8

I am dogmatic, and I believe that 0 is the very zerost number. Naturally, I would like all my counters to start at 0. Page counters, section counters, subsection counters, theorems, definitions -- everything! -- if it counts, it starts at 0.

I know how I can make a section counter start at 0: Getting section numbering to start at 0

But how do I efficiently satisfy my dogma without having to write many \setcounter{<...>}?

    By default, a \newcounter command initalizes any counter with 0. The package totcount does initialize total counters however with -1. If somebody did not make errors in the class/package setup, this should not be a real issue. If there's a proper \newcounter{foo}[bar] statement, the counters on the reset list are set to zero as soon as the driver counter is increased with \stepcounter or \refstepcounter.

    You are wrong, I believe. The page number is zero until you look at the first page, which of course has page number 1.

  • @ChristianHupfer I am having a bit of trouble understanding your comment. The totcount package initializes total counters with -1, and if I understand correctly, the "total counters" are an addition of that package to count up the number of items of a thing? If yes, then what is the relevance/connection of total counters to counters, especially given the original question?

  • @user89: Just in case you're using the totcount package.

  • The page counter starts at -1 because I set it to the list explicitly.

  • What is this arcane magic? It works with page numbers too! It works with figures! It works with amsmath and amsthm things!

    @user89 you said you wanted it to apply to all counters. (it just changes the counter print commands so a counter prints as one less than its value. ) Commented Aug 18, 2016 at 15:53
  • David, yeah, it does exactly what I wanted :)

  • I've found a minor issue with this. The reference list is printed starting from zero, which is nice, but along the text, the citations aren't synced: for instance, what is listed as [2] in the bibliography is mentioned as [3] along the text. Commented Aug 19, 2023 at 0:13
  • @RenanMezabarba ref works, I added an example. If \cite doesn't I think your bibstyle is doing something wrong, you could ask a new question. Commented Aug 19, 2023 at 0:26

You can use \LoopResetCounters from xassoccnt which sets all counters given in the comma-separated list to zero.

See the update for grabbing all counters defined with \newcounter and put them on a list at the end of this answer!

\documentclass{article}


\usepackage{xassoccnt}

\begin{document}

\setcounter{figure}{17}

\thefigure

\LoopResetCounters{page,section,subsection,figure,equation,subsubsection,table}

\thefigure

\end{document}

Update

I've grabbed the comment by David Carlisle and exploited the \cl@@ckpt list in order to reset the all counters to -1, but omitted the page counter there!

In order to make the resetting list work, the \@stpelt list must be changed at all.

No additional package is needed at all!

This procedure does not influence the secnumdepth and tocdepth counters since those are not defined with \newcount.

\documentclass{article}



\makeatletter
\newif\if@resetall
\@resetallfalse

\let\latex@newcounter\newcounter
\newcommand{\ResetAllCounters}[1][-1]{%
  \EnableResetAll
  \def\@elt##1{%
    \def\@tmp@@a{##1}
    \def\@tmp@@b{page}
    \ifx\@tmp@@a\@tmp@@b % Check if it is the page counter
    \setcounter{##1}{\z@}%
    \else
    \setcounter{##1}{#1}%
    \fi
  }%
  \cl@@ckpt% Loop through the list of all counters defined with \newcounter
  \gdef\@@resetvalue{#1}% Store the reset value
}

% Redefine the reset stepper \@elt - list marker
\let\latex@@stpelt\@stpelt

\def\@stpelt#1{%
  \if@resetall%
  \global\csname c@#1\endcsname \numexpr\@@resetvalue-1\stepcounter{#1}
  \else
  \latex@@stpelt{#1}%
  \fi
}%

\newcommand{\DisableResetAll}{%
  \global\@resetallfalse
}

\newcommand{\EnableResetAll}{%
  \global\@resetalltrue%
}

\setcounter{secnumdepth}{5}
\setcounter{tocdepth}{5}

\makeatother

  • I would have to populate the comma separated list manually though?

  • @user89: Yes, at the current state of the package. I did explicitly no changes to the \newcounter command (I am the author of xassoccnt by the way)

  • I noticed you're the author (I looked up the package)! Is there no way to change the default value at which counters are initialized to -1?

    latex already has a list of all defined counters, you don't need to redefine \newcounter to grab that see \show\cl@@ckpt Commented Aug 17, 2016 at 22:22
