texで現在のページ/総ページ表記をさせたい

概要

【2022年6月22日 追記】
この記事は慶應義塾大学SFCの大学院受験に際して, 研究計画書をtexで書かないと死んでしまう奇特な人に向けたものです. 素直にWordで書いた方が楽だと思います.
【追記終わり】

院の研究計画書(14ページ参照)現在のページ数/総ページ数てな感じのフォーマットを指定されてた.
苦労したのでメモ.

環境

  • Pop!_OS 20.10
  • texlive 2020

texファイルの編集

プリアンブルに \usepackage{myfancyhdr}\usepackage{lastpage}, \pagestyle{fancy}, \cfoot{\thepage{}/{}\pageref{LastPage}}を追加する.
こんな感じ.

\documentclass[a4j,10pt, twocolumn]{jarticle}
\usepackage[dvipdfmx]{graphicx}
\usepackage{myfancyhdr}
\usepackage{amssymb}
% \usepackage{amsmath}
\usepackage{float}
\usepackage{usebib}
\bibinput{refs}
\usepackage{lastpage}
% \usepackage{slashbox}
%---------------------------------------------------
% ページの設定
%---------------------------------------------------
\setlength{\textwidth}{170truemm}
\setlength{\textheight}{250truemm}
\setlength{\topmargin}{-14.5truemm}
\setlength{\oddsidemargin}{-5.5truemm}
\pagestyle{fancy}
\cfoot{\thepage{}/{}\pageref{LastPage}}
\setlength{\headheight}{0truemm}
\setlength{\parindent}{1zw}

ちなみに使ったテンプレートはこれです.

styファイルを用意する

自分の環境だと

/usr/share/texlive/texmf-dist/tex/latex/fancyhdr/fancyhdr.sty

に目的のstyファイルがあった.

$kpsewhich fancyhdr.sty

でインストールされてるパスが分かる. こいつをcatしてコピペするなりcpするなりして作業ディレクトリに持っていきmyfancyhdr.styとして保存.

公式リポジトリから落としてきてもいいがバージョンが変わってるはずので適宜読み替えるか, 下に貼ったやつを丸コピしてください.

23行目を

\ProvidesPackage{fancyhdr}%

から

\ProvidesPackage{myfancyhdr}%

に変更する.

次に146-152行目と181行目をコメントアウトする. 181行目はコメントアウトしなくても大丈夫だけど, しなかったらページの上部に謎の横線が入る. 説明ダルいからどんな風になるかはコンパイルして確認してみてください. とりあえずここを消すと単にページ番号の表記が目的通りになる.
