% The \PackageName{} package counts how often a \LaTeX{} document is
% compiled.\\

%
% \section{Introduction}
% From a statistical perspective you maybe want to know how often you compiled
% a document. This is exactly the task I wrote this package for. For a few
% years I used a bash script and -shell-escape to do this but I decided to
% write this small package to do the trick a little nicer.
%
% \section{Usage}
% Just load the package placing
% \begin{quote}
%   |\usepackage{counttexruns}|
% \end{quote}
% in the preamble of your \LaTeXe{} source file.
%
% The counter will be stored in a file with the same prefix as your document
% (|\jobname|) but with the file extension \enquote{.ctr}. You can change the
% default extension by setting it as package option like this:
% \begin{quote}
%   |\usepackage[extension=ctr]{counttexruns}|
% \end{quote}
%
% \DescribeMacro{\thecounttexruns}
% To print the count you can use the macro |\thecounttexruns|. You can also use
% and even change the \LaTeX{} counter \enquote{counttexruns}. This will not disturb
% \PackageName.
%
% By the way this documentation was \thecounttexruns{}
% time\ifthenelse{\equal{\value{counttexruns}}{1}}{}{s} compiled during
% development.
%
% You can use the package \PrintPackage{ifthen} for checking if a counter is
% one: \\ |time\ifthenelse{\equal{\value{counttexruns}}{1}}{}{s}|
%
%

%
% \section{Implementation}
% \iffalse
%<*package>
% \fi
% \begin{macro}{\thecounttexruns}
% First a new counter and file handle is declared.
% The |\newcounter| will also declare the macro |\thecounttexruns|.
%    \begin{macrocode}
\newcounter{counttexruns}
\newwrite\@counttexrunsfile
%    \end{macrocode}
% Then the package options are processed.
%    \begin{macrocode}
\RequirePackage{kvoptions}
\DeclareStringOption[ctr]{extension}
\ProcessLocalKeyvalOptions*
%    \end{macrocode}
% \end{macro}
% Here it is checked if the file already exists and if that is the case the
% number of compile events will be stored in the \LaTeX{} counter
% \enquote{counttexruns}.
%    \begin{macrocode}
\IfFileExists{\jobname.\counttexruns@extension}{
  \immediate\openin\@counttexrunsfile=\jobname.\counttexruns@extension
  \immediate\read\@counttexrunsfile to \@counttexruns
  \immediate\read\@counttexrunsfile to \@counttexruns
  \immediate\closein\@counttexrunsfile
  \setcounter{counttexruns}{\@counttexruns}
}{}
%    \end{macrocode}
% Here the counter \enquote{counttexruns} is increment by one.
%    \begin{macrocode}
\stepcounter{counttexruns}
%    \end{macrocode}
% At this point the new count is written back to the file.
%    \begin{macrocode}
\immediate\openout\@counttexrunsfile=\jobname.\counttexruns@extension
\catcode`\%=11\relax
\immediate\write\@counttexrunsfile{%% This file
  '\jobname.\counttexruns@extension' was generated by the package counttexruns}
\catcode`\%=14\relax
\immediate\write\@counttexrunsfile{\arabic{counttexruns}}
\immediate\closeout\@counttexrunsfile
%    \end{macrocode}
