\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{JetBrainsMono} fonts, and (if needed) \textit{remove} ligature's features, in order to use (in fact) \texttt{JetBrainsMonoNL} fonts. Following \textsf{OpenType} fonts are supported :

\begin{lstlisting}[language={[latex]TeX},basicstyle=\footnotesize\ttfamily,commentstyle=\itshape\color{gray},keywordstyle=\color{magenta},tabsize=4,frame=single]
JetBrainsMono-Bold.otf						JetBrainsMono-BoldItalic.otf
JetBrainsMono-ExtraBold.otf					JetBrainsMono-ExtraBoldItalic.otf
JetBrainsMono-ExtraLight.otf				JetBrainsMono-ExtraLightItalic.otf
JetBrainsMono-Italic.otf					JetBrainsMono-Light.otf
JetBrainsMono-LightItalic.otf				JetBrainsMono-Medium.otf
JetBrainsMono-MediumItalic.otf				JetBrainsMono-Regular.otf
JetBrainsMono-SemiBold.otf					JetBrainsMono-SemiBoldItalic.otf
JetBrainsMono-Thin.otf						JetBrainsMono-ThinItalic.otf
\end{lstlisting}

Two version of config/macro are available :

\begin{tabular}{l}
	~~~\lstinline[language={[latex]TeX},basicstyle=\ttfamily]|jetbrainsmono(-xxxx)| or \lstinline[language={[latex]TeX},basicstyle=\ttfamily]|jetbrainscode(-xxxx)|
	\\
	~~~\lstinline[language={[latex]TeX},basicstyle=\ttfamily]|\jetbrainsmono(xxxx)| or \lstinline[language={[latex]TeX},basicstyle=\ttfamily]|\jetbrainscode(xxxx)| \\
\end{tabular}

\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[jetbrainsmono]           % or jetbrainscode
{Extension=.otf,
    UprightFont=JetBrainsMono-Regular,
    ItalicFont=JetBrainsMono-Italic,
    BoldFont=JetBrainsMono-Bold,
    BoldItalicFont=JetBrainsMono-BoldItalic,
    Contextuals=AlternateOff                   %for mono version
}
\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[jetbrainsmono-medium]     % or jetbrainscode-medium
    {Extension=.otf,
    UprightFont=JetBrainsMono-Medium,
    ItalicFont=JetBrainsMono-MediumItalic,
    BoldFont=JetBrainsMono-ExtraBold,
    BoldItalicFont=JetBrainsMono-ExtraBoldItalic,
    Contextuals=AlternateOff                   %for mono version
}
\end{lstlisting}

\begin{lstlisting}[language={[latex]TeX},basicstyle=\footnotesize\ttfamily,commentstyle=\itshape\color{gray},keywordstyle=\color{magenta},tabsize=4,frame=single]
\defaultfontfeatures[jetbrainsmono-light]      % or jetbrainscode-light
    {Extension=.otf,
    UprightFont=JetBrainsMono-Light,
    ItalicFont=JetBrainsMono-LightItalic,
    BoldFont=JetBrainsMono-SemiBold,
    BoldItalicFont=JetBrainsMono-SemiBoldItalic,
    Contextuals=AlternateOff                   %for mono version
}
\end{lstlisting}

\begin{lstlisting}[language={[latex]TeX},basicstyle=\footnotesize\ttfamily,commentstyle=\itshape\color{gray},keywordstyle=\color{magenta},tabsize=4,frame=single]
\defaultfontfeatures[jetbrainsmono-extralight] % or jetbrainscode-extralight
    {Extension=.otf,
    UprightFont=JetBrainsMono-ExtraLight,
    ItalicFont=JetBrainsMono-ExtraLightItalic,
    BoldFont=JetBrainsMono-Medium,
    BoldItalicFont=JetBrainsMono-MediumItalic,
    Contextuals=AlternateOff                   %for mono version
}
\end{lstlisting}

\begin{lstlisting}[language={[latex]TeX},basicstyle=\footnotesize\ttfamily,commentstyle=\itshape\color{gray},keywordstyle=\color{magenta},tabsize=4,frame=single]
\defaultfontfeatures[jetbrainsmono-thin]       % or jetbrainscode-thin
    {Extension=.otf,
    UprightFont=JetBrainsMono-Thin,
    ItalicFont=JetBrainsMono-ThinItalic,
    BoldFont=JetBrainsMono-Regular,
    BoldItalicFont=JetBrainsMono-Italic,
    Contextuals=AlternateOff                   %for mono version
}
\end{lstlisting}

\subsection{With config files}

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

\begin{lstlisting}[language={[latex]TeX},basicstyle=\footnotesize\ttfamily,commentstyle=\itshape\color{gray},keywordstyle=\color{magenta},tabsize=4,frame=single]
\usepackage{fontspec}
\setmonofont{jetbrainsmono}[options]               %version regular
\setmonofont{jetbrainsmono-medium}[options]        %version semilight
\setmonofont{jetbrainsmono-light}[options]         %version light
\setmonofont{jetbrainsmono-extralight}[options]    %version extralight
\setmonofont{jetbrainsmono-thin}[options]          %version thin
\end{lstlisting}

\subsection{With the package loading}

With \lstinline[language={[latex]TeX},basicstyle=\ttfamily]|\usepackage[scale=...]{jetbrainsmono-oft}|, \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]
\newfontfamily\jetbrainsmono{jetbrainsmono}
\newfontfamily\jetbrainsmonomedium{jetbrainsmono-medium}
\newfontfamily\jetbrainsmonolight{jetbrainsmono-light}
\newfontfamily\jetbrainsmonoextralight{jetbrainsmono-extralight}
\newfontfamily\jetbrainsmonothin{jetbrainsmono-thin}
\end{lstlisting}

\section{Algorithm code, with ligatures}
