\section{Usages}

With \lstinline[language={[latex]TeX},basicstyle=\ttfamily]|\usepackage{fontspec}| (so with \lstinline[language={[latex]TeX},basicstyle=\ttfamily]|XeTeX| or \lstinline[language={[latex]TeX},basicstyle=\ttfamily]|LuaLaTeX| compilation), you can use \texttt{CascadiaCode} fonts, and \textit{remove} ligature's features, in order to use (in fact) \texttt{CascadiaMono} fonts.

\smallskip

Following OpenType fonts are supported (it's based on \texttt{CascadiaCode} without the ligatures) :

\begin{lstlisting}[language={[latex]TeX},basicstyle=\footnotesize\ttfamily,commentstyle=\itshape\color{gray},keywordstyle=\color{magenta},tabsize=4,frame=single]
CascadiaCode-Bold.otf                      CascadiaCode-BoldItalic.otf
CascadiaCode-ExtraLight.otf                CascadiaCode-ExtraLightItalic.otf
CascadiaCode-Italic.otf                    CascadiaCode-Light.otf
CascadiaCode-LightItalic.otf               CascadiaCode-Regular.otf
CascadiaCode-SemiBold.otf                  CascadiaCode-SemiBoldItalic.otf
CascadiaCode-SemiLight.otf                 CascadiaCode-SemiLightItalic.otf
\end{lstlisting}

\section{The default settings}

The \texttt{fontspec} config for the \textit{normal} version :

\begin{lstlisting}[language={[latex]TeX},basicstyle=\footnotesize\ttfamily,commentstyle=\itshape\color{gray},keywordstyle=\color{magenta},tabsize=4,frame=single]
\defaultfontfeatures[CascadiaMono]
    {Extension=.otf,
    UprightFont=CascadiaCode-Regular,
    ItalicFont=CascadiaCode-Italic,
    BoldFont=CascadiaCode-Bold,
    BoldItalicFont=CascadiaCode-BoldItalic,
    Contextuals=AlternateOff}
\end{lstlisting}

The \texttt{fontspec} config for the other versions are :

\begin{lstlisting}[language={[latex]TeX},basicstyle=\footnotesize\ttfamily,commentstyle=\itshape\color{gray},keywordstyle=\color{magenta},tabsize=4,frame=single]
\defaultfontfeatures[CascadiaMono-Light]
    {Extension=.otf,
    UprightFont=CascadiaCode-Light,
    ItalicFont=CascadiaCode-LightItalic,
    BoldFont=CascadiaCode-Regular,
    BoldItalicFont=CascadiaCode-Italic,
    Contextuals=AlternateOff}
\end{lstlisting}

\begin{lstlisting}[language={[latex]TeX},basicstyle=\footnotesize\ttfamily,commentstyle=\itshape\color{gray},keywordstyle=\color{magenta},tabsize=4,frame=single]
\defaultfontfeatures[CascadiaMono-SemiLight]
    {Extension=.otf,
    UprightFont=CascadiaCode-SemiLight,
    ItalicFont=CascadiaCode-SemiLightItalic,
    BoldFont=CascadiaCode-SemiBold,
    BoldItalicFont=CascadiaCode-SemiBoldItalic,
    Contextuals=AlternateOff}
\end{lstlisting}

\begin{lstlisting}[language={[latex]TeX},basicstyle=\footnotesize\ttfamily,commentstyle=\itshape\color{gray},keywordstyle=\color{magenta},tabsize=4,frame=single]
\defaultfontfeatures[CascadiaMono-ExtraLight]
    {Extension=.otf,
    UprightFont=CascadiaCode-ExtraLight,
    ItalicFont=CascadiaCode-ExtraLightItalic,
    BoldFont=CascadiaCode-SemiLight,
    BoldItalicFont=CascadiaCode-SemiLightItalic,
    Contextuals=AlternateOff}
\end{lstlisting}

It's possible to use ligatures with \texttt{Code} alias, instead of \texttt{Mono}.

\pagebreak

\subsection{With config files}

The idea is to propose \texttt{fontspec} config files to load correctly \texttt{CascadiaMono} features.

\begin{lstlisting}[language={[latex]TeX},basicstyle=\footnotesize\ttfamily,commentstyle=\itshape\color{gray},keywordstyle=\color{magenta},tabsize=4,frame=single]
\usepackage{fontspec}
%w/o ligatures
\setmonofont{CascadiaMono}[options]                %version regular
\setmonofont{CascadiaMono-SemiLight}[options]      %version semilight
\setmonofont{CascadiaMono-Light}[options]          %version light
\setmonofont{CascadiaMono-ExtraLight}[options]     %version extralight
%w ligatures
\setmonofont{cascadiacode}[options]                %version regular
\setmonofont{cascadiacode-semilight}[options]      %version semilight
\setmonofont{cascadiacode-light}[options]          %version light
\setmonofont{cascadiacode-extralight}[options]     %version extralight
\end{lstlisting}

\subsection{With the package loading}

With \lstinline[language={[latex]TeX},basicstyle=\ttfamily]|\usepackage[scale=...]{cascadiamono-otf}|, \lstinline[language={[latex]TeX},basicstyle=\ttfamily]|fontspec| is loaded, and \lstinline[language={[latex]TeX},basicstyle=\ttfamily]|fontfamily| are defined :

\begin{lstlisting}[language={[latex]TeX},basicstyle=\footnotesize\ttfamily,commentstyle=\itshape\color{gray},keywordstyle=\color{magenta},tabsize=4,frame=single]
%w/o ligatures
\newfontfamily\cascadiamono{CascadiaMono}
\newfontfamily\cascadiamonosemilight{CascadiaMono-SemiLight}
\newfontfamily\cascadiamonolight{CascadiaMono-Light}
\newfontfamily\cascadiamonoextralight{CascadiaMono-ExtraLight}
%w ligatures
