Kotlin for LaTeX Listings Build LaTeX

When I was writing my bachelor thesis using Kotlin and needed to document some code in LaTeX, I realized that the lstpackage does not support Kotlin syntax highlighting by default. So, I decided to create a language template for it.

Example

Check out this example of the default style or download the complete document.

Feel free to add more keywords or define new styles!

How to use it?

First of all, you need to copy the language definition into your LaTeX document:

\usepackage[dvipsnames]{xcolor}
\usepackage{listings}

\lstdefinelanguage{Kotlin}{
  comment=[l]{//},
  commentstyle={\color{gray}\ttfamily},
  emph={filter, first, firstOrNull, forEach, lazy, map, mapNotNull, println},
  emphstyle={\color{OrangeRed}},
  identifierstyle=\color{black},
  keywords={!in, !is, abstract, actual, annotation, as, as?, break, by, catch, class, companion, const, constructor, continue, crossinline, data, delegate, do, dynamic, else, enum, expect, external, false, field, file, final, finally, for, fun, get, if, import, in, infix, init, inline, inner, interface, internal, is, lateinit, noinline, null, object, open, operator, out, override, package, param, private, property, protected, public, receiver, reified, return, return@, sealed, set, setparam, super, suspend, tailrec, this, throw, true, try, typealias, typeof, val, var, vararg, when, where, while},
  keywordstyle={\color{NavyBlue}\bfseries},
  escapeinside={//(`}{`)},
  morecomment=[s]{/*}{*/},
  morestring=[b]",
  morestring=[s]{"""*}{*"""},
  ndkeywords={@Composable, @Preview, @Deprecated, @JvmField, @JvmName, @JvmOverloads, @JvmStatic, @JvmSynthetic, Array, Byte, Double, Float, Int, Integer, Iterable, Long, Runnable, Short, String, Any, Unit, Nothing},
  ndkeywordstyle={\color{BurntOrange}\bfseries},
  sensitive=true,
  stringstyle={\color{ForestGreen}\ttfamily},
}

Then you need to set the language of your listing to Kotlin:

\begin{lstlisting}[caption={Simple code listing.}, label={lst:example1}, language=Kotlin]
// this is a simple code listing:
println("hello kotlin from latex")
\end{lstlisting}

And finally, your listing should look like this:
Simple Example
(The border is not part of the language definition. Check out example.tex for this style.)
