\section{Description}

\textit{Splentinex} is a serif font family designed for body text. This typeface design was originally crated by Frank Pierpont and Fritz Stelzer in 1913 and released by Monotype as \textit{Plantin}. In 2025, Ben Byram-Wigfield created \textit{Splentino}, a new digitization of the \textit{Plantin} design, for inclusion with the music software Dorico.\footnote{\url{https://blog.dorico.com/2025/06/the-splentino-typeface-reviving-plantin-for-musical-scores/}} \textit{Splentinex} is a modified repackaging of \textit{Splentino} for use with \hologo{LaTeX}. 

\section{Features}

The font family currently includes regular, \textit{italic}, \textbf{bold} and \textbf{\textit{bold italic}} fonts. \textsc{Small capitals} are provided for the regular font only. Old-style figures are included for all four fonts.

\section{Usage with OpenType-capable \hologo{TeX} engines}

I recommend using the OpenType versions of \textit{Splentinex} with a modern \hologo{TeX} engine (such as \hologo{LuaTeX} or \hologo{XeTeX}). If you are using \hologo{LuaLaTeX} or \hologo{XeLaTeX}, use \texttt{fontspec} to select the font and the appropriate options, e.g., by adding \texttt{\textbackslash usepackage\{fontspec\}\textbackslash setmainfont\{Splentinex\}} to your preamble. For detailed options, see that package's documentation.

\section{Usage with legacy \hologo{TeX} engines}

If you wish to use the fonts with a legacy \hologo{TeX} engine, Type 1 fonts and the appropriate support files are provided. To set use the Type 1 version of \textit{Splentinex} in \hologo{LaTeX}, use the following command:

\begin{verbatim}
\usepackage{splentinex}
\end{verbatim}

By default, tabular lining figures (0123456789) are used. The package-level options \texttt{tabular} and \texttt{proportional} can be used to switch between tabular ({\addfontfeatures{Numbers=Tabular}0123456789}) and proportional ({\addfontfeatures{Numbers=Proportional}0123456789}) versions of lining figures. Old-style figures ({\addfontfeatures{Numbers=OldStyle}0123456789}) can be set as the default using package option \texttt{oldstyle}.

\section{Copying}

The \textit{Splentinex} fonts have been released under the \textsc{sil} Open Font License, version 1.1; see \texttt{COPYING}.

\section{Source files and development}

Source files for the \textit{Splentinex} fonts are available on GitHub.\footnote{\url{https://github.com/dbenjaminmiller/splentinex}} Suggestions for feature additions are welcome on GitHub (preferred) or via email. The initial (1.0) release of \textit{Splentinex} is essentially equivalent to version 1.1 of \textit{Splentino} (packaged with Dorico 6.1), but future releases of \textit{Splentinex} may contain changes which diverge from \textit{Splentino}.
