lineno の linenumbers 環境で、古いスタイルの番号から行番号に変更します。

Question

ドキュメントでは古いスタイルの番号を使用していますが、行番号環境 (linenoの\linenumbers環境) では行番号の方が好みです。これを強制するにはどうすればよいでしょうか (別のフォントに変更せずに)?

\documentclass{article}
\usepackage{fontspec,lineno}
    \setmainfont[Numbers=OldStyle]{Linux Libertine O}
    \renewcommand\linenumberfont{\normalfont\scriptsize\rmfamily}

\begin{document}
\begin{linenumbers}
\noindent Continual delighted\linelabel{1stword} as elsewhere am convinced unfeeling. Introduced stimulated attachment no by projection. To loud lady whom my mile sold four. Need miss all four case fine age tell. He families my pleasant speaking it bringing\linelabel{2ndword} it thoughts. View busy dine oh in knew if even. Boy these along far own other equal old fanny charm. Difficulty invitation put introduced\linelabel{3rdword} see middletons nor preference.
\end{linenumbers}
\vspace{\baselineskip}
\noindent I like the words I find in line \lineref{1stword}, \lineref{2ndword}, and \lineref{3rdword}.
\end{document}

Answer 1

数字だけを変更するには、fontspecコマンドを使用します\addfontfeatures{Numbers={Lining, Monospaced}}（fontspecマニュアル）。( を指定する必要もないかもしれませんMonospacedが、指定しても問題はありません。)\normalfontおよび\rmfamilyも必要ありません。

\documentclass{article}
\usepackage{fontspec,lineno}
    \setmainfont[Numbers=OldStyle]{Linux Libertine O}
    \renewcommand{\linenumberfont}{\scriptsize\addfontfeatures{Numbers={Lining, Monospaced}}}

\begin{document}
\begin{linenumbers}
\noindent Continual delighted\linelabel{1stword} as elsewhere am convinced unfeeling.

Answer 2

Type 1 フォント (pdflatex) ユーザーの場合は、次のようにします。

\documentclass{article}
\usepackage[osf]{libertine}
\usepackage[T1]{fontenc}
\usepackage{lineno}

\renewcommand\linenumberfont{\fontfamily{LinuxLibertineT-TLF}\scriptsize\selectfont}

\begin{document}
\begin{linenumbers}
\noindent Continual delighted\linelabel{1stword} as elsewhere am convinced unfeeling. Introduced stimulated attachment no by projection. To loud lady whom my mile sold four. Need miss all four case fine age tell. He families my pleasant speaking it bringing\linelabel{2ndword} it thoughts. View busy dine oh in knew if even. Boy these along far own other equal old fanny charm. Difficulty invitation put introduced\linelabel{3rdword} see middletons nor preference.
\end{linenumbers}
