Wrap latex commands

[ratnanil]

As stated in #13, I want to use the latex-environment filter to highlight specific parts of my code, using the listings latex package / environment together with colorbox. Per default, all latex code within a listings environment is ignored. However, I can specify an escape character in the package options (see here)

escapechar=⟨character⟩ or escapechar={}
If not empty the given character escapes the user to LATEX: all code between
two such characters is interpreted as LATEX code

So if I set the escapechar = |, everything in between | in my listing environment will be interpreted as latex code. Is there a way to get this input:

:::{.lstlisting}
[one]{.colorbox optons = "gray"}, [two]{.colorbox options = "red"}
:::

to this latex output (note the wrapping |)?:

\begin{lstlisting}
|\colorbox{gray}{one}|, |\colorbox{red}{two}|
\end{lstlisting}
