Some => ligature doesn't work with Scala

[limansky]

Hi,

I've found that => doesn't replaced with ligature for Scala code in lstlisting. E.g.

\documentclass{article}
\usepackage{fontspec}
\setmonofont{FiraCode-Regular.otf}[
  BoldFont=FiraCode-Bold.otf,
  Contextuals=Alternate% Activate the calt feature
]

\usepackage{xcolor}
\usepackage{listings}
\usepackage[verbatim]{lstfiracode}% Activate ligatures in verbatim

\lstset{
  language=scala,
  style=FiraCodeStyle,% Use predefined FiraCodeStyle
  basicstyle=\ttfamily,% Use \ttfamily for source code listings
  commentstyle=\color{orange}
}

\begin{document}

\begin{lstlisting}
object Main extends App {

  println("Hello world")

  def foo(lst: List[String]) = {
    lst.sortBy((a, b) => a >= b)
  }
}

\end{lstlisting}
\end{document}

I suppose it's because => is defined as keyword in lstlisting for Scala

@limansky You are probably right. I will need to figure out something to override the language=scala setting.

I wish it still would have a color and font weight defined for keywords, but printed as a ligature.
