creates the figure -
in an R script

```{r img, results="asis", echo=TRUE, fig.cap="A figure", out.width='\\textwidth'}
include_graphics("./figure/afigure.png")
```

the TeX output looks like that

\begin{Shaded}
\begin{Highlighting}[]
\KeywordTok{include_graphics}\NormalTok{(}\StringTok{"./figure/afigure.png"}\NormalTok{)}
\end{Highlighting}
\end{Shaded}

\begin{figure}
\includegraphics[width=\textwidth]{./figure/afigure} \caption{A figure}\label{fig:img}
\end{figure}

What I basically want to achieve is to get a \begin{figure} .. \end{figure} with a label etc around the \begin{shaded} .. \end{shaded} part. I thought that this is not an uncommon problem and as I could not find anything on Google I was asking here. The solutions I see at that point are

1. Creating an image by hand and including it with include_graphics(). I don't really like that solution as that is error prone especially when the code changes.
2. I could probably use a knitr hook and making a new option echo.asfig. When this is set, I create the needed TeX before and after the echoed output. Probably the easiest to implement.
3. I could write an R function like "highlight(sourcefile)" that renders the code (using a tool like prism or highlight) and then includes the figure using \include_graphics. That is probably the solution that takes the most effort to implement and creates dependencies to other (platform dependent) tools - prism for example is written in JavaScript and would need nodeJs to run.

Do you have any suggestions on what other options I may have, or have I just overlooked on how to do it in Rmd?

Ah, thanks for clarifying. I didn't quite understand. I think your best bet here is a knitr hook. Here is a related example, though it is using the old Rnw format: https://github.com/yihui/knitr-examples/blob/master/074-example-environment.Rnw

Thank you. I'll think about it and try around a bit over the next couple of weeks. If I have a solution are you interested in a pull request?

Yes, please!
