# LaTeX index page range elision [duplicate]

I'm working on a book project using LaTeX and am stuck on a very fine point of style in the index. The publisher wants page ranges in the index to appear in the form 145--52 (rather than 145--152), page range elision. I have no idea how to to get a LaTeX indexing package to do this. At the moment I'm using imakeidx and the project has two indices (Names and Subjects). I've put together a minimal working example. I'd be grateful for any advice,

\documentclass{article}
\usepackage[utf8]{inputenc}

\title{Index elision problem}
\date{July 2019}

\usepackage{imakeidx}

\makeindex[name = person,title=Name Index,columns=2]
\makeindex[name = subject,title=Subject Index,columns=2]

\begin{document}

\maketitle

\index[person]{Mr. T}
\index[subject]{vans}
\clearpage Space \clearpage filler \clearpage Space \clearpage filler \clearpage Space \clearpage filler \clearpage Space \clearpage filler \clearpage Space \clearpage
Mr. T, vans
\index[person]{Mr. T|(}
\index[subject]{vans|(}
\clearpage filler \clearpage Space \clearpage filler \clearpage Space \clearpage filler
Mr. T, vans
\index[person]{Mr. T|)}
\index[subject]{vans|)}

\printindex[person]
\clearpage
\printindex[subject]

\end{document}

• And what should it be for 61--69?? – user187802 Jul 5 '19 at 13:58
• 61—9. Just clip the digits that don’t add new information. 61—75 is fine. – Mathlete of the Year Jul 5 '19 at 13:59
• I think there is already something like this on the site. – egreg Jul 5 '19 at 14:18
• If you find it please let me know. I’ve been looking for a while. – Mathlete of the Year Jul 5 '19 at 14:18
• tex.stackexchange.com/a/463434/4427 But tell your publisher that saving a few characters at the expense of clarity is a bit silly. – egreg Jul 5 '19 at 14:19
