CodeEmphasisLine called on every word in a line instead of the whole line #9
Description
Here is my input file, example.md, only a slight variation on doc example from the docs:
---
header-includes:
- \usepackage{listings}
- \lstset{basicstyle=\ttfamily}
- \newcommand{\CodeEmphasis}[1]{\textcolor{red}{\textit{#1}}}
- \newcommand{\CodeEmphasisLine}[1]{\colorbox{yellow}{#1}}
---
# My Slide {.fragile}
```{.haskell emphasize=2:3-2:14,3:3-3:12,4-4}
myFunc = do
one two three
four five six
seven eight nine
ten eleven twelve
```
When I run pandoc --filter pandoc-emphasize-code --to beamer example.md --output example.pdf
Instead of one solid yellow background I get irregularly shaped backgrounds around each word.
When I run pandoc --filter pandoc-emphasize-code --to beamer example.md
I get the following output:
\begin{frame}[fragile]{My Slide}
\protect\hypertarget{my-slide}{}
\begin{lstlisting}[escapechar=£,language=haskell]
myFunc = do
£\CodeEmphasis{one}£ £\CodeEmphasis{two}£ £\CodeEmphasis{thre}£e
£\CodeEmphasis{four}£ £\CodeEmphasis{five}£ six
£\CodeEmphasisLine{seven}£ £\CodeEmphasisLine{eight}£ £\CodeEmphasisLine{nine}£
ten eleven twelve
\end{lstlisting}
\end{frame}
and you can see \CodeEmphasisLine is wrapped around each word in the line, rather than the line itself. This has no consequences the styling is purely on the text (i.e. \textit), but when the styling involves the background color it leads to a PDF with a series of blocks around each word, with white/background-space in between the highlighted words.
