This page is intended for those who wish to use the Fira Code fonts in the LaTeX output files. If you wish to use Fira Code to display your LaTeX source files, then please check whether your LaTeX editor supports Fira Code or not.
Activate ligatures in lstlisting
The lstfiracode package defines FiraCodeStyle for the use with the listings package. Here is a sample LaTeX document:
% !TeX program = XeLaTeX or LuaLaTeX
% !TeX encoding = UTF-8 Unicode
\documentclass{article}
\usepackage{fontspec}
\setmonofont{Fira Code}[
Contextuals=Alternate % Activate the calt feature
]
\usepackage{listings}
\usepackage{lstfiracode} % https://ctan.org/pkg/lstfiracode
\lstset{
language=C++,
style=FiraCodeStyle, % Use predefined FiraCodeStyle
basicstyle=\ttfamily % Use \ttfamily for source code listings
}
\begin{document}
\begin{lstlisting}
/* A simple C++ program */
int main() {
cout << "Hello World"; // prints Hello World
return 0;
}
\end{lstlisting}
\end{document}
Activate ligatures in verbatim
The lstfiracode package also supports the verbatim environment. Here is a sample LaTeX document:
% !TeX program = XeLaTeX or LuaLaTeX
% !TeX encoding = UTF-8 Unicode
\documentclass{article}
\usepackage{fontspec}
\setmonofont{Fira Code}[
Contextuals=Alternate % Activate the calt feature
]
\usepackage{listings}
\usepackage{lstfiracode} % https://ctan.org/pkg/lstfiracode
\begin{document}
\ActivateVerbatimLigatures
\begin{verbatim}
A<-www>>=B
\end{verbatim}
\end{document}
If you do not wish to load the lstfiracode package, here is another solution:
% !TeX program = XeLaTeX or LuaLaTeX
% !TeX encoding = UTF-8 Unicode
\documentclass{article}
\usepackage{fontspec}
\setmonofont{Fira Code}[
Contextuals=Alternate % Activate the calt feature
]
\makeatletter
\renewcommand*\verbatim@nolig@list{} % Empty the no-ligature list
\makeatother
\begin{document}
\begin{verbatim}
A<-www>>=B
\end{verbatim}
\end{document}
